• Mac OS X linker error in Qt; CoreGraphics & CGWindowListCreate

  - by Jake Petroules

  Here is my .mm file #include "windowmanagerutils.h" #ifdef Q_OS_MAC #import </System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Headers/CGWindow.h> QRect WindowManagerUtils::getWindowRect(WId windowId) { CFArrayRef windows = CGWindowListCreate(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); return QRect(); } QRect WindowManagerUtils::getClientRect(WId windowId) { return QRect(); } QString WindowManagerUtils::getWindowText(WId windowId) { return QString(); } WId WindowManagerUtils::rootWindow() { QApplication::desktop()->winId(); } WId WindowManagerUtils::windowFromPoint(const QPoint &p, WId parent, bool(*filterFunction)(WId)) { return NULL; } void WindowManagerUtils::setTopMostCarbon(const QWidget *const window, bool topMost) { if (!window) { return; } // Find a Cocoa equivalent for this Carbon function // [DllImport("/System/Library/Frameworks/Carbon.framework/Versions/Current/Carbon")] // OSStatus ret = HIViewSetZOrder(this->winId(), kHIViewZOrderAbove, NULL); } #endif The linker is telling me "_CGWindowListCreate" is undefined. What libraries must I link to? Apple's documentation is not very helpful on telling what to include or link to, like MSDN is. Also I couldn't just do #import <CGWindow.h>, I had to specify the absolute path to it... any way around that?

• How to read LARGE Sqlite file to be copied into Android emulator, or device from assets folder?

  - by Peter SHINe ???

  I guess many people already read this article: Using your own SQLite database in Android applications: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/comment-page-2/#comment-12368 However it's keep bringing IOException at while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } I’am trying to use a large DB file. It’s as big as 8MB I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above. However, When I debug, it keeps showing IOException at length=myInput.read(buffer) I suspect it’s caused by trying to read a big file. If not, I have no clue why. I tested the same code using much smaller text file, and it worked fine. Can anyone help me out on this? I’ve searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy. I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don’t think this will work either. Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly? I will really appreciate anyone’s considerate answer. Thank you. WITH MORE DETAIL: private void copyDataBase() throws IOException{ //Open your local db as the input stream InputStream myInput = myContext.getAssets().open(DB_NAME); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; //Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); //transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } //Close the streams myOutput.flush(); myOutput.close(); myInput.close(); }

• sqlite3 - stringWithUTF8String is leaking!

  - by Darko Hebrang

  I would appreciate if someone could help me solve my leaking problem. The leaks occur at: aImage, aCategory, aDescription, category and categories.

• Standardizing a Release/Tools group on a specific language

  - by grahzny

  I'm part of a six-member build and release team for an embedded software company. We also support a lot of developer tools, such as Atlassian's Fisheye, Jira, etc., Perforce, Bugzilla, AnthillPro, and a couple of homebrew tools (like my Django release notes generator). Most of the time, our team just writes little plugins for larger apps (ex: customize workflows in Anthill), long-term utility scripts (package up a release for QA), or things like Perforce triggers (don't let people check into a specific branch unless their change description includes a bug number; authenticate against Active Directory instead of Perforce's internal passwords). That's about the scale of our problems, although we sometimes tackle something slightly more sizable. My boss, who is reasonably technical, has asked us to standardize on one or two languages so we can more easily substitute for each other. He's advocating bash scripts and Perl, due to their universality and simplicity. I can see his point--we mostly do "glue", so why not use "glue" languages rather than saddle ourselves with something designed for much larger projects? Since some of the tools we work with are Java-based, we do need to use something that speaks JVM sometimes. (The path of least resistance for these projects is BeanShell and Groovy.) I feel a tremendous itch toward language advocacy, but I'm trying to avoid saying "We should use Python 'cause I like it and Perl is gross." Instead, I'm trying to come up with a good approach to defining our problem set: what problems do we solve with scripts? Would we benefit from a library of common functions by our team, or are most of our projects more isolated? What is it reasonable to expect my co-workers to learn? What languages give us the most ease of development and ease of modification? Can you folks suggest some useful ways to approach this problem, both for my own thinking process and to help me facilitate some brainstorming among my coworkers?

