Time Format Validation

User Entering the Time Value in the Masked Textbox

For Example

User Enter Time like 08:00 (HH:MM)

User Enter Time like 28:00 (HH:MM) , Textbox should not accept this value. Because it should accept from 00 to 23 (HH) and 00 to 59 (MM).

How to do this.

Have a look at the Validate Event - you can test the value in this event and correct it or error appropriately (depending on what user experience you would like)

Private Sub txtDate_Validate(Cancel As Boolean)
    If Not IsDate(txtdate.Text) Then
        'fix it here OR
        Cancel = True 'don't allow the input
    End If
End Sub

Why not use the DateTimePicker instead of the MaskedTextBox? DateTimePicker was specifically designed for allowing the user to enter time values. Set the CustomFormat to "HH:MM"

I don't know how to get the masked textbox to range check the values as it can't be checked using a format string. You can however use the IsDate() and/or CDate() functions to check and convert to a valid date/time.

?isdate("08:00")
True
?cdate("08:00")
08:00:00 
?isdate("28:00")
False
