Registry

[Guest]

I'm converting c++ code to c#. Here the interface declarations for the 2
should remain same. so if I have interface declaration as below

object GetRegistryKey(long keyParent, string keyPath, string keyName) in c++
I need to keep it the same in c# also.

basically the function access values inside a registry given the path/name,
also keyparent above refers to hkey (eg:localmachine/currentuser etc.).

In .net we can use Registry and Registrykey to access registry where as in
c++ HKEY values are used, which have values as showed below,

eg: HKEY_CLASSES_ROOT = &H80000000
HKEY_CURRENT_USER = &H80000001
HKEY_LOCAL_MACHINE = &H80000002

now my problem is to convert this long # which comes in as the input to
registry.localmachine. Is this possible if so, how?

Thanks for any help.

You'll have to do the mapping yourself, something like this

const uint HKEY_CLASSES_ROOT = 0x80000000;

....

RegistryKey keyParent;

switch (val)
{
case HKEY_LOCAL_MACHINE:
keyParent = Registry.LocalMachine;

...
}
