Intercept wen use change drawing

[Anonymous]

Hello everyone, I would like to provide to know when a user changes drawing,
would be with keys ALT+TAB or by the menu window. I looked in the reactors
of the application and of the document and I do not find anything good.
There is to you it a way of being able to intercept this event.

Thank you!!

If you are talking ObjectARX .NET API, then look into:

Autodesk.AutoCAD.ApplicationServices.DocumentCollection class' event:

DocumentActivated
DocumentActivationChanged
DocumentBecameCurrent

Most likely, you would handle DocumentBecameCurrent event.

BTW, it is Ctrl+Tab to switch opened drawing inside Acad if multiple
drawings are opened, not Alt+Tab, unless you mean multple sessions of Acad.

No, I don't use ObjectARX.NET, just in VB.net

And lol your right, not ALT+TAB but CTRL+TAB to swith in MDI document 😉

But I would like to have this reactor in VB 😞

So, you use COM interop through Acad's COM Object Model, in which, you may
look at AcadApplication object's Begin/EndOpen, or AcadDocument object's
Activate/Deactivate event, or other events that may provide some help to
your need.

Hello Norman Yuan,I know DocumentCollection have some events like DocumentActivated,but how can I use them,I mean the whole process.For example,I want AutoCAD show a MessageBox when I change the document,what code should I add and where?thanks!!

I assume you are talking .NET API.

I suggest to use DocumentCollection.DocumentBecameCurrent event, instead of
DocumentActivated event, in general.

You hook the event to an event handler at beginning of your app (for
example, if your app implement the IExtensionApplication interface, you put
the code into Initialize() method:

mDwgManager =
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;

mDwgManager.DocumentBecameCurrent += new
DocumentCollectionEventHandler(mDwgManager_DocumentBecameCurrent);

//The event handler

private static void mDwgManager_DocumentBecameCurrent(object sender,
DocumentCollectionEventArgs e)

{

//Assume you have a static Document object "mThisDrawing" declared and
set each time a drawing became current

//Save previous file name

string dwg=mThisDrawing.Name

//Set mThisDrawing to current drawing

mThisDwg =
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

string newdwg=mThisDrawing.Name;

mThisDrawing.Editor.WriteMessage("\nPreviuos drawing->" + dwg + "\nNew
drawing->" + newdwg);

//or if you have reference to System.Windows.Forms

//MessageNox.Show("Previous drawing: " + dwg + "\nNew drawing: " +
newdwg);

}
