  • How to encode and decode chinese characters?

    - by melaos
    I've try googling around but wasn't able to find what charset that this text below belongs to: 具有éœé›»ç”¢ç”Ÿè£ç½®ä¹‹å½±åƒè¼¸å…¥è£ç½® But putting <meta http-equiv="Content-Type" Content="text/html; charset=utf-8"> and keeping that string into a html file i was able to view the chinese character wording properly. which is: ??????????????? So my question is: what tools can i use to detect the character set of those text? And how do i convert/encode/decode them properly in C#? Updates: Added some test code [TestMethod] public void TestMethod1() { string encodedText = "具有éœé›»ç”¢ç”Ÿè£ç½®ä¹‹å½±åƒè¼¸å…¥è£ç½®"; Encoding encoder = new UTF8Encoding(); byte[] postBytes = encoder.GetBytes(encodedText); postBytes = UTF8Encoding.Convert(Encoding.UTF8, Encoding.Unicode, postBytes); string decodedText = Encoding.Unicode.GetString(postBytes); Assert.AreNotEqual(encodedText, decodedText); } thanks

  • Using 50+ 3rd party web services, should I use BizTalk or just C#?

    - by typemismatch
    I'm building a back-end application that needs to fetch data on various schedules from over 50+ 3rd party web services and that number will continue to grow. The data from these services can currently be grouped into 3 types so each response needs to be mapped to 1 of 3 known schemas. Writing custom c# to hit each web service appears to be a management nightmare never mind having all that data mapping in code. The current thinking is build this on top of BizTalk 2009, still a lot of maintenance but at least a well defined platform with mapping/transformation capabilities already. I'm looking for any advise from anyone who might have done this before, does this really buy us anything? I am aware of a lack of polling features in BTS however there are enough work arounds to feel comfortable about the solution. Thanks!

  • When pressing Back/Menu button my app hangs

    - by Pentium10
    I am having a really annoying bug, which yet I don't know how to trace it. I have an activity with 3 tabs, each populated by adapters build by asynctasks. They are displaying well, navigation is fine. I've extended TabActivity. But whenever I hit the Back/Menu/Search button it halts, then after a while the OS displays me this warning: Sorry Activity Contacts (in application MyApp) is not responding. Force close or Wait. How can I trace this problem on the phone?

  • Maintaining traceability up-to-date as project evolves

    - by Catalin Piti?
    During various projects, I needed to make sure that the use case model I developed during the analysis phase is covering the requirements of the project. For that, I was able to have some degree of traceability between requirement statements (uniquely identified) and use cases (also uniquely identified). In some cases, enabling traceability implied some additional effort that I considered (and later proved) to be a good investment. Now, the biggest problem I faced was to maintain this traceability later, when things started to change (as a result of change requests, or as a result of use case changes). Any ideas of best practices for traceability maintenance? (It can apply to other items in the project - e.g. use cases and test cases, or requirements and acceptance test cases) Later edit Tools might help, but they can't detect gaps or errors in traceability. Navigation... maybe, but no warranty that the traceability is up-to-date or correct after applying the changes.

  • Allow a new line anywhere in the regex?

    - by Scott Chamberlain
    I am having a find a replace in a bunch of RTF documents, The basic pattern I need is \{(?:\\\*)?\\field\\fldlock\{\\\*\\fldinst ?MERGEFIELD ?((?:\\.*?)?[\w\[\]]+?)(?:\\.*?)?\}(?:\{\\fldrslt\})?\} However I then found out there could potentialy be a newline before each slash, so it turned in to this. \{(?:\s*\\\*)?\s*\\field\s*\\fldlock\s*\{\s*\\\*\s*\\fldinst\s*MERGEFIELD\s*((?:\\.*?)?[\w\[\]]+?(?:\s*\\.*?)?)?\s*\}(?:\s*\{\s*\\fldrslt\s*\})?\s*\} But then I hit this it fails fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot Is there way have to have it match a new line anywhere in the search too without adding (?:\r?\n)? everywhere? EDIT To clear up confusion on the new lines. I need to keep the newlines in the document, I only want to remove the newlines if they are inside my match, so in the final example I posted it should replace fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot with fees totaling $\protect ENTEROUTSTANDINGVETERINARYFEES\plain\f0\fs24\prot

  • How to stop Excel from firing Worksheet_Change before Workbook_BeforeSave?

    - by Camil Bancioiu
    Update: Issue Resolved A colleague of mine was changing a cell during Workbook_BeforeSave() without disabling events, therefore triggering Worksheet_Change(). Yes, silly, but at least it's our fault, not Excel's I've noticed that whenever I hit Ctrl+S in Excel, the Worksheet_Change() is fired before Workbook_BeforeSave(). Is it possible to supress this behaviour using VBA code, but without supressing all events (i.e. without Application.EnableEvents = false)? This happens regardless of what I'm doing. I've read about someone having a similar issue with ComboBoxes, but I'm not editing ComboBoxes, yet Worksheet_Change() fires always before saving. Any ideas? I'm only trying to figure out how to bypass some code inside Worksheet_Change() when the document is saved, because that code is only supposed to be executed when the user actually changes something, not when the workbook is saved. Saving is by no means changing...

  • ASP.NET GridView throwing error: "Update is disabled for this control".

    - by NTDLS
    I have the absolutely most simple setup imaginable. A single table defined in an Entity model in ASP.net v4, the model is bound directly to a GridView with AutoGenerateEditButton enabled. However, each time I hit edit, then save, the page throws the error “Update is disabled for this control" for which I cannot find a solution. What is causing this error? What can do to resolve it? <% <asp:GridView ID="MenuItemsGrid" runat="server" DataSourceID="gridDataSource" AutoGenerateEditButton="true" AutoGenerateColumns="true"> </asp:GridView> <asp:EntityDataSource ID="gridDataSource" runat="server" ConnectionString="name=dataEntitiesModel" DefaultContainerName="dataEntities" EntitySetName="MenuItems" /> %>

  • How do develop a Java web application without having to deploy all the time

    - by ChrisSmith..zzZZ
    I've set up a simple Eclipse 3.5/Jetty 6.1 web app which returns hello world. It works. This is on Windows and uses the "Jetty Generic Server Adapter". I have auto deployment working so that it deploys after changes periodically. How do I go about setting it up so that if I change any static content it doesn't have to redeploy i.e I can just hit F5 to see the changes straight away. For minor HTML changes it's quite unusable waiting 20-30 seconds for a deployment.

  • HTML not updating?

    - by Tommy
    I have a CGI application written in C. When I POST delete data to the app from the html form, the action is correctly executed on the server but the page does not refresh after the POST. It does flicker, but displays the non-updated page. I then have to hit the browsers refresh to see the correct html page. Is this the web server? Javascript? or just a browser setting? (I am using GoAhead web server, cgi app in C, javascript, html and Fire Fox.) Any help is appreciated.

  • "Send it to a friend" button on a webpage

    - by kender
    Hey, How often do we see stuff like "Send this page to a friend" on a webpages? Well, I see them quite often. My question is, how do you guys see it's effectiveness? If I hit a webpage that's interesting, and I think my friend would enjoy it, I can just copy the URL from my browser bar, paste it into the email and press "Send" button. In my opinion, it's usually faster and less mistake-aware then the button/link like this on the webpage. In addition, I'm not really sure what this website does with the emails I enter there - don't they store it and then sell for $1/100 addresses to spammers? My question is - when you design a website, do you put such links on the pages (it's often seen on sites with some news/articles)? Does it even make sense?

  • jQuery pagination go to page on input value change

    - by JV10
    I'm creating some pagination for my website, and want to use an input-element to navigate between pages. Like the following example: The input would require the "return" key to be hit for the script to trigger. If the value entered is not within range and alert would trigger. e.g. If there was 32 pages, "Please enter a value between 1 and 32" Can this be done using jQuery or javascript, by detecting the value change within the range of pages and redirecting to that page? I'm trying to create the same device on Getty Images: http://www.gettyimages.com.au/Search/Search.aspx?contractUrl=2&language=en-US&family=creative&p=ball&assetType=image&clarification=ball%3A60847

  • Need new method for linking to native mapping from mobile web app

    - by Carter
    My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

  • How do I fix this warning in my mx:request tag?

