All is well until your clientdataset decides it wants to update its
rows. When it tries, of course it can't, because the infopower query -
specifically, the transaction it is appropriated to -- has a lock on one of
the rows. The message should more accurately say "Record Changed by
another Transaction" but user/connection/transaction are all one and the
same with BDE data access programming.
To look for a solution, take your problem to the Midas newsgroup on the
Borland forum. This one is a FAQ, for sure. It's not a database problem
though, which is what this list is for.
