Can you please show us the relevant code? Because 1. We can't answer solely on assumptions 2. And there's a pillar right next to your cubicle, so I am not able to see your monitor.

i think u r buffer size may be 25 characters or u r writing only 25 characters

MFC has an API for the registry? :confused:.

Be aware that RegSetValueEx's cbData parameter should be the size of the string expressed in bytes, i.e. (string length + 1)*2 for UNICODE strings. :)

Hence run the program as administrator. :-D Seriously, I don't know. Maybe you'll have more luck on Vista[^] forum. :)

Could you please post the relevant code?

RegCreateKeyEx ( hkey, (LPCTSTR) str1, 0, NULL, REG_OPTION_NON_VOLATILE,
KEY_CREATE_SUB_KEY | KEY_ALL_ACCESS, NULL, &childkey, &dispos ) ;

RegSetValueEx ( childkey, (LPCTSTR)str2, 0, valur_type, (const BYTE*) (LPCTSTR)str4, (str4.GetLength()+1)*2 ) ;
RegCloseKey ( childkey ) ;

I don't see any REG_BINARY in your code. BTW To maintain generic text mappings, I suggest you to change from (str4.GetLength()+1)*2 to (str4.GetLength()+1) * sizeof(TCHAR) . :)
