The new 5.1.0 dll shows the workbook.open method as obsolete, and says I should now use Workbook(stream,loadoptions). However, intellisense does not give me any clue as to what options I have, and in fact doesn't even recognize that method. The documentation on the website also shows the old method as obsolete, but I can't find any reference to the new method. The examples still show workbook.open.
The save also changed a bit, but intellisense does show the new format and it works ok.
Please explain how to use the new method to open a workbook.
