• printable PHP manual - 'all but the Function Reference section'

  - by JW01

  My Motivation I find it easier to learn things by reading 'offline'. I'd like to lean back and read the narrative part of a paper version of the official php manual. My Scuppered Plan My plan was to download the manual, print all but the Function Reference section and then read it. I have downloaded the "Single HTML file" version of the manual from the php.net download page. (That version did not contain any images, so I patched-in the ones from the Many HTML files version with no problem.) My plan was to open that "Single HTML file" in an HTML editor, delete the Function Reference section then print it out. Unfortunately, although I have tried three different editors, I have not been able to successfully load-up that massive html file to be able to edit it. Its about (~40MB). I started to look into the phpdoc framework with a view to rendering my own html docs from the source...but that's a steep learning curve for a newby..and is a last resort. I would use a file splitter, but they tend to split files crudely with no regard for html/xml/xhtml sematics. So the question is... Does anyone know know where you can download the php manual in a version that is a kind of half-way house between the 'Single HTML file' and the 'Many HTML files'? Ideally with the docs split into 3 parts: File 1 - stuff before the function reference File 2 - function reference File 3 - stuff after the function reference Or Can you suggest any editors/tools will enable me to split up this file myself?

• Algorithm to reduce calls to mapping API

  - by aidan

  A random distribution of points lies on a map. This data lies behind an API, and I want to grab the complete set of points within a given bounding box. I can query the API with the bounding box and the API will return the set of points that fall within that box. The problem is that the API will limit the result set to 10 items, with no pagination and no indication if there are more points that have been omitted. So I made a recursive algorithm that takes a bounding box and requests the points that lie within it. If the result set is exactly 10 items, then I split the bounding box into four quadrants and recurse. It works fine but my question is this: if want to minimize the number of API calls, what is the optimal way to split the bounding box? Splitting it into quadrants was just an arbitrary decision. When there are a lot of points on the map, I have to drill down many levels before I start getting meaningful results. So I imagine it might be faster to split the box into, say, 9, 16, or more sections. But if I do that, then I eventually get to a point where a lot of requests are returning 0 results which isn't so efficient. Also, does the size of the limit on the results set affect the answer? (This is all assuming that I have no prior knowledge of nominal point density in the bounding box)

• Hosting several HTTP servers on single domain name

  - by Nakilon

  Several people have got a single domain name server.company.com server, where they are now supposed to host their infrastructure or temporal projects, written in different ways even in different programming languages. How do they divide the domain? Split into subdomains: john.server.company.com, kate.server.company.com, etc. This would need a lot of admins' assistance, time, etc. -- there would be no way for John and Kate to do it themselves. Split into url namespaces: server.company.com/john/, server.company.com/kate/, etc. Pro: They now can make a single welcome page at root with any additional info (if they need?) Con: Each server would need to know their namespace string constant, and hrefs like / whould need patching. Split into ports: server.company.com:8080, server.company.com:8081, etc. and make a single :80 welcome page. Pro: They still can make a single welcome page at :80 Con: ??? I would like to know more pros and cons for 2 and 3 solution.

• Possible to draw a select portion of a render target? (in XNA)

  - by TheBroodian

  I'm going to try to do this in reverse fashion and skip straight to the punch line, and then give the back story afterward: Is it possible to, after drawing a scene to a RenderTarget2D, only draw a select portion of the RenderTarget2D, if I don't want the entire thing? I'm using xTile to manage world data in my game (it's a great piece of work, colinvella [xTile's author] has made an amazing product), and for the most part it works great. xTile supports parallax effects in its layers to add some wonderful depth to 2d scenes, which was great, until I implemented a dynamic split-screen system into my game. Wanted to make a co-op game that wouldn't require players to be in close proximity to each other, so I made it so that if the players separate too far apart, the singular full-screen viewport 'snaps-apart', and is replaced by two split-screen viewports, which then smoothly transition to their respective player targets. The effect is pretty smooth aside from the part where the parallax backgrounds become skewed once the viewports split, because xTile's ratio for handling parallax effects is dependent upon viewport size. This is unfortunate, because the effect would otherwise be really snazzy, but the backgrounds become pretty heavily affected when the game goes from single-viewport to multi-viewport. So, Colinvella suggests using rendertargets to record the scene at full viewport size, and then only drawing a portion of it. But as far as I can tell, that isn't even possible? That being said, I've never even used render targets before, so I'm still learning, hence the question here.

