• Reference WiX define made in included file.

  - by leiflundgren

  I have a defines.wxi-file which contains some good definitions used in all my wxs-files. When I attempt to reference the defined value I get Undefined preprocessor variable '$(var.MAGE_FOLDER)' back in my face. I guess there is something trivial I am missing here... Any ideas? defines.wxi <Include> <?define IMAGE_FOLDER="Images" ?> </Include> Product.wxs <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> <?Include defines.wxi ?> <Product ... > <Component Id='c.Images' Directory='$(var.IMAGE_FOLDER)' />

• Loading external pngs into an AS2 swf that is loaded into an AS3 swf wrapper

  - by James Fassett

  I have a Wrapper SWF that loads a series of AS2 movies. Each AS2 movie loads a series of .png files. AS3_wrapper.swf |-> AS2_1.swf |-> image_1.png |-> image_2.png |-> AS2_2.swf |-> image_1.png |-> image_2.png Inside of the AS2 I listen for the load of the pngs using onLoadInit and update my UI. This works fine for the first AS2 swf. But when I load the second AS2 swf the onLoadInit isn't triggered for the pngs. My guess is that the images are in a cache or something like that. I put a random string on the end of the request to try and avoid the cache but that doesn't seem to work. The code in the as2 looks roughly like this: var flagLoader:MovieClipLoader = new MovieClipLoader(); var listener:Object = new Object(); listener.onLoadInit = Delegate.create(this, handleImageLoad); flagLoader.addListener(listener); var row:MovieClip = frame1["row" + (numLoaded + 1)]; flagLoader.loadClip(predictionData[numLoaded].flag + "?r="+Math.random(), row.flag); I'm making sure to load only one image at a time (I've read anecdotal evidence loading more than one thing at a time can confuse the MovieClipLoader). For the first as2 file everything works great. When I load the second as2 file the handleImageLoad never gets called. Update: Even more perplexing is if I reload the first AS2 movie (after the second AS2 movie fails to load the images) the first AS2 movie loads the images again fine. Update 2: After trying to change from using a MovieClipLoader to polling (as was helpfully suggested) I have found some more evidence that is relevant. When I load the first AS2 files and trace from the top level clip it prints out _root. The second AS2 file when loaded traces the same _root. This lead me to check if they were clashing on names and they are. Both have a child called frame. The first one, when I trace it comes out as _root.frame as expected. The second AS2 file traces _level0.instance3.instance118.instance111.frame. I'm guessing this is related to the problem. Flash is keeping the _root of the two files the same but it is changing the locations of their children (for subsequently loaded files that have children with the same names). So either the onLoad is going to the wrong clip or the events about it loading are.

• Joomla 1.5 Media Manager sets incorrect file permissions when uploading

  - by Scott Mayfield

  Howdy all, I have a Joomla 1.5 installation running on Windows Server 2008, installed via the Web Platform Installer. When uploading images with the media manager (native uploader, not the flash bulk uploader), the files arrive on the server correctly, but are given incorrect permissions. Specifically, the IIS_IUSRS group is not given access to the file. I might be incorrect about what group/user is SUPPOSED to get access to the files, but so far, I've found that unless I give IIS_IUSRS access to the uploaded files, they won't appear on the site or in the media manager (appear as broken images). Once I give IIS_IUSRS permission to the files, they work fine. So far, all the research I've done has led me to linux specific fixes that involve either changing the umask on the server, or directly modifying the Joomla codebase to add an appropriate chmod command to the upload process, but I really don't want to modify Joomla directly. I have to believe there's a setting here somewhere that will do the job, either on the Joomla or Windows side of the equation. Any thoughts? Scott

• imagejpeg memory exhaustion

  - by 0plus1

  I'm creating thumbnails cycling through a lot of images, when I find a large image I get: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 13056 bytes) Now I already know how to circumvent this with: ini_set('memory_limit', '-1'); What I want to know is why it exhaust the memory! Is there some debug tools that will show me exactly when memory is exhausting? And specifically that will show me if there are variables/arrays that are killing my memory? OR, are there better way to resize images other then: $thumb=imagecreatetruecolor($newwidth,$newheight); $source=imagecreatefromjpeg($imgfile); imagecopyresampled($thumb,$source,0,0,0,0,$newwidth,$newheight,$width,$height); imagejpeg($thumb,$destinationfile,85); ? Thank you very much!

• Is there any project estimation tool to give estimate for web design/ development work?

