Cannot run a small application

[WCheung]

I am a software developer. I usually use VirtualBox to test my application in a 32-bit Windows environment. I attached two zip files of my sample C# projects. The first one, ExpStarter.exe, loads the second file, ExpWorker.dll, dynamically and calls a function of it. These files works fine under Microsoft VirtualPC and real 32-bit WinXP environment. But, they fails in VirtualBox. This is why I think that there is some bug in VirtualBox which prevents them to run correctly. The attached zip files contain the source code and project files of these two files so that you can see what I use in the files. The exe and dll files are also in the zip files so that you can try in VirtualBox.
