Lock A Record When Two Members Are Trying To Access It?

Jul 5, 2010

I have the scenario like this,

My environment is .Net2.0, VS 2008, Web Application

I need to lock a record when two members are trying to access at the same time.

We can do it in two ways,

By Front end (putting the sessionID and record unique number in the dictionary and keeping it as a static or application variable), we will release when the response is go out of that page, client is not connected, after the post button is clicked and session is out. By backend (record locking in the DB itself - need to study - my team member is looking ).

Is there any others to ways to do and do I need to look at other ways in each and every steps?

Using 'Lock' In Web Applications?

Nov 30, 2010

A few months ago I was interviewing for a job inside the company I am currently in, I dont have a strong web development background, but one of the questions he posed to me was how could you improve this block of code.I dont remember the code block perfectly but to sum it up it was a web hit counter, and he used lock on the hitcounter.

lock(HitCounter)
{
// Bla...
}
However after some discussion he said, lock is good but never use it in web applications!What is the basis behind his statement? Why shouldnt I use lock in web applications?

Visual Studio :: Navigate To Last Edited Line?

Jun 25, 2010

In VWD, we can customize-edit-command to your heart's content. But there is none for what I used to get in NetBeans or Eclipse: go to the last edited position (after 5 minutes of search for the correct spelling of some name in the page).I know there is Navigate Back, but I often need to do click [Navigate Back] 10 times to get to 'last edited line'.

It would be nice if I can navigate through the 'green bars' (Yes, it is very difficult to find out what are green bars, once you found out, you want to be able to visit each of these using next or prev).

Also where is the documentation or help ofr each of the some 50 edit commands such as 'go to Reference'.

ADO.NET :: How To Lock Down A Table From Being Updated

Jan 13, 2011

Is their a wayin sql server 2005 to change some type of setting on a data table so that it can not be updated or inserted into?

My problem is that I have a data table that is somehow being populated by an application. I have looked through all of the stored procs, views, functions and the C# code itself. I can't find out where or how it is populating a certain data table. So I figure if I can somehow make the table non updateable, then I can find out where the insert/update is occuring.

This would all occur in a test environment of course.

C# - Looking For .NET Lock Thread Method?

Mar 30, 2010

I'm developing an ASP.NET forms webapplication using C#. I have a method which creates a new Order for a customer. It looks similar to this;
private string CreateOrder(string userName) {
// Fetch current order
Order order = FetchOrder(userName);[code]....

The problem here is, it is possible that 1 customer in two requests (threads) could cause this method to be called twice while another thread is also inside this method. This can cause two orders to be created.

How can I properly lock this method, so it can only be executed by one thread at a time per customer?

I tried;

Mutex mutex = null;
private string CreateOrder(string userName) {
if (mutex == null) { [code]....

This works, but on some occasions it hangs on WaitOne and I don't know why. Is there an error, or should I use another method to lock?
