• Drupal vs ExpressionEngine for any kind of project from simple commercial site to complex ecommerce

  - by artmania

  Hi friends... So far I've been using custom cms. lately I developed own cms with CodeIgniter, and I'm actually happy. But recently I take more design and front-end development works than deep development projects. I actually also prefer so... I have many things to do with custom cms, also some security issues, etc. I'm kind of tired of doing everyhing custom, also I want to give more time to my family... Recently I'm seriously considering to go for a ready cms, and develop custom plugins when project need sth specific. This cms should be very flexible to implement any layout. also secured (since i had some hack problems with my custom cms!) I googled so much about this. As a result 2 options: Drupal Expression Engine opensource or licensed matter is not an issue for me at all. I just consider to go for a cms that I can use for any kind of project from simple 4-5 pages company sites to complicated projects like hotels directory, ecommerce portals, etc... As I found out; EE is more userfriendly and doesnt hassle about implementing custom layout as much as Drupal does. Also EE use CodeIgniter that I'm familiar. on the other hand I found out that Drupal is 10000% flexible, we can do anything with that (requires good php knowledge), extremely powerful and has many plugins... So I can't decide!! I want to go for a cms that I will use for looooong years from now on with no problems to implement any kind of project. So which one do you recommend? Appreciate your helps! thanks a lot... Edited: http://expressionengine.com/ee2_sneak_preview/#cost this Commercial License $299.95 is for 1 setup? So I need to purchase new licence for each project? Nothing like I pay once, and use the cms for as many project as I want?

• Emgu CV - memory-leaks (memory consumption)

  - by martin pilch

  I am using EmguCV, the OpenCV wrapper for .NET. I am disposing all created objects but my app is still using more and more memory (in release configuration too). I have debugged my app using .NET Memory profiler and get this result: http://img532.imageshack.us/img532/2503/screenqv.png all objects instance count is oscilating but GChandle instance counr is increasing until my machine is unusable. Garbage collector does not release memory (i think). I am using VS 2008 professional, Win7 prof 32-bit, both up to date, and last stable version of emguCV. I can post some app code, if it will help. Thanks and sorry for my English. Martin

• Best way to escape characters before jquery post ASP.NET MVC

  - by Darcy

  Hello, I am semi-new to ASP.NET MVC. I am building an app that is used internally for my company. The scenario is this: There are two Html.Listbox's. One has all database information, and the other is initally empty. The user would add items from the database listbox to the empty listbox. Every time the user adds a command, I call a js function that calls an ActionResult "AddCommand" in my EditController. In the controller, the selected items that are added are saved to another database table. Here is the code (this gets called every time an item is added): function Add(listbox) { ... //skipping initializing code for berevity var url = "/Edit/AddCommand/" + cmd; $.post(url); } So the problem occurs when the 'cmd' is an item that has a '/', ':', '%', '?', etc (some kind of special character) So what I'm wondering is, what's the best way to escape these characters? Right now I'm checking the database's listbox item's text, and rebuilding the string, then in the Controller, I'm taking that built string and turning it back into its original state. So for example, if the item they are adding is 'Cats/Dogs', I am posting 'Cats[SLASH]Dogs' to the controller, and in the controller changing it back to 'Cats/Dogs'. Obviously this is a horrible hack, so I must be missing something. Any help would be greatly appreciated.

• REST api design to retrieve summary information

  - by Jacques René Mesrine

  I have a scenario in which I have REST API which manages a Resource which we will call Group. A Group is similar in concept to a discussion forum in Google Groups. Now I have two GET access method which I believe needs separate representations. The 1st GET access method retrieves the minimal amount of information about a Group. Given a *group_id* it should return a minimal amount of information like { group_id: "5t7yu8i9io0op", group_name: "Android Developers", is_moderated: true, number_of_users: 34, new_messages: 5, icon: "http://boo.com/pic.png" } The 2nd GET access method retrives summary information which are more statistical in nature like: { group_id: "5t7yu8i9io0op", top_ranking_users: { [ { user: "george", posts: 789, rank: 1 }, { user: "joel", posts: 560, rank: 2 } ...] }, popular_topics: { [ ... ] } } I want to separate these data access methods and I'm currently planning on this design: GET /group/:group_id/ GET /group/:group_id/stat Only the latter will return the statistical information about the group. What do you think about this ?

