Registry

How can I read Key-value pairs from the registry of a remote computer? I have tried using RegConnectRegistry but the subsequent call to RegQueryValueEx gives 'file not found (error no. 2)' error. How can I solve this problem?

Here's the code that I tried:


l_Ret = RegConnectRegistry(CompName, HKEY_LOCAL_MACHINE, &phKey);         
LPCTSTR =
lpValueName  "SYSTEM\\CurrentControlSet\\Services\\EventLog\\System\\NtServicePack\\EventMessageFile";                        
l_Ret = RegQueryValueEx(phKey,lpValueName, NULL, NULL,lpData,  &dSize);

RegCloseKey(phKey);

You are confused a subkey with a value. Run the Registry Editor, the items on the left pane are keys and subkeys while the items on the right pane are values, which have such attributes as name, data and type. So, you need to call RegOpenKeyEx to open the subkey first and then use RegQueryValueEx to retrieve the value.
