DOC: WM_TIMER Case on Page 94 of Guide to Programming
3.10 WINDOWS kbprg kbdocerr
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) 3.1
Section 4.2.13, page 94, of the Windows SDK "Guide to Programming" manual shows how to add WM_TIMER processing to a window procedure. The code in the book is actually WM_LBUTTONDBLCLK. This is an error.
Chapter 4 of the "Guide to Programming" manual builds a sample program called input. The correct WM_TIMER case is found within INPUT.C, which is in the \GUIDE\INPUT directory of the Windows SDK directory. If this is a Visual C++ installation, INPUT.C will be in the \SAMPLES\INPUT directory.
The correct code is listed below:
case WM_TIMER: wsprintf(TimerText, "WM_TIMER: %d seconds", nTimerCount += 5); InvalidateRect(hWnd, &rectTimer, TRUE); break;
