Topic: Preventing Quit and or Document closing.

[GUIDO ROOMS]

I can't find how to prevent AutoCAD from quitting or closing documents.
For the moment I'm using the com event AcadApplication.BeginQuit, which has a Cancel parameter, but I'd like to use the
.net api for doing this.
I've checked arxdoc, but this doesn't make me much wiser.
Thanks in advance for any help on this.

I can't find how to prevent AutoCAD from quitting or closing documents.

The Document.BeginDocumentClose event appears to do this for documents.

From arxmgd.chm:

Implementers can call DocumentBeginCloseEventArgs.Veto() during this notification to stop AutoCAD from shutting down the document.

Also from ArxDoc, about the BeginQuit event:

Wraps the AcEditorReactor.beginQuit() ObjectARX function, which is called when AutoCAD starts to shutdown. The method allows a veto() that will cancel the shutdown.

Problem is, the vetoing, wouldn't know how to do that.
System.EventArgs have no Veto() method. At least, I can't see it. :kewl:

This is from the object browser:

Public Shared Event BeginQuit(sender As Object, e As System.EventArgs)
     Member of Autodesk.AutoCAD.ApplicationServices.Application.

You should be implementing with a DocumentBeginCloseEventArgs like this:

Code: [Select]

private void OnBeginDocumentClose(object sender, DocumentBeginCloseEventArgs args)
        {
            args.Veto();
        }

Thanks MexicanCustard (sorry, that's what you're calling yourself ),

But ah, what about vetoing BeginQuit?
I'd like to prevent AutoCAD quitting without using com events...

But ah, what about vetoing BeginQuit?

That's simply not implemented. As you have already noticed, it would've been necessary to implement a class derived from System.EventArgs to make any additional members accessible. I suppose that's just another stale reference to the original arxref documentation.

Thanks kaefer.
That documentation stinks.
I'll go on using com for this.
