TITLE   :PRB: Set of DEFAULT Changed After MAPI.SESSION Logon

KEYWORDS:kbCtrl kbMAPI kbvfp500 kbvfp500a kbvfp600 kbGrpDSFox kbDSupport kbCodeSnippet

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

 - Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Programmers often maintain a default directory in Microsoft Visual FoxPro
applications. They use this directory for the creation of temporary tables, work
files, and so forth. However, if a Microsoft Visual FoxPro application also
makes use of MAPI functions to send or receive mail, the default directory may
change without warning.

RESOLUTION
==========

In order to maintain the default directory and still use MAPI functionality,
store the current directory to a variable and switch back to it after you are
finished with the MAPI process with the following code:

   LOCAL loMAPISession, lcCurDir
   lcCurDir = SYS(5) + SYS(2003)
   *!* Create a MAPI Session object, logon then logoff
   loMAPISession = CREATEOBJECT("MAPI.Session")
   loMAPISession.Logon()
   *!* Perform mail functions here.
   loMAPISession.LogOff()
   CD (lcCurDir)
   RELEASE loMAPISession, lcCurDir

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

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

To demonstrate this behavior, save the following code to a new program file on a
computer with Microsoft Visual FoxPro version 5.0 or higher and Microsoft
Outlook.

When it is run, the program will first Change Directory (using the CD command) to
the directory in which the program file is located. It then prints the current
directory to the screen. The program creates a MAPI.SESSION object, logs in, and
then logs out. Finally, the current directory is printed once more: notice that
it has changed.

NOTE: This problem also occurs when you choose SEND from the File menu on the
main Microsoft Visual FoxPro menu. To demonstrate this, comment the first line
in the following code and run it. Close the Compose Mail screen when it appears,
and note that the current directory has changed.

   #DEFINE InCode

   CD JUSTPATH(SYS(16))
   CLEA
   ? "Current Directory Before Message: "
   CD

   #IFDEF InCode
   	LOCAL loMAPISession
   	*!* Create a MAPI Session object, logon then logoff
   	loMAPISession = CREATEOBJECT("MAPI.Session")
   	loMAPISession.Logon()
   	loMAPISession.LogOff()
   	RELEASE loMAPISession
   	? ""
   	? "Current Directory After MAPI Logon: "
   	CD

   #ELSE
   	*!* Call the compose mail window via File>Send
   	KEYBOARD '{ALT+F}'
   	KEYBOARD '{D}'
   	DOEVENTS
   	? ""
   	? "Current Directory After MAPI Logon: "
   	CD

   #ENDIF
