An MSForms (all VBA) treeview
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:
- Compile errors due to a difference in how the control libraries are registered in 32 bits Windows' System32 and 64 bit Windows' SysWOW32 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.
- 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 was tested (and works) on 64 bit Office. It also works on MAC office. Tested applications include:
Excel 2010 (64 bit)
Excel 2011 (MAC Office)
Excel 2013 (32 bit)
Access 2010 (32 bit)
Access 2010 (64 bit)

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'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.
You use this control at your own risk: The authors accept no liability whatsoever for any damages which may arise due to the use of our treeview.
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:
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.

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.
