I'm working on the Cruise Booking app using strokes / tiles which multiple Uses the servlet / jsp to display the right jsp for further performance. But, once you are used to present the page, after reaching the final JSP, call $ {pageContext.request.requestURL} in the JSP it Returns the path of JSP For example Original request: forwarded to / booking / getCruiseDetails Is done: / booking / validateCruiseDeteails.jsp is forwarded to: / booking / validate user. JSP Finally it is forwarded: / Booking / Show Cruises Jsp Then, when I call on $ {pageContext.request.requestURL} / bookmark / showcruiseDetails.jsp me / booking / ShowCruiseDetails.jsp How can you get the original (client created) request URL from JSP that has reached through multiple forward I got the following post on stack overflow Used to indicate that solution, but they do not know how to find the original request URL after a number of requests. You can use a filter to request the a...

यदि unary + / - ऑपरेटर्स को रूपांतरण के रूप में प्रयोग किया जाता है संख्या () कास्टिंग फ़ंक्शन, तो हमें एकरी ऑपरेटरों की आवश्यकता क्यों है? इन unary ऑपरेटरों की विशेष आवश्यकता क्या है? यूनरी + ऑपरेटर नंबर ऑपरेटर को अपने ऑपरैंड को परिवर्तित करता है। यूनरी - ऑपरेटर नंबर ऑपरेटर को अपने ऑपरेंड को रूपांतरित करता है, और फिर इसे नकार देता है (प्रति) व्यवहार में, यूनरी - को सामान्य अभिव्यक्तियों में केवल नकारात्मक संख्या डालकर उपयोग किया जाता है, उदाहरण: var x = y * -2.0; यह काम पर एक कम मासिक ऑपरेटर है यूनरी + नंबर () कन्स्ट्रक्टर के समतुल्य है, जिसे फ़ंक्शन के रूप में बुलाया जाता है, जैसा कि नमूना द्वारा निहित है। मैं केवल इतिहास पर अनुमान लगा सकता हूं, लेकिन unary +/- ऑपरेटर कई सी-व्युत्पन्न भाषाओं में इसी तरह व्यवहार करते हैं। मुझे संदेह है कि संख्या () व्यवहार यहां भाषा के अलावा है।

I'm a little confused. I have a simple controller that loads a view. There is a form in the view and links to some CSS files. I really do not want to do ../../ css / global.css in my link tag. I want to use the base_url () method and then go / css / I know that a friend uses the following: & lt; Link href = "{base_url} css / style.css" rel = "stylesheet" type = "text / css" /> However, I can not get it to work, that uses CodeIgniter 1.7, however, I am using the latest (2.something) version. I'm new to CodeIgniter and I was roaming with it, but I can not even add a simple CSS file: ( My view is in /logic/views/index.php , my CSS files / css / . I think your problem is that base_url is a function in ci 2+, so try it instead link href =" & lt; ? Php echo base_url ()? & Gt; css / style.css "rel =" stylesheet "type =" text / css "/> How do you define base_url If you had other...

I know that I can get all the checkboxes on the page on this checkbox: $ ('Input [type = checkbox]'). Each (function () {var sThisVal = (this.checked? $ (This) .val (): "");}); But now I'm using it on a page that has some other checkboxes I do not want to include. How can I change the checked-up check box only to the above code on which there is a certain category on them? $ ('theClass: checkbox: check') To class theClass .

What's wrong with the code snippet below that VS2010 will not compile it? int m = sqrt (n); (I am trying to ensure that there is a prime prime ...) You have to pass a specific floating point type on sqrt - there is no integer overload. Use eg: long double mi = sqrt (static_cast & lt; long double & gt; (n)); As you include cmath not math.h , I'm assuming that you want C ++ For C, you will need to use eg: double M = sqrt ((double) n); You just error means that the compiler can not automatically select a sqrt function for you - you converted the integer passed to a floating point type And the compiler does not know which floating point type and the sqrt function should be selected.

I have a gridview with five bound fields. When inserting values ​​into the grid, I get the textbox field in the cells and it is working fine.

Actually I want something like github headers and footers, different color from headers and footer body and Both go for forever My center (main) lamp is fixed width, so that means I need a container divis. I have something like this: I would like to align headers, footers and containers, but if the container was only a fixed width, then it would be aligned without aligning it Is hard for The background and main body for the headline I thought was different, but the footer looks different, but it looks like a dirty hack and it seems like it does not make sense. Is this structure adequate semantic? Container header main-content footer Or I should be living with my original plan Container header main Content Footer Edit I think the StackHowarflow actually uses the Gitb style where the headers with fodder are separated from the container. And main content. Is this the normal way to do this layout? (Please provide some articles / links that support it) You d...

