Current Layer

[sapersing]

I am having an issue setting a layer to the active layer in vb.Net 2005.

We use lisp commands to thaw several layers at a time.
Ex:
(DEFUN C:TEST ()
(COMMAND "-LAYER" "T" "TEST1" "S" "TEST1" "F" "*" "T" "0, TEST1, TEST2" "")
)

I encounter my problem when trying to use the above command in .Net:

Dim acadApp As AcadApplication = CType(Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication, AcadApplication)

acadApp.ActiveDocument.SendCommand("TEST" & vbCr)

AutoCAD will show in the layer properties manager that TEST is the current layer.
However, if I do a query after the SendCommand line of code (Ex: MsgBox(acadApp.ActiveDocument.ActiveLayer.Name)), it tells me that the active layer is the 0 layer.

Anybody have any ideas?
Any help whatsoever will be greatly appreciated.

Don't use SendCommand.

Were you thinking along the lines of SendStringToExecute?
I tried the following but it didn't work either:

Dim acadApp As AcadApplication = CType(Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication, AcadApplication)
Application.DocumentManager.MdiActiveDocument.SendStringToExecute("Test" & vbCr, True, False, False)
Dim startPoint() As Double = {100,100,0}
Dim endPoint() As Double = {200,200,0}
acadApp.ActiveDocument.ModelSpace.AddLine(sp,ep)

Above puts the line on the wrong layer.
Is there another method you or anyone else can think of?

Sendcommand executes asynchronously - meaning you can't be sure if the
current layer is changed BEFORE the rest of the code is executed. Not sure
about SendStringtoExecute - but it looks like it based on your code. Why
aren't you setting the active layer property on the activedocument object?
Why use lisp for this?

I am using the lisp function because my company has around 250 of these little lisp functions in use.
Each of these freezes layers, thaws layers, sets linetypes, dimensions styles, snaps, and grid options.
I was hoping not to have to convert them to .Net but it looks like I am going to have to.
