Remarks

NOTE

This overload of the RichEditExtension.Open method determines a document's format automatically, but this process reduces the method's performance. You can accelerate the method's performance by specifying a document's format manually using the overload with the DocumentFormat parameter.

This method tries to find the specified document in a list of already opened documents maintained by the DocumentManager. If the document is found, its instance is opened in RichEdit. If the specified document has not been found in the opened documents, a delegate method specified by the contentAccessorByStream parameter is called. It allows you to manually obtain a steam from which to open a document (for instance, to load a document from a database).
