VB & COM+ -> Visual C++ & COM+?

[ncage]

It has been a couple years since I have programmed in C++ but it wouldn't take me long to get up to speed at all. I currently work in a 3-tiered environment with visual basic, com+, MMQ. We have been having some performance problems with our middle-tier visual basic dll's. I want to learn visual c++ for trying to improve the performance of some of these dll's. I am not worried about learning the display/MFC portion I just want to be able to work with Visual C++, COM, COM+, and everything needed for making efficient middle-tier dll's. I don't want a book that expects expertise in Visual C++ technologies like MFC but I don't want a book so simple that it expects I don't know anything about C++...can anyone recommend one really good book?

There's a lot of obsolete info out there... If you're looking to keep the bulk of your code in VB, check out Programming Distributed Applications with COM+ and Microsoft Visual Basic 6.0, Second Edition; otherwise there's good stuff in COM+ Developer's Reference Library and, of course, a download of the July 2000 COM+ platform SDK with its many samples.

FWIW, if your apps was truly written in all VB, then it's likely your connection pooling that's killing you. Each of the above spell out options with C++ to fix this... MSMQ also has it's drawbacks, so check out LCE too.

Hope this helps.


Oh, smart quotes, eh? How about:

"A bad workman never gets a good tool."

"An artisan who has only a hammer in his toolbox thinks he can fix everything with a hammer."

I'd be interested in hearing where you think perfomance problems/bottle necks are.

I'd like to know what performance problems with VB/COM+ components you think VC is gonna fix...
