Manipulating WinXP-32bit Registry

reverse · 05-04-2007, 12:07 PM

Having not worked with Windows in a few years, I have no idea where to find documentation for this kind of thing. I'd like to be able to make some simple actions on the Win Registry (basically: read things from it). Preferably I'd like some documentation on how to accomplish this using x86 assembly, however, C/C++ oriented docs would be just as good. I do not wish to use 3rd party libraries. (book recommendations are welcomed as well)

MSDN is the place for this sort of info:

Hi -

The Win32 API for reading the Registry is basically just:
RegOpenKey (or RegOpenKeyEx)
RegQueryValue
RegCloseKey

You can easily Google for code snippets, and write a 10-line C/C++ program to read the registry in no time flat. If you were interested in the assembly output, you could just as easily compile with "cl /Fa" and look at the .asm output.

But if you were interested in delving a bit deeper - into how the Win32 API actually *works*, here's a good article:

Thanks! I'll have a look into it.
