C# - Enforce Transactions For Write Operations In SQL Server?
Nov 16, 2010
How do I ensure and enforce that all write operations to my MS SQL Server DB are transactions-based?
The reason I want to do this is that the DB contains financial account data and operations that fail halfway through some set of changes should not be able to mess up the database by mistake or by crashing.
The application is written in ASP.NET C#.
Edit:
There is a DAL but it does not (yet) require transactions for changes.We wrote the DAL ourselves. We did not use ORM.
I know how to perform one transaction from ASP.NET.
I want to ensure that all changes are made in transaction form so that if the application throws some exception in the middle, there will be no change to the database.
for some SQL queries I know the expected number of rows that must be affected by UPDATE, DELETE or INSERT statements. It could be a number such as 1 or a range such as 0-1 or 1-2 etc.
What is the best way to enforce that this is the number of affected rows and that otherwise an exception is thrown?
Also, can I limit the number of rows affected for UPDATE/DELETE/INSERT to say 1 row and otherwise get an exception?
I'm trying to extend the GridView into a custom/user control "WorklistGridView". And I'm not quite sure how to do it... so here's what I need:Every row needs to have a control (either a boundfield or a templatefield with a label, etc.) that contains the StepID (which is a column returned in the data set).I want to be able to use the WorklistGridView as a base class and extend it to something like "XyzWorklistGridView", where that child class would have a few more controls in the row template.
I recently purchased a new domain for the sole purpose of hosting all the static content on a separate server and delegate CPU intensive operation like thumbnail creation on a different pool. Now I would like to do some operations on images uploaded to that remote server : creating thumbnails or updating the image if we need to. Should I download the images to my server, modify them there and then upload them back to the remote server or should I try to create web-services to manipulate the images?One of my solution was to provide an interface to upload and manipulate the images in the new domain, by leaving the old domain when it comes time to work on images, but I find it kind of awkward.I would like to keep the new domain cookie free. How would that affect my ability to restrict any random user to use the web-services if I decide to go that way?
Today my client has asked me to do Data Base Log,that is if any change done like,Insert or Edit or delete that has to be viewable in Log Report,if somebody did even a Small change that also has to be keep track and has to display in Log Report,like the recent activity is so and so and so and so person has done this.
I want to enforce some calculation to my project, my requirement as follows. I have txtQtyReq,txtQtyyRec,txtQtyShor(All are 3 textboxes) on load all the 3 textbox/columns should show as "0".(QtyShort=QtyReq-QtyRec)I need to calculate/implement this in txtQtyShort column. when i give a value in txtQtyReq as "50" ,it should calculate QtyShort and display as 50.
txtQtyReq txtQtyRec txtQtyShort(=txtQtyReq-txtQtyRec) 0 0 0 50 0 50 50 20 30 txtQtyReq=Quantity Required txtQtyRec=Quantity Received txtQtyShort=Qunatity short
I have checked Enforce Referential Integrity in my relationship section in my access database.By this way Can I delete child records when I delete the perent record?
I had no problem with this in Visual Studio 2008 but it seems that VS 2010 is having an issue, and I'm betting it's probably me.I have a solution with an ASP.NET Web Site Project and a few C# projects (BLL, DAL, Tests in NUnit). I have configured the build process for the test project to automatically run NUnit to run the tests. I would like to ensure that the BLL and DAL projects build before the test project so that the tests will run against the latest compiled version (yes, I know I could do this all in one project, but I'm choosing not to -- please bear with me :) )
So, I set the dependencies of the Test project to include the BLL, DAL, and Web Application projects, and the build order shows BLL, DAL, Web Application, and then Tests. However, I noticed that the BLL doesn't actually build when I build the Test project.Any idea what this could be or any option I might be missing to force the other projects to build when I build the Test project?
I have a website running on iis 5.1 with asp.net 2.0. Where in the windows registry can I change the requirtements for some the security features? For example, I do not want to enforce strong passwords and I do not want to use the secret question and answer features.
how can I create stored procedure and write my select statement in it, I know how to create dataset then put type stored procedure and assign it to the sp ... what I want is writing my sp... how can I make it ?
check the following code, this is what I want to write put I don't know where or how !
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?
I have to write a application which connects to remote server(windows 2003 server, open SQL Management studio in that server and enter a specific SQL Server address and access a stored procedure, change some values and execute the stored procedure.)
I have to write this application using C#.Net , Could anybody point me in right direction, Where do I start?
I have two databound controls on one page. GridView, DropDownList. My page is crashing with a SQL Transaction deadlock victim error. I would like to capture this error, and attempt to re-databind the controls. My first thought was to handle an event on the controls that allow me to do this, but I don't see which event to handle. I couldn't search any answers. Where should I begin?
I am a web developer handling back end frond end both.My question is that which transaction should I use to maintain ACID. whether transactions in Sql Server or transaction in Ado.net?
Are there any transactions around multiple webservice calls.Let me start with a commonly used example -- the travel agency. A customer intends to create a travel plan through an online travel agency. To do this, the online travel application calls the following three Web services:
These three services are available from three separate vendors. If any one of these three services fails, the customer does not wish to proceed with the transaction (again, either all three services must succeed or none at all).My language programming is Asp.net c#.
One is adding Userdetails(Fn Name : AddUserDtls) and another one adding address details(Fn name : AddAddresDtls) based on UserName which will get added after execution of first method ie AddUserDtls.
Problem I am facing is :
I have a single transaction and in that I have all the methods.
After the execution of first method,with out commiting i will go to second method.
and if any error occurs in second method.
I will rollback everything including the changes made by first method also.
Here one issue is there.
Since I am not committing the changes made by first method,
While I am executing the second method I am getting error that 'No user Name exists'
I understood that if we commit the transaction before the second method starts ,it will solve the issue.
But then it creates another problem.If some problem araise in the second method,then I cannot rollback the changes made by first method since it aleready commited.
I am trying to delete three related objects on one submit. Delete fails on one of the child objects, because of foreign key contraint with another table, It deletes one (the parent) but not the two child objects. All in one SubmitChanges(). I even used the TransactionScope, still same thing. So here is the scenario:
I have an object called Page which has a collection of objects called Webinars. There is another object Called Product which is one to one with Webinar.
i got an requirement where in the user submits the database scripts,stored procedures ,triggers ,functions or packages.i have create those in the database .if it throws an error it must be roll backed.how can i achieve this.
I have a DataSet that I have added to my project where I can Insert and Add records using the Add Query function in Visual Studio 2010, however I want to add transactions to this, I have found a few examples but cannot seem to find one that works with these.
I know I need to use the SQLClient.SQLTransaction Class somehow. I used the Add New Data Source Wizard and added the Tables/View/Functions I need, I just need an example using this process such as How to get the DataConnection my DataSet has used. Assuming all options have been set in the wizard and I am only using the pre-defined adapters and options asked for in this wizard, how to I add the Transaction logic to my Database.
For example I have a DataSet called ProductDataSet with the XSD created for this, I have then added my Stock table as a Datasource and Added an AddStock method with a wizard, this also if a new item calls an AddItem method, if either of these fails I want to rollback the AddItem and AddStock in this case.
I have a requirement to log all/most forms authentication transactions that take place within my page. For example, if someone is kicked out because of forms authentication, I'd like to get their username, time when kicked off, and where this happened. Is there a good way to do this. Better yet, has anyone done this already and is willing to share some code or post a link?
