Moving to Vista
-
I'm having a bit of trouble getting my c# app to work on Vista. There is some data my app must store that is common to all users of the machine. In the past, I just stuck that information in the registry. In Vista, however, the keys I try to stick in the registry end up in a "virtual store" rather than where I tried to put them. The problem is that while the location I request is under the HKEY_LOCAL_MACHINE root, the virtual store is under the HKEY_CURRENT_USER root, so the data is no longer common to all users. Any advice on how to proceed? I'd prefer a solution that didn't involve popping up a Window begging the user for extra rights, since it's vital that this functions regardless of the way a user might respond in such a popup. Thank you!

Vista doesn't allow user apps to store stuff in the registry. The data is stored in the user's app folder. I don't know what hoops you have to go through to make data available to everyone that uses a given machine.

The folders discussed by that guy are per-user, but it was still a good direction for me to start looking in as you suggested. After poking around more deeply it appears that one can get a common folder to dump data into with the following command: string dataFolder = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + Path.DirectorySeparatorChar + myCompanyName; Of course if anyone knows of a better place to dump per-machine data, please let me know! Thanks again!

AFAIK that is the right place, not just for Vista, as MSDN describes it: "CommonApplicationData: The directory that serves as a common repository for application- specific data that is used by all users " :)

Use the SHGetSpecialFolderPath() api call with the nFolder parameter set to either: For per user app data (e.g. C:\Documents and Settings\username\Application Data) CSIDL_APPDATA or for app data common to all users (e.g. C:\Documents and Settings\All Users\Application Data) CSIDL_COMMON_APPDATA regards,
