  • How to Print in VS10, Printing gives unhandled exception. Access Denied

    Im newish to coding, currently on a Windows Forms App using CLI in VS10 Everything seems to work, my document shows fine in the Preview dialog but then crash's.

In case this is all wrong. what is the minimum requirements in code for a print job? Is there an easier way?

  • Rendering a Long Document on iPad

    - by benjismith
    I'm implementing a document viewer with highlighting/annotation capabilities for a custom document format on iPad. The documents are kind of long (100 to 200 pages, if printed on paper) and I've had a hard time finding the right approach. Here are the requirments: 1) Basic rich-text styling: control of left/right margins. Control of font name, size, foreground/background color, and line spacing. Bold, italics, underline, etc. 2) Selection and highlighting of arbitrary text regions (not limited to paragraph boundaries, like in Safari/UIWebView). 3) Customization of the Cut/Copy/Paste popup (what is that thing called anyhow? UIActionBar?) This is one of the essential requirements of the app. My first implementation was based on UIWebView. I just rendered the document as HTML with CSS for text styling. But I couldn't get the kind of text selection behavior I wanted (across paragraph boundaries) and the UIActionBar can't be customized from within UIWebView. So I started working on a javascript approach, faking the device text-selection behavior using JQuery to trap touch events and dynamically modifying the DOM to change the background color of selected regions of text. I built a fake UIActionBar control as a hidden DIV, positioning it and unhiding it whenever there was an active selection region. Not too shabby. The main problem is that it's SLOOOOOOOW. Scrolling through the document is nice and quick, but dynamically changing the DOM is not very snappy. Plus, I couldn't figure out how to recreate the magnifier loupe, so my fake text-selection GUI doesn't look quite the same as the native implementation. Also, I haven't yet implemented the communication bridge between the javascript layer and the objective-c layer (where the rest of the app lives), but it was shaping up to be a huge hassle. So I've been looking at CoreText, but there are precious few examples on the web. I spent a little time with this simple little demo: http://github.com/jonasschnelli/I7CoreTextExample/ It shows how to use CoreText to draw an NSAttributedText string into a UIView. But it has its own problems: It doesn't implement text-selection behavior, and it doesn't present a UIActionBar, so I don't have any idea how to make that happen. And, more importantly, it tries to draw the entire document all at once, with significant performance degradations for long documents. My documents can have thousands of paragraphs, and less than 1% of the document is ever on screen at a time. On the plus side, these documents already contain precise formatting information. I know the exact page-position of every line of text, so I don't need a layout engine. Does anyone know how to implement this sort of view using CoreText? I understand that a full-fledged implementation is overkill for a question like this, but I'm looking for a good CoreText example with a few basic requirements: 1) Precise layout & formatting control (using the formatting metrics and text styles I've already calculated). 2) Arbitrary selection of text. 3) Customization of the UIActionBar. 4) Efficient recycling of resources for off-screen objects. I'd be happy to implement my own recycling when text elements scroll off-screen, but wouldn't that require re-implementing UIScrollView? I'm brand-new to iPhone development, and still getting used to Objective-C, but I've been working in other languages (Java, C#, flex/actionscript, etc) for more than ten years, so I feel confident in my ability to get the work done, if only I had a better feel for the iPhone SDK and the common coding patterns for stuff like this. Is it just me, or does the SDK documentation really suck? Anyhow, thanks for your help!

  • How come my form input sometimes moves when I refresh the page?

    - by samoz
    On a page that I'm designing I have a form with one input of type text. Normally, this form and input render properly in my browser, Chrome, but occasionally, it renders about 20 pixels to the left of where it is supposed to be. When I refresh the page, it goes back to the original, correct place. I have only tested in Chrome so far, so this isn't a cross-browser issue (it happens in the same browser). Is there anything wrong with my code below? Here's my HTML code: <!DOCTYPE htmls> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="style.css" type="text/css" /> <title>Test Site</title> </head> <body > <div id="supercontainer" class="style1"> <img class="floater" src="top.jpg" alt="Top" /> <img class="floater" src="left.jpg" alt="Left" /> <div id="content"> <p id="theText"> Welcome. Please type a username. </p> <form id="prompt"> <div><input type="text" name="promptLine" autocomplete="off" id="promptLine" onkeypress="return submitenter(event);" value="% " /></div> </form> </div> <img class="floater" src="right.jpg" alt="Right" /> <img class="floater" src="bottom.jpg" alt="Bottom" /> </div> Here's my CSS code: #supercontainer { margin: 0 auto; width: 900px; display: block; } img.floater { display: inline; float: left; } #content { background-color:black; display: inline; float: left; padding-left:5px; padding-right:5px; min-height:458px; max-height:458px; min-width: 803px; max-width: 803px; color: lime; } #theText { text-align:left; margin-bottom:0; margin-top:0; line-height: 0.3; font-family:"Courier New", Courier, monospace; } #prompt { position: fixed; top: 470px; } #promptLine { width: 100%; background-color: black; color: lime; border: none; outline:none; }

  • Scaling an image using the mouse in a WinForms application?

