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.

MORE INFORMATION

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.
