Tooltip causes an ASSERT() in a child dialog box - Visual Studio
Tooltip causes an ASSERT() in a child dialog box
Hello experts,
I already posted about my problem a couple of days ago, but it's not
solved yet and I have some more details about it.
Using MS VC 6.0 and Vista.
I create a CTabCtrl control in a dialog box. For each tab, a child
dialog box contains a bunch of controls (CEdit, CComboBox...). I can
display tooltips for each control, no problem.
The problem is that when the cursor (I mean the mouse) leaves a
control, if it enters the tooltip area, I get an ASSERT() warning:
In WinCore.cpp
void CWnd::AssertValid() const
{
...
// should be a normal window
ASSERT(::IsWindow(m_hWnd));
...
}
This occurs only when the dialog boxes displayed in the tabs are CHILD
dialog boxes. If I choose "Overlapped" or "Popup", it works (but I
need a child dialog box).
What should I do to avoid this problem?
TXS
Phil
