CListCtrl transparent
in [MFC]
|
From: AliR (VC++ MVP) on 29 Aug 2007 01:32 Its going to be very difficult to accomplish because of the way the list control scrolls. Here is an example of what I had to go through to make a listbox transparent: http://www.codeproject.com/combobox/TransListBox.asp AliR.

From: Tom Serface on 29 Aug 2007 10:54 I wanted to do something similar where I put a bitmap on the back of a list control when it didn't have any items in it and I just used a big bitmap button that I show or hide depending on the number of items in the list control (0 or more). You might find this to be an interesting approach, although I'm not a big fan of busy backgrounds like this article illustrates: http://www.czvc.com/tech/MFC%20Programmer's%20SourceBook/listview/background_image.shtml.htm Tom "Scott Kraemer" <skraemer8(a)cox.net> wrote in message news:%23qss7Sf6HHA.536(a)TK2MSFTNGP06.phx.gbl... > Anyone have a example of how to make a CListCtrl Transparent?
