  • Getting started with Android code samples - permissions error

    - by StevenX
    New to android. Running Eclipse on Ubuntu 9.10 with Android SDK plugin installed and working. Trying to get some code samples from http://developer.android.com/resources/samples/get.html , and following its procedure to load said samples in Eclipse yields: Parent of resource: /home/user/android-sdk/platforms/android-4/samples/Notepad/.project is marked as read-only. chmod is not recursive, so I entered ~/android-sdk/platforms and "chmod 777 *" ie. all folders in /platforms. Still doesnt work. Appears to be be a bug in Eclipse that wants to create the project in the SDK folder rather than under ~/workspace.

  • How to launch a Windows process as 64-bit from 32-bit code?

    - by Jonas
    To pop up the UAC dialog in Vista when writing to the HKLM registry hive, we opt to not use the Win32 Registry API, as when Vista permissions are lacking, we'd need to relaunch our entire application with administrator rights. Instead, we do this trick: ShellExecute(hWnd, "runas" /* display UAC prompt on Vista */, windir + "\\Reg", "add HKLM\\Software\\Company\\KeyName /v valueName /t REG_MULTI_TZ /d ValueData", NULL, SW_HIDE); This solution works fine, besides that our application is a 32-bit one, and it runs the REG.EXE command as it would be a 32-bit app using the WOW compatibility layer! :( If REG.EXE is ran from the command line, it's properly ran in 64-bit mode. This matters, because if it's ran as a 32-bit app, the registry keys will end up in the wrong place due to registry reflection. So is there any way to launch a 64-bit app programmatically from a 32-bit app and not have it run using the WOW64 subsystem like its parent 32-bit process (i.e. a "*" suffix in the Task Manager)?

  • Predicates and Lists

    - by George
    Hello guys, I have a generic list. Some elements of this list belong to a parent element. I retrieved all these elements from a database and i want to recursively build a tree with them. So, here's what i'm thinking: Here is my predicate: public static bool FindChildren(Int32 parentId,CategoryMapping catMapping) { if (catMapping.parentId == parentId) { return true; } else { return false; } } root = list[0]; root.childrenElements = root.FindAll(FindChildren(root.id,???) I can't figure out how this would work. How can i do this kind of predicate?

  • insert data into several tables

    - by csetzkorn
    Let us say I have a table (everything is very much simplified): create table OriginalData ( bla char(10) not null ) And I would like to insert its data (set based!) into two tables which model inheritance create table Statements ( Id int IDENTITY NOT NULL, ProposalDateTime DATETIME null ) create table Items ( StatementFk INT not null, ItemName NVARCHAR(255) null, primary key (StatementFk) ) Statements is the parent table and Items is the child table. I have no problem doing this with one row which involves the use of IDENT_CURRENT but I have no idea how to do this set based (i.e. enter several rows into both tables). Thanks. Best wishes, Christian

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post. Thanks in advance for any help.

  • WebKit gets blank when clicking on the menu toolbar

    - by Miguel Ángel Ortuño
    Hi y'all. I've embebed a WebKit view into a modal dialog using Carbon and appereantly everything works fine. However there's a little problem. When I click on the menu toolbar the view gets completely blank getting visible only when I interact with it. Seems like the control stops reciving the 'paint window' event when I call MenuSelect function. All the events are managed by the parent window because of the nature of the application (videogame). Does anybody know what this behaviour is due to and how can I avoid it? Thanks for all.

  • nightmare with relative imports, how does pep 366 work?

    - by pygabriel
    I have a "canonical file structure" like that (I'm giving sensible names to ease the reading): mainpack/ __main__.py __init__.py - helpers/ __init__.py path.py - network/ __init__.py clientlib.py server.py - gui/ __init__.py mainwindow.py controllers.py In this structure, for example modules contained in each package may want to access the helpers utilities through relative imports in something like: # network/clientlib.py from ..helpers.path import create_dir The program is runned "as a script" using the __main__.py file in this way: python mainpack/ Trying to follow the PEP 366 I've put in __main__.py these lines: ___package___ = "mainpack" from .network.clientlib import helloclient But when running: $ python mainpack Traceback (most recent call last): File "/usr/lib/python2.6/runpy.py", line 122, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib/python2.6/runpy.py", line 34, in _run_code exec code in run_globals File "path/mainpack/__main__.py", line 2, in <module> from .network.clientlib import helloclient SystemError: Parent module 'mainpack' not loaded, cannot perform relative import What's wrong? What is the correct way to handle and effectively use relative imports? I've tried also to add the current directory to the PYTHONPATH, nothing changes.