  - by jitendra

  Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

• Best Design pattern for social media file transfer

  - by Onema

  Our system would like our clients to link their accounts with different social media sites like youtube, vimeo, facebook, myspace and so on. One of the benefits we would like to give to the user is to transfer, update and delete files they have uploaded to our sites and transfer them to the social media sites mentioned above. this files could be videos, images or audio. We started thinking about using a strategy pattern, as all of these sites share a common process ( authentication, connection, use the API to transfer/edit/delete the file ), but we soon realized that it may not work as me may want to use some of the extended functionality that is specific to each service (eg: associate a youtube video with a channel, or upload images to a specific album on facebook, and much, much more...) My question is, what would be the best Structural Design Patter to use for this scenario?

• Python: Retrieve Image from MSSQL

  - by KoRkOnY

  Dear All, I'm working on a Python project that retrieves an image from MSSQL. My code is able to retrieve the images successfully but with a fixed size of 63KB. if the image is greater than that size, it just brings the first 63KB from the image! The following is my code: #!/usr/bin/python import _mssql mssql=_mssql.connect('<ServerIP>','<UserID>','<Password>') mssql.select_db('<Database>') x=1 while x==1: query="select TOP 1 * from table;" if mssql.query(query): rows=mssql.fetch_array() rowNumbers = rows[0][1] #print "Number of rows fetched: " + str(rowNumbers) for row in rows: for i in range(rowNumbers): FILE=open('/home/images/' + str(row[2][i][1]) + '-' + str(row[2][i][2]).strip() + ' (' + str(row[2][i][0]) + ').jpg','wb') FILE.write(row[2][i][4]) FILE.close() print 'Successfully downloaded image: ' + str(row[2][i][0]) + '\t' + str(row[2][i][2]).strip() + '\t' + str(row[2][i][1]) else: print mssql.errmsg() print mssql.stdmsg() mssql.close()

• HTML Upload Form will only upload files found in the directory of the PHP file.

  - by vette982

  I have an image uploader that uses the imgur.com API and jQuery's .ajax() function to upload images to their servers. However, if I browse for an image using the <input type="file"/> element of the form, it will only be successful in uploading an image if the image file is found in the same directory as the page.php file that the form is found in (shown below). How can I allow the form to upload images from any directory on my computer? page.php: <form action="page.php" method="post"> <input type="file" name="doc" id="doc" /><br/> <input type="image" src="go.gif" name="submit" id="submit" /> </form>

• Detecting a image 404 in javascript.

  - by xal

  After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3. I'm looking for a way to detect that a certain image failed to load correctly (404) in a cross browser way. If that happens, we want to use JS to show a spinner in it's place and reload the image every few seconds until it can be successfully loaded from s3.

• ImageMagick: convert png fail via PHP and works via bash shell

  - by wedix

  I've got a very weird bug which I've yet to find a solution. UPDATE see solution below What I am trying to do is convert a full size picture into a 160x120 thumbnail. It works great with jpg and jpeg files of any size, but not with png. ImageMagick command: /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' PHP function (shortened) ... $cmd = "/opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png'"; exec($cmd, $output, $retval); $errors += $retval; if ($errors > 0) { die(print_r($output)); } When this function runs $retval equal 1 which means the convert command failed (thumbnail isn't created). This is where it gets interesting, if I run the exact same command in my shell, it works. wedbook:~ wedix$ /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' wedbook:~ wedix$ I've tried using different PHP function such as system, passthru but it didn't work. I thought maybe someone here knew the solution. I'm using MAMP 1.7.2 Apache/2.0.59 PHP/5.2.6 Thanks! UPDATE I updated the following dependencies libpng from 1.2.35 to 1.2.37 libiconv from 1.12_2 to 1.13_0 ImageMagick 6.5.2-4_1 to 6.5.2-9_0 However, it did not fix my problem. 2nd UPDATE I finally found something that might help, when the function runs this is what gets printed in the Apache logs: dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/bin/convert Reason: Incompatible library version: convert requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 3rd UPDATE libiconv.2.dylib is version 8.0.0... bash-3.2$ otool -L /opt/local/lib/libiconv.2.dylib /opt/local/lib/libiconv.2.dylib: /opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4) 4th UPDATE Problem was related to MAMP, see solution below

• How do I use IImgCtx to get load an image with an alpha channel?

