View 2 RepliesHow To Save Binary File From SQL Server
Sep 11, 2010I'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.

Save Data To A Text File On A Remote Server?
Mar 13, 2011I'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)

The user can save rows and add rows to maintain a client list, but when I release an update, I have to install it without the database file. If I install with the database file, then their current client database is replaced with a new blank database.
my issue is that I need to add columns to tables in their existing database without overwriting their current rows. For example, i have columns for client name, address, and phone number currently. On my next update, I want the user to be able to save client birthdays. Here is what I have:

TextBox Save To Txt File Without Using The Save File Dialog
Mar 11, 2010I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
