• WCF done broke.

  - by SteveCav

  WCF is completely fouled up on my machine. I start a new sln in VS2008. Add a project (WCF Service Lib).Build the project (builds ok). debug the project -- it gets halfway through the progress bar and bombs out with the error below (real path changed to "my mex path" so codeproject doesn't think its spam). I'm assuming it's file permissions but don't know where to start. Any ideas?: Error: Cannot obtain Metadata from my mex path If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at somewhere unhelpful Exchange Error URI: my mex path Metadata contains a reference that cannot be resolved: 'my mex path'.

• How can I find out why a website looks different when I upload it to IIS ?

  - by UXdesigner

  Good day... I've been working on a website project, that requires to be on a Microsoft IIS Web Server. It is HTML, pure HTML, with really nice CSS, web-standards, etc. I open this website using in my computer, using Firefox, IE 8.0, Safari, Google Chrome and it looks fine everywhere. But as I upload it to the Microsoft IIS server, it changes a few things. for example: the main menu, which is a navigation bar that has dropdowns, seems to change it's line-height for some reason, and it is bigger. Some <h3> or <h2> Alignment seems wrong as well... And the lines that are supposed to surround the photographs in the website (like a frame - dotted line) won't appear. But all the rest of the CSS is loading perfectly fine. I don't think it's a path problem as everything is loading fine. But this is making me look bad and it is very important to have this done as soon as possible. Can someone give me good suggestions on what to look at ? The IIS permissions seem fine. I'm not a big Microsoft fan...but I have to develop the website there. Also, I uploaded the site to my apache server and it worked wonders. I wish I could change the policies in this corporation, but I can't. Thank you so much for your kind help.

• Making two Windows using CreateWindowsEx() - C

  - by Jamie Keeling

  Hello, I have a windows form that has a simple menu and performs a simple operation, I want to be able to create another windows form with all the functionality of a menu bar, message pump etc.. as a separate thread so I can then share the results of the operation to the second window. I.E. 1) Form A opens Form B opens as a separate thread 2)Form A performs operation 3)Form A passes results via memory to Form B 4)Form B display results I'm confused as to how to go about it, the main app runs fine but i'm not sure how to add a second window if the first one already exists. I think that using CreateWindow will allow me to make another window but again i'm not sure how to access the message pump so I can respond to certain events like WM_CREATE on the second window. I hope it makes sense. Thanks! Edit: I've attempted to make a second window and although this does compile, no windows show atall on build. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { //Fields WCHAR buffer[256]; struct DiceData storage; HWND hwnd; // Act on current message switch(message) { case WM_CREATE: AddMenus(hMainWindow); hwnd = CreateWindowEx( 0, "ChildWClass", (LPCTSTR) NULL, WS_CHILD | WS_BORDER | WS_VISIBLE, 0, 0, 0, 0, hMainWindow, NULL, NULL, NULL); ShowWindow(hwnd, SW_SHOW); break; Any suggestions as to why this happens?

• Expression Tree with Property Inheritance causes an argument exception

  - by Adam Driscoll

  Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

  Hi all i'm trying to make a simple GUI with QT 4.6. i made a separete class that represents the menu bar: MenuBar::MenuBar() { aboutAct = new QAction(tr("&About QT"), this); aboutAct->setStatusTip(tr("Show the application's About box")); connect(aboutAct, SIGNAL(triggered()), this, SLOT(about())); quitAct = new QAction(tr("&Quit"),this); quitAct->setStatusTip(tr("Exit to the program")); //connect(quitAct, SIGNAL(triggered()), &QApp, SLOT(quit())); menuFile = new QMenu("File"); menuFile->addAction(quitAct); menuLinks = new QMenu("Links"); menuAbout = new QMenu("Info"); menuAbout->addAction(aboutAct); addMenu(menuFile); addMenu(menuLinks); addMenu(menuAbout); } i can't connect the signal of the quitAct with the quit slot of the main application probably because it is not visible from the MenuBar class.. //connect(quitAct, SIGNAL(triggered()), &QApp, SLOT(quit())); how can i do it?

• Why do my Sax Parser produce no results after using InputStream Read?

