Thread: 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;

}

u have to use windows api for that.

What the heck kind of retarded question is this?

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.

SetConsoleDisplayMode ,,check out msdn for more information on this

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

try including wincon.h;

works just fine on my machine,,compiler dmc, and dont type the code,use copy and paste.

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)
C:\Documents and Settings\msmith\Desktop\binary.cpp:12: error: (Each undeclared identifier is reported only once for each function it appears in.)

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
);

if that wincon points to another wincon inside another folder ,go there.

is there a way to make the screen a higher resolution using SetConsoleDisplayMode()?
