Microsoft SDK and COM

hi,
What is Microsoft SDK ? How and for what is it used for?
What are the tools used to create COM objects. Is knowing VB enough to create advanced COM objects.

Thanks

SDK is a software development kit. There are several (like SOAP for XML, and Platform SDK for C++), and you can download them from MSDN


VB COM is fairly advanced, but it does a lot of stuff behind your back, so that you never REALLY know what you're creating.
Rather than going on about it, try the Wrox book 'VB COM'.
It isn't hard to read, and if you stick with you'll know far more about than most VB programmers who have been at it for years.

To get deeply into COM or COM+ requires coding in C++.

My recommended reading has to be Ted Pattisons 'Programming Disributed Applications with COM+ and MS Visual Basic 6'

Read this and you will be able to converse with any C++ programmer as near equal. A lot of C++ programmers know the technique, but not the theory (the whys, and why nots) Even a seven year old programmer can follow a script of things to do.

This book is also on the required reading list for Microsoft programmers.
