How do I fix this problem in C++?

I need to know how to properly use the SetTimer() function in C++ from windows.h.. Please helm me about this... I have this code, but it doesn't seem to have any result...





#include %26lt;windows.h%26gt;


#include %26lt;iostream%26gt;


#include %26lt;conio.h%26gt;





using namespace std;





HANDLE curhndl();





int i = 0;


void proc();





main()


{


void (*fptr)() = %26amp;proc;


SetTimer((HWND)curhndl(), 1, 1, fptr());


getch();


cout%26lt;%26lt;i;


getch();


}





void proc()


{


i++;


}





HANDLE curhndl()


{


static bool called;


static HANDLE hwnd;


if (called != true){


hwnd = GetStdHandle(STD_OUTPUT_HANDLE);


if (hwnd == INVALID_HANDLE_VALUE){ return INVALID_HANDLE_VALUE; }


called = true; }


return hwnd;


}

How do I fix this problem in C++?
I think there may be a few problems with the code. One that jumps out at me is in HANDLE curhndl().





You are not initializing 'static bool called', so it starts off as a garbage value (not 0). Since 'true' means 'not-zero', called will likely always be true. That means GetStdHandle never executes.





Hope that helps. Good luck!
Reply:Sorry to say, but your code is ABSOLUTELY incorrect. Sorry again :(





If you want to use API timers, you should spin message loop. The handle (that you pass to SetTimer) should be not the standard output or whatever, but a handle of a real window (that is why it is of HWND type)! If you pass to SetTimer something different from a window handle (even if you cast it to HWND as you smartly did :) ), the function will fail and will not create a timer.





I don't think it is a good idea to use API timers in console application at all - they are not designed to work this way. Try windowed application.
