My page is loading to slowly, i am loading information from 2 giant dataviews, to get infromation about sales history, into a table. I am loading the information based on yesterdays sales/numbers.
I want to cache the data, but how could i do it if my query depends on the year selected, and the information the user wants. I was thinking it would be best to cache the pages.

I have experienced this in both VB 2005 and 2008. First, design a form by placing your UI elements where you want them. Then, go back and start naming your controls the way you want them (i.e. "txtWhatever" instead of the default "TextBox1", etc.).I find that after you change the name of a control, there is a slight but annoying delay as VS IDE digests the fact that you changed the name, thus slowing down my workflow. I recall that this process was much more rapid-fire in the VB6 days - i.e. name one control, click the next one and start typing, boom-boom-boom.
Has this annoyed anyone else, and if so, have you found any kind of remedy to speed things up in this regard?
I have a datagridview that takes time when loading, and once loaded, is also very slow when using the scroll bar to see the other rows.[code]..
View 12 RepliesI have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.
What we want to do is save an entire control into Cache and recommit the properties on page load, including data items. But we'd like the controls to exist already in the page.

I'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?
I have a VB.Net project that creates a new Webbrowser instance which then navigates to a page in order to read the HTML into a variable ( then modify this before displaying in a visable webbrowser).The issue i have is that the webbrowser navigate just reads the page from the cache and does not read it from the server.
View 2 RepliesI have a few subs that run under Webbrowser1.document completed section of my app I know the code words because I tried it out using a new project and tied the code to a button and it works great.

View 3 RepliesI 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 master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.
View 16 RepliesI 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?

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.

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?

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.
View 3 RepliesHow can I clear my cache using VB.Net? I'm making a web browser, and this function would be nice. I've tried this to no avail:
Response.Cache.SetCacheability(HttpCacheability.NoCache);
You'd think both are the same. But maybe it's the compiler that Microsoft has used, but I've noticed that when compiling two very small programs, identical logic. VB.NET uses more IL instructions.Is it true than that c# must be faster, if only because its compiler is smarter.
