I would like to generate a static URL based on a few parameters. The page serve the file for downloading is called CertificateDownload.aspx ,I am generating the download link in Report.aspx.These 2 files reside on the same physical folder.I do not like the replace method ,but I could not think of another way of doing it. How can I improve my code or what is a better way of doing it.
I need the absolute url to be displayed as text in the web browser.

Dim downLoadUrl As String = HttpContext.Current.Request.Url.ToString.Replace("Report.aspx", "CertificateDownload.aspx") + "?CertificateID=" + CertificateName HyperLinkDownloadLink.Visible = True HyperLinkDownloadLink.Text = downLoadUrl HyperLinkDownloadLink.NavigateUrl = downLoadUrl
I would like to generate my links automatically via a static class in each of my aspx pages (or in a common BasePage).Currently I use this:
private const string TEMPLATE = "~/One.aspx"; public static string Link () ( string link = String.Format(TEMPLATE); return link; )
But the name of my page, One.aspx is hardcoded. Is it possible to generate the path instead of this hardcoded constant TEMPLATE. You should know that I do not instantiate the class before creating the link.
I'm building an HTML5 application (with ASP.NET back-end) and i want to develop it in such a way that i can run it locally with all my resources (such js and css) not minified (so i can debug it easily). However when i build the final version i want merge and minify the resources. At the same time i want to create several versions of the app targeting different platforms (iPhone, iPad, desktop, etc) by adding appropriate css.
I thought that the final output should be a set of html files (so the get cached nicely). I could use ASPX and just control the output by a query string parameter, but i don't really want to have the form tag on my page.
So the questions are:
What are the pros and cons of using static html pages generated from a template versus a dynamic ASPX page? (apart from being able to run on any web server) If ASPX approach good enough then how can i get rid of the form tag that's required by ASP.NET?
UDPATE
Another factor in favor of static html pages is the fact that the files are served instantly, whereas ASPX may take awhile to load if the app has recycled.
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.
I want to access the static variable in my global.ashx file I am using classname.variable name for accessing the variable but the variable name dose not appear.Can someone tell me how to access static varialbe in *.ashx file.
I have an application I am trying to write that generates a text file conforming to a file specification, and the file could contain thousands of lines. This part is easy. The more challenging part for me is the user interface. It needs to be a web interface with various options to affect what data gets on the file; this part is no problem. The process for generating the file, though, could take a little time depending on the amount of data , and I would think the web page would time out.
What options do I have for the UI? Could I create some sort of service that the page calls and runs in the background? When the process errors or is finished, I'm thinking there could be an email sent out, or even messages displayed on the page.
i want to generate random URL for the users who want to download my file which is located in my server (http://servername/book/book.pdf) after he bought from us. and that URL should expire after few days lets say (1 week) .
I'm using ASP.NET (not that it makes a difference I think), but when I click a button in one of the tabs, is there a way I can re-select that tab when the page reloads. I was thinking of sticking the tab section in an UpdatePanel. I was hoping there's a way I could trigger the tab to reselect.
I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.
I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = ""; static void OnClientConnected(string clientId, ref Dictionary<string, object> list) { list.Add("a", "b"); // I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:- BaseController.clientId = clientId; } public ActionResult Handler() { if (something) { // use the static ClientId here } // Release the ClientId here, so it can now be used by other web requests coming to the server. return View(); }
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
TL;DR: Which is likely faster: accessing static local variable, accessing variable stored in HttpRuntime.Cache, or accessing variable stored in memcached?At work, we get about 200,000 page views/day. On our homepage, we display a promotion. This promotion is different for different users, based on their country of origin and language.
All the different promotions are defined in an XML file on each web server. We have 12 web servers all serving the same site with the same XML file. There are about 50 different promotion combinations based on country/language. We imagine we'll never have more than 200 or so (if ever) promotions (combinations) total.
The XML file may be changed at any time, out of release cycle. When it's changed, the new definitions of promotions should immediately change on the live site. Implementing the functionality for this requirement is the responsibility of another developer and I.
Originally, I wrote the code so that the contents of the XML file were parsed and then stored in a static member of a class. A FileSystemWatcher monitored changes to the file, and whenever the file was changed, the XML would be reloaded/reparsed and the static member would be updated with the new contents. Seemed like a solid, simple solution to keeping the in-memory dictionary of promotions current with the XML file. (Each server doing this indepedently with its local copy of the XML file; all XML files are the same and change at the same time.)
The other developer I was working holds a Sr. position and decided that this was no good. Instead, we should store all the promotions in each server's HttpContext.Current.Cache with a CacheDependency file dependency that automatically monitored file changes, expunging the cached promotions when the file changed. While I liked that we no longer had to use a FileSystemWatcher, I worried a little that grabbing the promotions from the volitile cache instead of a static class member would be less performant.
(Care to comment on this concern? I already gave up trying to advocate not switching to HttpRuntime.Cache.)
Later, after we began using HttpRuntime.Cache, we adopted memcached with Enyim as our .NET interface for other business problems (e.g. search results). When we did that, this Sr. Developer decided we should be using memcached instead of the HttpRuntime (HttpContext) Cache for storing promotions. Higher-ups said "yeah, sounds good", and gave him a dedicated server with memcached just for these promotions. Now he's currently implementing the changes to use memcached instead.
I'm skeptical that this is a good decision. Instead of staying in-process and grabbing this promotion data from the HttpRuntime.Cache, we're now opening a socket to a network memcached server and transmitting its value to our web server.This has to be less performant, right? Even if the cache is memcached. (I haven't had the chance to compile any performance metrics yet.)On top of that, he's going to have to engineer his own file dependency solution over memcached since it doesn't provide such a facility.
Wouldn't my original design be best? Does this strike you as overengineering? Is HttpRuntime.Cache caching or memcached caching even necessary?
I have a small web application based on asp.net 2010 that manages invoices.
After the invoice is saved, it should automatically generate a pdf file.
which of the following solutions would be fast and easy to incorporate?
Use Sql Server 2008 Reports Use Crystal Reports 2008 and Crystal Reports 2008 for VS 2010 Use itextsharp to create the pdf file Use XSLFO to create the pdf file
The point here is I dont know any of the above. Which one is easy and quick to learn and implement. Are there any other solution to achieve this functionality?
I'm new to c# programming..I'm using windows form application c# .netI have been given a .resources file. it contains 2 columns 1) key and 2) values.I have brought the contents of this file into a datagrid using dynamic table in between and using resource manager.Now i have to edit the value column in the datagrid and if i click on a GENERATE button i should create a new resource file and it has to be stored as a file. In the same way i should create many sucj resource file.
i am trying to generate a pdf file using itextsharp in asp.net c#.
I came across table concept in itextsharp n i am trying to use it ie my application. I am having the following problem while using tables.The pdf cell which contains Name of treasery the word treasery comes on next line. I am setting width for each cell. if i increase the width than also no changes come. The gap which is shown using arrow in below image remain as it is al the time. Why is that gap?How to remove that gap?I want a dotted line as a border to only one cell. how to do that?here is my code
PdfPTable line6table = new PdfPTable (3); float[] width = new float[] { 2.5F, 1.5F, 3.0F }; line6table.SetWidths(width);[code]....
I'm using Visual Studio 2008. I've added a control on a page but can't reference it in code-behind file. When I looked at the Code-Gen file, I didn't find my new control. It looks like Visual Studio didn't update Code Gen file to include my control. Is there a way to manually re-generate that Code Gen file?
Does anyone know how i would generate an XML string using an XDR or XSL file in VB.net getting data from a SQL database (or from an my vb.net object), or even point me in the right direction
