Can I code to add transaction for some subs? If there is an error in any sub will roll back.For example, sub1 delete some tablessub2 insert data into tables which just be deletedsub3 send out confirmation emailsub4 make submit button disable
View 3 RepliesI have written several queries under one single transaction. When any of the query throws an error then the whole transaction should rollback. However, in some rare cases say 2% cases even after the error the next transaction is getting comitted.
note that all transaction processes (opening, committing and rollback) is done through .net.
I am using 64bit windows 2003 for data and application server. And website is configured for runapp32on64.
I have a transaction that has 5 update statements.I am checking that the data is the same as it was when i selected it before i change it, as this will be from a web app that many people could update.
I want to check that the rowcount is 1 everytime i make an update, if it is one then I want to move on, if not I want to rollback and return.
Here is what I have, only it it rolling back on the first attempt everytime.
[Code]....
I am not sure if rowcount is available yet, if not what do I need to use to find out if anyrows are being updated before moving on?
I was facing some serious deadlock issues in a high transaction table.For some select statement i have added nolock .But for few i can not put nolock, as i need accurate data.this select statement becomes a deadlock victim at times.

View 1 RepliesI'm doing a transaction type that is similar to iBank where people can add their payee. In my SQL database, I have a transaction table which has the date variable. I would like to set in a way that if the user did not express interests to activate the payee, the record will be expired after 1hour.
SELECT @Date = GETDATE()

I'm getting "This SqlTransaction has completed; it is no longer usable" exception when try to commit my transaction after sqlreader is close.Here is the code sample
[Code]....
...so when I get to commit the transaction it raises the mentioned exception: "This SqlTransaction has completed; it is no longer usable". I have also noticet that Command.Transaction becomes NULL after reader.Close()My question is: Can I use SqlDataReader and SqlTransaction ? Maybe to use BeginExecuteReader and EndExecuteReader ?
Does a DB transaction get automatically rolled back during exception or we should explicitily write transaction .Rollback inside the catch block to rollback a transaction...

I've got an odd problem and can't figure out what's causing it. We've got 2 different DataSets in the same project and I'm seeing different generated code from the MSDataSetGenerator. Both projects are .NET Framework 4.
In one DataSet, I can open the .Designer.cs file and there's a line like:
[Code]....
This essentially exposes a Transaction property to any partial class I create so I can do with it what I want (by setting it to something).
In the other DataSet no matter what I try to do, this Transaction property never gets generated. I've right-clicked on both DataSets and chose "Run Custom Tool" to get them to regenerate (I've even tried deleting the .Designer.cs file before doing this) and they both get generated the same.
I tried to make sure all the properties of the DataSets were the same. Both are using .NET Framework 4.0 and VS2010.
The file that does not generate the Transaction was from a .NET 1.0 asp.net web site that has continually been upgraded through different .NET versions. Right now it's at 4.0 but I don't know if that would have anything to do with it.
I have a stored procedure which is part of the aspnetdb but i am using my own database and therefore these stored procedures are added on my sql server locally.So i uploaded the databases to my hosting company 1and1 and created the stored procedures and tables as those in aspnetdb but i get the error as in the title. this is a standard stored procedure which lives in the aspnetdb database but not sure why this is happeningthe code is below which is for aspnet membership createuser a standard stored procedure

I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old
How do i call a variable in different subs on the page? I know I need to create a Private_Sub....? But I don't know the how to complete it. For example, I have the following code in a Button Click event. But I also need xamount in a different Button Click for the same page. Like I said, I believe I need something like a Private_Sub or Protecetd_Sub (not sure which one and why) with a made up name to reference it....like Private_Sub subXAmount, but I don't know how to complete it and then reference it.

I hope this is simple but I can't find any information when searching Google about passing a variable between two Protected Subs.
When I use the fileUpload tool within my webform I need to take the filename chosen and use it in a different Protected Sub

I'd like to know how to declare a variable in my code behind page that I can use in all the subs of my code behind.
I tried in after the Partial Class declaration to declare a "Public String" :

and to use it in my subs but when I use it from a sub to another I loose the value affected in another sub.
Is there a way to use a Public variable from a sub to another (I'm actually using a session variable in order to do it and I'm not sure it is the best way)

I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."
