    Im not sure if parameter is the right word. for example: If you run an exe-file through cmd.exe: "C:\testfile.exe -wnd" parameter = "wnd"

    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; }

      With MFC? Look at CWinApp::m_lpCmdLine. Without MFC? Look at lpCmdLine in WinMain

          Are you wanting to know within testfile.exe what parameters were passed to it, or are you wanting to know from some other application what parameters were passed to testfile.exe? There is a big difference.

            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?

              oh, you are wanting what are the arguments that a program can have/use, no ? I think that for normal DOS type programs, you can do somthing like cmd.exe /? which will list the available arguments. maybe some program will have the following format : someprogram.exe -h or someprogram.exe --help

                Its a Win32 program. So, is it possible to get arguments through VC++ or something?

                    Technically there is a difference between parameters and arguments. Most folks use them interchangeably, and thus can lead to confusion.

                        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.

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

                              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. :)

                                You can also access __argc and __argv in windoze applications both with and without MFC. Just include stdlib.h. I recommend checking the source code for CCommandLineInfo for more enlightenment on this issue. :)
