Microsoft Visual C & C++: still with the tooltips *sigh*

• kallareka / 202 / Tues, 09 Feb 2010 18:57:00 GMT / Comments (2)
• I have a dialog in which i create buttons dynamically, i have derived my own class called CBokningsButton from CButton... here's the problem, i get an assertion error when i try to do: m_tooltip.AddTool(GetDlgItem(9001 ,"hey"));
  the assertion error is: ASSERT(::IsWindow(m_hWnd));
  
  the wierd part (or the part I find wierd) is that i can do this if i double create the buttons. it hard for me to explain exactly how i mean but ill try:
  
  When i run the prog it creates some buttons then if the user change some stuff it deletes the buttons and create new ones. each button represents a different time in a day, depending on which day the users select the buttons can have a different layout depending in the information i get from a mysql database.
  So before i create buttons i delete the old ones like this:
  
  CBokningsButton* ptrButton;
  for(int t=0;t<200;t++)
  {
  if( (ptrButton = (CBokningsButton*)GetDlgItem(9001+t)) != NULL)
  {
  // button exists
  ptrButton->DestroyWindow();
  }
  }
  
  now i know this i like the worst solution ever to delete buttons but never mind that now, the thing is that if i replace the DestroyWindow() line with my AddTool line i get the tooltips to work the second time i create the buttons (rember that now the old ones hasnt been deleted so the new are just printed on top of the old ones).
  If i try to do the AddTool any place else in the program i get the assertion error...
  
  i thought it to be most logical to do AddTool at the same time i create the button but that gives me the same error
  
  does anyone know what im talking about and if so can you help me?
  
  thanx
