You would have to check if the values are invalid.


Try the IF statement, or the Select Case statement.

vbcode Code:

'Create Error Messege Variable
Dim ErrMsg as String
 
If Year < 1950 or Year > 2050 then
     ErrMsg = "Please enter value from 1950-2050"
else
     ErrMsg = ""
End If

vbcode Code:

'Create errormessage variable
Dim ErrMsg as string
 
select case year
     case <1950 or >2050
          ErrMsg="Please enter a date between 1950 and 2050"
 
     case else
          'set value to "" so no messege
          ErrMsg = ""
          'do nothing, the value is inbetween
end case

I am at work and might not able able to fully answer you.

vb Code:

Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button.Click
'Put code here to get information from the text boxes.
'Also put code here to check the text boxes.
'Put code here to check the Interest to make sure it is >0 and <100, or >=0 and <=100
End Sub

Thank you! I got it!