• Manage Files Easier With Aero Snap in Windows 7

  - by Mysticgeek

  Before the days of Aero Snap you would need to arrange your Windows in some weird way to see all of your files. Today we show you how to quickly use the Aero Snap feature get it done in few key strokes in Windows 7. You can of course navigate the windows in Explorer to get them so you can see everything side by side, or use a free utility like Cubic Explorer.   Getting Explorer Windows Side by Side The process is actually simple but quite useful when looking for a large amount of data. Right-click the Windows Explorer icon on the taskbar and click Windows Explorer. Our first window opens up and you can certainly drag it over the the right or left side of the screen but the quickest method we’re using is the “Windows Key+Right Arrow” key combo (make sure to hold the Windows key down). Now the Windows is nicely placed on the right side. Next we want to open the other window, simply right-click the Explorer icon again and click Windows Explorer.   Now we have our second window open, and all we need to do this time is use the Windows Key+Left Arrow combination. There we go! Now you should be able to browse your files a lot more simply than relying on the expanding tree method (as much). You can actually use this method to snap a window to all four corners of your screen if you don’t feel like dragging it. Once you play with Aero Snap more you may enjoy it, but if you still despise it, you can disable it too!

• Microsoft JScript runtime error in Visual studio 2010

  - by anirudha

  There is many tool exist to debug JavaScript visual studio , firebug and some other great plugin are one of them. here I show you solution for Microsoft JScript runtime error: Object doesn't support this property or method  if you search on Google for how to debug Javascript in Visual studio. all of them told you to follow this instruction :- go to Internet option in IE > advanced tab > Browsing section > uhcheck the both option disable script debugging for IE (internet explorer) disable script debugging (others). that’s the information you read are outdate or not true these days. in visual studio you can play with JavaScript debugging even these option is check or unchecked. off-course you  can try these step in express version of visual studio. I found a little problem that my code [based on jQuery plugin] try to call some function. some of them not implement in browser so they call other so that’s fine and work in every browser. when visual studio found some function they trying to call and not implemented in browser I use to debug they tell me Microsoft JScript runtime error: Object doesn't support this property or method  they tell me again whenever I put refresh [f5] in browser. so the thing they do you never like that. see error window first whenever code is not buggy and see everytime before see the page you want to see. this behavior harsh you. there is no problem whenever you not commonly used IE but whenever you really want to debugging you got some pain too from the behavior of this. well I have some patch for that if you really like the debugging in Visual studio with IE. so if you sure that code is not buggy or you really not want to see that’s window here is trick. when you debug the JavaScript in IE choose the compact mode and they never force you to see window first who tell the thing you not want to see. How to do that for reliefs from this pain in visual studio after debug the project or website IE gone automatically launch. go to Developer tool by pressing f12 > you see window something like this:- by the way they give you document mode IE 7 as default or browser mode based on your settings. first thing is that you need to set the compact view [any ] in browser mode. and next time the error window never come again who tell you Microsoft JScript runtime error: Object doesn't support this property or method

• GNU/Linux interactive table content GUI editor?

  - by sdaau

  I often find myself in the need to gather data (say from the internet), into a table, for comparison reasons. I usually need the final table output in HTML or MediaWiki mostly, but often times also Latex. My biggest problem is that I often forget the correct table syntax for these markup languages, as well as what needs to be properly escaped in the inline data, for the table to render correctly. So, I often wish there was a GUI application, which provides a tabular framework - which I could stick "Always on Top" as a desktop window, and I could paste content into specific cells - before finally exporting the table as a code in the correct language. One application that partially allows this is Open/LibreOffice calc: The good thing here is that: I can drag and drop browser content into a specifically targeted table cell (here B2) "Rich" text / HTML code gets pasted For long content, the cell (column) width stays put as it originally was The bad thing is, that: when the cell height (due to content size) becomes larger than the calc window, it becomes nearly impossible to scroll calc contents up and down (at least with the mousewheel), as the view gets reset to top-right corner of the selected cell calc shows an "endless"/unlimited field of cells, so not exactly a "table" - which I find visually very confusing (and cognitively taxing) Can only export table to HTML What I would need is an application that: Allows for a limited size table, but with quick adding of rows and columns (e.g. via corresponding + buttons) Allows for quick setup of row and column height and width (as well as table size) Stays put at those sizes, regardless of size of content pasted in; if cell content overflows, cell scrollbars are shown (cell content could be possibly re-edited in a separate/new window); if table overflows over window size, window scrollbars are shown Exports table in multiple formats (I'd need both HTML and mediawiki), properly escaping cell content for each (possibility to strip HTML tags from content pasted in cells, to get plain text, is a plus) Targeting a specific cell in the table for the content paste operation is a must - it doesn't have to be drag'n'drop though, a right click over a cell with "Paste content" is enough. I'd also want the ability to click in a specific cell and type in (plain text) content immediately. So, my question is: is there an application out there that already does something like this? The reason I'm asking is that - as the screenshots show - for instance Libre/OpenOffice allows it, but only somewhat (as using it for that purpose is tedious). I know there exist some GUI editors for Linux (both for UI like guile or HTML like amaya); but I don't know them enough to pinpoint if any of them would offer this kind of functionality (and at least in my searches, that kind of functionality, if present in diverse software, seems not to be advertised). Note I'm not interested in styling an HTML table, which is why I haven't used "table designer" in the title, but "table editor" (in lack of better terms) - I'm interested in (quickly) adjusting row/column size of the table, and populating it with pasted data (which is possibly HTML) in a GUI; and finally exporting such a table as self-contained HTML (or other) code.