• Purge complete Python installation on OS X

  - by Konrad Rudolph

  I’m working on a recently-upgraded OS X Snow Leopard and MacPorts and I’m running into problems at every corner. The first problem is the sheer number of installed Python versions: altogether, there are four: 2.5, 2.6 and 3.0 in /Library/Frameworks/Python.framework 2.6 in /opt/local/Library/Frameworks/Python.framework/ (MacPorts installation) So there are at least two useless/redundant versions: 2.5 and the redundant 2.6. Additionally, the pre-installed Python is giving me severe problems because some of the pre-installed libraries (in particular, scipy, numpy and matplotlib) don’t work properly. I am sorely tempted to purge the complete /Library/Frameworks/Python.framework path, as well as the MacPorts Python installation. After that, I’ll start from a clean slate by installing a properly configured Python, e.g. that from Enthought. Am I running headlong into trouble? Or is this a sane undertaking? (In particular, I need a working Python in the next few days and if I end up with a non-working Python this would be a catastrophe of medium proportions. On the other hand, some features I need from matplotlib aren’t working now.)

• filterSecurityInterceptor and metadatasource implementation spring-security

  - by Mike

  Hi! I created a class that implements the FilterInvocationSecurityMetadataSource interface. I implemented it like this: public List<ConfigAttribute> getAttributes(Object object) { FilterInvocation fi = (FilterInvocation) object; Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); Long companyId = ((ExtenededUser) principal).getCompany().getId(); String url = fi.getRequestUrl(); // String httpMethod = fi.getRequest().getMethod(); List<ConfigAttribute> attributes = new ArrayList<ConfigAttribute>(); FilterSecurityService service = (FilterSecurityService) SpringBeanFinder.findBean("filterSecurityService"); Collection<Role> roles = service.getRoles(companyId); for (Role role : roles) { for (View view : role.getViews()) { if (view.getUrl().equalsIgnoreCase(url)) attributes.add(new SecurityConfig(role.getName() + "_" + role.getCompany().getName())); } } return attributes; } when I debug my application I see it reaches this class, it only reaches getAllConfigAttributes method, that is empty as I said, and return null. after that it prints this warning: Could not validate configuration attributes as the SecurityMetadataSource did not return any attributes from getAllConfigAttributes(). My aplicationContext- security is like this: <beans:bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy"> <filter-chain-map path-type="ant"> <filter-chain filters="sif,filterSecurityInterceptor" pattern="/**" /> </filter-chain-map> </beans:bean> <beans:bean id="filterSecurityInterceptor" class="org.springframework.security.web.access.intercept.FilterSecurityInterceptor"> <beans:property name="authenticationManager" ref="authenticationManager" /> <beans:property name="accessDecisionManager" ref="accessDecisionManager" /> <beans:property name="securityMetadataSource" ref="filterSecurityMetadataSource" /> </beans:bean> <beans:bean id="filterSecurityMetadataSource" class="com.mycompany.filter.FilterSecurityMetadataSource"> </beans:bean> what could be the problem?

• How do I supply extra info to IApplicationSettingsProvider class?

  - by joebeazelman

  Perhaps this question has been asked before in a different way, but I haven’t been able to find it. I have one or more plugin adapter assemblies in my application all having the type IPlugin, for instance. Each adapter has its own settings structures stored in a common directory. Whether they are stored in one contiguous file or in separate ones doesn’t matter. Each adapter can have one or more settings associated with it. The settings will have both a name and the Plugin it will be used for. How would I create such a configuration system using the following requirements: I want to use .NETs built in settings system and avoid writing one from scratch The host application will be responsible for locating the plugin settings and passing it to the plugin Each plugin will be responsible for reading and writing its own settings to separate concerns. The host application should call Plugin.Save(thePath) and it does its thing. All settings are user scoped So far, I realize that I would need to write my own SettingsProvider, but the provider seems to work in isolation in that there’s no way to pass it parameters such as the path of the plugin directory and the name of the settings. All of the example code I've seen has the provider getting the data from the runtime environment.