    - by Gaax
    I'm trying to use the position of the mouse to calculate the scaling factor for scaling an image. Basically, the further you get away from the center of the image, the bigger it gets; and the closer to the center you get, the smaller it gets. I have some code so far but it's acting really strange and I have absolutely no more ideas. First I'll let you know, one thing I was trying to do is average out 5 distances to get a more smooth resize animation. Here's my code: private void pictureBoxScale_MouseMove(object sender, MouseEventArgs e) { if (rotateScaleMode && isDraggingToScale) { // For Scaling int sourceWidth = pictureBox1.Image.Width; int sourceHeight = pictureBox1.Image.Height; float dCurrCent = 0; // distance between the current mouse pos and the center of the image float dPrevCent = 0; // distance between the previous mouse pos and the center of the image System.Drawing.Point imgCenter = new System.Drawing.Point(); imgCenter.X = pictureBox1.Location.X + (sourceWidth / 2); imgCenter.Y = pictureBox1.Location.Y + (sourceHeight / 2); // Calculating the distance between the current mouse location and the center of the image dCurrCent = (float)Math.Sqrt(Math.Pow(e.X - imgCenter.X, 2) + Math.Pow(e.Y - imgCenter.Y, 2)); // Calculating the distance between the previous mouse location and the center of the image dPrevCent = (float)Math.Sqrt(Math.Pow(prevMouseLoc.X - imgCenter.X, 2) + Math.Pow(prevMouseLoc.Y - imgCenter.Y, 2)); if (smoothScaleCount < 5) { dCurrCentSmooth[smoothScaleCount] = dCurrCent; dPrevCentSmooth[smoothScaleCount] = dPrevCent; } if (smoothScaleCount == 4) { float currCentSum = 0; float prevCentSum = 0; for (int i = 0; i < 4; i++) { currCentSum += dCurrCentSmooth[i]; } for (int i = 0; i < 4; i++) { prevCentSum += dPrevCentSmooth[i]; } float scaleAvg = (currCentSum / 5) / (prevCentSum / 5); int destWidth = (int)(sourceWidth * scaleAvg); int destHeight = (int)(sourceHeight * scaleAvg); // If statement is for limiting the size of the image if (destWidth > (currentRotatedImage.Width / 2) && destWidth < (currentRotatedImage.Width * 3) && destHeight > (currentRotatedImage.Height / 2) && destWidth < (currentRotatedImage.Width * 3)) { AForge.Imaging.Filters.ResizeBilinear resizeFilter = new AForge.Imaging.Filters.ResizeBilinear(destWidth, destHeight); pictureBox1.Image = resizeFilter.Apply((Bitmap)currentRotatedImage); pictureBox1.Size = pictureBox1.Image.Size; pictureBox1.Refresh(); } smoothScaleCount = -1; } prevMouseLoc = e.Location; currentScaledImage = pictureBox1.Image; smoothScaleCount++; } }

  • Organising XML results as cells in container (AS3)

    - by PJ Palomaki
    Hi, I'm having some problems figuring out how to organise data pulled off XML in cells within a container. I'm sure this should be a basic thing in AS3, but my head's fried.. can anyone help? Basically an array if fed to callThumbs() which iterates through it and compares the entries with preloaded XML _my_images. If match is found, it's sent to processXML which loads all relevant info and loads a .jpg thumbnail. All this is then fed to createCell which creates a specific cell with position values depending on x_counter and y_counter values (4 cells in a row) and adds the cell into a container _container_mc. The Problem: This all works fine and looks fine, the problem is that the cells within the container do not display in descending order. They are in random order, probably because some of the .jpg's takes longer to load etc. How do I easily organise the cells within the container in descending order by the XML .id value? Or how do I tell Flash to wait till the thumbnail and data is loaded and the cell created and added? Thanks guys, would really appreciate all the help! PJ //Flash (AS3) function callThumbs(_my_results:Array):void { // selector = 1 for specific items, 2 for search items var _thumb_url:XML; for (var r:Number=0; r < _my_results.length; r++) { // iterate through results vector, compare with _my_images XML .id for (var i:Number=0; i < _my_images.length(); i++) { if (_my_images[i][email protected]() == _my_results[r]) { _thumb_url=_my_images[i]; processXML(_thumb_url, i); } } } } // End callThumbs function processXML(imageXML:XML, num:Number) { // Processes XML data and loads .jpg thumbnail var _thumb_loader=new Loader(); _thumb_loader.load(new URLRequest("thumbs/thumb_sm/" + imageXML.@id + "_st.jpg")); _thumb_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,thumbLoaded); _thumb_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, urlNotFound); var id:XMLList = new XMLList; id = imageXML.@id; var description:XMLList = new XMLList; description = imageXML.@description; function urlNotFound(event:IOErrorEvent):void { trace("The image URL '" + String(imageXML.@id) + "' was not found."); } function thumbLoaded(e:Event):void { var imageLoader:Loader = Loader(e.target.loader); var bm:Bitmap = Bitmap(imageLoader.content); createCell(bm, id, description, num); adjustFooterBar(); // Adjust bottom footer } } // End processXML private function createCell(_image:Bitmap, _id, _description:String, _position):void { // Creates a cell with data, add to container var _cell_mc = new CellTitle(); _cell_mc.initCell(_image, _id, _description, _position, x_counter, y_counter); if (x_counter+1 < 4) { x_counter++; } else { x_counter = 0; y_counter++; } _container_mc.addChild(_cell_mc); // movieclip container } // End createCell

