Check Instances of AutoCad for Open Documents

[beerboy]

What I am trying to do is check all the instances of Autocad that are running and check for all of the open documents in each one. I have this working in VB6 but .NET is giving me problems. I can get the MainWindowTitle but the other documents open for that instance I have not been able to figure out. Sorry if this has been posted before but I am not sure if I am even on the right track. Any suggestions for this in .NET? I would prefer not to use GetObject(, "Autocad.Application"). Thanks Everybody

Just out of curiosity, why don't you want to use the getobject method?

Because it does not want to work, I was looking for other options, I wanted to move out of the VB6 era. I am using VS2008 so I may not have any other options. I am trying to find out. Thanks again.

FWIW -

You may find this old post useful as an example of how to get an existing instance, or create a new instance of an application:

Sounds like you need to check for an active process, prior to creating a new instance.

Here's a VB.NET snippet from one of my projects, for you to pull from:

Imports Excel = Microsoft.Office.Interop.Excel
Imports Microsoft.Office.Interop

Imports System.Diagnostics
Imports System.IO

Module FOO

    Sub Excel_Foo()

        Dim xlApp As Excel.Application

        Try
            ' Look for an existing process, if available getObject
            If Process.GetProcessesByName("Excel").Length > 0 Then
                xlApp = CType(GetObject(, "Excel.Application"), Excel.Application)
            ' Else createObject
            Else
                xlApp = New Excel.Application
            End If

            ' <-- Do something

        Catch ex As Exception

        Finally
            xlApp = Nothing

    End Sub

End Module

It is the Do Something I am trying to figure out.
This returns the MainWindowTitle
AutoCAD Map 3D 2010 - [Drawing1.dwg] First instance
AutoCAD Map 3D 2010 - [A5119.DWG] Second Instance
If I have multiple files open in each instance I want the WindowTitle for each one.

Dim p() As Process = Process.GetProcessesByName("Acad")
ForEach proc As Process In p
Debug.Print(proc.MainWindowTitle)
For Each AcadDocument in proc...?
Next

Iterate through each instance and each document and return the window title.

Instead, why not simply iterate the Documents Collection for each instance of AutoCAD?

Perhaps this will be helpful: Control the Drawing Windows

[beerboy]

That is what I am trying to do.

One step further...

Iterate through a Collection Object

[beerboy]

What if none of these will import?
'Imports Autodesk.AutoCAD.Runtime
'Imports Autodesk.AutoCAD.ApplicationServices
'Imports Autodesk.AutoCAD.DatabaseServices
'Imports Autodesk.AutoCAD.EditorInput

Then you're missing Assembly Reference(s).

... In Solution Explorer, Select the 'Show All Files' button, and expand the References node... Within, you should have AcDbMgd.dll, and AcMgd.dll added (be sure they both have 'Copy Local' = False in the Properties window).

If you do not know what these Assembly References are, see this thread.
