There’s a ProgressLabel, a 228×24 DecorativeFrame, and inside that Frame control, a ProgressBar label using the Highlight color from the System palette. The solution is implemented across two components: a form, and a class module. This version is better though, be it only because of how it deals with cancellation.

This solution is based on a piece of code I posted on Code Review back in 2015 you can find the original post here. We want a modal indicator (so that the user can’t interfere with our modifications), but one that doesn’t run the show: we want the UserForm to be responsible for nothing more than keeping its indicator representative of the current progress. So, what’s the real solution then? A Reusable Progress Indicator If you want to reuse that code in the same project, you’re out of luck – either you duplicate the “indicator” code and reimplement the other “worker” code in another form’s code-behind, or the form now has “modes” and some conditional logic determines which worker code will get to run: you can imagine how well that scales if you have a project that needs a progress indicator for 20 features. That is the problem: if you want to reuse that code, in another project, you need to carefully scrap the worker code. The form is running the show – the “worker” code needs to be in the code-behind, or invoked from it. If we only care to make it work yesterday, a “Smart UI” works: we get a modal dialog, so the user can’t use the workbook while we’re modifying it.

#MVP EXCEL VBA TUTORIAL UPDATE#
Modeless Progress IndicatorĪ commonly blogged-about solution is to display a modeless UserForm and update it from the worker code. Rubberduck has an inspection that specifically locates these implicit references though, so you’ll do fine. It’s critical to understand that the user can change the ActiveSheet at any time, so if your long-running macro involves code that implicitly (or explicitly) refers to the active worksheet, you’ll run into problems. 'if ScreenUpdating was off, toggle it back off: 'make sure the update gets displayed (we might be in a tight loop) If Not isUpdating Then Application.ScreenUpdating = True 'we need ScreenUpdating toggled on to do this: Public Sub UpdateStatus(Optional ByVal msg As String = vbNullString) You could use a small procedure to do it: If the macro is written in such a way that the user could very well continue using Excel while the code is running, then why disturb their workflow – simply updating the application’s status bar is definitely the best way to do it. You need a way to report progress to your users. Oh, it’s as efficient as it gets, you’ve put it up for peer review on Code Review Stack Exchange, and the reviewers helped you optimize it. So you’ve written a beautiful piece of code, a macro that does everything it needs to do… the only thing is that, well, it takes a while to complete. TWhen to Use Constants and/or VariablesT.

It also has a companion workbook demonstrating the effects of scope in Excel VBA.Īnd keep your eyes out for an introduction to Debugging that is now a work in progress.
