How to use ADO stream method

[masoud_sedighy]

I would like by using ms access (FE) read pdf files from shared folder and then write this pdf file in varbinary (max) column of sql server table. And also reading this pdf file by accesing to this varbinary (max) column.
I found a almost similar question in the net that was using ADO stream method.

I would like to know can i use ADO stream method for saving and retrieving pdf files from sql server by using ms access (FE)?

Just attach the table in the FE.
Then open the PDF by calling this sub.
Paste this code into a module and it will open any file in its native app.
Feed it the pdf path and it will open in acrobat....
Usage: opennativeapp txtBox

There some code from this site that I used to copy an image file to a OLE field and back to a file. If the varbinary type shows up at an OLE object in Access it might get you started.

How does the varbinary field show up in a linked table to a sql server table?
