  • Javascript parent page redirection from iframe.

    - by Danil
    Hello to all. I need to implement parent page redirection from iframe. I know that it is impossible to do in different domains due to browsers security. However I found that links have target attribute and tried to use it in the following way: <a href="http://google.com" target="_top" id="testParentRedirect">someLink</a> It works fine if I click this link manually, but I couldn't find cross-browser solution to simulate it using javascript. document.getElementById('testParentRedirect').click(); This works fine in IE, however Firefox and Safary don't know click function :). I tried to work with jquery, but for some reason they don't simulate click event for links. (see following post) I couldn't find any appropriate solution on stackoverflow. Maybe someone could help me in it. I will appreciate it. :)

  • Deploying my flex application

    - by Vatsala
    Hi, I am doing some trial testing awith Amazon ec2 boxes, deploying flex apps running on top of restlet powered webservices. I have this problem - Everytime i deploy the app to the cloud, I'm having to hardcode the IP address of the server into the ActionScript/MXML files (http://72.93.48.39:8080/xxx/abc/) and for certain reasons, i am forced to choose a different IP everytime. and i think its really not the right way to deploy the application. I would like to know what other people do in such scenarios? On thinking about it, i thought i could make it pickup values from the HTMLVars of the HTML wrapper. but that again has to be edited everytime again and again. will it be possible to be able to supply these values : server's ip address, server's port number(in case its not 8080 on some machine) at build time? if so can anyone give me a barbones sample build.xml just as an example?

  • How to find what ActiveX control is referred on a web page?

    - by Sly
    I have developed a web application (ASP.NET Web Forms). One of my customer has very restrictive policies. When he accesses the web page, IE shows this message: Your security settings do not allow Web sites to use ActiveX controls installed on your computer. This page may not display correctly. As far as I know, we don't use ActiveX controls on our page. I did a "View Souce" and did not find anything suspect. How can I find what part of my page refers to an ActiveX. The application uses jQuery and a few jQuery plug-ins. Is there a tool/add-in like "Fire Bug" that I can use to list the ActiveX controls referred on a page?

  • What would you use for deployment scripts in Java?

    - by Nadav
    Hi, I'm working on a Java web project that uses Maven to build its artifacts. At the end of the Maven build we have a few jar and war files that we need to deploy onto our development/testing environment. Right now we're using a pretty hefty Ant script that performs several tasks (on both Windows/Linux machines) Starts/Stops services Copies/deletes files Builds some stuff and then executes it Etc Ant does the job well - but the script is quickly getting very large, and to be honest, it feels inadequate for the task at hand. Are there other alternatives? I've heard of gant, but I'm not sure that's the right way to go. Thanks for helping!

  • Are there any e-commerce websites that use NoSQL databases

    - by Saif Bechan
    I have read a lot lately about 'NoSQL' databases such as CouchDB, MongoDB etc. Most of the websites I have seen using this are mainly text based websites such as The New York Times and Source forge. I was wondering if you could apply this to websites where payment is a huge issue. I am thinking of the following issues: How well can you secure the data Do these system provide an easy backup/restore machanism How are transactions handled commit/rollback I have read the following articles that cover some aspects: Can I do transactions and locks in CouchDB? Pros/Cons of document based database vs relational database In these posts the aspect of transactions if covered. However the questions of security and backups is not covered. Can someone shed some light on this subject? And if possible, does anyone know of some e-commerce websites that have successfully implemented the document based database.

  • Trying to make my leaflet map work on internet explorer

    - by user1270657
    I have been tearing my hair out of late trying to get my web map working on internet explorer. It's working flawlessly on every other major browser but none of the content will load in IE. Anyone out there who's good at browser testing that could help out? I know the leaflet javascript api, which I'm using for this project, supports IE in theory. In practice this isn't working out too well... Link to a live version of the web map: https://mywebspace.wisc.edu/axler/SLRE_Deep_Map/index2.html Let me know if there is anything else I could add that would help in deciphering this problem... Thanks!

  • Https in java ends up with strange results

    - by Senne
    I'm trying to illustrate to students how https is used in java. But i have the feeling my example is not really the best out there... The code works well on my windows 7: I start the server, go to https://localhost:8080/somefile.txt and i get asked to trust the certificate, and all goes well. When I try over http (before or after accepting the certificate) I just get a blank page, which is ok for me. BUT when I try the exact same thing on my windows XP: Same thing, all goes well. But then (after accepting the certificate first), I'm also able to get all the the files through http! (if I first try http before https followed by accepting the certificate, I get no answer..) I tried refreshing, hard refreshing a million times but this should not be working, right? Is there something wrong in my code? I'm not sure if I use the right approach to implement https here... package Security; import java.io.*; import java.net.*; import java.util.*; import java.util.concurrent.Executors; import java.security.*; import javax.net.ssl.*; import com.sun.net.httpserver.*; public class HTTPSServer { public static void main(String[] args) throws IOException { InetSocketAddress addr = new InetSocketAddress(8080); HttpsServer server = HttpsServer.create(addr, 0); try { System.out.println("\nInitializing context ...\n"); KeyStore ks = KeyStore.getInstance("JKS"); char[] password = "vwpolo".toCharArray(); ks.load(new FileInputStream("myKeys"), password); KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509"); kmf.init(ks, password); SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(kmf.getKeyManagers(), null, null); // a HTTPS server must have a configurator for the SSL connections. server.setHttpsConfigurator (new HttpsConfigurator(sslContext) { // override configure to change default configuration. public void configure (HttpsParameters params) { try { // get SSL context for this configurator SSLContext c = getSSLContext(); // get the default settings for this SSL context SSLParameters sslparams = c.getDefaultSSLParameters(); // set parameters for the HTTPS connection. params.setNeedClientAuth(true); params.setSSLParameters(sslparams); System.out.println("SSL context created ...\n"); } catch(Exception e2) { System.out.println("Invalid parameter ...\n"); e2.printStackTrace(); } } }); } catch(Exception e1) { e1.printStackTrace(); } server.createContext("/", new MyHandler1()); server.setExecutor(Executors.newCachedThreadPool()); server.start(); System.out.println("Server is listening on port 8080 ...\n"); } } class MyHandler implements HttpHandler { public void handle(HttpExchange exchange) throws IOException { String requestMethod = exchange.getRequestMethod(); if (requestMethod.equalsIgnoreCase("GET")) { Headers responseHeaders = exchange.getResponseHeaders(); responseHeaders.set("Content-Type", "text/plain"); exchange.sendResponseHeaders(200, 0); OutputStream responseBody = exchange.getResponseBody(); String response = "HTTP headers included in your request:\n\n"; responseBody.write(response.getBytes()); Headers requestHeaders = exchange.getRequestHeaders(); Set<String> keySet = requestHeaders.keySet(); Iterator<String> iter = keySet.iterator(); while (iter.hasNext()) { String key = iter.next(); List values = requestHeaders.get(key); response = key + " = " + values.toString() + "\n"; responseBody.write(response.getBytes()); System.out.print(response); } response = "\nHTTP request body: "; responseBody.write(response.getBytes()); InputStream requestBody = exchange.getRequestBody(); byte[] buffer = new byte[256]; if(requestBody.read(buffer) > 0) { responseBody.write(buffer); } else { responseBody.write("empty.".getBytes()); } URI requestURI = exchange.getRequestURI(); String file = requestURI.getPath().substring(1); response = "\n\nFile requested = " + file + "\n\n"; responseBody.write(response.getBytes()); responseBody.flush(); System.out.print(response); Scanner source = new Scanner(new File(file)); String text; while (source.hasNext()) { text = source.nextLine() + "\n"; responseBody.write(text.getBytes()); } source.close(); responseBody.close(); exchange.close(); } } }

  • Visual studio 'View in Browser' shortcut to specific page?

    - by WowtaH
    We are using Visual Studio 2008 and would like to know if there is a way to create a (keyboard or toolbar) shortcut for the 'View in Browser'-command, but with a specific page from a specific (loaded) project. We always start testing/debugging our app from "Somepage.aspx" from "Project-x". I would like to make a shortcut that does 'View in Browser' with this specific page/file, from this specific project. So even if I am currently working on another file in another project (from the same solution) it should still work... Anybody know if this is possible, and if so, how this can be achieved? Thanks!

