The pathname or HTTP URL of the picture or animation file displayed on the button.

Notes

If you want to use AVI files, keep in mind that only simple AVI animations can be played. Specifically, the animations to be played by this control must meet the following requirements:

· There must be exactly one video stream and it must have at least one frame.

· There can be at most two streams in the file (typically the other stream, if present, is an audio stream, although the control ignores audio information).

· No palette changes are allowed in the video stream.

f using the abmGetPicture function from within Visual Basic 6, remember to convert the returned value from UNICODE using the StrConv function and its related vbFromUnicode option, as in the sample below:

MsgBox StrConv(abmGetPicture(Command1.hwnd), vbFromUnicode)
