' creat a Application object

Hi I am getting an error with the code above. Do I need to add a reference to my ASP.net project?
Error 1 Interop type 'ApplicationClass' cannot be embedded. Use the applicable interface instead. C:\Users\User\Documents\Vi

This solution is only available to members.

You need to declare the variable as Microsoft.Office.Interop.E
Dim app As Microsoft.Office.Interop.Excel.Application = New Microsoft.Office.Interop.Excel.ApplicationClass
Another tip, If you plan to manipulate Excel files, I recommend you to use OleDb (Microsoft Jet 4.0), it have better performance but it's more limited.

What Excel references are you using? may be "Microsoft Excel 12.0 Object Library"?
