The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Bad Excel file generated by PEAR::Spreadsheet_Excel_Writer only on one file

Asked by MichealECooper in PHP Scripting Language, Microsoft Excel Spreadsheet Software

Tags:

I am writing a script that generates an Excel report for download, and I have one test script and one previous Excel report generator on the same server using the same database, but the new script is not working. I can download the Excel file, but when I try to open it, it says that I cannot. Then when I choose the option of Excel repairing the file, I get the data that I put into it, but there is also a message in a box that reads, "Microsoft Office Excel was able to open the file by making the repairs listed below":
"Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted."

The log file reads:
Microsoft Office Excel File Repair Log

Errors were detected in file 'C:\Documents and Settings\micadmin\My Documents\FacProfile_20080710_AdachiJason.xls'
The following is a list of repairs:

Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted.

My other scripts work just fine, and I cannot find a difference. The data is in the spreadsheets, but I cannot turn this over to my users.
