  • Determine if a specific activity in an application can be launched...

    - by Justin
    Applications can have any number of launchable activities. I know how to get the list of these activities via PackageManager. Is there a way to determine which activities can be launched via startActivity? For example, the Documents To Go app has different activities that will start Word, Excel, Powerpoint, PDF, etc... I am able to launch all o these just fine. However, it also contains some activities that I am not able to launch with startActivity... If I attempt to do this I get a SecurityException. I want to be able to determine which activities I can safely launch and which I cannot so I only present the user with a list of activities that I can safely launch from within my application... Is this possible?

  • Saving elements to database with $.ajax()

    - by Justin Meltzer
    I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?: $.ajax({ type: "POST", data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'} }); Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.

    - by Alexander Gladysh
    In my bash script I have an external (received from user) string, which I should use in sed pattern. REPLACE="<funny characters here>" sed "s/KEYWORD/$REPLACE/g" How can I escape the $REPLACE string so it would be safely accepted by sed as a literal replacement? NOTE: The KEYWORD is a dumb substring with no matches etc. It is not supplied by user.

  • In iPhone OS, what UTI represents a plain ol' text file?

    - by Justin Searls
    I'm attempting to make use of the UIDocumentInteractionController mechanism in iPhone OS 3.2, but I'm struggling to figure out exactly how to construct a UTI that it likes. I've gotten as far as attempting to set "public.plain-text", but it's hard to test whether this is the correct UTI for a plain text document, since I can't tell whether the issue is that my iPad doesn't have any apps that support plain text import. (I figured Pages would, but I suppose perhaps not, since it will attempt and fail to load any files with the extension .pages, regardless of UTI). Any seasoned OS X developers that can help on this?

  • Feature activate via UI but does not show in the Libraries and Lists

    - by Justin Cullen
    I am really hating SharePoint as there are hardly any good/concrete documentation. I developed custom List "MainCatalog" with few columns (not site columns). Create features and elements with MOSS feature builder at Site collection level so scope="site" installed via stsadm activated via UI "went to site collection website", Site Setting Site collection Feature (and saw my custom list "MainCatalog") and was able to activate. then went to "mySiteCollection Site Settings Site Libraries and Lists " My list is showing But it shows in the "mySiteCollection Create Custom Lists "MainCatalog" I guess it's showing there as a template... But my intention is to deploy this list from development to test environment. EXTREMELY STRESSED. I AM ON THIS FOR LAST 8 DAYS.....

  • Web UI for showing like/dislike community comments side-by-side

    - by Justin Grant
    We want to add a comments/reviews feature to our website's plugin gallery, so users can not only vote up or down a particular plugin, but also leave an optional short comment about what they liked or didn't like about it. I'm looking for inspiration, ideally a good implementation elsewhere on the web which isn't annoying to end users, isn't impossibly complex to develop, and which enables users to see both good and bad comments side-by-side, like this: Like: 57 votes Dislike: 8 votes --------------------------------- -------------------------------- "great plugin, saved me hours..." "hard to install" "works well on MacOS and Ubuntu" "Broken on Windows Vista with UAC enabled" "integrates well with version 3.2" More... More... Anyone know a site which does something like this?

  • How do I display a view as if it's the front page via a module?

    - by Justin
    I have a simple view that feeds a home page. I have a custom module that registers some specific URLs in hook_menu that I pass into my module so I can pass them as arguments into the view. I can get the module to display the view all right, but it doesn't use the teaser/is_front view that outputs when I access the home page. I looked through the APIs but I can't seem to figure out how I can output the view via my module as if it's the front page, meaning $is_front is true and the teasers would appear. The reason I'm not passing in the arguments via the URL bar into the view itself is: My argument list is known and finite The argument order is mixed, meaning I will sometimes have /argument1, /argument1/argument2 or just /argument2. I only want to capture the first level URL as an argument for specific, known strings (e.g. I don't want to pass /admin into my view but I do want to pass in /los-angeles, which I register in the menu system via hook_menu in my module) Here are some examples to make this more clear: /admin - loads the admin page /user - loads the login page /boston - passes into the first argument of the view; shows in front/teaser mode / - shows view with no arguments /bread - passes into argument 2 of the view; shows in front/teaser mode /boston/bread - Passes into argument 1 and 2 of the view; shows in front/teaser mode Maybe I'm going about this the wrong way? Or perhaps there is a way to have a module load a view and somehow set front/teaser mode? Details: Drupal 6, PHP 5, MySQL 5, Views, CCK

  • alternative to strdup

    I am using strdup here to copy the value of the parameter name into nm in the constructor... is there an alternative of achieving the same result without using strdup and without using the C++ STL library and using the keyword new instead? Book::Book(const char *name, int thickness, int weight):nm(NULL), thck(thickness), wght(weight){ if(name) nm = strdup(name); } class Book { private: char* nm; .......... ............ .......... ........... };

  • Nerd Dinner tutorial question (can't pull data off Model)

    - by Alexander
    I am just following the tutorial about NerdDinner and was stuck because when I am implementing the "Index" View Template I got no data from it. It seems that when I loop around in the code below: <asp:Content ID="Title" ContentPlaceHolderID="TitleContent" runat="server"> Upcoming Dinners </asp:Content> <asp:Content ID="Main" ContentPlaceHolderID="MainContent" runat="server"> <h2>Upcoming Dinners</h2> <ul> <% foreach (var dinner in Model) { %> <li> <%=Html.ActionLink(dinner.Title, "Details", new { id=dinner.DinnerID }) %> on <%=Html.Encode(dinner.EventDate.ToShortDateString())%> @ <%=Html.Encode(dinner.EventDate.ToShortTimeString())%> </li> <% } %> </ul> </asp:Content> There seems to be nothing in the Model... why is this? I am pretty sure there's data in the database because the details view template worked. FYI I am following the tutorial up to this page

  • How do you keep text from wrapping in an NSTableView using NSAttributedString

    - by Justin
    I have an NSTableView that has 2 columns, one for an icon and the other for two lines of text. In the second column, the text column, I have some larger text that is for the name of an item. Then I have a new line and some smaller text that describes the state of the item. When the name becomes so large that it doesn't fit on one line it wraps (or when you shrink the window down so small that it causes the names to not fit on a single line). row1=============== | image |  some name   | | image |   idle               | row2================ | image |  some name really long name   | <- this gets wrapped pushing 'idle' out of the view | image |   idle               | =================== My question is, how could I keep the text from wrapping and just have the NSTableView display a horizontal scroll-bar once the name is too large to fit?

