Asp.Net: Webtest trough proxy (WebTestPlugin)

The test-team came to me with a problem involving connection errors while running webtests trough the company proxy. The webrequest needed to go to the webproxy including authentication. Visual Studion 2008 doesn’t support proxy authentication out of the box, but you can create a WebTestPlugin that does the authentication for every request.

The following class inherits from WebTestPlugin and overrides the PreWebTest method. In the PreWebTest method it will authenticate the request with your credentials.


public class LoadTestProxyAuthentication : WebTestPlugin
{
        public override void PreWebTest(object sender, PreWebTestEventArgs e)
        {
            // Create WebProxy (enter your proxy url)
            WebProxy webProxy = new WebProxy("ProxyAdres");

            // Use the proxy for the webtest
            e.WebTest.WebProxy = webProxy;

            e.WebTest.PreAuthenticate = true;
            NetworkCredential proxyCredentials;

            proxyCredentials = new NetworkCredential();

            proxyCredentials.Domain = "domain";
            proxyCredentials.UserName = "username";
            proxyCredentials.Password = "password";
            e.WebTest.WebProxy.Credentials = proxyCredentials;
        }
 }

How to use the webtestplugin
Ad the class to your test project, change the credentials and proxyadres. After a build open the webtest press the ‘add  Webtest plugin’ button (on the top screenmenu), select the LoadTestProxyAuthentication and press OK. You need to add the webtestplugin for every webtest.

Now you can run your webtests trough the proxy.

Hope it helps,

Asp.Net: keyboard sort items

As proof of concept I wanted to sort images in a Grid by keyboard. The sort logic needed to be implemented on the server. My solution for this problem is a combination of Javascript and C#.

First add following html to you .aspx. Notice that the body tag has runat=”server” and a ID.


&lt;body<strong> runat="server" ID="bodyTag"</strong>&gt;
<form id="form1">

<br />


<br />
<br />

</form>

Now add the following JavaScript to your page. This script will fetch all keyboard input and press the corresponding button.



document.onkeydown = checkKeycode
function checkKeycode(e) {
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
switch (keycode) {
case 37:
var obj = document.getElementById('');
obj.focus();
obj.click();
break;
case 38:
var obj = document.getElementById('');
obj.focus();
obj.click();
break;
case 39:
var obj = document.getElementById('');
obj.focus();
obj.click();
break;
case 40:
var obj = document.getElementById('');
obj.focus();
obj.click();
break;
}

}

At last we need to add the following C# code to the page.


protected void Page_Load(object sender, EventArgs e)
{
//Ad clientside onkeypress event to the body
bodyTag.Attributes.Add("OnKeyPress", "keyhandlers()");
}

protected void DownButton_Command(object sender, CommandEventArgs e)
{
//Just for testing
clickedLabel.Text = (string)e.CommandArgument;
}

Enjoy, Pieter

XBOX 360 friends status APP

After seeing a great XBOX360 friends Iphone App I decided to build a Windows Mobile version of it. The app shows your friends, their avatar, online status and what they are playing. After downloading the VS plugins for Windows Mobile development I started building the app. Building Windows Mobile Apps is easy. The only thing you need to know is that you can never build a application which have the same user experience and GUI as a Iphone. Maybe Windows Mobile 7 and XAML will fix this.

Here is result of one night programming. Clearly it is not finished but it`s a fun app. The application features are:

  • friend overview, see status of your friends
  • settings page, where you can set the polling time
  • An exit button, to clear te memory.
  • It even gives an alert when a friend comes online.

What I would like to add:

  • XML for your friendlist (it is hard coded now)

Here are some screenshots of the application.

And you can download the sourcecode here.

C#: Get Parent Control with Generics

I use the following method to return a parent control of a specific type. This method is recursive and uses generics.

<br />
private Control GetParentControl(Control control)<br />
{<br />
if (control.Parent.GetType() == typeof(T1))<br />
{<br />
return control.Parent;<br />
}<br />
else<br />
{<br />
return GetParentControl(control.Parent);<br />
}<br />
}</p>

MemoryStream to Byte Array (Byte[])

With the following code you can convert your MemoryStream to a Byte Array.


//create new Bite Array
byte[] biteArray = new byte[memoryStream.Length];

//Set pointer to the beginning of the stream
memoryStream.Position = 0;

//Read the entire stream
memoryStream.Read(biteArray, 0, (int)memoryStream.Length);

Gaatverweg.nl travelportal live

A few years after building the free travelblog site Globallog.nl in PHP. I started building a new version in .Net together with Mark. Although this was a joyful and educational experience, we never finished this project… Now a few years later I finished a new travelblog portal; Gaatverweg.nl.

Gaatverweg.nl is build with WordPress MU (php) and uses multiple WordPress plugins and a few custom build plugins.

Create a Visual Studio add-in with contextmenu and selected text as input

Create a Visual Studio add-in with contextmenu and selected text as input

When working with a new way of storing settings in a database. I was frustrated how much work it was to check the value of setting from code. So I deceided to make my life a bit easier by creating a VS2008 contextmenu add-in. With this add-in I can select text within VS and use the value of the selected text within the add-in popup. The hardest part was figuring out how to create a contextmenu and how to use the selected text as input value.

In this blogpost I will show how to create a Visual Studio contextmenu add-in and pass the selected text to the pop-up. I’m not going to explain how to create an add-in you can easily find articles about this on MSDN or blogs (just try Google).

Now let’s get started. Create an new Visual Studio add-in project and add the following code to the OnConnetion Method within the Connect.cs. This code will insert add the contextmenu.


_applicationObject = (DTE2)application;
CommandBars cBars = (CommandBars)_applicationObject.CommandBars;

CommandBar editorCommandBar = (CommandBar)cBars["Editor Context Menus"];
CommandBarPopup editPopUp = (CommandBarPopup)editorCommandBar.Controls["Code Window"];

Command command = commands.AddNamedCommand2(_addInInstance,
 "GetSetting", "Bekijk Setting", "Executes the command for test", true, 733, ref contextGUIDS,
 (int)vsCommandStatus.vsCommandStatusSupported + (int)vsCommandStatus.vsCommandStatusEnabled,
 (int)vsCommandStyle.vsCommandStylePictAndText,
 vsCommandControlType.vsCommandControlTypeButton);

Then to get the selected text I use the following method within the Exec of the Connect.cs and pass the selected text (return value) to a property of a Windows Form pop-up.


private string GetSelection()
{
    string setting = "";

    //Check active document
    if (_applicationObject.ActiveDocument != null)
    {
        //Get active document
        TextDocument objTextDocument = (TextDocument)_applicationObject.ActiveDocument.Object("");
        TextSelection objTextSelection = objTextDocument.Selection;

        if (!String.IsNullOrEmpty(objTextSelection.Text))
        {
 //Get selected text
            setting = objTextSelection.Text;
        }
    }
    return setting;
}

Hope it helps.

Cheers,
Pieter