  - by Andy Barlow

  Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

• How to get NEW width/height of root layout in onConfigurationChanged?

  - by jboxer

  One of our views has a ScrollView as its root layout. When the device is rotated and onConfigurationChanged() is called, we'd like to be able to get the ScrollView's new width/height. Our code looks like this: @Override public void onConfigurationChanged(Configuration newConfig) { Log.d(TAG, "Width: '" + findViewById(R.id.scrollview).getWidth() + "'"); Log.d(TAG, "Height: '" + findViewById(R.id.scrollview).getHeight() + "'"); super.onConfigurationChanged(newConfig); Log.d(TAG, "Width: '" + findViewById(R.id.scrollview).getWidth() + "'"); Log.d(TAG, "Height: '" + findViewById(R.id.scrollview).getHeight() + "'"); } And the relevant section of our AndroidManifest.xml looks like this: <activity android:name=".SomeActivity" android:configChanges="keyboardHidden|orientation"> <intent-filter> <action android:name="android.intent.action.MAIN" /> </intent-filter> </activity> On our Droid, we expected to see the ScrollView's width go to 854 when switched into landscape, and to 480 when switched back to portrait (and the height do the equivalent switch, minus the menu bar). However, we're seeing the opposite. Here's our LogCat: // Switching to landscape: 03-26 11:26:16.490: DEBUG/ourtag(17245): Width: '480' // Before super 03-26 11:26:16.490: DEBUG/ourtag(17245): Height: '778' // Before super 03-26 11:26:16.529: DEBUG/ourtag(17245): Width: '480' // After super 03-26 11:26:16.536: DEBUG/ourtag(17245): Height: '778' // After super // Switching to portrait: 03-26 11:26:28.724: DEBUG/ourtag(17245): Width: '854' // Before super 03-26 11:26:28.740: DEBUG/ourtag(17245): Height: '404' // Before super 03-26 11:26:28.740: DEBUG/ourtag(17245): Width: '854' // After super 03-26 11:26:28.740: DEBUG/ourtag(17245): Height: '404' // After super Clearly, we're getting the portrait dimensions when we switch to landscape, and the landscape dimensions when we switch to portrait. Is there something we're doing wrong? We could get hacky and solve this, but I feel like there's a simple solution that we're missing.

• How do you configure an SDL Tridion CME extension for a subset of views?

  - by Chris Summers

  I have created a new editor for SDL Tridion which adds some new functionality to the ribbon bar. This is enabled by adding the following snippet to the editor.config <!-- ItemCommenting PowerTool --> <ext:extension assignid="ItemCommenting" name="Save and&lt;br/&gt;Comment" pageid="HomePage" groupid="ManageGroup" insertbefore="SaveCloseBtn"> <ext:command>PT_ItemCommenting</ext:command> <ext:title>Save and Comment</ext:title> <ext:issmallbutton>false</ext:issmallbutton> <ext:dependencies> <cfg:dependency>PowerTools.Commands</cfg:dependency> </ext:dependencies> <ext:apply> <ext:view name="*" /> </ext:apply> </ext:extension> This is applied to all views by using a wildcard value in the node. This has results in my new button being added to the ribbon of every view, including the main dashboard. Is there a way to add this to all views except for the dashboard? Or do I have to create something like this? <ext:apply> <ext:view name="PageView" /> <ext:view name="ComponentView" /> <ext:view name="SchemaView" /> </ext:apply> If this is the only way to achieve the result I need, is there a list of all the view names somewhere?

• ActiveX not working properly with default security settings

  - by Ummar

  I have written an ActiveX control in C# and have made it working using regasm command, and it works fine as long as the security level is set to low.. Then as a next step I have made a .cab installer (ICD - Internet component downloader), and have signed my .cab file and ActiveX .dll file with a test certificate. when I hit the html page from my browser the installation parts works fine with default security settings of IE, but at the end it seems that nothing is installed and a red cross is shown on place of ActiveX. Moreover I have explored the Download Program Files folder under Windows directory, in status column it is showing word "unknown". while it is "installed" for all other activeX. what may be the problem. Moreover if i use the regasm command to register the assembly it works fine, and I have signed the ActiveX but still I have to move the security bar to low in my browser setting? why it is so? then what is the purpose of signing? I have used RegisterServer=yes in my .inf file Please let me know, if some one has gone through this problem already?