  • How to highlight ListView item on touch?

    - by AndroidNoob
    I have a simple ListView and I want each of it items to be highlighted on user's touch. I thought this should happen by default but it isn't. Can you advice? ListView xml: <ListView android:id="@+id/list_view" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:divider="#206600" android:dividerHeight="2dp" android:smoothScrollbar="true" android:background="#ffffff" > </ListView> And code of my Adapter: private class MyAdapter extends ArrayAdapter<Task> { private LayoutInflater mInflater; public MyAdapter(Context context, int resource, List<Task> list) { super(context, resource, list); mInflater = LayoutInflater.from(context); } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { v = mInflater.inflate(R.layout.list_item, null); } Task task = taskList.get(position); /* Setup views from your layout using data in Object here */ return v; }

  • Modx: How to create a contact form with a dropdown of offices to cc the email to?

    - by code-zoop
    In the contact us template I want to have a dropdown with the list of offices (All offices articles are places under the same parent node, so getting the list should be fairly easy). I need a way to add the office email address (Template variable from the Office article) to the email generated by Modx's eForm. I don't want the email address to be visible in the contact us form, but a snippet fetching the article Template variable email address. I also want a link from each offices article to the contact us form with the office preselected in the dropdown. How should I implement this?

  • How to handle inputs in a C shell program during exec

    - by hits_lucky
    I am currently writing my own shell program. This simple shell can just execute commands. When executing commands like vi or calc which require input from the terminal , the command is getting executed and is waiting for the input from the user. But I am unable to give any input on the screen. How should the input be handled during the fork and exec. Here is the piece of code which is executing commands: if((pid = fork()) < 0) { perror("Fork failed"); exit(errno); } if(pid == 0) { // Child process if(execvp(arguments[0], arguments) == -1) { child_status = errno; switch(child_status) { case ENOENT: printf(" command not found \n"); break; } exit(errno); } } else { // parent process int wait_stat; if(waitpid(pid , &wait_stat, WNOHANG) == -1) { printf(" waitpid failed \n"); return; } } } ~ Thanks,

  • Safari on the iPhone & iPad gives colour feedback on touch, I want to stop this.

    - by Owen
    Clicking on an element which has a Javascript handler makes the element go have a 'grey overlay'. This is normally fine but I'm using event delegation to handle the touchdown events of many child elements. Because of the delegation the 'grey overlay' is appearing over the parent element and looks bad and confusing. I could attach event handlers to the individual elements to avoid the problem but this would be computationally very wasteful. I'd rather have some webkit css property that I can override to turn it off. I already have visual feedback in my app so the 'grey overlay' is not needed. Any ideas?

  • Implementing a recursive menu system a'la Joomla in CodeIgniter

    - by pettersolberg
    Hi I have some sites powered by Joomla, but with my current assignment I wanted to try something new and created with CodeIgniter a really basic CMS (just to suit my client's needs). Everything works fine except menus - multilevel menus like in Joomla, Drupal etc. with items and subitems... My question is: do you know of any tutorials or texts abut implementing such a structure. I've tried the recursion thinggy with while getting children's IDs move downwards from the parent while searching for the currently displayed item's ID. I've tried also the Drupalish way with having a path parameter enclosing ID's all the way from top to bottom '1/23/123/3'. But all in all it was just too chaotic - code something, try it out. If you have some idea on this topic - thanks in advice.

