Animated MsgBox (Added Gif)

[Jaafar Tribak]

Hi dear forum,

Got bored and decided to add some animation to the standard vba MsgBox. It is not going to be of much use to most excel\vba users, but it was fun to code and will add to the MsgBox, some lively aspect that can be used in capturing the user's attention.

Basically, the code simply hijacks the MsgBox and replaces its default icon with the gif of your choice.

Workbook example:
AnimatedMsgBox.xlsm





I am not versed with HTML DOM coding ... In the tests I carried out with various gifs, I could successfully set the backgroundcolor only in some of them. This is in order to match the gif background color with the MsgBox theme for blending.

Unless the gif is a transparent gif, much of the image quality may be affected if the gif has a background color that cannot be set.

Amazing sir, you're the best...
But what I mean is not the image on the userform but the animated image on the MsgBox, what can be set for the size while still displaying the message text because in the MsgBox that you make the animated image display in my opinion small I want to enlarge the size of the animation display. Can you tell me which part of your code to enlarge the display of the animated image, please...
Thanks...

Hi Andrie - I had wondered the same thing, and you can will see my exchange with Jaafar asking this question earlier in this thread. I tried adjusting the code to display a larger image, but as Jaafar points out, it starts to obscure the text at a certain point - from memory, that 'point' is at the 48 x 48 pixels size (or, in a pinch, maybe 64 pixels, but it would depend on the GIF).

I would echo Jaafar's suggestion - it would make more sense to use a Userform, as there isn't an obvious difference between 32px v 48px.
