  • Load page for validation but do not display it to user in ASP.NET

    - by Kevin
    We have a site requiring users pay $2 to view the details of a record. We occasionally get complaints because we send them to the payment page, and once they pay it turns out the record isn't valid, or it was lost, or the data couldn't be generated. So we want to add in a check to ensure the page constructs properly before the user is required to pay for it. However, we don't want the user to have access to the page until they pay for it. Is there anything in ASP.NET 3.5 or just general web design that would allow something like this? The data on the record is real time and computed on a backend server before sent to the client. Occasionally this computation fails for whatever reason. Our alternative is to call all of the loading methods and validate the data, then redirect them to the payment page. The problem is A) this will be a relatively involved process rewriting all of these methods to return validation information, and B) it still doesn't guarentee us the page will load properly. Any thoughts?

  • wordpress mu image speed problem

    - by InnateDev
    I have an mu install with the typical blogs.dir folder storing files for each blog. When loading these images however they take forever to appear, but they eventually do. It seems that wpmu uses php to serve each image which is ludicrous. When using images from the same domain but in a root folder, the images are displayed quickly. Is there a workaround the blogs.php for rendering files? Could there be something else wrong in the settings of my install?

  • Poor performance / speed of regex with lookahead

    - by Hugo Zaragoza
    I have been observing extremely slow execution times with expressions with several lookaheads. I suppose that this is due to underlying data structures, but it seems pretty extreme and I wonder if I do something wrong or if there are known work-arounds. The problem is determining if a set of words are present in a string, in any order. For example we want to find out if two terms "term1" AND "term2" are somewhere in a string. I do this with the expresion: (?=.*\bterm1\b)(?=.*\bterm2\b) But what I observe is that this is an order of magnitude slower than checking first just \bterm1\b and just then \bterm2\b This seems to indicate that I should use an array of patterns instead of a single pattern with lookaheads... is this right? it seems wrong... Here is an example test code and resulting times: public static void speedLookAhead() { Matcher m, m1, m2; boolean find; int its = 1000000; // create long non-matching string char[] str = new char[2000]; for (int i = 0; i < str.length; i++) { str[i] = 'x'; } String test = str.toString(); // First method: use one expression with lookaheads m = Pattern.compile("(?=.*\\bterm1\\b)(?=.*\\bterm2\\b)").matcher(test); long time = System.currentTimeMillis(); ; for (int i = 0; i < its; i++) { m.reset(test); find = m.find(); } time = System.currentTimeMillis() - time; System.out.println(time); // Second method: use two expressions and AND the results m1 = Pattern.compile("\\bterm1\\b").matcher(test); m2 = Pattern.compile("\\bterm2\\b").matcher(test); time = System.currentTimeMillis(); ; for (int i = 0; i < its; i++) { m1.reset(test); m2.reset(test); find = m1.find() && m2.find(); } time = System.currentTimeMillis() - time; System.out.println(time); } This outputs in my computer: 1754 150

  • Redirect to Apache default 404 page with mod_rewrite?

    - by Pekka
    Is there a way to actively serve Apache's default 404 page for a number of URLs using mod_rewrite? Not a custom error document, but a rule like RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule -- serve 404 page ----- I guess I could build a PHP page that sends the 404 header and have mod_rewrite redirect all the URLs there but I would prefer a solution that is based on mod_rewrite only. I just had the idea of redirecting to a non-existent address: RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule .* /sflkadsölfkasdfölkasdflökasdf but that would give the user the message "/sflkadsölfkasdfölkasdflökasdf does not exist" on the error page, which looks a bit unprofessional.

  • C++ STL Map vs Vector speed

    - by sub
    In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.). At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted. Then I though using a map, in my case map<string,symbol>, would be better than iterating through the vector all the time but: It's a bit hard to explain this part but I'll try. If a variable is retrieved the first time in a program in my language, of course its position in the symbol table has to be found (using vector now). If I would iterate through the vector every time the line gets executed (think of a loop), it would be terribly slow (as it currently is, nearly as slow as microsoft's batch). So I could use a map to retrieve the variable: SymbolTable[ myVar.Name ] But think of the following: If the variable, still using vector, is found the first time, I can store its exact integer position in the vector with it. That means: The next time it is needed, my interpreter knows that it has been "cached" and doesn't search the symbol table for it but does something like SymbolTable.at( myVar.CachedPosition ). Now my (rather hard?) question: Should I use a vector for the symbol table together with caching the position of the variable in the vector? Should I rather use a map? Why? How fast is the [] operator? Should I use something completely different?

