@Z I'm using Access 2010 as well. Inserting the control worked just fine. My problem came in the VBA editor when trying to declare a variable as a treeview as Smiley had in his video
- Dim tv As MsComctlLib.TreeView
I assumed that this meant that I needed the MsComctlLib file. I already had the reference to the Microsoft Office 14 Object Library selected, but not the Microsoft ActiveX Dataobjects 2.1 Library. However, adding that later didn't fix it.
I GOT IT! I found an article that said that Windows 7 x64 (what I have) stores its 32 bit drivers in the Windows\SysWOW64 folder (my office installation is 32 bit). In the References window, I browsed to that location, selected the MsComctl.ocx file which turns into the Microsoft Windows Common Controls 6.0 (SP6) reference. I selected it and it now works.
@ NeoPa No Smiley doesn't tell how to get a hold of the library. I might add a comment to his YouTube video and suggest explaining that.
One more question that might be a little off subject, but does anyone know how to add this reference when the user only has Microsoft Access Run-time 2010?