    - by invertedSpear
    I'm running an HTTPService with the following request: <mx:request xmlns=""> <view>{myViewStack.selectedChild.name}</view> </mx:request> The idea being to pass which child is selected on the viewstack to the php page, and then get that back so I can run some logic based on which child of the viewstack was selected at the time. Everything seems to work, but I get the following warning: Data binding will not be able to detect assignments to "name". This doesn't seem to be causing any trouble, but I know warnings usually mean that I am not following the best practice. How can I fix this? I don't really need this item to be bound, because the name will never change at runtime, but I don't know how else to include it in the request.

  • Flex 1009 error Chart datatip

  • Getting HTMLUnknownElement with jQuery.find() and an XML Document

    - by Tom
    I'm attempting to load up an XML document (specifically an RSS feed) via an Ajax request, parse it, and insert some information based on said feed into my page. The code works fine in Firefox, Opera, Chrome, and Safari, but not IE7. Go figure. After doing some initial debugging, I've found that the XML string is being retrieved via the request, and the specific node type I'm getting when trying to parse nodes out of the document is HTMLUnknownElement. Here's the relevant code: $.get('feed.php', function(oXmlDoc) { var titles = $(oXmlDoc).find('title'); var dates = $(oXmlDoc).find('pubDate'); for(var i = 0; i < 5; i++) { parseNodes(titles[i].firstChild.nodeValue, dates[i].firstChild.nodeValue)); } }); The parseNodes function is never actually being hit because IE cannot access firstChild and, consequently, nodeValue. Thanks in advance for any ideas and/or suggestions on how to address this.

  • Int property in class definition

    - by Daniel I-S
    I have the following class structure for custom UITableViewCells: NumericEntryCell - Contains method for controlling max value that can be entered into a textbox. SliderCell - inherits from NEC and contains methods for handling slider-control of textbox value TextOnlyCell - just contains a textbox CellA - inherits from SliderCell and has a max value of 28 CellB - inherits from TextOnlyCell and has a max value of 150. I want NumericEntryCell to contain a definition for a property that contains the maxValue. I want to be able to set a value for this in the initialize method of a child class (CellA or CellB). Currently I have an int maxValue declared in the interface of NEC. I declare a property for this with @property int maxValue and @synthesize it within the .m file. However, attempting to modify this property's value from CellA or CellB's initialize method has no effect - when I hit a breakpoint in the NEC method that uses this value, its value is always zero. How can I get this to work?

  • Selecting data from mysql table and related data from another to join them

    - by knittledan
    Ive looked at other questions and answers but still dont understand which brings me here. I have one data base two tables. lets say table1 and table2 from database. I'm looking to grab all the information from table1 and only one column from table2 that coincides with the correct row in table1. Example which I know is wrong: SELECT table1.*, table2.time_stamp FROM table1, table2 WHERE table1.ticket_id=$var AND table1.user_id = table2.user_id Basically select data from table1 then use a value from the selected table to grab the related data from table2 and join them to output them as one mysql_query. Im sure its simple and has been asked before. edit: I dont receive an error. SQL just returns noting. log form of this would be: $sqlResults = mysql_query("SELECT table1.* FROM table1 WHERE table1.ticket_id=$var") while($rowResult = mysql_fetch_array( $sqlResults )) { $userID = $rowResult['user_id']; $sqlResults2 = mysql_query("SELECT table2.time_stamp FROM table2 WHERE table2.user_id=$userID") } I want to combine that into one sql statement so i dont have to hit table2 for every row table1 has

