drop down (select) in HTML, DIV, and a little bit more about it.

to pimp my website with a suggestion text box can be very cool... the meaning behind it is to show suggestions based on user's input. As a AJAX.net fan, I downloaded Michales great suggestion box and have used it in combination with some other controls on my page... eh voila!

have you ever tried to make show a div over a drop-down? Microsoft's MSDN answer sounds like that:


Remarks
-The SELECT element is available in HTML and script, as of Internet Explorer 3.0.

-This element is a windowed control and does not support the z-index attribute or zIndex property.

-This element is an inline element.

-This element requires a closing tag.


so now i still have the same problem like before. but since i get used to display div's i did the following try:

My HTML part looks like that:
<div id="myDivStyle" class="divBoxing">some
more
information

<input id="text" maxlength="30" onfocus="myLoveleySelectBox(true);void(0);" onblur="myLoveleySelectBox(false);void(0);" />
<br/>
<select id="myDropDown" style="visibility:visible;">
<option value="a">A
<option value="b">B
</select>


the css for my suggestion can looks like that (div):
<style type="text/css">
.divBoxing
{
border-right: #000000 3px dashed;
border-top: #000000 3px dashed;
border-left: #000000 3px dashed;
border-bottom: #000000 3px dashed;
line-height: 100px;
line-width:140;
visibility:hidden;
position:absolute;
left:12px;
top:36px;
background-color:Teal;
color:White;
}
</style>


and here the last part, a little bit javascript
<script type="text/javascript" language="javascript">
function myLoveleySelectBox(b)
{
var l = document.getElementById("myDivStyle");
l.style.visibility = b ? "visible" : "hidden";

var l = document.getElementById("myDropDown");
l.style.visibility = !b ? "visible" : "hidden";
}
</script>


enjoy it!

Disabling a button for few seconds

I have founded today in my backups the following code:

<script type="text/javascript">
<!--
var secs = 20;
var wait = secs * 1000;
document.sform.submitbtn.disabled=true;

for(i=1;i<=secs;i++)
{
window.setTimeout("update(" + i + ")", i * 1000);
}

window.setTimeout("timer()", wait);

function update(num)
{
if(num == (wait/1000))
{
document.sform.submitbtn.value = "Akzeptieren";
}
else
{
printnr = (wait/1000)-num;
document.sform.submitbtn.value = "Akzeptieren (" + printnr + ")";
}
}

function timer() {
document.sform.submitbtn.disabled=false;
}
//-->
</script>

I don't have written the above code by myself... Anyway
thanks to the writer. Just tested it and its working very
good, in case you want that user reads a your lic. agreement
or anything else.

Mulitculiti with CurrentCulture and CurrentUICulture - Localization

to understand when exactly what is happening during the page life cycle is not very difficult but its also not very easy. Anyway, during some tests with the .net 2.0, CurrentCulture and CurrnetUICulture I got the following conclusions:

- CurrentUICulture is exclusively used by the Resource Manager
- CurrentCulture is used by the formatting methods like myDateTimeObject.ToString()

as I received a small example from a friend of mine which contained the following lines to understand this behavior.

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-us");
Console.WriteLine(DateTime.Today.ToString());

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("de-ch");
Console.WriteLine(DateTime.Today.ToString());

System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-us");
Console.WriteLine(DateTime.Today.ToString());

System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("pt-br");
Console.WriteLine(DateTime.Today.ToString());


well, I have to say; based on those lines i understand where the difference is! Thanks to "XiCoLoKo"

more information you can get at the following article: Localization Practices on TheServerSide.com


In my point of view the best approach will be using the Profile option which is provided by .net 2.0

the following is an extract from the article on theServerSide.com article I have pointed above:

Fortunately, with ASP.NET, a strongly-typed mechanism for storing profile data is available. For example, this web.config setting creates a profile that stores UICulture and Culture settings:

<profile>
<properties>
<add name="UICulture" allowAnonymous="true" />
<add name="Culture" allowAnonymous="true" />
</properties>
</profile>

These settings are accessible through the type-safe Profile object:

Profile.Culture = "it";
Profile.UICulture = "it";

Using profile, we are still faced with a similar challenge as with the Session object: when can we access the Profile for the user during request processing? Unfortunately the Profile is not initialized until the session is acquired, which means we cannot access it through the object model while the cache is inspected. In order to overcome this, the data store where user settings are persisted must be accessed using custom code.

