Problem launching CHM help file

Roger Seiler · Post by **Roger Seiler** » Wed Apr 09, 2008 1:27 pm

I get a GPF with the following:

#define HH_DISPLAY_INDEX 2

HTMLHelp( oWnd:hWnd, "RMCHART.CHM", HH_DISPLAY_INDEX, 0 )

OR...

HTMLHelp( 0, "RMCHART.CHM", HH_DISPLAY_INDEX, 0 )

I also get a GPF if I include the full path to RMCHART.CHM.

Before getting the GPF, the standard window for displaying a CHM help file is displayed, and then the hated Windows error box is displayed asking if I want to auto-email the GPF error report to MS.

I guess the problem must be some incompatibility with RMCHART.CHM because if I copy Fwfun.chm into the same folder and then substitute "Fwfun.chm" in the function call instead of "Rmchart.chm", then the FiveWin help file displays okay.

However, If I launch Rmchart.chm from outside my app, then it launches okay.

Are some CHM files more equal than others?

Roger,

We don't know if there are different types of CHM.

Next 8.04 version includes automatic support for CHM and HLP files

Same syntax for both types of files.

Antonio,

This method of calling the CHM solved the problem:

Winexec("HH.EXE <myhelpfile.chm>")
