CEvent MFC class. CEvent::ResetEvent() puts a thread function into sleep state and CEvent::SetEvent() wakes up function.
CEvent::PulseEvent() sets event to avalable and then unavailable.

Microsoft documentation:

mmmm..I saw documentation but it isn't very clear, so in setEvent I can put keyDown event like event that wakes program? Help

keyDown in MFC is CWnd::OnKeyDown() of WM_KEYDOWN message handler. Put your SetEvent call into that message handler

How must I do? Can I see an example?
Yes, you definitely want to avoid calling Sleep because there is nothing I am aware of that will stop it - it can not be interrupted.

You are better off waiting for an event using the CEvent class as mentioned. You can then call WaitForSingleObject or WaitForMultipleObjects and let it handle the "sleeping" for you.

steveb's comment above had the hint for you. To use WaitForSingleObject you must pass it an object to wait for. That can be any 'handle' object that can be signalled. In your case, you need to declare an event object (CEvent or similar) accessible to the class that receives the keyboard messages and set the event when a key is pressed.

for (int i = 0; i <= 20; i++)

WaitForSingleObject(OnKeyDown, 100);
