BUG? MarkupStackPanel Internal Application Error

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I've found a strange bug that seems to appear intermittently when debugging the MarkupLabel control. When I use a StackPanel object with more than one child and the MouseEnter and MouseLeave events pointing to the same handler sub, the IDE will raise an "Internal Application Error" when entering debug mode at a breakpoint within the handler sub.

I think this is happening because the MouseLeave event is firing when the IDE enters debug mode and the MarkupControl is trying to execute code in the form (but can't because it is in debug mode).

Here's a test project:

Put a breakpoint in the MouseEvent sub and run the project. Move the mouse over the text and you *may* see the error message, if not, move the mouse and press F5 to resume execution then try again. Eventually you should see the error message.

	Hi Jason, You will get that error but only when mouse is entering MarkupLabel from the bottom Is very strange and I tried several times and I didn't get an error when mouse would enter from left,top and right Maybe it will help CJ to find this.

	Hi, yes, guess VB related thing - Markup send "Leave" notification while you debug "Enter"

	Hi Aaron...thanks for testing this and my other recent posts. That has to be one of the strangest bugs I've seen in a while (in that it only manifests itself when entering the area from the bottom edge). So Oleg, while it may be a VB related thing, why does it only happen when you enter from the bottom?
