Event Monitor

dbrblg — Fri, 07 Sep 2012 10:28:04 GMT

Bit of a long shot here, but does anyone know of an application or piece of code which monitors AutoCAD and reports when events are triggered?

I'm looking to see when events are triggered in relation to each other and wonder if anyone else has attempted anything like this in the past?

Many thanks

Are you talking about watching events internally to AutoCAD or externally from a systems' standpoint?

Watching events internally to AutoCAD, although if the latter existed i'd have that too

Cool... I just didn't want to mention anything that doesn't apply. You can find some things on it here: http://adndevblog.typepad.com/autocad/

After doing a search I found these specifically:

http://adndevblog.typepad.com/autocad/2012/08/managing-events-at-a-per-document-level.html

http://adndevblog.typepad.com/autocad/2012/05/handling-events-in-vbnet.html

(there was more so who knows there may be something more specific to what you're looking for. Also, I didn't look at these in any great detail so hopefully their accurate).

Here's something I did some time back in a project where I needed to track a few application-level events... specifically window moved and sized events as well as determining whether or not AutoCAD is quiescent before moving on to a specific process. I've modified it so that you can use it to illustrate in your own project (no command is necessary... just netload and try a few things out in AutoCAD).

using Autodesk.AutoCAD.Internal.Reactors;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.EditorInput;

            appEventMgr.ApplicationMainWindowSized += new ApplicationMainWindowSizedEventHandler(appEventMgr_ApplicationMainWindowSized);


            Application.DocumentManager.DocumentBecameCurrent += new DocumentCollectionEventHandler(DocumentManager_DocumentBecameCurrent);

            Application.DocumentManager.DocumentDestroyed += new DocumentDestroyedEventHandler(DocumentManager_DocumentDestroyed);

            Document activeDoc = Application.DocumentManager.MdiActiveDocument;
            activeDoc.Editor.EnteringQuiescentState += new EventHandler(ed_EnteringQuiescentState);
            activeDoc.Editor.LeavingQuiescentState += new EventHandler(ed_LeavingQuiescentState);
            activeDoc.CommandCancelled += new CommandEventHandler(Document_CommandCancelled);
        }

Mgddbg has functionality to print events and some details to command line if you have not looked at that.
