For general moving Access into Excel with code - this is still my favorite:
http://www.btabdevelopment.com/ts/default.aspx?PageId=10
Once the Excel document is open
Right click in the Ribbon (menu) and Customize the Ribbon
On the Right-Hand list box (Customize the Ribbon

the Developer box is unchecked - check it
Now the menu has "Developer"
When Developer tab is open, choose Record Macro
On the upper Left-Hand cell (just above 1 and just to the left of "A") choose
This selects the entire Worksheet
Put the mouse cursor just between the line between A | B the cursor will change to show the line is chosen - Double Click
Now, Stop Recording (menu)
Double click on the Macro box - Sub Macro1 will open and display
Cells.Select
Cells.EntireColumn.AutoFit
While the Macro Recorder won't take care of advanced programming, it will provide basic guidance for the Excel Object, Properties, and Methods.
This code can typically be placed back into the Access VBA. It will just need the object reference to Excel to run from there.
Example:
Dim MyExcel as Excel.Application
See code link above to open excel from Access and then run this extra:
MyExcel.Cells.Select
MyExcel.Cells.EntireColumn.AutoFit
I didn't mean to steal any thunder. They just gave me a new Xenon computer with SSD Hard drive, so I am re-setting up all of my Office applications. Including the Menu item for Excel Developer.
The Company Web Troll Monitor now blocks MZTools. Lucky I kept the last download. For a while, I was wondering if I could get to Bob Larson's site mentioned above.
