Changing Registry programaticly

Hi to all!
I'm trying to change "GlobalUserOffline" in registry from my application.
this is the code I'm using:

HKEY hkey;
DWORD m_tmpWord;
RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings", 0, KEY_ALL_ACCESS, &hkey);

When I start application everything looks OK, but there isn't any change in registry.
What I'm doing wrong.

OS is Windows 2000, IE 6.

Try to use RegOpenKeyEx with KEY_READ security attribute.
