Pause a program - GoFuckYourself.com

"I need to call a function every 1 second in my Windows (GUI) program. I have tried the following:

Code:
#include <windows.h>
...
while (true) {
Sleep(1000);
}This works, except it locks up the application between calls so nothing else can occur.

Does C++ (or the Windows API) have a built-in pause or timer function for this purpose? Thanks."

You need to execute a process message - you need to add a line in the while loop - telling the program to process all new input, so that it won't hang.

I have no idea how to do it in C++, in Delphi I would add: Application.Processmessages; -- I googled it and maybe you should try to add the following in the while loop: Application->ProcessMessages();
