and it change nothing.

can someone could show me a simple example how to add scroll-bar to this member?

Solution 1

Enabling the scroll bars isn't enough. You have to react to the window messages WM_HSCROLLand WM_VSCROLL. Using the GetScrollInfo method you get the position (value) of the scroll bars and then you draw your window content according to this position.

Look up some scroll bar tutorials such as http://www.codeproject.com/KB/dialog/scrolling_support.aspx . In essence, dwo's comment above is what you need to do - handle those messages and set the virtual client area size.
