SYMPTOMS
========

When you are automating the MSDEV.exe Debugger object, the SetNextStatement
method displays the following message:

  This operation will move the current location to a different function.

CAUSE
=====

The target line number of the SetNextStatement method is outside the scope of
the current function. The message is not suppressed during automation.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

MORE INFORMATION
================

The error message alerts the operator that this action, while permitted, might
cause unexpected behavior. It appears normally when you click Set Next Statement
from the debugger's shortcut menu to move the code execution location to another
function. However, during automation, this sort of informational message box
should never appear.

Steps to Reproduce Behavior
---------------------------

1. Create a default MFC .exe application. Name it SetNext.

2. From the ClassView window, expand the CSetNextDoc class. Double-click
  CSetNextDoc().

3. Click on the curly brace at the beginning of the function (at or near line
  31). Press the F9 key once to set a breakpoint there. The code should look
  something like the following:

  ...
  30: CSetNextDoc::CSetNextDoc()
  31:>{
  32:    // TODO: add one-time construction code here
  33: }
  34:
  35: CSetNextDoc::~CSetNextDoc()
  36: {
  37: }
  ...

  The line numbers are added for illustration only. The > represents a line
  with a set breakpoint.

4. Create a Visual Basic Script macro named SetNext. To do this, go to the Tools
  menu, click Macro, type "SetNext" (without the quotation marks) in the Macro
  Name field, and click Edit. Click OK on the Add Macro dialog box. Replace the
  SetNext subroutine with the following text and press Ctrl+S to save the macro
  file:

  Sub SetNext()
     Debugger.RunToCursor
     Debugger.SetNextStatement 36, "SetNextDoc.cpp"
  End Sub

  In this example, 36 represents a valid line in another function of the same
  source file of the SetNext application.

5. On the File menu, click Close. This closes the Macro window.

6. Execute the SetNext VBScript macro. To do this, go to the Tools menu, click
  Macro, click OK on any informational dialog boxes, and double-click SetNext
  in the Macro Name list.

RESULT: The message described in the SYMPTOMS section appears. Click OK to
dismiss it. On the Debug menu, click Stop Debugging.
