Similar to StreamReader, you can pass the path name of a text file to the StreamWriter constructor to open the file automatically.
Of course, you had the usual set of new features. But the big new advance was the addition of XML file formats. With Officeyou can save your Microsoft Excel spreadsheet as XML and use the file just as you would the binary equivalent. The same goes for Microsoft Word.
Why are XML file formats so important? Because for years, the true power of Excel or Word was locked in binary file formats that required elaborate converters to access.
In this article, I show how to build a PHP Web application that uses these formats to read data into a database from an Excel spreadsheet and to export the contents of a database table to an Excel spreadsheet.
This application is a table of names and e-mail addresses.
To set up the database, create the database using the Mysqladmin command-line tool: You then load the database from the schema file: The user and password authentication you use varies depending on your installation, but the idea remains the same.
First, create the database. Then use the SQL file to create the tables with the required fields. Create the import data The next step is to create some data for import. Create a new Excel file. In the first workbook, call the top row of columns First, Middle, Last, and Email. Then, add a few rows of data to the list see Figure 1.
Data for import You can make the list as long as you like or change the fields however you see fit.
In a production application, you would probably want to read and parse the header line to determine which fields are in which columns and make the appropriate changes to your import logic. Import the data The import system starts easily enough with a page in which you specify the input Excel XML file see Figure 3.
In the first phase, I simply parse the XML data and output it as a table. In the second phase, I add the logic that inserts the records into the database. Listing 3 shows an example Excel XML file. Note the document header portion at the beginning that describes the document and who is writing it, lays down some visual information, lists styles, an so on.
Each page already has an excel template to sort of mirror the wpf.
