BUG: Debugger.SetNextStatement Displays Dialog Box

• Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0
• Microsoft Visual J++, versions 1.0, 1.1
• Microsoft Visual InterDev, version 1.0
• Microsoft Visual Studio 97

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 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.
