If you mean can you modify the released version of RegEdit, you probably can't do anything meaningful.

If you mean can you replace regedit with your version, yes.

If you mean can you insert new entries in the registry and modify the data values of existing entries, yes.  There are a number of free libraries that you can use.  Most C++ libraries have the functionality built into them.  Libraries intended for C are harder to find.

Well, I just want to edit the data in a Key.  I would also like to know how to add, and delete regedit keys.

Thanks

Hi People_Code,

Is your C compiler 'just' a C compiler or does it also support C++?

If your using MFC, Visual C++, Borland C++, Borland C++ Builder, or any of several others, there are built-in classes for editing the registry.

If you want to build your own, you can get a good start with source code at:

Good Luck,

You can also use Win API:
   RegCreateKeyEx
   RegQueryValueEx
   etc.
   (see the list in the MSDN)

Those functions don't require C++, you can use them from any pure C program.

Hi migo,

I didn't know that MS provided registry maintenance APIs in their base C libraries.  Cool.

migoEX is right,
The Win API is a pure C interface.

This is the set of Registry functions they offer.

This is a broader list of all the other operating system calls.

Sorry, but I found that none of the answers posted worked.

Look man, chill out.  I didn't know that we had to "clean up" our questions ourselves.  And I tried to use the API code, and the program wouldn't compile when I put the code in.  Yes, I did sit here in silence letting the question fester, but I assumed that I could wait till I found an answer that worked.  Guess not.  Sorry I'm not an "expert" like you.
