is that possible to prevent modifying the name of an IDTSInputColumn90?

Hi,

I'm building a custom SSIS data flow component and I create myself input and output columns from a custom property of my pipeline component. That's why I don't want the user to modify the name of the input and output columns by using the advanced editor.

Is there a way either to make input/output column properties - at least the name - readonly or to override any PipelineComponent method to throw an exception like we do when we want to prevent the user from adding/removing input/output colulmns with methods like PipelineComponent.DeleteOutputColumn?

Thanks for your help,

David

Have you tried SetInputColumnProperty? The name is a property, but I have vague recollection that you cannot use that method to set the name, and end up having to do it on the IDTSInputColumn90 reference directly.

Can you detect a change, and pick this up in Validate? If you can detect a change you could return VS_NEEDSNEWMETADATA, and then correct the problem in ReinitializeMetaData. Not as proactive as preventing a change, but maybe it is better than nothing?

I've tried SetInputColumnProperty but it is called only for custom properties...and the name is not a custom property.

I any case, like you said, when the user modifies the name of an input column, Validate is called and I can detect the error...

Thanks
