OK. I've done that as well, but wasn't connecting that to Nathan's query. I was thinking of bringing binary data into a document, like into cells of a spreadsheet, e.g., code that brings in data from an RS 232 serial port and places values into a cell, and then triggers a recalc/chart update, etc. -Rob > > > -- > Andrew Pitonyak > My Macro Document: http://www.pitonyak.org/AndrewMacro.odt > Info: http://www.pitonyak.org/oo.php >
