I am generating an output on a webpage in a format like this
({"1":"Jeff","2":"Tom","3":"Michael",})
For this, basically this is the code I am using
Response.Write("(" + "{");
//
for (Int32 i = 0; i < k.Length; i++)
{
Response.Write(Convert.ToString(k.GetValue(i)) + ",");
}
//
Response.Write("}" + ")");
Notice my output, after Michael" there is a comma which I do not want since this is the last vaue but this is appearing since , is in the for loop. How to prevent this/remove this last comma from appearing?
My output should be ({"1":"Jeff","2":"Tom","3":"Michael"}) (There's no comma after last value here)
I am using a compare validator, which validates that the entered number is a valid double and also validates it against a given value (greater than zero). I am validating money amounts. Because of the location where the app is used, the locale sets the comma as the decimal separator. The problem is that when a user enters the value using the numeric keyboard, the number gets written with the dot as decimal separator, and is rejected by the validation. I'd like to have this validation done before triggering a postback (like a customvalidator would) and accepting both separators.
Control from the AJAX Control Toolkit, but can find no way to make it use a comma as a decimal separator instead of a point. Other controls such as the [Code].... will automatically use the Page Culture and adapt their content according to it. Do anyone know a way to change the Decimal Separator?
I'm trying to format a data bound value as below, but I keep getting a space as the thousands separator, i.e. the displayed text is always "12 340.00" when it should be "12,340.00".
I recently read an article on making ASP.NET sessions more secure here and at first it seems really useful.
Previously I had been storing the user's IP address in the session, then making sure in every subsequent request that the requesting IP was equal to the stored IP.
The code in the article also protects the session by checking the IP address, except it stores a hashed message authentication code containing the user's IP as part of the session cookie. It creates a hashed MAC twice every request, which I imagine would slow things down a little.
I can already see a potential flaw in their code: if you were to somehow get a hold of the key used to generate the MAC, you could then generate a valid MAC with your own IP - you wouldn't even have to fake the IP the session was started on.
It seems like an overly-complex solution to a simple problem which not only incurs a larger overhead but also is more susceptible to attack than the trivial method - unless I'm completely missing the point.
So, why would this approach be any more secure than the more simple approach that I had been using?
As a slight aside, the author also states that you shouldn't use the whole IP address in the comparison, as some user's IPs change every request if they are behind a proxy. Is this still the case if you check X_FORWARDED_FOR?
I'm having issues with an ASP.net site (framework 3.5, IIS6 ) having very slow 'first hit' response times. I'm guessing that the issue is to do with the app pool recycling and having to warm up.
I got to thinking. As part of the site I have a HTTP module that spins up a 'never ending loop' on a separate thread which periodically (every 5 seconds) calls an sproc on SQL to make sure the database is still there. I'm wondering if a similar approach might work to get the site to make an HTTP request to "itself" as a keep alive.
My question is, before I go and do this, can anyone think of any reason why it won't work? For example, something like "oh no... ASP.Net will figure out that you're playing with yourself and not go through the whole page lifecycle... etc etc".
I have a web parts page in which each web part has its own personalization data(list of DB table primary keys). At startup, I want to get thecombined data stored in each web part to make a query in the background. Is it possible ? Currently I have to wait for IPersonalizationData.Load for each web part to get what keys are stored by each. Is there a way to store personalization data for the whole page ? I can't use profile as this data is not per user. Worst case is write to a file which I want to avoid if possible.
I have 2 points for today I. I have a controller in which i have a public static method for getting the details for a checkbox like
[code]....
is it ok for me to use this same function like this one in the view, so that I do not need to use the viewdata object,
<%: Html.DropDownList("country", new SelectList(UserController.GetCountryLists(), "value", "countryname", "0"))%>
Also i have another query, when i use the same id & name for the radiobuttons, validation at the client side is working fine.If I use the same condition for a group of checkboxes, i get do not get the checkboxes highlighted during client validation and only during server validation, i get the error message, but the controls [checkboxes] do not have a red border indicating the error.I have used my own html helper to generate the checkboxlist as per [URL].
I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes:
Serve static content from a cookieless domain (5)!
Here is my screen shot [URL] as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image?
