Just now, I test three tires programming with MTS and Midas in nt4.
Use AdoDataSet in AppServer to access Ms SqlServer 7, and there's a table
include Blob field in client side.
When I change properity [poFetchBlobsOnDemand] to true in DataProvider, and
use fetchblob() in client side. It give me such prompt when running:
"Project XXX raised exception class EOleException with messgage
'unable to find a record. No key specified'. proces stoped.
Use Step or Run to continue."
If I change ADODataset to Ttable with ODBC as connect way, and hook
DataProvider to that table, it will works fine. Why?
\\Comment: the user that create table is different from the \\ user that
access the table.
\\  So I set ResolveToDataSet to true, and table name is dbo.TableName.
\\ if set them back to original value, it will work, but we have to use
these function.