  • Open page in Joomla

    - by dutt
    I'm using Jumi to echo php code and then showing that in a Joomla Article, and everythings working fine. Now I want to do this: The output is basically a list from a database like this: Name Price Type A 1 T1 B 2 T2 In this list I want to include links to only show items of the same type, so "T1" would like to a page only showing things of type T1. So I thought I would do this by making a new page that takes a type and then get all the items of that type from the database. Without Joomla this wouldv'e been a piece of cake, with Joomla I'm not quite sure where to begin. How should the a href=... tags in the html code printed by my php script look? Is my basic structure still correct, and if so, how do I make Joomla open the new page in the normal frame and not replace the whole Joomla page. some kind of target-frame attribute?

  • speed up calling lot of entities, and getting unique values, google app engine python

    - by user291071
    OK this is a 2 part question, I've seen and searched for several methods to get a list of unique values for a class and haven't been practically happy with any method so far. So anyone have a simple example code of getting unique values for instance for this code. Here is my super slow example. class LinkRating2(db.Model): user = db.StringProperty() link = db.StringProperty() rating2 = db.FloatProperty() def uniqueLinkGet(tabl): start = time.time() dic = {} query = tabl.all() for obj in query: dic[obj.link]=1 end = time.time() print end-start return dic My second question is calling for instance an iterator instead of fetch slower? Is there a faster method to do this code below? Especially if the number of elements called be larger than 1000? query = LinkRating2.all() link1 = 'some random string' a = query.filter('link = ', link1) adic ={} for itema in a: adic[itema.user]=itema.rating2

  • Hiding all panels on a web content form within a master page

    - by Jack Marchetti
    I'm trying to hide all panels on a page, when a button click occurs. This is on a web content form, within a master page. The contentplageholder is named: MainContent So I have: foreach (Control c in Page.Form.FindControl("MainContent").Controls) { if (c is Panel) { c.Visible = false; } } This never find any panels. The panels are within an Update Panel, and I tried foreach(Control c in updatePanel.Controls) { } and this didn't work either. I also tried : foreach(Control c in Page.Controls) { } and that didn't work either. Any idea what I'm missing here?

  • How to get parameters out of an ascx back to the main aspx page

    - by Hallaghan
    I've got an aspx page that renders an ascx page with filtering capabilities. Inside the ascx page, parameters are passed as follows: <tr> <td class="label">Plataforma</td> <td class="field lookup"><%= Html.Lookup("s.Site", null, Url, "Sites") %></td> </tr> <tr> <td class="label">Data</td> <td class="field date"><%= Html.TextBox("s.Date", DateTime.Today.ToString("yyyy-MM-dd")) %></td> </tr> I need to be able to get those parameters on the main aspx page, because they are needed for an action that is called there. How could I access these parameters?

  • Redirecting image to php page.

    - by Searock
    Hi, Is it possible to redirect a user to a php page and then redirect to different image, if the user is requesting for the image ? For example if user requests for the image or if other website requests for the image, it should be redirected to the php page and then redirected to a different image. Like if other website requests for http://example.com/images/a.gif, the website will get a different image i.e. http://example.com/images/b.gif. Is it possible? Let me know if I am not clear with my problem. Thanks. Edit : I am trying to create avatar changer for a forum, but the problem is that I cannot add a php link to my avatar. So I think if I could add a image link and when the forum requests the image I could redirect it internally to a php page and then from the php page I would redirect it to a different image.

  • Drupal - Hide a single page from search index

    - by ilowe
    Hi, I've taken over an existing Drupal installation and have been asked to remove a single page from the site search results. I know about the lullabot tutorial through this question: http://stackoverflow.com/questions/1748837/hide-drupal-nodes-from-search, but that talks about excluding a class of content when I really just want to exclude a single page. I've tried manually deleting the node from the search_index table, but that didn't seem to work either. Any recommendations for excluding a single regular content page from the search index?