• How to Enable JavaScript file API in IE8 [closed]

  - by saeed

  i have developed a web application in asp.net , there is a page in this project which user should choose a file in picture format (jpeg,jpg,bmp,...) and i want to preview image in the page but i don't want to post file to server i want to handle it in client i have done it with java scripts functions via file API but it only works in IE9 but most of costumers use IE8 the reason is that IE8 doesn't support file API is there any way to make IE8 upgrade or some patches in code behind i mean that check if the browser is IE and not support file API call a function which upgrades IE8 to IE9 automatically. i don't want to ask user to do it in message i want to do it programmatic !! even if it is possible install a special patch that is required for file API because customers thought it is a bug in my application and their computer knowledge is low what am i supposed to do with this? i also use Async File Upload Ajax Control But it post the file to server any way with ajax solution and http handler but java scripts do it all in client browser!!! following script checks the browser supports API or not <script> if (window.File && window.FileReader && window.FileList && window.Blob) document.write("<b>File API supported.</b>"); else document.write('<i>File API not supported by this browser.</i>'); </script> following scripts do the read and Load Image function readfile(e1) { var filename = e1.target.files[0]; var fr = new FileReader(); fr.onload = readerHandler; fr.readAsText(filename); } HTML code: <input type="file" id="getimage"> <fieldset><legend>Your image here</legend> <div id="imgstore"></div> </fieldset> JavaScript code: <script> function imageHandler(e2) { var store = document.getElementById('imgstore'); store.innerHTML='<img src="' + e2.target.result +'">'; } function loadimage(e1) { var filename = e1.target.files[0]; var fr = new FileReader(); fr.onload = imageHandler; fr.readAsDataURL(filename); } window.onload=function() { var x = document.getElementById("filebrowsed"); x.addEventListener('change', readfile, false); var y = document.getElementById("getimage"); y.addEventListener('change', loadimage, false); } </script>

• Monitor the Weather from Your Windows 7 Taskbar

  - by Asian Angel

  Keeping up with the weather forecast can be hard when you are extra busy with work. If you need a simple but nice looking way to integrate weather monitoring into your Taskbar then join us as we look at WeatherBar. Setting Up & Using WeatherBar To get started unzip the following files, place them in an appropriate “Program Files Folder”, and create a shortcut. When you start WeatherBar for the first time you will be presented with the following window and a random/default location. To get WeatherBar set up for your location there are only two settings to adjust (using the “Pencil & Gear Buttons”). Clicking on the “Pencil Button” will open up this small window…enter the name of your location and click “OK”. Next click on the “Gear Button” where you can choose the “Update Interval” and “Measurement Format” that best suits your needs. Click “OK” when finished and WeatherBar will be ready to go. That definitely looks nice. When you are finished viewing this window minimize it to the “Taskbar Icon” instead of clicking on the “Close Button”…otherwise the entire app will close. Left click on the “Taskbar Icon” to bring the window back up… Hovering the mouse over the “Taskbar Icon” provides a nice thumbnail of the weather forecast. Right clicking on the “Taskbar Icon” will display a nice mini forecast. Conclusion While WeatherBar may not be for everyone it does provide a nice easy way to monitor the weather from your “Taskbar” without taking up a lot of room.

• Trying to use stencils in 2D while retaining layer depth

  - by Steve

  This is a screen of what's going on just so you can get a frame of reference. http://i935.photobucket.com/albums/ad199/fobwashed/tilefloors.png The problem I'm running into is that my game is slowing down due to the amount of texture swapping I'm doing during my draw call. Since walls, characters, floors, and all objects are on their respective sprite sheet containing those types, per tile draw, the loaded texture is swapping no less than 3 to 5+ times as it cycles and draws the sprites in order to layer properly. Now, I've tried throwing all common objects together into their respective lists, and then using layerDepth drawing them that way which makes things a lot better, but the new problem I'm running into has to do with the way my doors/windows are drawn on walls. Namely, I was using stencils to clear out a block on the walls that are drawn in the shape of the door/window so that when the wall would draw, it would have a door/window sized hole in it. This is the way my draw was set up for walls when I was going tile by tile rather than grouped up common objects. first it would check to see if a door/window was on this wall. If not, it'd skip all the steps and just draw normally. Otherwise end the current spriteBatch Clear the buffers with a transparent color to preserve what was already drawn start a new spritebatch with stencil settings draw the door area end the spriteBatch start a new spritebatch that takes into account the previously set stencil draw the wall which will now be drawn with a hole in it end that spritebatch start a new spritebatch with the normal settings to continue drawing tiles In the tile by tile draw, clearing the depth/stencil buffers didn't matter since I wasn't using any layerDepth to organize what draws on top of what. Now that I'm drawing from lists of common objects rather than tile by tile, it has sped up my draw call considerably but I can't seem to figure out a way to keep the stencil system to mask out the area a door or window will be drawn into a wall. The root of the problem is that when I end a spriteBatch to change the DepthStencilState, it flattens the current RenderTarget and there is no longer any depth sorting for anything drawn further down the line. This means walls always get drawn on top of everything regardless of depth or positioning in the game world and even on top of each other as the stencil has to happen once for every wall that has a door or window. Does anyone know of a way to get around this? To boil it down, I need a way to draw having things sorted by layer depth while also being able to stencil/mask out portions of specific sprites.

• Play Framework Plugin for NetBeans IDE

  - by Geertjan

  The start of minimal support for the Play Framework in NetBeans IDE 7.3 Beta would constitute (1) recognizing Play projects, (2) an action to run a Play project, and (3) classpath support. Well, most of that I've created already, as can be seen, e.g., below you can see logical views in the Projects window for Play projects (i.e., I can open all the samples that come with the Play distribution). Right-clicking a Play project lets you run it and, if the embedded browser is selected in the Options window, you can see the result in the IDE. Make a change to your code and refresh the browser, which immediately shows you your changes: What needs to be done, among other things: A wizard for creating new Play projects, i.e., it would use the Play command line to create the application and then open it in the IDE. Integration of everything available on the Play command line. Maybe the logical view, i.e., what is shown in the Projects window, should be changed. Right now, only the folders "app" and "test" are shown there, with everything else accessible in the Files window, as can be seen in the screenshot above. More work on the classpath, i.e., I've hardcoded a few things just to get things to work correctly. Options window extension to register the Play executable, instead of the current hardcoded solution. Scala integrations, i.e., investigate if/how the NetBeans Scala plugin is helpful and, if not, create different/additional solutions. E.g., the HTML templates are partly in Scala, i.e., need to embed Scala support into HTML. Hyperlinking in the "routes" file, as well as special support for the "application.conf" file. Anyone interested, especially if you're a Play fan (a "playboy"?), in joining me in working on this NetBeans plugin? I'll be uploading the sources to a java.net repository soon. It will be here, once it has been made publicly accessible: http://java.net/projects/nbplay/sources/nbplay Kind of cool detail is that the NetBeans plugin is based on Maven, which means that you could use any Maven-supporting IDE to work on this plugin.

• Drawing a line using openGL does not work

  - by vikasm

  I am a beginner in OpenGL and tried to write my first program to draw some points and a line. I can see that the window opens with white background but no line is drawn. I was expecting to see red colored (because glColor3f(1.0, 0.0, 0.0);) dots (pixels) and line. But nothing is seen. Here is my code. void init2D(float r, float g, float b) { glClearColor(r,g,b,0.0); glMatrixMode(GL_PROJECTION); gluOrtho2D(0.0, 200.0, 0.0, 150.0); } void display() { glClear(GL_COLOR_BUFFER_BIT); glColor3f(1.0, 0.0, 0.0); glBegin(GL_POINTS); for(int i = 0; i < 10; i++) { glVertex2i(10+5*i, 110); } glEnd(); //draw a line glBegin(GL_LINES); glVertex2i(10,10); glVertex2i(100,100); glEnd(); glFlush(); } int main(int argc, char** argv) { //Initialize Glut glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); init2D(0.0, 0.0, 0.0); glutDisplayFunc(display); glutMainLoop(); } I wanted to verify that the glcontext was opening properly and used this code: int main(int argc, char **argv) { glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); char *GL_version=(char *)glGetString(GL_VERSION); puts(GL_version); char *GL_vendor=(char *)glGetString(GL_VENDOR); puts(GL_vendor); char *GL_renderer=(char *)glGetString(GL_RENDERER); puts(GL_renderer); getchar(); return 0; } And the ouput I got was: 3.1.0 - Build 8.15.10.2345 Intel Intel(R) HD Graphics Family Can someone point out what I am doing wrong ?

• trouble running smooth animation in thread only when using key listener

  - by heysuse renard

  first time using a forum for coding help so sorry if i post this all wrong. i have more than a few classes i don't think screenManger or core holds the problem but i included them just incase. i got most of this code working through a set of tutorials. but a certain point started trying to do more on my own. i want to play the animation only when i'm moving my sprite. in my KeyTest class i am using threads to run the animation it used to work (poorly) but now not at all pluss it really gunks up my computer. i think it's because of the thread. im new to threads so i'm not to sure if i should even be using one in this situation or if its dangerous for my computer. the animation worked smoothly when i had the sprite bouce around the screen forever. the animation loop played with out stopping. i think the main problem is between the animationThread, Sprite, and keyTest classes, but itcould be more indepth. if someone could point me in the right direction for making the animation run smoothly when i push down a key and stop runing when i let off it would be greatly apriciated. i already looked at this Java a moving animation (sprite) obviously we were doing the same tutorial. but i feel my problem is slightly different. p.s. sorry for the typos. import java.awt.*;

