Hi,

For a static icon, sending the WM_SETICON to the UserForm window is the standard way and it is straightforward. However, for an animated icon, we would need to use multiple images\frames and periodically alternate them in a timer procedure or in a loop. This can become quite tedious and has a performance hit.

Here, I am using an animated gif alternative... Animated gif files are easy to obtain and share and are ready to use.

2- This is how to use the above class for setting the gif pseudo-icon: on the UserForm.
UserForm Module:
VBA Code:
Option Explicit

Private IconClassInstance As IconClass

Private Sub UserForm_Initialize()
    Set IconClassInstance = New IconClass
    IconClassInstance.AddAnimatedIcon Me, ThisWorkbook.Path & "\1.gif"
End Sub

For better looking icons, try using transparent gifs.

Tested on excel 2016 64bit , Windows 10 64Bit
 
Thanks everyone for testing the codes and for giving me feedback and happy we could find a nice solution in the end (y)

Excel Facts

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
Small update to allow for displaying gifs directly from web URLs (as opposed to just from disk files).

UPDATE
