[AccessD] Declare function question -- correction

Thanks.   I had tried that, but screwed it up in the Alias by renaming the function by mistake --   mapisendEmail  instead of mapisendmail

Your post got me straightened out, and I understand the syntax better.

The joy of Vista.


Thanks again,
Carolyn Johnson

  The problem is that Alias is what is in the .dll, not what you call it.

  So it should be Declare Function MAPISendMailOE lib... ALIAS
  MAPISendMail ....

  Sorry -- the original MAPISendEmail does not have the Alias included.
  I was playing around with getting it to work and added that.

    I have code to send an email via Outlook Express.   It uses the
  following function.

    Declare Function MAPISendMail _
        Lib "c:\program files\outlook express\msoe.dll" Alias _
        "MAPISendEmailOE" ( _
        ByVal Session As Long, _
        ByVal UIParam As Long, _
        message As MAPIMessage, _
        ByVal Flags As Long, _
        ByVal Reserved As Long) As Long


    Since Outlook Express is not part of Vista, I need to also have a
  similar function for Windows Mail with the corresponding dll:

    Declare Function MAPISendMail _
        Lib "c:\Windows\System\mapi32.dll" ( _
        ByVal Session As Long, _
        ByVal UIParam As Long, _
        message As MAPIMessage, _
        ByVal Flags As Long, _
        ByVal Reserved As Long) As Long


    I tried to rename the first one to MAPISendMailOE and then choose the
  function to call based on the operating system (determined when the
  database is first opened).   

    When I rename the function, I get the error  "Can't find DLL entry
  point MAPISendEmailOE in c:\program files\outlook express\msoe.dll" on
  the WinXP computer.   Same type of problem if I rename the Vista
  version.


    How do I have both functions available and call the appropriate one
  for the specific computer?


    Thanks
