Com warapper to be used in VB6

Hello, I'm a systems engineer with strong experience in both C/C++ and VB6. For Visual Basic, I've developed interfaces and COM wrappers with DLLs and object libraries. In some cases, I've also been in charge of the development of the API which extends the functionality of Visual Basic, that gets wrapped in some further stage. I guess you don't have the source code of the base DLL. It's very important to know what it is supposed to do. Depending on its complexity, it's probably required a short documentation of every exported function. The usefulness of the COM wrapper is always defined by the end user. You talk about passing pointers to structs in the (current) DLL level. The wrapper could allow VB to pass its own structs in a one-to-one field correspondence, but maybe you want to ged rid of this work, and pass just a few important values as simple parameters, and let the wrapper to create, fill and pass (to the base DLL) a struct with the rest of fields initialized to some default values you will always use (depending on your case, of course). So, I'm open to suggestions. My development environment is VC++. I will use ATL for this project. Sincerely, DEN!

Hi, I think I can do it:-)! Best regards, netcoder:-)

Hi, I can do it. Please, look PM. Regards, Sergey

Sir, see PM for details, please. Vlad

This can DEFINITELY be done in VB6 as I am completely aware of the issues which are there. We have 2 ways of doing this. Using TypeLib and using Declare statements. I am proficient with both. Even, array of pointers can also be accessed.

Hi sir, please see the PM.

Please check PMB

Hi, I can do it. I ready to start it now!

I can surely do this, done lot of work on com wrapper (ATL), Does this com wrapper contains connections points or not?

we have done this kind thing in past. we can do it better and faster

I have developed a large number of modules in C++, VC, COM, ATL etc. I have also written lots of modules for interaction between VB and C++ components.

Hi, I have over 10 years of Experience under vb6,vc i need the 3 .h files , the name of the dll , and if possible the library for tests

It's a routine. For my references, fell free to contact me on my e-mail. Thanks!