• Detect the language & django locale-url

  - by mamcx

  I want to deploy a website in english & spanish and detect the user browser languaje & redirect to the correct locale site. My site is www.elmalabarista.com I install django-localeurl, but I discover that the languaje is not correctly detected. This are my middlewares: MIDDLEWARE_CLASSES = ( 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'multilingual.middleware.DefaultLanguageMiddleware', 'middleware.feedburner.FeedburnerMiddleware', 'lib.threadlocals.ThreadLocalsMiddleware', 'middleware.url.UrlMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'maintenancemode.middleware.MaintenanceModeMiddleware', 'middleware.redirect.RedirectMiddleware', 'openidconsumer.middleware.OpenIDMiddleware', 'django.middleware.doc.XViewMiddleware', 'middleware.ajax_errors.AjaxMiddleware', 'pingback.middleware.PingbackMiddleware', 'localeurl.middleware.LocaleURLMiddleware', 'multilingual.flatpages.middleware.FlatpageFallbackMiddleware', 'django.middleware.common.CommonMiddleware', ) But ALWAYS the site get to US despite the fact my OS & Browser setup is spanish. LANGUAGES = ( ('en', ugettext('English')), ('es', ugettext('Spanish')), ) DEFAULT_LANGUAGE = 1 Then, I hack the middleware of locale-url and do this: def process_request(self, request): locale, path = self.split_locale_from_request(request) if request.META.has_key('HTTP_ACCEPT_LANGUAGE'): locale = utils.supported_language(request.META['HTTP_ACCEPT_LANGUAGE'].split(',')[0]) locale_path = utils.locale_path(path, locale) if locale_path != request.path_info: if request.META.get("QUERY_STRING", ""): locale_path = "%s?%s" % (locale_path, request.META['QUERY_STRING']) return HttpResponseRedirect(locale_path) request.path_info = path if not locale: locale = settings.LANGUAGE_CODE translation.activate(locale) request.LANGUAGE_CODE = translation.get_language() However, this detect fine the language but redirect the "en" urls to "es". So is impossible navigate in english. UPDATE: This is the final code (after the input from Carl Meyer) with a fix for the case of "/": def process_request(self, request): locale, path = self.split_locale_from_request(request) if (not locale) or (locale==''): if request.META.has_key('HTTP_ACCEPT_LANGUAGE'): locale = utils.supported_language(request.META['HTTP_ACCEPT_LANGUAGE'].split(',')[0]) else: locale = settings.LANGUAGE_CODE locale_path = utils.locale_path(path, locale) if locale_path != request.path_info: if request.META.get("QUERY_STRING", ""): locale_path = "%s?%s" % (locale_path, request.META['QUERY_STRING']) return HttpResponseRedirect(locale_path) request.path_info = path translation.activate(locale) request.LANGUAGE_CODE = translation.get_language()

• cpptask ordering of static libraries in gcc command line

  - by AC

  How do I force cpptask to move the static libraries to the end on arg list issued to the compiler? Here is the clause I am using <cpptasks:cc description="appname" subsystem="console" objdir="obj" outfile="dist/app_test"> <compiler refid="testsslcc" /> <linkerarg value="-L${libdir}" /> <linkerarg value="-L/usr/local/devl/lib" /> <linkerarg value="-Wl,-rpath,../lib" /> <libset libs="unittest ${libs} dsg readline ncurses gcov" /> <fileset dir="test/obj" includes="main.o" /> <fileset dir="." includes="${TCFILES}" /> <fileset dir="../lib" includes="libboost_thread.a libboost_date_time.a" /> </cpptasks:cc> when this executes, libboost_thread.a libboost_date_time.a are first files in the argument list passed the compiler, gcc -ggdb -Wl,-export-dynamic -Wshadow -Wno-format-y2k ../../lib/libboost_date_time.a ../../lib/libboost_thread.a x.cpp ... which causes compiler error. By manually moving them to the end of the argument list, the application compiles without error. gcc -ggdb -Wl,-export-dynamic -Wshadow -Wno-format-y2k x.cpp ... ../../lib/libboost_date_time.a ../../lib/libboost_thread.a And yes I have tried changing the order in the xml, and that of course didn't work. For now I am using an exec task to call gcc with the files in the correct order but this of course is a hack.

