RegistryKey ValueCount/SubKeyCount wrong
- by Mark J Miller
I am trying to query the following registry key values:
HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SharedMemoryOn
HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SuperSocketNetLib\ProtocolOrder
But depending on which machine I'm running the program the query returns null. When I debug on my local machine and I inspect the value for ValueCount for:
HKLM\SOFTWARE\Microsoft\MSSQLServer\Client
HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SuperSocketNetLib
The count is 0 and OpenSubKey returns null.
I am a domain admin, in the local administrators group and have added the following to my app.manifest:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
Any idea why?
private static void ValidateSqlClientSettings()
{
Console.WriteLine("\r\n/////////////// LOCAL SQL CLIENT PROTOCOLS ////////////////");
RegistryKey keyHKLM = Registry.LocalMachine;
///TODO: nullreferenceexception - connect to remote machine and find out why
RegistryKey sqlClientKey = keyHKLM.OpenSubKey(@"SOFTWARE\Microsoft\MSSQLServer\Client");
if (sqlClientKey == null)
{
WriteLine2Console(@"WARNING: unable to read registry key '{0}\SOFTWARE\Microsoft\MSSQLServer\Client'", ConsoleColor.Yellow);
}
var cliKeyNames = from k in sqlClientKey.GetSubKeyNames()
where k == "SuperSocketNetLib"
select k;
///TODO: find out why these values are always missing (even if I can see them in regedit)
Console.Write("Shared Memory Disabled (cliconfg): ");
if (Convert.ToBoolean(sqlClientKey.GetValue("SharedMemoryOn")))
WriteLine2Console("FAILED", ConsoleColor.Red);
else if(sqlClientKey.GetValue("SharedMemoryOn") == null)
WriteLine2Console(String.Format("WARNING - unable to read '{0}\\SharedMemoryOn'", sqlClientKey.Name), ConsoleColor.Yellow);
else
WriteLine2Console("PASS", ConsoleColor.Green);
Console.Write("Client Protocol Order (cliconfg - tcp first): ");
foreach (string cliKey in cliKeyNames)
{
RegistryKey subKey = sqlClientKey.OpenSubKey(cliKey);
object order = subKey.GetValue("ProtocolOrder");
if (order != null && order.ToString().StartsWith("tcp") == false)
{
WriteLine2Console("FAILED", ConsoleColor.Red);
}
else if (order == null)
{
WriteLine2Console(String.Format("WARNING - unable to read '{0}\\ProtocolOrder'", subKey.Name), ConsoleColor.Yellow);
}
else
{
WriteLine2Console("PASS", ConsoleColor.Green);
}
subKey.Close();
}
sqlClientKey.Close();
keyHKLM.Close();
}
