A couple of weeks ago, I began refactoring a report that required major revisions. I wanted to be able to compare the old and new versions side-by-side for a variety of situations.
Here's an excerpt of the original report:
Because of the way I implemented this particular report, the changes I needed to make would require a lot of behind-the-scenes refactoring. However, the report itself should look much like the original version.
What I wanted, then, was an easy way to display the old and new versions of the report side-by-side during development.
I would also be releasing beta versions of the changes as I made them to a small group of test users. I did not want the end users to see the two reports side-by-side. Rather, I wanted them to see only the new report and to see it in full screen.
In other words, I wanted a solution that provided the following benefits:
- For developers, auto-resize the two reports and display them side-by-side
- For end users, show only the new report and show it full screen
- Use the exact same code to accomplish both 1 and 2 above
Here are the two views. On the left is the developer view, showing the old and new version of the report side-by-side. On the right is the production view, showing just the new version of the report in full screen.
Here's the code I used to implement this:
If App.IsDev Then 'Compare the old and new tax certs side-by-side ' (leave this code in place until 6/30/2022 for debugging, ' then delete this code and report object "01_TaxCert_previous") PreviewReport "01_TaxCert_previous", "ControlNumber=" & Qt(CtlNum) FillAccessWindow , , "NW", , 0.5 End If PreviewReport "01_TaxCert", "ControlNumber=" & Qt(CtlNum) If App.IsDev Then FillAccessWindow , , "NE", , 0.5
NOTE: This technique violates one of my many programming axioms:
Thus, I implore you to NEVER leave old versions of code, forms, or reports in place, even if only temporarily...because you WILL forget to remove it.
The future-dated comment I added to my code is intended to account for this. I have no doubt, though, that come 2030, that temporary comment and report will still be alive and well within my codebase.
Here's what else you need to make this work.