• Using HandVU with OpenCV on Mac OS X 10.6.3

  - by 23tux

  Hi, I've tried to user HandVU with OpenCV but when I tried to run "hvOpenCV config/default.conductor" I get a "Segmentation fault". Anybody know this problem? macbook:handvu-beta3 User$ hvOpenCV config/default.conductor will load conductor from file: config/default.conductor Segmentation fault I installed OpenCV through http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port on Mac OS X 10.6.3, and HandVU through http://www.movesinstitute.org/~kolsch/HandVu/doc/InstallationLinux.html#source I think it's a problem with opencv, because if I'm trying to run the peopledetect example, I get a segmentation fault too. macbook:c User$ ./peopledetect pic1.png Segmentation fault And if I try to run the facedetect sample I get an error too: macbook:c User$ ./facedetect --cascade="../../haarcascades/haarcascade_frontalface_alt.xml" Xlib: extension "RANDR" missing on display "/tmp/launch-WUMho1/org.x:0".

• SSRS 2008 - How to hide the plus icon in a group visibility toggle cell

  - by Daniel Coffman

  I have a report that shows or hides columns in a group based on a header cell. SSRS makes this pretty easy and is kind enough to place a little plus/minus icon in the toggling cell. I want to HIDE this plus/minus icon when there is only one column of data in the subgroup, because it shows that one column by default so expanding the group doesn't do anything. This really only applies to one specific group, because all the others always have more than one column of data, so a way to hide only the icon for a specific group would be fine. JavaScript won't work (I don't think) because the client ID of the plus/minus image is generated by the report and changes with each generation. see this image for more clarity: http://imgur.com/vqaQA.png

• Display Image over map layer in GeoServer

  - by iririr

  Hi I am newbie when it comes to GeoServer and trying to figure out if there is an easy way to display images on top of map layer. A background: In my application, based on a search criteria, some polygons are drawn on the map. Each polygon has a corresponding image (in TIFF format) that is stored somewhere. I want to load the image on top of the map when the user zooms in to a certain zoom level. I know this can be done using openLayers but since my images are in TIFF format, (openLayers is not able to render TIFF images as far as i know) i have to convert them to .PNG first which would be very slow considering the number of images i have. Hence I was wondering whether it would be possible to create a image layer that would retrieve an image of a certain polygon at a certain zoom level. If so, could anyone point me to an example or give me an idea on whether this is possible. I am using spring 2.5, tomcat 5, java 1.6 and geoserver 2.0 Thanks.

• Change parent class of dom object via css selectors

  Can i change parent class of some dom object on hover event via CSS selectors? For example I have such block: <span class="wBlock" > <span class="wText">Text</span> <span class="wLink"/> <\/span> and if i move mouse to span "wLink" span "wBlock" must be changed, and if i move out than it must be the same as at the begining .wLink{ padding-right:15px; background:url(/img/addlink.png) center right no-repeat; cursor:pointer; } .wText{ background-color: #1BE968; } It's something like this and if i move my cursor to plus text highlight must be changed to yellow

• NSURL URLWithString: raises exception

  - by Stephen Darlington

  In short, [NSURL URLWithString:] appears to be raising an exception. According to the documentation "If the string was malformed, returns nil." There is no mention of an exception being raised under any circumstance. In addition to this, I am both encoding the URL and checking for nil before converting the string to a URL. Can anyone offer any advice as to which exception it could be or what other error checking I should be doing before converting the URL? In case you're interested in the details, the calling code looks like this: NSString* tmpText = [newUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; if (tmpText == nil) { // error handling } else { NSURL* tmpURL = [NSURL URLWithString:tmpText]; And this is a section from the crash report download from iTunes Connect: 8 libobjc.A.dylib 0x300c1f84 objc_exception_throw 9 CoreFoundation 0x3029a598 +[NSException raise:format:arguments:] 10 CoreFoundation 0x3029a538 +[NSException raise:format:] 11 Foundation 0x30696dde -[NSURL initWithString:relativeToURL:] 12 Foundation 0x30696cd8 +[NSURL URLWithString:relativeToURL:] 13 Foundation 0x30696cae +[NSURL URLWithString:] 14 Yummy 0x000146ca -[DeliciousPostCell setUrl:] + 46 It seems that the URL was in a "bad" format somehow but that should really be returning a nil not an exception. I have never seen the exception being raised myself so I can't use XCode to trap the code and see what's happening. And the user(s) that experienced the problem never contacted me directly so I can't ask for more details. Any suggestions greatly appreciated. Update (14/7/2009): Seems like such a hack, but I added an exception block around the suspect line. I also raised a Radar bug report (#7031551) suggesting that the code should match the documentation.

