Free Busy Provider crashes   

Hi All,



I am trying to implement the FreeBusy Provider for Outlook. Just to see if 
things work as expected i partially implemeted the interfacese. I.e. didnt 
fetched data from any valid source but just returned same data for every 
user.



Outlook does loads the DLL instanciates the IFreeBusySupport object calls 
LoadFreeBusyData in which i return it a IFreeBusyData interface. Later using 
this interface it calls IFreeBusyData::EnumBlocks from which i return an 
interface for IEnumFBBlock. At this point outlook calls EnumBlocks two times 
and i retrun it the same interface for both the calls.



Then Outlook calls IEnumFBBlock::Next from this I just populate the first 
FBBlock_1 and returns S_FALSE. And Outlook crashes just after the call 
returns. It crashes every time at the same address for every profile. the 
address is "0x3044747b" the call is from OUTLLIB.DLL, I know this is not of 
any help but still..



Here is the implementation for the Next function.



HRESULT EnumFBBlock::Next(LONG celt, FBBlock_1 *pblk, LONG *pcfetch)

{

    memset(pblk, 0, sizeof(FBBlock_1) * 32);

    pblk[0].m_fbstatus = fbOutOfOffice;

    SYSTEMTIME sysStTime = {0}, sysEdTime = {0};

    FILETIME fileStTime = {0}, fileEdTime = {0};

    //start time

    GetSystemTime(&sysStTime);

    sysStTime.wHour += 6;

    SystemTimeToFileTime(&sysStTime, &fileStTime);

    FileTimeToRTime(&fileStTime, &pblk[0].m_tmStart);

    //end time

    GetSystemTime(&sysEdTime);

    sysEdTime.wHour += 7;

    SystemTimeToFileTime(&sysEdTime, &fileEdTime);

    FileTimeToRTime(&fileEdTime, &pblk[0].m_tmEnd);

    *pcfetch = 1;

    return S_FALSE;

}

Any idea what might be going wrong here.
