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.

XP batch script to determine yesterday's date works, except on one particular pc

Asked by TechGuyMike in Windows Batch Scripting

Tags: XP Batch Scripting, Windows XP

I have been using a batch file to determine yesterday's date in yyyymmdd format, then copy a file from one location to another. It works everywhere I've used it, until now. At one particular site the batch file fails to completely execute, aborting after the SETLOCAL ENABLEEXTENSIONS line. When troubleshooting I removed the @echo off line and added a bunch of numbered pause/echo statements so I could see where it's failing, then executed the batch from inside a cmd window so it stays on screen, and it actually closes the cmd window. It appears to not like the "FOR /f ..." line since that's the line that seems to make it abort and close the window.

The system is Windows XP. The entire script is attached for your reference. Thanks in advance for your assistance!Start Free Trial
