Blank thesaurus dialog - Thesaurus Desktop .NET - Forum

I have a thesaurus control on a form and use it with TXTextControl 15.1. It is called from my code like this:

this.thesaurus1.DialogForm.StartPosition = FormStartPosition.CenterParent;
this.thesaurus1.DialogForm.Visible = true;
this.thesaurus1.DialogForm.TopMost = true;
this.thesaurus1.Show();

The first time it is called the dialog is empty (just showing the grey background). All further calls work as expected. Any ideas what could be causing this?

Thanks,
Wolfgang

Thank you for your suggestion, Jim - quick as always!

But I wouldn't have thought it could possibly make a difference (and it didn't) because if the DialogForm didn't have a ThesaurusControl assigned to begin with how would it have worked perfectly every time except for the very first call?

I replaced the call to Show() with a call to ShowDialog() and am now running into this exception:

System.ArgumentOutOfRangeException: StartIndex cannot be less than zero.

This happens after right-clicking a word in TXTextControl and selecting the menu entry thesaurus which calls your dialog as described before.

Sorry for the delay but I've been working hard with the TXTextControl people to reproduce a bug in their control. I have to say that the so-called "integration" of RapidSpell in TXTextControl is a nightmare (not that I feel entitled to any fingerpointing; I don't know who's "fault" it is and I make too many dumb mistakes myself to feel like blaming anybody...).

What makes me not-amused is that I had no problems with RapidSpell until I bought the "integrated" version. That additonal money spent (not to mention literally weeks of bug-hunting) obviously entitled me to become part of the TXTextControl QA department. Enough ranting... I have to say that their support is very quick and they give the impression that they take the problem seriously. So there is hope - but until the (serious) problems of the RapidSpell integration are fixed, I would advise anyone to hold back on an intended purchase of RapdiSpell from TXTextControl.

NOTE: This critique does not apply to the Keyoti RapidSpell component as such. As I said, I've had no problems with it; the support is very fast and you don't need the "integrated" version to use TXTextControl and RapidSpell in combination. I hope this post spares some people a lot of frustration.

OK, now I'll try to reproduce the thesaurus problem in simple project.

Thanks for your thoughts Wolgang - sorry I'm unsure what differences you found (between the integrated and our version), but there's been a major overhaul for TX16 that may or may not (since I dont know what the problems were for you) be better for you. Or just stick with the unintegrated version of course...

Please do could send via http://wikisend.com or email to me via support @ keyoti.com


Thanks
Jim

Thank you Jim,

Your advice did it - at least for the demo project and I have no reason to assume it won't work in the real project but need time to try it out. Please consider this case closed unless I come back ;-)