What happens to the WebAdmin from the Visual Studio 2005?

Today I got a compiled solution from a friend in Asp.Net which is based on .Net 2.0.

Well great, this solution implements the Membership Model. This means first I have to register with a username, password, security question, etc.

But why the hack... I cannot login now. The answer is simple first i need to activate this user. That happens over the WebAdmin. But i dont have a solution i have just *.aspx and the releated *.dll's. How can I run now the WebAdmin for this web like I have it in the Visual Studio 2005?

There is a small trick you can do on your local machine. I don't know if its also works on a distributed environment but it works on my local machine well.


http://localhost/webadmin/default.aspx?applicationPhysicalPath=C:\Inetpub\wwwroot\cg\&applicationUrl=/cg

1) create a virtual directory at the root of your default website
2) name the virutal web "WebAdmin"
3) Set the Path of the virtual directory to
C:\WINDOWS\Microsoft.NET\Framework\%Your Framework Version%\ASP.NETWebAdminFiles
4) If you have already installed the release version your IIS is running with
the latest framework version otherwise change your running verison in the
ASP.Net tab in the Virtual Directory property.
[ i had also to set inside the Authentication Methods the
checkbox: Integrated Windows authentication. ]
5) now you have setup your environemnt set up to run it

http://localhost/webadmin/default.aspx?applicationPhysicalPath=C:\Inetpub\wwwroot\cg\&applicationUrl=/cg


translate it like that

- webadmin : name of your virtual directory
- applicationPhysicalPath: the path to your application on your pc
- applicationUrl: the virtual directory of your own application

Thanks to the author Jeff Widmer .

If you have a another option found inform me please.

UDPATE: in the meanwhile i developed my own webadmin. read more about it over here:
WebAdmin - Membership Management for ASP.NET MVC release 1.0

I thought google supports Firefox - unfortunately not!

google comes out a few day's ago with a new service: base [Base.google.com].

Wow, an amazing service for content search. I'm always were impressed how Google comes out with solutions and people just effort thousands of work hours to optimize their environment for them.

The new service efforts a content search, or how others would say: deep search. In past I worked for a company which creates box-office solutions, so I went directly to the Event section of base service.

I liked the redefine options which Google provides and forwarded it to a friend of mine [myself is using IE and he is a Firefox fan]. Back to the redefine search, there are some options like date limitations, which appears as a calender control in IE. The Look & Feel of Google is always simple and friendly and I have pointed to my friend to have a look at the this option. His answer was simple to understand:

what control do you speak about
.

After that I installed Firefox and was surprise to see that Google doesn't makes the effort to provide the same functionality to all internet users. what a pity for Firefox users!

Usage of Diagrams with SQL Server 2005 and compatibility level of: SQL Server 2000 (80)

Diagrams... yes I like them, to get a clear Idea of a DB I'm usually creating Diagrams. I got a DB from a friend which is working which works with SQL Server 2000 [80]. After I created an empty DB and restored the DB I tried to create an Diagram of its main tables. Every time I wanted to create a Diagram the following message appears:

Database diagram support objects cannot be installed because this database does not not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.


at least to me that sounds interesting.... So, naturally I searched for the following store procedure:


USE MyFriendsDatabaseNameIHaveCreated
EXEC sp_changedbowner 'sa'


After I have executed this store procedure I clicked on my new DB and .... again the same message.

I have checked the configuration of this Database I have imported which has a compatibility level of: SQL Server 2000 (80). After playing around with all the different properties I have found out that the Sql Server Management Studio is not able to create Diagrams as long the database runs with the compatibility level of: SQL Server 2000 (80). once you change that to the compatibility level of: SQL Server 2005 (90) you can create as much as you want diagrams.

The Database Diagram tool in SQL Server 2005 uses supporting objects that require SQL Server 2005 functionality. So the readme txt file say's in the documentation of SQL Server 2005. Here is an extract from this text:

To install database diagram support in SQL Server Management Studio, databases must be in SQL Server 2005 database compatibility level. Database
compatibility level can be reset after diagram support is installed.


I just should read the manual ;-)

DNS Step-by-Step Guide

This document can help you implement Domain Name System (DNS) on Microsoft® Windows Server™ 2003 on a small network. DNS is the main way that Windows Server 2003 translates computer names to network addresses. An Active Directory®-based domain controller also can act as a DNS server that registers the names and addresses of computers in the domain and then provides the network address of a member computer when queried with the computer's name.
This guide explains how to set up DNS on a simple network consisting of a single domain.

