Hello everybody, I'm having problems on reading some resources (images file .jpg) in my generated application from the CodeDOM.
I really don't understand how all it work , I hope you can give me help.

I'm trying to compilate a Test.Vb File with my source VB.NET code inside using Codedom ;
I use this code in one btncompile Button to compilate and add a 'xp.jpg' image to my generated assembly :

Dim Success As Boolean
        Success = CompileExecutable(Application.StartupPath & "\Test.Vb")
        Dim byteStream As New FileStream(Application.StartupPath & "\xp.JPEG", FileMode.Open)
        Dim bytes(CInt(byteStream.Length - 1)) As Byte
        byteStream.Read(bytes, 0, CInt(byteStream.Length))

        Using rw As New ResourceWriter(".\xp.resources")
            rw.AddResource("\xp", byteStream)
            rw.Generate()
            rw.Close()
        End Using
        MessageBox.Show("Test.vb " & Success.ToString & ControlChars.NewLine)

And this is the CompileExecutable function :

Dim sourceFile As System.IO.FileInfo = New System.IO.FileInfo(sourceName)
        Dim provider As System.CodeDom.Compiler.CodeDomProvider = Nothing
        Dim compileOk As Boolean = False
 
        If sourceFile.Extension.ToUpper(Globalization.CultureInfo.InvariantCulture) = ".CS" Then
            provider = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp")
        ElseIf sourceFile.Extension.ToUpper(Globalization.CultureInfo.InvariantCulture) = ".VB" Then
            provider = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("VisualBasic")
        Else
            Console.WriteLine("Source file must have a .cs or .vb extension")
        End If

        If Not provider Is Nothing Then
 
            Dim exeName As String = String.Format("{0}{1}.exe", sourceFile.Directory, sourceFile.Name.Replace(".", "_"))

            Dim cp As System.CodeDom.Compiler.CompilerParameters = New System.CodeDom.Compiler.CompilerParameters()
 
            Dim references() As String = {"System.Windows.Forms.dll", "Microsoft.VisualBasic.dll", "System.dll", "System.Drawing.dll"}
            cp.ReferencedAssemblies.AddRange(references)
            cp.CompilerOptions = "/target:winexe /m:Form1"

            cp.GenerateExecutable = True
            cp.OutputAssembly = exeName  
            cp.GenerateInMemory = False
            cp.TreatWarningsAsErrors = False
            cp.EmbeddedResources.Add(Application.StartupPath & "\xp.resources")
            Dim cr As System.CodeDom.Compiler.CompilerResults = provider.CompileAssemblyFromFile(cp, sourceName)

I used EmbeddedResources.Add and seems it works because now my generated file is more big and so it contains my resource 'xp.resources' file inside.

Now, how can I read my 'xp.resources' into the generated assembly ?
I'm receiving a 'null value return' when I try to load my image with this code :

Dim _imageStream As Stream
   Dim _assembly As [Assembly]

   _assembly = [Assembly].GetExecutingAssembly()
   _imageStream =  _assembly.GetManifestResourceStream("My.Resources.xp.JPEG")

Dim xp As System.Drawing.Image
xp = System.Drawing.Image.FromStream(_imageStream)
      Me.BackgroundImage = xp

Why the value returns null ? How can I avoid this or there is another way to read this embedded resource?
