in a visual basic app how do I make it go through a list of options and choose the first one that applies?

Question

I am making an application in which one button click must run through a list if options like this
>If T1.Text = "Y" And T2.Text = "Z" Then T3.Text = "X"
>If T1.Text = "Y" And T3.Text = "Z" Then T2.Text = "X"
>If T1.Text = "Y" And T4.Text = "Z" Then T7.Text = "X"
and if more than one applies only choose the first one that applies on the list and not carry out more than one command

Answer 1

Dim X
X=0
Do While X=0
If T1.Text="Y" and T2.Text="Z" Then
T3.Text="X"
X=1
End If
If T1.Text="Y" and T3.Text="Z" and X <> 1 Then
X=1
T2.Text="X"
End If
If T1.Text="Y" and T4.Text="Z" and X <> 1Then
X=1
T7.Text="X"
End If
Loop

Nice and easy.

Answer 2

Or, something like this would work... if you have multiple things to do other than just set T3, T2, or T7.


Public Sub Button_Click()
If T1.Text = "Y" And T2.Text = "Z" Then
HandleFirstCase()
ElseIf T1.Text = "Y" And T3.Text = "Z" Then
HandleSecondCase()
ElseIf T1.Text = "Y" And T4.Text = "Z" Then
HandleThirdCase()
End If

End Sub

Private Sub HandleFirstCase()
T3.Text = "X"
End Sub

Private Sub HandleSecondCase()
T2.Text = "X"
End Sub

Private Sub HandleThirdCase()
T7.Text = "X"
End Sub

Answer 3

try using elseif

>If T1.Text = "Y" And T2.Text = "Z" then T3.Text = "X"
elseIf T1.Text = "Y" And T3.Text = "Z" thenT2.Text = "X"
elseif If T1.Text = "Y" And T4.Text = "Z" Then T7.Text = "X"

Answer 4

If ((T1.Text = "Y") And (T2.Text = "Z")) Then
T3.Text = "X"
ElseIf ((T1.Text = "Y") And (T3.Text = "Z")) Then
T2.Text = "X"
ElseIf ((T1.Text = "Y") And (T4.Text = "Z")) Then
T7.Text = "X"
EndIf
