Adding two numbers together?

[Dave Kreskowiak]

This is the kind of problem you get when using controls to store your game state. DON'T DO THAT! Controls are there to SHOW and EDIT your data, not to hold it for you. Maintain your values (state) in a class, or other appropriate storage, such as a structure, designed for the purpose. The controls can then get their values from the game state storage. Doing this also frees you from parsing or casting data back and forth.

Thanks Ralf for taking the time to answer will look in to what you suggest.

Well excuse me Dave for being the fool, only just started with VB so will go away and try to decipher what it is you are trying to tell me.

Well here's what I came up with after reading some tutorials it works so I'm happy but is it correct?

Static counter = 0
Dim labels = {Lbl_roundscore1, Lbl_roundscore2, Lbl_roundscore3, Lbl_roundscore4}
Dim totals = {Lbl_total1, Lbl_total2, Lbl_total3, Lbl_total4}
labels(counter).Text = Txt_input.Text
Dim num1 As Single = Val(labels(counter).Text), num2 As Single = Val(totals(counter).Text)
Dim Sum As Single = num1 + num2
totals(counter).Text = Sum.ToString
Txt_input.Text = String.Empty
counter = If(counter = labels.Count - 1, 0, counter + 1)

:omg: oO ... I wrote cast and I meant convert - but I think it's clear what I tried to say ... ;)

"Dim Sum is Single". Poor Dim Sum :D How would you define "correct"? If it works, it works. It's not nicely parsing and displaying error-messages if someone enters a text, or Roman numerals.

Hi Eddy, Yes it works and not displaying error messages if you enter text or roman numerals, so for me that's OK. By correct I guess I mean is it good coding or is any code good if it works?

"Good" is in the eyes of the beholder; I prefer to see error-handling when getting user-input. If you don't mind, who am I to say it is wrong? Are you sure that "static" is what you want, or do you just need some int? And again, you're using the UI to keep a current "state"; meaning, you're abusing the controls for something that should be a separate variable. ..and no documentation. No single comment. I'd be more impressed if the amount of totals were variable, but impossible to say if that's logical from a user-viewpoint. Depends on what the code is required to do.

Are you sure that "static" is what you want, or do you just need some int? Not sure what I want only started using it 2 days ago. The program is only for me when playing a game with family that scores each round and has a running total. It's so small it doesn't need comments so is it good? It does what I want without errors it's for personal use so I guess it's good. Thanks to all who have contributed.
