Remarks
The Validate method of a component is always called by the data flow task prior to execution. However this method can be called at any time. When the method is called, the component will check the configuration of its inputs, outputs, custom properties, and column collections to verify that the component is properly configured. Most components will raise OnError and OnWarning events when validation errors occur. These events provide additional information on the problems with the component.
The following table describes the error values of the DTSValidationStatus enumeration.
| Status | Description |
|---|---|
| VS_ISBROKEN | Indicates that the component is not configured correctly, but that it can be repaired by modifying properties of the component. |
| VS_NEEDSNEWMETADATA | Indicates that the validation errors can be fixed by the component in the ReinitializeMetaData method. |
| VS_ISCORRUPT | Indicates that the ComponentMetaData is corrupt and cannot be repaired by a call to ReinitializeMetaData or by edits to the component. This is typically caused by editing the package XML directly. |
