Launching a CHM from Winhelp.

I have used Winhelp 4 for context sensitive help in our application (as it supports bullets, formatting, links, etc. etc.). However, when I link to a topic in the main reference manual (for which I used HTMLHelp) nothing much is happening. The format of the link is for example,

More information blah blah blah can be found hereJumpHtml('mk:@MSITStore:ISIS.chm::/General_Concepts/Miscellaneous.htm')

This was formed by creating a jump to an external topic from within the help system.However, this is not working (I simply get the 1024 message regarding problem with the help file) - the .HLP file and the .CHM file are in same directory on the local drive.

As a secondary point : clearly the CHM file needs to be launched from the application. Is there a resource available or can someone help with an explanation of how to launch an HTML help file on a network drive without Windows objecting.

Thanks,
Iain.

Iain,

I believe you need to use the ExecFile macro ("EF" for short) to do this. Either of the following forms should work:

EF(`hh.exe',`ms-its:helpfile.chm::/topic.htm',1)
EF(hh.exe,ms-its:helpfile.chm::/topic.htm)

where "hh.exe" is the executable used to open .chm files, and "ms-its:helpfile.chm::/topic.htm" specifies the required help file and topic.

Thanks Peter - that solves problem 2.

Totally tearing my hair out now with the first issue. That is, a link in a Winhelp popup (context sensitive message) cannot launch a topic in a CHM file (I'm using Insert - Help Jump - external topic). I can see the topics in the CHM file from within my project and I can create the link without any problems - it simply doesn't work when I click the link from the popup :-(

I can create an identical link from the main window (rather than a popup window) and clicking on that link will launch the CHM topic inside the main window.

I wonder therefore if this has something to do with the Window hosting the topic, although I can see no way to specify a different window when I create the external topic.

Anybody ??

Iain.
