SYMPTOMS
========

While debugging, no value is displayed if you add properties of objects or
fields of User Defined Types (UDTs) that are accessed by a WITH Statement to the
Watch Window. Instead, the message "Expression not defined in context" is
displayed.

NOTE: You cannot use the WITH statement itself from inside the Debug Window.

STATUS
======

This behavior is by design.

Steps to Reproduce Problem
--------------------------

1. Start a new project in Visual Basic. Form1 is created by default.

2. Choose Module from the Insert menu, to add a new module. Module1 is created
  by default.

3. Add the following code to Module1:

        Type test
           x As Integer
        End Type

4. Add the following code to the Form1_Click event procedure:

        Dim t As test
        Dim y As Integer

        With t
           y = .x
        End With

5. Highlight .x in the code window of Form1, and choose Add Watch from the Tools
  menu. Click the OK button of the Add Watch Dialog box.

6. Create a Breakpoint at the line y = .x, by pressing the F9 key when the
  pointer (cursor) is on that line.

7. Press the F5 key to Run the program. Click Form1. Execution stops at the
  breakpoint, but no value for x is displayed in the Debug Window.
