View 10 RepliesI Fill a DataTable using a SQLDataAdapter then use a BindingSource as my DataGridViews DataSource. My DataGridView contains a ComboBoxColumn named "Status". There are two ways to update the Status column. One, the user can change the value by clicking a cell in the column then the combobox appears and they make their selection. Second, the user can click a button on the form and the Status for all the visible rows are changed to "Exported". I use a stored procedure as my adapters Update command.

I get this error at the Commit of a transaction in a desktop application:
This OleDbTransaction has completed; it is no longer usable.
Other posts I have seen with similar error suggests this can occur if it takes a long time, or contains large amounts of data. This is not the case here.Logging tells me it takes 140 ms from Begin to Commit and about 10 commands executed inside the transaction.It is using an Oracle database.This class is a simplified version of my database class:
Class MyDatabase
Private mConnection AS OleDbConnection
Private mTransaction AS OleDbTransaction

Is it not allowed to run a select inside a transaction like this? Or can it be done by running the transaction in a specific isolation level (I see that the BeginTransaction method has an optional parameter for doing this) ? ..Or some other sollution..? In my case, it was not a problem to move the select to run before the transaction started, but what if you need to run selects that must run inside the transaction?
I've seen plenty of examples of transactions in the actual store procedure's SQL. But I'm wanting to do the transaction and keep track of it in code. I tried this but it says that my insertcommand's transaction object is null. How can I fix this?

Error : Execute requires the command to have a transaction object when the connection assigned to the command is in a pending local transaction. The transaction property of the command has not been initialized..

View 1 RepliesI have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?
