FieldClass Events
There are the same events for FieldClass objects as for FieldType objects, see there for a description of the
events. The only additional event for the
FieldClass object is a OnFieldClassDeleted event, which is not
used in the Ascent Capture version of DOKuStar Validation.
You will use
FieldClass events when you want to handle all fields of a certain FieldClass (= Ascent Capture
FieldType) alike. For example, if you have several date fields, you might define them in the Ascent Capture
Administration module in a way that they all belong to the same Ascent Capture
FieldType MyDateType. You
will then define a
FieldClass in the script accordingly and use its OnFieldChanging event to do checks:
Dim WithEvents myDateType As FieldClass
Private Sub Application_OnProjectLoaded(ByVal App As Application)
Set myDateType = App.Project.DataSet.Schema.FieldClasses("MyDateType")
End Sub
Private Function myDateType_OnFieldChanging(ByVal Field As Field, ByVal SubField As Field, ByVal
VerifyEventArgs As VerifyEventArgs) As Boolean
myDateType_OnFieldChanging = True
If DateCheck(Field.Value) = False Then
MsgBox "Date is invalid"
myDateType_OnFieldChanging = False
End If
End Function
Private Function DateCheck(strDate As String) As Boolean
' Do Date Checking, return True or False
End Function
