Look up the following families of functions:
CreateProcess[Ex]
spawn
exec

I recommend using the _exec-family, because the parameters actually WORK. I've had trouble using more than 1 parameter with the other functions.

Clicky!

Or if you want to stay within the Standard you could try std::system(). It doesn't give you that much control but might be sufficient if you don't have complex needs.

No! No no no! USE _EXECx()!!
It's the best for launching games with parameters.

Problem: std::system blocks the parent process, which means that you can start the subprogram and then continue work in the parent. The others are non-blocking. For Windows, I prefer CreateProcessEx because of the level of control it provides.

i appreciate the responses but the description at the dev site is really confusing...can anybody give me a somewhat "lame-mans" example/explanation? thanks :)

// crt_args.c/* Illustrates the following variables used for accessing * command-line arguments and environment variables: * argc  argv  envp * This program will be executed by crt_exec which follows. */#include <stdio.h>int main( int argc, /* Number of strings in array argv */ char *argv[],       /* Array of command-line argument strings */ char **envp )       /* Array of environment variable strings */{    int count;    /* Display each command-line argument. */    printf( "\nCommand-line arguments:\n" );    for( count = 0; count < argc; count++ )        printf( "  argv[%d]   %s\n", count, argv[count] );    /* Display each environment variable. */    printf( "\nEnvironment variables:\n" );    while( *envp != NULL )        printf( "  %s\n", *(envp++) );    return;}

.. is from that website. But it got scrambled, so I copied it and pasted it here. It's cool here.

[VERY LATE edit] Oh now I see it's wrong code.

it might help you all to know I only know C++ not c....and this is written in c (does it matter?) it runs but I dont understand what its opening and where its doing it in the code :/

I'm soooooooooo incredibly sorry for providing the wrong sourcecode. If you still have the need/interest, reply here, I'll get some working code.

// Very basic _execv - example#include <process.h>int main(){   char *args[4];   args[0] = "d2.exe";   // Executable file   args[1] = "windowed"; // Argument 1   args[2] = "1";        // Argument 2   args[3] = NULL;       // Always end with NULL    _execv( "d2.exe", args ); // Executable file, arguments list    /*      -Note that the executable file is passed twice (once as cmd and one as argument).      -The arguments list should end with NULL.      -Try different arguments, if this style doesn't work ("windowed","1" => "windowed 1").    */}

This _should_ work. I haven't found time to compile it yet.

// Very basic _execv - example#include <process.h>#include <fstream>int main(){   char *args[4];   args[0] = "C:'\'Program Files'\'Diablo II'\'Diablo II.exe";   // Executable file   args[1] = "windowed 1"; // Argument 1   args[2] = "windowed 1";        // Argument 2   args[3] = NULL;       // Always end with NULL    _execv( "Diablo II.exe", args ); // Executable file, arguments list    /*      -Note that the executable file is passed twice (once as cmd and one as argument).      -The arguments list should end with NULL.      -Try different arguments, if this style doesn't work ("windowed","1" => "windowed 1").    */}

this is what I have now...ive tried using args 2 and 3 as the following:
1: windowed 1/Normal window/Maximized/Minimized
2: 1,Normal window/windowed 1/Maximized/Minimized/windowed/NULL

Ive also tried giving full and partial paths to the Diablo II.exe directory in both spots :-/

none work....help plz? :)

#include <process.h>#include <fstream>int main(){   char *args[4];   args[0] = "C:\\Program Files\\Diablo II\\Diablo II.exe";   args[1] = "windowed";   args[2] = "1";   args[3] = NULL;    _execv( "C:\\Program Files\\Diablo II\\Diablo II.exe", args );}

Changes:
1) \\ is \ in a char array.
2) I put absolute paths.
3) I used the arguments "" and "windowed" and "1".
