!!!!Sample Code:

const int MAX_USER_NAME = 100;
  const int MAX_PASSWORD = 100;
  const int MAX_DOMAIN  = 100;
 
  public static CredUIReturnCodes PromptForCredentials(
			ref CREDUI_INFO creditUI,
			string targetName, 
			int netError, 
			ref string userName, 
			ref string password, 
			ref bool save, 
			CREDUI_FLAGS flags)
  {
 
  StringBuilder user = new StringBuilder(MAX_USER_NAME);
  StringBuilder pwd = new StringBuilder(MAX_PASSWORD);
  creditUI.cbSize = Marshal.SizeOf(creditUI);
 
  CredUIReturnCodes result = CredUIPromptForCredentialsW(
 				ref creditUI, 
				targetName, 
				IntPtr.Zero, 
				netError, 
				user, 
				MAX_USER_NAME, 
				pwd, 
				MAX_PASSWORD, 
				ref save, 
				flags);
 
  userName = user.ToString();
  password = pwd.ToString();
				   
  return result;
  }
 
 
  string host = "Database Client";
  CREDUI_INFO info = new CREDUI_INFO();
  info.pszCaptionText = host;  
  info.pszMessageText = "Please Enter Your Enterprise ID";
 
  CREDUI_FLAGS flags = CREDUI_FLAGS.GENERIC_CREDENTIALS |
		CREDUI_FLAGS.SHOW_SAVE_CHECK_BOX |
		CREDUI_FLAGS.ALWAYS_SHOW_UI |
		CREDUI_FLAGS.EXPECT_CONFIRMATION;
 
  bool savePwd = false;
  CredUIReturnCodes result = PromptForCredentials(ref info, host, 0, ref username,
