AdsExtendedReader and speed/locks

$

Hi,

 

I have written a replication program which uses the AdsExtendedReader (The reason I wrote my own is because of ADS problems using from ADT to DBF. Basically around deleted records).

 

I currently use an AdsExtendedReader which is very fast but I have a few users experiencing temporary freezing when using another program on the source database which is ADT.

 

I have a couple of questions :-

 

1) Does the AdsExtendedReader lock a record when executing the Read() or Seek() methods?

 

2) Would creating SQL statements to do the insert/update/delete operations be quicker on the DBF destination db (it does have a DD) than using the ExtendedReader due to caching etc...

 

 

Regards

 

Mike
