MAPI issue different to Outlook Express than Outlook

[ktechit]

Have to resolve or come up with a work-around for some of our users. Our application has a button "Send Email" that works fine if the user's default mail client is Outlook Express, Eudora, or other simple email clients. It simply opens a new email window, like normal.

If Outlook 2000 -- 2003 is the default mail client, we get this error :
"OLE IDispatch exception code 0 from MAPImessages: Unspecified Failure has occurred. "

Our code for the "Send Email" feature is below:
************************
#DEFINE ERR_NOMAPI_LOC "It does not appear that you have MAPI installed. Mail could not be run."

thisform.logsession = .T.

IF !FILE(GETENV("WINDIR")+"\SYSTEM32\MAPI32.DLL");
AND !FILE(GETENV("WINDIR")+"\SYSTEM\MAPI32.DLL")
MESSAGEBOX(ERR_NOMAPI_LOC)
thisform.logsession = .f.
RETURN .F.
ENDIF

thisform.OLEMSess.signon
***********************************

now, we see that Outlook 2003 on one of our test computers pulls up mapi32.dll from:

C:\Program Files\Common Files\System\MSMAPI\1033\mapi32.dll

? So, is the only option to re-code for that location, or is there a statement that will be more general, to look in \system32 or \1033 for the correct mapi32.dll for the default mail client ?

didn't want to re-code and send out to all users, but will if necessary.

thanks for any help,

I'm not sure I understand why you need to know the exact path to the mapi32.dll. Can't you just check if you can create a mapi object? Something like...

IF TYPE([CREATEOBJECT("MSMAPI32.MAPISession")]) = "O"
  ? "MAPI Installed... proceed to email"
ELSE
  ? "MAPI Not Installed... proceed to inform user"
ENDIF

thanks for the suggestion. I've sent it on to the programmer for this software, will find out what he thinks on making a change like this, then rolling out to the clients. May have to wait until next version rollout for it if he has to make other changes also.

thanks again,
