Database Images

[SSgtBarry]

I want to create a database for parts. There are 6000 parts. I want to include an image for each part. Is it better to put the image file into a table (field) or to create a field with a link to the image in an external file folder? Thank you in advance!

link to external file otherwise your db will fill up fast.
use this code below to allow users to open the image.
OpenNativeApp txtBox
'where the text box has the path to the file.

Paste this code into a module, and it will open ANY file in its native application.
In a form put the field and a button to open it.




if the file is myFile.pdf, will open it in acrobat
if the file is myFile.doc, it will open the doc in Word
if its just a file path, it will open in file explorer.
etc..


usage:
OpenNativeApp txtBox


paste this code into a module

'Attribute VB_Name = "modNativeApp"
'Option Compare Database

Can also use Image control to dynamically display images in form or report. Specify file path/name in ControlSource. Review https://www.accessforums.net/showthread.php?t=73766
