You can use the Visual Studio Immediate window to execute a function or subroutine while your application is not running. If the function or subroutine contains a breakpoint, Visual Studio will break execution at the appropriate point. You can then use the debugger windows to examine your program state. This feature is called debugging at design time.

The following procedure shows how you can use this feature.

To hit breakpoints from the Immediate window

1. Paste the following code into a Visual Basic console application:

   Module Module1
   
       Sub Main()
           MySub()
       End Sub
   
       Function MyFunction() As Decimal
           Static i As Integer
           i = i + 1
           Dim s As String
   
           s = "Add Breakpoint here"
           Return 4
       End Function
   
       Sub MySub()
           MyFunction()
       End Sub
   End Module
   

2. Definir um ponto de interrupção na linha que lê, s="Add BreakPoint Here".

3. Digite o seguinte na imediata janela: ?MyFunction <enter>

4. Verify that the breakpoint was hit, and that the call stack is accurate.

5. On the Debug menu, click Continue, and verify that you are still in design mode.

6. Digite o seguinte na imediata janela: ?MyFunction <enter>

7. Digite o seguinte na imediata janela: ?MySub <enter>

8. Verifique se o ponto de interrupção e examine o valor da variável estática i na Locals janela. It should have the value of 3.

9. Verify that the call stack is accurate.

10. On the Debug menu, click Continue, and verify that you are still in design mode.
