i have created a textbox, and if the user have enter an invalid value, the textbox must be able to check whether the value enter by the user is a string or an integer. I have set the CausesValidation to true. If i tried to enter a character, and the msgbox should appear "Is not an integer" but instead i got an error message that says "compile error : Method or data member not found " . I doesn't understand why does this error message keep pop out. Please explain where it went wrong.
Private Sub Text2_Validate(Index As Integer, Cancel As Boolean) If IsNumeric(Text2.Text) = False Then MsgBox "Is not an integer" Cancel = True End If End Sub
