And, what is the return value of "RegCreateKeyEx"? Did it succeed?

Did you read the documentation? The first very parameter that you should supply RegSetValueEx should be a handle to an open registry key. I don't see you opening a key, but you are right out trying to set a value. Neither do you check if the call to RegSetValueEx succeeded. May be you should see a sample in MSDN which explains the usage of this call.

The 6th parameter of RegCreateKeyEx is the desired access mode. You are passing 0. Try using KEY_SET_VALUE.
