[SNArruda]

Hi everybody,

I builted an aplication that read emails from windows Mail. The MAPILogon returns 0, but when a try to send a MAPIFindNext before to use MAPIReadMail the return code is 16. There are emails unreaded in windows mail and i thing that the return code must be 0 for MAPIFindNext.

The windows mail is the default email manager.

I created an email account as "softools" and conected it to samuel.softools@ig.com.br

The MAPI in WIN.INI is 1 and set to MAPI32.DLL. I Loaded the MAPI31.DLL correctly with loadlibrary().

I thing is everything is fine but nothing is heppening

Some can help me ?

Sorry by poor english !

What do these return value 0 and 16 mean?
According to my "old" MSDN:

Return Values

MAPI_E_FAILURE

One or more unspecified errors occurred while matching the message type. The call failed before message type matching could take place.

MAPI_E_INSUFFICIENT_MEMORY

There was insufficient memory to proceed. No message was found.

MAPI_E_INVALID_MESSAGE

An invalid message identifier was passed in the lpszSeedMessageID parameter. No message was found.

MAPI_E_INVALID_SESSION

An invalid session handle was passed in the lhSession parameter. No message was found.

MAPI_E_NO_MESSAGES

A matching message could not be found.

SUCCESS_SUCCESS

The call succeeded and the message identifier was returned.

0 = SUCCESS_SUCCESS

16 = MAPI_E_NO_MESSAGES

I´m allways receive a return code 16, but the return code is not correct. There are messages unreaded in windows mail inbox, so, will must be 0.

I don´t know i cant read the unreaded emails in windows mail.

Two days ago i need to reinstall the windows vista to factory configuration. The partitions was recreated and the windows vista reinstalled. after this i installed the office 2003.

The Program was functioning correctly but now it stopped to function.

The email was readed normaly
