Implement WhatThisHelp?

When I click on the question mark ? on my form, then point to a control, I always get the message:

"HTML Help Author Message"
Cannot open the file "C:\temp\Test.chm

Once I close this message, I get the pop up message "No help topic is associated with this item."

The file Test.chm exist for sure. What is the problem?

By the way, I am using RoboHelp.


Thanks.

Are you sure that robohelp is compiling the file to .chm. Cause Robohelp does not necassary compile it. Also make sure that you associate it to the help. I will try to remember.