LogDump: CLRProfiler Log analysis tool

I get wondering how-to analyse the CLR profiler output and I have found the following link:

http://blogs.msdn.com/ricom/archive/2005/08/08/449246.aspx


Update:

Microsoft CLR Overview

The .NET Framework from Microsoft provides services to application developers that are necessary to quickly create scalable solutions that meet stringent requirements for security, manageability and productivity. This whitepaper introduces the guiding principles and thoughts behind the .NET Framework, the core features of the Common Language Runtime and its supporting Framework Base Class Libraries and how it is evolving in the next major version.

The Microsoft Common Language Runtime (CLR) and the .NET Framework class libraries – collectively called the .NET Framework – were designed to enable developers to easily create scalable, secure, interoperable and manageable applications that can also leverage existing investments in other technologies and platforms. The .NET infrastructure works with non-Microsoft technologies through its built-in support for creating and consuming Web services, and it works with existing Microsoft technologies by providing native integration with COM components. These features help to extract further value from an organization’s existing investments in prior technologies and ensure interoperability with other platforms.

Since the earliest days of software development, organizations have sought to build applications quickly and with higher quality – that is fewer bugs. Applications should also interoperate with different environments and technologies and should be built with widely-accepted languages that are easy to learn and maintain, simultaneously boosting productivity. Many approaches have appeared to try to improve the development process, but often these efforts have been focused on the analysis and design phase. It is not until more recently that the underlying architecture of the development platform itself has achieved a prominent role in laying the groundwork for building enterprise applications.

Whether an enterprise is concerned with interoperability with Web services or COM applications, building solutions more quickly and with fewer bugs, or using a common programming model across application types and languages, the .NET Framework provides organizations the tools to meet all these goals and more.

Asp.Net 2.0 Themes und URL-Rewriting

this is a well know problem with the relativ path's. Themes are using by default relativ Paths. the workaround is to use the follwoing method:

the reg-ex which is used here: ""

Notice: its just match css-links like in the sample!!!!

public override void Write(byte[] buffer, int offset, int count){string strBuffer = System.Text.UTF8Encoding.UTF8.GetString(buffer, offset, count);
// ---------------------------------// Wait for the closing tag// ---------------------------------Regex eof = new Regex("", RegexOptions.IgnoreCase);
if (!eof.IsMatch(strBuffer)){responseHtml.Append(strBuffer);}else{responseHtml.Append(strBuffer);
string finalHtml = responseHtml.ToString();Regex re = null;
// Css-Files auf die absolute Client-URL mappenre = new Regex("", RegexOptions.IgnoreCase);finalHtml = re.Replace (finalHtml, new MatchEvaluator (CssMatch));
// Write the formatted HTML backbyte[] data = System.Text.UTF8Encoding.UTF8.GetBytes(finalHtml);
responseStream.Write(data, 0, data.Length);}
}
private string CssMatch(Match m){return m.ToString().Replace(m.Groups[1].Value, ConfigurationManager.AppSettings["ApplicationRoot"] + m.Groups[1].Value);}

Workaround for ASP.NET 2.0 bug: LoadControl gives an exception in a TemplateControl

[since june CTP 2005 this bug is not available anymore]

http://blogs.infosupport.com/raimondb/archive/2005/04/29/203.aspx?Pending=true

ASP.NET - Relative Url's

ASPX:


HTML Client output:

somewhere else, not inside the control you can use the ResolveUrl("~/bilder/spacer.gif");

Masterpages per Browser

yes its possible to generate for each differnent browser its own MasterPage.

