Opening Drawings Using VB.Net

[dhorger]

Hi folks,

I'm trying to open a list of drawings to perform operations on each one, but I've run into a snag. Here's the relevant code:

Dim dm As DocumentCollection = Application.DocumentManager
Dim doc As Autodesk.AutoCAD.ApplicationServices.Document

For x = 0 To lstFiles.Items.Count - 1

' open the drawing
doc = dm.Open(lstFiles.Items(x), ro)

' set the drawing current
dm.MdiActiveDocument = doc

' do stuff...

' close the drawing
doc.CloseAndDiscard()

Next

Here's the snag: when I try to make the most recently opened item the current drawing (using the line in bold), processing of the code stops until I manually set the focus back to the document that was open when I started the function. Once I do that, processing again starts at the next line of code. No errors pop up. What's the proper way to do this so that I can have the drawing that was just opened the current drawing?

Thanks,
Dave Horger

Hi Dave,

You've posted this to the VBA newsgroup.

You are far more likely to find expertise to resolve your problem in the
.NET newsgroup.

You're using the .NET API so the .NET newsgroup is a better place to post.
Repost there rather than reply to this.

If your code is called from a command method, then you need to add the
CommandFlags.Session flag to the CommandMethod attribute.

Thanks! That did the trick.

And I'll remember to post in the .Net newsgroup, next time.

Dave,
I don't know where do you put this?
What did you have to put in?

Thanks,
