It's me your junior programmer extraodinaire
I'm trying to display an image from my database but when I try to extract the file it only contains 6 bytes of data which causes my program to throw an error. My instructor informed me that the file is too small for an image, leading me to believe that I'm not storing it properly. I would be most gracious if someone could identify any code that might cause this to happen.
this is my function grabbing/storing the file
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
Dim _image As Byte()
_image = FileUpload1.FileBytes
Dim conn As New SqlConnection
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
cmd.Connection = conn
cmd.CommandText = "Insert INTO mrg_Image(Image, UserId) VALUES('@image', @id)"
cmd.Parameters.AddWithValue("@image", FileUpload1.FileBytes)
cmd.Parameters.AddWithValue("@id", 4)
conn.Open()
dr = cmd.ExecuteReader
conn.Close()
'FileUpload1.SaveAs()
End Sub
conn.Open()
file_bytes is the variable that contains 6 bytes as oppose to a thousand+ which an image should have
Dim file_bytes As Byte() = cmd.ExecuteScalar()
Dim file_bytes_memory_stream As New System.IO.MemoryStream(file_bytes)
Dim file_bytes_stream As System.IO.Stream = DirectCast(file_bytes_memory_stream, System.IO.Stream)
Dim the_image As New System.Drawing.Bitmap(file_bytes_stream)
context.Response.ContentType = "image/jpg"
the_image.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg)
conn.Close()
End Sub
