We use midas&MTS designer three tirs project, set Dataprovider's properity
ResolveToDataset true
Database is Sql Server 7.0

When test it with different Word97 files. Save to database or fetch it out
and show with OleContainer, it works fine with files whose filesize less
than 1M. But sometimes there's will be such error message when used with
some large Doc (right after Applyupdate or refresh after ApplyUpdate):
Project client1.exe raised exception class EOleException with message
'Invalid BLOB handle in record buffer'.

I add virtual RAM setting in appserver, the chance to it became less.
I also try to change it from ODBC to ADO for odbc, or use original ado
driver with it, the problem seems better.
I has no problem with ADO origianl driver yet. But I wonder when and why.
Has anyone had such problem before ?
