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!

However, we're offering this treeview to you at no cost. You get an unrestricted license for use in any VBA project you like. You're free to modify any part of the code at will.

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.

‘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,
your treeview save me... but i have a problem when i change the picture to display: sometimes i can't change bmp. there is a method to load picture by code?

Thanks!!!

Hi Silvy,
You can add new images to the treeview's Images collection during runtime with mcTree.ImageAdd(pic, sName). The 'pic' object could, for example, be returned with VBA's LoadPicture.

Change the node's ImageMain or ImageExpanded property to the unique name you included with ImageAdd. Then, force the node to update and display the new image with cNode.ImageUpdate.

See ImageAdd and ImageUpdate in the demo's documentation in the clsTreeView and clsNode sheets respectively.

Is it possible to late bind the treeview control code?

I haven't seen an example of the form object being late bound, to avoid setting the reference directly.

Hi Trevor,

What exactly do you have in mind? Given that the classes are in your project I see no benefit of late-binding, as there isn't anything to reference?


Comment by: Trevor (30-3-2022 10:21:00) deeplink to this comment

Sorry I wasn't very clear - You have to manually set a reference to the Ms Forms Object Library in the VBA IDE.

If you open a database on another machine that doesn't have this reference set it obviously doesn't work. Not all end users would be comfortable setting this reference, or if distributing an accde would be able to if they only had a runtime environment?


Comment by: Peter Thornton (30-3-2022 11:55:00) deeplink to this comment

Hi Trevor,

The MSForms reference must be set at design, it wouldn’t work with late binding for various reasons.

Normally there should be no problem to distribute with the reference, including in an ACCDE. Your Access users should have the runtime which is included with Office.

Slightly related, although the demo illustrates adding a userfom with startup code on first use, in practice it should be fine to distribute with the userform already added.

Great product! But I was wondering if there was a way to get the MouseDown event from the tree to allow adding a popup menu on a right mouse button click on a node?

Hi Steve,

There are some examples in these comments on how to add your own events to the control. Here is one: https://jkp-ads.com/Articles/treeview.asp?AllComments=True#19378