• Mac - Flash file not loaded in independent flash player

  - by Mugdha

  Hi, I am working on an independent application to play flash files on Mac. I have already done the same for Linux, and it works flawlessly but on mac for some reason flash is not drawing to my window. It is not throwing any kind of error too. I am using Flash player 10, that would mean that I am using the Core Graphics drawing model. I am able to send mouse events to flash and wrote a sample plugin to check if there was a problem in the context that I was sending, but my sample plugin draws properly to the window. I am getting a call for NPN_InvalidateRect twice and as a response I send an update Event back to flash. I drew a dummy rectangle to check that my context is correct. I have flipped the context to make the origin as top left corner. On doing right click on the debug version of the flash player it shows the following message: "Movie not loaded..." Can anyone give me any idea why is the content not being drawn? I would really appreciate the help, as I have been struggling with it for more than a month now. Here is a small log of the interaction that I have with flash: NPN_UserAgent Called NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPN_GetValue Called with variable NPNVSupportsWindowless; return true NPN_SetValue Called for Variable - NPPVpluginTransparentBool; return true NPN_GetValue Called with variable NPNVsupportsCoreGraphicsBool; return true NPN_SetValue Called for Variable - NPNVpluginDrawingModel NPP_SetWindow (CoreGraphics): 0, window=0xebaa90, context=0xe4c930, window.x:0 window.y:22 window.width:480 window.height:270 NPP_HandleEvent(activateEvent) accepted:0 isActive: 1 NPP_HandleEvent(updateEvt) accepted: 1 NPN_UserAgent Called NPN_GetURLNotify Called with URL - javascript:top.location+"flashplugin_unique" NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPP_NewStream URL=/Users/mjain/Desktop/clock.swf MIME=application/x-shockwave-flash error=0 NPP_WriteReady responseURL=/Users/mjain/Desktop/clock.swf bytes=268435455 NPN_InvalidateRect Called NPP_Write responseURL=/Users/mjain/Desktop/clock.swf bytes=9925 total-delivered=9925/9925 NPP_WriteReady responseURL=/Users/mjain/Desktop/clock.swf bytes=268435455 NPP_DestroyStream responseURL=/Users/mjain/Desktop/clock.swf error=0 NPP_HandleEvent(updateEvt) accepted: 1 NPN_InvalidateRect Called NPP_HandleEvent(updateEvt) accepted: 1 NPP_NewStream URL=javascript:top.location+"flashplugin_unique" MIME=text/plain error=0 NPP_WriteReady responseURL=javascript:top.location+"flashplugin_unique" bytes=16000 NPN_UserAgent Called NPP_Write responseURL=javascript:top.location+"flashplugin_unique" bytes=52 total-delivered=52/52 NPP_WriteReady responseURL=javascript:top.location+"flashplugin_unique" bytes=16000 NPP_DestroyStream responseURL=javascript:top.location+"flashplugin_unique" error=0 NPP_URLNotify responseURL=javascript:top.location+"flashplugin_unique" reason=0 Thanks Mugdha.

• jQuery load Google Visualization API with AJAX

  - by Curro

  Hello. There is an issue that I cannot solve, I've been looking a lot in the internet but found nothing. I have this JavaScript that is used to do an Ajax request by PHP. When the request is done, it calls a function that uses the Google Visualization API to draw an annotatedtimeline to present the data. The script works great without AJAX, if I do everything inline it works great, but when I try to do it with AJAX it doesn't work!!! The error that I get is in the declaration of the "data" DataTable, in the Google Chrome Developer Tools I get a Uncaught TypeError: Cannot read property 'DataTable' of undefined. When the script gets to the error, everything on the page is cleared, it just shows a blank page. So I don't know how to make it work. Please help Thanks in advance $(document).ready(function(){ // Get TIER1Tickets $("#divTendency").addClass("loading"); $.ajax({ type: "POST", url: "getTIER1Tickets.php", data: "", success: function(html){ // Succesful, load visualization API and send data google.load('visualization', '1', {'packages': ['annotatedtimeline']}); google.setOnLoadCallback(drawData(html)); } }); }); function drawData(response){ $("#divTendency").removeClass("loading"); // Data comes from PHP like: <CSV ticket count for each day>*<CSV dates for ticket counts>*<total number of days counted> // So it has to be split first by * then by , var dataArray = response.split("*"); var dataTickets = dataArray[0]; var dataDates = dataArray[1]; var dataCount = dataArray[2]; // The comma separation now splits the ticket counts and the dates var dataTicketArray = dataTickets.split(","); var dataDatesArray = dataDates.split(","); // Visualization data var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'Tickets'); data.addRows(dataCount); var dateSplit = new Array(); for(var i = 0 ; i < dataCount ; i++){ // Separating the data because must be entered as "new Date(YYYY,M,D)" dateSplit = dataDatesArray[i].split("-"); data.setValue(i, 0, new Date(dateSplit[2],dateSplit[1],dateSplit[0])); data.setValue(i, 1, parseInt(dataTicketArray[i])); } var annotatedtimeline = new google.visualization.AnnotatedTimeLine(document.getElementById('divTendency')); annotatedtimeline.draw(data, {displayAnnotations: true}); }

• Why is jQuery .load() firing twice?

