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!

Create a log of times that a computer has been turned on and off. Perhaps using event log data?

Asked by rberke in Microsoft Excel Spreadsheet Software, Miscellaneous Programming, Automation

I already have written an excel macro that produces the spreadsheet  shown below.  

Right now, the input to this macro is coming from a .txt file created by a utility for measuring disk temperatures every few minutes  ("hdd thermometer" from http://www.rsdsoft.com/)

For some reason that .txt file does not always get timely updates, so I am looking for alternative sources of time logs that I could use instead.

I am thinking of writing my own program that appends a date/time entry to a text file, then schedule it to run every 10 minutes.
 
But, I am wondering if anybody knows of an existing source of timestamped log data that I can get into excel.
For instance, does anybody know how to read the contents of the windows event logs into an excel worksheet?
Or maybe somebody knows another source for similar time logs? I don't care much if the time logged is "user logged on" or simply "computer turned on", but I have slight preference for "user logged on".

Here is what my spreadsheet currently generates:


8/28/2008 15:21            OFF AT --------------Thursday 08/28/08 03:21:15 PM
8/28/2008 16:19            ON AT ---------------Thursday 08/28/08 04:19:56 PM (00:58:41 later.)
8/28/2008 16:20            on
8/28/2008 16:49            on <5 preceeding "on" records were deleted because they are boring (their gaps were less than 10 minute long)>
8/28/2008 16:56            on      
8/28/2008 16:57            OFF AT --------------Thursday 08/28/08 04:57:15 PM
8/28/2008 17:38            ON AT ---------------Thursday 08/28/08 05:38:55 PM (00:41:40 later.)
8/28/2008 17:43            on
8/28/2008 17:58            on <3 preceeding "on" records were deleted because they are boring (their gaps were less than 10 minutes long)>
