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!

comparing records in a database

Asked by npepper in Delphi Programming

Tags: comparing, findkey, records

Before i start thanks to the person who kindly assisted me with my last question.

I am trying to write a procedure that uses findkey to locate a record that part is ok, i then need to however compare the fields with the last record i went to and if there is a difference perform another procedure.

I am able to use findkey and assign the fields i need to compare to variables.  However i need to be able to compare these variables to the last record i did findkey on.

procedure Tproductionfrm.M1Pending; {checks for pending jobs in schedule}
var
  IsColorChange: Boolean;
  IsEndOfRun: Boolean;
  ColorToTest: String;
  ProductToTest: String;
begin
  IsColorChange:= False;
  IsEndOfRun:= False;
  with scheduler.SchT do
     begin
        Open;
        Edit;
        First;
           if FindKey(['Machine 1', 'P']) then {Pending}
           begin
              ProductToTest:=scheduler.SchT.Fields[3].AsString; {product for selected record}
              ColorToTest:=scheduler.SchT.Fields[4].AsString; {colour for selected record}
           end;

     end;
end;

This is the basics at the moment and i have yet to perform any comparison.

any clues?
