watin - saving a generated excel sheet

I have a Watin script that logs into a site and generates a report in excel format. I'm having a really hard time saving the generated excel file. I thought my answer was using the GetActiveObject method in interop services. I don't get an error using that, but it doesn't seem to find it either.

More info if it's any use: The original browser window remains in the background and the excel sheet generated has a name of "xxx.aspx". It's NOT in a browser window as it shows up as excel in the task bar.

Any help attaching to the new excel window would be greatly appreciated 开发者_Python百科because I'd like to save it to disk.

WatiN only automates the browser so once the file is open in Excel WatiN is no longer helpful to you. You might want to ask this question without reference to WatiN since it is strictly a .NET/interop scenario. Here is a link that might be helpful to you: http://support.microsoft.com/kb/316126
