Does anyone have a smal example of how to programmatically, in c/c++, load a users registry hive? I would loike to load a hive set some values and close the hive.

Thanks in advance for any help.

You can use RegLoadKey() and RegUnLoadKey(). You can build the paths to the user hives (NTUSER.DAT) via the HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. However, it's generally not a good idea to use these functions willy-nilly. If the user tries to logon while you have his profile loaded, he will be unable to load his profile and will get a temporary default profile.

Documentation says you should pass predefined key HKEY_CURRENT_USER as first argument of RegOpenKeyEx function. You can also enumerate HKEY_CURRENT_USER passing it directly to RegQueryInfoKey.

I haven't got a specific example, but the Windows API calls you need would be:

  • RegOpenKeyEx() to load the registry key
  • RegSetValueEx() / RegGetValue() [and sister functions] to get/set registry values
  • RegCloseKey() to close the registry.

There's some example code behind this link on codersource.net ... although I can't vouch for how complete or correct it is. Review against the MSDN :-)
