Stand alone applications

[rajpaul75]

I have a standalone application in .net .Give me some ideas how to connect the autocad as my standalone application needs "select a point" and i am looking to select the current cad layout not a new instance.

Thanks for your help

COM Interop. Check out
System.Runtime.InteropServices.Marshal.GetActiveObject, although I haven't a
clue how to find a specific instance if multiple instances of acad are
running.

You can't choose which instance of Autocad you want to connect to.
COM will connect to the first instance available.

The sample below is for 2009

{code}
Public acadApp As Autodesk.AutoCAD.Interop.AcadApplication

Public Sub getOdbx(ByRef acadApp As Autodesk.AutoCAD.Interop.AcadApplication, ByRef acadDBX As Object, ByVal FileName As String)

Try
acadDBX = acadApp.GetInterfaceObject("ObjectDBX.AxDbDocument.17")
Catch ex As Exception
Try
If Not acadApp Is Nothing Then
Try
acadApp = GetObject(, "AutoCAD.Application.17.2")
Catch ex3 As Exception
acadApp = Nothing
End Try
End If
acadDBX = acadApp.GetInterfaceObject("ObjectDBX.AxDbDocument.17")
Catch ex2 As Exception
MessageBox.Show("Error Connecting to AutoCAD", "Autocad Message", MessageBoxButtons.OK, MessageBoxIcon.Stop)
End Try
End Try
End Sub
{code}
