-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Issuing a CLOSE ALL command in the BeforeBuild event of the Project Hook object
causes the following error:

  Mismatched pushjmp/popjmp call

After the error appears, clicking OK in the dialog box causes Visual FoxPro 6.0
to terminate with a C0000005 error or an application error message under Windows
NT.

STATUS
======

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

This bug was corrected in Visual Studio 6.0 Service Pack 3. For more information
about Visual Studio service packs, please see the following articles in the
Microsoft Knowledge Base:

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

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

1. Create a PRG.

2. Cut and paste the code below into the PRG:

  oProject=CREATEOBJECT("myprojecthook")

  STRTOFILE("wait window","main.prg")
  MODIFY PROJECT test NOWAIT

  _VFP.ActiveProject.Files.Add("main.prg")
  _VFP.ActiveProject.ProjectHook=oProject
  _VFP.ActiveProject.Build

  DEFINE CLASS myprojecthook As projecthook

     PROCEDURE BeforeBuild
     LPARAMETERS cOutputName, nBuildAction, lRebuildAll, lShowErrors, lBuildNewGuids
        CLOSE ALL
     ENDPROC

  ENDDEFINE
   

3. Save and run the PRG.

  Note that Visual FoxPro produces a dialog box containing the "Mismatched
  pushjmp/popjmp call" error. When you click OK, Visual FoxPro terminates with
  C0000005 error or an application error message under Windows NT.
