COM

Hi,

I have a COM exe and 2 dll's. These 2 dll's will use the interfaces of the COM exe.

I want only one instance of the COM exe to be running. How do I do this ?

Can a COM class be made singleton ? If yes, please let me know how to achieve this.

or any other approach to ensure that only one instance of the COM exe would be running would be appreciated.

Thanks.