• Algorithm to detect how many words typed, also multi sentence support (Java)

  - by Alex Cheng

  Hello all. Problem: I have to design an algorithm, which does the following for me: Say that I have a line (e.g.) alert tcp 192.168.1.1 (caret is currently here) The algorithm should process this line, and return a value of 4. I coded something for it, I know it's sloppy, but it works, partly. private int counter = 0; public void determineRuleActionRegion(String str, int index) { if (str.length() == 0 || str.indexOf(" ") == -1) { triggerSuggestionList(1); return; } //remove duplicate space, spaces in front and back before searching int num = str.trim().replaceAll(" +", " ").indexOf(" ", index); //Check for occurances of spaces, recursively if (num == -1) { //if there is no space //no need to check if it's 0 times it will assign to 1 triggerSuggestionList(counter + 1); counter = 0; return; //set to rule action } else { //there is a space counter++; determineRuleActionRegion(str, num + 1); } } //end of determineactionRegion() So basically I find for the space and determine the region (number of words typed). However, I want it to change upon the user pressing space bar <space character>. How may I go around with the current code? Or better yet, how would one suggest me to do it the correct way? I'm figuring out on BreakIterator for this case... To add to that, I believe my algorithm won't work for multi sentences. How should I address this problem as well. -- The source of String str is acquired from textPane.getText(0, pos + 1);, the JTextPane. Thanks in advance. Do let me know if my question is still not specific enough.

• Render action return View(); form problem

  - by Roger Rogers

  I'm new to MVC, so please bear with me. :-) I've got a strongly typed "Story" View. This View (story) can have Comments. I've created two Views (not partials) for my Comments controller "ListStoryComments" and "CreateStoryComment", which do what their names imply. These Views are included in the Story View using RenderAction, e.g.: <!-- List comments --> <h2>All Comments</h2> <% Html.RenderAction("ListStoryComments", "Comments", new { id = Model.Story.Id }); %> <!-- Create new comment --> <% Html.RenderAction("CreateStoryComment", "Comments", new { id = Model.Story.Id }); %> (I pass in the Story id in order to list related comments). All works as I hoped, except, when I post a new comment using the form, it returns the current (parent) View, but the Comments form field is still showing the last content I typed in and the ListStoryComments View isn’t updated to show the new story. Basically, the page is being loaded from cache, as if I had pressed the browser’s back button. If I press f5 it will try to repost the form. If I reload the page manually (reenter the URL in the browser's address bar), and then press f5, I will see my new content and the empty form field, which is my desired result. For completeness, my CreateStoryComment action looks like this: [HttpPost] public ActionResult CreateStoryComment([Bind(Exclude = "Id, Timestamp, ByUserId, ForUserId")]Comment commentToCreate) { try { commentToCreate.ByUserId = userGuid; commentToCreate.ForUserId = userGuid; commentToCreate.StoryId = 2; // hard-coded for testing _repository.CreateComment(commentToCreate); return View(); } catch { return View(); } }

• Symfony + JQueryUI Tabs navigation menu question

  - by Andy Poquette

  I'm trying to use the tabs purely as a navigational menu, loading my pages in the tabs, but being able to bookmark said tabs, and have the address bar correspond with the action I'm executing. So here is my simple nav partial: <div id='tabs'> <ul> <li id='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> <li id='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> </ul> </div> And the simple tabs intializer: $(document).ready(function() { $('#tabs').tabs({spinner: '' }); }); My layout just displays $sf_content. I want to display the content for the action I'm executing (currently home or test) in the tab, via ajax, and have the tab be bookmarkable. I've googled this like 4000 times and I can't find an example of what I'm trying to do. If anyone has a resource they know of, I can look it up, or if you can help, I would greatly appreciate it. Thank you in advance.

• SWFUpload Authentication

  - by durilai

  I am using SWFUpload to do file uploading in a ASP.NET MVC 1.0 website. It is working fine, but I am not able to authenticate the upload method. The HttpContext.User.Identity.Name returns an empty string. I am assuming this is because the Flash movie is making the post. I am also using the wrapper provided here: http://blog.codeville.net/2008/11/24/jquery-ajax-uploader-plugin-with-progress-bar/. The controller action below gets fired, but as mentiond above the user object is not passed. Any help is appreciated! View HTML <form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo"> <input type="file" id="userPhoto_Photo" name="userPhoto_Photo" /> </form> Javascript $(function() { $("#userPhoto").makeAsyncUploader({ upload_url: '/Media/Upload', flash_url: '<%= Url.Content("~/Content/Flash/swfUpload-2.2.0.1.swf") %>', file_size_limit: '1 MB', file_types: '*.jpg; *.png; *.gif', button_action: SWFUpload.BUTTON_ACTION.SELECT_FILE, button_width: 210, button_height: 35, button_image_url: '<%= Url.Content("~/Content/Images/UploadPhoto.png") %>', button_text: '', button_cursor: SWFUpload.CURSOR.HAND, button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT }); }); Controller Action [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload() { if (Request.Files.Count == 1) { //Upload work } return RedirectToAction("Index", "Profile"); }

• How to push this view controller ?

  - by hib

  Hello all, I am caught in a strange requirement .See the following view hierarchy and scenario . I have a tab bar application in which I have three tabs . In first tab I am showing some content with a small image title and date (uitableview in navigation controller). In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button . On tapping each button I will push each individual view controller in the main navigation controller . Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application . On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code : UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)]; myPhotoController.navigationItem.leftBarButtonItem = backButton; [backButton release]; if([self.modalViewController isViewLoaded]){ [self dismissModalViewControllerAnimated:YES]; } modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque; [self presentModalViewController:modalNavController animated:YES]; [modalNavController release]; All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not . Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion . So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller . If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help . Thanks

• Navigation Items in UITableViewController are not appearing?

• How to output JSON from within Django and call it with jQuery from a cross domain?

  - by Emre Sevinç

  For a bookmarklet project I'm trying to get JSON data using jQuery from my server (which is naturally on a different domain) running a Django powered system. According to jQuery docs: "As of jQuery 1.2, you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". jQuery automatically replaces the ? with the correct method name to call, calling your specified callback." And for example I can test it successfully in my Firebug console using the following snippet: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any& format=json&jsoncallback=?", function(data){ alert(data.title); }); It prints the returned data in an alert window, e.g. 'Recent uploads tagged cat'. However when I try the similar code with my server I don't get anything at all: $.getJSON("http://mydjango.yafz.org/randomTest?jsoncallback=?", function(data){ alert(data.title); }); There are no alert windows and the Firebug status bar says "Transferring data from mydjango.yafz.org..." and keeps on waiting. On the server side I have this: def randomTest(request): somelist = ['title', 'This is a constant result'] encoded = json.dumps(somelist) response = HttpResponse(encoded, mimetype = "application/json") return response I also tried this without any success: def randomTest(request): if request.is_ajax() == True: req = {} req ['title'] = 'This is a constant result.' response = json.dumps(req) return HttpResponse(response, mimetype = "application/json") So to cut a long story short: what is the suggested method of returning a piece of data from within a Django view and retrieve it using jQuery in a cross domain fashion? What are my mistakes above?

• Adding a custom subview (created in a xib) to a view controller's view - What am I doing wrong

  - by Fran

  I've created a view in a xib (with an activity indicator, a progress view and a label). Then I've created .h/.m files: #import <UIKit/UIKit.h> @interface MyCustomView : UIView { IBOutlet UIActivityIndicatorView *actIndicator; IBOutlet UIProgressView *progressBar; IBOutlet UILabel *statusMsg; } @end #import "MyCustomView.h" @implementation MyCustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end In IB, I set the file's owner and view identity to MyCustomView and connect the IBOutlet to the File's owner In MyViewController.m, I've: - (void)viewDidLoad { [super viewDidLoad]; UIView *subView = [[MyCustomView alloc] initWithFrame:myTableView.frame]; [subView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]]; [myTableView addSubview:subView]; [subView release]; } When I run the app, the view is added, but I can't see the label, the progress bar and the activity indicator.

