I was wondering if there was a way to get the process ID on a record that locked using VB.

Allow me to explain more...

I am using ADO, server side cursors, and pessimistic locking to lock a row when a user accesses it. If another user tries to access the record, I can capture the error to see that it's locked. What I am looking for, is if there is a way to then see what process ID has the record lock to determine the user name who has the record locked.

Help? :-)
 
What dbms are you using? JET?
 
I'm using SQL Server 7.0 and ado is connecting via OLE DB driver for SQL Server.
 
Check the Connection Errors collection for the error number and if a NativeError is returned.

I would recommend not using the pessimistic locking, (or a server side cursor), but rather use a TimeStamp and when a user tries to update a record which has been changed since the last (re)query, comparing the TimeStamp to see if the data has changed since.
This can be done effectively using a stored proceedure.
 
A NativeError is returned. To check and see if a record is locked, I am checking for an error code 1222.

per requirements, I have to use locking thru sql server and pessimistic locking for this specific functionality. The majority of the application is written to use client side cursors with optimistic locking. Previously I had locking handled programmatically, but the technical project manager requires that sql server locks be used.
