Opening attachment stored in MS Access using C#

Question

I have a column in my table stored in MS Access as a Attachment data type. It stores various files such as docx, pdf's etc. I am trying to display a file from the table using a documentViewer (obtained from XtremeDocumentStudio .NET). I also have a combo box
on my form with a list of employee ID's. When a particular ID is selected from the combo box I want the associated attachment with that employee to be displayed in the documentViewer. So the SQL may look like the following:
SELECT EmployeeAttachment FROM Employee WHERE EmployeeID = 2;
I have been stuck on this problem for a while and am not sure on how to implement it. Any help or ideas on how I would display the attachment in the documentViewer would be greatly appreciated. Thank you.

Hello,
For getting the attachment filed part of your question, you could have a try with the Microsoft.Office.Interop.Access.Dao:

To save the read attachment to a temp document file and use that file as the data source.
For how to binding the documentviewer control with the data source, since this is a 3^rd control, it is beyond the scope of our support, I suggest that you could ask it on the XtremeDocumentStudio .NET forum:

Or, if your app is a WPF project, you could also consider using the Microsoft DocumentViewer control and here is an example for its usage:
