dealing with .reg files

[Troy Lundin]

I have a .reg file that I want to import to the registry. How would I do this?

I don't have one currently lying around to test with, but since you can double click as a user, I assume you mean from code. Try using ShellExecute with the appropriate parameters (I don't know if you need to specify regedit to run it or not - as I say, I don't have one to test with just atm).

Hi all. Been browsing this forum for about a fortnight now, registered just a few days ago, and this will be my first post. This topic actually fits perfectly with the first question i was planning to ask. I've been doing a fair bit of registry manipulation lately, and i've run into a similar problem to Troy. I have a very large binary value that i need to add to the regisrty, but the length of the string exceeds 255 chars. I was wondering if anyone had any suggestions how how to insert it using the registry api, instead of shellexecute (what im currently using). Any help would be greatly appreicated, thanks  :bg
P.S. GREAT forum, the examples and people on this forum are absolutely priceless for any assembly coder  :U :U

If you are looking to deal with .reg files programatically, you can use the following (GoAsm syntax)

Code Select Expand

MergeToRegistry FRAME pRegFile
uses ebx
LOCAL RegExitCode :D
LOCAL RegCmdLine[MAX_PATH] :B

/*
Merges the supplied .reg file into the registry using RegEdit

This procedure requires a fully qualified path !
*/

invoke ZeroMem,OFFSET RegCmdLine,MAX_PATH

invoke GetWindowsDirectory,OFFSET RegCmdLine,MAX_PATH

invoke szCatStr,OFFSET RegCmdLine,OFFSET RegString
mov al,[pRegFile]
cmp al,22h