<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
ie:MasterPageFile="~/MasterPage_IE.master"
mozilla:MasterPageFile="~/MasterPage_Firefox.master"
%>

ASP.NET 2.0 URLMappings

do we need a special url? as short as possible?

so make from:

http://www.xyz.ch/testApp/testApp1/Version51/thisIsASamplePageWhatEverItIs.aspx

http://www.xyz.ch/myPage.aspx


mappedUrl="~/testApp1/Version51/thisIsASamplePageWhatEverItIs.aspx"/>

MasterPage, How-To change it on the fly

surely you can also change your masterPage on the fly. the only thing which has to be done is the following thing:

NOTICE: think about the page cicle!!!!

protected override void OnPreInit(EventArgs e){object tpl = Request.QueryString["Template"];if (tpl == null tpl.ToString() == "Default"){this.MasterPageFile = "~/Templates/Category/Standard.master";}else{this.MasterPageFile = "~/Templates/Category/Sample.master";}}

JavaScript Debugging

Clear the "disable script debugging" checkbox in Internet Explorer's advanced properties. Add the keyword "debugger" somewhere within your JavaScript.When you run the web page from Visual Studio in debugging mode, viola--when it hits the "debugger" statement, the Visual Studio debugger window takes control, you can set your break points, and proceed as normal. You can even get very clever setting the "debugger" from within script created from you server-side code that's registered with one of the many "Register" client-side script block methods.

How-To handle RoleManagment features with my own Database

The role-based features in .net 2.0 are using some place to maintain the data. By default this will be the "SQL Server Express" instance which is automatically installed with the Visual Studio. If you dont make this wizard every try will end in the express version :-( - get sad from it but after several researches I have found the solution.

If you would like to use your own DB then go through the follwoing steps:

1 - Create DB
2 - Start -> Programs -> Microsoft Visual Studio 2005 ->
Visual Studio Tools -> Visual Studio 2005 Command
Prompt
3 - write "aspnet_regsql"
4 - Go through the Wizard
5 - Open your Web.Config file and add the following elements:



6 - Run now from your Visual Studio the WebSite / ASP.Net
Configuration [ WebAdmin Tool ]
7 - At the Security you should now choose the Authentication
type, adding your roles and user

thats the whole trick behind it.

javascript "loop through all the options and test each one until"

You have to loop through all the options and test each one until you find
it, this example assumes you're testing against text value:

function setListbox(name, value, caseSensitive)
{
var oList = document.forms['abc'].elements[name];
var sTestValue = (caseSensitive ? value : value.toLowerCase());
var sListValue;
for (var i = 0; i < oList.options.length; i++)
{
sListValue = (caseSensitive ? oList.options[i].text :
oList.options[i].text.toLowerCase()); //change text to value if you wish to
compare by value of listbox.
if (sListValue == sTestValue)
{
oList.selectedIndex = i;
break;
}
}



}


setListbox("Country", "Canada", true);

SQL Server 2005, SPROC

well i were wondering how to make sprocs in C# and i found the following page:

http://www.dotnetfun.com/articles/sql/sql2005/SQL2005CLRSProc.aspx

Thursday, July 21, 2005

Page directive

The page directive in the code behind version contains the attribute to corresponding source code file over attribute CompileWith="xxxx" and the class in the source code attribute="xxxx"

<@% Page CompileWith="YourPage.aspx.cs" ClassName="YourClassName"%>

Notice that the new class is a partial class which doesn't contains all information
you were used to it in version 1.x.

partial classes derives from System.Web.UI.Page.

Sample:

using System;
using System.Web;

.....


public partial class YourWebSite_aspx
{
void foo()
{
// your stuff goes here.....
}
}

the following link describes you this and some additional new features:

http://www.c-sharpcorner.com/Code/2004/July/WhidbeyFeatures.asp


If you wonder how the whole construct works you can do a research about
"Dynamic Page Compilation".

Code Inline vs. Code Behind

Microsofts IDE Visual Studio 2005 supports both models of writing code.

Code Inline - means that all your code is insise the *.aspx
Code Behind - means that all your code is separeted into two or MORE files.
*.aspx just contain markup data

by code behind selection you will generate a *.vb or *.cs file


Microsfts pronounced - is no performance difference between inline or behind option.

check Querystring parameters

today i found the following method inside the String class:

if(!String.IsNullOrEmtpy(this.Request["myQuerystringParameter"]) )
{
// here goes your code

Background of the Rational Unified Process

Background of the Rational Unified Process
The writers or developers of this software engineering process focused on diagnosing the characteristics of different software projects that failed; by doing this they tried to recognize what the common aspects were that made these software projects fail. They also looked at the existing software engineering processes and their solutions for these symptoms that caused the failure of these projects.