  - by fret

  I have some working code that uses IImgCtx to load images, but I can't work out how to get at the alpha channel. For images like .gif's and .png's there are transparent pixels, but using anything other than a 24-bit bitmap as a drawing surface doesn't work. For reference on the interface: http://www.codeproject.com/KB/graphics/JianImgCtxDecoder.aspx My code looks like this: IImgCtx *Ctx = 0; HRESULT hr = CoCreateInstance(CLSID_IImgCtx, NULL, CLSCTX_INPROC_SERVER, IID_IImgCtx, (LPVOID*)&Ctx); if (SUCCEEDED(hr)) { GVariant Fn = Name; hr = Ctx->Load(Fn.WStr(), 0); if (SUCCEEDED(hr)) { SIZE Size = { -1, -1 }; ULONG State = 0; while (true) { hr = Ctx->GetStateInfo(&State, &Size, false); if (SUCCEEDED(hr)) { if ((State & IMGLOAD_COMPLETE) || (State & IMGLOAD_STOPPED) || (State & IMGLOAD_ERROR)) { break; } else { LgiSleep(1); } } else break; } if (Size.cx > 0 && Size.cy > 0 && pDC.Reset(new GMemDC)) { if (pDC->Create(Size.cx, Size.cy, 32)) { HDC hDC = pDC->StartDC(); if (hDC) { RECT rc = { 0, 0, pDC->X(), pDC->Y() }; Ctx->Draw(hDC, &rc); pDC->EndDC(); } } else pDC.Reset(); } } Ctx->Release(); Where "StartDC" basically wraps CreateCompatibleDC(NULL) and "EndDC" wraps DeleteDC, with appropriate SelectObjects for the HBITMAPS etc. And pDC-Create(x, y, bit_depth) calls CreateDIBSection(...DIB_RGB_COLORS...). So it works if I create a 24 bits/pixel bitmap but has no alpha to speak of, and it leaves the 32 bits/pixel bitmap blank. Now this interface apparently is used by Internet Explorer to load images, and obviously THAT supports transparency, so I believe that it's possible to get some level of alpha out of the interface. The question is how? (I also have fall back code that will call libpng/libjpeg/my .gif loader etc)

• OnPage Load display one sentence - hide others

  - by Paul

  Hi I have created http://techavid.com/design/test3.html and when you load the page you see there are 3 images. The sun image is focused(in color), while the others are greyed out until clicked. That is how it should be for the images. Under each image you see a sentence 1st: Sun, 2nd: Airplane & 3rd: Nano, but when page loads you see all three sentences. How to make it so when page loads the first sentence underneath the active image (sun) shows only and the others do not show, they only show when clicked (though that works just need to figure out onpage load only show "1st: Sun")? thanks :) paul J.

• PNGs alpha transparancy in AS3 - Unknown file-type

  - by WiseDonkey

  Hello there! After whittling down of the options we've encountered a problem with PNG's and ActionScript 3 (AS3). When loading a PNG 8 or PNG 32 with alpha transparancy we're getting the following error reported in Flash:- "Error #2124: Loaded file is an unknown type" Now, we're dealing with some legacy images, and it appears as though this problem isn't universal - some images believed to be 32bit alpha PNG are loading. BUT, some conclusions:- converting one image that was 32 bit alpha (NOT WORKING IN AS3) to PNG 8 index transparency DID work. And converting that same image to PNG 8 alpha DID NOT work. These all worked in AS2 There is no difference between the headers Headers of a Failing Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:17:28 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Tue, 06 Apr 2010 13:44:05 GMT [4] => ETag: "3700054-11d6-a3983340" [5] => Accept-Ranges: bytes [6] => Content-Length: 4566 [7] => Connection: close [8] => Content-Type: image/png Headers of a Working Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:19:02 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Fri, 30 Oct 2009 18:38:08 GMT [4] => ETag: "ba8057-65f2-5445c400" [5] => Accept-Ranges: bytes [6] => Content-Length: 26098 [7] => Connection: close [8] => Content-Type: image/png Any thoughts of a direction of further investigation or thoughts on a bewildering problem with little to no documentation; very warmly welcomed. EDIT Now it would appear as though something in the PHP conversion of the images is shafting; I use the following PHP to add alpha layers:- imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT);