• iPhone instantiating a UITabBarItem programmatically

  - by William Jockusch

  Try as I might, I cannot get this to work. Here is my latest attempt. Can someone clue me in as to why this does not work? In a method which is called by my view controller's init method: UIImage *image = [UIImage imageNamed: @"window22.png"]; UITabBarItem *item = [[UITabBarItem alloc] initWithTitle: @"Some Title" image: image tag: 0]; self.tabBarItem = item; All it does is put a big square where the image should be. The title in the tab bar remains the same as the view controller's title. Everything is being instantiated programmatically here, including the tab bar controller.

• MVVM Madness: Commands

  - by JP

  I like MVVM. I don't love it, but like it. Most of it makes sense. But, I keep reading articles that encourage you to write a lot of code so that you can write XAML and don't have to write any code in the code-behind. Let me give you an example. Recently I wanted to hookup a command in my ViewModel to a ListView MouseDoubleClickEvent. I wasn't quite sure how to do this. Fortunately, Google has answers for everything. I found the following articles: http://blog.functionalfun.net/2008/09/hooking-up-commands-to-events-in-wpf.html http://joyfulwpf.blogspot.com/2009/05/mvvm-invoking-command-on-attached-event.html http://sachabarber.net/?p=514 http://geekswithblogs.net/HouseOfBilz/archive/2009/08/27/adventures-in-mvvm-ndash-binding-commands-to-any-event.aspx http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/ While the solutions were helpful in my understanding of commands, there were problems. Some of the aforementioned solutions rendered the WPF designer unusable because of a common hack of appending "Internal" after a dependency property; the WPF designer can't find it, but the CLR can. Some of the solutions didn't allow multiple commands to the same control. Some of the solutions didn't allow parameters. After experimenting for a few hours I just decided to do this: private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e) { ListView lv = sender as ListView; MyViewModel vm = this.DataContext as MyViewModel; vm.DoSomethingCommand.Execute(lv.SelectedItem); } So, MVVM purists, please tell me what's wrong with this? I can still Unit test my command. This seems very practical, but seems to violate the guideline of "ZOMG... you have code in your code-behind!!!!" Please share your thoughts. Thanks in advance.

• How to use webbrowser control DocumentCompleted event in C# ?

  - by Margus

  Before starting writing this question, i was trying to solve following // 1. navigate to page // 2. wait until page is downloaded // 3. read and write some data from/to iframe // 4. submit (post) form The problem was, that if a iframe exists on a web page, DocumentCompleted event would get fired more then once (after each document has been completed). It was highly likely that program would have tried to read data from DOM that was not completed and naturally - fail. But suddenly while writing this question 'What if' monster inspired me, and i fix'ed the problem, that i was trying to solve. As i failed Google'ing this, i thought it would be nice to post it here. private int iframe_counter = 1; // needs to be 1, to pass DCF test public bool isLazyMan = default(bool); /// <summary> /// LOCK to stop inspecting DOM before DCF /// </summary> public void waitPolice() { while (isLazyMan) Application.DoEvents(); } private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) { if(!e.TargetFrameName.Equals("")) iframe_counter --; isLazyMan = true; } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { if (!((WebBrowser)sender).Document.Url.Equals(e.Url)) iframe_counter++; if (((WebBrowser)sender).Document.Window.Frames.Count <= iframe_counter) {//DCF test DocumentCompletedFully((WebBrowser)sender,e); isLazyMan = false; } } private void DocumentCompletedFully(WebBrowser sender, WebBrowserDocumentCompletedEventArgs e){ //code here } For now at least, my 5m hack seems to be working fine. Maybe i am really failing at querying google or MSDN, but i can not find: "How to use webbrowser control DocumentCompleted event in C# ?"

• Google Charts Through CURL

  - by swt83

  I have a PHP class that helps me generate URLs for custom charts using Google Chart service. These URLs work fine when I load them in my browser, but I'm trying to pull them using CURL so I can access the charts on secure https websites. Whenever I try and pull a chart via CURL, I get an Error 400 Bad Request. Any idea on how to get around this?