The symptoms are:

Ad hoc requirements management .
Ambiguous and imprecise communication
Brittle architecture
Overwhelming complexity
Undetected inconsistencies in requirements, designs, and implementations
Insufficient testing
Subjective assessment of project status
Failure to attack risks
Uncontrolled change propagation
Insufficient automation
Project failure is caused by a combination of several symptoms, though each project fails in a unique way. The outcome of their study was a system of software best practices they named the Rational Unified Process. Since knowing these problems will not guarantee a successful software product unless the solutions are also considered, they went on to create the Rational Unified Process Product (RUPP).

The Process was designed with the same techniques the team used to design software; it has an underlying object-oriented model, using Unified Modeling Language UML.

Retriving Data from AssemblyInfo.cs

How to get data from the AssemblyInfo.cs can be made by a helper class inside the Assembly file:

Class1.cs

public class MyWinForm:System.Windows.Forms.Form
{
[STAThread]
static void Main()
{
Application.Run(new MyWinForm());
}

// its contains much more then the Main method but for this sample its enough.

}




AssemblyInfo.cs

// that part is generated auto. by visual studio
using System;
using System.Reflection;

[assembly: AssemblyTitle("Your Custom Assembly Title")]
[assembly: AssemblyDescription("Some information about your Assembly")]
[assembly: AssemblyCompany("Your Company Name")]
[assembly: AssemblyProduct("Your Product Name")]
[assembly: AssemblyCopyright("Who has the copyright")]
[assembly: CLSCompliant(true)]
[assembly: AssemblyVersion("1.0.0.0")]

#region Helper class

// Your generated class does not contain the follwoing part.
public class AssemblyInfo
{
// Used by Helper Functions to access information from Assembly Attributes

private Type myType;
public AssemblyInfo()
{
myType = typeof(MyWinForm);
}
public string AsmName
{
get {return myType.Assembly.GetName().Name.ToString();}
}

public string AsmFQName
{
get {return myType.Assembly.GetName().FullName.ToString();}
}

public string CodeBase
{
get {return myType.Assembly.CodeBase;}
}

public string Copyright
{
get {
Type at = typeof(AssemblyCopyrightAttribute);
object[] r = myType.Assembly.GetCustomAttributes(at, false);
AssemblyCopyrightAttribute ct = (AssemblyCopyrightAttribute) r[0];
return ct.Copyright;
}
}

public string Company
{
get
{
Type at = typeof(AssemblyCompanyAttribute);
object[] r = myType.Assembly.GetCustomAttributes(at, false);
AssemblyCompanyAttribute ct = (AssemblyCompanyAttribute) r[0];
return ct.Company;
}
}


public string Description
{
get
{
Type at = typeof(AssemblyDescriptionAttribute);
object[] r = myType.Assembly.GetCustomAttributes(at, false);
AssemblyDescriptionAttribute da = (AssemblyDescriptionAttribute) r[0];
return da.Description;
}
}


public string Product
{
get
{
Type at = typeof(AssemblyProductAttribute);
object[] r = myType.Assembly.GetCustomAttributes(at, false);
AssemblyProductAttribute pt = (AssemblyProductAttribute) r[0];
return pt.Product;
}
}

public string Title
{
get
{
Type at = typeof(AssemblyTitleAttribute);
object[] r = myType.Assembly.GetCustomAttributes(at, false);
AssemblyTitleAttribute ta = (AssemblyTitleAttribute) r[0];
return ta.Title;
}
}

public string Version
{
get {return myType.Assembly.GetName().Version.ToString();}
}
}
#endregion


Now back to the "Class1.cs" where we see how to use it:

public class MyWinForm:System.Windows.Forms.Form
{



public void SetAnAssemblyInfoToControlOfYourChoice()
{
AssemblyInfo ainfo = new AssemblyInfo();
string title = ainfo.Title;
this.YourControlInstance.Text = string.Format("{0} ...", ainfo.Title);
}

What is EAI?

EAI refers to Enterprise Application Integration. EAI is the merging of applications and data from various new and legacy systems within a business. Various means are employed to accomplish EAI, including middleware, in order to unify IT resources, maximise new ERP investments, diminish errors and get everyone on the same page. EAI enables companies to link their existing software applications with each other and with portals. EAI provide the ability to get their applications to exchange critical data. EAI is usually close to the top of any CIO's list of concerns. There are different approaches to EAI. Some rely on linking specific applications with tailored code, but most rely on generic solutions, typically called middleware. XML, combined with SOAP and UDDI is a kind of middleware.

