addhandler cancel command

[Anonymous]

I am trying to add a handler for cancelling a command.

On http://help.autodesk.com/view/ACD/2015/ENU/?guid=GUID-F432E285-8B94-4ACD-A186-89E1218DEC07 i can see that a cancel handler exists but my interop.acadApplication doesnt have a cancel event.

"Addhandler AcadAPP.EndCommand, AdressOf..." and "Addhandler AcadAPP.EndCommand, AdressOf..." are working for me but i need to add a handler for cancelling a command too.

Does anyone know how to do this?

You can add Handlers handling those events, but they will not Issue those events, i.e. you have to Cancel the Command you're self.

doc.CommandCancelled +=doc_CommandCancelled;
doc.CommandFailed +=doc_CommandFailed;

I see now that my post wasen't really clear.

I only need to handle the event but i don't know how to write it in vb.

AddHandler AcadAPP.EndCommand, AdressOf callback_EndCommand works for me.

The problem is that AcadAPP (Autodesk.Autocad.interop.Acadapplication) doesnt include any cancelcommand handlers.

Do you know how to write your piece of code in vb?

Hi,

The issue isn't related to the VB language, it's related to the used API.

AutoCAD COM API doesn't provide a CommandCancelled event,  the AutoCAD .NET API does provide it for the Autodesk.AutoCAD.ApplicationServices.Document class.

Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument

AddHandler acDoc.CommandCancelled, AddressOf docCommandCancelled
