Buck,
While this has gotten me a bit further, I seem to have missed something.. See my screen shots This generates the dropdown option, however i get an error. Don't get too huffy with me.. I never play with regedit... this is new turf for me. There is an option for creating different types of "Keys" I chose a "String" I thought bionary was clearly not correct. In any case this is what is in the VB Script File.
On Error Resume Next
dim cmd_arg
set cmd_arg=wscript.Arguments
Dim acadApp
Set acadApp = GetObject(, "AutoCAD.Application")
If Err Then
Err.Clear
Set acadApp = CreateObject("AutoCAD.Application")
End if
acadApp.visible=True
acadApp.WindowState = normal
acadApp.Documents.Open cmd_arg(0), True
Where Did I go wrong?
