Writing Reg_Multi_Sz to the registry

I need to write an application that prompts the user to input network setting changes, ie: IP address, Gateway and Subnet. the problem I have is all of these value are reg_multi_sz and I have been unsuccessfuly in updating the value in the registry. When I attempt to update the values the (Default) value gets changed and the settings are never applied.

I have searched high and low for information on this. The only thing I found was each value needs to be null terminated with a null terminator and at the end. I just can't figure out how to do this.

Please if there is a second set of eyes that knows what I am talking could you please HELP ;)

Thanks.

Have you tried to make a method like

shared writeMultiSZ (ByVal Argument() as string)

and write it to the registry??

_key = Registry.CurrentUser.OpenSubKey(key, True)
_key.SetValue(key, Argument)

Something like this, I am working on a Class that writes in the registry, but at the moment I didn't work with multisz, the other data type for the registry are simply Objects so...

I guess this can help you.
