Asynchronous ADO and DCOM
Posted on 1998-11-17
Firstly, I am trying to get 5 (or more) threads in one process to connect (and eventually execute) asynchronously to an SQL Server (7 Beta 3) under VB5. The first one connects, but the others all sit aroiund and take up CPU. If I only have one thread in the process, it connects just fine and does not eat up CPU. How can I get many asynchronous threads working in the same process?
Secondly, when this single thread connects, I perform the async execute, and I want to return the data to another process (via DCOM). When ExecuteComplete is called, I use a
callback to comminucate with the other process, but it waits until the whole recordset is available i.e. all 5000 records are returned to executing thread. How can I return to the client process the recordset before it is complete?