• UIScrollView + UIWebView = NO scrollsToTop

  - by sniurkst

  It looks like a problem which could have simple solution, but I haven't found anything what could lead the way to it. I'm using UIWebView inside of UIScrollView and tapping on statusBar (to scroll content to top) is not working. I've made simple test application to see if it's really UIWebViews fault. And it really is. // scrolls to top on status bar tap UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); [self.view addSubview:sv]; // doesn't scroll UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); UIWebView *wv = [[UIWebView alloc] init]; wv.frame = CGRectMake(0, 0, 320, 100); [sv addSubview:wv]; [self.view addSubview:sv]; So, I think maybe there's something I could disable to make UIWebView not to mess with scrollToTop? Or some kind of workaround also would be nice. Any ideas?

• Rails 3 get raw post data and write it to tmp file

  - by Andrew

  I'm working on implementing Ajax-Upload for uploading photos in my Rails 3 app. The documentation says: For IE6-8, Opera, older versions of other browsers you get the file as you normally do with regular form-base uploads. For browsers which upload file with progress bar, you will need to get the raw post data and write it to the file. So, how can I receive the raw post data in my controller and write it to a tmp file so my controller can then process it? (In my case the controller is doing some image manipulation and saving to S3.) Some additional info: As I'm configured right now the post is passing these parameters: Parameters: {"authenticity_token"=>"...", "qqfile"=>"IMG_0064.jpg"} ... and the CREATE action looks like this: def create @attachment = Attachment.new @attachment.user = current_user @attachment.file = params[:qqfile] if @attachment.save! respond_to do |format| format.js { render :text => '{"success":true}' } end end end ... but I get this error: ActiveRecord::RecordInvalid (Validation failed: File file name must be set.): app/controllers/attachments_controller.rb:7:in `create'

• Update a tableView with a plist took from another table

  - by Pheel

  Background: I have a tab bar application, which has a tableView as the "heart" of the app. It loads data from a plist and, through a button that checks if there are any updates on the remote plist file, updates the local plist with the remote contents. Then, i have another tableView, that should display only those plist items that have a bool value set to YES. Now i want to add a button to the second table that reloads the plist took from the first table. Expected: When i update the local plist from the first table and when i press the button on the second table, the 2nd table is supposed to update and show the cells with that bool value set to YES. (Note: I set YES as default to some items on plist). What happens: The first table updates its content from remote. The second table shows the old items with the value set to YES. When i press the button to refresh data, it reads the plist fine (by logging it, it has the same contents of the first table -only those set to YES-),but it doesn't update data even if i have [self.tableView reloadData];. When i close the app and open it again, the second table is filled with the right items. :\ Code i'm using: //Reading Plist { NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"myPlist.plist"]; NSFileManager *fMgr = [NSFileManager defaultManager]; if (![fMgr fileExistsAtPath:plistPath]) { plistPath = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"]; } NSMutableArray *returnArr = [NSMutableArray arrayWithContentsOfFile:plistPath]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"isFav == YES"]; for (NSDictionary *sect in returnArr) { NSArray *arr = [sect objectForKey:@"Rows"]; [sect setValue:[arr filteredArrayUsingPredicate:predicate] forKey:@"Rows"]; } [self.tableView reloadData]; } //Refresh data button - (void) refreshTable:(id)sender { NSLog(@"plist read"); [self readPlist]; NSLog(@"refreshed plist:%@",[self readPlist]); [self.tableView reloadData]; } Does anyone know why the table is not updating?

• What is better in WPF for UI layout, using one Grid, or nested Grids.

  - by Matthijs Wessels

  I am making a UI in WPF, I have a bunch of functional areas and I use a Grid to organize it. Now the Grid that I want is not uniform, as in, some functional area will span multiple cells in the Grid. I was wondering what the best practise is in solving this. Should I create one grid and then for each functional area set it to span multiple cells, or should I split it up into multiple nested Grids. In this image, the leftmost panel (panels separated by the gray bar) is what I want. The middle panel shows one grid where the blue lines are overlapped by a functional area. The rightmost panel shows how I could do it with nested grids. You can see the green grid has one horizontal split. In the bottom cell is the yellow Grid with a vertical split. In side the left cell is the red Grid with again a horizontal split. I was just wondering what is best practise, the middle or the right panel.