• Binding properties in code behind

  - by drasto

  I have WPF application and a window in it. Lets have something like this in my xml: <Label Name="TitleLabel" Content="Some title" \> <Label Name="BottomLabel" Content="{Binding ElementName=TitleLabel Path=Content"> Lets say I don't cannot use xml for creation of BottomLabel and TitleLabel. So I have to create the BottomLabel as a property in my "Code behind". How do I specify the same binding for Content property of Bottom label in my code behind ? Is it possible at all ? So I would have something like this: public Label TitleLabel {get; private set;} public Label BottomLabel {get; private set;} public MyClass(){ TitleLabel = new Label(); TitleLabel.Content = "Some title"; BottomLabel = new Label(); BottomLabel.Content = // ?? what should be here ? How do I specify the binding // that binds BottomLabel.COntent to TitleLabel.Content? } What can I write instead of the comment ? Thank you for ansvers.

• Authentication Problem - not recognizing 'else' - Ruby on rails...

  - by bgadoci

  I can't seem to figure out what I am doing wrong here. I have implemented the Super Simple Authentication from Ryan Bates tutorial and while the login portion is functioning correctly, I can't get an error message and redirect to happen correctly for a bad login. Ryan Bates admits in his comments he left this out but can't seem to implement his recommendation. Basically what is happening is that when someone logs in correctly it works. When a bad password is entered it does the same redirect and flashes 'successfully logged in' thought they are not. The admin links do not show (which is correct and are the links protected by the <% if admin? %) but I need it to say 'failed login' and redirect to login path. Here is my code: SessionsController class SessionsController < ApplicationController def create if session[:password] = params[:password] flash[:notice] = 'Successfully logged in' redirect_to posts_path else flash[:notice] = "whoops" redirect_to login_path end end def destroy reset_session flash[:notice] = 'Successfully logged out' redirect_to posts_path end end ApplicationController class ApplicationController < ActionController::Base helper_method :admin? protected def authorize unless admin? flash[:error] = "unauthorized request" redirect_to posts_path false end end def admin? session[:password] == "123456" end helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details # end

• Databinding to Classmember of Classmember

  - by Walter

  Hello, I need some help about WPF and Databinding. Let's say I have a ClassA with a member of ClassB. ClassB has again a member, maybe an int: ClassB { public int MemberOfB { get; set; } } ClassA { private ClassB _theB; public ClassB MemberOfA { get {return _theB;} set { _theB = value; // Need to do something here... } } } When I have a Databinding in XAML like this: <TextBox Text="{Binding Path=MemberOfA.MemberOfB}"/> Where the Datacontext of the Textbox is an object of type ClassA. As you can see, i need to do some computations in the setter of MemberOfA in ClassA. But with the databinding above, this setter is of course never called, because it binds to the member of ClassB. So, how can i get to be informed if the MemberOfA changes (when I Type something into the Textbox)? Are there any best practices? (Didn't check the code in Visual Studio, so there may be some syntax errors). Thanks, Walter

