RegOpenKeyEx giving error 2 or error 161, fails both ways

Question

I am trying to read a registry key from a Windows server, and I can\'t seem to get it to work either with or without leading slashes. If I try:

lError = Reg         


        

Answer 1

Open the key, not the value:

lError = RegOpenKeyEx(HKEY_LOCAL_MACHINE,
                      "SOFTWARE\\Company\\Product",
                      0,
                      KEY_QUERY_VALUE,
                      &hDomainKey);

and then read the value using RegQueryValueEx() (or RegGetValue()).