• JPanel Layout Image Cutoff

  - by Trizicus

  I am adding images to a JPanel but the images are getting cut off. I was originally trying BorderLayout but that only worked for one image and adding others added image cut-off. So I switched to other layouts and the best and closest I could get was BoxLayout however that adds a very large cut-off which is not acceptable either. So basically; How can I add images (from a custom JComponent) to a custom JPanel without bad effects such as the one present in the code. Custom JPanel: import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.BoxLayout; import javax.swing.JPanel; import javax.swing.Timer; public class GraphicsPanel extends JPanel implements MouseListener { private Entity test; private Timer timer; private long startTime = 0; private int numFrames = 0; private float fps = 0.0f; GraphicsPanel() { test = new Entity("test.png"); Thread t1 = new Thread(test); t1.start(); Entity ent2 = new Entity("images.jpg"); ent2.setX(150); ent2.setY(150); Thread t2 = new Thread(ent2); t2.start(); Entity ent3 = new Entity("test.png"); ent3.setX(0); ent3.setY(150); Thread t3 = new Thread(ent3); t3.start(); //ESSENTIAL setLayout(new BoxLayout(this, BoxLayout.X_AXIS)); add(test); add(ent2); add(ent3); //GAMELOOP timer = new Timer(30, new Gameloop(this)); timer.start(); addMouseListener(this); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2 = (Graphics2D) g.create(); g2.setClip(0, 0, getWidth(), getHeight()); g2.setColor(Color.BLACK); g2.drawString("FPS: " + fps, 1, 15); } public void getFPS() { ++numFrames; if (startTime == 0) { startTime = System.currentTimeMillis(); } else { long currentTime = System.currentTimeMillis(); long delta = (currentTime - startTime); if (delta > 1000) { fps = (numFrames * 1000) / delta; numFrames = 0; startTime = currentTime; } } } public void mouseClicked(MouseEvent e) {} public void mousePressed(MouseEvent e) {} public void mouseReleased(MouseEvent e) {} public void mouseEntered(MouseEvent e) { } public void mouseExited(MouseEvent e) { } class Gameloop implements ActionListener { private GraphicsPanel gp; Gameloop(GraphicsPanel gp) { this.gp = gp; } public void actionPerformed(ActionEvent e) { try { gp.getFPS(); gp.repaint(); } catch (Exception ez) { } } } } Main class: import java.awt.EventQueue; import javax.swing.JFrame; public class MainWindow { public static void main(String[] args) { new MainWindow(); } private JFrame frame; private GraphicsPanel gp = new GraphicsPanel(); MainWindow() { EventQueue.invokeLater(new Runnable() { public void run() { frame = new JFrame("Graphics Practice"); frame.setSize(680, 420); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(gp); } }); } } Custom JComponent import java.awt.Color; import java.awt.Dimension; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.image.BufferedImage; import javax.imageio.ImageIO; import javax.swing.JComponent; public class Entity extends JComponent implements Runnable { private BufferedImage bImg; private int x = 0; private int y = 0; private int entityWidth, entityHeight; private String filename; Entity(String filename) { this.filename = filename; } public void run() { bImg = loadBImage(filename); entityWidth = bImg.getWidth(); entityHeight = bImg.getHeight(); setPreferredSize(new Dimension(entityWidth, entityHeight)); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g.create(); g2d.drawImage(bImg, x, y, null); g2d.dispose(); } public BufferedImage loadBImage(String filename) { try { bImg = ImageIO.read(getClass().getResource(filename)); } catch (Exception e) { } return bImg; } public int getEntityWidth() { return entityWidth; } public int getEntityHeight() { return entityHeight; } public int getX() { return x; } public int getY() { return y; } public void setX(int x) { this.x = x; } public void setY(int y) { this.y = y; } }

