Form validating event vb net Sex chat online free without signup or credit card

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? End Sub Private Sub Button1_Mouse Leave(By Val sender As Object, By Val e As System. Mouse Leave b Validate Text Box = True '// Enable Validation. End Sub Private Sub Text Box1_Validating(By Val sender As Object, By Val e As System.

Truly, Emad Public Class Form1 Private b Validate Text Box As Boolean = True Private Sub Button1_Mouse Enter(By Val sender As Object, By Val e As System. Mouse Enter b Validate Text Box = False '// Disable Validation. Msg Box("Text Box Validation was Canceled") '// for testing. Validating If b Validate Text Box Then '// validating code here.

Printing Public Class Main Class Shared Sub Main() Dim form1 As Form = New Form1() Application. Initialize Component() 'Add any initialization after the Initialize Component() call End Sub 'Form overrides dispose to clean up the component list.

New() 'This call is required by the Windows Form Designer.

You should always use the Validating event, it was made to support validation.

If not to prevent the focus change then at least for the Causes Validation property.

Private Function Valid Email Address(By Val email Address As String, By Ref error Message As String) As Boolean ' Confirm there is text in the control.

You can use it to make sure that the user has entered something in a Text Box control.

The event handler receives an argument of type Event Args.

When you change the focus by using the keyboard (TAB, SHIFT TAB, and so on), by calling the Select or Select Next Control methods, or by setting the Container Control.

However, for code readability, it would make sense to place all validation code in the Validating event.

So, which is the better option, in terms of both efficiency and industry-standards?
