  • userName
    String. User name to authenticate. Default is an empty string: "".

  • password
    String. Password to authenticate. Default is an empty string: "".

  • showUI
    Boolean. Whether to display progress of the operation. Default is False.

  • connectionTimeout
    Int32. Timeout interval in milliseconds. Default is 100 seconds.

  • onUserCancel
    UICancelOption. Action to be taken when the user clicks Cancel. Default is ThrowException.

Exceptions

The following conditions may cause an exception:

Remarks

If showUI is set to True, a dialog box shows the progress of the operation and includes a Cancel button that the user can click to cancel the operation. Because the dialog box is not modal, it does not block user input to other windows in the program.

If the server does not respond within the interval specified in connectionTimeout, the operation is cancelled and an exception is thrown.
