Load AutoCAD from VB.Net (Newbie)

Anonymous — Sun, 18 Sep 2005 23:01:59 GMT

Can someone help me to:

1. Connect to AutoCAD 2004 or higher using VB.Net
2. Open AutoCAD if not open already
3. Open a drawing if AutoCAD is already open.

All help will be greatly appreciated.

Cujo

PS - presume I am starting with only a drawing name so if there are imports, etc. I'll need those as well.

Thanks!!!!!

I'm very new to VB.net too, but play with it
occasionally. Here is a way to open a cad dwg, then renaming it. The
form has two buttons on it, one labeled to start and one to save
as.

Inherits
System.Windows.Forms.Form

Region " Windows Form
Designer generated code "

Public
color=#0000ff size=2>Sub
size=2>New()

MyBase.New()

'This call is required by the Windows Form
Designer.

InitializeComponent()

'Add any initialization after the
InitializeComponent() call

End
color=#0000ff size=2>Sub

'Form overrides dispose to clean up the
component list.

Protected
color=#0000ff size=2>Overloads
size=2>Overrides

If disposing
Then

If

size=2>Then

components.Dispose()

End

I noticed I let some of the trash in my code, sorry
about that, you can get rid of some of the comments and anything to do with
stream. It was just some stuff I was playing with. Also, you
must add in the autocad reference. Depending on what you want to do with
your dwgs, add the respective references. Below is the same thing cleaned
up.

well.