  • XPath: How to check multiple attributes across similar nodes

    - by Justin
    Hi, If I have some xml like: <root> <customers> <customer firstname="Joe" lastname="Bloggs" description="Member of the Bloggs family"/> <customer firstname="Joe" lastname="Soap" description="Member of the Soap family"/> <customer firstname="Fred" lastname="Bloggs" description="Member of the Bloggs family"/> <customer firstname="Jane" lastname="Bloggs" description="Is a member of the Bloggs family"/> </customers> </root> How do I get, in pure XPath - not XSLT - an xpath expression that detects rows where lastname is the same, but has a different description? So it would pull the last node above? Thanks a mill if you can help, been scratching at it for ages, and I can't find it by searching (apologies if it is) Cheers, J

  • Simple calculator app crashes when a third number key is punched.

    - by Justin
    Hi , I am a newbie to the iphone app world. So I thought I try my luck with a calculator app. Unfortunately I am running into an issue where if I press a third key in the calculator the app crashes. Sometimes I get this error EXC_BAD_ACCESS. Here is a code in my CalculatorViewController.m file. #import "CalculatorViewController.h" @implementation CalculatorViewController @synthesize screenText; - (IBAction)buttonPressed:(id)sender { NSString *title = [sender titleForState:UIControlStateNormal]; [self collect:title]; } - (void)collect:(NSString *)digitz { NSString * newText = nil; if ([digitz isEqualToString:@"+"]) { [self add:result]; big_digit = nil; } else if ([digitz isEqualToString:@"+"]) { [self sub:result]; } else if ([digitz isEqualToString:@"x"]) { [self multiply:result]; } else if ([digitz isEqualToString:@"="]) { [self equate:result]; } else { if (big_digit != nil && [big_digit isEqualToString:@"0"] == FALSE) big_digit = [big_digit stringByAppendingFormat:@"%@",digitz]; else big_digit = (NSMutableString *) digitz; result = (int) big_digit; newText = [[NSString alloc] initWithFormat: @"%@",big_digit]; } screenText.text = newText; [newText release]; } - (void)add:(int)res { NSString * newText = nil; ans = ans + res; newText = [[NSString alloc] initWithFormat: @"%@",ans]; screenText.text = newText; [newText release]; } Can anyone spot an obvious issue here. Here is the respective header file too. #import <UIKit/UIKit.h> @interface CalculatorViewController : UIViewController { UILabel *screenText; int number; int result; int ans; //NSString *big_digit; NSMutableString * big_digit ; } @property (nonatomic, retain) IBOutlet UILabel *screenText; - (IBAction)buttonPressed:(id)sender; - (void)collect:(NSString *)digitz; - (void)add:(int)num; - (void)sub:(int)num; - (void)multiply:(int)num; - (void)equate:(int)num; @end

  • Porting a PowerBuilder Application to .NET

    - by Justin Ethier
    Does anyone have any advice for migrating a PowerBuilder 10 business application to .NET? My company is considering migrating a legacy PB application to .NET (C#) and I am just wondering if anyone has any experience - good or bad - that you would like to share. The application is rather large with 10 PBL libraries, some PFC as well as custom frameworks. There are a large number of DLL calls being made as well. Finally, it uses a Microsoft SQL Server database. We have discussed porting the "core" application code to .NET and then porting more advanced functionality across as-needed.

  • Strange Sql Server 2005 behavior

    - by Justin C
    Background: I have a site built in ASP.NET with Sql Server 2005 as it's database. The site is the only site on a Windows Server 2003 box sitting in my clients server room. The client is a local school district, so for data security reasons there is no remote desktop access and no remote Sql Server connection, so if I have to service the database I have to be at the terminal. I do have FTP access to update ASP code. Problem: I was contacted yesterday about an issue with the system. When I looked in to it, it seems a bug that I had solved nearly a year ago had returned. I have a stored procedure that used to take an int as a parameter but a year ago we changed the structure of the system and updated the stored procedure to take an nvarchar(10). The stored procedure somehow changed back to taking an int instead of an nvarchar. There is an external hard drive connected to the server that copies data periodically and has the ability to restore the server in case of failure. I would have assumed that somehow an older version of the database had been restored, but data that I know was inserted 7 days and 1 day before the bug occurred is still in the database. Question: Is there anyway that the structure of a Sql Server 2005 database can revert to a previous version or be restored to a previous version without touching the actual data? No one else should have access to the server so I'm going a little insane trying to figure out how this even happened. Any ideas?

  • Is it possible to parse a URL into it's composite components?

    - by Paul Alexander
    I'd like to parse an incoming URL into it's component parts for some pre-processing before passing it into the standard MVC routing logic. For example given your standard route {controller}/{action}/{id} and the URL /user/show/10 Is there a way to have the Routing system return a dictionary containing controller, action and id keys with their corresponding values?

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by Justin Williams
    I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?
