Create PowerPoint charts from MS Access queries - excel

Question

I have an Access db to track metrics and "number crunch" data to build PowerPoint presentations. I do about 40 presentations per month, and they are 98% charts.
I run queries one at a time (using SQL statements), take the resulting data and copy it into an Excel template (I made a mock table in this "template" so the chart is already built and formatted), then copy the chart as a picture into a PowerPoint template.
So there is a lot of manual work.
How can I run multiple queries in Access with VBA on the same dataset/table (I have to do sales by quarter, by month, by region, by state, by site and all of these are Top5 aggregate, hence the reasons for the charts), and then send the resulting data to a specific Excel workbook, while defining what goes into what cell range?
If I get all the data into Excel, and have the charts ready to go, is there some VBA that will take the charts from Excel (activeworksheet) and paste them into PowerPoint as pictures in a quad view layout?
Can I do the same thing with an Access to PowerPoint approach and cut out Excel?
I am a novice at best.

You don't need to use Excel at all ! Use MS Access Charts in a report and some VBA code to put them into Powerpoint directly. There is already an example here
One "gotcha" is if you generate graphs in a group ie you design the report with a graph that is inside a group - so when you run the report you will get numerous graphs created.
It is a bit tricky to get hold of each of these graphs and drop them into Powerpoint but here is some code that will take care of it. This works in Access 2003
'Loop through all the controls in this report and pickout all the graphs
For Each c In pReport.Controls
'Graphs initially appear to be in an Object Frame
If TypeOf c Is ObjectFrame Then
'Check the Class of the object to make sure its a Chart
If Left$(c.Class, 13) = "MSGraph.Chart" Then
'Check if this graph must be cloned (required if the graph is in a group in the MS Access report)
If Not IsGraphToBeCloned(pReport.Name, c.ControlName) Then
InsertGraphToPptSlide c, "", pReport.Name
Else
InsertGraphGroupToPpt pReport.Name, c
End If
End If
End If
Next
This will find all the graphs in the report, if the graph is in a group then we call the InsertGraphGroupToPPt function.
The trick here is that we know we have the same base graph multiple times - but populated with different data. So in Powerpoint what you need to do is paste the base graph into powerpoint slides n times - where n is the number of groups and then update the graphs query properties
eg
Function UpdateGraphInPowerpoint(sql As String, OrigGraph As ObjectFrame, Groups As dao.Recordset, GroupName As String, ReportName As String) As Boolean

Since you are a novice, perhaps you should break the task down into parts and automate the parts one at a time. Each step will provide benefits (i.e. time savings) and you can learn as you go.
It is hard to make specific recommendations based upon lack of specific information (what version etc.). That having been said, perhaps a good first step would be to link the Excel tables to the access queries so that the spreadsheets can auto-update every month and you will not have to cut and paste data from Access into Excel. You can do this linking entirely within Excel.
If you are using Excel 2007 click on "Data" in the Ribbon and then click on "From Access".

What you're asking is a lot of work:
Via VBA you'd have to open Excel (Excel Application manipulation from Access) , update your charts (Range manipulation, Data Update) if you have the rights then I would suggest having your pivot charts connected to the Access data and not pasted into the workbook, nevertheless I've been in enough situations where that was not possible. Then you would have to open your PowerPoint presentation and copy from the Excel to the PowerPoint. I've done all of these and know how much work it can save by creating a macro (via VBA) to do this. It's a lot of code.
