Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.

Moved from WinXP to Win7 - don't see choice to open file in read only or edit mode


I just recently moved from Win XP Pro SP3 to Win 7 32-bit Pro. I am logging into domain X normally. Our Sharepoint 2007 server authenticates only on domain Y. So I start Internet Explorer with "run as different user" and provide my domain Y credentials. All fine. 

In win XP, after I did this, when I click on an Excel file on Sharepoint, I would get a dialog asking if I wanted to check out and edit or open as read only. 

In win7, I don't get that choice. The file simply opens, and I get a bar at the top which allows me to check out the file if I wanted to. 

How can I restore the functionality I used to have, with the dialog for checking out the file before opening it?

ParameterField batchdate = new ParameterField();
batchdate.Name = "@BatchDate";
ParameterDiscreteValue batchdate_value = new ParameterDiscreteValue();
batchdate_value.Value = Convert.ToDateTime(txtBatchDate.Text);

foreach (TableLogOnInfo tlf in CrystalReportViewer_ClientLetter.LogOnInfo)
tlf.ConnectionInfo = con;
