The following piece of code can be used to write a memory stream to any browser. In my case its a pdf file so i am using “HttpContext.Current.Response.ContentType = “application/pdf” ” only this line is changed when there is amy other type of file in memory stream:

Public Sub ViewMS(ByVal fs As MemoryStream)
	Dim buffer(fs.Length) As Byte
	fs.Position = 0
	fs.Read(buffer, 0, fs.Length)
	HttpContext.Current.Response.Buffer = False
	HttpContext.Current.Response.ContentType = "application/pdf"  'In my case its a pdf
	HttpContext.Current.Response.OutputStream.Write(fs.GetBuffer(), 0, fs.Length)
	HttpContext.Current.Response.Flush()
	HttpContext.Current.Response.End()
	fs.Dispose()
	fs.Close()
End Sub

Hope this may help anyone
