In many windows such as Device-Manager and Regedit, we see a vertical separator that divides two white child windows. These separators can be dragged side to side using the mouse.
Is there a windows control or native common control that can be used to create this effect?
I couldn't find anything on MSDN, and spent all last weekend trying to emulate the behavior using various combinations of child windows and custom resize-handling.
I'm specifically asking in regard to the C API, IE CreateWindowEx(), etc.
Thanks
