vb.net routine - autocad says unkown command

I have no idea why autocad 2012 refuses to load this, or it is loading it but something else is causing the command to not be known.


I have no errors in visual studio & I get no errors when I netload.

I'm sure there are logic errors since I haven't been able to debug this yet (migrating it from VBA to VB.NET)


any help would be appreciated.


the start point / command is in Class2 in vbLayerGroupController


ACF & ACGen contain functions called by my routine.


While trying to figure this out, as a test, I had created a new class with a generic msgbox command within this project & it worked (I removed it now), so there is something in here that autocad doesn't like.

In your class2.vb file, add this line after the "Imports..." instruction and before the class LayerGroupController, like this:


Imports Autodesk...

Imports .....


<Assembly: CommandClass(GetType(LayerGroupController))>


Class LayerGroupController



    Public Sub LayerGroupController()


    End Sub

that worked.

what is it? why?

I don't have that in any other projects that work.




I would have NEVER figured that out.


also, useful tip for anyone out there (maybe):

I set option strict  = ON, & a lot of errors revealed themselves.

I've been leaving it off because there always ends up being at least one thing I can't resolve, like with this program there was one late binding error (keep in mind I haven't begun to debug this yet since I haven't yet been able to enter my command in autocad to start the process):




ForEach Ent AsObjectInACF.ThisDrawing.PaperSpace

If Ent.ObjectName = "AcDbViewport"Then
