Text = "") End Sub Now consider the corresponding VB.If the end user clicks on a different control and Text1 contains an empty string, the Lost Focus event resets the background color to white, then the Validate event cancels the focus shift, and finally the Got Focus event changes the background color to yellow again.
Is there a way to not execute the "Validating" event when the user clicks on the "Cancel" button?
By Dan Mabbutt The first Quick Tip Validation Guide defined validation as "the process of checking whether entered data is what it needs to be for the system to work correctly." And I noted in that article that: Windows form controls that have a Causes Validation property can fire a whole family of events when the focus shifts from the control.
Focus Event Support static property to True: When this property is True, the support library ensures that the Lost Focus event is always fired after the Validate event.
Notice that in the previously described scenario – the end user moves the focus away with the mouse but the control fails to validate – then a pair of Lost Focus/Got Focus events is fired anyway (unlike VB6), but this is seldom a problem.