  • Search Form in Responsive Design - Remove Search button on Mobile

    - by Kevin
    I'm working with a search box in the header of a responsive website. On desktop/tablet widths, there's a search input field and a styled 'search' button to the right. You can type in a search term and either click 'SEARCH' button or just hit enter on the keyboard with the same result. When you scale down to mobile widths, the search input field fills the width of the screen. The submit button falls below it. On a desktop, clicking the button or hitting enter activate the search. On an actual iphone phone, you can hit the 'SEARCH' button, but the native mobile keyboard that rises from the bottom of the screen has a search button where the enter/return key would normally be. It seems to know I'm in a form and the keyboard automatically gives me the option to kick off the search by basically hitting the ENTER key location....but it says SEARCH. So far so good. I figure I don't need the button in the header on mobile since it's already in the keyboard. Therefore, I'll hide the button on mobile widths and everything will be tighter and look better. So I added this to my CSS to hide it in mobile: #search-button {display: none;} But now the search doesn't work at all. On mobile, I don't get the option in the keyboard that showed up before and if I just hit enter, it doesn't work at all. On desktop at mobile width, hitting enter also not longer works. So clearly by hiding the submit/search button, the phone no longer gave me the native option to run the search. In addition, on the desktop at mobile width, even hitting enter inside the search input box also fails to launch the the search. Here's my search box: <form id="search-form" method="get" accept-charset="UTF-8, utf-8" action="search.php"> <fieldset> <div id="search-wrapper"> <label id="search-label" for="search">Item:</label> <input id="search" class="placeholder-color" name="item" type="text" placeholder="Item Number or Description" /> <button id="search-button" title="Go" type="submit"><span class="search-icon"></span></button> </div> </fieldset> </form> Here's what my CSS looks like: #search-wrapper { float: left; display: inline-block; position: relative; white-space: nowrap; } #search-button { display: inline-block; cursor: pointer; vertical-align: top; height: 30px; width: 40px; } @media only screen and (max-width: 639px) { #search-wrapper { display: block; margin-bottom: 7px; } #search-button { /* this didn't work....it hid the button but the search failed to load */ display: none;*/ } } So.....how can I hide this submit button when I'm on a mobile screen, but still let the search run from the mobile keyboard or just run by hitting enter when in the search input box. I was sure that putting display:none on the search button at mobile width would do the trick, but apparently not. Thanks...

  • Clear float issue

    - by Jason
    I have a page with the standard navigation bar on the left and the content area taking up the rest of the horizontal area to its side. For modern browsers I am using table-row and table-cell values for the display attribute. However, for IE7 I included a conditional stylesheet that tries to float the nav bar. This works fine except when the content area itself has floated elements and I try to use clear. My goal is to displayed the clear element right after the content area floats but instead it gets shoved down below the nav area. The following demo code shows this issue. My goal is to get the table to display right below the "leftThing" and "rightThing" but instead there is a large gap between them and the table. <html> <head> <title>Float Test</title> <style type="text/css"> #body { background: #cecece; } #sidebar { background: #ababab; float: left; width: 200px; } #content { background: #efefef; margin-left: 215px; } #leftThing { background: #456789; float: left; width: 100px; } #rightThing { background: #654321; float: right; width: 100px; } table { clear: both; } </style> </head> <body> <div id="body"> <div id="sidebar"> <ul> <li>One</li> <li>Two</li> <li>Three</li> </ul> </div> <div id="content"> <div style="position: realtive;"> <div id="leftThing"> ABCDEF </div> <div id="rightThing"> WXYZ </div> <table> <thead> <th>One</th> <th>Two</th> </thead> <tr> <td>Jason</td> <td>45</td> </tr> <tr> <td>Mary</td> <td>41</td> </tr> </table> <p>Exerci ullamcorper consequat duis ipsum ut nostrud zzril, feugait feugiat duis dolor feugiat commodo, accumsan, duis illum eum molestie luptatum nisl iusto.

  • Source code versioning with comments (organizational practice) - leave or remove?

    - by ADTC
    Before you start admonishing me with "DON'T DO IT," "BAD PRACTICE!" and "Learn to use proper source code control", please hear me out first. I am fully aware that the practice of commenting out old code and leaving it there forever is very bad and I hate such practice myself. But here's the situation I'm in. A few months ago I joined a company as software developer. I had worked in the company for few months as an intern, about a year before joining recently. Our company uses source code version control (CVS) but not properly. Here's what happened both in my internship and my current permanent position. Each time I was assigned to work on a project (legacy, about 8-10 years old). Instead of creating a CVS account and letting me check out code and check in changes, a senior colleague exported the code from CVS, zipped it up and passed it to me. While this colleague checks in all changes in bulk every few weeks, our usual practice is to do fine-grained versioning in the actual source code itself (each file increments in versions independent from the rest). Whenever a change is made to a file, old code is commented out, new code entered below it, and this whole section is marked with a version number. Finally a note about the changes is placed at the top of the file in a section called Modification History. Finally the changed files are placed in a shared folder, ready and waiting for the bulk check-in. /* * Copyright notice blah blah * Some details about file (project name, file name etc) * Modification History: * Date Version Modified By Description * 2012-10-15 1.0 Joey Initial creation * 2012-10-22 1.1 Chandler Replaced old code with new code */ code .... //v1.1 start //old code new code //v1.1 end code .... Now the problem is this. In the project I'm working on, I needed to copy some new source code files from another project (new in the sense that they didn't exist in destination project before). These files have a lot of historical commented out code and comment-based versioning including usually long or very long Modification History section. Since the files are new to this project I decided to clean them up and remove unnecessary code including historical code, and start fresh at version 1.0. (I still have to continue the practice of comment-based versioning despite hating it. And don't ask why not start at version 0.1...) I have done similar something during my internship and no one said anything. My supervisor has seen the work a few times and didn't say I shouldn't do such clean-up (if at all it was noticed). But a same-level colleague saw this and said it's not recommended as it may cause downtime in the future and increase maintenance costs. An example is when changes are made in another project on the original files and these changes need to be propagated to this project. With code files drastically different, it could cause confusion to an employee doing the propagation. It makes sense to me, and is a valid point. I couldn't find any reason to do my clean-up other than the inconvenience of a ridiculously messy code. So, long story short: Given the practice in our company, should I not do such clean-up when copying new files from project to project? Is it better to make changes on the (copy of) original code with full history in comments? Or what justification can I give for doing the clean-up? PS to mods: Hope you allow this question some time even if for any reason you determine it to be unfit in SO. I apologize in advance if anything is inappropriate including tags.

