• How to implement a "hidden" Android app?

  - by mawg

  I would like an application which is not readily apparent to casual perusal of the Android. How best to activate it and bring its screen to the fore? Can I detect a special dialing sequence, like *1234#? Or a hotkey combination? When activated, I guess I can pop up an anonymous screen which does not mention the app, but only asks for a password. If password is ok, then show the app. Any suggestions?

• Manually Adjusting UI for Rotation

  - by Driss Zouak

  In my view I have some number-pad type buttons that I want to manually adjust their X and Y when the view is rotated. I'm having trouble figuring out how to support this. I have added in my ViewDidLoad NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated ); And I defined my DeviceRotated but the breakpoint is never hit. I thought this might be because of the Autorotate, so I overrided the ShouldAutorotateToInterfaceOrientation and set that to false (true didn't work either). I figured there should be some WillRotate (but that's a void return type) or something that would allow me to indicate that I want the View to rotate, and whatever is set to auto adjust I'd like it to do that, but that I would like to be able to manually adjust any other items that I need. If I have to do everything myself, that's fine as well. Any advice would be appreciated, Driss.

• Strange findFn malfunction

  - by gd047

  I noticed a strange malfunction in using findFn function (library sos) and I can't find out the source. While it works fine on my Windows XP pc, it does not on my Vista one. library (sos) findFn("randomization test") # in both finds 72 results findFn("{randomization test}") # In XP finds 19 or about so, but in Vista whenever I use {} and more than one word inside, # I keep getting the following: found 0 matches x has zero rows; nothing to display. Warning message: In findFn("{randomization test}") : HIT not found in HTML; processing one page only. R ver = 2.10.1 and packages updated. Any ideas where the problem might be? Bonus: As it's obvious, I was looking for functions about tests for randomized experiments

• How to specify unique container styles for heterogenous hierarchies using SL3 and TreeView control

  - by rcecil

  Hello, Just look for strategies that have been successful in rendering hierarchies that represent inheritance structures using SL3/4 TreeViews. I need to render certain nodes differently than others, depending upon what kind of container they are (a choice between things, or simply a list of related things, etc.) So far, I've been very successful with the DataTemplate route: I've been able to use a technique described in Ted Glaza's post "Easy DataTemplateSelectors in Silverlight" (you may have retrieve a Google cache of this page). SO what I'm trying to discover is something on the order of a StyleSelector, not a DataTemplateSelector. I'm considering leveraging my current implementations of Glaza's pattern of selector objects to somehow detect the node type and set the ItemContainerStyle there, but it doesn't seem clear right now. Thanks for your thoughts.

• Excel 2007 - Worksheet is larger than the window

  - by Chris

  Hi This is an odd problem but frustrating none the less. I have a worksheet saved which is larger than the Excel 2007 "workarea". This means when I open the worksheet I cannot access the corners of the worksheet to reduce the size and the worksheets title bar area (with move,size,minimise etc) is hidden beneath the ribbon , even if I remove the ribbon , I still can't see the title bar. In Excel 2003 I've had a similar effect but I've always been able to hit the "alt" key to access the "Move" option. However in Excel 2007 , hitting "alt" brings up some shortcuts for the ribbon etc but I can't access the worksheet options. Has anyone else know how to access the worksheet drop down when this happens?

• UIViewController is popped from view stack and NSURLConnection crashes the application

  - by rickharrison

  I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

• Detecting regular expression in content during parse

  - by sonofdelphi

  I am writing a parser for C. I was just running it with some other language files (for fun, to see the extent C-likeness). It breaks down if the code being parsed contains regular expressions... Case 1: For example, while parsing the JavaScript code snippet, var phone="(304)434-5454" phone=phone.replace(/[\(\)-]/g, "") //Returns "3044345454" (removes "(", ")", and "-") The '(', '[' etc get matched as starters of new scopes, which may never be closed. Case 2: And, for the Perl code snippet, # Replace backslashes with two forward slashes # Any character can be used to delimit the regex $FILE_PATH =~ s@\\@//@g; The // gets matched as a comment... How can I detect a regular expression within the content text of a "C-like" program-file?

