Passing Data to a Cell in Excel



I have a webpage that is created in Visual Studio 2008 and programmed in C#.

I have a web form that prompts the user to enter a value into a text box.  For now, I do not have any validation on that field (I will be adding that later).

I need to pass the value that the user has entered to cell C1 of the excel spreadsheet (user_info.xls).

I understand that using excel is not ideal, but unforutnately need to try to make this work with the excel spreadsheet.

I do not have any code for this yet, because I honestly do not know how to begin.

The action of poulating the excel spreadsheet will be intialized from the On Click event of a Submit button.

Any suggestions would be much appreciated.

Thank you in advance for your assistance,

Building a Custom Data Grid: Performing Ad Hoc Web Reporting with a VBScript 5.0 Class Object


A flexible, customizable grid for displaying data is a useful tool for ASP developers. It allows Web visitors to customize their view of your data. This article takes the data grid presented in "Ad Hoc Web Reporting with ADO 2.0" by John Papa and Charles Caison (MIND, December 1998) and adds handy features such as a finds feature that supports multiple finds and a mode for adding and editing records. This version also improves response time by allowing asynchronous record download and it componentizes the code so it can be used as a standalone VBScript class object that can be reused in other pages.
