You will have to handle this on your own.

Derive a class from CComboBox, catch WM_CHAR and WM_TIMER messages.

Add CString m_Str; to the class decleration.

Do this:

void LSComboBox::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
   m_Str += CString((TCHAR)nChar);
   SelectString(-1,m_Str);
   //clear the string after 2 seconds
   SetTimer(200,2000,NULL);
}

void LSComboBox::OnTimer(UINT nIDEvent)
{
   if (nIDEvent == 200)
   {
      KillTimer(nIDEvent);
      m_Str.Empty();
   }

   CComboBox::OnTimer(nIDEvent);
}

hello,

i have an mfc CCombobox, which is populated with numeric data. For
example:

2
3
4
5
6
8
10
14
18

i would like to user to be able to type 14 and have 14 selected.
Currently when the user types 1 the box selects 10 and then when they
type the 4, the 4 is selected. I currently have the object type set
to Drop List. If I change to Drop Down, then 14 can be selected as
described, but I dont want the user to be able to enter any numbers
that arent in the list. For example, if they were to try to type 13,
i want it to stay on 10.

any ideas? are there any custom comboboxes that already do this?

thanks.
