Launch AutoCAD and Create a Search File Path

Anonymous — Thu, 06 Mar 2003 10:35:01 GMT

' Hi,
' I did the below bit and pieces code to launch AutoCAD from my exe and also
' to create a new Search File Path from where I launched folder, but only
works if I have AutoCAD already opened
' not from scratch (from the exe) it always create the path from:
\windows\system32
' can someone test this is for Visual Basic, thanks Luis E.

Scrap the IsAutoCADOpen() function.

Luis,

It worked prefectly for him so maybe I'm missing something. Perhaps more explanation would help.

Here is my previous code that I want it to update for AutoCAD 15, can you
tested please (is not working...):

What I want to do is to launch autocad from my exe and create a support path
from where I have my exe.

thank you,

using Luis's first code I am getting an error, that described as "Call was
rejected by callee."
I am working with Acad2002 and VB.NET
Do you have some suggestions?
