sending keystroke to a program

Hello
I am new to windows programming .
I need your help . I want to start a
windows program and send Y and Q
keystrokes to it to push its buttons .

I am using Dev C++ ver 4.0

Code:

#include <iostream.h>
#include <stdlib.h>
# include<fstream>
# include<string>
# include<conio.h>
# include<time.h>
# include<windows.h>
# include<tchar.h>
 main()
{
    
      system ("start raspppoe") ;
      keybd_event('y', 0, 0, 0);
      keybd_event('y', 0, KEYEVENTF_KEYUP, 0);
      keybd_event('q', 0, 0, 0);
      keybd_event('q', 0, KEYEVENTF_KEYUP, 0);
   
  system("exit") ;

  return ;
}

it is not working ... please help me . Thanks

Use the VkKeyScan or VkKeyScanEx functions to translate the character to a corresponding virtual key code.

Code:

#include<windows.h>

int main(void )
{
	keybd_event(VkKeyScan('y'), 0, 0, 0);
	keybd_event(VkKeyScan('y'), 0, KEYEVENTF_KEYUP, 0);
	keybd_event(VkKeyScan('q'), 0, 0, 0);
	keybd_event(VkKeyScan('q'), 0, KEYEVENTF_KEYUP, 0);

	// or alternatively...
		
	keybd_event(0x59, 0, 0, 0);
	keybd_event(0x59, 0, KEYEVENTF_KEYUP, 0);
	keybd_event(0x51, 0, 0, 0);
	keybd_event(0x51, 0, KEYEVENTF_KEYUP, 0);	
	return 0;
}
