video materials database (urgent)

hi all ,

i make a database of video materials and pdf notes of some subject. it has a table called Materials , this table has the following fields:

1-material_ID (autonumber)

2-material_Name(text)

3-material_Video(attachment)

4-material_PDF(attachment)

and i have a form that has a combox of matrial_name list shows the name, material video and material pdf field . then i put a button and an activeX media player control , such that when i click this button it plays the video in this activeX wmplayer control.

i tried " material_video".fileURL but it returns nothing so the wmp doesn't play the vido.

how to solve this problem.... any other ideas are welcomed to play this video.

thanks in advance,
