Requiring Input

[MDEnt]

Wondering if anyone has any sample code that would show how to require a user to enter text - meaning they cannot proceed if they do not enter something.

I am using the Dialogues library to capture text - below is a snippet where text is to be entered. Problem is, if they just hit the OK button and don't actually enter anything - it proceeds anyhow.

Dim Id As InputDialog
Id.InputType = Id.INPUT_TYPE_TEXT
Id.Input = ""
Id.Hint = "a color"
ret = Id.Show("Some filler text", "Please enter your favorite color.", "OK", "","", LoadBitmap(File.DirAssets, "icon.jpg"))

Thanks.

If you put the Id.Show method inside a Do While loop you can check to see if something has been entered:

Do While Id.Input = ""
ret = Id.Show("Some filler text", "Please enter your favorite color.", "OK", "","", LoadBitmap(File.DirAssets, "icon.jpg"))
Loop

TY - I figured some sort of loop would do the trick!
