Automatically run Script file

Hi All...........

I'm trying to write a macro in Excel-VBA that will start AutoCad and run an
external script file called script.scr

Here's my code so far..........it will open AutoCad and open the test.dwg
file and execute the script command and open a dialog box to choose a script
file, but then will not accept the script.scr filename nor a
"Enter"........it just hangs there



Sub StartAutocad()
Dim oAutoCad As Object
Set oAutoCad = GetObject("c:\test.dwg")
oAutoCad.sendcommand "script" & vbCr 'this line opens the choose
file dialog box
oAutoCad.sendcommand "script.scr" & vbCr 'this line don't appear to
work at all

Any help would be appreciated..........

Vaya con Dios,