  • How to keep Hibernate mapping use under control as requirements grow

    - by David Plumpton
    I've worked on a number of Java web apps where persistence is via Hibernate, and we start off with some central class (e.g. an insurance application) without any time being spent considering how to break things up into manageable chunks. Over time as features are added we add more mappings (rates, clients, addresses, etc.) and then amount of time spent saving and loading an insurance object and everything it connects to grows. In particular you get close to a go-live date and performance testing with larger amounts of data in each table is starting to demonstrate that it's all too slow. Obviously there are a number of ways that we could attempt to partition things up, e.g. map only the client classes for the client CRUD screens, etc., which would have been better to get in place earlier rather than trying to work it in at the end of the dev cycle. I'm just wondering if there are recommendations about ways to handle/mitigate this.

  • UNC path to a folder on my local computer

    - by xt_20
    Hi all, What's the UNC path to a folder on my local computer, and how can I access it? I have tried: 1. Security for the folder -- set to Everyone Full Control (for now!) 2. Sharing permissions -- set to Everyone Full Control (for now!) I can see the folder in \, but can't go in ( is not accessible.) Error message: "You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access pernmissions. The network location cannot be reached. For information about network troubleshooting, see Windows Help." My computer is not connected to a network.

  • Notifying when screen is off

    - by Al
    I'm trying to generate a notification which vibrates the phone and plays a sound when the screen is off (cpu turned off). According to the Log messages, the notification is being sent, but the phone doesn't vibrate or play the sound until I turn the screen on again. I tried holding a 2 second temporary wakelock (PowerManager.PARTIAL_WAKE_LOCK), which I thought would be ample time for the notification to be played, but alas, it still doesn't. Any pointers to get the notification to run reliably? I'm testing this on an G1 running Android 1.6. Code I'm using: notif.vibrate = new long[] {100, 1000}; notif.defaults |= Notification.DEFAULT_SOUND; notif.ledARGB = Color.RED; notif.ledOnMS = 1; notif.ledOffMS = 0; notif.flags = Notification.FLAG_SHOW_LIGHTS; notif.flags |= NOTIF_FLAGS; //static var if (!screenOn) { //var which updates when screen turns off/on mWakeLock.acquire(2000); } manager.notify(NOTIF_ID, notif);

  • Spawning and waiting for child processes in Python

    - by Brendan Long
    The relevant part of the code looks like this: pids = [] for size in SIZES: pids.append(os.spawnv(os.P_NOWAIT, RESIZECMD, [RESIZECMD, lotsOfOptions])) # Wait for all spawned imagemagick processes to finish while pids: (pid, status) = os.waitpid(0, 0) if pid: pids.remove(pid) What this should be doing is spawning all of the processes off, then waiting for each process to finish before continuing. What it does is work for the most part but sometimes crash on the next section (when it expects all of these processes to be finished). Is there something wrong with this? Is there a better way of doing it? The environment it has to work on is CentOS with Python 2.4, but I'm testing on Cygwin with Python 2.5, so it could be that it fails on my machine but will work on the Linux one (the Linux machine is very slow and this error is rare, so I haven't been able to get it on there).

  • How to propose Asp.Net Mvc over other technologies to client?

    - by Arnis L.
    How to show benefits of adopting asp.net mvc to client? I mean - we as developers can understand benefits of easier implementation of automated testing, better control over rendered html etc., but what would be strongest motives for client to accept usage of asp.net mvc? Maybe there's some more nice looking examples built with asp.net mvc (excluding stackoverflow) to show? p.s. Please, do not start flame war. In this case - it doesn't matter if asp.net mvc is better than x or vica versa.

