What's COM

Hi

I'm new to this area of VB. and would like to learn few things about COM. Well there are enough books. but they cost very much and say the same thing. Can any one give me some examples of COM and it's usage, advantages.

Thanks in advance ;)

COM = Componenent Object Model

It's simple. You create an image file (dll exe or ocx) that only exposes a binary interface. This means that anyone calling the functions listed in the interface knows nothing about what goes on behind the interface. The means of enumerating the interface functions is fixed in a special interface, IUknown.

The component that exposes the binary interface is a COM server object.

hmmm

Thanks guys, It's really interesting I think I should read some notes and see some examples.

he he So I started learning COM and now a another one for u guys.

Now I create DLL files using vb. how can I install this dll. is it the same way we used to install out VB programs.

and to call a function on that DLL would the following line be enough

MyProgram(parameteres)

or do I have to do something more in here ?
