draw in a dialog Image control

[Mark_201]

I have an Image window ( or control?)  in a dialog box.  I know how to get the handle of it but how do I get the rectangle size or coordinates so I can draw lines using LineTo?  Is there an example how to do this?

GetWindowRect ?

GetWindowRect ?

GetWindowRect - gets RECT coordinates relative to screen
GetClientRect    -  gets RECT coordinates relative to the client or itself (i.e.  width and height )

Maybe this is what you need ?

   invoke  GetClientRect,hwnd,addr rcScreen

   And then convert the client-area coordinates to screen coordinates:

   invoke  ClientToScreen,hwnd,addr rcScreen.left
   invoke  ClientToScreen,hwnd,addr rcScreen.right
