  • Common and useful Graph functions?

    - by Nazgulled
    Hi, I'm implementing a simple Graph library for my uni project and since this is the first time I'm dealing with graphs, I would like to know which functions you guys consider to be most common and useful for Graph implementations... So far, I have this: graphInitialize() graphInsertVertex() graphRemoveVertex() graphGetVertex() graphGetVertexValue() (not implemented yet, not sure if I'll need it) graphInsertEdge() graphRemoveEdge() graphLinkVertices() (this calls graphInsertEdge twice for bidirectional graph) graphUnlinkVertices() (this calls graphRemoveEdge twice for bidirectional graph) graphDestroy() I know I'm missing a function do determine the shortest path, but I'm leaving that for last... Do you think I'm missing any common/useful function?

  • Efficient Map Overlays in on Android Google Map...

    - by Ahsan
    Hi Friends, I want to do the following and am kind of stuck on these for a few days.... 1) I have used helloItemizedOverlay to add about 150 markers and it gets very very slow.....any idea what to do ? I was thinking about threads....(handler) ... 2) I was trying to draw poly lines ( I have encoded polylines, but have managed to decoded those) that move when I move the map.....(the only solution that I found was for Geopoints to be transformed into screen co-ordinates...which wont move if I move the map !) 3) I was looking for some sort of a timer function that executes a given function, say, every 1 minute or so.... 4) I was also looking for ways to clear the Google map from all the markers/lines etc.... Thanks a lot... :) - ahsan

  • Flash to PHP base64 encode/decode

    - by Gus
    I'm using AS3 to base64 encode a JPG and pass it to Javascript. I'm attempting to use AJAX to pass that base64 encoded string to PHP and have PHP decode it. (I know I could send it back to Flash and Flash could decode it and send it to PHP, but I'm trying to eliminate the need for Flash on the decoding end). It appears that AS3's encodeToBase64String() function and and PHP's base64_decode() function do not use the same algorithm, as PHP evaluates it as a base64 encoded object, but does not seem to output it properly. Is there a way to rectify this problem? Note: Please no posts about not needing Javascript. Javascript is a necessary step for reasons not detailed here.

    Hello, Maybe is a often repeated question here, but i can't find anything similar with the search. The point is that i like to use Emacs for my personal projects, usually very small applications using C or python, but i was wondering how to use it also for my work, in which we have project with about 10k files of source code, so is veeeery big (actually i am using source insight, that is very nice tool, but only for windows), questions are: Searching: Which is the most convenient way to search a string within the whole project? Navigating throught the function: I mean something like putting the cursor over a function, define, var, and going to the definition Refactoring Also if you have any experience with this and want to share your thoughts i will consider it highly interesting.

  • Rewriting VB.NET Lambda experession as a C# statement

    - by ChadD
    I downgraded my app from version 4 of the framework to version 4 and now I want to implement this VB.NET lambda function statement (which works on 3.5) Dim colLambda As ColumnItemValueAccessor = Function(rowItem As Object) General_ItemValueAccessor(rowItem, colName) and rewrite it in C#. This was my attempt: ColumnItemValueAccessor colLambda = (object rowItem) => General_ItemValueAccessor(rowItem, colName); When I did this, I get the following error: Error 14 One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll? C:\Source\DotNet\SqlSmoke\SqlSmoke\UserControls\ScriptUserControl.cs 84 73 SqlSmoke However, when I downgraded the app from version 4.0 of the framework to 3.5 (because our users only hae 3.5 and don't have rights to install 4.0). when I did this, the reference to "Microsoft.CSharp" was broken. Can I rewrite the VB.NET command in C# using syntax that is valid in C# 3.5 as I was able to in VB.NET? What would the syntax be?

  • Flex/Flash 4 datagrid displays raw xml

    - by Setori
    Problem: Flex/Flash4 client (built with FlashBuilder4) displays the xml sent from the server exactly as is - the datagrid keeps the format of the xml. I need the datagrid to parse the input and place the data in the correct rows and columns of the datagrid. flow: click on a date in the tree and it makes a server request for batch information in xml form. Using a CallResponder I then update the datagrid's dataProvider. [code] <fx:Script> <![CDATA[ import mx.controls.Alert; [Bindable]public var selectedTreeNode:XML; public function taskTreeChanged(event:Event):void { selectedTreeNode=Tree(event.target).selectedItem as XML; var searchHubId:String = selectedTreeNode.@hub; var searchDate:String = selectedTreeNode.@lbl; if((searchHubId == "") || (searchDate == "")){ return; } findShipmentBatches(searchDate,searchHubId); } protected function findShipmentBatches(searchDate:String, searchHubId:String):void{ findShipmentBatchesResult.token = actWs.findShipmentBatches(searchDate, searchHubId); } protected function updateBatchDataGridDP():void{ task_list_dg.dataProvider = findShipmentBatchesResult.lastResult; } ]]> </fx:Script> <fx:Declarations> <actws:ActWs id="actWs" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/> <s:CallResponder id="findShipmentBatchesResult" result="updateBatchDataGridDP()"/> </fx:Declarations> <mx:AdvancedDataGrid id="task_list_dg" width="100%" height="95%" paddingLeft="0" paddingTop="0" paddingBottom="0"> <mx:columns> <mx:AdvancedDataGridColumn headerText="Receiving date" dataField="rd"/> <mx:AdvancedDataGridColumn headerText="Msg type" dataField="mt"/> <mx:AdvancedDataGridColumn headerText="SSD" dataField="ssd"/> <mx:AdvancedDataGridColumn headerText="Shipping site" dataField="sss"/> <mx:AdvancedDataGridColumn headerText="File name" dataField="fn"/> <mx:AdvancedDataGridColumn headerText="Batch number" dataField="bn"/> </mx:columns> </mx:AdvancedDataGrid> //xml example from server <batches> <batch> <rd>2010-04-23 16:31:00.0</rd> <mt>SC1REVISION01</mt> <ssd>2010-02-18 00:00:00.0</ssd> <sss>100000009</sss> <fn>Revision 1-DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100218.csv</fn> <bn>10041</bn> </batch> <batches> [/code] and the xml is pretty much displayed exactly as is shown in the example above in the datagrid columns...

  • python Socket.IO client for sending broadcast messages to TornadIO2 server

    - by Alp
    I am building a realtime web application. I want to be able to send broadcast messages from the server-side implementation of my python application. Here is the setup: socketio.js on the client-side TornadIO2 server as Socket.IO server python on the server-side (Django framework) I can succesfully send socket.io messages from the client to the server. The server handles these and can send a response. In the following i will describe how i did that. Current Setup and Code First, we need to define a Connection which handles socket.io events: class BaseConnection(tornadio2.SocketConnection): def on_message(self, message): pass # will be run if client uses socket.emit('connect', username) @event def connect(self, username): # send answer to client which will be handled by socket.on('log', function) self.emit('log', 'hello ' + username) Starting the server is done by a Django management custom method: class Command(BaseCommand): args = '' help = 'Starts the TornadIO2 server for handling socket.io connections' def handle(self, *args, **kwargs): autoreload.main(self.run, args, kwargs) def run(self, *args, **kwargs): port = settings.SOCKETIO_PORT router = tornadio2.TornadioRouter(BaseConnection) application = tornado.web.Application( router.urls, socket_io_port = port ) print 'Starting socket.io server on port %s' % port server = SocketServer(application) Very well, the server runs now. Let's add the client code: <script type="text/javascript"> var sio = io.connect('localhost:9000'); sio.on('connect', function(data) { console.log('connected'); sio.emit('connect', '{{ user.username }}'); }); sio.on('log', function(data) { console.log("log: " + data); }); </script> Obviously, {{ user.username }} will be replaced by the username of the currently logged in user, in this example the username is "alp". Now, every time the page gets refreshed, the console output is: connected log: hello alp Therefore, invoking messages and sending responses works. But now comes the tricky part. Problems The response "hello alp" is sent only to the invoker of the socket.io message. I want to broadcast a message to all connected clients, so that they can be informed in realtime if a new user joins the party (for example in a chat application). So, here are my questions: How can i send a broadcast message to all connected clients? How can i send a broadcast message to multiple connected clients that are subscribed on a specific channel? How can i send a broadcast message anywhere in my python code (outside of the BaseConnection class)? Would this require some sort of Socket.IO client for python or is this builtin with TornadIO2? All these broadcasts should be done in a reliable way, so i guess websockets are the best choice. But i am open to all good solutions.

