Having trouble with the ToUpper method
Ok, im in a VB class and for homework my professor gave the class an assignment where we needed to detect what the middle character of a 5 character string was and if that letter was a b or B then a label would display the word Blue.
So far my code looks like this Code:
Dim item As String item = itemTextBox.Text If item.Substring(2, 1) = "b" Then colorLabel.Text = "Blue" End If everywhere ive tried placing the .ToUpper Method has resulting in the code not working for "b" or "B" despite there being no error's in the code. I next tried Cases instead of If statements and used this code Code:
Select Case item.ToUpper.Substring(2, 1)
Case "B"
colorLabel.Text = "Blue"
End Select
and this code works perfectly for "b" and "B" as the center character in the 5 character string. However i'd like to do this using an If statement. Is it possible? If it is then can someone please point me as to where i need to place the ToUpper method in the first code i posted to make it work for "b" and "B"? Thanks.

You if doesn't work when you add ToUpper() because a "b" would become "B", so it can't possibly equal "b". Your case works because you are doing ToUpper(), and comparing it to "B".