  • The 100% width HTML element problem

    - by Xeoncross
    When assigning some HTML elements (like a form input) 100% width - you can no longer apply any additional styles that might effect the width. Things like border or padding will cause the element to exceed 100%. This results in awkward elements that may be outside of their parent elements. Since CSS doesn't support width: 100% - 2px; The only way I know around this is to use an absolute pixel width (width: 98px) or chop the element off at 100% which is not really an option. <div style="overflow:hidden;"> <input style="width:100%; border: 1px solid #000;" /> </div> Are they're any other ways around this?

  • Can I access an iframe of the same domain in a separate window?

    - by jozecuervo
    How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

  • Perl: Fastest way to get directory (and subdirs) size on unix - using stat() at the moment

    - by ivicas
    I am using Perl stat() function to get the size of directory and it's subdirectories. I have a list of about 20 parent directories which have few thousand recursive subdirs and every subdir has few hundred records. Main computing part of script looks like this: sub getDirSize { my $dirSize = 0; my @dirContent = <*>; my $sizeOfFilesInDir = 0; foreach my $dirContent (@dirContent) { if (-f $dirContent) { my $size = (stat($dirContent))[7]; $dirSize += $size; } elsif (-d $dirContent) { $dirSize += getDirSize($dirContent); } } return $dirSize; } The script is executing for more than one hour and I want to make it faster. I was trying with the shell du command, but the output of du (transfered to bytes) is not accurate. And it is also quite time consuming. I am working on HP-UNIX 11i v1.

  • Unique constraint with nullable column

    - by Álvaro G. Vicario
    I have a table that holds nested categories. I want to avoid duplicate names on same-level items (i.e., categories with same parent). I've come with this: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci Unluckily, category_name_UNIQUE does not enforce my rule for root level categories (those where parent_id is NULL). Is there a reasonable workaround?

Anyone an idea?

  • Why does PHP 5.2 disallow abstract static class methods?

    - by Artem Russakovskii
    After enabling strict warnings in PHP 5.2, I saw a load of strict standards warnings from a project that was originally written without strict warnings: Strict Standards: Static function Program::getSelectSQL() should not be abstract in Program.class.inc The function in question belongs to an abstract parent class Program and is declared abstract static because it should be implemented in its child classes, such as TVProgram. I did find references to this change here: Dropped abstract static class functions. Due to an oversight, PHP 5.0.x and 5.1.x allowed abstract static functions in classes. As of PHP 5.2.x, only interfaces can have them. My question is: can someone explain in a clear way why there shouldn't be an abstract static function in PHP?

    hi, in my application ( kind of wiki clone ) - an article is frequently changing. and i need to track all changes that are done on that article. { text only. } one crude way i have done it, is to add a datetime property and create a new entity everytime something change. which is too much database wasting. { and also un-necessary index waste too. } and also need to re-create parent-child and entity relationships. i also have log which can show changes -- but i want some thing easier , so that jumping from one version to another version could be easier. ideas ? thanks.

  • What are the advantages of a rebase over a merge in git?

    - by eSKay
    In this article, the author explains rebasing with this diagram: Rebase: If you have not yet published your branch, or have clearly communicated that others should not base their work on it, you have an alternative. You can rebase your branch, where instead of merging, your commit is replaced by another commit with a different parent, and your branch is moved there. while a normal merge would have looked like this: So, if you rebase, you are just losing a history state (which would be garbage collected sometime in the future). So, why would someone want to do a rebase at all? What am I missing here?

  • How do I set properties related to the calling method's scope?

    - by Thiado de Arruda
    I'm not looking for a way to associate values with a thread using the 'SetData' method. I need to store some kind of data that will only exist during the scope of a calling method, could be the immediate parent or any other call that is made down on the stack. For example: void SomeMethod() { string someInfo = "someInfo"; SomeOtherMethod(); object data = GetDataOnCurrentScope("someKey"); } void SomeOtherMethod() { SetDataOnParentScope("someKey", somevalue); } In this case both the 'someInfo' local variable and the data set with the "someKey" key will disapear after 'SomeMethod' returns. Is something like this possible? This may go against the rules of a stack, but who knows if someone has an idea...
