Help me in making an exe files

Hi,

Well my problem here is that, i have developed an application that acts as a window explorer, and i make another form like search for files and folders. What i want is i that i want to call that form from the context menu when right clicking any drives and folders. I know how to do that in registry, but my main concern is how to call that single form for search from this menu??? But what i know is that i can only call the exe file when putting the registry key. So how could i do that, i guess the only way is to make another exe which lies in the same project...
I hope you got my point?? Can you help me on this???

Thanks

Regards,
Hamar