  • newbie question -- how does one override show for a newtype?

    - by gatoatigrado
    I want to override the default integer constructors in Haskell so they produce strings (mostly for curiosity, but temporarily to make a nice input alternative for LaTeX's \frac{}{} inconvenience). I wanted to be able to use the language itself, instead of a special parser, but I guess that's probably not going to work out... module Main where import Prelude hiding ((+)) newtype A = A Int deriving (Eq, Show, Num) default (A) (+) :: A -> (A -> String) (A a) + (A b) = (show a) ++ " + " ++ (show b) main2 = 3+4 main :: IO () main = putStrLn main2 The problem with the above is that the + function only works for (A, A) instead of (A, String), etc. If one simply leaves out the pattern match "(A a)" and writes "a" instead, then the show() function prepends "A " so "3" becomes "A 3" instead of just "3". I want to override Show for A, but it seems to be quite a headache...

  • Using jQuery.getJSON in Chrome Extension

    - by Paul Tarjan
    I need to do a cross-domain request in a chrome extension. I know I can it via message passing but I'd rather stick to just jQuery idioms (so my javascript can also work as a <script src="">). I do the normal: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", callback(function(data) { alert(data); }); but in the error console I see: Uncaught ReferenceError: jsonp1271044791817 is not defined Is jQuery not inserting the callback function correctly into the document? What can I do to make this work?

  • Embedded Javascript in Master Page or Pages That Use Master Page throw "Object Expected Error"

    - by Philter
    I'm semi-new to writing ASP.Net applications using master pages and I've run into an issue I've spent some time on but can't seem to solve. My situation is that I have a master page with a structure that looks like this: <head runat="server"> <title>Test Site</title> <link rel="Stylesheet" type="text/css" href="Default.css" /> <script type="text/javascript" language="javascript" src="js/Default.js" /> <meta http-equiv="Expires" content="0"/> <meta http-equiv="Cache-Control" content="no-cache"/> <meta http-equiv="Pragma" content="no-cache"/> <asp:ContentPlaceHolder ID="cphHead" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form id="form1" runat="server"> <div id="divHeader"> <asp:ContentPlaceHolder ID="cphPageTitle" runat="server"></asp:ContentPlaceHolder> </div> <div id="divMainContent"> <asp:ContentPlaceHolder ID="cphMainContent" runat="server"></asp:ContentPlaceHolder> </div> </div> </form> </body> I then have a page that uses this master page that contains the following: <asp:Content ContentPlaceHolderID="cphHead" runat="server"> <script type="text/javascript" language="javascript" > function test() { alert("Hello World"); } </script> </asp:Content> <asp:Content ContentPlaceHolderID="cphMainContent" runat="server"> <fieldset> <img alt="Select As Of Date" src="Images/Calendar.png" id="aAsOfDate" class="clickable" runat="server" onclick="test();" /> <asp:Button runat="server" CssClass="buttonStyle" ID="btnSubmit" Text="Submit" OnClick="btnSubmit_Clicked"/> </fieldset> </asp:Content> When I run this page and click on the image I get an "Object Expected" error. However, if I place the test function into my Default.js external file it will function perfectly. I can't seem to figure out why this is happening. Any ideas?

