Team -

Working on a personal project to help with my sons spelling.

I can't seem to find an easy solution to this so I hope someone can point me in the right direction.

Textbox 1 will hold the correctly spelled word.
Textbox 2 will be typed BUT I want the background of textbox2 to change green if he is on track but turn red when he messes up on a letter.

Basically I need the two boxes to be validated each time he presses a key. I can do the box to box when complete but the trick I am having is how to I have them check as he is typing?

Thanks!

Use the TextChanged event.

Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

        If (TextBox1.Text.StartsWith(TextBox2.Text)) Then
            TextBox2.BackColor = Color.LightGreen
        Else
            TextBox2.BackColor = Color.Salmon
        End If

    End Sub

That works exactly right. Thanks for the .StartsWith, I had never heard of it before!

You just saved me tons of time. I was working with determining lengths and doing trims based on lengths etc. and have the two boxes compare letter by letter but this is MUCH easier.

Thank you again!
