MAML Migration: The Next Step in the Evolution of Help Authoring. Are you part of that herd of developers that is used to documenting applications by writing help topics in raw HTML?
Now you might be thinking, "Dave, it's not entirely true that XML documentation is without formatting. Sandcastle Now's probably a good time to introduce Sandcastle. A MAML Example. Reading an Excel spreadsheet into dynamic objects - .NET Development - Gal Ratner. Excel represents documents using Office Open XML (OOXML), a zipped XML based format developed for spreadsheet and chart representation.
In this article I am going to demonstrate parsing an Excel spreadsheet and loading the data into a generic List. OOXML was incorporated into Office in 2007 therefore the following code will not work with older versions of Excel.This is our spreadsheet: In order to read and parse the Spreadsheet we are going to use the Open XML SDK 2.0 for Microsoft Office available for download from Microsoft. The complete SDK includes the DocumentFormat.OpenXml library and some productivity tools that will help you examine the structure of Office documents. Open XML SDK is built on top of System.IO.Packaging so in order to use the DocumentFormat.OpenXml library you also need to import WindowsBase.dll. Let’s begin by loading the correct worksheet into a SpreadsheetDocument ExtractRowsData(data, worksheet, ssTable, cellFormats); } return data; }

NPOI 2.0 series of posts scheduled Recently I had to implement some code to create an Excel spreadsheet/report using C#. The task was: given an Excel spreadsheet template - a .XLS file (with formulas, pivot tables, macros, etc) I had to fill some data in one of the sheets of the spreadsheet and send this modified spreadsheet back to the user requesting such an operation (Excel report). The following attests the need for Excel nowadays: Excel has long been recognized as the de facto standard when it comes to presenting management reports. I had a great time while studying the possible ways of doing what the task asks for. I’ve just experienced the above. Do not use COM automation if you are developing server-side code.
This is the NPOI view page: Updated on 9/22/2010. Macaferi's blog: NPOI with Excel Table and dynamic Chart. A reader of the blog called Zip wrote a comment on the post Creating Excel spreadsheets .XLS and .XLSX in C#.
This is an excerpt from Zip’s comment: … if I add rows using NPOI in C#, rows added under the table won't be automatically included in the table, and my chart is not updated the way I would like it to be. How can I work around this problem? I tried to simulate the problem with a simple spreadsheet and I was getting the same problem stated by Zip, that is, if I added one row just beneath the last row in the table, such added row wasn’t included in Excel’s data table and consequently the chart bound to the table wasn’t updated to reflect the new data. To workaround this problem, let’s consider the following spreadsheet shown in Figure 1: Figure 1 - NPOI with Excel Table and dynamic Chart Using NPOI to insert a new row in the table shown above we do the following: // Creating a new row... 0 is the first row for NPOI. The result is shown in Figure 2:
