  • jQuery selector loads images from server

    - by Guillaume
    Hi! here is the code: <script type="text/javascript"> var ajax_data = '<ul id="b-cmu-rgt-list-videos"><li><a href="{video.url}" '+ 'title="{video.title.strip}"><img src="{video.image}" '+ 'alt="{video.title.strip}" /><span>{video.title}</span></a></li></ul>'; var my_img = $(ajax_data).find('img'); </script>` ajax_data is data from a JS template engine where I need to get some part of it. The problem is that jQuery does a GET on the img src={video.image}: GET /test/%7Bvideo.image%7D HTTP/1.1 (on Firefox Live HTTP headers). This GET generates a 404 from the server. Any clues on how to solve this? Thanks a lot :)

  • How do I write escape characters verbatim (without escaping) using StreamWriter?

    - by Joel
    I'm writing a utility that takes in a .resx file and creates a javascript object containing properties for all the name/value pairs in the .resx file. This is all well and good, until one of the values in the .resx is This dealer accepts electronic orders. /r/nClick to order {0} from this dealer. I'm adding the name/value pairs to the js object like this: streamWriter.Write(string.Format("\n{0} : \"{1}\"", kvp.Key, kvp.Value)); When kvp.Value = "This dealer accepts electronic orders./r/nClick to order {0} from this dealer." This causes StreamWriter.Write() to actually place a newline in between 'orders.' and 'Click', which naturally screws up my javascript output. I've tried different things with @ and without using string.Format, but I've had no luck. Any suggestions? Edit: This application is run during build to get some javascript files deployed later, so at no point is it accessible to / run by anyone but the app developers. So while I obviously need a way to escape characters here, XSS as such is not really a concern.

  • Does an HttpHandler require an aspnet_isapi.dll mapping

    - by DEH
    Hi, If I configure (via web.config) an httphandler to handle all .gif requests for a specific folder, is it absolutely essential for me to map .gif requests to aspnet_isapi.dll in IIS? Is there any other way of ensuring that the .gif http request will be handled by aspnet_isapi.dll? I have a server configured where the virtual dir that contained the .gif-aspnet_isapi.dll mapping has been deleted, but the .gif requests are still being passed to the handler. Anyone know how this might be being done, and where the setting might be lurking? Thanks

  • Call center workflow scenario with WF 4

    - by mossy
    I need to develop a workflow for a call center. A bot will ask some predefined questions to the caller. Based on the answers the workflow will decide the questions to ask and finally redirect the caller to a representative that has required skills. Based on the scenario above, I have several questions. How can I make the workflow "wait" between asking a question to the caller and receiving response from the caller? Do I have to use HandleExternalEvent? If so do I have to define an event for every question? Flowchart workflow seems to be the best solution but I can't imagine how to handle this waiting issue right now. Any help is appreciated.

  • PHP: prepared statement, IF statement help needed

    - by JGreig
    I have the following code: $sql = "SELECT name, address, city FROM tableA, tableB WHERE tableA.id = tableB.id"; if (isset($price) ) { $sql = $sql . ' AND price = :price '; } if (isset($sqft) ) { $sql = $sql . ' AND sqft >= :sqft '; } if (isset($bedrooms) ) { $sql = $sql . ' AND bedrooms >= :bedrooms '; } $stmt = $dbh->prepare($sql); if (isset($price) ) { $stmt->bindParam(':price', $price); } if (isset($sqft) ) { $stmt->bindParam(':price', $price); } if (isset($bedrooms) ) { $stmt->bindParam(':bedrooms', $bedrooms); } $stmt->execute(); $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC); What I notice is the redundant multiple IF statements I have. Question: is there any way to clean up my code so that I don't have these multiple IF statements for prepared statements?

  • MySQL performance

    - by kapil.israni
    Hi, I have this LAMP application with about 900k rows in MySQL and I am having some performance issues. Background - Apart from the LAMP stack , there's also a Java process (multi-threaded) that runs in its own JVM. So together with LAMP & java, they form the complete solution. The java process is responsible for inserts/updates and few selects as well. These inserts/updates are usually in bulk/batch, anywhere between 5-150 rows. The PHP front-end code only does SELECT's. Issue - the PHP/SELECT queries become very slow when the java process is running. When the java process is stopped, SELECT's perform alright. I mean the performance difference is huge. When the java process is running, any action performed on the php front-end results in 80% and more CPU usage for mysqld process. Any help would be appreciated. MySQL is running with default parameters & settings. Software stack - Apache - 2.2.x MySQL -5.1.37-1ubuntu5 PHP - 5.2.10 Java - 1.6.0_15 OS - Ubuntu 9.10 (karmic)

  • UIWebView is ignoring cookies?!

    - by A. Miladinovic
    Hello everybody, I am creating an app for the iPhone that fetches a specific page from a website, but to be able to view this site you need to log in with a username and a password. I've created this code: NSString *urlAddress = @"http://www.wdg-hamburg.de"; NSURL *url = [NSURL URLWithString:urlAddress]; NSString *post = @"name=loginname&pass=pass&form_id=user_login&op=Anmelden"; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod: @"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; [vPlan loadRequest:request]; But I am not logged in at the UIWebView! I am logging NSHTTPCookieStorage to the console and it shows me the necessary cookie, but I dont get logged in. Does anybody knows how I can fix that? Kind regards, A. Miladinovic

  • ADO.NET parameters from TextBox

    - by Geo Ego
    I'm trying to call a parameterized stored procedure from SQL Server 2005 in my C# Winforms app. I add the parameters from TextBoxeslike so (there are 88 of them): cmd.Parameters.Add("@CustomerName", SqlDbType.VarChar, 100).Value = CustomerName.Text; I get the following exception: "System.InvalidCastException: Failed to convert parameter value from a TextBox to a String. ---> System.InvalidCastException: Object must implement IConvertible." The line throwing the error is when I call the query: cmd.ExecuteNonQuery(); I also tried using the .ToString() method on the TextBoxes, which seemed pointless anyway, and threw the same error. Am I passing the parameters incorrectly?

  • OWA (Outlook Web Access) won't give user a link to attached document. Gives "Open as Web Page"

    - by Jerry Mayers
    I have been testing OWA and have found that when there is an attached file on a message it shows the "Attachments:" then the file name (but no link) and then [Open as Web Page] link. The user has to click on that which opens a new window and previews the document, then the user gets "You are currently viewing:" followed by the file name. This time the file name is a link that they can open/download. This happens for Office documents and PDF file at least. How do I make it so users can get a direct link to the file on the original message window?

  • Why am I losing cached network passwords after a restart of Vista?

    - by Nauman
    The passwords cached for Network shares on other computers and applications like MSN Live, MS Outlook, Sharepoint portal, Outlook Webmail, etc are lost when I reboot my computer, which runs on Vista. I always check the Remember password checkbox in applications/login dialogs where ever prompted. I cannot imagine of a third party program that may clean up this on system restart/shutdown. Any idea, as to what is going wrong?

