Very Simple COM Example Please

Hi

This is not homework

I want to write a simple com component that has a single class RandObj and a single method GetRand(ULONG range). i do not want to use any VC++ wizards MFC etc (i will later once i know how it all works), i am usung VC++ 5 though.

i need the code for the com component and a simple client that will call the component . also need istructions on what to put in the registry.

i want to use this as an in-process server so i dont need to get involved with IDL etc for the time being

i will ask another question after this on how to IDL it so it can be DCOM etc

Thanx

Paul

Hi Paul,

Its the best way to start learning com.

I suggest you to go thru Inside COM by DaleRogerson.

He gives you an example to write component

using c++ ..etc

Do read this book +vely

In Petzold's classic book(chapter 20) you can find very
simple example of this . If yoy want, I can send you
example of code(write your EMail).

Download the Platform SDK samples - the COM samples vome in abundance, and they also contain all 'Inside OLE' code.

Well, a smaller sample can be found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/shellcc/shell/shell_int/contextmenuhandlers.asp - it demonstrates a context menu handler and several other 'neat' UI stuff, and IMHO also serves as a COM starting point...
