I'm building a browers-based game that will need to constantly be updating EVERYONE'S accounts regularly; what is the best way to go about doing this? Creating a process that runs every time someone goes to a page on my site slows down the load time immensely. Do I need to create a windows scheduled task that calls this/these process(es)? It will need to constantly run.

Lets say I have a web service installed on ServerA. I also have a web application hosted on ServerB, completely different domain from ServerA. That web application contains a web reference to ServerA's web service, so consumes it. What happens if the WAN connection between ServerA and ServerB goes down, for whatever reason? I'm not clear if, once the web method is coded into the consuming application, that the server hosting the service has to be constantly available or not.

View 2 RepliesI would like get some hints reagding my application. Acctually I have a text file which is on Server and updated daily. After I parsed my text file, I would like to update my database according to the text file's data. I'm wondering how I can sepcify the input to SqlCommand so that my table should have the text file's input and then update the values.
View 8 RepliesTrying to figure out how to handle data returned for a site search from a description field. I don't think I want to display all the text from the description field, but I also don't want to "chop" a word in half. How do I get the first 100 characters, plus a few extra letters if needed to prevent a word from being chopped in half. In some cases, the description field is less than 100 characters, so all the text will be displayed. However, if the description does need to be chopped at 100, I'd like to finish the word and add ... to indicate that there is more text.
View 6 RepliesBasically I have a site where I want the user to input something, have it go to the server for processing and then return it asynchronously, load the contents into a div and then fade it in with jQuery. What is the best way to the do accomplish this?
Currently here is my "solution":
$(document).ready(function () {
$('#output-box').hide();
$('#form1').submit(function () {
$.ajax({
type: "POST",
url: "Default.aspx/ParseData",
data: "{ $('#txtInput').val() }",
success: function (msg) {
$('#output-box').text(msg).fadeIn();
}
});
return false;
});
});
It doesn't work - just returns the contents of Default.aspx. So how do I properly send the contents of #txtInput to the ParseData function in Default.aspx.vb? Also, is this the best way to accomplish something like this? Should I even need to use jQuery to send the data, or should I simply call the function and have it grab the data server-side, put in the information in the result div, and then show it using jQuery?
I have a question, and I don't really know what forum this would pertain to, so I'll ask it here. I'm looking to build a website application that uses data stored in a SQL Server database. But I want to be able to constantly pull data from a source 24/7 (all the time). Obviously a typical website application, unless a user is browsing it, won't be active and running.
How could I go about this? Would this technically be using a "service"? Would that always be running and allow me to programmatically pull data constantly throughout the day?
What is the best way to update data constantly on the client using asp.net Timer + Update Panel, or I need to use Reverse AJAX for that?
View 3 RepliesI'm quite new to MVC, and only now i got hands-on with Ajax and Jquery as well.I've been reading a lot on blogs and forums, but can't seem to find the exact answer to my question.Here's what i want to do:1) Simple file manager View, where user can upload the file2) After successfully uploading, user is redirected to other View3) Meanwhile, the server starts processing the info existing on the file just uploaded. I want to be able to update the View the user is viewing, with the actions that are being performed on the server. Example (like stages): Reading File, Converting File, Parsing File, etc...4) When all stages are completed, i can show the user some buttons or whatever (until then, he has access to nothing...just view the page changing and processing)So....First, is this feasible?If so, how?I tried many approaches with AsyncController but can't seem to achieve nothing good.

The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?

The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.

When I open my web page with my RadEditor version 7.3.6.0 on it to create a new using the editor I get a popup warning on the page.
Soon after this while using Rad Editor I get a message in IE8 (Version 8.0.6001.18702IS) saying the page has been recovered and I have lost all of my edits.
This is also happening to other people, my customers, when they use the same page on their IE browser.
I have an image in a report (a school logo stored in a folder).
My issue is that this image does not appear constantly on my reports, all of which use the same code to load it.
The image is stored in a Blob in an unconected dataset on the report.
The data set is filled as follows
public static DataTable SchoolLogo()
{
string ImageFile = System.Web.HttpContext.Current.Request.MapPath("~/Images/ReportImages/logo.jpg");
DataTable data = new DataTable();
[Code]....
I have about 6 reports that use this code and the image is loaded sometimes and sometimes it is not (even within the same report if it is loaded several times.)
I just upgraded from VS2008 to VS2010, and now my web deployment project keeps rebuilding constantly. Even if I have a WinForms application set as the startup project and hit Ctrl+F5 to run it, the web deployment project rebuilds every time I hit Ctrl+F5. It didn't do this in VS2008. Does anyone know what's causing this?
View 1 RepliesI'm trying to make a Web Page in ASP.NET that functions like a TcpListener or a Socket so basically you could "connect" to other people accessing that Web Page.
It also can't be a constantly running program that's accepting clients and would crash if the program was closed.
Just wondering if this is possible and where to look.

View 1 RepliesI'm having a strange problem - probably has a simple answer but, I haven't been able to find it or figure out the cause. I'm hoping someone has had this same problem and figured it out.
Basically - my application works great on the development machine. So I copy it over to the server and it works great. Come back the next day and my GridView is only displaying the first record...I then log into the server remotely and open the web page on the server and all records are returned, so the application works fine on the server. I then return to the local machine and now the application is returning all rows in the GridView. So, weird but, what whatever, it works. Go away and come back again the next day and...
1 ) Only 1 record from dataset is displayed in GridView
2 ) Log onto server remotely and view webpage on server --> all records now display
3 ) Try again on local machine, now application works fine...grr. What am I doing wrong here? Using Visual Web Developer 2008 on Windows XP. Querying SQL Server 2000 (I know, I should switch to 2005 and use VWD 2010 - but ouch, really!) when a text box value changes (Vendor_PO_TextBox.TextChanged)

I'm using Visual Studio 2010 and working on an ASP.NET 4.0 web application. At the moment, a co-worker and I are tweaking CSS, which means constantly changing and saving CSS files and then refreshing the running page in a web browser.Every few saves, the application restarts, causing a considerable delay while we wait for the app to start up, log in again, and return to the page we were working on. In an IIS production environment a CSS file wouldn't go through the ASP.NET ISAPI, but apparently when running with VS2010 and the developent web server this doesn't matter... or something.

My company is planning on having some planned down time, because of some server migrations. Their are about 20 different web applications (internet, and intranet). Any of which can go down at any one time because of the server migration of applications.
So, does anyone know if their is a way to provide a generic message to users if a particular application is down? Like a popup message box, or generic page for that particular application? The idea is to not write 20 different popups or 20 different Fyi-Web pages. But one single page or popup informing that the application is down.
i want to know if i want to use multiple server for my application. what should i do.e.g. if i used session to store some important data so as session get stored on server if my application use one server and server get crashed then my application also get crashed. So to avoid this problem what should i do (if solution is use multiple servers then how can i do that)
