Games For Windows Marketplace Client won't start problem

When my Games For Windows Marketplace Client would not start I found that installing Windows Live Essentials fixed the problem.

The Error I was getting:

Virtualdub Black Screen in Capture Mode

There are many reasons you could get a black screen although this worked for me. If you are getting a black screen in the Screen Capture mode of virtualdub try the following.

1. In menu bar click Video->Source->
2. uncheck "Use OpenGL hardware acceleration"
3. click ok

 This is using the inbuilt screen capture mode of virtualdub.

Microsoft Visual C# 2010 Express with ADO.Net Entitity data model conecting to SQL Server

Microsoft Visual C# 2010 Express has restricted functionality for connecting to SQL Server databases not allowing connection to a running SQL Server.

Microsoft Visual Web Developer 2010 Express does have this functionality enabled, so a work around can be creating an ADO.Net Entity Data Model in Microsoft Visual Web Developer 2010 Express, compiling and then adding the dll as a reference in your Microsoft Visual C# 2010 Express project.