Like many people using ASP.NET MVC, I've implemented my own custom 404 error handling scheme using an approach similar to the one described here: [URL]
(I actually discovered that post after implementing my own solution, but what I came up with is virtually identical.)
However, I ran into one issue I'm not sure how to properly handle. Here's what my 404 action in my ErrorController class looks like:
[Code]....
The part that's different from the answer in the other StackOverflow question I referenced above is how the 'retry loop' is prevented. In other other answer, the code that prevents the retry loop simply sets properties on a ViewModel, which doesn't seem to actually prevent the loop. Since the action is sending back a response code of 404, then accessing the action directly (by typing "/Error/NotFound" in the browser) causes an infinite loop.
So here's my question: Did I miss another, more obvious way to handle the retry loop issue, or is my approach a decent way to do this?
I'm building a page in asp.net that will use tiny mce to provide a rich text editor on the page. Tiny mce outputs the rich text as html which I would like to save to a database. Then at a later date, I want to pull the HTML from the database and display it in a page.
I'm concerned about allowing malicious html, js tags into my database that would later be output.
I should html encode/decode etc. to prevent a persistent xss attack and or sql injection attack?
I have a website I am working on and I am using the following code quite often to access the database:

I have a few buttons on one page that use something similar like this in the code behind. I have heard to look into ADO.NET but I was wondering if there was a quicker way then creating model and business layers etc.
i am using simple form in that i put 3 upload option when i click the upload button the 3 files are stored in to unique directory. but when i refresh the page once again again it store the file once again to the directory . how to fix this problemin asp.net C#
Various tutorials and articles describing the N-tier architecture use the "Open Late Close Early" methodology for Connection objects. The connection is just opened before a "ExecuteNonQuery or ExecuteReader" command, and closed immediately
This means that inside a transaction where a number of business objects have to be updated (using different DAL classes), the connection can be opened and closed many times.
In that case the transaction will be escalated to a distributed transaction. Now we can’t assume that MSDTC will be availableunning every where. Now if I am building a website to be uploaded using those shared web hosting services, which does not allow MSDTC , what are my options ?
I have code in an ASP.NET form that needs to, depending on user entry create messages in the database. We are speaking of potentially thousands of db entries. How do I protect against deadlocks, I mean apart from using Transactions and setting IsolationLevel to Serializable, as well as using WITH(NOLOCK) statement on my select statements since I don't mind a dirty read.

I have an asp.net page that will be doing some processing that may take a very long time to complete. I cannot just set the page timeout value since this is going to be in a hosted environment and the timeout values that I set in my web.config are overridden by the server host. What I'm doing is taking a file from a FileUpload control and doing some web requests to a 3rd party service for each line in the file, all of which may take a very long time to process a large file. I'm talking on the order of, say, 30 minutes, and there's just no way to optimize this any further to cut down on the processing time. Is it possible to even do such a lengthy page request in asp.net? Can someone give me a pointer in the right direction here to make this happen? Is my only hope to create an async page? It seems that doing an async page is the way to go if I have a potential for a lot of lengthy requests, but really this massive of a request is going to happen VERY rarely so this is not an issue of running out of thread pool since most of the time this particular request will be completed relatively quickly, but on occasion it may receive a very large file it will need to process and will take a very long time. So what is the best way to handle that case?I'd also like to update the client with the processing status as the processing is going on. I'm familiar with doing client ajax calls via jQuery to a page webmethod so if there is some clean way to update the client as this long processing
I'm trying to use DetailsView of asp.net to display data in the following format:
Name: Adam Age: 18 Gender: M
And I wanted to add a lines (gray image) between each two rows
Name: Adam Age: 18 Gender: M
I managed to put the image as another row between each two rows, but it make it start only on the second column (of the data) because the first column "saved" for the header (which is empty)
anyone knows how can put the image between the rows and make it "use" the whole line?
I'm developing a web application which get number with decimals. When I write 0.08 the rangevalidator understand 80 and it doesn't valid it. It does well if I write 0,08.The most extrange is In the develpoing computer and in the client computer I have the point as decimal separator in regional settings.Where can I change the decimal separator por rangevalidator in the cliente computer?