• WPF : Multiple views, one DataContext

  - by zapho

  Hi, I'm working on a WPF application which must handle multiple screens (two at this this time). One view can be opened on several screens and user actions must be reflected consistently on all screens. To achieve this, for a given type of view, a single DataContext is instantiated. Then, when a view is displayed on a screen, the unique DataContext is attached to it. So, one DataContext, several views (same type of view/xaml). So far so good. It works quite well in most cases. I do have a problem with a specific view which relies on ItemsControl. These ItemsControl are used to display UIElements dynamically build in the ViewModel/DataContext (C# code). These UIElements are mostly Path objects. Example : <ItemsControl ItemsSource="{Binding WindVectors}"> <ItemsControl.Template> <ControlTemplate TargetType="{x:Type ItemsControl}"> <Canvas IsItemsHost="True" /> </ControlTemplate> </ItemsControl.Template> </ItemsControl> Here, WindVectors is a ObservableCollection<UIElement>. When the view is opened the first time, everything is fine. The problem is that when the view is opened one another screen, all ItemsControl are removed from the first screen and displayed one the second screen. Other WPF components (TextBlock for instance) on this view react normally and are displayed on both screens. Any help would be greatly appreciated. Thanks. Fabrice

• Connecting to SFTP service via Java Runtime process

  - by ohseekay

  Under my project, I have a Java class file, inside of which I have a routine which executes the following external SFTP script file: #!/bin/sh echo "cd AV/OASIS" >> sftp echo "put $1 $2" >> sftp echo "get AV/OASIS/$2 $3$2" >> sftp echo "bye" >> sftp /usr/local/bin/sftp -b sftp id@domain cat /dev/null > sftp exit 0 The Java code which executes the script file is as below: String script = "full path of script"; Process p = Runtime.getRuntime().exec(script + " " + param1 + " " + param2 + " " + param3); However, I'm not sure why, but the log generated by the class file always shows the error "Host key verification failed. Connection closed." I'd isolated that line in the script which connected to the remote machine, and ran it on the local machine (where this class file and script file are stored), and the command executed successfully I'd manually run the command which the Java class file will execute and it also tested okay: $ script.sh param1 param2 param3 I'd tried to look up the error message on the Internet, and apparently it seems to have something to do with known_hosts. Could this be the reason, or is there something else I'm missing? Thanks so much!

• AdornedElement Properties in a Trigger

  - by Chris Nicol

  I have an Adorner in XAML that I'm using for ErrorValidation. Basically I have a grid that I want to display on two conditions (if the "AdornedElement" IsFocused or IsMouseOver). Below is a code snippet where I'm binding - successfully - to the IsFocused of the AdornedElement, but as you can tell that only solves 1/2 the conditions. Now I can't pass another binding into the converter, nor can I create a property that handles both (needs to be XAML only solution). <AdornedElementPlaceholder x:Name="errorAdorner" /> ... <Grid x:Name="ErrorDetails" Visibility="{Binding ElementName=errorAdorner, Path=AdornedElement.IsFocused, Converter={StaticResource BooleanToVisibilityConverter}}" /> ... What I want to do is use triggers to handle this, the only problem is I can't access the AdornedElement's properties on a trigger. Something like this ... <Trigger SourceName="errorAdorner" Property="AdornedElement.IsFocused" Value="True"> <Setter TargetName="ErrorDetails" Property="Visibility" Value="Visible" /> </Trigger> This would also help as part of what I want to do is trigger animations, rather than just setting the visibility. Any help would be great.

• Binding event handlers to specific elements, using bubbling (JavaScript/jQuery)

  - by Bungle

  I'm working on a project that approximates the functionality of Firebug's inspector tool. That is, when mousing over elements on the page, I'd like to highlight them (by changing their background color), and when they're clicked, I'd like to execute a function that builds a CSS selector that can be used to identify them. However, I've been running into problems related to event bubbling, and have thoroughly confused myself. Rather than walk you down that path, it might make sense just to explain what I'm trying to do and ask for some help getting started. Here are some specs: I'm only interested in elements that contain a text node (or any descendant elements with text nodes). When the mouse enters such an element, change its background color. When the mouse leaves that element, change its background color back to what it was originally. When an element is clicked, execute a function that builds a CSS selector for that element. I don't want a mouseover on an element's margin area to count as a mouseover for that element, but for the element beneath (I think that's default browser behavior anyway?). I can handle the code that highlights/unhighlights, and builds the CSS selector. What I'm primarily having trouble with is efficiently binding event handlers to the elements that I want to be highlightable/clickable, and avoiding/stopping bubbling so that mousing over a (<p>) element doesn't also execute the handler function on the <body>, for example. I think the right way to do this is to bind event handlers to the document element, then somehow use bubbling to only execute the bound function on the topmost element, but I don't have any idea what that code looks like, and that's really where I could use help. I'm using jQuery, and would like to rely on that as much as possible. Thanks in advance for any guidance!

