  • SIGABRT Issues with UIApplication_TVOut and MPVideoView - is there another way??

    - by user365920
    Hi there, I am due to do a demo in a week of an app which i have been working on for a company - until now, i have been using code taken from this useful tutorial here The problem is that this no longer seems to be working - causing a SIGABRT inside of the following (see initWithVideoView): - (void) startTVOut; { // you need to have a main window already open when you call start if (!tvoutWindow) { deviceWindow = [self keyWindow]; MPVideoView *vidView = [[MPVideoView alloc] initWithFrame: CGRectZero]; **tvoutWindow = [[MPTVOutWindow alloc] initWithVideoView:vidView];** [tvoutWindow makeKeyAndVisible]; tvoutWindow.userInteractionEnabled = NO; mirrorView = [[UIImageView alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; [self reformatTVOutOrientation]; mirrorView.center = vidView.center; [vidView addSubview: mirrorView]; [deviceWindow makeKeyAndVisible]; [NSThread detachNewThreadSelector:@selector(updateLoop) toTarget:self withObject:nil]; } } Can anyone help at all??? This was all working fine, but seems to have stopped working recently - none of my code has changed, so assuming Apple have removed that API (yes, i know it was a private API in the first place, so im not moaning!) Just need to know if there is an alternative way of displaying the contents of my iPhone screen in my app... Many thanks in advance!

  • C# WebClient OpenRead url

    - by Octopus-Paul
    So i have this program that fetch a page using a short link (I used Google url shortener) to build my example i used the code from Using WebClient in C# is there a way to get the URL of a site after being redirected? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Net; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { MyWebClient client = new MyWebClient(); client.OpenRead("http://tinyurl.com/345yj7x"); Uri uri = client.ResponseUri; Console.WriteLine(uri.AbsoluteUri); Console.Read(); } } class MyWebClient : WebClient { Uri _responseUri; public Uri ResponseUri { get { return _responseUri; } } protected override WebResponse GetWebResponse(WebRequest request) { WebResponse response = base.GetWebResponse(request); _responseUri = response.ResponseUri; return response; } } } I do not understant a thing: when i do client.OpenRead("http://tinyurl.com/345yj7x"); this downloads the page that the url points to? If this method downloads the page, I need something to get me only the url, so if there a method to get only some headers, or only the url please let me know.

  • Why can't I pass an argument to create this window using wxpython?

    - by somefreakingguy
    I am trying to learn how to make a GUI in python! Following an online tutorial, I found that the following code 'works' in creating an empty window: import wx from sys import argv class bucky(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(300, 200)) if __name__=='__main__': app=wx.PySimpleApp() frame=bucky(parent=None,id=-1) frame.Show() app.MainLoop() That gives me a window, which is great. However, what if I want to get an argument passed onto the program to determine the window size? I thought something like this ought to do the trick: import wx from sys import argv script, x, y = argv class mywindow(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x, y)) if __name__=='__main__': app=wx.PySimpleApp() frame=mywindow(parent=None,id=-1) frame.Show() app.MainLoop() But, alas, that does not work! Nor does the raw_input() function pass on the value. I keep getting the following error: C:/Python26/pythonw.exe -u "C:/Documents and Settings/Owner/Desktop/wz.py" File "C:/Documents and Settings/Owner/Desktop/wz.py", line 8 wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x y)) ^ SyntaxError: invalid syntax Thanks for the help!

  • How to make Jtable column contain checkboxes?

    - by theraven
    Preface: I am horrible with java, and worse with java ui components. I have found several different tutorials on how to add buttons to tables, however I am struggling with adding checkboxes. I need to have a column that draws a text box ticked on default (cell renderer i think handles that), then on click of tickbox, unticks the box, redraws said box, and fires off an event somewhere I can track. currently I have a custom cellrenderer: public class GraphButtonCellRenderer extends JCheckBox implements TableCellRenderer { public GraphButtonCellRenderer() { } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if(isSelected) setSelected(true); else setSelected(false); setMargin(new Insets(0, 16, 0, 0)); setIconTextGap(0); setBackground(new Color(255,255,255,0)); return this; }} Which currently handles drawing the tick box, but only ticks and unticks the box if that row is selected. But I don't know how to handle the events. Really what I am asking is possibly a link to a good tutorial on how to add checkboxes cleanly to a JTable. Any assist is greatly appreciated :)

  • Entity Framework and stored procedure returning temp table Issues

    - by kaplooeymom
    (Disclaimer - I'm not the database designer. I'm just the poor developer what has to make this work.) There are 17 (at the moment) tables with identical structure - name, address, phone number. Given a phone number, I have to check to see if there's a matching entry in any of the tables, then return that address. So, I created a view to get the list of tables (there's a ref table that holds that info), then I created a stored procedure to create a temp table, using cursors, check each table in the view for the phone number, using sql concatenation. If a record is found, insert it into the temp table. return the rows from the temp table. This all works in straight T-SQL. Now, I'm trying to use Entity Framework 4+ to call the stored procedure. But the function import interface won't generate columns. It says return type = none, and the LINQ code expects an int and won't compile. Any ideas on how to make this work? I know I can move the check tables part to code, if I absolutely have to, but I'd rather have the above method work.

  • WPD on XP, Vista, and 7 (need to transfer photo and video files)

    - by Bradley Dean
    I need to transfer files (still photos and videos) from any portable device that a user may connect (still camera, video camera, mobile phone, etc.) I don't need to worry about plain storage devices as these have drive letters. And I only care about existing files, I don't care about live video, preview video, taking new pictures, etc. I originally tried WIA, which works great except it can not transfer video files. So then I tried WPD, following along with dimeby8's tutorial: http://blogs.msdn.com/b/dimeby8/archive/2006/09/27/774259.aspx I haven't gotten the transfer working yet (I'm converting it over to C#), but I can at least see the device and enumerate the files in Win7. In XP I get nothing. It's pointed out in this thread that WPD won't enumerate devices on XP (see Lisa O [MSFT]'s post): http://social.msdn.microsoft.com/Forums/en/windowssdk/thread/56459945-b757-45df-8c9f-4ebdbbb18a2c So WIA is out because it won't do video. And WPD is out because it won't do XP. Has anyone gotten this to work? Am I missing something simple here? Thanks.

  • Ruby ICalendar Gem: How to get e-mail reminders working.

    - by Jenny
    I'm trying to work out how to use the icalendar ruby gem, found at: http://icalendar.rubyforge.org/ According to their tutorial, you do something like: cal.event.do # ...other event properties alarm do action "EMAIL" description "This is an event reminder" # email body (required) summary "Alarm notification" # email subject (required) attendees %w(mailto:[email protected] mailto:[email protected]) # one or more email recipients (required) add_attendee "mailto:[email protected]" remove_attendee "mailto:[email protected]" trigger "-PT15M" # 15 minutes before add_attach "ftp://host.com/novo-procs/felizano.exe", {"FMTTYPE" => "application/binary"} # email attachments (optional) end alarm do action "DISPLAY" # This line isn't necessary, it's the default summary "Alarm notification" trigger "-P1DT0H0M0S" # 1 day before end alarm do action "AUDIO" trigger "-PT15M" add_attach "Basso", {"VALUE" => ["URI"]} # only one attach allowed (optional) end So, I am doing something similar in my code. def schedule_event puts "Scheduling an event for " + self.title + " at " + self.start_time start = self.start_time endt = self.start_time title = self.title desc = self.description chan = self.channel.name # Create a calendar with an event (standard method) cal = Calendar.new cal.event do dtstart Program.convertToDate(start) dtend Program.convertToDate(endt) summary "Want to watch" + title + "on: " + chan + " at: " + start description desc klass "PRIVATE" alarm do action "EMAIL" description desc # email body (required) summary "Want to watch" + title + "on: " + chan + " at: " + start # email subject (required) attendees %w(mailto:[email protected]) # one or more email recipients (required) trigger "-PT25M" # 25 minutes before end end However, I never see any e-mail sent to my account... I have even tried hard coding the start times to be Time.now, and sending them out 0 minutes before, but no luck... Am I doing something glaringly wrong?

  • Cache consistency & spawning a thread

    - by Dave Keck
    Background I've been reading through various books and articles to learn about processor caches, cache consistency, and memory barriers in the context of concurrent execution. So far though, I have been unable to determine whether a common coding practice of mine is safe in the strictest sense. Assumptions The following pseudo-code is executed on a two-processor machine: int sharedVar = 0; myThread() { print(sharedVar); } main() { sharedVar = 1; spawnThread(myThread); sleep(-1); } main() executes on processor 1 (P1), while myThread() executes on P2. Initially, sharedVar exists in the caches of both P1 and P2 with the initial value of 0 (due to some "warm-up code" that isn't shown above.) Question Strictly speaking – preferably without assuming any particular CPU – is myThread() guaranteed to print 1? With my newfound knowledge of processor caches, it seems entirely possible that at the time of the print() statement, P2 may not have received the invalidation request for sharedVar caused by P1's assignment in main(). Therefore, it seems possible that myThread() could print 0. References These are the related articles and books I've been reading. (It wouldn't allow me to format these as links because I'm a new user - sorry.)

