how can I change this code for it to automatically submit.
Code:
System.Web.HttpContext.Current.Response.Write("<html><body><form method=""post"" action=""[URL unfurl="true"]http://159.18.103.228/unpservice/UNPPaymentService""><input[/URL] type=""hidden"" name=""paymentRequest"" value=""")
System.Web.HttpContext.Current.Response.Write(Replace(xmlText, """", """))
System.Web.HttpContext.Current.Response.Write("""><input type=submit value=PayNow></form>After clicking </body></html>")
