Question

Hi, Recently the study vb.net but I still have not figured out how do I remove an image or an executable from the resource. If I put an image and add to the resource and I would extract C: \ foto.jpg how can I do? Thanks in advance, I apologize for my vb knowledge is that English

You could use the GetManifestResourceStream method to get the embedded image as a stream, read this stream in a buffer and write it to the disc using the WriteAllBytes method:

Using Stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("AssemblyName.image.jpg")
    Dim Buffer(Stream.Length) As Byte
    Stream.Read(Buffer, 0, Buffer.Length)
    File.WriteAllBytes("image.jpg", Buffer)
End Using

This should work for small files, but if you have some very big files embedded inside your assembly it would be better to read them in chunks to avoid consuming lots of memory:

Using stream As Stream = Assembly.GetExecutingAssembly.GetManifestResourceStream("AssemblyName.image.jpg")
    Using fileStream As FileStream = File.Create("image.jpg")
        Dim bytesRead As Integer
        Dim buf As Byte() = New Byte(1023) {}
        Do While (bytesRead = stream.Read(buf, 0, buf.Length) > 0)
            Dim actual As Byte() = New Byte(bytesRead - 1) {}
            Buffer.BlockCopy(buf, 0, actual, 0, actual.Length)
            fileStream.Write(actual, 0, actual.Length)
        Loop
    End Using
End Using
