    Unhappy MAPIReadNext works well but MAPIReadMail doesn´t work.

    Hi everybody,

    As i said, MAPIReadNext function return 0 and a pointer to unread message on windows live mail, but after it, if i send a MAPIReadMail command i receive a 0 return code again, but the pointer to struct message is NULL.

    Portion of my code:

    MapiMessage* message ; // Created but not initialized
    ULONG err=0; // Created and initialized
    LPSTR rgchMsgID; // Created but not initialized

    // return 0 and put 546 into rgchMsgID
    ULONG uFindRet = lpfnMAPIFindNext(lhSession,0L,"","",MAPI_LONG_MSGID|MAPI_UNREAD_ONLY,0L,rgchMsgID);

    err = lpfnMAPIReadMail(lhSession,0L,rgchMsgID,MAPI_BODY_AS_FILE,0,&message); // Return 0

    if (message==NULL) // true, because message is NULL.
    err = FAILMAIL; // Badly, Allways execute this line.

    Can someone help me ?

    I try everything i knew.

    since now, thanks.

    Well....of the top of my head...the third parameter is supposed to be the message id which is allocated by the caller. In your case...you actually pass in some random value.
