Hi Arman, I found out the solution for error C2504: 'AnyObject' : base class undefined My tlb is dependent on some other tlb so, what i did is I #import the base tlb before importing my tlb. It complies fine. There are no errors. But, I am not able to get pointer to my COM object, when I am running following sample code CoInitialize(NULL); IMyComObject pObject(_uuidof(MyComObjectName)); I am getting following error in CoCreateInstance method 0x80040154 Class Not Registered I checked the registry, there is an entry for my typelib. I am not sure why it is not able find the class. Any suggestions/help please.. Thanks in advance JK

Thank you all, I am able to get the COM object. There was couple of mistates I was doing while creating CoCreateInstance. Now it works fine. Thanks JK

It looks like it should work. Without seeing the resource script I can't imagine. You could try AfxGetInstanceHandle() instead of NULL for the module handle. Also make sure the type is a string and not a macro for an integer. That's all I can think of off hand... Mark This episode brought to you by the number 5

Hi All, Thank you very much for all your help.. I think its good idea to rewrite the code in VB.NET. Thank you all JN

Taking a wild guess here but you might try making your account a member of the "administartor" or "Debuggers" user groups.
