I had a query about Read-Only Edit windows.

Many thanks to all who sent me suggestions on how to implement them.

Following up on some of them, I have found one solution to the problem:

i)	Subclass the edit window (using SetWindowLong, GetWindowLong and 
CallWindowProc to insert your window procedure before the default one)

ii)	Trap WM_SETFOCUS messages and return 0 from them (refusing the change
focus request). This prevents any keyboard input from going to the
window

iii)	Trap WM_SETCUSOR messages to prevent the Caret cursor being drawn.
Make sure you set the cursor to some appropriate one otherwise you'll
inherit the last cursor used (e.g. a double-headed scrollbar cursor).

These measures work fine. They also allow you to switch the read-only
feature on and off - by testing a boolean condition in the 
setfocus and setcursor routines.

Many thanks,


Simon Whiteside.