Could anybody recommend an alternative method if it is bad? Thank-you.

  • How to get data from struts2 action with jQuery?

    - by Rafa Romero
    I have an Struts2 Web with GoogleMaps. I want to load a list of markers which are saved in a SQL DDBB. To do this, I tried with jQuery and Ajax. Here you are the code: loadMarkers.java public class loadMarkers extends ActionSupport implements ServletRequestAware,ServletResponseAware{ //Variables de sesion/cookie FunctionClass ses; protected HttpServletResponse servletResponse; protected HttpServletRequest servletRequest; private String userID=""; //Variables del marker private List<marker> markersList = new ArrayList<marker>(); public String execute() throws Exception{ FunctionClass friends = new FunctionClass(); //Leemos de la cookie for(Cookie c : servletRequest.getCookies()) { if (c.getName().equals("userID")) userID = (c.getValue()); } System.out.println("en el loadMarkers"); connectionBBDD con = new connectionBBDD(); markersList = con.loadMarkers(userID); return SUCCESS; } I want to use the markerList array in Javascript, to create the markers. This is the struts.xml file: <package name="jsonActions" namespace="/test" extends="json-default"> <action name="LoadMarkers" class="web.localizadroid.maps.loadMarkers"> <interceptor-ref name="basicStack"/> <result type="json"> <param name="root">markersList</param> </result> </action> </package> And here you are the Javascript (jQuery) code: function loadMarkersJ(){ alert("dentro"); $.ajax({ type : "post", url : "LoadMarkers", dataType: "json", success : function(data) { alert(data); var image = new google.maps.MarkerImage ('http://i53.tinypic.com/ettquh.png'); var jSon_Object = eval("(" + data + ")"); //For para analizar los datos (Json) obtenidos de la BBDD for (x = 0; x < jSon_Object.length; x++) { var markersArray = []; var myLatlng = new google.maps.LatLng(jSon_Object[x].lat, jSon_Object[x].lon); markerLoaded = new google.maps.Marker( { position : myLatlng, map : map, icon: image, title: "NOMBRE: " + jSon_Object[x].tarjetName + "\n" + "ANOTACIONES: " + jSon_Object[x].anotaciones + "\n" + "TIME: " + jSon_Object[x].time }); markersArray.push(markerLoaded); if (markersArray) { for (i in markersArray) { alert("entro en forColocaMarkers"); if (markersArray[i].getAnimation() != null) { markersArray[i].setAnimation(null); } else { markersArray[i].setAnimation(google.maps.Animation.BOUNCE); } markersArray[i].setMap(map); } } } } }); } From success : function(data) { to the end, is JavaScript code to create de markers, and this it's OK. The problem is whith ajax, because I don't get to obtain markerList Array by jSon data return...I think that the problem is in the url attribute from $.ajax...I tried loadMarkers.action and loadMarkers, but nothing happens. When I execute the web, only prints the alert alert("dentro"), the alert alert(data) never has been printed. I have forgotten to add the code where I call the Javascript function (loadMarkersJ). Here you are: <p><s:a action="LoadMarkers.action" namespace="/test" onclick="loadMarkersJ(this)">Cargar Marcadores S</s:a></p> Somebody can help me please?

  • Using GA in GUI

    - by AlexT
    Sorry if this isn't clear as I'm writing this on a mobile device and I'm trying to make it quick. I've written a basic Genetic Algorithm with a binary encoding (genes) that builds a fitness value and evolves through several iterations using tournament selection, mutation and crossover. As a basic command-line example it seems to work. The problem I've got is with applying a genetic algorithm within a GUI as I am writing a maze-solving program that uses the GA to find a method through a maze. How do I turn my random binary encoded genes and fitness function (add all the binary values together) into a method to control a bot around a maze? I have built a basic GUI in Java consisting of a maze of labels (like a grid) with the available routes being in blue and the walls being in black. To reiterate my GA performs well and contains what any typical GA would (fitness method, get and set population, selection, crossover, etc) but now I need to plug it into a GUI to get my maze running. What needs to go where in order to get a bot that can move in different directions depending on what the GA says? Rough pseudocode would be great if possible As requested, an Individual is built using a separate class (Indiv), with all the main work being done in a Pop class. When a new individual is instantiated an array of ints represent the genes of said individual, with the genes being picked at random from a number between 0 and 1. The fitness function merely adds together the value of these genes and in the Pop class handles selection, mutation and crossover of two selected individuals. There's not much else to it, the command line program just shows evolution over n generations with the total fitness improving over each iteration. EDIT: It's starting to make a bit more sense now, although there are a few things that are bugging me... As Adamski has suggested I want to create an "Agent" with the options shown below. The problem I have is where the random bit string comes into play here. The agent knows where the walls are and has it laid out in a 4 bit string (i.e. 0111), but how does this affect the random 32 bit string? (i.e. 10001011011001001010011011010101) If I have the following maze (x is the start place, 2 is the goal, 1 is the wall): x 1 1 1 1 0 0 1 0 0 1 0 0 0 2 If I turn left I'm facing the wrong way and the agent will move completely off the maze if it moves forward. I assume that the first generation of the string will be completely random and it will evolve as the fitness grows but I don't get how the string will work within a maze. So, to get this straight... The fitness is the result of when the agent is able to move and is by a wall. The genes are a string of 32 bits, split into 16 sets of 2 bits to show the available actions and for the robot to move the two bits need to be passed with four bits from the agent showings its position near the walls. If the move is to go past a wall the move isn't made and it is deemed invalid and if the move is made and if a new wall is found then the fitness goes up. Is that right?

