printing files silently from c++ application using DWG TrueView

[Anonymous]

Hi all,

sorry if I'm posting into wrong forum.

I'm trying to automate DWG TrueView to print my files using my c++ application. I noticed that it comes with COM interface.

here is my code:

CLSID clsid;

lHr = CLSIDFromProgID(_T("AutoCAD.Application.19"), &clsid);

if(FAILED(lHr)) throw(0);

IDispatchPtr lApplicationDisp;

lHr = lApplicationDisp.CreateInstance(clsid);

Looks like I got the right clsid, but CreateInstance hangs for a while and then returns "Server execution failed" error. Do you know why? Is that even possible to do?

thanks
