Where has argv[] gone in WinMain?

In a console VC++ application it is possible to read the argv[1] argument to
retrieve the path of the file that has been drag&dropped onto the executable
file. Likewise I can get the path of the running process by argv[0].

What is the equivalent methods using the Win32 WinMain( ) procedure?

Thank you in advance for your help,
Teis

GetCommandLine
And for NT an later: CommandLineToArgvW


You can also use MFC to retrive the commandline
(See CCommandLineInfo class)

Do you need a memory-leak finder ?

You can call:

char szPath[MAX_PATH];
DWORD cbPath = GetModuleFileName(NULL, szPath, sizeof(szPath)-1);
// now szPath contains the path + filename of your executable

HTH,

Thanks you for replying Jochen and Sven.
I realize that there are multiple ways to do this.
I discovered that I can simply call the somewhere predefined '__argv[]' and
'__argc' which appears similar to their argv, argc console counterparts.
That seems somewhat easier -is that cheating? Can I expect any issues using
them?

thanks, Teis

Als long as you use the CRT as "Main-Entry-Point" you can use it:
