  • WordPress 'comment is awaiting moderation.' message not appearing when a comment is submitted?

    - by cs
    Everything is pretty standard from WP samples, with minor modifications. But when a comment is submitted, it does not show the "your comment is awaiting moderation" message. The comments.php: <div id="comment-block"> <h4><?php comments_number('No Responses', 'One Response', '% Responses' );?> to &#8220;<?php the_title(); ?>&#8221;</h4> <ul id="commentlist"> <?php wp_list_comments('type=comment&callback=mytheme_comment'); ?> </ul> <?php // this is displayed if there are no comments so far ?> <?php if ('open' == $post->comment_status) : ?> <!-- If comments are open, but there are no comments. --> <?php else : // comments are closed ?> <!-- If comments are closed. --> <p class="nocomments">Comments are closed.</p> <?php endif; ?> <?php if ('open' == $post->comment_status) : ?> <h4>Leave a reply</h4> <div class="cancel-comment-reply"> <small><?php cancel_comment_reply_link(); ?></small> </div> <?php if ( get_option('comment_registration') && !$user_ID ) : ?> <p>You must be <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?redirect_to=<?php echo urlencode(get_permalink()); ?>">logged in</a> to post a comment.</p> <?php else : ?> <form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform"> <?php if ( $user_ID ) : ?> <p class="loggedIn">Logged in as <a href="<?php echo get_option('siteurl'); ?>/wp-admin/profile.php"><?php echo $user_identity; ?></a>. <a href="<?php echo wp_logout_url(get_permalink()); ?>" title="Log out of this account">Log out &raquo;</a></p> <?php else : ?> <table width="675" cellpadding="0" cellspacing="0" border="0"> <tr><td style="padding-right: 20px;"><label for="author">Name <?php if ($req) echo "(required)"; ?></label></td> <td style="padding-right: 20px;"><label for="email">Email <?php if ($req) echo "(required)"; ?></label> <small>(will not be published)</small></td> <td><label for="url">Website <?php if ($req) echo "(required)"; ?></label></td> </tr> <tr><td style="padding-right: 20px;"><input type="text" name="author" id="author" value="<?php echo $comment_author; ?>" class="text" tabindex="1" <?php if ($req) echo "aria-required='true'"; ?> /></td> <td style="padding-right: 20px;"><input type="text" name="email" id="email" value="<?php echo $comment_author_email; ?>" class="text" tabindex="2" <?php if ($req) echo "aria-required='true'"; ?> /></td> <td><input type="text" name="url" id="url" value="<?php echo $comment_author_url; ?>" class="text" tabindex="3" /></td> </tr> </table> <?php endif; ?> <label for="comment">Comment <?php if ($req) echo "(required)"; ?></label><br /> <textarea name="comment" id="comment" rows="10" tabindex="4" class="text"></textarea> <input name="submit" type="image" src="<?php bloginfo('template_directory'); ?>/images/submit_button.png" width="130" height="24" alt="Submit" id="submit" tabindex="5" /> <?php comment_id_fields(); ?> <?php do_action('comment_form', $post->ID); ?> </form> <div class="clear"></div> <?php endif; // If registration required and not logged in ?> </div> <?php endif; // if you delete this the sky will fall on your head ?> And the mytheme_comments function in functions.php function mytheme_comment($comment, $args, $depth) { $GLOBALS['comment'] = $comment; ?> <li <?php comment_class(); ?> id="li-comment-<?php comment_ID() ?>"> <div id="comment-<?php comment_ID(); ?>"> <span class="comment-author vcard"> <?php printf(__('<cite class="fn">%s</cite> <span class="says">says at</span>'), get_comment_author_link()) ?> </span> <?php if ($comment->comment_approved == '0') : ?> <em><?php _e('Your comment is awaiting moderation.') ?></em> <br /> <?php endif; ?> <span class="comment-meta commentmetadata"><a href="<?php echo htmlspecialchars( get_comment_link( $comment->comment_ID ) ) ?>"> <?php printf(__('%2$s, %1$s'), get_comment_date(), get_comment_time()) ?></a><?php edit_comment_link(__('(Edit)'),' ','') ?></span> <?php comment_text() ?> <div class="reply"> <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?> </div> </div> <?php } ?>

  • MVC 3 Client Validation works intermittently

    - by Gutek
    I have MVC 3 version, System.Web.Mvc product version is: 3.0.20105.0 modified on 5th of Jan 2011 - i think that's the latest. I’ve notice that client validation is not working as it suppose in the application that we are creating, so I’ve made a quick test. I’ve created basic MVC 3 Application using Internet Application template. I’ve added Test Controller: using System.Web.Mvc; using MvcApplication3.Models; namespace MvcApplication3.Controllers { public class TestController : Controller { public ActionResult Index() { return View(); } public ActionResult Create() { Sample model = new Sample(); return View(model); } [HttpPost] public ActionResult Create(Sample model) { if(!ModelState.IsValid) { return View(); } return RedirectToAction("Display"); } public ActionResult Display() { Sample model = new Sample(); model.Age = 10; model.CardNumber = "1324234"; model.Email = "[email protected]"; model.Title = "hahah"; return View(model); } } } Model: using System.ComponentModel.DataAnnotations; namespace MvcApplication3.Models { public class Sample { [Required] public string Title { get; set; } [Required] public string Email { get; set; } [Required] [Range(4, 120, ErrorMessage = "Oi! Common!")] public short Age { get; set; } [Required] public string CardNumber { get; set; } } } And 3 views: Create: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @*@{ Html.EnableClientValidation(); }*@ @using (Html.BeginForm()) { @Html.ValidationSummary(false) <fieldset> <legend>Sample</legend> <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Age) </div> <div class="editor-field"> @Html.EditorFor(model => model.Age) @Html.ValidationMessageFor(model => model.Age) </div> <div class="editor-label"> @Html.LabelFor(model => model.CardNumber) </div> <div class="editor-field"> @Html.EditorFor(model => model.CardNumber) @Html.ValidationMessageFor(model => model.CardNumber) </div> <p> <input type="submit" value="Create" /> </p> </fieldset> @*<fieldset> @Html.EditorForModel() <p> <input type="submit" value="Create" /> </p> </fieldset> *@ } <div> @Html.ActionLink("Back to List", "Index") </div> Display: @model MvcApplication3.Models.Sample @{ ViewBag.Title = "Display"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Display</h2> <fieldset> <legend>Sample</legend> <div class="display-label">Title</div> <div class="display-field">@Model.Title</div> <div class="display-label">Email</div> <div class="display-field">@Model.Email</div> <div class="display-label">Age</div> <div class="display-field">@Model.Age</div> <div class="display-label">CardNumber</div> <div class="display-field">@Model.CardNumber</div> </fieldset> <p> @Html.ActionLink("Back to List", "Index") </p> Index: @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <p> @Html.ActionLink("Create", "Create") </p> <p> @Html.ActionLink("Display", "Display") </p> Everything is default here – Create Controller, AddView from controller action with model specified with proper scaffold template and using provided layout in sample application. When I will go to /Test/Create client validation in most cases works only for Title and Age fields, after clicking Create it works for all fields (create does not goes to server). However in some cases (after a build) Title validation is not working and Email is, or CardNumber or Title and CardNumber but Email is not. But never all validation is working before clicking Create. I’ve tried creating form with Html.EditorForModel as well as enforce client validation just before BeginForm: @{ Html.EnableClientValidation(); } I’m providing a source code for this sample on dropbox – as maybe our dev env is broken :/ I’ve done tests on IE 8 and Chrome 10 beta. Just in case, in web config validation scripts are enabled: <appSettings> <add key="ClientValidationEnabled" value="true"/> <add key="UnobtrusiveJavaScriptEnabled" value="true"/> </appSettings> So my questions are Is there a way to ensure that Client validation will work as it supposed to work and not intermittently? Is this a desired behavior and I'm missing something in configuration/implementation?

  • asp.net mvc xval validation

    - by mctayl
    Hi there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully? My model goes like this using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace PitchPortal.Core { public class DocumentMetadata { //[Required] // public bool visibility { get; set; } [Required,StringLength(10, ErrorMessage = "title is too long")] public string title { get; set; } [Required, StringLength(10, ErrorMessage = "description is too long")] public string description { get; set; } [Required, StringLength(10, ErrorMessage = "summary is too long")] public string summary { get; set; } } } the html goes like this <div id="results" title="Upload results"/> <form id="myForm" action="<%=Url.Action("New") %>" method="post" enctype="multipart/form-data"> <% Html.EnableClientValidation(); %> <%= Html.ValidationSummary() %> <table> <tr> <td> <%=Html.Label("File")%></td> <td> <input type="file" id="file1" name="fileUpload" /> <br /> <%=Html.SubmitButton<DocumentController>(x => x.Upload(), "GetImage", "")%> </td> <td> <%=Html.ValidationMessage("file1")%> </td> </tr> <tr> <td> <%=Html.Label("Visible")%></td> <td> <%= Html.RadioButton( "visibility",true,true) %>true <%= Html.RadioButton("visibility", false)%>false </td> <td> <%= Html.ValidationMessage("visibility")%> </td> </tr> <tr> <td> <%=Html.Label("Title")%></td> <td> <%=Html.TextBox("doc.title")%></td> <td> <%= Html.ValidationMessage("doc.title")%></td> </tr> <tr> <td> <%=Html.Label("Description")%></td> <td><%= Html.TextArea("doc.description")%></td> <td><%= Html.ValidationMessage("doc.description")%></td> </tr> <tr> <td> <%=Html.Label("Summary")%></td> <td> <%= Html.TextArea("doc.summary")%></td> <td> <%= Html.ValidationMessage("doc.summary")%></td> </tr> <tr> <td> <%=Html.Label("Filetype")%></td> <td> <%= Html.DropDownList("Filetype_id", (IEnumerable<SelectListItem>)ViewData.Model.AllFiletypesList)%> </td> <td> <%= Html.ValidationMessage("doc.Filetype_id")%> </td> </tr> <tr> <td> <%=Html.Label("Category")%></td> <td><%= Html.DropDownList("cat.parent_id", (IEnumerable<SelectListItem>)ViewData.Model.AllCategoriesList, "-please select item-", new { className = "unselected" })%> </td> <td><%= Html.ValidationMessage("cat.parent_id")%> </td> </tr> <% if (Session["TempFolder"] == null) { for (int i = 1; i < 6; i++) { %> <tr> <td> <%=Html.Label("Shot "+i.ToString()) %> </td> <td><input type="file" id="image_<%= i.ToString() %>" name="image_<%= i.ToString() %>" /></td> </tr> <% } }%> <tr> <td><input type="submit" value="save"/></td> </tr> </table> </form> </div>

  • Windows 2003 print services for unix causing CUPS "lpd_command returning 1"

    - by Stephen P. Schaefer
    We have several Windows 2003 servers with print services for Unix on them, and which allow Linux machines running CUPS to use printers defined to CUPS with the URI lpd://printer_server/printer_queue_name - they work. An attempt to provide different printers on a different Windows 2003 server with print services for Unix newly enabled causes CUPS to behave like this: a newly defined printer will be in state "Idle". An attempt to print causes CUPS to change the printer state to "Disabled".

Since my Linux boxes can print to other printers via other Windows 2003 print spoolers, I'm wondering what obscure Windows component could be causing this. I don't think it is Windows firewall, since nmap sees the lpd port (515) open on the server. telnet to the server at port 515 declares Connected to server.internal.example.com (10.22.33.44). Escape character is '^]' Connection closed by foreign host. Windows clients successfully print to the CIFS/SMB share of the hp755cm_ps printer. What other reasons are there for Windows to refuse an lpd request?

  • Print jobs sent to server OK, but then get deleted

    - by Paul Morrison
    I have 2 HP computers, one running Win XP SP3, one running Win7. I have a Lexmark X4270 All-in-One printer attached to the Win7 machine via a USB port. I can print OK from the Win 7 machine, but when I print from the WinXP machine, the print job shows up in both print queues (showing the same number of bytes - which is good!), but then the status gets changed to "Deleting - Sent to printer", and that status shows up in both print queues. The print job then stays there until I do a cancel, followed by a system restart. FWIW the owner is shown as Guest, but I have permission for Everyone set to print... I believe I have up-to-date drivers; I don't believe it's a firewall problem. What I would like to see is the Win7 machine's reason for deleting my print jobs - is there a diagnostic tool available? Also, I notice that the port for this printer on the WinXP machine is set to USB001 - I would have thought something like \servername\sharedprinter would be more appropriate - and I can see that in the list of ports, but the system doesn't let me change the port name from USB001... Could someone shed some light? I have spent hours on this! TIA BTW I can do file sharing, no problem!

  • eee box "drobpox" server 24/7

    - by microspino
    I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have a Samsung A4 small laser printer, a HP500 Designjet Plotter, a Samsung Multifunction Machine (fax/print/scan/copy), a modern HP color A3 Deskjet printer and a HP laserjet A4 color printer. All of them need to be connected to this mini server. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: - If You have something similar running for a long time - If You disagree with this hardware choice and If You would suggest some other device. - If You see any issues with my printing setup - Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

  • Error when connecting to shared Windows Printers

    - by TrueDuality
    I'm replacing our Windows 2003 print server with one running on Windows 2008 R2. I have connected and configured all of our printers and can successfully print to them from the server itself. All of the printers are shared and user's have permission to print on all of them. Whenever one of our clients attempts to connect through the shares they receive the following error message: Operation could not be completed (error 0x0000709). Double check the printer name and make sure that the printer is connected to the network. No messages are generated on the client Event Log nor is anything generated on the server. I have reinstalled the drivers as suggested by a few forum posts I came across and it didn't solve the issue. There are twelve different printer drivers and they are all experiencing this issue so I believe it is unrelated to the driver. I have disabled UAC on both the client and server since that has caused so many headaches before, but it too did not solve this problem. Does anyone have any idea what may be causing this?

  • (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

    - by JohnB
    I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful. I don't like to create multiple threads on multiple sites, but I'm posting here due to Chopper3's suggestion on my post on ServerFault (http://serverfault.com/questions/135349/mac-intel-hp-ps-driver-prints-in-bw-from-adobe-reader-after-installing-cannon)

  • Window 7 Host does not answer to ping

    - by gencha
    Today I tried printing on a shared printer on one of our homegroup members. Sadly it did not work (printer marked as offline). Shortly after, I noticed I can't even ping the machine that owns the printer (I also can not remotely access it in any other way I've tried). Currently I'm trying to ping the machine from the router both computers are connected to (and my machine in question doesn't answer). I do receive the echo requests (as verified with WireShark). I also added a rule in the Windows Firewall to specifically allow ICMP echo requests, but that didn't change anything. I also tried netsh firewall set icmpsetting 8 enable, but that didn't change anything either. Completely disabling the Windows Firewall has no effect on the issue either. One has to wonder, where does Windows log when and why it ignored any incoming packets? How can I get to the bottom of this? Here are some ways I found to dig deeper into the issue: Enabling logging on the Windows Firewall Enabling Windows Filtering Platform Auditing Both methods at least give more insight into the issue. The plain log file is full of entries like this: 2011-11-11 14:35:27 DROP ICMP 192.168.133.1 192.168.133.128 - - 84 - - - - 8 0 - RECEIVE So the ICMP packets are being dropped as if that was intended. The Event Viewer now gives a little bit more details: The Windows Filtering Platform has blocked a packet. Application Information: Process ID: 4 Application Name: System Network Information: Direction: Inbound Source Address: 192.168.133.1 Source Port: 0 Destination Address: 192.168.133.128 Destination Port: 8 Protocol: 1 Filter Information: Filter Run-Time ID: 214517 Layer Name: Receive/Accept Layer Run-Time ID: 44 This same entry is always repeated with 2 points of information changing: Process ID: 420 Application Name: \device\harddiskvolume2\windows\system32\svchost.exe The service host with the PID 420 is the host for the following services: Windows Audio DHCP Client Windows Event Log HomeGroup Provider TCP/IP NetBIOS Helper Security Center Additionally, there is currently this problem with the same machine: Even though my network is set to be a "Home network", I am unable to create a new homegroup.

  • Mac OS X duplex printing problem: one- vs. multi-paged documents

    - by Christian Lindig
    I like to print on pre-printed stationery using the Preview.app and a duplex-capable HP Color Laserjet 4700 (PostScript) printer. The print dialog handles one and two-paged documents differently: the paper needs to be placed differently into the tray if the document contains one page versus when it contains two pages. This is not obvious when printing on plain paper but becomes obvious when front and reverse side of sheets are marked. Otherwise the first page would end up on the reverse side of the first sheet. I believe the problem is caused by the printer driver setting duplex printing to false (using the PostScript setpagedevice operator) when emitting a single-page document versus keeping it set to true when emitting multi-page documents. All this despite that duplex printing is always specified in the printer dialog. When printing a single-sided document, duplex=true and duplex=false seem to make a difference with respect which side of a sheet gets printed on. It would be also helpful if others could confirm the problem actually exists. I suspect this problem is not limited to specific printers. I'm on OS X 10.6 and I checked two different HP printers.

  • Can't open shared drive after disconnecting vpn

    - by Matt McMinn
    I use a VPN to connect to my office network. On my local network I have another WinXP machine that shares a printer and a few shared folders. While I'm connected to my work VPN, I can access the shared printer and folders on the other machine just fine, and vice versa. Once I disconnect the VPN, I can't access the local machine any more, and the other machine can't access my machine. The network itself seems ok - I can ping the other machine, get to the internet, and get on to a web server shared by the other machine, but I can't get to the shared folders or printer. If I reconnect to the VPN, my access is restored. I'm guessing this is some sort of authentication thing, but I don't know what. Any ideas? Update This problem is bothering me again, so here's an update. Depending on when I first access the WinXP machine, I either have this problem, or the opposite problem. After a reboot, if I (for example) print, then connect to the VPN, I can't access the machine while on the VPN. If after a reboot I connect to the VPN, then print, I can't access the machine off the VPN. In both cases, if I enable/disable the VPN again, I can access the machine again. Thanks

  • PyML 0.7.2 - How to prevent accuracy from dropping after storing/loading a classifier?

    - by Michael Aaron Safyan
    This is a followup from "Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?". The solution to that question was close, but not quite right, (the SparseDataSet is broken, so attempting to save/load with that dataset container type will fail, no matter what. Also, PyML is inconsistent in terms of whether labels should be numbers or strings... it turns out that the oneAgainstRest function is actually not good enough, because the labels need to be strings and simultaneously convertible to floats, because there are places where it is assumed to be a string and elsewhere converted to float) and so after a great deal of hacking and such I was finally able to figure out a way to save and load my multi-class classifier without it blowing up with an error.... however, although it is no longer giving me an error message, it is still not quite right as the accuracy of the classifier drops significantly when it is saved and then reloaded (so I'm still missing a piece of the puzzle). I am currently using the following custom mutli-class classifier for training, saving, and loading: class SVM(object): def __init__(self,features_or_filename,labels=None,kernel=None): if isinstance(features_or_filename,str): filename=features_or_filename; if labels!=None: raise ValueError,"Labels must be None if loading from a file."; with open(os.path.join(filename,"uniquelabels.list"),"rb") as uniquelabelsfile: self.uniquelabels=sorted(list(set(pickle.load(uniquelabelsfile)))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; self.classifiers=[]; for classidx, classname in enumerate(self.uniquelabels): self.classifiers.append(PyML.classifiers.svm.loadSVM(os.path.join(filename,str(classname)+".pyml.svm"),datasetClass = PyML.VectorDataSet)); else: features=features_or_filename; if labels==None: raise ValueError,"Labels must not be None when training."; self.uniquelabels=sorted(list(set(labels))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; points = [[float(xij) for xij in xi] for xi in features]; self.classifiers=[PyML.SVM(kernel) for label in self.uniquelabels]; for i in xrange(len(self.uniquelabels)): currentlabel=self.uniquelabels[i]; currentlabels=['+1' if k==currentlabel else '-1' for k in labels]; currentdataset=PyML.VectorDataSet(points,L=currentlabels,positiveClass='+1'); self.classifiers[i].train(currentdataset,saveSpace=False); def accuracy(self,pts,labels): logger=logging.getLogger("ml"); correct=0; total=0; classindexes=[self.labeltoindex[label] for label in labels]; h=self.hypotheses(pts); for idx in xrange(len(pts)): if h[idx]==classindexes[idx]: logger.info("RIGHT: Actual \"%s\" == Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])); correct+=1; else: logger.info("WRONG: Actual \"%s\" != Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])) total+=1; return float(correct)/float(total); def prediction(self,pt): h=self.hypothesis(pt); if h!=None: return self.uniquelabels[h]; return h; def predictions(self,pts): h=self.hypotheses(self,pts); return [self.uniquelabels[x] if x!=None else None for x in h]; def hypothesis(self,pt): bestvalue=None; bestclass=None; dataset=PyML.VectorDataSet([pt]); for classidx, classifier in enumerate(self.classifiers): val=classifier.decisionFunc(dataset,0); if (bestvalue==None) or (val>bestvalue): bestvalue=val; bestclass=classidx; return bestclass; def hypotheses(self,pts): bestvalues=[None for pt in pts]; bestclasses=[None for pt in pts]; dataset=PyML.VectorDataSet(pts); for classidx, classifier in enumerate(self.classifiers): for ptidx in xrange(len(pts)): val=classifier.decisionFunc(dataset,ptidx); if (bestvalues[ptidx]==None) or (val>bestvalues[ptidx]): bestvalues[ptidx]=val; bestclasses[ptidx]=classidx; return bestclasses; def save(self,filename): if not os.path.exists(filename): os.makedirs(filename); with open(os.path.join(filename,"uniquelabels.list"),"wb") as uniquelabelsfile: pickle.dump(self.uniquelabels,uniquelabelsfile,pickle.HIGHEST_PROTOCOL); for classidx, classname in enumerate(self.uniquelabels): self.classifiers[classidx].save(os.path.join(filename,str(classname)+".pyml.svm")); I am using the latest version of PyML (0.7.2, although PyML.__version__ is 0.7.0). When I construct the classifier with a training dataset, the reported accuracy is ~0.87. When I then save it and reload it, the accuracy is less than 0.001. So, there is something here that I am clearly not persisting correctly, although what that may be is completely non-obvious to me. Would you happen to know what that is?

I have placed one textbox(txtPassword) and one button(btnLogin) control in the Div which will be shown by the jQueryDialog.But in btnLogin's Click event, I am not able to read the Text value entered in the textbox txtPassword The below is my code <form id="form1" runat="server"> <div> <br /> <asp:TextBox ID="txtModelId" runat="server" Text=""></asp:TextBox><br /> <asp:Button ID="btnGo" runat="server" Text="Go" OnClick="btnGo_Click" /> <br /> <asp:Label ID="lblUserMsg" runat="server" Text="Label"></asp:Label></div> <div id="divContentHolder"> <div class="demo"> <div id="dialog" title="Login with your TradeIn Account"> <p id="validateTips">Enter your EmailId & password</p> <fieldset> <label for="email">Email</label> <asp:TextBox ID="txtEmail" CssClass="text ui-widget-content ui-corner-all" runat="server" ></asp:TextBox> <label for="password"> <asp:TextBox ID="TextBox1" runat="server" Text="sample"></asp:TextBox>Password</label> <asp:TextBox ID="txtPassword" CssClass="text ui-widget-content ui-corner-all" runat="server" ></asp:TextBox> <asp:Button ID="btnLogin" runat="server" Text="Login" OnClick="btnLogin_Click" UseSubmitBehavior="false"/> </fieldset> </div><!--dialog--> </div><!--demo--> </div><!--divContentHolder--> </form> Server side Code protected void btnGo_Click(object sender, EventArgs e) { CheckUserLoggedIn(); } private void CheckUserLoggedIn() { if (Session["username"] != null) { Response.Write("Logged in user"); ClientScript.RegisterHiddenField("isAuthenticated", "true"); } else { ClientScript.RegisterHiddenField("isAuthenticated", "false"); } } protected void btnLogin_Click(object sender, EventArgs e) { string txtSample= TextBox1.Text; // this is showing the value 'sample' string txtPass= txtPassword.Text; // this is showing null if (txtPass == "shyju") { Session["username"] = txtPassword.Text; Response.Redirect("TestingModal.aspx"); } } My java script code to render the dialog $(function() { var name = $("#name"), email = $("#email"), password = $("#password"), allFields = $([]).add(name).add(email).add(password), tips = $("#validateTips"); function updateTips(t) { tips.text(t).effect("highlight",{},1500); } function checkLength(o,n,min,max) { if ( o.val().length > max || o.val().length < min ) { o.addClass('ui-state-error'); updateTips("Length of " + n + " must be between "+min+" and "+max+"."); return false; } else { return true; } } function checkRegexp(o,regexp,n) { if ( !( regexp.test( o.val() ) ) ) { o.addClass('ui-state-error'); updateTips(n); return false; } else { return true; } } $("#dialog").dialog({ bgiframe: true, autoOpen: false, height: 300, modal: true, buttons: { 'Create an account': function() { var bValid = true; allFields.removeClass('ui-state-error'); bValid=true; if (bValid) { /*$('#users tbody').append('<tr>' + '<td>' + name.val() + '</td>' + '<td>' + email.val() + '</td>' + '<td>' + password.val() + '</td>' + '</tr>'); */ alert("Check User Credentials") $(this).dialog('close'); } }, Cancel: function() { $(this).dialog('close'); } }, close: function() { allFields.val('').removeClass('ui-state-error'); } }); $('#create-user').click(function() { $('#dialog').dialog('open'); }) .hover( function(){ $(this).addClass("ui-state-hover"); }, function(){ $(this).removeClass("ui-state-hover"); } ).mousedown(function(){ $(this).addClass("ui-state-active"); }) .mouseup(function(){ $(this).removeClass("ui-state-active"); }); var isAuthenticated = $("#isAuthenticated").val(); if (isAuthenticated && isAuthenticated == "false") { // Display the modal dialog. $("#dialog").dialog("open"); } }); I had hard coded the text properties value of TextBox1 as 'sample' in the HTML part of my ASPX file .In button click event i am getting it.But the other textbox,txtPassword 's Text property is giving me null value Please guide me to go ahead Thanks in advance

  • PyML 0.7.2 - How to prevent accuracy from dropping after stroing/loading a classifier?

    - by Michael Aaron Safyan
    This is a followup from "Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?". The solution to that question was close, but not quite right, (the SparseDataSet is broken, so attempting to save/load with that dataset container type will fail, no matter what. Also, PyML is inconsistent in terms of whether labels should be numbers or strings... it turns out that the oneAgainstRest function is actually not good enough, because the labels need to be strings and simultaneously convertible to floats, because there are places where it is assumed to be a string and elsewhere converted to float) and so after a great deal of hacking and such I was finally able to figure out a way to save and load my multi-class classifier without it blowing up with an error.... however, although it is no longer giving me an error message, it is still not quite right as the accuracy of the classifier drops significantly when it is saved and then reloaded (so I'm still missing a piece of the puzzle). I am currently using the following custom mutli-class classifier for training, saving, and loading: class SVM(object): def __init__(self,features_or_filename,labels=None,kernel=None): if isinstance(features_or_filename,str): filename=features_or_filename; if labels!=None: raise ValueError,"Labels must be None if loading from a file."; with open(os.path.join(filename,"uniquelabels.list"),"rb") as uniquelabelsfile: self.uniquelabels=sorted(list(set(pickle.load(uniquelabelsfile)))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; self.classifiers=[]; for classidx, classname in enumerate(self.uniquelabels): self.classifiers.append(PyML.classifiers.svm.loadSVM(os.path.join(filename,str(classname)+".pyml.svm"),datasetClass = PyML.VectorDataSet)); else: features=features_or_filename; if labels==None: raise ValueError,"Labels must not be None when training."; self.uniquelabels=sorted(list(set(labels))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; points = [[float(xij) for xij in xi] for xi in features]; self.classifiers=[PyML.SVM(kernel) for label in self.uniquelabels]; for i in xrange(len(self.uniquelabels)): currentlabel=self.uniquelabels[i]; currentlabels=['+1' if k==currentlabel else '-1' for k in labels]; currentdataset=PyML.VectorDataSet(points,L=currentlabels,positiveClass='+1'); self.classifiers[i].train(currentdataset,saveSpace=False); def accuracy(self,pts,labels): logger=logging.getLogger("ml"); correct=0; total=0; classindexes=[self.labeltoindex[label] for label in labels]; h=self.hypotheses(pts); for idx in xrange(len(pts)): if h[idx]==classindexes[idx]: logger.info("RIGHT: Actual \"%s\" == Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])); correct+=1; else: logger.info("WRONG: Actual \"%s\" != Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])) total+=1; return float(correct)/float(total); def prediction(self,pt): h=self.hypothesis(pt); if h!=None: return self.uniquelabels[h]; return h; def predictions(self,pts): h=self.hypotheses(self,pts); return [self.uniquelabels[x] if x!=None else None for x in h]; def hypothesis(self,pt): bestvalue=None; bestclass=None; dataset=PyML.VectorDataSet([pt]); for classidx, classifier in enumerate(self.classifiers): val=classifier.decisionFunc(dataset,0); if (bestvalue==None) or (val>bestvalue): bestvalue=val; bestclass=classidx; return bestclass; def hypotheses(self,pts): bestvalues=[None for pt in pts]; bestclasses=[None for pt in pts]; dataset=PyML.VectorDataSet(pts); for classidx, classifier in enumerate(self.classifiers): for ptidx in xrange(len(pts)): val=classifier.decisionFunc(dataset,ptidx); if (bestvalues[ptidx]==None) or (val>bestvalues[ptidx]): bestvalues[ptidx]=val; bestclasses[ptidx]=classidx; return bestclasses; def save(self,filename): if not os.path.exists(filename): os.makedirs(filename); with open(os.path.join(filename,"uniquelabels.list"),"wb") as uniquelabelsfile: pickle.dump(self.uniquelabels,uniquelabelsfile,pickle.HIGHEST_PROTOCOL); for classidx, classname in enumerate(self.uniquelabels): self.classifiers[classidx].save(os.path.join(filename,str(classname)+".pyml.svm")); I am using the latest version of PyML (0.7.2, although PyML.__version__ is 0.7.0). When I construct the classifier with a training dataset, the reported accuracy is ~0.87. When I then save it and reload it, the accuracy is less than 0.001. So, there is something here that I am clearly not persisting correctly, although what that may be is completely non-obvious to me. Would you happen to know what that is?

  • Nested form problem in Rails : NoMethodError in Show

    - by brianheys
    I'm trying to build a simple product backlog application to teach myself Rails. For each product, there can be multiple product backlog entries, so I want to create a product view that shows the product information, all the backlog entries for the product, and includes a nested form for adding more backlog entries. Everything works until I try to add the form to the view, which then results in the following error: NoMethodError in Products#show Showing app/views/products/show.html.erb where line #29 raised: undefined method `pblog_ref' for #<Product:0x10423ba68> Extracted source (around line #29): 26: <%= f.error_messages %> 27: <p> 28: <%= f.label :pblog_ref %><br /> 29: <%= f.text_field :pblog_ref %> 30: </p> 31: <p> 32: <%= f.label :product %><br /> The product view where the problem is reported is as follows (the partial works fine, so I won't include that code): <h1>Showing product</h1> <p> <b>Product ref:</b> <%=h @product.product_ref %> </p> <p> <b>Description:</b> <%=h @product.description %> </p> <p> <b>Owner:</b> <%=h @product.owner %> </p> <p> <b>Status:</b> <%=h @product.status %> </p> <h2>Product backlog</h2> <div id="product-backlog"> <%= render :partial => @product.product_backlogs %> </div> <% form_for(@product, ProductBacklog.new) do |f| %> <%= f.error_messages %> <p> <%= f.label :pblog_ref %><br /> <%= f.text_field :pblog_ref %> </p> <p> <%= f.label :product %><br /> <%= f.text_field :product %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :owner %><br /> <%= f.text_field :owner %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Edit', edit_product_path(@product) %> | <%= link_to 'Back', products_path %> This is the Product model: class Product < ActiveRecord::Base validates_presence_of :product_ref, :description, :owner has_many :product_backlogs end This is the ProductBacklog model: class ProductBacklog < ActiveRecord::Base belongs_to :product end These are the routes: map.resources :product_backlogs map.resources :products, :has_many => :product_backlogs I've checked what I'm doing against the Creating a weblog in 15 minutes with Rails 2 screencast, and in principle I seem to be doing the same thing as him - only his nested comments form works, and mine doesn't! I hope someone can help with this, before I turn mad! I'm sure it's something trivial.

  • Building applications with WPF, MVVM and Prism(aka CAG)

    - by skjagini
    In this article I am going to walk through an application using WPF and Prism (aka composite application guidance, CAG) which simulates engaging a taxi (cab).  The rules are simple, the app would have3 screens A login screen to authenticate the user An information screen. A screen to engage the cab and roam around and calculating the total fare Metered Rate of Fare The meter is required to be engaged when a cab is occupied by anyone $3.00 upon entry $0.35 for each additional unit The unit fare is: one-fifth of a mile, when the cab is traveling at 6 miles an hour or more; or 60 seconds when not in motion or traveling at less than 12 miles per hour. Night surcharge of $.50 after 8:00 PM & before 6:00 AM Peak hour Weekday Surcharge of $1.00 Monday - Friday after 4:00 PM & before 8:00 PM New York State Tax Surcharge of $.50 per ride. Example: Friday (2010-10-08) 5:30pm Start at Lexington Ave & E 57th St End at Irving Pl & E 15th St Start = $3.00 Travels 2 miles at less than 6 mph for 15 minutes = $3.50 Travels at more than 12 mph for 5 minutes = $1.75 Peak hour Weekday Surcharge = $1.00 (ride started at 5:30 pm) New York State Tax Surcharge = $0.50 Before we dive into the app, I would like to give brief description about the framework.  If you want to jump on to the source code, scroll all the way to the end of the post. MVVM MVVM pattern is in no way related to the usage of PRISM in your application and should be considered if you are using WPF irrespective of PRISM or not. Lets say you are not familiar with MVVM, your typical UI would involve adding some UI controls like text boxes, a button, double clicking on the button,  generating event handler, calling a method from business layer and updating the user interface, it works most of the time for developing small scale applications. The problem with this approach is that there is some amount of code specific to business logic wrapped in UI specific code which is hard to unit test it, mock it and MVVM helps to solve the exact problem. MVVM stands for Model(M) – View(V) – ViewModel(VM),  based on the interactions with in the three parties it should be called VVMM,  MVVM sounds more like MVC (Model-View-Controller) so the name. Why it should be called VVMM: View – View Model - Model WPF allows to create user interfaces using XAML and MVVM takes it to the next level by allowing complete separation of user interface and business logic. In WPF each view will have a property, DataContext when set to an instance of a class (which happens to be your view model) provides the data the view is interested in, i.e., view interacts with view model and at the same time view model interacts with view through DataContext. Sujith, if view and view model are interacting directly with each other how does MVVM is helping me separation of concerns? Well, the catch is DataContext is of type Object, since it is of type object view doesn’t know exact type of view model allowing views and views models to be loosely coupled. View models aggregate data from models (data access layer, services, etc) and make it available for views through properties, methods etc, i.e., View Models interact with Models. PRISM Prism is provided by Microsoft Patterns and Practices team and it can be downloaded from codeplex for source code,  samples and documentation on msdn.  The name composite implies, to compose user interface from different modules (views) without direct dependencies on each other, again allowing  loosely coupled development. Well Sujith, I can already do that with user controls, why shall I learn another framework?  That’s correct, you can decouple using user controls, but you still have to manage some amount of coupling, like how to do you communicate between the controls, how do you subscribe/unsubscribe, loading/unloading views dynamically. Prism is not a replacement for user controls, provides the following features which greatly help in designing the composite applications. Dependency Injection (DI)/ Inversion of Control (IoC) Modules Regions Event Aggregator  Commands Simply put, MVVM helps building a single view and Prism helps building an application using the views There are other open source alternatives to Prism, like MVVMLight, Cinch, take a look at them as well. Lets dig into the source code.  1. Solution The solution is made of the following projects Framework: Holds the common functionality in building applications using WPF and Prism TaxiClient: Start up project, boot strapping and app styling TaxiCommon: Helps with the business logic TaxiModules: Holds the meat of the application with views and view models TaxiTests: To test the application 2. DI / IoC Dependency Injection (DI) as the name implies refers to injecting dependencies and Inversion of Control (IoC) means the calling code has no direct control on the dependencies, opposite of normal way of programming where dependencies are passed by caller, i.e inversion; aside from some differences in terminology the concept is same in both the cases. The idea behind DI/IoC pattern is to reduce the amount of direct coupling between different components of the application, the higher the dependency the more tightly coupled the application resulting in code which is hard to modify, unit test and mock.  Initializing Dependency Injection through BootStrapper TaxiClient is the starting project of the solution and App (App.xaml)  is the starting class that gets called when you run the application. From the App’s OnStartup method we will invoke BootStrapper.   namespace TaxiClient { /// <summary> /// Interaction logic for App.xaml /// </summary> public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e);   (new BootStrapper()).Run(); } } } BootStrapper is your contact point for initializing the application including dependency injection, creating Shell and other frameworks. We are going to use Unity for DI and there are lot of open source DI frameworks like Spring.Net, StructureMap etc with different feature set  and you can choose a framework based on your preferences. Note that Prism comes with in built support for Unity, for example we are deriving from UnityBootStrapper in our case and for any other DI framework you have to extend the Prism appropriately   namespace TaxiClient { public class BootStrapper: UnityBootstrapper { protected override IModuleCatalog CreateModuleCatalog() { return new ConfigurationModuleCatalog(); } protected override DependencyObject CreateShell() { Framework.FrameworkBootStrapper.Run(Container, Application.Current.Dispatcher);   Shell shell = new Shell(); shell.ResizeMode = ResizeMode.NoResize; shell.Show();   return shell; } } } Lets take a look into  FrameworkBootStrapper to check out how to register with unity container. namespace Framework { public class FrameworkBootStrapper { public static void Run(IUnityContainer container, Dispatcher dispatcher) { UIDispatcher uiDispatcher = new UIDispatcher(dispatcher); container.RegisterInstance<IDispatcherService>(uiDispatcher);   container.RegisterType<IInjectSingleViewService, InjectSingleViewService>( new ContainerControlledLifetimeManager());   . . . } } } In the above code we are registering two components with unity container. You shall observe that we are following two different approaches, RegisterInstance and RegisterType.  With RegisterInstance we are registering an existing instance and the same instance will be returned for every request made for IDispatcherService   and with RegisterType we are requesting unity container to create an instance for us when required, i.e., when I request for an instance for IInjectSingleViewService, unity will create/return an instance of InjectSingleViewService class and with RegisterType we can configure the life time of the instance being created. With ContaienrControllerLifetimeManager, the unity container caches the instance and reuses for any subsequent requests, without recreating a new instance. Lets take a look into FareViewModel.cs and it’s constructor. The constructor takes one parameter IEventAggregator and if you try to find all references in your solution for IEventAggregator, you will not find a single location where an instance of EventAggregator is passed directly to the constructor. The compiler still finds an instance and works fine because Prism is already configured when used with Unity container to return an instance of EventAggregator when requested for IEventAggregator and in this particular case it is called constructor injection. public class FareViewModel:ObservableBase, IDataErrorInfo { ... private IEventAggregator _eventAggregator;   public FareViewModel(IEventAggregator eventAggregator) { _eventAggregator = eventAggregator; InitializePropertyNames(); InitializeModel(); PropertyChanged += OnPropertyChanged; } ... 3. Shell Shells are very similar in operation to Master Pages in asp.net or MDI in Windows Forms. And shells contain regions which display the views, you can have as many regions as you wish in a given view. You can also nest regions. i.e, one region can load a view which in itself may contain other regions. We have to create a shell at the start of the application and are doing it by overriding CreateShell method from BootStrapper From the following Shell.xaml you shall notice that we have two content controls with Region names as ‘MenuRegion’ and ‘MainRegion’.  The idea here is that you can inject any user controls into the regions dynamically, i.e., a Menu User Control for MenuRegion and based on the user action you can load appropriate view into MainRegion.    <Window x:Class="TaxiClient.Shell" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Regions="clr-namespace:Microsoft.Practices.Prism.Regions;assembly=Microsoft.Practices.Prism" Title="Taxi" Height="370" Width="800"> <Grid Margin="2"> <ContentControl Regions:RegionManager.RegionName="MenuRegion" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" />   <ContentControl Grid.Row="1" Regions:RegionManager.RegionName="MainRegion" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" /> <!--<Border Grid.ColumnSpan="2" BorderThickness="2" CornerRadius="3" BorderBrush="LightBlue" />-->   </Grid> </Window> 4. Modules Prism provides the ability to build composite applications and modules play an important role in it. For example if you are building a Mortgage Loan Processor application with 3 components, i.e. customer’s credit history,  existing mortgages, new home/loan information; and consider that the customer’s credit history component involves gathering data about his/her address, background information, job details etc. The idea here using Prism modules is to separate the implementation of these 3 components into their own visual studio projects allowing to build components with no dependency on each other and independently. If we need to add another component to the application, the component can be developed by in house team or some other team in the organization by starting with a new Visual Studio project and adding to the solution at the run time with very little knowledge about the application. Prism modules are defined by implementing the IModule interface and each visual studio project to be considered as a module should implement the IModule interface.  From the BootStrapper.cs you shall observe that we are overriding the method by returning a ConfiguratingModuleCatalog which returns the modules that are registered for the application using the app.config file  and you can also add module using code. Lets take a look into configuration file.   <?xml version="1.0"?> <configuration> <configSections> <section name="modules" type="Microsoft.Practices.Prism.Modularity.ModulesConfigurationSection, Microsoft.Practices.Prism"/> </configSections> <modules> <module assemblyFile="TaxiModules.dll" moduleType="TaxiModules.ModuleInitializer, TaxiModules" moduleName="TaxiModules"/> </modules> </configuration> Here we are adding TaxiModules project to our solution and TaxiModules.ModuleInitializer implements IModule interface   5. Module Mapper With Prism modules you can dynamically add or remove modules from the regions, apart from that Prism also provides API to control adding/removing the views from a region within the same module. Taxi Information Screen: Engage the Taxi Screen: The sample application has two screens, ‘Taxi Information’ and ‘Engage the Taxi’ and they both reside in same module, TaxiModules. ‘Engage the Taxi’ is again made of two user controls, FareView on the left and TotalView on the right. We have created a Shell with two regions, MenuRegion and MainRegion with menu loaded into MenuRegion. We can create a wrapper user control called EngageTheTaxi made of FareView and TotalView and load either TaxiInfo or EngageTheTaxi into MainRegion based on the user action. Though it will work it tightly binds the user controls and for every combination of user controls, we need to create a dummy wrapper control to contain them. Instead we can apply the principles we learned so far from Shell/regions and introduce another template (LeftAndRightRegionView.xaml) made of two regions Region1 (left) and Region2 (right) and load  FareView and TotalView dynamically.  To help with loading of the views dynamically I have introduce an helper an interface, IInjectSingleViewService,  idea suggested by Mike Taulty, a must read blog for .Net developers. using System; using System.Collections.Generic; using System.ComponentModel;   namespace Framework.PresentationUtility.Navigation {   public interface IInjectSingleViewService : INotifyPropertyChanged { IEnumerable<CommandViewDefinition> Commands { get; } IEnumerable<ModuleViewDefinition> Modules { get; }   void RegisterViewForRegion(string commandName, string viewName, string regionName, Type viewType); void ClearViewFromRegion(string viewName, string regionName); void RegisterModule(string moduleName, IList<ModuleMapper> moduleMappers); } } The Interface declares three methods to work with views: RegisterViewForRegion: Registers a view with a particular region. You can register multiple views and their regions under one command.  When this particular command is invoked all the views registered under it will be loaded into their regions. ClearViewFromRegion: To unload a specific view from a region. RegisterModule: The idea is when a command is invoked you can load the UI with set of controls in their default position and based on the user interaction, you can load different contols in to different regions on the fly.  And it is supported ModuleViewDefinition and ModuleMappers as shown below. namespace Framework.PresentationUtility.Navigation { public class ModuleViewDefinition { public string ModuleName { get; set; } public IList<ModuleMapper> ModuleMappers; public ICommand Command { get; set; } }   public class ModuleMapper { public string ViewName { get; set; } public string RegionName { get; set; } public Type ViewType { get; set; } } } 6. Event Aggregator Prism event aggregator enables messaging between components as in Observable pattern, Notifier notifies the Observer which receives notification it is interested in. When it comes to Observable pattern, Observer has to unsubscribes for notifications when it no longer interested in notifications, which allows the Notifier to remove the Observer’s reference from it’s local cache. Though .Net has managed garbage collection it cannot remove inactive the instances referenced by an active instance resulting in memory leak, keeping the Observers in memory as long as Notifier stays in memory.  Developers have to be very careful to unsubscribe when necessary and it often gets overlooked, to overcome these problems Prism Event Aggregator uses weak references to cache the reference (Observer in this case)  and releases the reference (memory) once the instance goes out of scope. Using event aggregator is very simple, declare a generic type of CompositePresenationEvent by inheriting from it. using Microsoft.Practices.Prism.Events; using TaxiCommon.BAO;   namespace TaxiCommon.CompositeEvents { public class TaxiOnMoveEvent:CompositePresentationEvent<TaxiOnMove> { } }   TaxiOnMove.cs includes the properties which we want to exchange between the parties, FareView and TotalView. using System;   namespace TaxiCommon.BAO { public class TaxiOnMove { public TimeSpan MinutesAtTweleveMPH { get; set; } public double MilesAtSixMPH { get; set; } } }   Lets take a look into FareViewodel (Notifier) and how it raises the event.  Here we are raising the event by getting the event through GetEvent<..>() and publishing it with the payload private void OnAddMinutes(object obj) { TaxiOnMove payload = new TaxiOnMove(); if(MilesAtSixMPH != null) payload.MilesAtSixMPH = MilesAtSixMPH.Value; if(MinutesAtTweleveMPH != null) payload.MinutesAtTweleveMPH = new TimeSpan(0,0,MinutesAtTweleveMPH.Value,0);   _eventAggregator.GetEvent<TaxiOnMoveEvent>().Publish(payload); ResetMinutesAndMiles(); } And TotalViewModel(Observer) subscribes to notifications by getting the event through GetEvent<..>() namespace TaxiModules.ViewModels { public class TotalViewModel:ObservableBase { .... private IEventAggregator _eventAggregator;   public TotalViewModel(IEventAggregator eventAggregator) { _eventAggregator = eventAggregator; ... }   private void SubscribeToEvents() { _eventAggregator.GetEvent<TaxiStartedEvent>() .Subscribe(OnTaxiStarted, ThreadOption.UIThread,false,(filter) => true); _eventAggregator.GetEvent<TaxiOnMoveEvent>() .Subscribe(OnTaxiMove, ThreadOption.UIThread, false, (filter) => true); _eventAggregator.GetEvent<TaxiResetEvent>() .Subscribe(OnTaxiReset, ThreadOption.UIThread, false, (filter) => true); }   ... private void OnTaxiMove(TaxiOnMove taxiOnMove) { OnMoveFare fare = new OnMoveFare(taxiOnMove); Fares.Add(fare); SetTotalFare(new []{fare}); }   .... 7. MVVM through example In this section we are going to look into MVVM implementation through example.  I have all the modules declared in a single project, TaxiModules, again it is not necessary to have them into one project. Once the user logs into the application, will be greeted with the ‘Engage the Taxi’ screen which is made of two user controls, FareView.xaml and TotalView.Xaml. As you can see from the solution explorer, each of them have their own code behind files and  ViewModel classes, FareViewMode.cs, TotalViewModel.cs Lets take a look in to the FareView and how it interacts with FareViewModel using MVVM implementation. FareView.xaml acts as a view and FareViewMode.cs is it’s view model. The FareView code behind class   namespace TaxiModules.Views { /// <summary> /// Interaction logic for FareView.xaml /// </summary> public partial class FareView : UserControl { public FareView(FareViewModel viewModel) { InitializeComponent(); this.Loaded += (s, e) => { this.DataContext = viewModel; }; } } } The FareView is bound to FareViewModel through the data context  and you shall observe that DataContext is of type Object, i.e. the FareView doesn’t really know the type of ViewModel (FareViewModel). This helps separation of View and ViewModel as View and ViewModel are independent of each other, you can bind FareView to FareViewModel2 as well and the application compiles just fine. Lets take a look into FareView xaml file  <UserControl x:Class="TaxiModules.Views.FareView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Toolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" xmlns:Commands="clr-namespace:Microsoft.Practices.Prism.Commands;assembly=Microsoft.Practices.Prism"> <Grid Margin="10" > ....   <Border Style="{DynamicResource innerBorder}" Grid.Row="0" Grid.Column="0" Grid.RowSpan="11" Grid.ColumnSpan="2" Panel.ZIndex="1"/>   <Label Grid.Row="0" Content="Engage the Taxi" Style="{DynamicResource innerHeader}"/> <Label Grid.Row="1" Content="Select the State"/> <ComboBox Grid.Row="1" Grid.Column="1" ItemsSource="{Binding States}" Height="auto"> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"/> </DataTemplate> </ComboBox.ItemTemplate> <ComboBox.SelectedItem> <Binding Path="SelectedState" Mode="TwoWay"/> </ComboBox.SelectedItem> </ComboBox> <Label Grid.Row="2" Content="Select the Date of Entry"/> <Toolkit:DatePicker Grid.Row="2" Grid.Column="1" SelectedDate="{Binding DateOfEntry, ValidatesOnDataErrors=true}" /> <Label Grid.Row="3" Content="Enter time 24hr format"/> <TextBox Grid.Row="3" Grid.Column="1" Text="{Binding TimeOfEntry, TargetNullValue=''}"/> <Button Grid.Row="4" Grid.Column="1" Content="Start the Meter" Commands:Click.Command="{Binding StartMeterCommand}" />   <Label Grid.Row="5" Content="Run the Taxi" Style="{DynamicResource innerHeader}"/> <Label Grid.Row="6" Content="Number of Miles &lt;@6mph"/> <TextBox Grid.Row="6" Grid.Column="1" Text="{Binding MilesAtSixMPH, TargetNullValue='', ValidatesOnDataErrors=true}"/> <Label Grid.Row="7" Content="Number of Minutes @12mph"/> <TextBox Grid.Row="7" Grid.Column="1" Text="{Binding MinutesAtTweleveMPH, TargetNullValue=''}"/> <Button Grid.Row="8" Grid.Column="1" Content="Add Minutes and Miles " Commands:Click.Command="{Binding AddMinutesCommand}"/> <Label Grid.Row="9" Content="Other Operations" Style="{DynamicResource innerHeader}"/> <Button Grid.Row="10" Grid.Column="1" Content="Reset the Meter" Commands:Click.Command="{Binding ResetCommand}"/>   </Grid> </UserControl> The highlighted code from the above code shows data binding, for example ComboBox which displays list of states has it’s ItemsSource bound to States property, with DataTemplate bound to Name and SelectedItem  to SelectedState. You might be wondering what are all these properties and how it is able to bind to them.  The answer lies in data context, i.e., when you bound a control, WPF looks for data context on the root object (Grid in this case) and if it can’t find data context it will look into root’s root, i.e. FareView UserControl and it is bound to FareViewModel.  Each of those properties have be declared on the ViewModel for the View to bind correctly. To put simply, View is bound to ViewModel through data context of type object and every control that is bound on the View actually binds to the public property on the ViewModel. Lets look into the ViewModel code (the following code is not an exact copy of FareViewMode.cs, pasted relevant code for this section)   namespace TaxiModules.ViewModels { public class FareViewModel:ObservableBase, IDataErrorInfo { public List<USState> States { get { return USStates.StateList; } }   public USState SelectedState { get { return _selectedState; } set { _selectedState = value; RaisePropertyChanged(_selectedStatePropertyName); } }   public DateTime? DateOfEntry { get { return _dateOfEntry; } set { _dateOfEntry = value; RaisePropertyChanged(_dateOfEntryPropertyName); } }   public TimeSpan? TimeOfEntry { get { return _timeOfEntry; } set { _timeOfEntry = value; RaisePropertyChanged(_timeOfEntryPropertyName); } }   public double? MilesAtSixMPH { get { return _milesAtSixMPH; } set { _milesAtSixMPH = value; RaisePropertyChanged(_distanceAtSixMPHPropertyName); } }   public int? MinutesAtTweleveMPH { get { return _minutesAtTweleveMPH; } set { _minutesAtTweleveMPH = value; RaisePropertyChanged(_minutesAtTweleveMPHPropertyName); } }   public ICommand StartMeterCommand { get { if(_startMeterCommand == null) { _startMeterCommand = new DelegateCommand<object>(OnStartMeter, CanStartMeter); } return _startMeterCommand; } }   public ICommand AddMinutesCommand { get { if(_addMinutesCommand == null) { _addMinutesCommand = new DelegateCommand<object>(OnAddMinutes, CanAddMinutes); } return _addMinutesCommand; } }   public ICommand ResetCommand { get { if(_resetCommand == null) { _resetCommand = new DelegateCommand<object>(OnResetCommand); } return _resetCommand; } }   } private void OnStartMeter(object obj) { _eventAggregator.GetEvent<TaxiStartedEvent>().Publish( new TaxiStarted() { EngagedOn = DateOfEntry.Value.Date + TimeOfEntry.Value, EngagedState = SelectedState.Value });   _isMeterStarted = true; OnPropertyChanged(this,null); } And views communicate user actions like button clicks, tree view item selections, etc using commands. When user clicks on ‘Start the Meter’ button it invokes the method StartMeterCommand, which calls the method OnStartMeter which publishes the event to TotalViewModel using event aggregator  and TaxiStartedEvent. namespace TaxiModules.ViewModels { public class TotalViewModel:ObservableBase { ... private IEventAggregator _eventAggregator;   public TotalViewModel(IEventAggregator eventAggregator) { _eventAggregator = eventAggregator;   InitializePropertyNames(); InitializeModel(); SubscribeToEvents(); }   public decimal? TotalFare { get { return _totalFare; } set { _totalFare = value; RaisePropertyChanged(_totalFarePropertyName); } } .... private void SubscribeToEvents() { _eventAggregator.GetEvent<TaxiStartedEvent>().Subscribe(OnTaxiStarted, ThreadOption.UIThread,false,(filter) => true); _eventAggregator.GetEvent<TaxiOnMoveEvent>().Subscribe(OnTaxiMove, ThreadOption.UIThread, false, (filter) => true); _eventAggregator.GetEvent<TaxiResetEvent>().Subscribe(OnTaxiReset, ThreadOption.UIThread, false, (filter) => true); }   private void OnTaxiStarted(TaxiStarted taxiStarted) { Fares.Add(new EntryFare()); Fares.Add(new StateTaxFare(taxiStarted)); Fares.Add(new NightSurchargeFare(taxiStarted)); Fares.Add(new PeakHourWeekdayFare(taxiStarted));   SetTotalFare(Fares); }   private void SetTotalFare(IEnumerable<IFare> fares) { TotalFare = (_totalFare ?? 0) + TaxiFareHelper.GetTotalFare(fares); } ....   } }   TotalViewModel subscribes to events, TaxiStartedEvent and rest. When TaxiStartedEvent gets invoked it calls the OnTaxiStarted method which sets the total fare which includes entry fee, state tax, nightly surcharge, peak hour weekday fare.   Note that TotalViewModel derives from ObservableBase which implements the method RaisePropertyChanged which we are invoking in Set of TotalFare property, i.e, once we update the TotalFare property it raises an the event that  allows the TotalFare text box to fetch the new value through the data context. ViewModel is communicating with View through data context and it has no knowledge about View, helping in loose coupling of ViewModel and View.   I have attached the source code (.Net 4.0, Prism 4.0, VS 2010) , download and play with it and don’t forget to leave your comments.

  • Web Browser Control &ndash; Specifying the IE Version

    - by Rick Strahl
    I use the Internet Explorer Web Browser Control in a lot of my applications to display document type layout. HTML happens to be one of the most common document formats and displaying data in this format – even in desktop applications, is often way easier than using normal desktop technologies. One issue the Web Browser Control has that it’s perpetually stuck in IE 7 rendering mode by default. Even though IE 8 and now 9 have significantly upgraded the IE rendering engine to be more CSS and HTML compliant by default the Web Browser control will have none of it. IE 9 in particular – with its much improved CSS support and basic HTML 5 support is a big improvement and even though the IE control uses some of IE’s internal rendering technology it’s still stuck in the old IE 7 rendering by default. This applies whether you’re using the Web Browser control in a WPF application, a WinForms app, a FoxPro or VB classic application using the ActiveX control. Behind the scenes all these UI platforms use the COM interfaces and so you’re stuck by those same rules. Rendering Challenged To see what I’m talking about here are two screen shots rendering an HTML 5 doctype page that includes some CSS 3 functionality – rounded corners and border shadows - from an earlier post. One uses IE 9 as a standalone browser, and one uses a simple WPF form that includes the Web Browser control. IE 9 Browser:   Web Browser control in a WPF form: The IE 9 page displays this HTML correctly – you see the rounded corners and shadow displayed. Obviously the latter rendering using the Web Browser control in a WPF application is a bit lacking. Not only are the new CSS features missing but the page also renders in Internet Explorer’s quirks mode so all the margins, padding etc. behave differently by default, even though there’s a CSS reset applied on this page. If you’re building an application that intends to use the Web Browser control for a live preview of some HTML this is clearly undesirable. Feature Delegation via Registry Hacks Fortunately starting with Internet Explore 8 and later there’s a fix for this problem via a registry setting. You can specify a registry key to specify which rendering mode and version of IE should be used by that application. These are not global mind you – they have to be enabled for each application individually. There are two different sets of keys for 32 bit and 64 bit applications. 32 bit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION Value Key: yourapplication.exe 64 bit: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION Value Key: yourapplication.exe The value to set this key to is (taken from MSDN here) as decimal values: 9999 (0x270F) Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive. 9000 (0x2328) Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. 8888 (0x22B8) Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive. 8000 (0x1F40) Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. 7000 (0x1B58) Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode.   The added key looks something like this in the Registry Editor: With this in place my Html Html Help Builder application which has wwhelp.exe as its main executable now works with HTML 5 and CSS 3 documents in the same way that Internet Explorer 9 does. Incidentally I accidentally added an ‘empty’ DWORD value of 0 to my EXE name and that worked as well giving me IE 9 rendering. Although not documented I suspect 0 (or an invalid value) will default to the installed browser. Don’t have a good way to test this but if somebody could try this with IE 8 installed that would be great: What happens when setting 9000 with IE 8 installed? What happens when setting 0 with IE 8 installed? Don’t forget to add Keys for Host Environments If you’re developing your application in Visual Studio and you run the debugger you may find that your application is still not rendering right, but if you run the actual generated EXE from Explorer or the OS command prompt it works. That’s because when you run the debugger in Visual Studio it wraps your application into a debugging host container. For this reason you might want to also add another registry key for yourapp.vshost.exe on your development machine. If you’re developing in Visual FoxPro make sure you add a key for vfp9.exe to see the rendering adjustments in the Visual FoxPro development environment. Cleaner HTML - no more HTML mangling! There are a number of additional benefits to setting up rendering of the Web Browser control to the IE 9 engine (or even the IE 8 engine) beyond the obvious rendering functionality. IE 9 actually returns your HTML in something that resembles the original HTML formatting, as opposed to the IE 7 default format which mangled the original HTML content. If you do the following in the WPF application: private void button2_Click(object sender, RoutedEventArgs e) { dynamic doc = this.webBrowser.Document; MessageBox.Show(doc.body.outerHtml); } you get different output depending on the rendering mode active. With the default IE 7 rendering you get: <BODY><DIV> <H1>Rounded Corners and Shadows - Creating Dialogs in CSS</H1> <DIV class=toolbarcontainer><A class=hoverbutton href="./"><IMG src="../../css/images/home.gif"> Home</A> <A class=hoverbutton href="RoundedCornersAndShadows.htm"><IMG src="../../css/images/refresh.gif"> Refresh</A> </DIV> <DIV class=containercontent> <FIELDSET><LEGEND>Plain Box</LEGEND><!-- Simple Box with rounded corners and shadow --> <DIV style="BORDER-BOTTOM: steelblue 2px solid;

                    return true;  // true closes - false leaves open                 }             });     }); </SCRIPT> </DIV></BODY> Now lest you think I’m out of my mind and create complete whacky HTML rooted in the last century, here’s the IE 9 rendering mode output which looks a heck of a lot cleaner and a lot closer to my original HTML of the page I’m accessing: <body> <div>         <h1>Rounded Corners and Shadows - Creating Dialogs in CSS</h1>     <div class="toolbarcontainer">         <a class="hoverbutton" href="./"> <img src="../../css/images/home.gif"> Home</a>         <a class="hoverbutton" href="RoundedCornersAndShadows.htm"> <img src="../../css/images/refresh.gif"> Refresh</a>     </div>         <div class="containercontent">     <fieldset>         <legend>Plain Box</legend>                <!-- Simple Box with rounded corners and shadow -->             <div style="border: 2px solid steelblue;

                    return true;  // true closes - false leaves open                 }             });     }); </script>        </div> </body> IOW, in IE9 rendering mode IE9 is much closer (but not identical) to the original HTML from the page on the Web that we’re reading from. As a side note: Unfortunately, the browser feature emulation can't be applied against the Html Help (CHM) Engine in Windows which uses the Web Browser control (or COM interfaces anyway) to render Html Help content. I tried setting up hh.exe which is the help viewer, to use IE 9 rendering but a help file generated with CSS3 features will simply show in IE 7 mode. Bummer - this would have been a nice quick fix to allow help content served from CHM files to look better. HTML Editing leaves HTML formatting intact In the same vane, if you do any inline HTML editing in the control by setting content to be editable, IE 9’s control does a much more reasonable job of creating usable and somewhat valid HTML. It also leaves the original content alone other than the text your are editing or adding. No longer is the HTML output stripped of excess spaces and reformatted in IEs format. So if I do: private void button3_Click(object sender, RoutedEventArgs e) { dynamic doc = this.webBrowser.Document; doc.body.contentEditable = true; } and then make some changes to the document by typing into it using IE 9 mode, the document formatting stays intact and only the affected content is modified. The created HTML is reasonably clean (although it does lack proper XHTML formatting for things like <br/> <hr/>). This is very different from IE 7 mode which mangled the HTML as soon as the page was loaded into the control. Any editing you did stripped out all white space and lost all of your existing XHTML formatting. In IE 9 mode at least *most* of your original formatting stays intact. This is huge! In Html Help Builder I have supported HTML editing for a long time but the HTML mangling by the Web Browser control made it very difficult to edit the HTML later. Previously IE would mangle the HTML by stripping out spaces, upper casing all tags and converting many XHTML safe tags to its HTML 3 tags. Now IE leaves most of my document alone while editing, and creates cleaner and more compliant markup (with exception of self-closing elements like BR/HR). The end result is that I now have HTML editing in place that's much cleaner and actually capable of being manually edited. Caveats, Caveats, Caveats It wouldn't be Internet Explorer if there weren't some major compatibility issues involved in using this various browser version interaction. The biggest thing I ran into is that there are odd differences in some of the COM interfaces and what they return. I specifically ran into a problem with the document.selection.createRange() function which with IE 7 compatibility returns an expected text range object. When running in IE 8 or IE 9 mode however. I could not retrieve a valid text range with this code where loEdit is the WebBrowser control: loRange = loEdit.document.selection.CreateRange() The loRange object returned (here in FoxPro) had a length property of 0 but none of the other properties of the TextRange or TextRangeCollection objects were available. I figured this was due to some changed security settings but even after elevating the Intranet Security Zone and mucking with the other browser feature flags pertaining to security I had no luck. In the end I relented and used a JavaScript function in my editor document that returns a selection range object: function getselectionrange() { var range = document.selection.createRange(); return range; } and call that JavaScript function from my host applications code: *** Use a function in the document to get around HTML Editing issues loRange = loEdit.document.parentWindow.getselectionrange(.f.) and that does work correctly. This wasn't a big deal as I'm already loading a support script file into the editor page so all I had to do is add the function to this existing script file. You can find out more how to call script code in the Web Browser control from a host application in a previous post of mine. IE 8 and 9 also clamp down the security environment a little more than the default IE 7 control, so there may be other issues you run into. Other than the createRange() problem above I haven't seen anything else that is breaking in my code so far though and that's encouraging at least since it uses a lot of HTML document manipulation for the custom editor I've created (and would love to replace - any PROFESSIONAL alternatives anybody?) Registry Key Installation for your Application It’s important to remember that this registry setting is made per application, so most likely this is something you want to set up with your installer. Also remember that 32 and 64 bit settings require separate settings in the registry so if you’re creating your installer you most likely will want to set both keys in the registry preemptively for your application. I use Tarma Installer for all of my application installs and in Tarma I configure registry keys for both and set a flag to only install the latter key group in the 64 bit version: Because this setting is application specific you have to do this for every application you install unfortunately, but this also means that you can safely configure this setting in the registry because it is after only applied to your application. Another problem with install based installation is version detection. If IE 8 is installed I’d want 8000 for the value, if IE 9 is installed I want 9000. I can do this easily in code but in the installer this is much more difficult. I don’t have a good solution for this at the moment, but given that the app works with IE 7 mode now, IE 9 mode is just a bonus for the moment. If IE 9 is not installed and 9000 is used the default rendering will remain in use.   It sure would be nice if we could specify the IE rendering mode as a property, but I suspect the ActiveX container has to know before it loads what actual version to load up and once loaded can only load a single version of IE. This would account for this annoying application level configuration… Summary The registry feature emulation has been available for quite some time, but I just found out about it today and started experimenting around with it. I’m stoked to see that this is available as I’d pretty much given up in ever seeing any better rendering in the Web Browser control. Now at least my apps can take advantage of newer HTML features. Now if we could only get better HTML Editing support somehow <snicker>… ah can’t have everything.© Rick Strahl, West Wind Technologies, 2005-2011Posted in .NET  FoxPro  Windows

  • Populate google.visualization.DataTable for a AnnotatedTimeLine using JSON

    Hi I have a HttpHandler which returns some JSON in (i think) the correct format for a google.visualization.DataTable, but the AnnotatedTimeLine fails to work? This is the JSON returned by the Handler: {cols: [{id: 'DATE', label: 'Date', type: 'date'}, {id: 'KEYWORD51', label: 'vw cheltenham', type: 'number'}, {id: 'KEYWORD52', label: 'volkswagen cheltenham', type: 'number'}, {id: 'KEYWORD61', label: 'vw dealer cheltenham', type: 'number'}], rows: [{c: [{v: new Date(2010, 3, 13)}, {v: 20}, {v: 1}, {v: 2}]}, {c: [{v: new Date(2010, 3, 14)}, {v: 19}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 15)}, {v: 19}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 16)}, {v: 18}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 17)}, {v: 17}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 18)}, {v: 17}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 19)}, {v: 12}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 20)}, {v: 13}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 21)}, {v: 11}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 22)}, {v: 10}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 23)}, {v: 10}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 24)}, {v: 8}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 25)}, {v: 6}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 26)}, {v: 6}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 27)}, {v: 5}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 28)}, {v: 4}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 29)}, {v: 4}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 30)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 1)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 2)}, {v: 1}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 3)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 4)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 5)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 6)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 7)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 8)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 9)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 10)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 11)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 12)}, {v: 2}, {v: 1}, {v: 1}]}]} This is the Javascript, I used JQuery to get the JSON, have also tried $.getJSON() google.load('visualization', '1', { 'packages': ['annotatedtimeline'] }); google.setOnLoadCallback(loadGraph); function loadGraph() { $.get("/GraphDataHandler.axd", function(response) { drawGraph(response); }); } function drawGraph(response) { var visualization = new google.visualization.AnnotatedTimeLine(document.getElementById('chart_div')); var data = new google.visualization.DataTable(response, 0.6); visualization.draw(data, { title: 'Rankings', titleX: 'Date', titleY: 'Position', displayAnnotations: false, allowRedraw: true }); } But, if I write the same JSON to the page like below it works fine!? <script type="text/javascript"> //<![CDATA[ var gData = {cols: [{id: 'DATE', label: 'Date', type: 'date'}, {id: 'KEYWORD51', label: 'vw cheltenham', type: 'number'}], rows: [{c: [{v: new Date(2010, 3, 13)}, {v: 20}]}, {c: [{v: new Date(2010, 3, 14)}, {v: 19}]}, {c: [{v: new Date(2010, 3, 15)}, {v: 19}]}, {c: [{v: new Date(2010, 3, 16)}, {v: 18}]}, {c: [{v: new Date(2010, 3, 17)}, {v: 17}]}, {c: [{v: new Date(2010, 3, 18)}, {v: 17}]}, {c: [{v: new Date(2010, 3, 19)}, {v: 12}]}, {c: [{v: new Date(2010, 3, 20)}, {v: 13}]}, {c: [{v: new Date(2010, 3, 21)}, {v: 11}]}, {c: [{v: new Date(2010, 3, 22)}, {v: 10}]}, {c: [{v: new Date(2010, 3, 23)}, {v: 10}]}, {c: [{v: new Date(2010, 3, 24)}, {v: 8}]}, {c: [{v: new Date(2010, 3, 25)}, {v: 6}]}, {c: [{v: new Date(2010, 3, 26)}, {v: 6}]}, {c: [{v: new Date(2010, 3, 27)}, {v: 5}]}, {c: [{v: new Date(2010, 3, 28)}, {v: 4}]}, {c: [{v: new Date(2010, 3, 29)}, {v: 4}]}, {c: [{v: new Date(2010, 3, 30)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 1)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 2)}, {v: 1}]}, {c: [{v: new Date(2010, 4, 3)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 4)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 5)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 6)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 7)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 8)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 9)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 10)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 11)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 12)}, {v: 2}]}]}; //]]> </script> Please advise how I can get it to work correctly using a the JSON calls?

  • How to prevent jQuery FancyBox from closing immediately after submit?

    - by Dimitri
    Hi! I'm loading an inline registration form in a FancyBox from jQuery. However after submitting the form, the box immediately closes while there is some feedback that I want to show the user in the FancyBox itself. This feedback is generated on the server side and is printed in the FancyBox. How can I make the box only closing when their is no feedback anymore? I was thinking about using ajax to just refresh the FancyBox itself and not the whole page after refreshing. But I just can't figure out how this ajax $.ajax({type, cache, url, data, success}); works... Also it seems like there's no reaction from the 'submit bind' in the javascript. I hope someone can help me with this problem. I paste my code below. If any questions, plz ask.. Thx in advance! This is the javascript: <script type="text/javascript"> $(document).ready(function() { $("#various1").fancybox({ 'transitionIn' : 'none', 'transitionOut' : 'none', 'scrolling' : 'no', 'titleShow' : false, 'onClosed' : function() { $("#registration_error").hide(); } }); }); $("#registration_form").bind("submit", function() { if ($("#registration_error").val() != "Registration succeeded!") { $("#registration_error").show(); $.fancybox.resize(); return false; } $.fancybox.showActivity(); $.ajax({ type : "POST", cache : false, url : "/data/login.php", data : $(this).serializeArray(), success : function(data) { $.fancybox(data); } }); return false; }); This is the inline form that I show in the FancyBox: <div style="display: none;"> <div id="registration" style="width:227px;height:250px;overflow:auto;padding:7px;"> <?php echo "<p id=\"registration_error\">".$feed."</p>"; ?> <form id="registration_form" action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post"> <p> <label for="username">Username: </label> <input type="text" id="login_name" name="username" size="30" /> </p> <p> <label for="password">Password: </label> <input type="password" id="pass" name="pw" size="30" /> </p> <p> <label for="repeat_password">Repeat password: </label> <input type="password" id="rep_pass" name="rep_pw" size="30" /> </p> <p> <input type="submit" value="Register" name="register" id="reg" /> </p> <p> <em></em> </p> </form> </div> </div>
