How do I open a file which is saves into the database as byte()

So far, I got this and it's working

Dim myDoc as Byte()
myDoc = CType(dbDataRow("Document"), Byte())

From there how do I open this so the user can review this file.

Thank for the help.
 
' Convert the byte array to a string

Dim ascii As ASCIIEncoding = new ASCIIEncoding();

Dim strText As String = ascii.GetString(myDoc);
 
Do you know the type of data in your byte array or the original file name ?

if so you could just write your byte array out to a temp file and then use
Process.Start(tempfilename) so long as it has the correct extension and it
is mapped in windows.

Click to expand...

You will have to save it to disk using 'System.IO.FileStream' and then
use 'System.Diagnostics.Process.Start' to open the file.
 
So I should Save the Type of the file within the database right.
and then how do you go to create the file (byte array out to a temp file)
because i don't know if it is a text or graphic or media file

Thank again
