    Hi all


    I've just started building an app for Windows Phone in C# using Visual Studio Express 2013. This is just a spare time thing and completely for learning and something to do.


    What the app will do is basically take two numeric inputs from separate TextBoxes. I've a table for cross referencing, with columns and rows. I want to take the inputs and get a value from the table.


    So, if Input 1 = Blue and if Input 2 = Yellow, then I'd get Green out. But if Input 1 = Red and if Input 2 = Blue, then I'd get Purple.


    I don't want someone doing this for me or anything, just an idea of what I could do. I'm hoping there's an easier way of doing it than writing a very long if() statement!


    Thanks

    No no, you don't want a long IF statement. I'm not really sure what you're asking here though. Create a local database and create the lookup table which stores the two inputs, and the output it should give.

    You'd then have a function which takes the two inputs and queries the table to return the output. This would be in a data access layer class, and would be called by either your UI event, or business layer function. It would obviously need to be asynchronous to prevent the UI from locking up.

    Brilliant, thanks for that. I was wandering around the developer forms on stack overflow and Microsoft but I wasn't sure what the question I was trying to ask was! This'll put me right.

    ...or just create a utility class that encapsulates the inputs and use that as a key into a hashtable.
