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!

Excel file is locked for editing, but Excel is not anymore in the processes list!

Asked by cdebel in Programming for ASP.NET, Microsoft Visual Basic.Net

Tags:

I'm developping an application using ASP.NET and VB.NET.  It use Office 2003 Interop's to open a report template of a report file, then after the job is complete, it update the report and place it in a specific folder under the root (/reports).  The file name contain the date & time when the report was generated.  Then, it send this report to the user who generated it.

When the user get it by email, everything is fine.  He can open the excel file without any problem.

On the server, there's some problems.  If i try to open the report it will tell me that the file is locked for editing and giving "read only, notify, cancel" choice.  So it mean that the file is still in use... but i've checked, there's no EXCEL in the Processes list.   (Can't delete the file also of course).

Any idea of what i'm doing wrong?

Anyone have amethod to Save & Close an Excel file, then close Excel properly?

Here's my code:
