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.

Batch file function to search string that is entered by user, for invalid characters...

Asked by rbennett in MS DOS, Windows XP Operating System, Windows Batch Scripting

Tags: , ,

I have limited skills when it comes to bat files, and am not experienced with using loops,
 which I think that is what is needed in this case.

 I am writing a bat file that will take an input string from the user and then act on the string.
 But I need to check that string aginst a list of invalid characters, including spaces which I don't
 exactly know how to add to the list of characters.

ie..
 set invalidlist="`~!@#$^&*()=+[]{}\|;:'",<>/?"
 set invalidchar=" "
 set string=

:start
 set /p string= enter your string
 for loop here check for invalid chars (?)
 if invalid chars are found goto badchar
 
 if not bad chars are found, goto work
 
 :badchar
 echo.
 echo you cannot use spaces of any of the following characters
 echo `~!@#$^&*()=+[]{}\|;:'",<>/?    <---<< also ow can you echo these and get them to show up as output?
 goto start
 
and so on......

   Does this make sense? I guess basically, the user enters a string and presses enter, the function would look at each character
  and compare it with each invalid character and if there is a match there it will error out and make them re-enter a string again.
  if there are no errors found it will continue on.
 
   Thanks,