• WPF ListView GridView DisplayMemberBinding Center alignin content

  - by Bigginn

  I'm trying to center align data in a ListView/Gridview where I use DisplayMemberBinding. This is (partially) how my gridview looks: <ListView> <ListView.View> <GridView> <GridView.Columns> <GridViewColumn DisplayMemberBinding="{Binding Path=Timi}" Width="Auto"> <GridViewColumnHeader Content="Tími" Click="GridViewColumnHeader_Click" ></GridViewColumnHeader> </GridViewColumn> </GridView.Columns> </GridView> </ListView.View> </ListView> I tried to use CellTemplate like explained on this page http://msdn.microsoft.com/en-us/library/system.windows.controls.gridviewcolumn.celltemplate.aspx but it didn't work and then later I read somewhere that one should never use cellTemplate and DisplayMemberBinding together. So the question is : How do I center the gridview data when I use DisplayMemberBinding to bind the data to the gridview? Thanks in advance.

• C & MinGW: Hello World gives me the error "programm too big to fit in memory"

  - by user1692088

  I'm new here. Here's my problem: I installed MinGW on my Windows 7 Home Premium 32-bit Netbook with Intel Atom CPU N550, 1.50GHz and 2GB RAM. Now I made a file named hello.h and tried to compile it via CMD with the following command: "gcc c:\workspace\c\helloworld\hello.h -o out.exe" It compiles with no error, but when I try to run out.exe, it gives me following error: "program too big to fit in memory" Things I have checked: I have added "C:\MinGW\bin" to the Windows PATH Variable I have googled for about one hour, but ever since I'm a newbie, I can't really figure out what the problem is. I have compiled the same code on my 64-bit machine, compiles perfectly, but cannot be run due to 64-bit <- 16-bit problematic. I'd really appreciate, if someone could figure out, what the problem is. Btw, here's my hello.h: #include <stdio.h> int main(void){ printf("Hello, World\n"); } ... That's it. Thanks for your replies. Cheers, Boris

• Xcode - duplicate Target - new Target fails to build

  - by SirRatty

  Hi all, using Xcode 3.2.5 on 10.6.6 (10J521) I have an Xcode project containing 1 Target: "MyApp". It builds and runs successfully. As well as source and resource files, the Target contains a "Copy Files" build phase which copies "Sparkle.framework" in. The framework is in the same directory as the project. I want to duplicate this Target. Steps taken: Did "Clean all Targets". Right-clicked on the "MyApp" Target within Xcode, and then chose "Duplicate". Renamed the duplicated target to "MyAppTarget2". Selected "MyAppTarget2" as the Active Target from the popup menu in the top-left. Did "Build". The problem: error: Sparkle/Sparkle.h: No such file or directory This is puzzling! Each Build step appears to have been replicated in the duplicated Target, including the "Copy Files" phase. The Sparkle.framework exists at the path indicated by [Get Info on the Copy Phase item]. If I right-click on the Sparkle.framework file within the "Copy Files" build phase of the duplicated Target, and select "Reveal in Finder", then the correct Sparkle.framework file is shown. The required file exists at Sparkle.framework/Headers/Sparkle.h If I switch back to the original "MyApp" target, it builds and runs successfully. Am I doing something obviously wrong here? Thanks.