  • select from multiple tables with different columns

    - by Qaiser Iftikhar
    Say I got this sql schema. Table Job: id,title, type, is_enabled Table JobFileCopy: job_id,from_path,to_path Table JobFileDelete: job_id, file_path Table JobStartProcess: job_id, file_path, arguments, working_directory There are many other tables with varying number of columns and they all got foreign key job_id which is linked to id in table Job. My questions: Is this the right approach? I don't have requirement to delete anything at anytime. I will require to select and insert mostly. Secondly, what is the best approach to get the list of jobs with relevant details from all the different tables in a single database hit? e.g I would like to select top 20 jobs with details, their details can be in any table (depends on column type in table Job) which I don't know until runtime. Thanks in advance. Regards,

  • C#/XNA Giant Memory Leak

    - by user1440926
    this is my first post here. I'm making a game in Visual Studio 2010 using XNA, and i've hit a giant memory leak. My game starts out using 17k ram and then after ten minutes it's upto 65k. I ran some memory profilers, and they all say that new instances of the String object are being created, but they aren't live. The amount of live instances of String hasn't changed at all. It's also creating instances of Char[] (which i'd expect from it), Object[], and StringBuilder. My game is pretty new but there's too much code to post here. I have no idea how to get rid of instances that aren't live, please help!

  • Word VBA: How to know if the actual save operation is completed?

    - by Edwin
    Hi, I am having a problem with the Document.SaveAs method in Word VBA with large Word documents, it seems that the save operation is asynchronous, ie. after calling SaveAs it returns immediately, but with large Word documents the actual save operation may not has been completed and it's in progress in another thread. So what I want to ask is that if there is a way to detect if the actual save operation is in progress or finished? PS. I use Delphi to call the automation interface of Word, if it means something in discussing this problem, but I don't' think so? Thank you in advance.

  • Rails: Thread won't affect database unless joined to main Thread

    - by hatboysam
    I have a background operation I would like to occur every 20 seconds in Rails given that some condition is true. It kicked off when a certain controller route is hit, and it looks like this def startProcess argId = self.id t = Thread.new do while (Argument.isRunning(argId)) do Argument.update(argId) Argument.markVotes(argId) puts "Thread ran" sleep 20 end end end However, this code does absolutely nothing to my database unless I call "t.join" in which case my whole server is blocked for a long time (but it works). Why can't the read commit ActiveRecords without being joined to the main thread? The thread calls methods that look something like def sample model = Model.new() model.save() end but the models are not saved to the DB unless the thread is joined to the main thread. Why is this? I have been banging my head about this for hours.

  • Detecting crosses in an image

    - by MrOrdinaire
    I am working on a program to detect the tips of a probing device and analyze the color change during probing. The input/output mechanisms are more or less in place. What I need now is the actual meat of the thing: detecting the tips. In the images below, the tips are at the center of the crosses. I thought of applying BFS to the images after some threshold'ing but was then stuck and didn't know how to proceed. I then turned to OpenCV after reading that it offers feature detection in images. However, I am overwhelmed by the vast amount of concepts and techniques utilized here and again, clueless about how to proceed. Am I looking at it the right way? Can you give me some pointers? Image extracted from short video Binary version with threshold set at 95

  • Detecting touch area on Android

    - by HappyAppDeveloper
    Is it possible to detect every pixel being touched? More specifically, when the user touches the screen, is it possible to track all the x-y coordinates of the cluster of points touched by the user? How can I tell the difference between when users are drawing with their thumb and when they are drawing with the tip of a finger? I would like to reflect the brush difference depending on how users touch the screen, and would also like to track x-y coordinates of all the pixels being touched over time. Thanks so much in advance for any help.

  • IE 7 CSS problem with detecting mouse over on div

    - by BeaverProj
    I have a div inside an li as part of a top navigation for a website. I'm having trouble with IE 7 having "holes" in the box such that the drop down disappears when the user is still on the drop down. I started with a pure CSS solution (li:hover) and that works awesome in all browsers except IE 7. So I've now added a jQuery/javascript solution to detect when the mouse enters and exits the nav li and then add a class to show the drop down. It works better, but if the mouse is not over an image, p, h3, or a tag then it doesn't think I'm over the div that is the drop down. Very frustrating. I can post some test code, but the issue can be viewed here: http://davincidays.org/ Anyone have any ideas? I've been working on this for waaaay too long already and need some fresh things to try.
