BruteForce: how do you open the Visual Studio Command prompt? By typing "Tools.Shell cmd" to the command window, or by another way?
I open it from the Tools menu. According to "External Tools..." dialog this runs: COMMAND: %systemroot%\\system32\\cmd.exe ARGUMENT: /K vcvars32.bat INITIAL DIR: C:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\vc\\bin
