How to get the command line argu

Use GetCommandLine(), which returns the name of the file being executed, followed by the arguments.

The application member m_lpCmdLine (used like yourApp.m_lpCmdLine) contains only the arguments.

There is also CWinApp::ParseCommandLine() that you may find useful.

Also try the ATL COM wizard to create a non-MFC dialog application (chose the .exe option, not .dll).
