ATL ObjectArx works from Acad VBA but not from VB

Anonymous — Wed, 31 Jul 2002 14:10:50 GMT

Hi All,

I'm trying to create a ATL (COM Application) and I'm confused here.

First scenario:
I created a ATL project, added an ATL Object & added a method to it,
then I added the ObjectArx code and it loaded fine in AutoCAD Map and the
AcadTest module run successfully from AutoCAD Map.

I wrote a simple module in AutoCAD Map VBA to communicate with the ATL
Object I created and it worked fine.

The problem is when I copied the same code in VBA under Excel, it gave
me an error when creating the Object "Set sTest = New MyAtlObject.MyMethod"
it gave me the following error: "Automation Error. The specified module
could not be found"

The second scenario:
I created an ObjectArx project from VC++ and added an ATL Object from
the ObjectArx Toolbar, and created a method.

I end up with the same problem.

I even made a reg file for the application with no luck. Also when I try to
run the "Register Control" from the VC++ "Tolls" menu, it gives me the
following error: "The specified module could not be found".
Can anyone tell me what's wrong here as this is driving me nuts. Your help
will be deeply appreciated.

Best regards

Wael Bakr

An ARX COM server must be loaded into AutoCAD's process
(either as an ARX module or a standard COM server).

To do this from an out-of-process client, you have to
use the GetInterfaceObject() method of the AutoCAD
Application object.

When you create an ActiveX object using the 'New' keyword
in VB or VBA, it tries to load the ActiveX object into the
host process, which is not Acad.exe.

Just load your COM server like this:

Dim Acad As AcadApplication
Dim YourObject As .
Set Acad = GetObject(, "AutoCAD.Application")
Set YourObject = Acad.GetInterfaceObject("")
