Title: Calling Help files from masm32
Post by: Ron_Co on March 19, 2009, 05:33:54 AM
I have created a win32 program in masm32 and I have created a Help file for this program. How do I call this help file from inside my program?

What type of help file ? There are currently 3 help systems for Windows, .hlp (WinHelp), .CHM (HTML Help 1.x) and .Hx (HTML Help2). All have specific APIs to use them..

For CHM files look here:

For Help2 files check out the GoAsm forum here:

If it is a standard help file that runs when you double click on it, the simple answer is just execute it using WinExec.

For *.hlp, use this:

Code Select
invoke WinHelp, hWin, chr$("MyHelpFile.hlp"), HELP_PARTIALKEY, chr$("FindThisWord")

Before closing your program, close Help like this:

Code Select
invoke WinHelp, 0, 0, HELP_QUIT, 0
invoke DestroyWindow, hWin ; destroy main window and all its children