  • Cannot open files in Visual Studio but in Delphi and Notepad

    - by Andrew J. Brehm
    About an hour ago Visual Studio 2008 decided that it cannot find files any more. This is on 64 bit Windows Vista. When I right-click on a text file (source code or otherwise) and select "open with" and "Visual Studio 2008", I get the following error (example): Windows cannot find 'C:\Users\ajbrehm\Documents\Visual Studio 2008\Projects\Hello Prism\Hello Prism\Main.pas'. Make sure you typed the name correctly, and then try again. When I right-click the same file and select "open with" and "Delphi 2010" or "Notepad" (both other options available for text files on my system), the file opens correctly. Oddly enough when the file is part of a Visual Studio project and I open the project itself with Visual Studio (this works), I can open the file from within Visual Studio. Any ideas what might be going on? This started about an hour after I made a complete backup of my Vista VM and after I installed IIS 7, SQL Express, and Sourcegear Vault. The first files I noticed couldn't be opened in Visual Studio any more where Pascal source files in checked-outed folders from Vault. And Vault also seems to be unable to see one of the sources files and claims they don't exist. I found out about Visual Studio not opening ANY files any more when I tried to recreate the file Vault refused to see. Update: I just checked. Another user, "administrator", can still open text files with Visual Studio 2008. Both users have administrator rights. Update: I just restored the hours-old backup. Same problem. Apparently whatever triggered this happened before the install of IIS 7 and SQL Express. Never noticed it before.

  • Can I use an opened gzip file with Popen in Python?

    - by eric.frederich
    I have a little command line tool that reads from stdin. On the command line I would run either... ./foo < bar or ... cat bar | ./foo With a gziped file I can run zcat bar.gz | ./foo in Python I can do ... Popen(["./foo", ], stdin=open('bar'), stdout=PIPE, stderr=PIPE) but I can't do import gzip Popen(["./foo", ], stdin=gzip.open('bar'), stdout=PIPE, stderr=PIPE) I wind up having to run p0 = Popen(["zcat", "bar"], stdout=PIPE, stderr=PIPE) Popen(["./foo", ], stdin=p0.stdout, stdout=PIPE, stderr=PIPE) Am I doing something wrong? Why can't I use gzip.open('bar') as an stdin arg to Popen?

  • How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

    - by Pat
    I have a friend who wishes to work as a freelance web developer, but insists that tables are the way forwards for layouts. Several points he maintains in favour of tables: 1 This is what was taught at the beginning of 10 years of programming & computer science degrees. 2 Large companies use tables to achieve 'technical' things. 3 It saves time I have coded him some examples of CSS exactly matching table based layouts, and provided many links to articles explaining SEO and accessibility benefits. From the perspective of a client, I have been explaining to him that I wouldn't hire someone using outdated methods as their main strategy for layout. As he is my friend and I wish him every success, I believe it is important for him to gain the best start when pitching for work. The question again: How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

  • iPhone tethering app source

    - by jamone
    I know there are a few apps that allow a jail broken iPhone to tether over WiFi to a computer so the computer can use the iPhone's 3G. What I want to know is if anyone knows of any open source apps that do this, or partial code to handle the majority of this that I could make in to a minimal app? I don't want to jail break since I do official development, but would like to be able to compile and sideload an app on my personal phone to do this. Even without jail broken privileges an app could use an existing wifi connection (adhoc created by the computer) to share its 3G.

  • RegEx - Time Validation ((h)h:mm)

    - by Josh
    /^\d{1,2}[:][0-5][0-9]$/ is what I have. this limits minutes to 00-59. It does not, however, limit hours to between 0 and 12. For similarity and uniformity I would like to do this with RegEx alone if possible. Further-more I would like the first digit to be optional. i.e. 09:30 accepted as well as 9:30. I played around with ranges, but something out of range is always acceptable.

  • C++: Switching from MSVC to G++: Global Variables

    - by feed the fire
    I recently switched to Linux and wanted to compile my Visual Studio 2010 C++ source code, which uses only the STL, on G++. My Linux machine currently isn't available but I can try to tell you what is going on, first: As I try to compile my project, all global variables I use in main and which perfectly work on MSVC result in myGlobalVar is not defined in this scope errors. My project is built nearly the same as the example below: // myclass.h class myClass { // .... }; extern myClass globalInstance; // myclass.cpp #include "myclass.h" // myClass functions located here myClass globalInstance; // main.cpp #include "myclass.h" int main( ) { // Accessing globalInstance results in an error: Not defined in this scope } What am I doing wrong? Where are the differences between G++ and MSVC in terms of global variables?

I want it to be in the middle not to top.