Article about restoring db's

http://www.devx.com/getHelpOn/10MinuteSolution/16503/1954?pf=true

coding guidelines

The following Code-Guidelines is an extract which I took form a german .Net magazine. My personal point of view of those guidelines makes really sense the develope such lines for coding.

coding collections:

describe genereal basic classes and how you should use them.

  • How do you use the Exeption Handling
  • How do you protokoll failers? Where do you handle failures and finally which data is going to be listed.
  • How do you make Database access. Capsulation of classes, DB mng. they're abstract or build in.
Naming Convensation
  • Namespaces, Structures
  • Filesystem, organisation of projectfolders and filenames
  • prepare lines for files, namespaces, assemblies, classes, methods, parameters, variables, properties, constants, forms, controls

Object Oriented

  • prepare lines what kind of properties, methods etc. can be public, protected, private ....
  • Factor (addition of code which can be used in same baseclasses)
  • usage of abstract classes
  • usage of interfaces
  • overloading
  • how deep its allowed to inherit

Qualityaspects

  • size of classes, methods, files, namespaces & assemblies (normaly we speak about LLOC - logical lines of code)
  • define complexity of classes and methods
  • dont allow constucts like typeof() - its usage is to use over polymorphism

Formating

  • size of files, classes, methods und lines
  • tabulator
  • comments
  • etc.

Legimitation of non allowed constructs

  • exeptions always happens in a any kind of project. if this case happens try to comment and explain why its happens and maybe give a sample or somehting simular
  • add links to articles (create a knowleage bases available with links from your code)

Clean .Net Environement

In my point of view, environments for Java and .Net has today all needed components to create a clean environment – most on it is free or comes built in with other components like VS.Net or the SQL Server Desktop Tools.

What do I mean with clean Environment; you should set your focus as much as possible on automation in generation and testing.

Which elements should I integrate when I create new environments? After several months, and I believe I spent quite high invest to make the researches I got finally my decision:

Microsoft Environment:

FxCop -> from Microsoft got from their Design Rules quite lot of new inputs.
Nant -> automatically compilation.
NUnit -> automatically testing
XmlUnit -> automatically testing
CLR Profiler -> CLR profiling
SQL Query Analyzer -> SQL profiling
MS Application Center Test -> installed with VS.Net
Cruise Control -> continuous build process

Java Environment:

CruiseControl
CheckStyle
JUnit
Jester
JCoverage
FindBugs
Ant
Maven

I'll concentrate myself on MS tools and not on Java. So dont search inside this blog about Java realted stuff.

NUnit: Suites & Categories

using NUnit.Framework;
using NUnit.Core; // requieres nunit.core.dll

[TestFixture]
public class TestClassSuite
{
[Suite]
public static TestSuite Suite
{
get{
TestSuite suite = new TestSuite(@"Give it a name");
suite.Add(new Test1());
suite.Add(new Test2());
// add more test cases
return suite;
}
}
}

The classes you add to the suite (Test1 , Test2 and so on), are marked as [TestFuxuture] classes. Within each of these classes you still have the [Test] attribute on individual mehtods, and the framework will run those automaitcally. The suite facility doesn't stop you running the individual fixtures when you want. But they also let you group those fixtures: by running the one Suite(), you can now run a whole bunch of test fuxtures at once.

suites are a useful machanism for composing tests hierachically, which can be handy for coordinating sets of tests especially for an unattended build.

But it's not that useful a mechanism for day-to-day testing. You would like to be able to cross-cut across all the tests and select or exclude certain kinds of tsests from the vast pool of existing test you have written.

NUnit forces also another mechanism you can use to categroize ansd classify individual test methods and fixtures.

Categories

For instance, suppose you have got a few methods that only take a few seconds to run, but one method that takes a long time to run. You can annotate them using the category attribute.


using NUnit.Framework;
using NUnit.Core;

[TestFixture]
public class SampleCategory()
{
[Test]
[Category("ShortTest")]
public void TestMethod1()
{
// suppose this takes 1 min.
}

[Test]
[Category("ShortTest")]
public void TestMethod1()
{
// suppose this takes 1 min.
}

[Test]
[Category("ShortIntensiv")]
public void TestMethod3()
{
// suppose this takes 3 hours.
}
}

isn't it great . . . . . .

Do you have a problem to Debug WebSolutions after .Net 2.0?

