I have an external drawing processor and one of the functions is to read the layers in an AutoCAd drawing and if the name matches freeze/thaw it. With modifications over the years I have had it working with 2002 through 2008. Now I'm getting errors. When I tru to use the Interop, I get "Call Rejected by Callee" errors, when I use the
ApplicationServices method to get the application and active document, I getI" Method 'GetEnumerator' in type 'Autodesk.AutoCAD.DatabaseServices.LayerTable' from assembly 'Acdbmgd, Version=188.8.131.52, Culture=neutral, PublicKeyToken=null' does not have an implementation." errors.
Basically for the interop method I use this code:
Imports Autodesk.AutoCAD.Interop Public Function GetAcadApp() As AcadApplication Dim progID As String = My.Settings.strAcadProgID Dim acApp As AcadApplication = Nothing Try acApp = DirectCast(Marshal.GetActiveObject(progID), AcadApplication) Catch ex As Exception Try Dim acType As Type = Type.GetTypeFromProgID(progID) acApp = DirectCast(Activator.CreateInstance(acType, True), AcadApplication) Catch ex2 As Exception MessageBox.Show("Cannot create object of type """ & progID & """") End Try End Try If acApp IsNot Nothing Then End If Return acApp End Function GetAcadApp acApp.Documents.Open("drawing path here", False) for each layer in acApp.ActiveDocument.Layers If layer.Name Like "XYZ" then '''''HERE is where I get stopped by Call Rejected by Callee layer.Freeze = False end if acApp.ActiveDocument.Regen(Common.AcRegenType.acAl
lViewports) Next layer
As for the other method, I use the sample code provided in the Autodesk wiki modified to be used outside of AutoCAD (I can post it if necessary)...
I just can't figure out why I'm being rejected. Any help would be greatly appreciated!
It may be worth noting that the sample code from Kean's blog doesn't bother to revoke the IMessageFilter, so caveat emptor.
I can find a boat load of sample code for vb.net that works inside of AutoCAD, however, I’m creating an windows vb.net app that runs outside of AutoCAD and MS Access that I can select blocks inside of AutoCAD and populate tables inside of MS Access. I would greatly appreciate it if you can point me in the right direction where I can find documentation using Autodesk.AutoCAD.Interop and Common.
I’m having problems translating code from acmgd,accoremdg to the interop world.
With stand-alone EXE app, you DO NOT/CANNOT use AutoCAD managed API assemblies (acdbmgd/acmgd/accoremgd.dll). You are purely dependent on AutoCAD COM API. So, do not "translate" .NET API code, use COM API.
Well, unless you do not mind to make things complicated - often unnecessarily - by writing .NET API code that runs inside AutoCAD and expose it as COM so that your external app can communicate with it. Form the simple task as you described (accessing AutoCAD block information in drawing), this is indeed unnecessary to expose your own API for external app, instead of using good old COM APIs.
