Is there an easy way to export a bunch of registry keys into a .reg file. I need to create a setup for an update but I would like to write a 'backup' of the registry keys onto a file in the application directory. It's not enough to put the keys in memory, I really need to put them in a file too

I did this once, but I don't have the code here right now. You basically call regedit.exe with the /e command line, and then specify a file to export to. I think I had this implemented as a backup of user settings, and I think I wrote it to MyDocuments with a file name and a time/data stamp in the file name.

regedit.exe /e c:\export.txt "HKEY_LOCAL_MACHINE\SOFTWARE\YourCompany\YourApp\"

Cool. I always wondered if one could export registry settings from the command line, so thanks Glytzhkof. This will come in handy.

Managed to get it working in my installshield project. Though I'd post it here, could be useful to other people too (don't mind the few dutch words, I'm from belgium)

function exportreg()
STRING deel1,deel2,deel3;
begin
deel1 = WINDIR ^ "regedit.exe";

//dline.exe onder app paths
deel2 = "";
deel2 = "/e /s ";
deel2 = deel2 + TARGETDIR ^ "regbackup1.reg";
deel2 = deel2 + " " + "\"HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\App Paths\\dline.exe\"";
LaunchAppAndWait (deel1 , deel2 , WAIT);
end;

Thanks for that follow up hans, good reference. I think the function I created was very generic. I think I will forward this to Stefan when I get access to it. Might be useful for someone, and it is always a shame to have people write the same damn code over and over.
