parameters

thanks Its parameter the right name for this?
Technically there is a difference between parameters and arguments. Most folks use them interchangeably, and thus can lead to confusion.

How do you call this what I want? arguments or parameters?

void foo( int x ) // the parameter is x
{
}void main( int argc, char *argv ) // the parameters are argc and argv
{
foo(123); // the argument is 123
}if this program were started at a command prompt like myprog.exe -excavator, the argument would be -excavator.

FOR EXAMPLE: This testfile.exe is normaly running in fullscreen. But it has parameters wich can be used to run it in a small windows size. The problem is: How do you get those parameters?

CCommandLineInfo cmdInfo; ParseCommandLine(cmdInfo); cmdInfo.m_strFileName now contains the commandline.

CCommandLineInfo, it would not show up in any of the member variables.

you need to do this from the source code, not from the command line ( or if that's the case, juste copy paste the arguments ) from the a simple C or C++ source code :
int main ( int argc, char* argv[] ) { /// argc is the number of arguments /// argv is the string containing the arguments. /// argv[0] is the program /// from argv[1] are the arguments /// you need to parse them manually. }from a MFC application :BOOL YouApp::InitInstance() { /// use the CCommandLineInfo class. CCommandLineInfo cmdLineInfo; }

You can access __argc and __argv in Win32 applications also. This is what MFC does in CCommandLineInfo and why I rarely use it myself. You end up peeling the args back apart so I see little point to it. BTW - if you don't believe me then check the MFC source code. :)

Thank you very much for your suggestions. Could you tell me your theory how you think it should be done?

As was mentioned here, -Dy has already answered your question for both MFC and non-MFC. What else are you looking for?
