I have many, many external topic links in my project. Is
there any way to automate the testing of these links? Seems like
there must be a less primitive method of testing than just clicking
the links in the output file.
The easiest way that I know of is to generate a WebHelp
project out of it, and run
Xenu on it.
It's free, and works really well. You should have no trouble
finding the corresponding errant links in your Winhelp file.
