Notes

The Validate method of the component metadata invokes the layout validation routine implemented by the data flow task. This is different from the validation done by a component when the Validate method of the design-time instance of the component is called. When this method is called, the data flow engine:

  • Verifies that the ID of the component is valid.

  • Verifies that the locale specified for the component is installed on the local machine.

  • Verifies that the component has at least one input or one output.

  • Verifies that the input and output column collections are valid.
