public string GetRegistryValue(string ValueName,
	string DefaultValue,
	string Node);

ValueName
The name of the Value in the Registry.

DefaultValue
The value to return if the name isn't found in the Registry.

Node
The name of the node in the Registry that the value can be found in.

        If a value is passed and it doesn't contain a backslash (\), that node is used instead of Options. 
        For example, specifying "Data" means that "HKEY_CURRENT_USER\Software\CompanyName\ApplicationName\Data" is used. 
        If it does contain a backslash, then it must be a complete path to any place in the Registry, such as "HKEY_LOCAL_MACHINE\Software\Whatever\SomeNode".
