VB6 how to load other user registry hives and write the content of a .reg file

if you wish to change the registry entry for all users on a single machine, simply modify the LOCAL_MACHINE registry hive.
can you post an example of .reg file you wish to write to the registry?

can u check if the registry path in this file are also existed in the LOCAL_MACHINE?

Thanks sedgwick,

I did. Unfortunately they don't exist in the LOCAL_MACHINE key. I have so far managed to load each user's registry hive through my program. What I'm having difficulties with is to run the reg file so it would get inserted in to the loaded hive.

Many thanks again

how did u load each user's registry hive ?

With the following code

in the reg file you've posted earlier (ID:33508573) there are 6 registry entries.
are they correspondent to the 6 users of the machine?

Thank you so much. That gave me the basic idea. I went on and loaded each hive and wrote to the registry through coding instead of trying to run the .reg file.

That did the trick. Really appreciate your assistance.
