    your question seems vague.
    Are you using any IDEs? (Example: Code::Blocks,Visual Studio,Turbo C,...)
    What compiler are you using?
    How did you try to open the executable file?

    There are several ways for a C program to call an .exe program.

    There are exec...() functions, spawn...() functions, and the system() function. Maybe others too.

    i was looking it up and found:

    system("programname"); // that worked if i put the program in my BIN folder.

    i am using Borland 5.02 compiler.

    when i called the program, another c program i made, it ran in the same dos window the other was currently running in.

    the next thing i wanna know is - how to open this program in a new window dos window

    any ideas?

    Thanks for the replies

    You might want to use a new compiler.

    when i called the program, another c program i made, it ran in the same dos window the other was currently running in.

    In that case you might want to use:
    Code:
    system("start program_name");
    You might also want to use:
    Code:
    system("pause")
    in your called program to prevent the command prompt from closing immediately after execution of the program.

    Anyway,It is NOT recommended to use this method.

    I remember seeing something like this in another thread, so I don't think Batch commands will work with the system() function. You'd need to do something like this:
    Code:
    system( "cmd.exe /c start program.exe" );

    I use a 1987 program called Lets C C Compiler. I now use visual studio, but anyway if your running a DOS program on windows if your program exits as soon as you start it right click and go to program on the tabs and unselect close on exit. then try it if that doesnt work I dont know but its worth a try thats how I get my c programs to run. And to launch it use the command CD and then the location, and then enter the name of you program but I normally navigate to the location useing windows explorer and double click the Icon and it opens up in a command prompt.

    I program using Visual Studio Professional 2008. I have little experience, I'm self taught. I started basic C in early March 2008 with a 1987 compiler and C++ this October with Visual Studio. I normally program in Visual C++ creating form programs. My current project is a simple game where I hide a dot and you have to find it in different random sinerios.

    Try this.

    Code:
    #include <stdlib.h>
     
    int main(){
       system("MyProg.exe");
     
       return 0;
       }
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    Code:
    # include <conio.h>
    # include <stdlib.h>
    # include <stdio.h>
    
    void main ()
    {
    	printf ("Press any key to call the program\n\n");
       getch();
       system ("start prgram.bat");
       system("pause");
       printf ("\n\nPress any key to continue");
       getch();
    }
    this is what i tried for the "start program_name" method - cmd reported that they cant find the file.

    props to you man!!!

    i got the second dos window opened - but it pops up and goes behind the current one.

    what i am tryin to create is a pop up window effects, like "windows" - u choose an option and a new program, window, runs and when its closed it goes back to the original window.

    Thank for the help guys.

    Never use system()
    Use Win32 api.

    Download GCC, which for windows you find as MinGW. Or download Visual Studio, which is a debugger/IDE/compiler all together.

    You can create a "normal" window, not a shell with CreateWindow() or CreateWindowEX() functions using the win api. Google it.

    But all depends on what you want to do with the new windows. If you want to pop up messages then win api is really what you want. If you indeed want a new shell then system(), spawn() etc etc is a quick solution

    Which would mean that the application won't be portable.

    But then again, most of the things you'd do in system() wouldn't be portable anyways, unless you have a bunch of #ifdefs for different platforms that create the string that you pass to system()...
