IMPLEMENT_OLECREATE & Automation

Hi,

I am trying to enable OLE automation in one of my applications.  I want to use the IMPLEMENT_OLECREATE macro, however i am having difficulty.

this is the macro as mentioned on the msdn website.

IMPLEMENT_OLECREATE(class_name, external_name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8 )

I have several questions.

1.  class_name - What class  my CWinApp Derived class?
2. i understand the " l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8 " part is the clsid of the application.  How do i find out what my clsid for my app is?

thanks, also if you can point me in the direction of a good how to do on this that would appreciated

Aplogies,

I left out the DECLARE_OLECREATE(name) in the .h file.

Mahesh,  I know have most of the application up and running (so to speak).  My application is an Exe that has interfaces in it that external applications can access and use for automation.  I have added a new interface for my new class.  I have written a quick app (in c#), litterally a form with a button on it, that when clicked should instantiate my application object.

The problem i am receiving is

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in WindowsApplication1.exe
 Additional information: COM object with CLSID {157A834E-77AD-4012-8437-3BB3C9007E2E} is either not valid or not registered.

I have checked through the object browser and it can see the object i am trying to instantiate, i have taken this project over from someone else who set up the other interfaces and i dont know how they "registered" them.  Any ideas

Many thanks

Will
