Hi All,

I am writing a C code to read a registry key. I am getting error “error C2065: ‘HKEY’ : undeclared identifier”.

This is a forum about writing and developing device drivers , not for “general” questions. What about doing a “Google” for a code
snippet from which you can "copy and paste " ?

Any suggestions?

Thanks,
Harsha

If this is a driver, HKEY does not exist. You just use a HANDLE.

User-mode or kernel-mode?

If kernel mode, use HANDLE, not HKEY.

Thank you. I defined the key as HANDLE. But then it is giving error: not initialized. What is general initializing value for type HANDLE?

Please post a snippet of your code. You’re probably misunderstanding how to
use the registry functions. Posting a snippet will allow us to see exactly
what you are doing, rather than guessing over multiple iterations of email.

NULL, but the real question I have is why you are asking a C programming
101 questions in an environment where you should know such things, or at
least HOW to find out the type definition of HANDLE. You know . put the
cursor on HANDLE, do a right click and select definition?
