Hi Tony, thank you very much for your help.
To solve this problem I'm making an AutoLISP program to 'translate' the Lisp
data to 'normal dictionaries' and xrecords with DXF codes, also, I'm making
a C++ program that automates AutoCAD for open the DWGs and translate it; I
tested both and work fine, but then, I have installed R14.01 for get old
data,
and my program for automate has problems in the following code:
CLSID clsid;
if (::CLSIDFromProgID(OLESTR("AutoCAD.Application"), &clsid) != NOERROR)
//Here is the problem!!!!
{
::AfxMessageBox(IDS_ERROR_ACAD);
return FALSE;
}
It does not work neither R14.01 nor 200X, ¿how can I say to
'CLSIDFromProgID()'
that I need get an specific AutoCAD version?, first 200X and then I have to
chage the code for R14.01. Please, help me, I need automate both versions.
Thanks in advance,
William G.S.
