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.
Download Example
1- Class code: (Class name; IconClass)
2- This is how to use the above class for setting the gif pseudo-icon: on the UserForm.
UserForm Module:
For better looking icons, try using transparent gifs.
