Cancelling any running commands

Paulio — Thu, 21 Oct 2010 08:35:39 GMT

I'm trying to figure out essentially how to send a few escape key presses to AutoCAD when I run a procedure in my code to make sure that nothing else is running.

It's ok if I run my command from a palette as I just preceed the command string with ^c^c which is fine. The code I'm running gets kicked off by a button press on a modeless form though so in theory the user could be halfway through doing anything in AutoCAD when they click my button.

I thought about using acedPostCommand as suggested in Kean's blog here:

http://through-the-interface.typepad.com/through_the_interface/2006/08/cancelling_an_a.html

The problem with that is that there are (or seem to be) different entry points for 32 and 64 bit so I don't know how to declare the function so it will work. I need my app to work on either.

So, I thought I'd try Tony T's commandline thing; the problem with that is that I can't seem to figure out how to pass it what I want. I need to pass it chr(27) but can't get it to work. Am I just being thick? (don't answer that)

This must have come up before but I can't find anything or anyone who's done it.

Thanks in advance

Paul

You can check the Document.CommandInProgress()

Here is using COM

                Document doc = Application.DocumentManager.MdiActiveDocument;
                AcadDocument acadDoc = (AcadDocument)doc.AcadDocument;
                acadDoc.SendCommand("\x03\x03");

Thanks for that, but is there any way to do it without COM?

You can trying something like the following:

Autodesk.AutoCAD.Internal.PreviousInput.CommandLineMonitorServices comLineMonServ =
Autodesk.AutoCAD.Internal.PreviousInput.CommandLineMonitorServices.Instance();
foreach (Document doc in AcadApp.DocumentManager)
{
if (doc == AcadApp.DocumentManager.MdiActiveDocument)
continue;

Autodesk.AutoCAD.Internal.PreviousInput.CommandLineMonitor comMon = comLineMonServ.GetCommandLineMonitor(doc);
if(comMon.CurrentCommandName.Length != 0)
doc.SendStringToExecute("\x03\x03", false, true, false);
}

Not sure if it will work on 64bit?, I'm on 32

Thanks cadMeUp but I've already had a go at the sendstringtoexecute too. (sorry should've mentioned that)

The button on my form asks the user to select a block or blocks in the drawing but if I do sendstringtoexecute it seems to get there too late and actually cancels my getselection instead of cancelling whatever's running then doing my getselection.

I need something that's going to run synchronously.

Thanks again for your effort though.
