COM environment

[Knoxster]

Can someone please explain to me what exactly a COM environment is, what it does, and how I can implement one? Apparently I need to implement one so that I can use a dll file and allow transactions between it and my application. I am highly uninformed on this topic.

Thanks,
Colin

Well, first of all... COM isn't an environment. It's more of a methodology...
Common
Object
Model
But COM is only the first half of it. In order for you to implement transactions, you'll also need to learn about MTS (Microsoft Transaction Server) which will allow you to use COM objects in transactions. If you can, pick up the book "VB6 MTS" from Wrox press. I think there is also a "VB COM" book by the same publisher. You'll probably want to read that one too.

is this required for me to use an ActiveX DLL? or am I able to just package an application with the DLL and make calls to the DLL?

Question on the side.... apparently I only have VB 6.0 "Learning Edition" installed on my pc... what edition of VB 6.0 is required for me to be able to create ActiveX DLL's? is this also capable in VB .NET?

Thanks,
Colin
