xls

I'm trying to use POI.APACHE to edit excel files in java. I have to convert a .xls to .xlsx because I need to send the file to sharepoint. Thats why it just can't be renamed with a different extension. How would I go about this? I couldn't find any examples on their site. Thanks import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.util.Iterator; import org.apache.poi.hssf.usermodel.HSSFWorkbook

I'm currently learning C#, and recently I've learned about the MVVM design pattern for WPF.

I use Spreadsheet_Excel_Writer to generate .xls file and it works fine until I have to deal with a large amount of data. On certain stage it just writes some nonsense chars and quits filling certain columns. However some columns are field up to the end (generally numeric data) I'm not quite sure how the xls document is formed: row by row, or col by col...

I think there is no need in all of my code here are some essentials $filename = 'file.xls'; $workbook = & new Spreadsheet

I need to convert an .xls file to text, i dont need it formatted in any way. The file is filled with productids like PN-5098P, which i will preg_match_all to get. What is the simplest solution? I tried simply opening the file in a regular texteditor, the ids are not showing, so i guess i need some kind of binary converter?
