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!

Calling MS Excel function XIRR from Access VBA

Asked by awesomejohn19 in Access Coding/Macros

Tags: , , ,

Hello,

I am attaching the code. So basically I found this code "http://packetguy.blogspot.com/2005/06/excel-xirr-and-xnpv-functions.html" and modified it a little bit to fit my needs. I put two msgboxes. First msgbox gives the lrercordset. But it gives it as "1" but it should be at least 33. So I am guessing for some reason the RecordSet is only taking  the first value out of 33. So it calculates XIRR as "0" . I know my sql statement is correct because when I run it on access it gives me all the data I want. But for some reason, recordset is only taking only one value. I will really appreciate if anyone can solve this problem.
Thanks,Start Free Trial
