Hi,
it is not advised to embed files within access. It can cause bloat and
problems with the 2GB file size limit.
Instead either hardcode or store the full path to the external file as a
string value. Access includes a windows media player active x control which
you can use to play the file...at runtime you could assign its url e.g.:
Me.YourPlayerControlName.Url = "c:\path to your file\yourfile.wmv"
HTH
Good luck
