Can anyone please tell me what is wrong?

You are using str_Group, str_Command, GroupBox and CommandBox variables in CAboutDlg class, which are declared in CUSBDlg class, so compiler doesn't recognize them.

Thanks alot. Solved the problem. But now i have another 1. I installed the LibUSB-win32 project. However, i can't seemed to include <usb.h> The compiler keep on throw error fatal error C1083: Cannot open include file: 'usb.h': No such file or directory. error message, which pisses me off. How am i going to solve this problem.

There's a project property where you can specify the directories the compiler will search for header files. Alternately, you could specify the full path to the header file in the #include statement.
