I need to access the data of a rather old closed-source application using DDE. Up until now, I was using VBA for the task and it works well. Now I wanted to switch to C# using NDde, unfortunately however, the application doesn't recognize the commands. From the error messages received I gather that the application is confused by the unicode data it receives, it seems to expect 8-bit strings.
Any advice on how to deal with that? Is there some trick to do this with NDde or would it have to be rewritten entirely?
