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!

VBScript Function to process file in -> file out

Asked by dbbishop in VB Script

I need a function in VBScript that accepts 3 parameters, an input filename, an output filename and a string.
I want the function to open the input file for reading and the output file for appending.
I want to write each line of the input file to the output file with the string prepended to the data, then close the files and return the number of lines written (or read)
Here is an example:
calling the function:
  lc = WriteOutput("c:\mydata\myfilein.txt", "c:\mydata\myfileout.txt", "123456,")
  MsgBox cstr(lc) & " lines written"

If the contents of c:\mydata\myfilein.txt was:
abc,def,xyz
tuv,mno,rts

the file c:\mydata\myfileout.txt would contain (after the call):
123456,abc,def,xyz
123456,tuv,mno,rts

IMPORTANT: If c:\mydata\myfileout.txt already contains data, I want the additional data appended to the file. Thus, if I called the function a second time, with a different input filename and string but same output file, the contents of the string + input file  would be added to the output file.
