I have an application that allows users to bid on items that are put up in an online silent auction type of deal. Currently, When a user clicks submitBidButton, the application stores the bid in the database, and then updates the price. Sounds simple? It was.. until it got popular. If there is a bidding war on the page, my application, and SQL database start crying.. literally.
About consuming the data with jquery/JSON.. and WebMethod. It works like a champ. BUT. How can I take advantage of Caching to increase the performance of my application? SQL Caching? Asp.NET Caching?
Each member places a bid, and I want to add a ajax timer that calls back to the server every .5 seconds to see if a user has placed another bid. The app was built in vb.net.
I have 2 dll files from a third party, and they have the same name (v7 and v8). My program needs to be able to use both of these dll's (meaning wether the enduser has a lisence for v7 or v8 of the thirdparty dll, they can still use the program). But I am stopped from referencing both of them as they have the same name. How do I resolve this? Searched the web and found info about sn.exe and strong names, but can't find a good explanation of how this works. Anyone?

I have a function GetAllProducts() which fetches all products from a database and stores it in the cache for future requests. This works fine, but if I then call the function e.g. ProductSearchResults = GetAllProducts(), and then modify ProductSearchResults variable, this also modifies the cache, which is very important this never happens, as the cache affects the whole website.
I understand this is because both ProductSearchResults and the cache now have the same reference, but how do I solve the problem? Is there something that I can put in GetAllProducts() to ensure the cache always uses its own value?
CODE:
If you build and deploy UserControls, Components etc do you give them strong names and put them in the GAC or do you simply place them in the same folder as the executable?I've made a component that will be given to other developers and they will, in turn, deploy it with their own applications. If I give my component a strong name and install it into the developer's GAC then I assume that the developer using my component will also need to place it in 'his' customer's CAG when he deploys his own application containing my component.

View 2 RepliesTwo separate but related questions about deploying a Visual Basic 2008 .net application:1. Click One installs in a cache under local data. The EXE launches from the cache even if not on-line. I don't want my users to have a runnable EXE left over in their cache after exiting the program. Is there a way to delete or disable the cache contents on close of app or equivalent?
2. My EXE uses an interop DLL. I want my EXE to be a single stand-alone file so that I don't have to copy both the EXE and the DLL to the user. Is there a compile setting to incorporate everything, includng the DLL, into the EXE.First question relates to Click Once Web deployment. Second question refers ONLY to ordinary COMPILE, not click-once.
I am currently developing a advanced web browser in Visual Studio 2008. I was reading information about a browser i currently use, it said that the browser goes faster thanks to a "advanced cache algorithm". I was wondering if it was possible to implement this into my web browser, and if so how would i do so? I am using Visual Studio 2008 writing in .Net.

I have a form intended to generate serial number and this serial number will be distributed to the other forms. I use to pass the serial number to the other forms this way:
if frm1.visible = true then frm1.txtserial.text = frmserial.txtgenserial.text
if frm2.visible = true then frm2.txtserial.text = frmserial.txtgenserial.text
if frm3.visible = true then frm3.txtserial.text = frmserial.txtgenserial.text
and so on....I want to have a method that will ease the method above. Is there a way to declare a txtgenserial textbox globally and the other forms will just refer to it?ex. Public genserial(tb as textbox)' that example is only a demo to what I wanted to get, this declaration is absolutely incorrect.
I'm writing a program that uses a webbrowser to update a page and gather its data. But it's reloading the page from the cache. I located the cache and quickly found that it cannot be deleted like normal files.
Now i really only need to delete one file, specifically a javascript file, because that's the only thing i need updated. But deleting the cache is proving to be a bigger problem than i thought, let alone deleting a single item from the cache.
I was thinking is there a code that I can use to get the Internet Explore cache? Can I use the Environment method?
View 3 RepliesI'm designing a solution that involves a windows service running on a server that will have multiple clients requesting data from it. This windows service needs to read a few short details from some text files on the server, however there could be anywhere from 1000 to 100,000 of these text files. I've already written my code that goes through each of these files and extracts the relevant information from them and populates the properties of an instance of a custom class, then adds the class to a list. The problem is that if there is a large number of these files then looping through them all takes a long time and there are constantly new files being created and deleted in this folder as well, so I have designed the following system:
1. When the service starts it goes through every single file and gets the data I need from each one and writes it to an XML file (just one XML file that holds all of the info for all of the files, not an XML file for each one). It also stores the file name with each entry and then once it has done this loop through all the files the first time it goes through the file paths in the XML file and checks to see if this list of files is the same as what is actually now in the directory (as new files may easily have been created during the initial scan process). I figure this shouldnt take anywhere near as long as the initial scan because it is just checking to see if the same files exist, not reading data from all of them (although it may read data from the 50 or so that might have been created while the initial scan was running). 2. Once it has a list of files in the XML file that is the same as the real list, it starts a FileSystemWatcher to watch for any new files being created/deleted. 3. If the FileSystemWatcher finds a new file then it reads the info from this file and adds it to the XML file. So now when a client requests data from the service, the service just reads through the XML file and basically returns the entire contents to them. This should be much faster than the service reading through every single file every time a client requests data.
All I want to know really is - does this sound like a decent design? One problem I am curious about is what will happen if a client requests data at the same time as a new file being created, because the service will be trying to read from, and write to, the same XML file at the same time... I guess one way around this would be for it to check for a file lock before it tries to write the data and just keeps trying until the file isnt in use (say every 5 seconds or something)
I am using WCF for the communication between the client and server and WPF for the client side app.

View 6 RepliesI've noticed that when I Response.Redirect to an .aspx page, it sometimes displays a cached page instead of actually executing the page and pulling fresh data from the database. I'm not using output caching or anything special in .Net here -- this is a CRM, and the caching is either happening on the client or, perhaps more likely, automatically in IIS. There is never a querystring involved, by the way. I'm passing a key via session. I know that if I used the querystring it would probably partially bypass the cache problem, but it's not an option in this case.
I did a little digging, and some people get around this by using Server.Transfer (which actually behaves differently than Response.Redirect and some of the details are not always desirable), and some other people said to set Response.Cache.SetCacheability(HttpCacheability.NoCache) on the page where I want to avoid caching. I thought .aspx pages were always flagged to avoid caching. Right?
