Hello! everyone!

AutoCAD::IAcadApplication *pAcad;
CLSID clsid;

HRESULT hr= ::CLSIDFromProgID(L"AutoCAD.Application", &clsid);
if (FAILED(hr))
return;
HRESULT res=::GetActiveObject(clsid, NULL, &pUnk);
if(res != S_OK)
  return;

It's AutoCAD program,Now I want to automate it by COM in my app.

Now the problem is GetActiveObject(clsid, NULL, &pUnk); I cann't get more control on it.
i.e
IF the user have several AutOCAD instances running . And How I can guarantee that always get the most newly created one?

And if my app startup the autocad by ShellExecuteEX then I can get the Hanlde of it.

By this Handle, May I get it's corresponding Com's object?

THANKS!

First: For details about the AutoCad autimation you better consult some forums of the Autocad-community.

Second: Why havent you read the doc about ShellExecuteEX ???

My answer is "No" but maybe there is a way.

To run with COm objects you need to start with COM. Create an instance and make it run.

You better asks that questions in AutoCad forums or the product specific support. ;-)
