Actually, that *causes* a problem, since it leaves the handle locked. GuangHe
needs the full solution:
> ptr = MemHandleLock(recordH);
> offset = record.fields[note] - ptr;
> FldSetText (fld, recordH, offset, StrLen(record.fields[note])+1);
> MemHandleUnlock (recordH);
Note that the final MemHandleUnlock is *in addition* to the MemHandleUnlock
already at the end of the function he's looking at. Each call to MemHandleLock
needs to be matched with a call to MemHandleUnlock. The one that's already
there matches the one in AddrGetRecord. The one we're adding matches the call
to MemHandleLock we're adding.

Subject: Re: Question about MemDeref ?
Use

hope this solves your problem.