  • Display gridview in new window

    - by Ricardo Deano
    Hello all. Just a bit of advice needed really in terms of how I should handle my current scenario: I have a web page that searches for products/category information the results of which are at present displayed in a gridview on the same page. However, said gridview is a bit of a beast and as such, I would like to have a page that the user searches for, a button is pressed and the subsequent gridview is displayed in a new window. Ultimately, I would like the user to be able to make multiple searches so that new windows can have multiple gridviews containing different data sets. My current thinking is to create session variables that can be pulled through onto 'the gridview page'. Having said that, I'm not sure that would work if multiple searches are created? I am also thinking I might be able to create said 'gridview window' using javascript but my concern here is the potential loss of functionality of the gridview i.e. paging, sorting, editing, etc. Does anyone have any thoughts or theories on this? What would be "best practise"? Any thoughts greatly appreciated and taken on board. PS: This is being developed in .net, using c# and LINQ. PPS: I'm a noob so be gentle!!

  • sIFR 3 rev 436 - copy link to clipboard

    - by Alan Forsyth
    This was originally a question, but is now a code enhancement, since it's a very minor (but useful) update. When heading (or other) text is used as a link with sIFR 3, you now get the two 'open link / open link in new window' options in the right-click flash context menu for the link. When I came across sIFR for the first time yesterday, I was wanting to copy a header (h2) link to the clipboard, on a site that used sIFR 2.x, and was frustrated that I couldn't. Thanks to the wonders of open source (and well written code), I can suggest the following enhancement to sIFR 3: [In the file flash/sIFR.as, find the section starting with the comment "// Have to set up menu items first!" through to ");" and replace with the following, then add font information to the .fla and export the swf as per the tutorial:] // Have to set up the menu items first! menuItems.push( new ContextMenuItem("Follow link", function() { getURL(sIFR.instance.primaryLink, sIFR.instance.primaryLinkTarget) }), new ContextMenuItem("Open link in new window", function() { getURL(sIFR.instance.primaryLink, "_blank") }), new ContextMenuItem("Copy link to clipboard", function() { System.setClipboard(sIFR.instance.primaryLink) }) ); Now I'm happy... :-) Alan.

  • How could I parse this HTML file?

  • VS2010 express beta2 - no add reference dialog, no open file/project dialogs

    - by David
    Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.

  • How can I do rapid application development with ASP.NET MVC?

    - by Erik Forbes
    I've been given a short amount of time (~80 hours to start with) to replace an existing Access database with a full-blown SQL + Web system, and I'm enumerating my options. I would like to use ASP.NET MVC, but I'm unsure of how to use it effectively with my short timetable. For the database backend I'll be using Linq to SQL as it's a product I already know and can get something working with it quickly. Does anyone have any experience with using ASP.NET MVC in this way and can share some insight? Edit: The reason I've been interested in ASP.NET MVC is because I know (100% confirmed) that there will be more work to do after this first round, and I'd like my maintenance work to be as easy as possible. In my experience Webforms applications tend to break down over repeated maintenance, despite discipline. Maybe there's a middle ground? How difficult would it to be for me to, say, build the app with Webforms, then migrate it to MVC later when I have more time budgeted to the project? Edit 2: Further background: the Access application I'm replacing is used in some capacity by everyone in the building, and since it was upgraded from Access 98 to 2003 it's been crashing daily, causing hours of lost productivity as people have to re-enter data since the last backup. This is the reason for the short amount of time - this is a critical business function, and they can't afford to keep re-entering data on a daily basis.

  • C++ boost.asio server and client connection undersanding

    - by Edgar Buchvalov
    i started learning boost.asio and i have some problems with undersanding tcp connections. There is example from official boost site: #include <ctime> #include <iostream> #include <string> #include <boost/asio.hpp> using boost::asio::ip::tcp; std::string make_daytime_string() { using namespace std; // For time_t, time and ctime; time_t now = time(0); return ctime(&now); } int main() { try { boost::asio::io_service io_service; tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 13)); for (;;) { tcp::socket socket(io_service); acceptor.accept(socket); std::string message = make_daytime_string(); boost::system::error_code ignored_error; boost::asio::write(socket, boost::asio::buffer(message), boost::asio::transfer_all(), ignored_error); } } catch (std::exception& e) { std::cerr << e.what() << std::endl; } return 0; } there is question, why if i want to connet to this server via client i have t write: boost::asio::io_service io_service; tcp::resolver resolver(io_service); tcp::resolver::query query(host_ip, "daytime"); //why daytime? tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::resolver::iterator end; why daytime?, what it meant and where it is inicialized in server, or i just doesn't missed somefing? there is full client code : www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/tutorial/tutdaytime1.html thanks for explanation in advance

  • Hybrid EAV/CR model via WCF (and statically-typed language)?

    - by Pat
    Background I'm working on the architecture for a cloud-based LOB application, using Silverlight for the client, WCF, ASP.NET/C# for server and SQL Server for storage. The data model requires some flexibility per user (ability to add custom properties and define validation rules for them, for example), and a hybrid EAV/CR persistence model on the server side will suit nicely. Problem I need an efficient and maintainable technology and approach to handle the transformation from the persisted EAV model to/from WCF (and similarly allow the client to bind to the resulting data - DataGrid is a key UI element)? Admission: I don't yet know enough about WCF to understand if it supports ExpandoObject directly, but I suspect it will. Options I started off looking at WCF RIA services, but quickly discovered they're heavily dependent upon both static type data and compile-time code generation. Neither of these appeal. The options I'm considering include: Using WCF RIA services and pass the data over the network directly in EAV form (i.e. Dictionary), and handle the binding issue purely on the client side (like this) Using a dynamic language (probably IronPython) to handle both ends of the communication, with plumbing to generate the necessary CLR type data on the client to allow binding, and transform to/from EAV form on the server (spam preventer stopped me from posting a URL here, I'll try it in a comment). Dynamic LINQ (CreateClass() and friends), although I'm way out of my depth there and don't know what the limitations on that approach might be yet. I'm interested in comments on these approaches as well as alternative approaches that might solve the problem. Other Notes The Silverlight client will not be the only consumer of the service, making me slightly uncomfortable with option #1 above. While the data model is flexible, it's not expected to be modified heavily. For argument's sake, we could assume that we might have 25 distinct data models active at a given time, with something like 10-20 unique data fields/rules each. Modifications to the data model will happen infrequently (typically when a new user is initially configured).

  • Modifying NSMutableDictionary from a single index format into nested (array within array)

    - by Michael Robinson
    I need to take the member ID off the top of this and create an array inside that contains the rest of the JSON return. Here is my JSON return. [{"F_Name_VC":"Frank", "L_Name_VC":"Johnson", "userid":"18", "age":"23", },] After it is json-deserialized it looks like this: I need convert it to be transformed into this, with children sub-array: Someone else posted a similar question but without the fact that it was coming from a JSON deserialization. There were two answers but no conclusion to the question. (Answer 1): NSDictionary *item1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@" member",[NSNumber numberWithInt:3],nil] forKeys:[NSArray arrayWithObjects:@"Title",@"View",nil]]; Answer (2): NSMutableArray *Rows = [NSMutableArray arrayWithCapacity: 1]; for (int i = 0; i < 4; ++i) { NSMutableArray *theChildren = [NSMutableArray arrayWithCapacity: 1]; [theChildren addObject: [NSString stringWithFormat: @"tester %d", i]]; NSString *aTitle = [NSString stringWithFormat: @"Item %d", i]; NSDictionary *anItem = [NSDictionary dictionaryWithObjectsAndKeys: aTitle, @"Title", theChildren, @"Children"]; [Rows addObject: anItem]; } NSDictionary *Root = [NSDictionary withObject: Rows andKey: @"Rows"]; Here is my JSON return and save code: NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; if (dict) { rowsArray = [dict objectForKey:@"member"]; [rowsArray retain]; } Thanks in advance. Every tutorial on JSON only shows a simple array being returned, never with children..It's driving me crazy trying to figure this out.

  • WPF: How to connect to a sql ce 3.5 database with ADO.NET?

    - by EV
    Hi, I'm trying to write an application that has two DataGrids - the first one displays customers and the second one selected customer's records. I have generated the ADO.NET Entity Model and the connection property are set in App.config file. Now I want to populate the datagrids with the data from sql ce 3.5 database which does not support LINQ-TO-SQL. I used this code for the first datagrid in code behind: CompanyDBEntities db; private void Window_Loaded(object sender, RoutedEventArgs e) { db = new CompanyDBEntities(); ObjectQuery<Employees> departmentQuery = db.Employees; try { // lpgrid is the name of the first datagrid this.lpgrid.ItemsSource = departmentQuery; } catch (Exception ex) { MessageBox.Show(ex.Message); } However, the datagrid is empty although there are records in a database. It would also be better to use it in MVVM pattern but I'm not sure how does the ado.net and MVVM work together and if it is even possible to use them like that. Could anyone help? Thanks in advance.

