C# - Code To Be Run Automatically When The Request Is Finished?
Oct 15, 2010
I have my own SQL based session class. I want to automatically commit the data in the session at the end of program execution (i.e. at the end of serving the page request). Do object destructors (finalizers) not get executed at the end of every request? Is there anyway of doing this instead of having to explicitly call a Dispose() method every time I am done with my session object?
I have a button that needs to check if a contact exists.I have used the Jquery ajax function to do this and I do successfully gind out if the contact exists or not.However I cannot find a way for the javascript code to wait until the ajax has finished so I can return true/false to the button for it to continue server side function. I.e.
I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:
protected void lbtnAddOption_Click(object sender, EventArgs e) { SelectedOption = new Option() { Account = txtAddOptionAccountNumber.Text, Margin = chkAddOptionMargin.Checked, Symbol = txtAddOptionSymbol.Text, Usymbol = txtAddOptionUsymbol.Text, }; Presenter.OnAddOption(); // Insert the new item RefreshOptions(); // Pull down and re-bind all the items mpeAddOptionDialog.Hide(); // Hide the modal // ... Make call to jQuery scrollTo() method here? }
This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:
I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.
The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:

Is there a way to trigger a piece of code to execute at a certain time once a week?
I basically want my website to send out a reminder email every sunday. I have a function called SendReminder() and I would like to know if it is posible for it to run by itself because at the minute I have to press a button to run it.
I am working on an ASP.NET project. When I am debugging, I often want to switch back from my browser to Visual Studio (2008) and edit some code. Visual Studio then won't let me edit the code, unless I explicitly quit debugging first.
Is there any way to configure Visual Studio such that is automatically stops debugging and allow me to edit the code, or do I have to stop it manually each and every time?
Disabling Edit and Continue does allow me to edit the code, but this does not force VS to stop debugging...
So I am a beginner with .NET, Visual Studio, C#, etc. But I am wondering something about the code behind a form and a difference I am seeing in 2008 versus 2005. So lets say I have a simple Windows Form app, C#, and I throw a couple controls on it. Then I add some MessageBox.Show event handlers for the default events....in 2005 there is that little section within the code that is hidden that basically contains the code that 'registers' the controls with the system....I think. That may be a bad definition?? Basically I think that automatic code generated here just basically associates the event to the event handling code....anyway.
I can see this is 2005 (once I click the like gray box), but it does not appear anywhere in 2008. So this has to exist somewhere, and I just wanted to ask to be familiar with what is going on since I am new to this. I still have to figure out how to turn on the code line numbering in 2008, but I can google it.
How to generate a employee code in textbox automatically while in run time in web application.......when i run the page it will check the employee code in the database and it automatically shows the next value in the textbox how?
This may be due to a lack of understanding of what's going on under the hood or simply a lack of understanding of threading in general. When a user logins I need to run some tasks that call web services to update data in my system. Since the services could take a considerable amount of time I thread the entire process. However, even though I think I'm running the whole series of tasks in a thread separate from my application, my application waits until the called function is finished before it proceeds.
I have a page that has a note to the user about the file they're about to download and a button to click to start the download. When they click the button, it does a Response.Redirect to another page with the following code in its Page_Load:
I want the download to start and then I want this page (which is a tab in the browser) to close.
The code to download the file works fine. I just can't figure out how to close this tab when it's finished. I understand that Response.End means that I can't put any more code this page; it will be ignored. But how do I get this tab to close?
I'm writing an ASP.NET webapp that will copy the contents of a CD to a network share. I need to check periodically if the copy job is finished.
One way of doing this is checking the network share folder to see if the file size has changed since the last check, but that seems kind of dodgy. Does anyone have a better idea how to do this?
EDIT
some more explanation: Basically I'm calling a JsonResult action method every 5 seconds, called getStatus(source,destination). This method needs to check the following:
- if the source dir is still empty, copy cannot start --> return status "waiting"
- if the source dir contains files, copy can start -_> call copy method + return status "copying"
- if the destination dir contains files, and file size stays the same, copy is finished --> return status "finished"
I have a webpage with two usercontrols. Usercontrol1 displays the time and the Session["Username"]. The default Session["Username"] is 'guest', which will change as soon as you are signed in. Usercontrol2 is the sign in form. The webpage doesn't cache so everytime you should get a "fresh" page?
The follow happens when a user signs in: In usercontrol1 the Labeltime gets updated but labelWelcomeUsername doesn't.
I am working on a page where we have a form that the user is filling some information in. When the form is submitted I want to process the information and then redirect to an external server. The catch is that I need post data to go to the external server so a redirect will not work.
Is there a way to programmatically submit a form request with post data?
For the sake of a ridiculous example let's say on http://A.com I have an asp.net page with two inputs that accept numbers and a submit button. When the button is clicked I want to send a post to http://B.com with a post data parameter "AdditionTotal" which contains the sum of the two numbers entered.
Im dynamically generating an HTML Select Box, lets call it myselect. Im creating this select box based on some database values Im generating an HTML Select Box.. almost like a string that Im just spitting out to the page. So it's never a control in the codebehind, just part of a string thats rendered as HTML by the browser. If I submit my form, and in my codebehind I perform:
Dim myVal as String = Request.Form("myselect")
That code will give me the VALUE of the myselect select box. How can I refer to this control to cast it as a System.Web.UI.HtmlControls.HtmlSelect control? Request.Form seems to give me the value, but I want to reference the object itself..
I hav button on a page. click on it and it works on local system. when i deploy on server. code seems not working. I receive a 'request failed' and truest level error. method even contains 1 simple stmt of 'exit sub'. it's not happening on other pages.
I am trying to use ThreadPool.QueueUserWorkItem to send daily newsletter to my website subscribed members (about 500 members) at 2:00 am every day automatically.I placed record on txt file everytime send out email for debuging, then I found that only about 165 members been send out. every day is different number but just about.never finished whole 500 members.looks like thread aborted before finish sent out all emails.anybody knows what's going on here?I am using shared hosting, so I couldn't run my own window service for this.
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
