INFO: CListBox::SelItemRange Selects Only Two or More Items

MORE INFORMATION

• Test for the condition when the first and last items are equal, and in that case, use CListBox::SetSel. -or-
  
  
• Use the windows message LB_SELITEMRANGE. The following code fragment demonstrates how to use this message. The code works when CMyListBox is derived from CListBox.

Sample Code

int CMyListBox::MySelItemRange (BOOL bSelect,
                                int nFirstItem,
                                int nLastItem)
{
   ASSERT_VALID(this);
   return (int)SendMessage(LB_SELITEMRANGE,
                              bSelect,
                              MAKELPARAM(nFirstItem,nLastItem));
}