When I launch a Winform application from Visual Studio, additional runtime checks are checked to check for errors It throws an exception from if I use a form element outside the thread that it was created, then the text "cross-thread operation is not valid". When I run my integration test, which initiates the process outside of Visual Studio, this check is not enabled. I'm running the executable build result, besides launching it with the process.

Is there any way to generate a unique ID in postgres? Suppose I have two files: File 1: a, b, c, d, e, f file2: h, i, j a, f, h and I want to include them in the same table (which should be possible because they have the same data type elements) but still able to obtain them, Separately later, can I get postgrescale for generating a unique ID for me? You can definitely do it! You can create a loaded_files table and you can store the name of the file you are loading ID from loaded_files and Insert that data into your file_items table. What you are asking is a solution that is usually solved during data loading in the application code or with other SQL statements.

@ orders.closed_today is an array of all orders closed for today. How can I get all the items for this? i.e. @Itms = @order.closed_tayday.itms update reports html & lt; % @items = Item.in_orders (@ Orders.closed_today)%> item model scope: in_orders, lambda {| Order | Where ('in order_id (?)', Orders.map (& id) .join (','))} Simple: Map items. @items = @order.closed_tod.l (: include = & gt;: item) .map (& amp;; item) This will give you: = & gt; [[Item 1, Item 2], [Item 2, Item 3]] To get exclusive items: @order.close_toded. L (: included =>: items) .map (and: items). Flaten.Yinek It is not a permanent way of bringing related items; N + 1 Performance Problems Be Careful More generally, you should do something like this: area of ​​square item: closed_tode, joins (: order) & amp; And just call: Item.closed_today

I created an app that changes the OSX garbage icon. However after this icon. Png files have been replaced ... / CoreServices / Dock.app / resources will not show new icons before this trash changed state (fx empty -> full or full -> empty). . I have tried to see the change using the killer dock, the killer finder, but it is not working .. I have a library / cash / com. I've read about removing the doc cache file in Adling Dock ... but I do not think to find this file? Can you help me? I find the by using the bass command that was actually finished -name com.apple.dock .iconcache . Then I removed all the matches, it works perfectly!

I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

I have a small problem with the rabbit that I do not understand.

I have not heard anything about RTOS, but they give the programmer more control over the scheduler so that the priority is inversely Avoid, their time is more consistent, better multitasking but all standard desktop setup uses OS which are not real time. There should be some tradeoffs for using RTOS, what are they? RTOS typically features general definition of "real-time" people for business performance and forecasting and traceability "Deterministic"; You can not make a fate without paying for it. In the general purpose OS, we are inspired by "common-case" behaviors - we really want very good performance and much more flexibility. At RTOs, we want a reliable roof over the "worst condition" behavior, and we pay in throughput or normal-type behavior (often referred to as). Yes, it is possible to make hybrids, such as Windows or Linux real-time threads but somewhere you are usually finishing because only a limited set of available resour...

My problem is just that. I have tried to declare the string as a specific shape, I sort and do everything, but the only thing that works is putting the string in the main method in the main method that I use I am This is disappointing, because I have tried all those things which I can think of. When I import them from another class, then why do the elements become zero? I added a main method for the trick class and also moved it there to do it, but there is no benefit.

I need to create a calendar function in an HTML function. I'm looking for some ways to capture a snippet of some code like a Google calendar to put in a division on my website. The goal is that my client can manage their own calendars. I am a professional SEO who glows as a web designer. I am quite normal with HTML and CSS, but it's about - I usually create small sites with static content. If I can catch a Facebook or Twitter feed, then I think I should be able to do this with the calendar function. Do you see the calendar implemented in JavaScript? If so, you can put directly in the page Another good option is , but there is dependency on its jQuery JavaScript library.

I am creating a webpage that will retrieve some form data from several other pages. For example, hidden Form Field: & lt; Input type = "hidden" id = "thefield" value = "thegoods" /> Now there is always one ID in this area, but sometimes written with double quotes ("), sometimes a single (') and sometimes none. Therefore, it is difficult to do just that, to recover the necessary information, an "index". Do not in any way return the value of form elements in C # .net in a jquery way Unwin Any help appreciated . Example: The easiest way is probably using. code> HtmlAgilityPack.

I was wondering if it is possible to enter a binary number and translate them back into text. For example, 01101000 01100101 01101100 01101100 01101111 "and will make it secret in the word" hello ". Just a few logical corrections: Here are three steps Change the binary set to an integer then the integer in a character then insert the string you are creating Fortunately a radix takes for the parseInt basis. Therefore, once you cut an array of substrings necessary to reach string up (perhaps) length 8, or , then you only need to do this (char) Integer .parseInt (S, 2) and concatenate. string s2 = ""; For the next four (int i = 0; i & lt; = s.length () - 8; i + = 9) // It is a bit tricky that we want [0, 7], [9, 16] e.t.c. (If the bytes are delimited by increment index 9) {nextChar = (char) Integer.parseInt (s.sstring (i, i + 8), 2); S2 + = nextChar; }

I have created a 2D grid in Java, where each cell can have a certain attribute, the color is called . At every frequency of the main loop, that color may possibly change What I want to be able to do is: - When zoomed in, this small subset of the grid and the grid of each grid Will show the actual color. - As you zoom out and look at more cells at a time, seeing the cells individually will start to become very small, so I will be able to use that area (a collection of single cells) as a color I want to be able to present (say that one of the most frequent occurrences in that collection) I thought to do that one thing would be to use hierarchical tree / pyramid structure, Where on the leaves you have each room. Each parent is given information of each child in its node, so to draw a map at a high zoom level, instead of seeing each room individually, only a few levels will go down, however, changing the parents from the leaves And later, the changes occurring at every high level...

I need to combine a string with a list of strings so that I can use it as a dictionary key Can I This list will be small (typically 1, but sometimes 2 or 3 items). What is the fastest way to do this? ago: my_string == "foo" my_list == ["bar", "falcon", "quax", "etc."] After: my_tuple == ("foo", "bar", "baz", "qux", "etc") (Note: my_list should not change itself). I can not talk for performance, but this is definitely the simplest, I can think I: my_tuple = tuple ([my_string] + my_list)

What cache money mani eliminates the requirement of DB level indexes (usually used to improve query retrieval is done)? caching = Your query is obtained from the query cache (RAM) if they are Indexing = With the help of the database, a few questions (very) have been answered fast (a simplified definition, but enough here for my purpose). Therefore, the speed of questions increases without having to kill the database in the cache, whereas the data going through the cache in the index is accelerated and the database is pressed. The benefit you get from caching depends on the specifications of your application. If most questions ask for the same data, or you have fewer updates than read, then using the caching layer should prove to be a good idea. However, I have seen that even in the best scenarios, 15-20% of questions still reach the database. This means that you can not trust caching alone. But most importantly - the database index is simple to define and usually requi...

Thanks in advance for any feedback I am facing a trivial problem. Hardware: Motorola (Android Phone) I'm displaying in an image view. The image itself has been caught through the ContentResolver. The problem is that whenever I tilt my mobile, the image is empty, by logging out the logs and variables, I came to know that the relevant URI is back to its default (i.e. zero ) Goes back to the value whenever I bend the mobile. Of course there is an alternative solution for this. Using stable variables. But I am wondering if there is another solution because I really want to work around the URI, whatever I want to do with my actions. Do anyone know what's going on? Regards. Your activity automatically restarts, whenever orientation changes between the picture and the landscape Look for ways to handle it.

This new feature is really convenient. Recently I have "Microsoft serv-in" - a code framework ", and it has been mentioned that" optional parameter "is not CLS-compliant.

I started playing with Sinatra and deployed on Heroes, which I find really enjoyable. I do not need Scalability to provide Heroku, but I really like the ability to deploy an app with their CLI and a simple push. Is there an open source project that releases a VM image which I can slap, I say on an EC2 example and that's the same service (web server, postgraze, GIT push-to-deployment, maintenance mode ... ) Will provide 'small'? Check out they are releasing their platform as open source.

I'm going to submit my app, it plays some radio streams. And displays some information from my web server 1) It performs an investigation when the app starts for accessibility and informs the user that no connection is available. Do I need to do more here, as if the user is trying to play the radio even when there is no connection, continues to pop up the alerts? Or once the app starts enough? Maybe I check on every button pressed button which tries to play a radio station or who tries to download some data from the web server? When the app starts but is lost later, then is web connectivity? 2) The app can run the radio stream in the background Is there something special about this that I expect to handle? If the app is interrupted by the phone call, do I expect the auto radio to resume after the call or is it OK to leave the user? It's okay to control the volume control volume on the edge of the phone. I have not added any other button in the app to the phone. Is this ...

Is there a way to reference the clause instead of triggering the update? ** More information ** I am trying to get this issue:. This amazing product will try to update those rows that have changed or who are not present. Since I do not need any care about existing data / if I can modify it that due to being more normal the update will be going on and I can move forward. The well-deleted table shows the data that you selected with the clause, so if You know where the pen is at 1, then you know the values ​​you ask? But know exactly where it is, no one. The only data available in the trigger is data in the table before and after the update statement. It may be that if you have expressed that it is easy to help you, then the intrigue you want to trigger is easy.

