I am sorry, I forgot my telescope today and am unable to see your monitor. Can you please elaborate more on what the problem exactly is? How exactly are you dealing with the registry and what exactly does the registry function returns?

Thanks for your replay. I wrote an applcation in vc++ 2005,in which I create a new registry key and set some value. This one work proper in xp and vista. I port the same code to vc++ 2008. It works in xp, but not in vista. I hope you can understand my problem. Thanks.

Aren't you using some function which would create the new registry key? What is that function returning when you say it wasn't working?

Thanks for ur replay. long lRet = RegCreateKeyEx(HKEY_LOCAL_MACHINE,_T("Some Path"), 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hKey, &dwDisposition); lRet is 5 in the case vc++ 2008 and in the case vc++ 2005 lRet is 0

The documentation for RegCreateEx says a non-zero value is returned, when the function fails. 5 is a non-zero value AFAIK. The documentation also says: use FormatMessage()[^] with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.

I would suspect it's an access denied error since you're writing to HKEY_LOCAL_MACHINE. Your app needs to run with elevated privileges to do that. Mark

Mark Salsbery, Yes, this is access denied error, could you please explain how to overcome this problem. Thanks in advance.

Writing to HKEY_LOCAL_MACHINE requires the code to run with administrator rights/elevated privileges. Does it work if you run your app as an administrator? Why do you need to write to HKEY_LOCAL_MACHINE? That should generally only be done at install time (running elevated). If you have common application data that needs to be shared between users, then you should store that at the recommended application shared data folder, not in the registry. Unless, of course, all users of your app have no problem running the app as an administrator. Mark
