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!

Controlling Excel with VBA across several functions

Asked by efedora in Microsoft Access Database, Microsoft Excel Spreadsheet Software, Access Coding/Macros

Tags: , , ,

I am populating a workbook in Excel and drawing 30 or so graphs via Access.

Everything is working fine except I get an error exactly EVERY OTHER time I run the function. 438 "object variable not set"

It has a couple nested functions that work with the spreadsheet, so each function has separate set lines for Excel.Application and the workbook.

When I get the error I debug and see that the Set xl = Excel.application worked fine, but set xlb = xl.ActiveWorkbook failed, and xlb  = nothing.

Here's a little fake sample of what is going on:

sub CompleteReport()
populatetemplate "200745"
end sub

function populatetemplate(yearweek as string)
dim xl as object
Set xl = CreateObject("Excel.Application")
xl.Workbooks.Open ReportPath
xl.visible = true
Dim xlb As Excel.Workbook
Set xlb = xl.ActiveWorkbook

((copy a bunch of records to the workbook))

drawlines 1
drawlines 2
drawlines 3

set xlb = nothing
set xl = nothing
end function

function drawlines(index as long)
set xl = excel.application
set xlb = xl.activeworkbook

((code to generate graphs, fails and shows xlb = nothing on debug))
set xlb = nothing
set xl = nothing
end function

i'm almost certain this has something to do with the say i am establishing references to excel from access, and one of those references is being left open or something so it works on every other run.