• Adding a generic image field onto a ModelForm in django

  - by Prairiedogg

  I have two models, Room and Image. Image is a generic model that can tack onto any other model. I want to give users a form to upload an image when they post information about a room. I've written code that works, but I'm afraid I've done it the hard way, and specifically in a way that violates DRY. Was hoping someone who's a little more familiar with django forms could point out where I've gone wrong. Update: I've tried to clarify why I chose this design in comments to the current answers. To summarize: I didn't simply put an ImageField on the Room model because I wanted more than one image associated with the Room model. I chose a generic Image model because I wanted to add images to several different models. The alternatives I considered were were multiple foreign keys on a single Image class, which seemed messy, or multiple Image classes, which I thought would clutter my schema. I didn't make this clear in my first post, so sorry about that. Seeing as none of the answers so far has addressed how to make this a little more DRY I did come up with my own solution which was to add the upload path as a class attribute on the image model and reference that every time it's needed. # Models class Image(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') image = models.ImageField(_('Image'), height_field='', width_field='', upload_to='uploads/images', max_length=200) class Room(models.Model): name = models.CharField(max_length=50) image_set = generic.GenericRelation('Image') # The form class AddRoomForm(forms.ModelForm): image_1 = forms.ImageField() class Meta: model = Room # The view def handle_uploaded_file(f): # DRY violation, I've already specified the upload path in the image model upload_suffix = join('uploads/images', f.name) upload_path = join(settings.MEDIA_ROOT, upload_suffix) destination = open(upload_path, 'wb+') for chunk in f.chunks(): destination.write(chunk) destination.close() return upload_suffix def add_room(request, apartment_id, form_class=AddRoomForm, template='apartments/add_room.html'): apartment = Apartment.objects.get(id=apartment_id) if request.method == 'POST': form = form_class(request.POST, request.FILES) if form.is_valid(): room = form.save() image_1 = form.cleaned_data['image_1'] # Instead of writing a special function to handle the image, # shouldn't I just be able to pass it straight into Image.objects.create # ...but it doesn't seem to work for some reason, wrong syntax perhaps? upload_path = handle_uploaded_file(image_1) image = Image.objects.create(content_object=room, image=upload_path) return HttpResponseRedirect(room.get_absolute_url()) else: form = form_class() context = {'form': form, } return direct_to_template(request, template, extra_context=context)

• Finding distance travelled by robot using Optical Flow

  - by user280454

  Hi, I'm working on a project right now in which we are developing an autonomous robot. I have to basically find out the distance travelled by the robot between any 2 intervals. I'm using OpenCV, and using the Optical Flow functions of OpenCV, I'm able to find out the velocity/distance of each pixel in 2 different images. Using this information, I want to be able to find out the distance travelled by the robot in the interval between those 2 images. I thought of a way in which we could develop an input output mapping between the distance travelled by pixels and the distance travelled by the bot (using some tests). In this way, using neural networks, we would be able to find the relationship. However, the optical flow would depend on the distance of the camera from the pixel, which would cause problems. Is there any way to solve this problem?

• Prototype/Scriptaculous Cycle (Slideshow) Plugin

  - by Salman A

  I've got a bunch of websites that use a few Prototype/Scriptaculous plugins such as lightbox and modalbox, hence include references to these two libraries on various pages. I now need to implement a slideshow on every page, and to follow suit, I need a Prototype cycle or slideshow plugin. The requirements are fairly simple: images should fade-in/out every N seconds four controls: prev, pause, play, next i'd prefer to add images to the slideshow via JavaScript; not by adding too many tags Can any one suggest an existing plugin that can be customized easily and is not bloated like most of the other plugins. Here is a jQuery plugin which provides similar functionality: http://malsup.com/jquery/cycle/lite/

• How do I make a SignalR client something when it receives a message?

  - by Ben

  I want to do something when a client receives a message via a SignalR hub. I've put together a basic chat app, but want people to be able to "like" a chat comment. I'm thinking the way to do this is to find the chat message on the client's page and update it using javascript. In the meantime to "prove the concept" I just want to make an alert popup on the client machine to say another user likes the comment. Trouble is, I'm not sure where to put it. (Am struggling to find SignalR documentation to be honest.) can't get my head round what is calling what here. My ChatHub class is as follows: public class ChatHub : Hub { public void Send(string name, string message) { // Call the broadcastMessage method to update clients. Clients.All.broadcastMessage(name, message); } } And my JavaScript is: $(function () { // Declare a proxy to reference the hub. var chat = $.connection.chatHub; // Create a function that the hub can call to broadcast messages. chat.client.broadcastMessage = function (name, message) { // Html encode display name and message. var encodedName = $('<div />').text(name).html(); var encodedMsg = $('<div />').text(message).html(); // Add the message to the page. var divContent = $('#discussion').html(); $('#discussion').html('<div class="container">' + '<div class="content">' + '<p class="username">' + encodedName + '</p>' + '<p class="message">' + encodedMsg + '</p>' + '</div>' + '<div class="slideout">' + '<div class="clickme" onclick="slideMenu(this)"></div>' + '<div class="slidebutton"><img id="imgid" onclick="likeButtonClick(this)" src="Images/like.png" /></div>' + '<div class="slidebutton"><img onclick="commentButtonClick(this)" src="Images/comment.png" /></div>' + '<div class="slidebutton" style="margin-right:0px"><img onclick="redcardButtonClick(this)" src="Images/redcard.png" /></div>' + '</div>' + '</div>' + divContent); }; // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#lblUser').html(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); });