  - by LeslieOA

  Hello S-O. I'm using jQuery 1.4 with jQuery History and trying to figure out why Firebug/Web Inspector are showing 2 XHR GET requests on each page load (double that amount when visiting my sites homepage (/ or /#). e.g. Visit this (or any) page with Firebug enabled. Here's the edited/relevant code (see full source): - $(document).ready(function() { $('body').delegate('a', 'click', function(e) { var hash = this.href; if (hash.indexOf(window.location.hostname) > 0) { /* Internal */ hash = hash.substr((window.location.protocol+'//'+window.location.host+'/').length); $.historyLoad(hash); return false; } else if (hash.indexOf(window.location.hostname) == -1) { /* External */ window.open(hash); return false; } else { /* Nothing to do */ } }); $.historyInit(function(hash) { $('#loading').remove(); $('#container').append('<span id="loading">Loading...</span>'); $('#ajax').animate({height: 'hide'}, 'fast', 'swing', function() { $('#page').empty(); $('#loading').fadeIn('fast'); if (hash == '') { /* Index */ $('#ajax').load('/ #ajax','', function() { ajaxLoad(); }); } else { $('#ajax').load(hash + ' #ajax', '', function(responseText, textStatus, XMLHttpRequest) { switch (XMLHttpRequest.status) { case 200: ajaxLoad(); break; case 404: $('#ajax').load('/404 #ajax','', ajaxLoad); break; // Default 404 default: alert('We\'re experiencing technical difficulties.

• Inserting newlines into a GtkTextView widget (GTK+ programming)

  - by Mark Roberts

  I've got a button which when clicked copies and appends the text from a GtkEntry widget into a GtkTextView widget. (This code is a modified version of an example found in the "The Text View Widget" chapter of Foundations of GTK+ Development.) I'm looking to insert a newline character before the text which gets copied and appended, such that each line of text will be on its own line in the GtkTextView widget. How would I do this? I'm brand new to GTK+. Here's the code sample: #include <gtk/gtk.h> typedef struct { GtkWidget *entry, *textview; } Widgets; static void insert_text (GtkButton*, Widgets*); int main (int argc, char *argv[]) { GtkWidget *window, *scrolled_win, *hbox, *vbox, *insert; Widgets *w = g_slice_new (Widgets); gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (GTK_WINDOW (window), "Text Iterators"); gtk_container_set_border_width (GTK_CONTAINER (window), 10); gtk_widget_set_size_request (window, -1, 200); w->textview = gtk_text_view_new (); w->entry = gtk_entry_new (); insert = gtk_button_new_with_label ("Insert Text"); g_signal_connect (G_OBJECT (insert), "clicked", G_CALLBACK (insert_text), (gpointer) w); scrolled_win = gtk_scrolled_window_new (NULL, NULL); gtk_container_add (GTK_CONTAINER (scrolled_win), w->textview); hbox = gtk_hbox_new (FALSE, 5); gtk_box_pack_start_defaults (GTK_BOX (hbox), w->entry); gtk_box_pack_start_defaults (GTK_BOX (hbox), insert); vbox = gtk_vbox_new (FALSE, 5); gtk_box_pack_start (GTK_BOX (vbox), scrolled_win, TRUE, TRUE, 0); gtk_box_pack_start (GTK_BOX (vbox), hbox, FALSE, TRUE, 0); gtk_container_add (GTK_CONTAINER (window), vbox); gtk_widget_show_all (window); gtk_main(); return 0; } /* Insert the text from the GtkEntry into the GtkTextView. */ static void insert_text (GtkButton *button, Widgets *w) { GtkTextBuffer *buffer; GtkTextMark *mark; GtkTextIter iter; const gchar *text; buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (w->textview)); text = gtk_entry_get_text (GTK_ENTRY (w->entry)); mark = gtk_text_buffer_get_insert (buffer); gtk_text_buffer_get_iter_at_mark (buffer, &iter, mark); gtk_text_buffer_insert (buffer, &iter, text, -1); } You can compile this command (assuming the file is named file.c): gcc file.c -o file `pkg-config --cflags --libs gtk+-2.0` Thanks everybody!

