The EnableDesign method is used to prepare the component for execution in one of two modes: design mode or execution mode. In design mode, which is useful for running the Pipeline Editor, errors are more easily tolerated. Execution mode (the default) is analagous to production mode.
HRESULT EnableDesign(
BOOLfEnable// in
);
<pipeline.h>
<pipecomp.h>
The method returns an HRESULT value.
