Hi,

Since upgrading to 18.4.0 I have been having random crashes in my existing VB6 program when attempting to display a dialog using the TaskDialog.

When the program crashes in goes straight to desktop and if it is running from within the VB6 IDE it takes out VB as well. None of VB's error trapping would catch it so it took a lot of effort to narrow down the problem.

Eventually I managed to find the issue and then reproduce it one of your samples.

Steps to reproduce:

1. Load the sample project from <Codejock root>\Samples\Controls\VB\VistaTaskDialog

2. Find "cmdShowDialog_Click"

3. Add the line "taskDialog.EnableMarkup = True" somewhere after the reset

4. Run the program

5. Click "Show Dialog" a number of times with various options to verify working as expected

6. Edit the text for "Footer" to consist only of a hyperlink e.g. "<A HREF="executablestring 2">Hyperlink Text</A>"

7. Click "Show Dialog" and close it a few times until the program crashes - this is random between 1 and 10 times usually but I have had 20 times once.

Adding any non-whitespace before or after the link stops the crashing.

Hello Kenton,

What previous version of Codejock ActiveX you used before 18.4, which worked without errors?

Hi Artem,

I have now downloaded 18.5.0 and the problem is still there.

I have uninstalled all other versions to be certain and followed the steps in my OP and it still crashes. :-(

Perhaps it matters where I add the "taskDialog.EnableMarkup = True"? I am adding it as the line after "taskDialog.Reset" so it is the second line in the Sub.

Regards,

Kenton