  • jQuery hold form submit until "continue" button pressed

    - by Seán McCabe
    I am trying to submit a form, which I have had working, but have now modified it to include a modal jQuery UI box, so that it won't submit until the user presses "continue". I've had various problems with this, including getting the form to hold until that button is pressed, but I think I have found a solution to that, but implementing it, I am getting a SyntaxError which I can't find the source of. With the help of kevin B managed to find the answer was the form was submitting, but the returned JSON response wasn't quite formatted right. The response was that the form wasn't being submitted, so that problem is still occurring. So updated the code with the provided feedback, now need to find out why the form isnt submitting. I know its something to do with the 2nd function isnt recognising the submit button has been pressed, so need to know how to submit that form data without the form needing to be submitted again. Below is the new code: function submitData() { $("#submitProvData").submit(function(event) { event.preventDefault(); var gTotal, sTotal, dfd; var dfd = new $.Deferred(); $('html,body').animate({ scrollTop: 0 }, 'fast'); $("#submitProvData input").css("border", "1px solid #aaaaaa"); $("#submitProvData input[readonly='readonly']").css("border", "none"); sTotal = $('#summaryTotal').val(); gTotal = $('#gptotal').val(); if(gTotal !== 'sTotal'){ $("#newsupinvbox").append('<div id="newsupinvdiagbox" title="Warning - Totals do not match" class="hidden"><p>Press "Continue", to submit the invoice flagged for attention.</p> <br /><p class="italic">or</p><br /> <p>Press "Correct" to correct the discrepancy.</p></div>') //CREATE DIV //SET $("#newsupinvdiagbox").dialog({ resizable: false, autoOpen:false, modal: true, draggable: false, width:380, height:240, closeOnEscape: false, position: ['center',20], buttons: { 'Continue': function() { $(this).dialog('close'); reData(); }, // end continue button 'Correct': function() { $(this).dialog('close'); return false; } //end cancel button }//end buttons });//end dialog $('#newsupinvdiagbox').dialog('open'); } return false; }); } function reData() { console.log('submitted'); $("#submitProvData").submit(function(resubmit){ console.log('form submit'); var formData; formData = new FormData($(this)[0]); $.ajax({ type: "POST", url: "functions/invoicing_upload_provider.php", data: formData, async: false, success: function(result) { $.each($.parseJSON(result), function(item, value){ if(item == 'Success'){ $('#newsupinv_window_message_success_mes').html('The provider invoice was uploaded successfully.'); $('#newsupinv_window_message_success').fadeIn(300, function (){ reset(); }).delay(2500).fadeOut(700); } else if(item == 'Error'){ $('#newsupinv_window_message_error_mes').html(value); $('#newsupinv_window_message_error').fadeIn(300).delay(3000).fadeOut(700); } else if(item == 'Warning'){ $('#newsupinv_window_message_warning_mes').html(value); $('#newsupinv_window_message_warning').fadeIn(300, function (){ reset(); }).delay(2500).fadeOut(700); } }); }, error: function() { $('#newsupinv_window_message_error_mes').html("An error occured, the form was not submitted"); $('#newsupinv_window_message_error').fadeIn(300); $('#newsupinv_window_message_error').delay(3000).fadeOut(700); }, cache: false, contentType: false, processData: false }); }); }

  • BB Code Parser (in formatting phase) with jQuery jammed due to messed up loops most likely