  • Using Custom MapType with Google Maps API

    - by Pat Long - Munkii Yebee
    I realise there are a couple of examples such as Maoki's Add Your Own Custom Map and Mike Williams' [link text][Google Maps API Tutorial] however I have looked at these and still end up with a Grey box. The API will not call my "getTileUrl" callback function. This is the javascript I am using var map = new GMap2(document.getElementById("map")); map.setUIToDefault(); var copyCollection = new GCopyrightCollection('Map Data:'); var copyright = new GCopyright(1, new GLatLngBounds(new GLatLng(-90, -180), new GLatLng(90, 180)), 0, "©2006 RunwayFinder.com"); copyCollection.addCopyright(copyright); var tilelayers = [new GTileLayer(copyCollection, 3, 11)]; tilelayers[0].getTileUrl = function (a, b) { var z = 17 - b; var f = "http://localhost:25213/test.jpg?x=" + a.x + "&y=" + a.y + "&zoom=" + z + "&width=100&height=100"; return f; }; var custommap = new GMapType(tilelayers, new GMercatorProjection(12), "Chart", { errorMessage: "No chart data available" }); map.addMapType(custommap); Can anyone see what it is i am doing wrong?

  • Setting Up OpenCV and .lib files

    - by jhaip
    I have been trying to set up OpenCV for the past few days with no results. I am using Windows 7 and VS C++ 2008 express edition. I have downloaded and installed OpenCV 2.1 and some of the examples work. I downloaded CMake and ran it to generate the VS project files and built all of them but there with several errors, and couldn't get any farther than that. When I ran CMake I configured it to use the VS 9 compiler, and then it brought up a list of items in red such as BUILD_EXAMPLES, BUILD_LATEX_DOCS, ect. All of them were unchecked except BUILD_NEW_PYTHON_SUPPORT, BUILD_TESTS, ENABLE_OPENMP, and OPENCV_BUILD_3RDPARTY_LIBS. I configured and generate without changing anything and then it generated the VS files such as ALL_BUILD.vcproj. I built the OpenCV VS solution in debug mode and it had 15 failures (maybe this is part of the problem or is it because I don't have python and stuff like that?) Now there was a lib folder created after building but inside there was just this VC++ Minimum Rebuild Dependency file and Program Debug Database file, both called cvhaartraining. I believe it should have created the .lib files I need instead of this. Also, the bin folder now has a folder called Debug with the same types of files with names like cv200d and cvaux200d. Believe I need those .lib files to move forward. I would also greatly appreciate if someone could direct me to a reliable tutorial to set up VS for OpenCV because I have been reading a lot of tutorials and they all say different things such as some say to configure Window's environment variables and other say files are located in folders such as OpenCV/cv which I don't have. I have gotten past the point of clear headed thinking so if anyone could offer some direction or a simple list of the files I need to link then I would be thankful. Also a side question: why when linking the OpenCV libs do you have to put them in quotes?

Edit: This is the part of the code that generate the error: package = (Package *)[NSEntityDescription insertNewObjectForEntityForName:@"Package" inManagedObjectContext:moc]; theNodes = [doc nodesForXPath:@"//pack" error:&error]; for (CXMLElement *theElement in theNodes) { // Create a counter variable as type "int" int counter; // Loop through the children of the current node for(counter = 0; counter < [theElement childCount]; counter++) { if([[[theElement childAtIndex:counter] name] isEqualToString: @"id"]) [package setIdPackage:[[theElement childAtIndex:counter] stringValue]]; if([[[theElement childAtIndex:counter] name] isEqualToString: @"title"]) [package setPackageTitle:[[theElement childAtIndex:counter] stringValue]]; if([[[theElement childAtIndex:counter] name] isEqualToString: @"category"]) [package setCategory:[[theElement childAtIndex:counter] stringValue]]; if([[[theElement childAtIndex:counter] name] isEqualToString: @"lang"]) [package setLang:[[theElement childAtIndex:counter] stringValue]]; if([[[theElement childAtIndex:counter] name] isEqualToString: @"number"]) { NSNumberFormatter * f = [[NSNumberFormatter alloc] init]; [f setNumberStyle:NSNumberFormatterDecimalStyle]; NSNumber * myNumber = [f numberFromString:[[theElement childAtIndex:counter] stringValue]]; [f release]; [package setNumber:myNumber]; } } } NSLog([NSString stringWithFormat:@"=== %s ===\nID: %s\nCategory: %s\nLanguage: %s",[package packageTitle], [package idPackage] ,[package category],[package lang]]);

  • Why can't I define a case-insensitve Dictionary in C#?

