The Error Provider is a Win Forms control that allows you to show a red exclamation mark with an error message tooltip next to a control.

It's really useful when combined with the above data validation method.

I just discovered that the Masked Text Box control allows you to set the type of data which should be entered in the control and helps you do the validation of that data when necessary.

The trick is to set the Validating Type of the Masked Text Box control to the type of data you want to get from the user.

The example shows us setting the type of data which should be entered into the text box and then subscribing to the corresponding event.

In that event handler, we check if the input is valid (don't know what all that does, but it works - play with it) and, if so, cast the value to the correct data type in order to use for some purpose.

Message is generally the same as the Message parameter of any exception that has been thrown).

Quant au Tool Tip, je ne connaissais pas avant que tu m'en parles. Text ' "24/07/" & Annee & " " seuilete = CDate(iddate) '---------------------------------------------------------------------- iddate = Masked Fin. Text = "25/07/2014 " End Sub Private Sub Button1_Click(sender As System. To String("yyyy")) 'année en cours iddate = Masked Debut.Note: The Masked Text Box control does not support multiline configuration or undo functionality.The following table lists common properties on the Masked Edit control and gives their equivalents on Masked Text Box.
