Dave,

In the test piece the following code, (forgive my lousy spelling)

Case %WM_COPY
MsgBox "Clipboard functions not alowed",0,"Copy"
FUNCTION = 0
Exit FUNCTION

Case %WM_CUT
MsgBox "Clipboard functions not alowed",0,"Cut"
FUNCTION = 0
Exit FUNCTION

Case %WM_PASTE
MsgBox "Clipboard functions not alowed",0,"Paste"
FUNCTION = 0
Exit FUNCTION

Throws the message away so that it is not processed by the CallWindowProc()
back to the original message handling address. Using the standard key
combinations, my testing here on win95b gives the results that are expected
in that every attempt to Cut, Copy or Paste results in the MsgBox being
displayed showing that the operation is not allowed. I get no response at
all with CTRL + C, CRTL + V, or CTRL + Z, no MsgBox and no clipboard either.

The UNDO capacity from the right click still works as it is not processed
so it all seems to be working correctly here on my win95b version.

Steve,

I cannot seem to activate the following responses when
selecting text in the edit fields and using CTRL + C, CRTL + V,
or CTRL + Z keys. I thought these would have sent the messages
%WM_COPY/CUT/PASTE.

I can activate them by selecting text and then using the right
mouse button to pop up the menu for edit functions.

Case %WM_COPY
MsgBox "Clipboard functions not alowed",0,"Copy"
FUNCTION = 0
Exit FUNCTION

Case %WM_CUT
MsgBox "Clipboard functions not alowed",0,"Cut"
FUNCTION = 0
Exit FUNCTION

Case %WM_PASTE
MsgBox "Clipboard functions not alowed",0,"Paste"
FUNCTION = 0
Exit FUNCTION

I have just posted on my Australian site, a new subclass code
generator for creating control subclasses for API style code.
http://www.pbq.com.au/home/hutch/pbdll50.htm

It will create subclass function for both dialog and window style
API code. This version has most of the commonly used messages as
options that can be selected and when the subclass function is
created, it writes the selected messages into the subclass function.

It comes with a very simple demo and the attached text file has a
simple explanation of how control subclassing works.

Regards and I hope its useful.