    - by Oskar
    Greetings everyone, I'm making a BB Code Parser but I'm stuck on the JavaScript front. I'm using jQuery and the caret library for noting selections in a text field. When someone selects a piece of text a div with formatting options will appear. I have two issues. Issue 1. How can I make this work for multiple textfields? I'm drawing a blank as it currently will detect the textfield correctly until it enters the $("#BBtoolBox a").mousedown(function() { } loop. After entering it will start listing one field after another in a random pattern in my eyes. !!! MAIN Issue 2. I'm guessing this is the main reason for issue 1 as well. When I press a formatting option it will work on the first action but not the ones afterwards. It keeps duplicating the variable parsed. (if I only keep to one field it will never print in the second) Issue 3 If you find anything especially ugly in the code, please tell me how to improve myself. I appriciate all help I can get. Thanks in advance $(document).ready(function() { BBCP(); }); function BBCP(el) { if(!el) { el = "textarea"; } // Stores the cursor position of selection start $(el).mousedown(function(e) { coordX = e.pageX; coordY = e.pageY; // Event of selection finish by using keyboard }).keyup(function() { BBtoolBox(this, coordX, coordY); // Event of selection finish by using mouse }).mouseup(function() { BBtoolBox(this, coordX, coordY); // Event of field unfocus }).blur(function() { $("#BBtoolBox").hide(); }); } function BBtoolBox(el, coordX, coordY) { // Variable containing the selected text by Caret selection = $(el).caret().text; // Ignore the request if no text is selected if(selection.length == 0) { $("#BBtoolBox").hide(); return; } // Print the toolbox if(!document.getElementById("BBtoolBox")) { $(el).before("<div id=\"BBtoolBox\" style=\"left: "+ ( coordX + 5 ) +"px; top: "+ ( coordY - 30 ) +"px;\"></div>"); // List of actions $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_bold.png\" alt=\"B\" title=\"Bold\" /></a>"); $("#BBtoolBox").append("<a href=\"#\" onclick=\"return false\"><img src=\"./icons/text_italic.png\" alt=\"I\" title=\"Italic\" /></a>"); } else { $("#BBtoolBox").css({'left': (coordX + 3) +'px', 'top': (coordY - 30) +'px'}).show(); } // Parse the text according to the action requsted $("#BBtoolBox a").mousedown(function() { switch($(this).children(":first").attr("alt")) { case "B": // bold parsed = "[b]"+ selection +"[/b]"; break; case "I": // italic parsed = "[i]"+ selection +"[/i]"; break; } // Changes the field value by replacing the selection with the variable parsed $(el).val($(el).caret().replace(parsed)); $("#BBtoolBox").hide(); return false; }); }

  • Can't display Tool Tips in VC++6.0

    - by Paul
    I'm missing something fundamental, and probably both simple and obvious. My issue: I have a view (CPlaybackView, derived from CView). The view displays a bunch of objects derived from CRectTracker (CMpRectTracker). These objects each contain a floating point member. I want to display that floating point member when the mouse hovers over the CMpRectTracker. The handler method is never executed, although I can trace through OnIntitialUpdate, PreTranslateMessage, and OnMouseMove. This is in Visual C++ v. 6.0. Here's what I've done to try to accomplish this: 1. In the view's header file: public: BOOL OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult); private: CToolTipCtrl m_ToolTip; CMpRectTracker *m_pCurrentRectTracker;//Derived from CRectTracker 2. In the view's implementation file: a. In Message Map: ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNeedText) b. In CPlaybackView::OnInitialUpdate: if (m_ToolTip.Create(this, TTS_ALWAYSTIP) && m_ToolTip.AddTool(this)) { m_ToolTip.SendMessage(TTM_SETMAXTIPWIDTH, 0, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_AUTOPOP, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_INITIAL, 200); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_RESHOW, 200); } else { TRACE("Error in creating ToolTip"); } this->EnableToolTips(); c. In CPlaybackView::OnMouseMove: if (::IsWindow(m_ToolTip.m_hWnd)) { m_pCurrentRectTracker = NULL; m_ToolTip.Activate(FALSE); if(m_rtMilepostRect.HitTest(point) >= 0) { POSITION pos = pDoc->m_rtMilepostList.GetHeadPosition(); while(pos) { CMpRectTracker tracker = pDoc->m_rtMilepostList.GetNext(pos); if(tracker.HitTest(point) >= 0) { m_pCurrentRectTracker = &tracker; m_ToolTip.Activate(TRUE); break; } } } } d. In CPlaybackView::PreTranslateMessage: if (::IsWindow(m_ToolTip.m_hWnd) && pMsg->hwnd == m_hWnd) { switch(pMsg->message) { case WM_LBUTTONDOWN: case WM_MOUSEMOVE: case WM_LBUTTONUP: case WM_RBUTTONDOWN: case WM_MBUTTONDOWN: case WM_RBUTTONUP: case WM_MBUTTONUP: m_ToolTip.RelayEvent(pMsg); break; } } e. Finally, the handler method: BOOL CPlaybackView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult) { BOOL bHandledNotify = FALSE; CPoint CursorPos; VERIFY(::GetCursorPos(&CursorPos)); ScreenToClient(&CursorPos); CRect ClientRect; GetClientRect(ClientRect); // Make certain that the cursor is in the client rect, because the // mainframe also wants these messages to provide tooltips for the // toolbar. if (ClientRect.PtInRect(CursorPos)) { TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR; CString str; str.Format("%f", m_pCurrentRectTracker->GetMilepost()); ASSERT(str.GetLength() < sizeof(pTTT->szText)); ::strcpy(pTTT->szText, str); bHandledNotify = TRUE; } return bHandledNotify; }

