[news.eclipse.tools] Re: NewWindow2 Event and Shell.Explorer OLE

[Terry Heath <theath@xxxxxxxxxx>]

Does anyone know how to affect the output paramters of the IDispatch
events using the Ole?   Specifically for writing out the new Shell.Explorer
Ole object's appropriate values for the NewWindow2 event into the ppDisp
parameter.

Thanks
