Modal forms and treeview activeX
I've encountered a problem with the TreeView control relating to modal forms. If I invoke a modal form, from a form that has an activex control, and then a modeless form with a treeview, the NodeClick event (with custom code) does not fire.
Looking through the MSDN CD's I see numerous references to problems relating to using modal forms. I am guessing this is to do with the idea of the AUTOYIELD property. I see that a modal form in Windows is VERY different to a modeless form in terms of message handling. One suggestion which does not directly relate to this problem, involved using a timer and a DoEvents call to try and force a parent form to behave (the example related to a ListView not behaving). I'm trying to see if the concept may apply, but if anyone has any ideas (or a technical explanation) please reply.
Also when using a ListView I can't get the HITTEST method to work correctly. I got a solution for the TreeView using API calls to GETMETRICS but the factors don't seem to relate to the ListView. Any ideas?