    I have the following code: $(document).ready(function(){ $(".yearInner").hide(); $(".year", this).hover( function () { $(".yearInner", this).slideToggle(); } ); }); It hides the div with class yearInner, and then when the containing div with class year is hovered over, the yearInner div toggles on. Works fine, put I'd like to use the hoverIntent plug-in instead of hover. Doesn't work at all with hoverIntent. Suggestions? Div structure for reference: <div class="year"> 2009 <div class="yearInner"> More Info... </div> </div> <div class="year"> 2008 <div class="yearInner"> More Info... </div> </div>

  • QTableWidget signal cellChanged(): distinguish between user input and chage by routines

    - by crabman
    i am using PyQt but my question is a general Qt one: I have a QTableWidget that is set up by the function updateTable. It writes the data from DATASET to the table when it is called. Unfortunately this causes my QTableWidget to emit the signal cellChanged() for every cell. The signal cellChanged() is connected to a function on_tableWidget_cellChanged that reads the contents of the changed cell and writes it back to DATASET. This is necessary to allow the user to change the data manually. So everytime the table is updated, its contents are written back to DATASET. Is there a way to distinguish if the cell was changed by the user or by updateTable? i thought of disconnecting on_tableWidget_cellChanged by updateTable temporarily but that seems to be a little dirty.

  • mingw spitting countless warnings about ignoring "dll import" attribute

    - by hasen j
    I'm using mingw32-make to compile a qt project that uses opengl, it compiles correctly and everything, but it spits countless warning messages of the form: c:/qt3/include/qcolor.h:67: warning: inline function `int qGray(int, int, int)' declared as dllimport: attribute ignored For this particular instance, the function declaration is: Q_EXPORT inline int qGray( int r, int g, int b )// convert R,G,B to gray 0..255 { return (r*11+g*16+b*5)/32; } My question is, why is it spitting all these warning? how can I silence them without silencing other legitimate warnings (i.e. warnings that are related directly to my code and could be potential problems)? More importantly, why is mingw ignoring the dll import attribute in the first place?

  • Best Method for Minimizable Fullscreen Window

    - by kaykun
    Hi, I'm coding a short game in C++ and Win32, and I want to be able to make it in fullscreen with a fixed size. I also want the user to be able to switch focus between the game window and other windows as much as he/she wants without any weird screen glitches. So far I know of the ChangeDisplaySettings function and creating the window with the WS_POPUP style at initialization to make it fullscreen. To detect the user switching focus to other windows by way of alt+tab or otherwise, what messages should I be handling on the window's WndProc or should I be using another function? When loss of focus is detected should I only call ChangeDisplaySettings(NULL, 0); or are there other functions I should call as well? And what method should I use to handle focus back into the window? Also can anyone give me some info on how to make it work smoothly for different screen sizes? Thanks for any help.

  • SignalR recording when a Web Page has closed

    - by Benjamin Rogers
    I am using MassTransit request and response with SignalR. The web site makes a request to a windows service that creates a file. When the file has been created the windows service will send a response message back to the web site. The web site will open the file and make it available for the users to see. I want to handle the scenario where the user closes the web page before the file is created. In that case I want the created file to be emailed to them. Regardless of whether the user has closed the web page or not, the message handler for the response message will be run. What I want to be able to do is have some way of knowing within the response message handler that the web page has been closed. This is what I have done already. It doesnt work but it does illustrate my thinking. On the web page I have $(window).unload(function () { if (event.clientY < 0) { // $.connection.hub.stop(); $.connection.exportcreate.setIsDisconnected(); } }); exportcreate is my Hub name. In setIsDisconnected would I set a property on Caller? Lets say I successfully set a property to indicate that the web page has been closed. How do I find out that value in the response message handler. This is what it does now protected void BasicResponseHandler(BasicResponse message) { string groupName = CorrelationIdGroupName(message.CorrelationId); GetClients()[groupName].display(message.ExportGuid); } private static dynamic GetClients() { return AspNetHost.DependencyResolver.Resolve<IConnectionManager>().GetClients<ExportCreateHub>(); } I am using the message correlation id as a group. Now for me the ExportGuid on the message is very important. That is used to identify the file. So if I am going to email the created file I have to do it within the response handler because I need the ExportGuid value. If I did store a value on Caller in my hub for the web page close, how would I access it in the response handler. Just in case you need to know. display is defined on the web page as exportCreate.display = function (guid) { setTimeout(function () { top.location.href = 'GetExport.ashx?guid=' + guid; }, 500); }; GetExport.ashx opens the file and returns it as a response. Thank you, Regards Ben
