argc, argv from WinMain??

Can anyone tell me how to get the classic C command line arguments (argc,
argv) from a Windows application, whose entry point is the WinMain (or
AfxWinMain) function?

I don't want to have to write code for MFC CCommandLine functions because
the code already exists; I just need the argc, argv parameters as given by
the user.

Cheers,
Toby.

There are global variables available from WinMain, AfxWinMain,
ordinary main, Bangor Maine, or anywhere at all:

__argc - the number of command-line arguments entered.

__argv (__targv for the international version) - an array of
null-terminated character strings which holds as many entries as there
are command-line arguments entered.

In case it's hard to read, those are double leading-underscores.

With BC++ you can use _argv and _argc even in a win app.
If this doesn't fix your prob you can issue a call to GetCommandLine which is
not an mfc but a simple Win API function, so you don't need to re-target your
project.

I copied these lines from MSVC++ 5.0 help. I think this is what you need:

CWinApp::m_lpCmdLine
Remarks
Corresponds to the lpCmdLine parameter passed by Windows to WinMain. Points
to a null-terminated string that specifies the command line for the
application. Use m_lpCmdLine to access any command-line arguments the user
entered when the application was started. m_lpCmdLine is a public variable
of type LPSTR.

Good luck!

Don't know if I've missed earlier replies in this thread, but you can use
the global variables __argc and __argv (that's 2 underscores in front)

Actually m_lpCmdLine only gives you the arguments of the command line. If
command line is
"wordpad readme.txt", m_lpCmdLine = "readme.txt".

To get entire command line use GetCommandLine();
