Thread: Dialog ToolTips

Anyone know how to get tooltips to appear when using a dialog?? Here is the code i have so far, but the I can't see the tool tip when it runs. Thanks...

BOOL CHintTestDlg::OnToolTipNotify/*HandleNeededText*/( UINT id, NMHDR * pNMHDR, LRESULT * pResult )
{

UINT nID = pNMHDR->idFrom;
if( pTTT->uFlags & TTF_IDISHWND )
{
nID = ::GetDlgCtrlID( reinterpret_cast<HWND>(nID) );
if( nID == IDC_EDIT2 )
{
CString cstEditText;
m_EditWithToolTip.GetWindowText( cstEditText );
strcpy( pTTT->szText, cstEditText.GetBuffer(cstEditText.GetLength( )) );
}
}

return TRUE;
}

int CHintTestDlg::OnToolHitTest(CPoint point, TOOLINFO * pTI) const
{
return 1;
}

I figured it out... I had to remove the OnToolHitTest function from the code. OnToolHitTest is a method in the CDialog class and by having it in my code it was being called insted of my OnToolTipNotify function.

Thanks all...
