Creating Custom Controls in MFC

[Bram van Kampen]

Hi, How do I create a totally new MFC Control type? I take it that I have to create and register a new Window Class, with it's own Message Procedure, and thereafter write my own MFC/CPP around it as a Husk. Is there any way of deriving my own custom controls from CWnd directly and using the message map Macro's? As a new type of control it will need a resource to display it on screen, etc. How do I tie all this together. Regards, :)

Start by reading a few of the many articles at this site on custom controls. You can't expect someone to explain all of that in a few forum posts.

It depends what you want your class to do. Take a look at the Hierarchy Chart | Microsoft Docs[^] and see if there is an existing control that you can derive from (even if it is CWnd), since the base class will provide lots of functionality.

Because all MFC controls are CWnd based you should use that as base class too. Then add the painting (OnPaint, OnEraseBackground), register the window class and add control specific message handlers as necessary. An old but good article by Chris: Creating Custom Controls[^]
