Comentários

This method is called when a component is first added to a data flow task. It is similar to a constructor and is the method that initializes a component. Components should add their inputs, outputs, and custom properties during this method.

The base class adds synchronous IDTSInput100 and IDTSOutput100 object to the ComponentMetaData.

Exemplos

public override void ProvideComponentProperties()
{
    // Reset the component.
    base.RemoveAllInputsOutputsAndCustomProperties();
    IDTSInput100 input = ComponentMetaData.InputCollection.New();
    input.Name = "Input";

    IDTSOutput100 output = ComponentMetaDAta.OutputCollection.New();
    output.Name = "Output";
    output.SynchronousInputID = input.ID;

    IDTSCustomProperty100 property = ComponentMetaData.CustomPropertyCollection.New();
    property.Name = "RuntimeVariable";
    property.Description = "Identifies a Variable in the package.";
}

Public Overrides Sub ProvideComponentProperties() 
 MyBase.RemoveAllInputsOutputsAndCustomProperties 
 Dim input As IDTSInput100 = ComponentMetaData.InputCollection.New 
 input.Name = "Input" 
 Dim output As IDTSOutput100 = ComponentMetaDAta.OutputCollection.New 
 output.Name = "Output" 
 output.SynchronousInputID = input.ID 
 Dim property As IDTSCustomProperty100 = ComponentMetaData.CustomPropertyCollection.New 
 property.Name = "RuntimeVariable" 
 property.Description = "Identifies a Variable in the package."
