I have used the info in KB article
http://support.microsoft.com/default.aspx?scid=kb;EN-US;304662 that Cathi mentioned to put an Excel sheet into a winform. It does it by wrapping the xls sheet in a browser control and pointing the URL to the .xls file.
That worked great. I am also trying trying to provide some automation.

My problem is that I cant figure out how to reference Excel for automation.

Does anyone know how I would drill down from the winform to the browser control and finally to the Excel application in order to read values from the sheet and control it?

Thanks,