  • Lockless queue implementation ends up having a loop under stress

    - by Fozi
    I have lockless queues written in C in form of a linked list that contains requests from several threads posted to and handled in a single thread. After a few hours of stress I end up having the last request's next pointer pointing to itself, which creates an endless loop and locks up the handling thread. The application runs (and fails) on both Linux and Windows. I'm debugging on Windows, where my COMPARE_EXCHANGE_PTR maps to InterlockedCompareExchangePointer. This is the code that pushes a request to the head of the list, and is called from several threads: void push_request(struct request * volatile * root, struct request * request) { assert(request); do { request->next = *root; } while(COMPARE_EXCHANGE_PTR(root, request, request->next) != request->next); } This is the code that gets a request from the end of the list, and is only called by a single thread that is handling them: struct request * pop_request(struct request * volatile * root) { struct request * volatile * p; struct request * request; do { p = root; while(*p && (*p)->next) p = &(*p)->next; // <- loops here request = *p; } while(COMPARE_EXCHANGE_PTR(p, NULL, request) != request); assert(request->next == NULL); return request; } Note that I'm not using a tail pointer because I wanted to avoid the complication of having to deal with the tail pointer in push_request. However I suspect that the problem might be in the way I find the end of the list. There are several places that push a request into the queue, but they all look generaly like this: // device->requests is defined as struct request * volatile requests; struct request * request = malloc(sizeof(struct request)); if(request) { // fill out request fields push_request(&device->requests, request); sem_post(device->request_sem); } The code that handles the request is doing more than that, but in essence does this in a loop: if(sem_wait_timeout(device->request_sem, timeout) == sem_success) { struct request * request = pop_request(&device->requests); // handle request free(request); } I also just added a function that is checking the list for duplicates before and after each operation, but I'm afraid that this check will change the timing so that I will never encounter the point where it fails. (I'm waiting for it to break as I'm writing this.) When I break the hanging program the handler thread loops in pop_request at the marked position. I have a valid list of one or more requests and the last one's next pointer points to itself. The request queues are usually short, I've never seen more then 10, and only 1 and 3 the two times I could take a look at this failure in the debugger. I thought this through as much as I could and I came to the conclusion that I should never be able to end up with a loop in my list unless I push the same request twice. I'm quite sure that this never happens. I'm also fairly sure (although not completely) that it's not the ABA problem. I know that I might pop more than one request at the same time, but I believe this is irrelevant here, and I've never seen it happening. (I'll fix this as well) I thought long and hard about how I can break my function, but I don't see a way to end up with a loop. So the question is: Can someone see a way how this can break? Can someone prove that this can not? Eventually I will solve this (maybe by using a tail pointer or some other solution - locking would be a problem because the threads that post should not be locked, I do have a RW lock at hand though) but I would like to make sure that changing the list actually solves my problem (as opposed to makes it just less likely because of different timing).

  • Removing google mail markers with jquery after getting them from xml

    - by sebastian
    Hi there, I'm trying to create a page that contains a google map. The map is filled with markers from an xml file. I just can't figure out how to remove "old" markers, that don't match the latest user input. At the moment my js stops after the very first xml item. The clearList.push(marker); is supposed to put the generated marker away for later usage. When the user hits the search button I want all markers to be gone and use clearMarkers();. Maybe someone here can help Sebastian Here is my JavaScript: $(document).ready(function() { $("#map").css({height: 650}); var clearList = []; var myLatLng = new google.maps.LatLng(52.518143, 13.372879); MYMAP.init('#map', myLatLng, 11); $("#showmarkers").click(function(e){ clearMarkers(); MYMAP.placeMarkers('markers.xml'); }); }); function clearMarkers() { $(clearList).each(function () { this.setmap(null); }); clearList = []; } var MYMAP = { map: null, bounds: null } MYMAP.init = function(selector, latLng, zoom) { var myOptions = { zoom:zoom, center: latLng, mapTypeId: google.maps.MapTypeId.HYBRID } this.map = new google.maps.Map($(selector)[0], myOptions); this.bounds = new google.maps.LatLngBounds(); } MYMAP.placeMarkers = function(filename) { $.get(filename, function(xml){ $(xml).find("marker").each(function(){ // read values from xml for searching var platzart = $(this).find('platzart').text(); var ort = $(this).find('ort').text(); var open = $(this).find('open').text(); if (platzart =="Kunstrasen" && $('#kunstrasen').attr('checked') || platzart =="Rasen" && $('#rasen').attr('checked') || platzart =="Tartan" && $('#tartan').attr('checked') || platzart =="Boltzplatz" && $('#boltzplatz').attr('checked') ){ // read values from xml for additional info var name = $(this).find('name').text(); var plz = $(this).find('plz').text(); var note = $(this).find('note').text(); var adress = $(this).find('adress').text(); // create a new LatLng point for the marker var lat = $(this).find('lat').text(); var lng = $(this).find('lng').text(); var point = new google.maps.LatLng(parseFloat(lat),parseFloat(lng)); // extend the bounds to include the new point MYMAP.bounds.extend(point); // create new marker var marker = new google.maps.Marker({ position: point, map: MYMAP.map }); clearList.push(marker); // add onclick overlay var infoWindow = new google.maps.InfoWindow(); var html='<strong>'+name+'</strong.><br />'+platzart; google.maps.event.addListener(marker, 'click', function() { infoWindow.setContent(html); infoWindow.open(MYMAP.map, marker); }); } MYMAP.map.fitBounds(MYMAP.bounds); }); }); } Thanks in advance

