Good luck getting help on these forums. More than likely you will get Tony Tanzillo telling you what an idiot you are for even asking.

my experience with ADN was not much better. you would think that paying $1300 for tech support would render something useful.

This is a sub that I wrote in VB.NET to change a layer's freeze state. With the quick research I did I could not find a mechanism for finding a specific layer without looping through them...

{code}
Sub freezeMe(ByRef tr As Transaction, ByVal lname As String, ByVal freeze As Boolean)
Dim lt As LayerTable = tr.GetObject(HostApplicationServices.WorkingDatabase.LayerTableId, OpenMode.ForWrite, False, False)
For Each i In lt
Dim tt As LayerTableRecord = tr.GetObject(i.GetObject(OpenMode.ForWrite).ObjectId, OpenMode.ForWrite, False, False)
If tt.Name = lname Then
tt.IsFrozen = freeze
End If
Next
End Sub
{code}
Each element in the LayerTableRecord has properties of the layers such as isFrozen, isLocked, etc. See the helpfiles for a full list of properties.

Opening a drawing is fairly well documented in the samples, helpfiles and on these forums.
