Patch reliability is unclear. Unless you have an immediate, pressing need to install a specific patch, don't do it. |
Hi again,
I re-read my post and still think I wasn’t accurate. Sorry. That’s what I get for hurrying.
You shouldn’t need an include file at all. *I* needed one to compile my help file — it assigned topic ID for reference in VB/VBA. I assume RoboHelp automatically or interactively assigns topic IDs.
Anyway, Click here to visit Paul O’Rear’s site that was so helpful to me.
I used parts of his HelpAPI.bas file (a link is near the bottom of the page) to call HTML help from my VBA forms. I used a combo of WinHelp pop-ups (supports graphics) and HTMLHelp (when presenting the entire Help file). I’ve been using a very competent program called HelpScribble which lets me compile both *.hlp and *.chm from the same source.
My forms are coded to look to the *.hlp file to display “What’s This?” help and command buttons call the *.chm file using HelpAPI. The code in your post looks a lot like the WinAPI calls, so there may be something to learn there.
You mentioned “some RH add-ins to VB” and I’m assuming those were “references” to the RH *.dll. Bear in mind that using RH’s library means you will probably need install it on every pc running your help.
To test it, do this: In the VB project, create a module and put the Public declaration in that.
In the form, tie the command with an event of some kind (like clicking a command button). I believe the second parameter in the statement ought to be me.HWND which provides the Windows “handle” for the VB form (“me”).
Now run the form and click the button to see if this displays the help you want.
If it still doesn’t, perhaps you can post some of your code (all sanitized) so we can scrutinize further?
If it does work, then all we need to do is figure out how to make it appear in a pop-up.

Mr Bob, Mr Bob!
I’ve got it now. The thing that was keeping us from creating an object was that the public declaration:
Public cshObject As New RoboHelp_CSH
…needs to be in a module, not the class module. Add a module to your project, and put this code in the module. Remove it from the class module.
Now save and run your project, and click on the one control to which you’ve added a click event — the help file should appear.
Now, about creating a way to get help when you want it rather than having it pop up every time you click in a field, there’s some info out there.
See, for example, Shadow Mountain Tech’s articles on programming context sensitive help.
According to RoboHelp (yes, I installed the trial version to check!), What’s This Help (using the question mark) from an HTML help file is not available to VB programs — only C++ and C#. Further, it is text-only What’s This? help. If you want to use What’s This help for a VB Project, you must create a WinHelp file.
I hope this helps — it certainly answers your initial question about why you were getting the error message about the object!

Kim,
Setting up a module really helped. Also, I was able to get F1 field help using this new module and the Don Lammers article on HTML/Visual Basic in the Shadow Mountain web site that you recommended. Interestingly, RoboHelp recommended the class module that originally had the public declaration.
That was the main obstacle to setting up a demo of the system–now I don’t have to think about this 24 hours a day. Thanks for taking such a strong interest in my project.
