Hi
I am using MS VC 6.0 and Vista.
I have a dialog box containing a CTabCtrl control.
I put a child dialog box for each tab.
In each child dialog box, I put a number of controls (CEdit...).
For each control, I specify a tooltip.
So far, so good.
Here is my problem:
In Debug mode (not in Release mode), after the tooltip appears, if I
move the mouse so that the cursor enters the tooltip area (before the
tooltip disappears), I get
ASSERT(::IsWindow(m_hWnd));
in wincore.cpp.
It is my understanding that the program is looking for a tooltip for
the tooltip, and that the tooltip is not recognized has a valid
window !
Can someone tell me what I did wrong and how to solve this problem?
Thanks!
Phil
