Afternoon Sam.

If AutoCad is similar to Microsoft Office, the Class Type references only the most current version installed, which would be AutoCad 2007 in your case. Fortunately, the first Argument for GetObject is Path. If you execute GetObject("C:\ProgramFiles\AutoCad LT 2006\AutoCad.exe") or whatever the path is, it should only get the AutoCad LT 2006 version.

Hope that helps you some.

Hi shamsam1,

This is correct, you cannot control Autocad LT with the createobject/getobject methods. You can however write a script that will open Autocad LT and insert the drawing(s) that you want and close it.

[shamsam1]

i am using script file(.scr file) to pass value

C:\Program Files\AutoCAD LT 2006\aclt C:\1.dwg /b c:\script.scr

first time when i pass value value ,autocad lt will open and in that i am inserting some dwg file

if i pass value for second time its opening new autocad lt window and it will inset the drawing

i dont want to open new window if autocadlt is open already i want to insert dwg file in active winodw

This is because you are not closing the acad lt. In the script file (.scr) you will need to send all of the commands that are required for that drawing. Calling acad lt from the command line (which is the only way I know of to do this) means that it is all by itself and you have no control. So in the script file close acad after the commands are through. Then start another script. To repeat you cannot reuse an existing instance of acad lt via a script file or anything else other than human intervention.
