I am trying to accomplish the following:
1. From within a form that is used to create or edit an instance of a
class, allow a user to select a .pdf file from the client file system
(using a fileUpload control). On saving the form, I would like to copy
the .pdf file to the server file system to the directory C:\Ensemble
\CSP\app\pdf, and name the file: map_OID.pdf, where OID is the OID of
the object being created and/or edited.
2. From a table pane on a different page, have a link in each row that
would launch that object's saved .pdf in a separate browser window.
I already have the dataController working in the first page, and the
table pane working in the second page.
Any help would be appreciated. Thanks.

Or is it better to use the binary stream? Any input would be most
appreciated. Thanks.
appreciated. Thanks.

You need to have a class with a property of %GlobalBinaryStream
I know binary stream is the right class but after workign with WRC we figured GlobalBinarystream actually works
About displaying on the page
I know it would be ideal to have it load from the object's stream and display but till now I haven't figured out how to do that. There are some examples but it doesn't work for me and also I haven't put my heart and soul into making it work
So for now I store a copy in the object and one on the hard disk
1. to display you can have a link to the pdf on the server and browsers will open a new window/tab with the pdf in it
2. or you can load the pdf right in the page where you have your form. i have kept the right side empty and on click the pages display there
But the flip side to it is that this doesn't work on IE but thats ok for us as we are pushing people to use Chrome.
For IE we still have the link which opens the pdf in a separate window
If you want I can send you the sample code . It is pretty complicated.
Thank You,

Hi Mitch,
Here is some rough code,

Mitch,
Instead of loading the files in Cache database you can leave them
outside
of Cache and manipulate them with their names(paths) instead of OIDs.
Here are two examples which demonstrate this and are more closer
to what you want.They are made for images but the same way you can
use them for any files:

Instead of loading the files in Cache database you can leave them
outside
of Cache and manipulate them with their names(paths) instead of OIDs.
Here are two examples which demonstrate this and are more closer
to what you want.They are made for images but the same way you can
use them for any files:

Class VICS.EmployeeDemo Extends (%Persistent, %ZEN.DataModel.Adaptor)
