I also tried to get this to work on a form.. I did notice the property defaults to BMP when a picture is selected and dropped on the form in a picture box or image box. the Gif would appear, but not animate.
A sprite control component is available, but looking it over you have to have the Gif89 broke up to it's individual file.
some how the vb6 sets the Gif as BMP. if there is a way to set the property of the picture to it's original form then the Animated Gif should animate.
The only way to try to get the Gif to Animate, might be to call it from a file to the Image box. there is a URL property within the setting of the image box that I was going to try this with..
