SYMPTOMS
When you run the Visual Basic .NET or Visual Basic 2005 QuickStart TestClient.exe sample on Microsoft Windows NT 4.0, the sample stops responding (hangs) before the page is loaded in Microsoft Internet Explorer.

The TestClient.exe sample is located in the following folder:

..\Program Files\Microsoft Visual Studio .NET\ FrameworkSDK\Samples\QuickStart\Howto\Samples\Interop\Testclient_2\VB

Note In Visual Studio 2005, the TestClient.exe sample is located in the following folder:

..:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\QuickStart\howto\samples\interop\testclient_2\vb



CAUSE
This problem occurs because the Console.Readline method does not pump messages on Windows NT 4.0 because of the operating system implementation.



RESOLUTION
To resolve this problem, follow these steps:   In TestClient.vb, locate the following line of code: Imports System.Runtime.InteropServices and insert the following code after this line: Imports System.Threading   In TestClient.vb, locate the following code webBrowser.GoHome and insert the following code after this line: Thread.CurrentThread.Join   In TestClient.vb, remove the following section of code: Console.WriteLine(&quot;Press Enter to quit&quot;) Dim s As String = Console.ReadLine Do While s <> &quot;&quot; s = Console.ReadLine Loop  If you have the project open in Microsoft Visual Studio .NET or Visual Studio 2005, on the Build menu, click Rebuild All.

Alternately, you can follow these steps to use Make files to rebuild the project:  From the Visual Studio .NET or from the Visual Studio 2005 command prompt, run the nmake command to rebuild the TestClient.vb file in the ..\Testclient_2\VB directory. Run TestClient.exe to run the sample.</li> To stop running the sample, close the browser window manually, and press the CTRL+C key combination to free the command window.</li></ol> </li></ol>