  • Getting up to speed on modern architecture

    - by Matt Thrower
    Hi, I don't have any formal qualifications in computer science, rather I taught myself classic ASP back in the days of the dotcom boom and managed to get myself a job and my career developed from there. I was a confident and, I think, pretty good programmer in ASP 3 but as others have observed one of the problems with classic ASP was that it did a very good job of hiding the nitty-gritty of http so you could become quite competent as a programmer on the basis of relatively poor understanding of the technology you were working with. When I changed on to .NET at first I treated it like classic ASP, developing stand-alone applications as individual websites simply because I didn't know any better at the time. I moved jobs at this point and spent the next several years working on a single site whose architecture relied heavily on custom objects: in other words I gained a lot of experience working with .NET as a middle-tier development tool using a quite old-fashioned approach to OO design along the lines of the classic "car" class example that's so often used to teach OO. Breaking down programs into blocks of functionality and basing your classes and methods around that. Although we worked under an Agile approach to manage the work the whole setup was classic client/server stuff. That suited me and I gradually got to grips with .NET and started using it far more in the manner that it should be, and I began to see the power inherent in the technology and precisely why it was so much better than good old ASP 3. In my latest job I have found myself suddenly dropped in at the deep end with two quite young, skilled and very cutting-edge programmers. They've built a site architecture which is modelling along a lot of stuff which is new to me and which, in truth I'm having a lot of trouble understanding. The application is built on a cloud computing model with multi-tenancy and the architecture is all loosely coupled using a lot of interfaces, factories and the like. They use nHibernate a lot too. Shortly after I joined, both these guys left and I'm now supposedly the senior developer on a system whose technology and architecture I don't really understand and I have no-one to ask questions of. Except you, the internet. Frankly I feel like I've been pitched in at the deep end and I'm sinking. I'm not sure if this is because I lack the educational background to understand this stuff, if I'm simply not mathematically minded enough for modern computing (my maths was never great - my approach to design is often to simply debug until it works, then refactor until it looks neat), or whether I've simply been presented with too much of too radical a nature at once. But the only way to find out which it is is to try and learn it. So can anyone suggest some good places to start? Good books, tutorials or blogs? I've found a lot of internet material simply presupposes a level of understanding that I just don't have. Your advice is much appreciated. Help a middle-aged, stuck in the mud developer get enthusastic again! Please!

  • Login to website and use cookie to get source for another page

    - by Stu
    I am trying to login to the TV Rage website and get the source code of the My Shows page. I am successfully logging in (I have checked the response from my post request) but then when I try to perform a get request on the My Shows page, I am re-directed to the login page. This is the code I am using to login: private string LoginToTvRage() { string loginUrl = "http://www.tvrage.com/login.php"; string formParams = string.Format("login_name={0}&login_pass={1}", "xxx", "xxxx"); string cookieHeader; WebRequest req = WebRequest.Create(loginUrl); req.ContentType = "application/x-www-form-urlencoded"; req.Method = "POST"; byte[] bytes = Encoding.ASCII.GetBytes(formParams); req.ContentLength = bytes.Length; using (Stream os = req.GetRequestStream()) { os.Write(bytes, 0, bytes.Length); } WebResponse resp = req.GetResponse(); cookieHeader = resp.Headers["Set-cookie"]; String responseStream; using (StreamReader sr = new StreamReader(resp.GetResponseStream())) { responseStream = sr.ReadToEnd(); } return cookieHeader; } I then pass the cookieHeader into this method which should be getting the source of the My Shows page: private string GetSourceForMyShowsPage(string cookieHeader) { string pageSource; string getUrl = "http://www.tvrage.com/mytvrage.php?page=myshows"; WebRequest getRequest = WebRequest.Create(getUrl); getRequest.Headers.Add("Cookie", cookieHeader); WebResponse getResponse = getRequest.GetResponse(); using (StreamReader sr = new StreamReader(getResponse.GetResponseStream())) { pageSource = sr.ReadToEnd(); } return pageSource; } I have been using this previous question as a guide but I'm at a loss as to why my code isn't working.