    - by Edward Tanguay
    This WPF code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; namespace TestDict28342343 { public partial class Window1 : Window { public Window1() { InitializeComponent(); Dictionary<string, string> variableNamesAndValues = new Dictionary<string, string>(StringComparison.InvariantCultureIgnoreCase); } } } gives me the error: The best overloaded method match for 'System.Collections.Generic.Dictionary.Dictionary(System.Collections.Generic.IDictionary)' has some invalid arguments Yet I find this code example everywhere such as here and here. How can I define a Dictionary whose keys are case-insensitve?

  • How to distinguish between two different UDP clients on the same IP address?

    - by Ricket
    I'm writing a UDP server, which is a first for me; I've only done a bit of TCP communications. And I'm having trouble figuring out exactly how to distinguish which user is which, since UDP deals only with packets rather than connections and I therefore cannot tell exactly who I'm communicating with. Here is pseudocode of my current server loop: DatagramPacket p; socket.receive(p); // now p contains the user's IP and port, and the data int key = getKey(p); if(key == 0) { // connection request key = makeKey(p); clients.add(key, p.ip); send(p.ip, p.port, key); // give the user his key } else { // user has a key // verify key belongs to that IP address // lookup the user's session data based on the key // react to the packet in the context of the session } When designing this, I kept in mind these points: Multiple users may exist on the same IP address, due to the presence of routers, therefore users must have a separate identification key. Packets can be spoofed, so the key should be checked against its original IP address and ignored if a different IP tries to use the key. The outbound port on the client side might change among packets. Is that third assumption correct, or can I simply assume that one user = one IP+port combination? Is this commonly done, or should I continue to create a special key like I am currently doing? I'm not completely clear on how TCP negotiates a connection so if you think I should model it off of TCP then please link me to a good tutorial or something on TCP's SYN/SYNACK/ACK mess. Also note, I do have a provision to resend a key, if an IP sends a 0 and that IP already has a pending key; I omitted it to keep the snippet simple. I understand that UDP is not guaranteed to arrive, and I plan to add reliability to the main packet handling code later as well.

  • How to install Eclipse + PHP Development Tools (PDT) + Debugger on Mac in The Year 2010

    - by aphex5
    I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

  • [Python] name 'OptionGroup' is not defined

    - by Cawas
    Ok, so I made this rookie mistake below, but in my defense I was led to it thanks to how the help about this subject is on python docs, which states how to use optparse. It is actually an error under the gigantic tutorial section. In contrast and to my offense, I may be one of the very few stupid people who can't read very well and pay close attention on what I do. But since this took me so long to discover, I wanted to "document" it here: Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) >>> from optparse import OptionParser >>> outputGroup = OptionGroup(parser, 'Output handling') Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'OptionGroup' is not defined This is strictly done with examples found on the docs, and you can't find anything about it anywhere, be it that long long docs page, google or stackoverflow. Plus, reading optparse.py shows OptionGroup is there, so that adds to the confusion. I bet it will take less than 1 minute for someone to spot my error. For that I'll only add proper tags and / or modify the title later on. :)

  • How to implement an ListView containing images with style

    - by Alexandergre
    So I have been working with an app where I need to show the thumbnails as clean and use the space in a good way. Style A is my work until now. What I want to accomplish is something like style B. no titles and use the space in a good way. I need help with this. there was no tutorial on the net. Is ListView able to do such a thing? or shall I make picturesboxes and put them in a scrollview? the code: private void button1_Click(object sender, EventArgs e) { ImageList myImageList = new ImageList(); myImageList.ImageSize = new Size(48, 48); DirectoryInfo dir = new DirectoryInfo(@"C:\img"); foreach (FileInfo file in dir.GetFiles()) { try { myImageList.Images.Add(Image.FromFile(file.FullName)); } catch { Console.WriteLine("This is not an image file"); } } myListView.LargeImageList = myImageList; myListView.Items.Add("a", 0); myListView.Items.Add("b", 1); myListView.Items.Add("c", 2);