Normally i __ package __-> Meta-> I can finalize a class in the compilation through the make_imurable end of class. However, when I make an orbit unchanged, which plays a role on the runtime? Should I do the same to get better performance or is it incompatible with make_immutable ? make_immutable starts accelerating the acceleration of the object, but does this once when the object is installed? For example, something on the lines of this: build {my $ self = shift; Module :: Load Use; ### Use the passed logic to determine the roles applied to this example ### of objects. Load and apply roles {$ load for $ my role ($ self-> _determine_roles ()); $ Role- & gt; Meta & gt; Applicable ($ self); } ### $ Self now a class :: Mop :: class :: __ ANON __... anonymous class ### Should I say then that I want to change it with something like this?

Message Sentence (); . SoapMessage.getSOAPBody () addChildElement (cdataElem); I can not find a way to do this properly and I'm sure it should be simple ... can anyone help? Thanks I had a similar problem. Finally I found a solution using the decoration: SOAPMessage message = factory.createMessage (); . Message.getSOAPBody () addChildElement (message.getSOAPpart () createCDATASection (xmlDocAsString).); Apparently SOAPPart acts as a DOM doctor.

I have searched for this topic but can not find the posts I have experienced that I really do I am here. I have a visual studio solution that I need to work on, it is quite large and has 16 projects. Everything is so slow and choppy (except for the introduction which is really fast). On clicking a line in the text editor, the cursor takes approximately 5 seconds to move. Switching between files ~ 1-2 mins (if I'm lucky) Clicking on 'Tools' for the drop down menu to display ~ 2 minutes . If I click on one of the projects correctly, drop down menu 5-10 minutes before. During this time my whole PC is locked. Video studio off (in anger) ~ 10-20 amin For debugging and building ... Well I have never managed to get it far away. Task Manager (it takes a long time to open with explorer Visual Studio) is seeing that there is not much memory / CPU consumption.

Motorola XOOM has an SD card slot from what I've read, but currently slot is disabled in shipping devices. Developing apps that store data on SD card, whose path is (as 2.2) / mnt / sdcard / . What does getExternalStorageDirectory () come back to XOOM? Will this change occur if the SD card is enabled? What is the External Directory () on XOOM? Indeed, it returns / mnt / sdcard . However, it indicates some on-board storage, like many other Android devices. My guess is that they have chosen / mnt / sdcard for greater compatibility with developers, which are valuable in their apps. Will this change occur if the SD card is enabled? You are asking better than that question.

I am trying to get a list of User IDs (UIDs) that have posted more than 3 articles. Here's my SQL: Select COUNT from n.uid by node group (n.type = 'article') & gt; 3 After reading something, I am guessing my mistake that I am with the use of COUNT, but I do not know what I am doing wrong. Any sign? Thanks Stack! more like ... SEID UID FROM node WHERE Type = 'Articles' Group by UID Hoving COUNT (UID) & gt; 3 Edit : I WHERE vs. I'll add a bit more information on HAVING . As far as I can remember, the use of hoisting is done to implement the group BY conditions after the aggregation. WHERE is usually used to apply the conditions in the table.

I want a method that takes an object as a parameter, and adds it to a simple list later , I want to call a method on this object, but the time of the hole, I do not want to define the object as a specific type, just type the object I know that the object in the object that I want to call I'm sure because of this To do that I pass the object with only that method. Something like this: Public Zero addElement (object obj) {elementlist.add (obj); }. . Elementlist.get (i) .SomeMethodIknowItHas (); However, it is not working, is there any way that I can force him to call that method? If you do not really want to insert the object as a specific type, you can use the reflection Have to do. However, this is generally considered bad behavior, and you should see if there is any way you can use that instead of generic with interface or base class. The fact is that you know that this kind of method is that it should implement an interface that tells the compiler that there ...

I have a Perl script that processes millions of performance data, so I need to store metric information efficiently. I searched the function of Pearl, which allows you to manipulate the bits of the string directly, it can be used to simulate a array memory efficiently. And it works very well to store integer values. But for floating point values, it does not work very well. Here's an example: #! / Usr / bin / perl my ($ s) = ''; Vec ($ s, 0, 32) = 1234; Vec ($ s, 1, 32) = 12.34; Vec ($ s, 2, 32) = pack ('f', 12.34); Print "First vec:". Vec ($ s, 0, 32) "(must be '1234') \ n"; Print "2 VCC:" Vec ($ s, 1, 32) "('12 .34 ') \ n"; Print "3 vc:" unpack ('f', vce ($ s, 2, 32)) "(must be '.34') \ n"; To run this code, on my machine (Mac OS X 10.6.7, Pearl 5.8.9) gives the following: First vec : 1234 (must be '1234') second vec: 12 ('12 .34 ') 3 VC: (must ...
