Best class to specialise

What is the best class for me to choose to subclass from: 

I want to create a 'graph' window which displays data derived elsewhere in my application. This window will be the only thing inside an instance of a CXTPDockingPane and the majority of work in the class is in the OnPaint or OnDraw method. I have tried deriving from CDialog, CDialogBar, CXTResizeDialog and none of them seem to update the screen properly when I resize the pane - the screen simply doesn't change... I have placed breakpoints in the code, they all hit the OnPaint/OnDraw methods, and the code calculates the coordinates correctly and looks like it is redrawing my graph properly, but the screen never updates - I have to move another window (another application) over mine and away again to see the new drawing. What am I missing / doing wrong??

	Hello, in your window class catch WM_SIZE and call Invalidate(FALSE)
