VS 2008 - Transaction SProc's In Code - Says That My Insertcommand's Transaction Object Is Null
Apr 29, 2009I'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?

Transaction Error On Call To Commit() When Select Has Been Executed Inside Transaction?
May 9, 2011I 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?
Transaction Object - The Transaction Property Of The Command Has Not Been Initialized
Mar 5, 2009What is this kind of exception?
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..
This one causes the error: Dim oOperation As COperationOutputTypeBS
oOperation = COperationOutputTypeBS.GetOperationOutputType(txtOperationCode.Text)

View 14 RepliesInsert SQL 2008 Parent And Child Rows In A Single Transaction?
Nov 13, 2010First, a little background (greatly simplified): I have two classes, one called Entity and one called Item which a subclass of Entity. They each store their individual properties in seperate SQL 2008 tables using TableAdapters generated by a strongly typed DataSet. The Entity class has a Save() method that looks like this:
Public Sub Save()
entityTableAdapter.Update(entityRow)
End Sub
[Code]....
Indeed, the SQL table does not contain a row in the Entity table with the necessary ID at this point because the transaction is not complete.
My goal is to prevent the Entity record from being inserted if inserting the Item record fails. I could write code to delete the Entity record again, but this does not seem very elegant to me...

View 8 RepliesUsing Keydown Commands In 2008?
Apr 8, 2009I am extremely new to visual basic and it is the first time i have ever tried to program anything. I am currently using Visual Basic 2008 Express Edition which I downloaded for free off of the mictosoft website. Anyhow, to the question at hand: I was wondering how one would use keydown commands in VB express 2008. I have looked far and wide and have yet to find an answer to this. To simplify it to a specifit answer how would I move (or rather, slide), say, a picturebox to the left of the screen by holding down the left arrow key and have the picturebox stop moving after I released the arrow key. By simply seeing how the code is I should be able to do it for any other keydowns.

VS 2008 - SQL Data Adapter Commands Parameters
Feb 22, 2010I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...
View 3 RepliesVS 2008 : Adding A One Second Delay Between Execution Of Commands?
Feb 20, 2010I have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?
VS 2008 Form_Load Terminates Despite Commands Left?
Jan 25, 2011i have a problem: I have a Form_Load-Method which is not doing all the commands in it. It just interrupts and jumps to the "Form_Paint"-Event, eventhough i did not yet paint anything or invalidated any object. The Form_Load-Method is this:
[Code]...
the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards. Can you help me? Because i really dont get it.

View 1 Replies.net - View Pending Changes On An SQL Transaction?
Mar 7, 2012While working on some functions that update my database, I was writing some quick tests just to make sure my functions were executing properly. When it comes time to actually update the database I can pass a transaction to a function and then commit it:
user.Assignment("assignment value for some column in table", connection, transaction)
transaction.Commit()
I am curious if there is a way to write a quick test that can verify that the transaction will actually update certain rows before committing?
(pseudoish-code)
user.Assignment("assignment value for some column in table", connection, transaction)
If Not transaction["SomeColumn"] = "Expected value for SomeColumn"
assert("ColumnName was not going to be updated to the expected value!")
transaction.Rollback()
Alternative To Transaction Lock?
Mar 20, 2012In my project i am using begin transaction commit or rollback changes. but this causes lock to the tables in that particular functionality.
So if the any other user does any other functionality those locked table are not available until the transaction is completed. I want to know if there is any alternative to transaction which insures data security but the tables are not locked out.
