Problem in deleting the windows registery key and it's sub key
-
Hi I have again some problem regarding windows registery. I am trying to delete a key and it's sub keys and all the corressponding values. Here is the code which I am using: HKEY m_htKey; LONG res; const char* lpSubNsKey = "SOFTWARE\\N K Product"; res = RegOpenKeyEx(HKEY_CURRENT_USER ,lpSubNsKey,0,KEY_ALL_ACCESS,&m_htKey); if (res == ERROR_SUCCESS) { //res = RegDeleteKey(m_htKey,lpSubNsKey); LONG status = SHDeleteKey( m_htKey,lpSubNsKey); RegCloseKey(m_htKey); } In the above code,the RegOpenKeyEx() is returning 0 means registery is getting opened but the SHDeleteKey() is returning 2 i.e. it's error code message is "The system cannot find the file specified". But the key name is available there in the registery. So,can you please suggest me what could be the problem?

You're passing the handle you got back from
RegOpenKeyEx, which in effect means you're askingSHDeleteKeyto deleteHKEY_CURRENT_USER\SOFTWARE\N K Product\SOFTWARE\N K Product, which presumably doesn't exist. Simply passHKEY_CURRENT_USERas the first parameter toSHDeleteKey, and don't bother callingRegOpenKeyEx.Stability. What an interesting concept. -- Chris Maunder
