How To Save Binary File From SQL Server

Sep 11, 2010

I'm trying to save a binary file stored in a SQL database with a SaveDialog, the function RetrieveFile retrieves the specified file from the database as a Byte array, here's what I have so far:

Private Shared Function RetrieveFile(ByVal filename As String) As Byte()
Dim connection As New SqlConnection("Data Source=SERVERSQL2008;Initial Catalog=NorthPole;Integrated Security=True")
Dim command As New SqlCommand("SELECT pcfFile FROM Items WHERE pcfFileName=@Filename", connection)
command.Parameters.AddWithValue("@Filename", filename)
connection.Open()
[Code] .....

Files are saved as "SqlDbType.VarBinary" within the database.
I get: "Index was outside the bounds of the array." on:
Dim retrievedBytes As Long = reader.GetBytes(1, startIndex, buffer, 0, ChunkSize)
The MemoryStream appears to not be retrieving the data yet the SQL syntax is correct.

FileOpen(1, "E:FileWithData.dat", OpenMode.Binary)

I keep getting an incorrect function at FileOpen

I saw some methds which take numerous lines of code but I like to keep my code very simple so I can easily tell what it does.

Jan 20, 2011

I'm wounder if it's possible to save both string and images to the same binary file? I know that you can save them independently with one file for strings and one for images. But i would like to save both in to the same file.

If it's not possible with binary files, when what's my options?

Sql Server - Optional SQL Parameters For Binary File UPSERT

Sep 16, 2010

I'm using a stored procedure to updateinsert data into a table using MERGE. One of the items being inserted is a VarBinary file. Now if I wish to add a new file it's just a case of using ReadAllBytes as below, to remove the file I pass DBNull. Now what if other fields are being updated but the file is not being changed? I want the field to remain untouched unless I'm replacing the file or deleting it as above. I cannot add the file via the parameter again as it may only exist in the database, unless I read it first and write it back which seems pointless. [Code]

Save Data To A Text File On A Remote Server?

Mar 13, 2011

I'd like to save data to a text file on a remote server I have. There are no security issues here, just the method.

Dim FILE_NAME As String = "123.456.789.012/variables.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

[Code].....

I know it's not the most secure way of doing things, but the end data has to be in the txt format, otherwise I'd have used MySQL.

Save A SQL Server Image Data Type To The File System?

Jul 12, 2010

I'm having issues with the way I've been reading my image datatype blobs from my SQL database (code below). This code works fine when I access this page directly. The PDF will open and works just fine. However, when I try to use this page to download a file and save it to the file-system programmatically, it fails (500 server error) and I've verified that it's the same URL either way.So, my question is what is the best way to download a file from a database image datatype and save it to disk?PDF.aspx

Replace Content In PDF And Save Binary?

Aug 6, 2011

I need to add some information to a PDF (Trim Box proporties, actually replace Media Box proporties with Media Box and Trim Box proporties), and I dont have the support in my PDF-motor. So I found out that I can use Notepad++ to open the PDF as a text file and simply add the Trim Box properties as a string and save it. Now I want to do it automatically with vb.net. When I use Stream Reader/Writer the PDF gets destroyed and loses information (Stream Reader dont read all the NUL, SOH, STX etc. I guess). I tried to read the PDF using ReadAllBytes/WriteAllBytes and then it works good, but then I don't know how to replace "Media Box ..." with "Media Box.Trim Box.". I try to use IndexOf but I can only search for single Byte not the whole string. I'm not good in binary and thats perhaps the problem :-). Does anyone have a better way doing it or how do I search for my string "Media Box" in binary?
