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

m.cicognani — Wed, 02 Jan 2019 11:02:21 GMT

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...