Well, after a whole evening i found out the solution to this problem.

- Open Computer Managment
- Choose IIS-> Web Sites-> Default Web Sites
- Choose your Web and open the Properties

You can see the additional Tab: ASP.NET

Just change now from 1.1.XXXXX to 2.0.XXXXXX.

Enjoy to go on with .Net 1.1

Customised sorting of an ArrayList (C#)


A handy feature that was included in ArrayList's, is the ability to sort the list according to your own comparison criteria. Unfortunately the documentation is a bit scarce on exactly how to implement this, of which an example wouldn't have gone awry.

The first thing you need to start with is the object to store in your ArrayList, for this example I have put together a simple object call Person (Person.cs). This object one contains two member variables, Name and Age.

using System;

namespace SortArrayListCS {

public class Person {
public string Name;
public int Age;

public Person() {
}

public Person(string name, int age) {
this.Name = name;
this.Age = age;
}
}
}

Now we need to implement the infamous IComparer interface to define how we want to sort this. Whilst I have made this a little more elaborate than it need be, I wanted to show how you can further define how you want to sort this collection.

Our comparer is called PersonComparer (PersonComparer.cs), and we also have a enum called SortDirection which allows us to define whether we want to sort Ascending or Descending.

using System;
using System.Collections;

namespace SortArrayListCS {

public enum SortDirection {
Ascending,
Descending
}

public class PersonComparer : IComparer {

private SortDirection m_direction = SortDirection.Ascending;

public PersonComparer() : base() { }

public PersonComparer(SortDirection direction) {
this.m_direction = direction;
}

int IComparer.Compare(object x, object y) {

Person personX = (Person) x;
Person personY = (Person) y;

if (personX == null && personY == null) {
return 0;
} else if (personX == null && personY != null) {
return (this.m_direction == SortDirection.Ascending) ? -1 : 1;
} else if (personX != null && personY == null) {
return (this.m_direction == SortDirection.Ascending) ? 1 : -1;
} else {
return (this.m_direction == SortDirection.Ascending) ?
personX.Age.CompareTo(personY.Age) :
personY.Age.CompareTo(personX.Age);
}
}
}
}

If you wanted to sort an ArrayList of mismatched objects which have a common field, you would design an interface that each of those objects implement, then change the comparer to cast these objects as their interface.

Finally we need to test this to make sure everything is working as it seems. I knocked this together as a Console Project (C#) just to be quick and simple, so our test file is SortArrayList.cs.

using System;
using System.Collections;

namespace SortArrayListCS {

class SortArrayList {

[STAThread]
static void Main(string[] args) {

ArrayList list = new ArrayList();
list.Add(new Person("John", 50));
list.Add(new Person("Mary", 28));
list.Add(new Person("William", 12));
list.Add(new Person("Marcia", 17));
list.Add(new Person("Rodrick", 36));

list.Sort(new PersonComparer());

Console.WriteLine("Sort Ascending");
foreach (Person person in list) {
Console.WriteLine("Name: " + person.Name + ", Age: " + person.Age.ToString());
}

list.Sort(new PersonComparer(SortDirection.Descending));

Console.WriteLine("\n\rSort Descending");
foreach (Person person in list) {
Console.WriteLine("Name: " + person.Name + ", Age: " + person.Age.ToString());
}

Console.ReadLine();
}

}
}

If all of this worked as planned you should see the following output:

Sort Ascending
Name: William, Age: 12
Name: Marcia, Age: 17
Name: Mary, Age: 28
Name: Rodrick, Age: 36
Name: John, Age: 50

Sort Descending
Name: John, Age: 50
Name: Rodrick, Age: 36
Name: Mary, Age: 28
Name: Marcia, Age: 17
Name: William, Age: 12




===============================================================================
Maybe it wouldn't a better choice to avoid overhead/exceptions from trying to cast null's be:

int IComparer.Compare(object x, object y) {

if (x == null && y == null) return 0;
if (x == null && y != null)
return (this.m_direction == SortDirection.Ascending) ? -1 : 1;
if (x != null && y == null)
return (this.m_direction == SortDirection.Ascending) ? 1 : -1;

Person personX = (Person) x;
Person personY = (Person) y;

return (this.m_direction == SortDirection.Ascending) ?
personX.Age.CompareTo(personY.Age) :
personY.Age.CompareTo(personX.Age);
}
}
}
}
