when i add a web service to my application , the auto code omits the "authentica tion header" i use . so its not generated in reference.cs . the authentication related stuff does not exist in it at all. whats the reason ?

i have a textbox and a status bar and a webbrowser on a tabpage. it is a chat screen for a messaging application. i want it to be like webbrowser on top , then textbox where i type , and then the status bar. but the webbrowser is filling the entire area always . the text box and the status bar are just where i want them to be.but then the bottom rows of the web browser are hidden behing these two controls. what can i do ?
