Gets or sets a Boolean that indicates whether packages can be updated when an updated version is found.
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
If extensible objects, such as tasks, Foreach enumerators, log providers, and connection managers are updated, older packages can be updated at load time. For that to occur, the following two properties must be set to true in the application object before loading: UpdateObjects., and
Each extensible object must also implement its CanUpdate property.
The runtime tries to load the old package, and if it finds an older object, attempts an update. The runtime first enumerates all the extensible objects it contains, excluding the Pipeline, which is treated separately and locally. For each object, the runtime then calls CanUpdate on the new objects, passing the ID of the old object. If the new object can update the old one, the old object is passed to the new one by using its Update method, and its XML is changed in place. By default, all extensible objects implement CanUpdate to return false; therefore, the XML that is passed is not updated.
The following code example shows how to enable and disable updates. It sets theto true, prints the value, resets the value of the property to false, and prints out the value again.
Class ApplicationTests Shared Sub Main(ByVal args() As String) Dim app As Application = New Application() Dim updatePkg As Boolean = True app.UpdatePackage = updatePkg Console.WriteLine(app.UpdatePackage) updatePkg = False app.UpdatePackage = updatePkg Console.WriteLine(app.UpdatePackage) End Sub End Class