• Multi-Threading Question Concerning WPF

  - by Andrew

  Hello, I'm a newbie to threading, and I don't really know how to code a particular task. I would like to handle a mouse click event on a window that will kick off a while loop in a seperate thread. This thread, which is distinct from the UI thread, should call a function in the while loop which updates a label on the window being serviced by the UI thread. The while loop should stop running when the left mouse button is no longer being pressed. All the loop does is increment a counter, and then repeatedly call the function which displays the updated value in the window. The code for the window and all of the threading is given below (I keep getting some error about STA threading, but don't know where to put the attribute). Also, I'm hoping to use this solution, if it ever works, in another project that makes asynchronous calls elsewhere to a service via wcf, so I was hoping not to make any application-wide special configurations, since I'm really new to multi-threading and am quite worried about breaking other code in a larger program... Here's what I have: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication2" Name="MyMainWindow" Title="MainWindow" Width="200" Height="150" PreviewMouseLeftButtonDown="MyMainWindow_PreviewMouseLeftButtonDown"> <Label Height="28" Name="CounterLbl" /> </Window> And here's the code-behind: using System.Windows; using System.Windows.Input; using System.Threading; namespace WpfApplication2 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { private int counter = 0; public MainWindow() { InitializeComponent(); } private delegate void EmptyDelegate(); private void MyMainWindow_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { Thread counterThread = new Thread(new ThreadStart(MyThread)); counterThread.Start(); } private void MyThread() { while (Mouse.LeftButton == MouseButtonState.Pressed) { counter++; Dispatcher.Invoke(new EmptyDelegate(UpdateLabelContents), null); } } private void UpdateLabelContents() { CounterLbl.Content = counter.ToString(); } } } Anyways, multi-threading is really new to me, and I don't have any experience implementing it, so any thoughts or suggestions are welcome! Thanks, Andrew

• Accessing contents of NativeWindow in a HTML AIR application?

  - by Dan Scotton

  I'm currently building a HTML/JS AIR application. The application needs to display to the user a different 'window' - dependant on whether this is the first time they've launched the application or not. This part is actually fine and I have the code below to do that: if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with the .air // do first time stuff var windowOptions = new air.NativeWindowInitOptions(); windowOptions.systemChrome = 'none'; windowOptions.type = 'lightweight'; windowOptions.transparent = 'true'; windowOptions.resizable = 'false'; var windowBounds = new air.Rectangle(300, 300, 596, 490); var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions, true, windowBounds); newHtmlLoader.load(new air.URLRequest('cover.html')); } else { // display default window // just set nativeWindow.visible = true (loaded from application.xml) } However, what I want to be able to do is manipulate the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc. the NativeWindow, but I simply want access to the NativeWindow's HTML content. For example, how would I add a new paragraph to that page? I've tried the following: newHtmlLoader.window.opener = window; var doc = newHtmlLoader.window.opener.document.documentElement; Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement]. Hmm, seems promising right? I then go on to try: var p = document.createElement('p'); var t = document.createTextNode('Insert Me'); p.appendChild(t); doc.appendChild(p); ...but nothing gets inserted. I've also tried the following replacements for doc: var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement] var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3 ...as well as the following with jQuery: $(doc).append('<p>Insert Me</p>'); // again, nothing So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.

• Infinite loop when adding a row to a list in a class in python3

  - by Margaret

  I have a script which contains two classes. (I'm obviously deleting a lot of stuff that I don't believe is relevant to the error I'm dealing with.) The eventual task is to create a decision tree, as I mentioned in this question. Unfortunately, I'm getting an infinite loop, and I'm having difficulty identifying why. I've identified the line of code that's going haywire, but I would have thought the iterator and the list I'm adding to would be different objects. Is there some side effect of list's .append functionality that I'm not aware of? Or am I making some other blindingly obvious mistake? class Dataset: individuals = [] #Becomes a list of dictionaries, in which each dictionary is a row from the CSV with the headers as keys def field_set(self): #Returns a list of the fields in individuals[] that can be used to split the data (i.e. have more than one value amongst the individuals def classified(self, predicted_value): #Returns True if all the individuals have the same value for predicted_value def fields_exhausted(self, predicted_value): #Returns True if all the individuals are identical except for predicted_value def lowest_entropy_value(self, predicted_value): #Returns the field that will reduce <a href="http://en.wikipedia.org/wiki/Entropy_%28information_theory%29">entropy</a> the most def __init__(self, individuals=[]): and class Node: ds = Dataset() #The data that is associated with this Node links = [] #List of Nodes, the offspring Nodes of this node level = 0 #Tree depth of this Node split_value = '' #Field used to split out this Node from the parent node node_value = '' #Value used to split out this Node from the parent Node def split_dataset(self, split_value): fields = [] #List of options for split_value amongst the individuals datasets = {} #Dictionary of Datasets, each one with a value from fields[] as its key for field in self.ds.field_set()[split_value]: #Populates the keys of fields[] fields.append(field) datasets[field] = Dataset() for i in self.ds.individuals: #Adds individuals to the datasets.dataset that matches their result for split_value datasets[i[split_value]].individuals.append(i) #<---Causes an infinite loop on the second hit for field in fields: #Creates subnodes from each of the datasets.Dataset options self.add_subnode(datasets[field],split_value,field) def add_subnode(self, dataset, split_value='', node_value=''): def __init__(self, level, dataset=Dataset()): My initialisation code is currently: if __name__ == '__main__': filename = (sys.argv[1]) #Takes in a CSV file predicted_value = "# class" #Identifies the field from the CSV file that should be predicted base_dataset = parse_csv(filename) #Turns the CSV file into a list of lists parsed_dataset = individual_list(base_dataset) #Turns the list of lists into a list of dictionaries root = Node(0, Dataset(parsed_dataset)) #Creates a root node, passing it the full dataset root.split_dataset(root.ds.lowest_entropy_value(predicted_value)) #Performs the first split, creating multiple subnodes n = root.links[0] n.split_dataset(n.ds.lowest_entropy_value(predicted_value)) #Attempts to split the first subnode.

