I have an ATL COM object compiled with VC 6.0 that needs to be compiled in
Visual Studio .Net 2003. So, I going from the 6.0 compiler to the 7.1
compiler. I got the project converted, compiled and linked
without errors. It registers correctly but it will not instatiate as an
ActiveX control in my classic ASP pages. I get the "ActiveX component can't
create object" message.
What am I doing wrong?
Thanks,
Sherry

Do you have the all DLL's installed? New CRT 7.1, new MFC DLL 7.1. Use
depends and look what additional DLLs are needed.
 
Hey Martin,
Thanks for responding. I looked at depends and the only required dll that
doesn't have a linker version of 7.0 is oleaut32.dll. Looking at Microsoft's
DLL Help database, I found that the only version later than mine for Windows
XP is for SP2 which I haven't installed yet. And I don't really want to
upgrade to SP2 just to find out that it doesn't solve my problem. Besides
which, I can't force our clients to upgrade just to run this one dll.
I checked Event Viewer and there were no messages in there regarding my dll
either.
Anything else I can check?
Thanks,
Sherry
 
Martin,
The problem with my dll was E_OUTOFMEMORY. I rewrote the code the use a map
instead of an array of strings and that fixed the problem.
However, I had another dll that wouldn't register on the server and I
checked the dependency walker per your suggestion and found that I was
missing MFC71.dll.

Thanks very much for your help,
Sherry