  • How to retrieve all errors and messages from a query using ADO

    - by Johan Levin
    When a SQL batch returns more than one message from e.g. print statements, then I can only retrieve the first one using the ADO connection's Errors collection. How do I get the rest of the messages? If I run this script: Option Explicit Dim conn Set conn = CreateObject("ADODB.Connection") conn.Provider = "SQLOLEDB" conn.ConnectionString = "Data Source=(local);Integrated Security=SSPI;Initial Catalog=Master" conn.Open conn.Execute("print 'Foo'" & vbCrLf & "print 'Bar'" & vbCrLf & "raiserror ('xyz', 10, 127)") Dim error For Each error in conn.Errors MsgBox error.Description Next Then I only get "Foo" back, never "Bar" or "xyz". Is there a way to get the remaining messages?

  • Why would GDI+ colours vary based off whether a tooltip is visible?

    - by dlanod
    I'm displaying a bitmap using GDI+. After loading the bitmap from a DLL resource I set the background colour (blue - #0000FF) to transparent using TransparentBlt. On Windows Vista and later this works as expected. However, on a Windows XP system we're testing on this only works when any tooltip (e.g. the "title" property in IE, or Windows Explorer's tooltip shown when hovering the mouse over a file, etc) is displayed. The rest of the time the background colour is still blue. Has anyone encountered this before, or know of a way to stop this occurring and for the blue to be properly made transparent?

  • How to run an .exe application in another computer?

    - by ADAM
    I am working on a C# application in Visual Studio 2013. When I run the .exe file from my computer, the application runs very well and all the features work. When I tried to run the .exe on another computer, the database side doesn't work well and the connection with the database couldn't be opened. The SqlConnection is constructed as follows: SqlConnection cn = new SqlConnection("Data Source=ADAM-PC;Initial Catalog=integrationdatabase;Integrated Security=True" I don't know how to change the data source to make the connection with the database established in another computer. How can I solve this problem?

  • Is it a good idea to work on header files only, just at the start of the project?

    - by m4design
    To explain my point further, I'm a beginner in programming, and I'm working on a small project. Instead of separating the .cpp file from the header file, I'm implementing the code in the header files, and making one .cpp file for testing. I do this to have less files, hence easier navigation. Then later I'll separate the code as it should be. Will this cause any problems? should I continue doing that? Thanks.

  • How can I receive messages over http without MSMQ

    - by pduncan
    I need a reliable messaging framework that runs over http/https (due to client security requirements) and that doesn't use MSMQ (because some clients will use Windows XP Home). The clients only need to be able to receive messages, not send them. We already have a message queue on the server for each user, and the receivers have been getting messages by connecting to an HttpHandler on the server and getting a Stream from WebResponse.GetResponseStream() We keep this stream open, and pull messages off of it using Stream.Read(). This MOSTLY works, but Stream.Read() is a blocking call, and we can't reliably interrupt it. We need to be able to stop and start the receiver without losing messages, but the old stream often hangs around, even after we call Thread.Abort on its thread. Any suggestions?

  • Do we really need a safe release macro?

    - by Ian1971
    Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

  • Is it possible to use Integrated Windows Auth when Server isn't on the domain?

    - by jskentzos
    Our production web servers ARE NOT part of the domain, but we'd like people to be able to log in automatically since they are logged into the domain on their PC. Is there anyway to get the browser (IE7+) to send the appropriate information to the server (IIS6) so I can retrieve the ServerVariables["AUTH_USER"] or ServerVariables["LOGON_USER"]? I presume the answer is no since if I set the security for windows auth to "on" and anonymous access to "off", then the server wouldn't know what do do with any user information for a domain which it has no knowledge of. I just want to know for sure before I give the SSO team a "not possible" answer.

  • Is it possible to expose an API for my own WebSite ... but use oAuth for the api authentication?

  • A simple algorithm for polygon intersection

    - by Elazar Leibovich
    I'm looking for a very simple algorithm for computing the polygon intersection/clipping. That is, given polygons P, Q, I wish to find polygon T which is contained in P and in Q, and I wish T to be maximal among all possible polygons. I don't mind the run time (I have a few very small polygons), I can also afford getting an approximation of the polygons' intersection (that is, a polygon with less points, but which is still contained in the polygons' intersection). But it is really important for me that the algorithm will be simple (cheaper testing) and preferably short (less code). edit: please note, I wish to obtain a polygon which represent the intersection. I don't need only a boolean answer to the question of whether the two polygons intersect.
