Unable To Delete Record In Database
Mar 5, 2009I am connected to a mdb using OleDb. The Connection code is :
' GET CONNECTED TO DB
Try' Open a connection to the database.cn = New OleDb.OleDbConnection(strConnection)cn.Open()
' Load Data Adapteradapter = New OleDb.OleDbDataAdapter(strSelect, strConnection)
' Create Auto generated Insert, Update, Delete cmds for Tableautogen = New OleDb.OleDbCommandBuilder(adapter)
[Code] .....
Add & Update are working perfectly, but delete doesn't update in the db. While application is running it shows that data is deleted, but when I run again, I see the same data, so its not physically deleting from the db. Add & Update both are working perfectly even after re-running.Can anyone tell me where am I going wrong in delete part. The row is also proeprly selected. No exceptions, yet why not deleting physically.

View 1 RepliesUnable To Log All Errors To A SQL Database?
Jan 26, 2010Okay, I've never used "THROW NEW EXCEPTION" before, and I'm having a hard time understanding it completely.
When a handled error occurs (in a try..catch block), what should I do?
I display a message to the user already in the catch block.
I want to be able to log all errors to a SQL database.
Previously, I would always write a method called LogError, pass the exception into the sub, and it would log it to a SQL database. I'm not sure if there's a built in function for this or not.This will tell the user that there is an error. If I put a call out to LogError(ex) above the dim d as new dlgexception line, then it could log it in the SQL server.
I just feel that I am not doing this the right way.And I am very confused about the THROW NEW EXCEPTION. Why would you ever ned to throw an exception? Wouldn't you just handle it? What is the point?And, why would you throw an error inside of a Catch statement? I seen this done in examples. If the error was already thrown (which sends it to the Catch block), why would you throw it a second time?
