Using html help files

[RLD]

When I use an html file for the "Help for this VI" menu item it works fine in the LV 6.1 development environment. But when the VI is converted to an EXE there is no response to clicking "Help for this VI".

The help function works as expected when *.hlp type help files are use. Is there restriction on html type help files in LV 6.1?

Try the following. When you compile your VI into an executable, the path from the caller VI to the help file change. Let say that you call your help file using your VI path as a reference and that the help file is in the same directory as your VI. Then, you may be calling your help file as "..\helpfile.hpl". When you compile your VI into an executable, think as it as your VI is now "inside" the executable. Therefore your new calling path should be "..\..\helpfile.hpl".

It doesn't make any difference if the Help Path field is assigned to "{helpdir}:\helpfile.htm" or "helpfile.htm", when the EXE is created the "Help for this VI" menu item is "ungreyed" but the browser window does not open when Help for this VI is selected. (Note, I substituted curly braces for the pointy brackets around helpdir to avoid the html restriction of this forum.)

Yes, using "..\helpfile.htm" solves the old LLB help path problem, but an EXE of the LLB still doesn't display the help file. In all cases *.hlp type help files work just fine.

I was able to reproduce this issue in LabVIEW 6.1, however it has been fixed in later versions of LabVIEW. A corrective action report has been filed for this issue. The workaround for version 6.1 is to use ActiveX controls to open an Internet Explorer Browser and an invoke node to navigate to the correct URL (see solution.zip).

Jen,

I think I know what the Active-X solution would look like. But your zip file is empty! (Maybe the solution is simplier that I thought ;=}.)

Rich,

It was empty wasn't it! Let's try this again.