• Embedding icon in .exe with py2exe, visible in Vista?

  - by WindPower

  Hello, I've been trying to embed an icon (.ico) into my "compyled" .exe with py2exe. Py2Exe does have a way to embed an icon: windows=[{ 'script':'MyScript.py', 'icon_resources':[(1,'MyIcon.ico')] }] And that's what I am using. The icon shows up fine on Windows XP or lower, but doesn't show at all on Vista. I suppose this is because of the new Vista icon format, which can be in PNG format, up to 256x256 pixels. So, how can I get py2exe to embed them into my executable, without breaking the icons on Windows XP? I'm cool with doing it with an external utility rather than py2exe - I've tried this command-line utility to embed it, but it always corrupts my exe and truncates its size for some reason.

• Objective-C runtime reflection (objc_msgSend): does it violate the iPhone Developer License Agreemen

  - by GamingHorror

  Does code like this (potentially) violate the iPhone Developer License Agreement? Class clazz = NSClassFromString(@"WNEntity"); id entity = [clazz entityWithImage:@"Icon.png"]; SEL setPositionSelector = NSSelectorFromString(@"setPosition:"); objc_msgSend(entity, setPositionSelector, CGPointMake(200, 100)); I'm working on code that dynamically allocates classes from XML and calls methods on them via objc_msgSend. It's just very convenient constructing my objects that way but it worries me because i have no idea whether this is ok or violates the License by dynamically executing code or maybe even calling private (?) API functions. They wouldn't be documented if they were private, right? Can someone shed some light on this? Have you had an App approved or rejected using code similar to the above? I'm pretty sure that this is ok but i wan't to hear it from someone else! :)

• OutOfMemoryException with Image.Clone - Only on Windows 2003

  - by Jeff Rapp

  So here's my issue. I have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this: Dim bte() As Byte = System.Convert.FromBase64String(imgStr) Dim ms As New IO.MemoryStream(bte) Dim bmp As New System.Drawing.Bitmap(ms) Dim monoImage As Drawing.Bitmap = New Drawing.Bitmap(1200, 1800, Drawing.Imaging.PixelFormat.Format1bppIndexed) Dim rect As New Drawing.Rectangle(0, 0, 1200, 1800) monoImage = bmp.Clone(rect, Drawing.Imaging.PixelFormat.Format1bppIndexed) And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line. Any ideas as to what's happening, or perhaps a better solution to converting the image to B&W?

• how many fps can iPhone's UIGetScreenImage() actually do?

  - by M Katz

  Now that Apple is officially allowing UIGetScreenImage() to be used in iPhone apps, I've seen a number of blogs saying that this "opens the floodgates" for video capture on iPhones, including older models. But I've also seen blogs that say the fastest frame rate they can get with UIGetScreenImage() is like 6 FPS. Can anyone share specific frame-rate results you've gotten with UIGetScreenImage() (or other approved APIs)? Does restricting the area of the screen captured improve frame rate significantly? Also, for the wishful thinking segment of today's program, does anyone have pointers to code/library that uses UIGetScreenImage() to capture video? For instance, I'd like an API something like Capture( int fps, Rect bounds, int durationMs ) that would turn on the camera and for the given duration record a sequence of .png files at the given frame rate, copying from the given screen rect.

• Programmatically creating a toolbar in WPF

• How do I change the frame position for a custom MKAnnotationView?

  - by andrei

  I am trying to make a custom annotation view by subclassing MKAnnotationView and overriding the drawRect method. I want the view to be drawn offset from the annotation's position, somewhat like MKPinAnnotationView does it, so that the point of the pin is at the specified coordinates, rather than the middle of the pin. So I set the frame position and size as shown below. However, it doesn't look like I can affect the position of the frame at all, only the size. The image ends up being drawn centered over the annotation position. Any tips on how to achieve what I want? MyAnnotationView.h: @interface MyAnnotationView : MKAnnotationView { } MyAnnotationView.m: - (id)initWithAnnotation:(id <MKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier]) { self.canShowCallout = YES; self.backgroundColor = [UIColor clearColor]; // Position the frame so that the bottom of it touches the annotation position self.frame = CGRectMake(0, -16, 32, 32); } return self; } - (void)drawRect:(CGRect)rect { [[UIImage imageNamed:@"blue-dot.png"] drawInRect:rect]; }
