Intercept registry changes
Hello,
Can someone tell me how can I intercept, in DELPHI, registry changes from other applications and block them?

May I ask for what purpose you need that?

For a monitoring software to prevent spyware installation!
Ok, you have 4 choices, I think:
(1) Either write a device driver. You'll need one for win9x and another one for winNT. Unfortunately you can't really do that with Delphi. Or:
(2) Use API hooking. See here: http://help.madshi.net/madCodeHook.htm. Or:
(3) If you only need to watch some specific registry keys/values, you could use "RegNotifyChangeKeyValue".
(4) Alternatively to (3), if you only need to watch some specific registry keys/values, you could also set up a timer and periodically check those specific registry keys/values.

The most usefull is to use API hooking.
But I don't know very much delphi. Coud you write the code?
