I'm developing a web application which has 2 frames.

One frame reads a HTML file and the other reads an excel file(.xls).

When I open this page on IE6 & Excel2007 or IE7 & Excel2003

the excel frame doesn't show any menu and ribbons.

But the combination of IE7 & Excel2007,

the excel frame shows excel2007's ribbon interface.

I want to hide the ribbon interface.

How can I do that

# When I open an excel file on IE7 without frames,

it doesn't show any ribbons.

I want to do this inside a frame.

Please help me...

best regards,
