I have a insert stored procedure "AGProfileSetup"
Parameters -----
   @UserId uniqueidentifier,
    @ProfilePic image,
    @ProfilePicMIME varchar(50)

used to insert an image for a user into a database.  The problem is from my understanding sql type "Image" is some kind of binary format :D  I don't know how to pass a binary through the InsertParameters.Add function.   Whats the best way to do this?  By the way I am using ASP.NET 3.5 and MS SQL 2008
Dim imageBytes(Picture.PostedFile.InputStream.Length) As Byte
        Picture.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length)
 
        Dim AGDataSource As New SqlDataSource()
 
 
        AGDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("AGConnectionString").ToString()
 
        AGDataSource.InsertCommandType = SqlDataSourceCommandType.StoredProcedure
        AGDataSource.InsertCommand = "AGProfileSetup"
 
        AGDataSource.InsertParameters.Add("UserId", CurrentUser)
        AGDataSource.InsertParameters.Add("@ProfilePic", TypeCode.Byte, imageBytes.ToString())
        AGDataSource.InsertParameters.Add("@ProfilePicMIME", MIMEType)
 
AGDataSource.Insert()
AGDataSource = Nothing

You need to pass a byte array from the image that you are working with, not a string, so remove the .ToString() from imageBytes.ToString().

Im sorry, I should have said that.   But, I put ToString() because imageBytes was throwing an error.  I will post that error to, I tried that on another attempt.

ERROR: Error      1      Overload resolution failed because no accessible 'Add' can be called with these arguments:
    'Public Function Add(name As String, dbType As System.Data.DbType, value As String) As Integer': Value of type '1-dimensional array of Byte' cannot be converted to 'String'.
    'Public Function Add(name As String, type As System.TypeCode, value As String) As Integer': Value of type '1-dimensional array of Byte' cannot be converted to 'String'.      C:\Documents and Settings\Administrator.ACFUNDING.000\My Documents\AG\AG Website\Settings\Profile\Profile.aspx.vb      58      9      C:\...\AG Website\

Thats why I added the .ToString()

Is there an easier way to do this?

AGDataSource.InsertParameters.AddWithValue("@ProfilePic", imageBytes)

all I want to do is upload a picture from asp.net 3.5 to my sql 2008 db table hehehe

I have never inserted objects into a database before from asp.net, I didn't it would be this tricky, because its so easy to insert everything else ;D

Aah, yes, I missed that you are using an SqlDataSource.  

Try this instead:

Storing Binary Files Directly in the Database Using ASP.NET 2.0
http://aspnet.4guysfromrolla.com/demos/printPage.aspx?path=/articles/120606-1.aspx

Using myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("ImageGalleryConnectionString").ConnectionString)
 
    Const SQL As String = "INSERT INTO [Pictures] ([Title], [MIMEType], [ImageData]) VALUES (@Title, @MIMEType, @ImageData)"
    Using myCommand As New SqlCommand(SQL, myConnection)
      myCommand.Parameters.AddWithValue("@Title", PictureTitle.Text.Trim())
      myCommand.Parameters.AddWithValue("@MIMEType", MIMEType)
 
      'Load FileUpload's InputStream into Byte array
      Dim imageBytes(UploadedFile.PostedFile.InputStream.Length) As Byte
      UploadedFile.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length)
      myCommand.Parameters.AddWithValue("@ImageData", imageBytes)
 
      myConnection.Open()
      myCommand.ExecuteNonQuery()
    End Using
  End Using
End Sub

So I am guessing this is an example of when you should not use a stored procedure : )

I'll give it a try : )!

I try to use stored procedures as much as possible, so if that is what you would like to do, it is a simple fix:


Using myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("ImageGalleryConnectionString").ConnectionString)
 
    Using myCommand As New SqlCommand("InsertImageData", myConnection)
      myCommand.CommandType = CommandType.StoredProcedure
      myCommand.Parameters.AddWithValue("@Title", PictureTitle.Text.Trim())
      myCommand.Parameters.AddWithValue("@MIMEType", MIMEType)
 
      'Load FileUpload's InputStream into Byte array
      Dim imageBytes(UploadedFile.PostedFile.InputStream.Length) As Byte
      UploadedFile.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length)
      myCommand.Parameters.AddWithValue("@ImageData", imageBytes)
 
      myConnection.Open()
      myCommand.ExecuteNonQuery()
    End Using
  End Using
End Sub
