The GetCommandLine function returns a pointer to the command-line string for the current process.
LPTSTR GetCommandLine(VOID)
Parameters
This function has no parameters.
Return Values
The return value is a pointer to the command-line string for the current process.
Remarks
Non-Unicode console processes written in C can use the argc and argv arguments to access the command-line arguments. The parameters of the command-line string, excluding the program name, are also available to such non-Unicode applications as a parameter of the WinMain function. The reason for the Unicode exclusion from these options is that WinMain, argc, and argv use the LPSTR data type for parameters, not the LPTSTR datatype.
如果是在SDK下,只需要象 mscf 所说的"判断winmain的命令行参数是否为空或符合你要的条件"就行了的,即
int WINAPI WinMain(
HINSTANCE hInstance, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // command line
int nCmdShow // show state
);
检查lpCmdLine即可.
