Hello,

I have added a reference to the asmx file given by the our 3rd party vendor. On buttonclick I am trying to login to the tool with the code below

Whenever I try to run the app and provide the username,pwd and hit on the login buttn I am getting this error

System.NullReferenceException: Object reference not set to an instance of an object.

at this Line "UsernameToken userTok = new UsernameToken(userName, pwd, Microsoft.Web.Services3.Security.Tokens.PasswordOption.SendPlainText);"

When I build the solution it says build succeeded.

Please help
