An MSForms (all VBA) treeview for Access, Excel And Word

Introduction

If you have ever used the Treeview control from the "Additional controls" section, then you know what a versatile control this is to show hierarchically organized data. There are a couple of problems with this Treeview control:

  1. Compile errors due to a difference in how the control libraries are registered in 32 bits Windows' System32 and 64 bit Windows' SysWOW64 folders. If you distribute a file that was saved in 64 bit Windows, containing one of the "Microsoft Windows Common Controls 6.0" (The Treeview control is one of them) and with the reference set to "mscomctl.ocx", people using 32 bit Windows will almost certainly have problems. At best it could entail removing both the control and the reference and replacing both, but at worst the user's Excel can crash when trying to load the file and run the app.
  2. The standard Treeview control, like all non built-in ActiveX controls, cannot be used in 64 bit versions of Office.

Especially the second point convinced me it is time to develop a custom-made Treeview "control", that only uses the native Office forms controls. I started building this a couple of weeks ago and after some time I tricked Peter Thornton into helping me with it

The screenshot below shows both our new Treeview (left) and the Windows one (right) side-by-side in their simplest display mode (read on, there are even prettier screenshots further down the page):

In the following pages I'll show what our treeview can do and explain how to put it to use in your own VBA project.

MAC Office and 64 bit Office Compatible!

Our Treeview works in all versions of Excel, Access and Word; from Office 2007 to 2019 and 365, for Windows and Mac, 32bit and 64bit. It also works in some earlier versions though you would need to adapt the demos made for 2007 and later.

Acknowledgements

The basic plumbing and code structure of this treeview control was devised by me. However, without the help of my friend and fellow MVP Peter Thornton, lots of functionality would not have been available now. For that I sincerely thank Peter!

Furthermore, Access MVP Ben Clothier was kind enough to make the necessary adjustments to incorporate the treeview in an Access form

Also: Fellow Excel MVP Ron De Bruin ensured the treeview also works on MAC Office 2011, Thanks Ron!

We do request that you:

And please mention the source of the treeview (including a link to this page) in your helpfile, manual and/or on your about screen.

We're always interested to see how people have implemented the VBA Treeview. So please feel free to send a screenshot with a brief description or relevant details.

Donations

Many, many hours were spent developing this treeview. Although we developed it for use in our own projects, we are giving it away for free!

Nevertheless, we would really be pleased if you actually express your appreciation in a more "tangible" form. So here is a paypal donation button at your disposal:

Download

The Excel workbook contains most of the documentation (on the tabs of the workbook), so I recommend you to at least download the Excel version. The Access version has instructions on its main form (click the "How do I...?" button) on how to implement the treeview in your own projects.

Download the treeview sample Excel workbook (including documentation) (build 026.4, 28 May 2021, downloaded 43.016 times)

Download the treeview sample Word document (build 026.4, 31 May 2021, downloaded 13.781 times)

Download the treeview sample Access database (build 026.4, 28 May 2021, downloaded 34.928 times)

‘Pro’ Treeview and ListGrid VBA controls

The professional version of the treeview control has exceptional performance. Even with tens of thousands of nodes it will load quickly and remain highly responsive. It also has several new features including drag and drop. Timing experiments have shown that the pro version of our treeview outperforms the common controls treeview.

Our new ListGrid combines most of the functionality of the ActiveX Listview and Flexgrid controls with many extra useful features. It is the result of extensive beta testing by some of our treeview users, thanks guys!

The screenshot of the demo below gives an idea of just some of its capability.

Professional ListGrid control

The Pro Treeview and ListGrid are available for 32/64 bit Excel and Access. The Excel version will also work in Mac, one or two features are disabled for Mac but we’re working on it. Unlike our free treeview they are self contained in their own files and designed to work more like real controls.

For more details and if interested in a trial license to try either of these ‘controls’ please contact us:

Please note that the pro versions are paid versions. Pricing available upon request by using the links above (The download files above contain a Word document which also gives more details about the pro controls).

Other controls

Another often used control is the calendar control. This control has the added problem that it has been deprecated with Office 2010 (where we're supposed to use the date picker control). Frankens Team created an all-vba alternative using very similar techniques to what we've done here.

Ron de Bruin created a Date Picker control for MAC Excel.

Hi Peter,

This is exactly what I was looking to do, thank you!

Hi Peter,
I'm using your magic free treeview alternative with Access 2016 64bit

but, how I list only the nodes checked?

Thanks!
Ann


Comment by: Jan Karel Pieterse (30-9-2021 17:26:00) deeplink to this comment

Hi Ann,

Nodes have a property called Checked which has these possible values:
-1 true, 0 false, +1 mixed

mixed is when the node has childNodes and not all are checked.

Hi,

I have tested the free version and created a tree of 197000 nodes.
Upload was done in more than 26 minutes !

I guess pro version works faster.. What will be the gain approximately ?

Thanks


Comment by: Peter Thornton (3-10-2021 19:46:00) deeplink to this comment

Hi Sam,

I'd expect 200,000 nodes to load and fully display in about 5 seconds in the pro Treeview. That excludes time to get the data which, depending on the source, can vary considerably, but that's not directly related to the treeview.

Actually, if it 'only' took 26 minutes for you with our free version you've probably got a modern/powerful system, so maybe less 5 seconds with the pro for you!

You're welcome to try the pro version, just contact us.

Thanks for your wonderful product Jan. I have donated
The only problem I have had is when I copy and paste my MS Access front end, often the reference to fm20.dll gets lost and has to be re established.
Nothing to do with your product of course but writing it in case someone also goes crazy wondering why the references to MSForms are not being found.

Hello,

In the treeview, ONE of the items is listed with a smaller font that everything else!

here is an image: https://i.ibb.co/NV5n26Q/Bad-Font-Size.jpg

Any ideas why this happens and how to fix?

Is there some place in the code I could examine for this problem?

THANKS!

Hi Richard,

I suspect your screen display is set to a non standard size, 125% perhaps. First could you test with 100%. If that works revert to the original screen size and try the next smaller & larger font sizes.

If your original screen size and font size are important to you might try the 'pro' version (contact us). A lot more work has gone into the pro treeview to display font sizes consistently with different display settings. However even with the 'pro' there are some display/font size combinations the odd irregular font size can't be avoided.
