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

Content

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 to develop a custom-made Treeview "control", that only uses the native Office forms controls. A couple of weeks after I started building this 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 (former) Excel 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!

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.

‘Pro’ Treeview and ListGrid VBA controls

If your project needs more features and/or better performance than our free treeview, or if you need a listgrid control you've come to the right place as well.

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 Hervé

If using FullWidth, in the declarations try increasing the mcFullWidth value, for example

Private Const mcFullWidth As Long = 1000


If not using FullWidth I don't think the truncated issue would occur, but let me know if that's not the case.

Yes, with variable sized or 'too large' images use of fmPictureSizeModeZoom is a good solution.

You might want to change mcIconSize As Long = 12 (12 is good for 16x16 pixels in a 100% display)

FWIW the Pro Treeview handles different screen display % sizes much better, and doesn't use a fixed width with mcFullWidth which can extend labels unnecessarily to the right of the treeview (albeit not visibly). Optionally the pro automatically resizes images for larger display settings.

Hi, there is a problem with treeview in access form when treeview is a subform and HighDPI mode is enabled on msaccess.exe. It seems that subform unexpectedly un-pin from form. Is there any issue resolved with that?

Hi Yaro

It’s true our original free Treeview doesn’t handle non-standard DPI particularly well cosmetically, however I don’t think we’ve ever received any reports of what you describe.

If this occurs with the original/unmodified demo please describe the steps to reproduce. If it only occurs in your project, if you can email me a stripped down version with instructions I’ll have a look.

Excellent update to the Treeview control, Jan.

How would you suggest handling different screen resolutions to provide a more consistent display of icons.

For example, I have a high resolution laptop (3840 x 2400), but also need to use the Treeview on screens with a far lower resolution. On high resolution screens, the icons are tiny.

Would you suggest storing several icon sizes and swapping between them based on the screen's resolution (and zoom level) or something else perhaps?

with thanks

Hi Marcus,

I suggest to try adding one higher resolution icon to an image control with the image control set to zoom. Then create multiple copies of various sizes of that control, simply in design mode on a temporary userform. That way you can play with the picture related settings of the image controls to see what comes out best on various screen sizes. Your challenge is going to be to reliably get the resolution of the screen on which your firm is shown.

Hi.

Please tell me what is new on build 26.5. I can't find any information on excel file about this build.

Thank you very much.


Comment by: Jan Karel Pieterse (15-1-2023 12:09:00) deeplink to this comment

Hi Filipe,

To find out what is new, look for "Narrator" and/or "reader". It is a temporary textbox which we added to make sure screen reader software understands the treeview and reads out the caption of the active node after you select it. This is an important accessibility feature for people with eye sight issues.

Thank you very much!
Great addition to the treeview control.
Keep the outstandin work.

Best Regards.
