clicking in full screen mode

how do you make the mouse click while a full screen program is open?

Code:

#include <windows.h>
#include <conio.h>

int main()
{
    keybd_event(VK_MENU,
                0x38,
                0,
                0);
    keybd_event(VK_TAB,
                0x09,
                0,
                0);
    keybd_event(VK_TAB,
                0x09,
                KEYEVENTF_KEYUP,
                0);
    keybd_event(VK_MENU,
                0x38,
                KEYEVENTF_KEYUP,
                0);
    while (!kbhit())
    {
          mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
          Sleep(1);
          mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
          Sleep(1);
    }
}

i read adrianxw's tutorial and this the the best i can do, it alt+tebs to the full screen program but then it doesnt click

Trying to write a hack for a 3D game?

I doubt anything will work short of modifying a game DLL to wait for IPC communications and then execute some DirectX call or another as directed.

@mods: Don't ban me yet. I'm speaking completely hypothetically, and the OP wouldn't know what I was talking about anyway, if I wasn't; and if they did, they wouldn't know what to do about it.

This does seem kind of dodgy doesn't it?
