Well if we name the controls correctly we could check against any control we like based on their name, this allows us to group controls for specific validation tasks. Controls If Type Of ctrl Is Text Box Then 'check if it should be string If ctrl. Starts With("txt String") Then 'check if its valid value If ctrl. Show("Invalid Input") Exit Sub End If 'check if it should be numeric Else If ctrl. Starts With("txt Int") Then 'validate that it is numeric If Not Is Numeric(ctrl.

Text) Then 'if not show error and exit sub Message Box.

Hi Everyone, In my form there is a "Validating" event on a textbox. Is there a way to not execute the "Validating" event when the user clicks on the "Cancel" button? Show("Please enter Numeric Values for Phone Numbers") Exit Sub End If End If End If Next You can see that for controls where we want string values entering, we name them txt String and for controls where we want numeric values we name them txt Int. Focus() Return False End If 'check if it should be numeric Else If cnt. Starts With("txt Int") Then 'validate that it is numeric If Not Is Numeric(cnt.This is only a simple example and you could take it further by looking at the rest of the control name say txt String Address which would allow you to give more friendly error messages specific to the correct field. Focus() Return False End If End If Next Else If Type Of cnt Is Text Box Then 'check if it should be string If cnt. Starts With("txt String") Then 'check if its valid value If cnt. Text) Then 'if not show error and exit sub Message Box.I do use this on the Text Changed event, because I don't want the user to continue typing if it's an invalid character; the rule checking "eats" the invalid character. Valid = True End If Else Select Case m Check Type Case Check String If m Input Mask. Valid = True End If Case Else '// right now we're only testing for numbers... Public Enum Check Type ct String = 0 ct Real = 1 ct Decimal = 2 ct Integer = 3 ct Byte = 4 End Enum Private m Allow Negative As Boolean = True Private m Allow Null As Boolean = True Private m Check Type As Check Type = Check String _ Private Sub Rule Check Me() '// Rule Checking If Me. Text Length = 0 Then If m Allow Null = False Then Main. Text Box1, "You are required to provide this value.") Me. Length 0 Then 'TODO: Figure out how to cope with input masks!
