    Problems entering Fullscreen

    hi every one, i was trying to enter fullscreen with my console app
    but for some reason it doesnt work correctly.When i launch the
    Program it enters fullscreen for about 1 frame and then gets back
    to windowed mode,i have tryed nearly everything now SetConsoleDisplayMode,
    ALT-ENTER and even inline asm (yeah i know it wouldnt work on win32 compiler
    :P )
    im working with devcpp 4.9.9.2 and here is the code im using
    btw is there a chance to sync the screen clearing????


    Code:
    #include <windows.h> 
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    
    
    
    
    typedef enum {false, true}	boolean;
    
    DWORD n;
    DWORD size;
    COORD coord = {0};
    
    HANDLE h;
    WORD wOldColorAttrs;
    CONSOLE_SCREEN_BUFFER_INFO csbiInfo; 
    
    
    void renderscreen(void)
    {
    
      
      
      
      
      while(1)
      {
              printf("test");
    
              
              GetConsoleScreenBufferInfo(h, &csbiInfo);
      
              wOldColorAttrs = csbiInfo.wAttributes; 
              size = csbiInfo.dwSize.X * csbiInfo.dwSize.Y;
              SetConsoleTextAttribute ( h, FOREGROUND_RED | FOREGROUND_INTENSITY );
    
              
              FillConsoleOutputCharacter ( h, TEXT ( ' ' ), size, coord, &n );
              GetConsoleScreenBufferInfo ( h, &csbiInfo );
              FillConsoleOutputAttribute ( h, csbiInfo.wAttributes, size, coord, &n );
              SetConsoleCursorPosition ( h, coord );
      
      }
      SetConsoleTextAttribute ( h, wOldColorAttrs);
        
    
    }
    
    int main(int argc, char *argv[])
    {
      keybd_event(VK_MENU,0x38,0,0);
      keybd_event(VK_RETURN,0x1c,0,0);
      keybd_event(VK_RETURN,0x1c,KEYEVENTF_KEYUP,0);
      keybd_event(VK_MENU,0x38,KEYEVENTF_KEYUP,0);
      
      h =  GetStdHandle ( STD_OUTPUT_HANDLE );
      
      renderscreen();
      return 0;
    }

    You can avoid sending the keyboard events by calling the SetConsoleDisplayMode() function instead.

    However, you also have to have a screen setting that actually corresponds to a VESA text mode, or you won't be able to enter full-screen mode.

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    ok i figured out that the problem was the
    visual designs (i deactivated them and everything worked)
    is there a way to deactivate them (maybe a compiler option)
    cuz i think the users wont like to do it themself

    What do you mean by "visual designs"? Almost everything you can do from the console settings menu can be done via console functions.

    Yes, I guess that there are other options/settings that may prevent full-screen mode.

    Disabling your visual themes isn't the answer to making your console app show full screen.

    The answer is that you have to have a large enough visual buffer to handle the full screen. It doesn't matter what other settings you give it, without enough visual buffer, you won't get full screen console window in WindowsXP.

    Your console app's properties should show 80 by 25 (or whatever lines you are using) as your applications window and screen buffer size, under the tab "layout". It should have "full screen" selected. Windows XP will automatically set these settings for your app, regardless of what you set them to, so don't waste your time.

    You console windows properties (not your applications console window properties), may show either full screen or window selected, but it needs to have about 140 by 100 as the first and second entry in "layout", for it's screen buffers. The exact amount depend upon your visual themes, etc.

    I went round and around with a console app that wouldn't go full screen (and needed to), and finally stumbled upon this setting. (I kept changing the applications console settings). As soon as I changed that screen buffer setting to a larger figure, it has been good ever since. (I had to re-start the app to see the change each time I changed it, of course). Why all this run around? Because I had just changed my visual themes to show a pic in the center of the desktop, and it needed to have more visual buffers than I was giving it, now.

    Don't know if that will help you, but it was my answer for sure.

    Good luck!