  • Nested loops break out unexpectedly

    - by Metju
    Hi guys, I'm trying to create a sudoku game, for those that do not know what it is. You have a 9x9 box that needs to be filled with numbers from 1-9, every number must be unique in its row and column, and also in the 3x3 box it is found. I ended up doing loads of looping within a 2 dimensional array. But at some point it just stops, with no exceptions whatsoever, just breaks out and nothing happens, and it's not always at the same position, but always goes past half way. I was expecting a stack overflow exception at least. Here's my code: public class Engine { public int[,] Create() { int[,] outer = new int[9, 9]; for (int i = 0; i < 9; i++) { for (int j = 0; j < 9; j++) { outer[i, j] = GetRandom(GetUsed(outer, i, j)); } } return outer; } List<int> GetUsed(int[,] arr, int x, int y) { List<int> usedNums = new List<int>(); for (int i = 0; i < 9; i++) { if (arr[x, i] != 0 && i != y) { if(!usedNums.Contains(arr[x, i])) usedNums.Add(arr[x, i]); } } for (int i = 0; i < 9; i++) { if (arr[i, y] != 0 && i != x) { if (!usedNums.Contains(arr[i, y])) usedNums.Add(arr[i, y]); } } int x2 = 9 - (x + 1); int y2 = 9 - (y + 1); if (x2 <= 3) x2 = 2; else if (x2 > 3 && x2 <= 6) x2 = 5; else x2 = 8; if (y2 <= 3) y2 = 2; else if (y2 > 3 && y2 <= 6) y2 = 5; else y2 = 8; for (int i = x2 - 2; i < x2; i++) { for (int j = y2 - 2; j < y2; j++) { if (arr[i, j] != 0 && i != x && j != y) { if (!usedNums.Contains(arr[i, j])) usedNums.Add(arr[i, j]); } } } return usedNums; } int GetRandom(List<int> numbers) { Random r; int newNum; do { r = new Random(); newNum = r.Next(1, 10); } while (numbers.Contains(newNum)); return newNum; } }

  • multple inner joins 3 or more crashes mysql server 5.1.30 opensolaris

    - by user331849
    when doing simple query on 4 inner joined tables, the server crashes with the output below appearing in the the mysql .err file. eg. select * from table1 inner join table2 on table1.a = table2.a and table1.b = table2.b inner join table3 on table2.a = table3.a and table2.c = table3.c inner join table4 on table3.a = table4.a and table3.d = table4.d If i remove one of the tables it executes fine.

  • C++ std::vector insert segfault

  • Does anyone know how to layout a JToolBar that does't move or re-size any components placed in it?

    - by S1.Mac
    Can anyone help with this problem i'm trying to create a JToolBar and I want all its components to be fixed in size and position. I'v tried a few different layout managers but they all center and/or re-size the components when the frame its in is re-sized. here is an example using GridbagLayout, I have also used the default layout manager using the toolbar.add( component ) method but the result is the same : ' import java.awt.BorderLayout; import java.awt.Component; import java.awt.Dimension; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.*; public class ToolBarTest extends JFrame { private JToolBar toolbar; private JPanel mainPanel; private JPanel toolBarPanel; private JButton aButton; private JCheckBox aCheckBox; private JList aList; private Box toolbarBox; private GridBagConstraints toolbarConstraints; private GridBagLayout toolbarLayout; private JLabel shapeLabel; private JComboBox<ImageIcon> shapeChooser; private JLabel colorLabel; private JComboBox colorChooser; private String colorNames[] = { "Black" , "Blue", "Cyan", "Dark Gray", "Gray", "Green", "Light Gray", "Magenta", "Orange", "Pink", "Red", "White", "Yellow", "Custom" }; private String shapeNames[] = { "Line", "Oval", "Rectangle", "3D Rectangle","Paint Brush", "Rounded Rectangle" }; public ToolBarTest() { setLayout( new BorderLayout() ); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); setSize( 500, 500 ); add( createToolBar(), BorderLayout.PAGE_START ); setVisible( true ); } public void addToToolbar( Component component, int row, int column ) { toolbarConstraints.gridx = column; toolbarConstraints.gridy = row; toolbarConstraints.anchor = GridBagConstraints.WEST; toolbarConstraints.fill = GridBagConstraints.NONE; toolbarConstraints.weightx = 0; toolbarConstraints.weighty = 0; toolbarConstraints.gridwidth = 1; toolbarConstraints.gridheight = 1; toolbarLayout.setConstraints( component, toolbarConstraints ); toolbar.add( component ); }// end addToToolbar public final JToolBar createToolBar() { toolbarLayout = new GridBagLayout(); toolbarConstraints = new GridBagConstraints(); // create the tool bar which holds the items to draw toolbar = new JToolBar(); toolbar.setBorderPainted(true); toolbar.setLayout( toolbarLayout ); toolbar.setFloatable( true ); shapeLabel = new JLabel( "Shapes: " ); addToToolbar( shapeLabel, 0, 1 ); String iconNames[] = { "PaintImages/Line.jpg", "PaintImages/Oval.jpg", "PaintImages/Rect.jpg", "PaintImages/3DRect.jpg","PaintImages/PaintBrush.jpg", "PaintImages/RoundRect.jpg"}; ImageIcon shapeIcons[] = new ImageIcon[ shapeNames.length ]; // create image icons for( int shapeButton = 0; shapeButton < shapeNames.length; shapeButton++ ) { shapeIcons[ shapeButton ] = new ImageIcon( iconNames[ shapeButton ] ); }// end for shapeChooser = new JComboBox< ImageIcon >( shapeIcons ); shapeChooser.setSize( new Dimension( 50, 20 )); shapeChooser.setPrototypeDisplayValue( shapeIcons[ 0 ] ); shapeChooser.setSelectedIndex( 0 ); addToToolbar( shapeChooser, 0, 2 ); colorLabel = new JLabel( "Colors: " ); addToToolbar( colorLabel, 0, 3 ); colorChooser = new JComboBox( colorNames ); addToToolbar( colorChooser, 0, 4 ); return toolbar; }// end createToolBar public static void main( String args[] ) { new ToolBarTest(); }// end main }// end class ToolBarTest'
