    Making Program Launch Full Screen

    How am I able to make the following program (as a school project) launch fullscreen without pressing Alt+Enter efter it has launched

    Code:
    #include <stdio.h>
    
        
    int main()
    {
        while(1)
        printf("10010101101010011010100110010");
    
        return 0;
    
    }

    IIIRC you need to use the windows api call to send key presses to the window (look it up I can't remember what it's called). Is there any real reason to use fullscreen? You really shouldn't unless you need to; I can't think of any reason why.
    Good class architecture is not like a Swiss Army Knife; it should be more like a well balanced throwing knife.

    it is not the most eloquent way to do it ... but here's a way:

    Code:
    	
    keybd_event(VK_MENU, 0, 0, 0);
    keybd_event(VK_RETURN, 0, 0, 0);
    keybd_event(VK_RETURN, 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_MENU, 0, KEYEVENTF_KEYUP, 0);
    This sumulates a virtual keystroke of ALT and ENTER ... include windows.h and put that hunk of code at the start .... I think I have another way of doing it, if I do, i'll post it.

    Where did i put this if it was after main() then it will still run in a small window and not make it full screen.

    Just in case you are wondering this is what it looks like now
    Code:
    #include <stdio.h>
    #include <windows.h>
    
    
      
    int main()
          {
          keybd_event(VK_MENU, 0, 0, 0);
          keybd_event(VK_RETURN, 0, 0, 0);
          keybd_event(VK_RETURN, 0, KEYEVENTF_KEYUP, 0);
          keybd_event(VK_MENU, 0, KEYEVENTF_KEYUP, 0); 
          while(1)
          printf("10010101101010011010100110010");
          return 0;
    
    }

    Code:
    #include <stdio.h>
    #include <windows.h>
    
    void launchfullscreen(void)
    {
        COORD                       coordScreen = { 0, 0 };
       
       
      HANDLE                      hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
        
        SetConsoleDisplayMode(hConsole,1,&coordScreen);
     
    }
    
      
    int main()
          {
          launchfullscreen();
          printf("10010101101010011010100110010");
          return 0;
    
    }
    this should work

    just a few problems with this (within the coding)
    binary.cpp: In function `int main()':
    binary.cpp:9: error: `launchfullscreen' undeclared (first use this function)
    binary.cpp:9: error: (Each undeclared identifier is reported only once for each function it appears in.)
    binary.cpp: In function `void launchfullscreen()':
    binary.cpp:16: error: `void launchfullscreen()' used prior to declaration
    binary.cpp:22: error: `SetConsoleDisplayMode' undeclared (first use this function)

    That is a little beyond my ability to trouble sshoot that at the moment

    that reminds me to read more tutorial

    DEV C++ Still doesn't like line 12 although this has fixed the rest of its moaning

    LOG For the record:

    C:\Documents and Settings\msmith\Desktop\binary.cpp: In function `void launchfullscreen()':
    C:\Documents and Settings\msmith\Desktop\binary.cpp:12: error: `SetConsoleDisplayMode' undeclared (first use this function)

    yeah u have to update your wincon.h file,,,

    so go to include folder search for wincon.h


    scroll through it,,make sure u have the right file,where u see some functions,

    add this :

    WINBASEAPI
    BOOL
    WINAPI
    SetConsoleDisplayMode(
    HANDLE hConsoleOutput,
    DWORD dwFlags,
    PCOORD lpNewScreenBufferDimensions
    );
