This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes).

View 3 RepliesI have a requirement that the user will need to import a list of ID's to the asp.net website from their own spreadsheet. I will provide a button 'btnImport' which will use an OleDbConnection to read the spreadsheet and pull in the id's. I have that working fine in my local dev environment. My question is, when this app is running on a production server, will the user have to upload her spreadsheet to the server first? Or do I need to provide code that will find the file on her machine? I'm not sure how this part of it works.

View 1 RepliesPossible Duplicate: Create Excel (.XLS and .XLSX) file from C#
I have some code that generates a zip file that contains multiple CSV files and streams it back to the user (no file is saved on the server). However, I want to create an excel workbook instead (can be traditional xls or Office Open XML xlsx format) with each CSV 'file' being a spreadsheet.
How can I do this, without resorting to Office Automation on the server or a commercial 3rd party component?

View 2 RepliesI have a datasource of an excel spreadsheet provided by a customer. The data is biographic information about clients. The last row contains a web link to view an image of the subject. I have open access to download the spreadsheet and can click each image to view the full jpg in IE.
What would be the best method to loop through the image link to deposit the image into a central file location? The datasource contains 50K subjects and is updated monthly, this is why a manual process is out of the question.
I'm trying to upload an excel spreadsheet using the FileUpload control, read the excel sheet using OleDb connection, and save the strings onto a sql server database.Then, I'm trying to read each string in another method.My web app is currently hosted on the network on my local box, and using savePath= @"C:desktop" like I had it previously wasn't working, so I figured using a sql server database would work for being able to save the file and open it again... but I'm getting confused on how to do so, so i tried using my old savePath but it's not working anymore. So... I'm really at a lost on what to do and how to fix it.

On an .aspx page in a web site I need to retrieve some data from a sql server database and, instead of displaying it in a Gridview, I need to put the data in a spreadsheet and present the user with a Save As dialog.
I'd prefer to do it without using the Office / Excel / Interop com object - so, from what I've read so far, I can do this by returning XML data from SQL Server?
Normally I get data from SQL Server and populate a dataset or datareader with it - and then use this as the Datasource of a GridView.
If I run this in SQL Server ...
Code:
SELECT UserID, UserName FROM tblUsers FOR XML Auto, Root('Users')
It produces this ...
Code:
<Users>
<tblUsers UserID="1" UserName="Steve" />
<tblUsers UserID="2" UserName="Andrea" />
<tblUsers UserID="3" UserName="Zebedee" />
</Users>
So, first question - how do I get the data from SQL Server into my .aspx page? (All data access is done with stored procedures - so, from my data access class normally I create, for example, a SQLDataReader and populate it by calling a stored procedure. What object would I populate with the results of a stored procedure that contains a select statement with 'FOR XML Auto'
Then, assuming I get the XML into the .aspx page - how do I get it into a spreadsheet so that there are two columns called UserID and UserName and 3 rows with 1, 2 and 3 in the first cell and Steve, Andrea and Zebedee in teh second cell?
