Hi,
Yes, I did. How do I able to get currently running autocad reference with in my c# application.

You still need COM Interop to access the AcadApplication and
AcadDocument classes.

 

Hi Paul,
I have added references to acax16enu.tlb, axdb16enu.tlb type libraries and I was able to see Autodesk.AutoCAD.Interop assembly. I was able to see AcadDocument interface and class, AcadApplication interface and classes with in help part, So assuming I can create them with in my application. Would you mind explaining a little bit more here. When I was trying with GetObject method, My application is crashing.

Tough to answer without seeing how your doing it...This like should get
you started in C#

using System;
using System.Runtime.InteropServices;
using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.Interop.Common;

namespace WindowsApplication1
{
public class Class1
{
public Class1()
{
AcadApplication acadApp =
(AcadApplication)Marshal.GetActiveObject("AutoCAD.Application");
}
}
}

Using acmgd.dll and acdbmgd.dll will allow you to get the instance your
assembly is running in but the AcadApplication and AcadDocument COM
interfaces are not defined in either of those libraries so you'll still
need the COM interop libraries as shown above.

 

Hi Frank and Paul,
Thank you very much for responding. Yes I have added references for COM interop libraries. am getting following error at statement 'AcadApplication acadApp =(AcadApplication)Marshal.GetActiveObject("AutoCAD.Application");'

Error Inf:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll
Additional information: Invalid class string

Any thoughts.

FYI: I have added references to acmgd.dll, acdbmgd.dll and also In COM tab selected references to AutoCAD 2005 type library, AutoCAD/ObjectDBX Common 16.0 Type Libray.

Regards,
Ramesh

 

The managed Application object has a static property that will return the
COM AcadApplication object.

Autodesk.AutoCAD.Interop.AcadApplication acadApp =
(AcadApplication)Autodesk.AutoCAD.ApplicationServices.Application.AcadApplic
ation;
MessageBox.Show(acadApp.Documents.Count.ToString());

Hi,
am getting following exception if I try to get static property of COM AcadApplication object.

"
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll

Additional information: File or assembly name acmgd, or one of its dependencies, was not found."

Hi Everybody,
I have added COM interop type libraries AutoCAD 2005 Type Library and AutCAD/ObjectDBX Common 16.0 Type Library.

I have imported
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Interop.Common;
using Autodesk.AutoCAD.Interop;
am trying to get reference for embedded AutoCAD application using

private void button1_Click(object sender, System.EventArgs e){
AcadApplication app = (AcadApplication)Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication;
}
Initially I got a compilation error at
static void Main() {
Application.Run(new Form1()); -- here I got error.
}
as ambiguity for Application class, So I have changed it to
static void Main() {
System.Windows.Forms.Application.Run(new Form1());
}

Compilation was fine, when I click the button to get the reference of AutoCAD application am getting following exception at
static void Main() {
System.Windows.Forms.Application.Run(new Form1());
}
The error is :
"An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll
Additional information: File or assembly name acmgd, or one of its dependencies, was not found."

what is the error meaning, why it is saying that it is missing some files.

Ramesh
