I want create timer in my program so that I can cause it to rerun every minute and I don't know how to do it in a C++ Application. In C# I could just create a timer but I'm struggling here now...
sleep(); is not an option because as far as I know it makes your program inactive for X seconds, I need my app to be active and working, calculating all the time. This is because my code is used to constantly input information into a MS Access table. I was able to create the necessary components of my code to connect and perform the insert/update to the table but this is just on of the many components to the code that I am creating. Please help me with this little (or big?) problem, I'm very new to C++ and learning ATM, but I am developing a fast learning curve. Thanks
Every platform provides api for creating a timer, which will give you a callback usually after timer expires. You can just search for the api available on your platform.
If you are using windows use setTimer function.
I suppose you work on Windows, since you mentioned C#. So take a look at SetTimer , and if it is a MFC app, then look at CWnd::SetTimer .
If you're using C++ .NET, you can use the same Timer class(es) as C#, just use the C++ syntax (using gcnew instead of new, use the ^ for GC references).
Otherwise you could just have a loop:
while (should_keep_looping) {
// do what you need to do
// if necessary:
sleep(1);
}

There is on built in "timer" in C++, and you are correct about the behavior of sleep(). The above thread describes a custom implementation.
