How to intercept Ctrl-V or paste command made by mouse context menu?

[m.cicognani]

Hi everybody,

I'd like to intercept the generic paste command inside AutoCAD, and it's easy with the PASTECLIP command using the BeginCommand event... but this method does not intercept the ctrl-v sequence nor the paste issued through the mouse context menu...

If I had a window I could try to override WndProc() and intercept the WM_PASTE message, but I'm inside the plugin windowless class...

Any idea?

Thanks,

Massimo

Hi,

It seems to me CommandWillStart catches the PASTECLIP command.

Try this:

        [CommandMethod("TESTCMD")]
        public static void TestCmd()
        {
            var doc = Application.DocumentManager.MdiActiveDocument;
            doc.CommandWillStart += (_, e) =>
            {
                if (e.GlobalCommandName == "PASTECLIP")
                    Application.ShowAlertDialog(e.GlobalCommandName);
            };
        }

Hi Giles,
yes, indeed, but it doesn't catch the CTRL+V nor, the mouse context menu... as I wrote in the message... 😉

Yes it does, at least from the tests I did (A2014, A2017 and A2019).

Did you try it?

Yes, of course... that's exactly how I intercept the pasteclip command when issued from the ribbon, the Edit menù or typed on the command window, but that event is not fired if I press CTRL+V, although the paste operation is indeed performed... weird...  

Do you intercept the mouse context Paste command too?

Ok, I made other tests and indeed the CTRL-V is translated into a PASTECLIP command, normally.
The difference in my case is that I was trying to intercept the CTRL-V when a table cell is selected. In this case the CTRL-V is translated into a TABLEDIT command, not a PASTECLIP...