• Primefaces push encoding

  - by kalaoke

  I use primefaces push to write a message in a p:notificationBar. if i push a message with specials characters (like russians char), I've got '?' in my message. How can I fix this problem ? Thanks for your help. (config : primefaces 3.4 and jsf2. All my html pages are utf8 encoding). Here is my view code : <p:notificationBar id="bar" widgetVar="pushNotifBar" position="bottom" style="z-index: 3;border: 8px outset #AB1700;width: 97%;background: none repeat scroll 0 0 #CA837D;"> <h:form prependId="false"> <p:commandButton icon="ui-icon-close" title="#{messages['gen.close']}" styleClass="ui-notificationbar-close" type="button" onclick="pushNotifBar.hide();"/> </h:form> <h:panelGrid columns="1" style="width: 100%; text-align: center;"> <h:outputText id="pushNotifSummary" value="#{growlBean.summary}" style="font-size:36px;text-align:center;"/> <h:outputText id="pushNotifDetail" value="#{growlBean.detail}" style="font-size: 20px; float: left;" /> </h:panelGrid> </p:notificationBar> <p:socket onMessage="handleMessage" channel="/notifications"/> <script type="text/javascript"> function handleMessage(data) { var substr = data.split(' %% '); $('#pushNotifSummary').html(substr[0]); $('#pushNotifDetail').html(substr[1]); pushNotifBar.show(); } </script> and my Bean code : public void send() { PushContext pushContext = PushContextFactory.getDefault().getPushContext(); String var = summary + " %% " + detail; pushContext.push("/notifications", var);

• Good mobile oriented GWT widget library alternatives

  - by Michael Donohue

  I've been developing a travel planning site - tripgrep.com - which is built on appengine, GWT and smartgwt, among other technologies. It is still early days, and the site is now working well on my development environment, which is either a windows or mac computer. However, I am frequently talking up the website to my friends when we are at a bar or other venue, so I am standing there while they try to access the site via an iPhone, Android or Blackberry - I've witnessed all three. It has been painfully obvious that the browser based frontend takes a long time to download on a mobile device. I am pretty sure this is because of the javascript download for SmartGWT. So, I would like to look at alternatives to SmartGWT. What I like about SmartGWT is that it has a reasonable look and feel out of the box - I don't need to learn any design or css and it has an office application look. This is considerably better than the GWT built-in widgets, which just get a blue border. The better look-and-feel is why I went with SmartGWT early on. However, the slow load times are killing me on these mobile demos. So now I want a fast loading widget alternative that has good look-and-feel out of the box. The features I care about are: tabs, good form layout, Google maps API integration, grid data viewing. If those are all available in a library that loads quickly on a mobile device, then that's the library I want.

• How to scroll the horizontal scrollbar in an iFrame from the parent frame?

  - by Mohammad

  Is there any cross browser way to scroll the horizontal scroll bar of an IFrame with super wide content with Javascript inside the parent frame. Also I need it to be attached to the mouse wheel event. This is what I have so far, it's a bit copy and paste at the moment and doesn't work unfortunately. //var myIframe = document.getElementById('iframeWithWideContent'); //myIframe.onload = function (myIframe) { var mouseWheelEvt = function (e){ var event = e || window.event; if (document.body.doScroll){ document.body.doScroll(event.wheelDelta>0?"left":"right"); }else if ((event.wheelDelta || event.detail) > 0){ document.body.scrollLeft -= 10; }else{ document.body.scrollLeft += 10; } return false; } if ("onmousewheel" in document.body){ document.body.onmousewheel = mouseWheelEvt; }else{ document.body.addEventListener("DOMMouseScroll", mouseWheelEvt); } //}? I probably should uncomment that code, replace document.body with myIframe though I wouldn't know what I'm doing wrong. Demo on JSBIN link fixed Any help from you JavaScript Lords would be very appreciated. Thank you!
