Plz anybody tell me How to read the registry file....

It's a bit like how to read a file, but you're going to read the windows registry. First you have to call RegOpenKey() to get a handle to the registry key entry, and then RegQueryValueEx() to acaully read the key entry, finally RegCloseKey(). You can find all those functions, and others too, from here

If you want examples, then just use google and you will find lots of them.
