Animated GIF ActiveX Control
ucAniGif is a simple example of using twinBASIC to create an ActiveX control usable in both 32bit and 64bit VBA hosts (in addition to VB6 and .NET). tB is backwards compatible with VB6/VBA language, and uses the VBA7 syntax for 64bit support.
It's very simple, you can set the file at runtime or design time; if you set it at design time you can set Autoplay. There's Play/Pause/Stop commands. And a SizeToFit option to scale the image up or down for the control size.
This can be built with the free version of twinBASIC from ucAniGif.twinproj, but the 64bit OCX will then display a tB splash screen when loaded. Of course subscribing to this wonderful project is the best option, but the Releases section has binary builds without the 64bit version splash screen.
NOTE: The OCX build file (ucAniGif.twinproj) requires tB to run as admin; this is because it uses the 'Register project to HKEY_LOCAL_MACHINE' option. This is neccessary for some hosts to see the control, but for VBA only you can switch the option to off and run without admin if need be, but this is not required, VBA will see it regardless.
The code itself is very simple; it's just a thin wrapper over IShellImageData. But of course, using COM interfaces is painful in VBA 64bit without typelibs like my oleexp. tB is not only the only way to build 64bit ActiveX controls for 64bit Office using the same language, it also supports easily defining COM interfaces with BASIC syntax in the project, and has my WinDevLib project available, which allows development with thousands of interfaces and APIs already available.
You can browse the source online in ucAniGif.twin, or import the .tbcontrol/.twin/mDefs.twin files into a tB project to use it there, or play with the test project.

PS - Transparency is respected, but you have to set the control's BackColor manually in this initial version:
e.g.
Private Sub UserForm_Initialize()
ucAniGif1.BackColor = Me.BackColor
End Sub