• Convert string from getline into a number

  - by haskellguy

  I am trying to create a 2D array with vectors. I have a file that has for each line a set of numbers. So what I did I implemented a split function that every time I have a new number (separated by \t) it splits that and add it to the vector vector<double> &split(const string &s, char delim, vector<double> &elems) { stringstream ss(s); string item; while (getline(ss, item, delim)) { cout << item << endl; double number = atof(item.c_str()); cout << number; elems.push_back(number); } return elems; } vector<double> split(const string &s, char delim) { vector<double> elems; split(s, delim, elems); return elems; } After that I simply iterate through it. int main() { ifstream file("./data/file.txt"); string row; vector< vector<double> > matrix; int line_count = -1; while (getline(file, row)) { line_count++; if (line_count <= 4) continue; vector<double> cols = split(row, '\t'); matrix.push_back(cols); } ... } Now my issues is in this bit here: while (getline(ss, item, delim)) { cout << item << endl; double number = atof(item.c_str()); cout << number; Where item.c_str() is converted to a 0. Shouldn't that be still a string having the same value as item? It works on a separate example if I do straight from string to c_string, but when I use this getline I end up in this error situation, hints?

• How to compare DateTime Objects while looping through a list?

  - by Taniq

  I'm trying to loop through a list (csv) containing two fields; a name and a date. There are various duplicated names and various dates in the list. I'm trying to deduce for each name in the list, where there are multiple instances of the same name, which corresponding date is the latest. I realise, from looking at another answer, that I need to use the DateTime.Compare method which is fine, but my problem is working out which date is later. Once I know this I need to produce a file with unique names and the latest date relating to it. This is my first question which makes me a newbie. EDIT: Initially I thought it would be 'ok' to set the LatestDate object to a date that wouldn't show up in my file, therefore making any later dates in the file the LatestDate. Here's my coding so far: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace flybe_overwriter { class Program { static DateTime currentDate; static DateTime latestDate = new DateTime(1000,1,1); static HashSet<string> uniqueNames = new HashSet<string>(); static string indexpath = @"e:\flybe test\indexing.csv"; static string[] indexlist = File.ReadAllLines(indexpath); static StreamWriter outputfile = new StreamWriter(@"e:\flybe test\match.csv"); static void Main(string[] args) { foreach (string entry in indexlist) { uniqueNames.Add(entry.Split(',')[0]); } HashSet<string>.Enumerator fenum = new HashSet<string>.Enumerator(); fenum = uniqueNames.GetEnumerator(); while (fenum.MoveNext()) { string currentName = fenum.Current; foreach (string line in indexlist) { currentDate = new DateTime(Convert.ToInt32(line.Split(',')[1].Substring(4, 4)), Convert.ToInt32(line.Split(',')[1].Substring(2, 2)), Convert.ToInt32(line.Split(',')[1].Substring(0, 2))); if (currentName == line.Split(',')[0]) { if(DateTime.Compare(latestDate.Date, currentDate.Date) < 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is earlier than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) > 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is later than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) == 0) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is the same as " + currentDate.ToShortDateString()); } } } } } } } Any help appreciated. Thanks.

• Windows Keys Extender – tool for XP/Vista users to using hotkeys Win+[Left|Right|Up|Down]

  - by outcoldman

  In Windows 7, I really liked an opportunity to change the position of the windows by pressing hotkeys Win + (Left | Right | Up | Bottom): Win + Left - window attached to the left side Win + Right - window attached to the right side Win + Up - window is maximized Win + Bottom - window in the normal state I’m talking about this: This is really useful hotkeys and really comfortable work with windows. But not all can use Windows 7 right now. When Windows7 was in beta and RC states I really wanted to use this features right now in current Windows version (I had Vista). So I spent my time and wrote this tool. In addition, the tool has functional which can change position of windows (It is useful for laptops, you can move windows with hotkeys). And of course this tool can move windows between monitors. Hot keys can be customized. Interface in English. Now I don’t want to add new functionality, because now I’m using Windows 7 with all functions that this tool have. I wrote this tool on C# with .NET 3.5. You can use this source code for knowing how to work with hotkeys with C#. At first I placed source code on Google Code and then placed it on CodePlex too. So you can download it from one of them. I would be glad if someone will use it. :)
