RE: DmWrite behavior.

[Bryan Nystrom]

I can't post the entire class, but here is the offending class function:

typedef struct {
        long    mModifiedFields;
        long    mUniqueId;
        long    mDateA;
        long    mDateB;
        long    mDateC;
        long    mDateD;
        long    mPosition;
        Byte    mItemA;
        Byte    mItemB;
        Byte    mItemC;
        Byte    mItemD;
        long    mRepeatDate;
        UShort  mRepeatInterval;
        char    mName;
 } RecType;

Err CXYZItem::ChangeRecordItemA(void)
{
        Err                     err;
        VoidHand                recordH;
        XYZRecTypePtr   src;
        XYZRecTypePtr   nilP = 0;
        
        // Get and Lock the record which we are going to change
        recordH = DmQueryRecord(m_DmOpenRef, m_Index);
        src = static_cast<XYZRecType *>(::MemHandleLock (recordH));

        err = ::DmWrite (src, (ULong)&nilP->mItemA, &mItemA, sizeof(src->mItemA));
        MemPtrUnlock (src);     

        return err;
}

And the code you were using to write these members?
(You posted pseudo-code before...)