• ASP.NET MVC 2 Areas, Strange routing behavior

  - by user137348

  I've created an Area named "Admin". I've created also a controller(Pages) and a view(List) in this areas. When I run my app and enter the url "/Admin/Pages/List" I'm getting an The resource cannot be found error. When I enter /Pages/List, the Action method is hit but the view is not found,because the app is searching in wrong directories ~/Views/Pages/List.aspx ~/Views/Pages/List.ascx ~/Views/Shared/List.aspx ~/Views/Shared/List.ascx the view is in /Admin/Pages/List. My routing conf for Admin area: public class AdminAreaRegistration : AreaRegistration { public override string AreaName { get { return "Admin"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Admin_default", "Admin/{controller}/{action}/{id}", new { controller= "Pages",action = "Index", id = "" } ); } }

• C++'s char * by swig got problem in Python 3.0

  - by gpliu3

  Our C++ lib works fine with Python2.4 using Swig, returning a C++ char* back to a python str. But this solution hit problem in Python3.0, error is: Exception=(, UnicodeDecodeError('utf8', b"\xb6\x9d\xa.....",0, 1, 'unexpected code byte') Our definition is like(working fine in Python 2.4): void cGetPubModulus( void* pSslRsa, char* cMod, int* nLen ); %include "cstring.i" %cstring_output_withsize( char* cMod, int* nLen ); Suspect swig is doing a Bytes-Str conversion automatically. In python2.4 it can be implicit but in Python3.0 it's no long allowed.. Anyone got a good idea? thanks

• Detecting Available Qualities of YouTube Videos

  - by Langdon

  I'm writing a Boxee app that makes use of YouTube videos and I want to be able to display the highest quality version available. I was looking through the YouTube API, but I can't seem to find a way to detect if 720p and/or 1080p versions of the video are available. Does anyone know how to do this? I'm already using their Data API to collection information about the video, but there doesn't seem to be anything in the payload about different qualities consumable on the web: http://gdata.youtube.com/feeds/api/videos/NWHfY_lvKIQ I could just hard code fmt=22 and let it default to a lesser quality version, but then I miss out on 1080p (fmt=387).

• Get touches from UIScrollView

  - by Peter Lapisu

  Basically i want to subclass UIScrollView and hande the touches, however, the touch methods dont get called (i searched the web for a solution and i found out people pointing to override the hit test, what i did, but with no result :( ) .h @interface XScroller : UIScrollView @end .m - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView *result = nil; for (UIView *child in self.subviews) { if ([child pointInside:point withEvent:event]) { if ((result = [child hitTest:point withEvent:event]) != nil) { break; } } } return result; } - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"BEGAN"); [super touchesBegan:touches withEvent:event]; } - (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"MOVED"); [super touchesMoved:touches withEvent:event]; } - (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"ENDED"); [super touchesEnded:touches withEvent:event]; } - (void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"CANCELED"); [super touchesCancelled:touches withEvent:event]; } none of the - (void) touches* methods get called, the scrolling works ok

• How do I dynamically assign the Model for a .find in Ruby on Rails?

  - by Angela

  I am trying to create a Single Table Inheritance. However, the Controller must be able to know which class to find or create. These are based on another class. For example, ContactEvent with type = Letter needs to grab attributes from a corresponding Model called Letter. Here's what I've tried to do and hit a snag, labelled below. I need to be able to dynamically call assign a value of EventClass so that it can be Letter.find(:conditions =) or Calls.find(:conditions =) depending on which type the controller is acting on. def new @contact_event = ContactEvent.new @contact_event.type = params[:event_type] # can be letter, call, postcard, email @contact_event.event_id = params[:event_id] # that ID to the corresponding Model @contact_event.contact_id = params[:contact] @EventClass = case when @contact_event.type == 'letter' then 'Letter' when @contact_event.type == 'call' then 'Call' when @contact_event.type == 'email' then 'Email' SNAG BELOW: @event = @EventClass.find(@contact_letter.letter_id) #how do I make @EventClass actually the Class?SNAG # substitution of variables into the body of the contact_event @event.body.gsub!("{FirstName}", @contact.first_name) @event.body.gsub!("{Company}", @contact.company_name) @evebt.body.gsub!("{Colleagues}", @colleagues.to_sentence) @contact_event.body = @event.body @contact_event.status = "sent" end

• Parsing HTML "Visually"

  - by Midhat

  OKay I am at loss how to name this question. I have some HTML files, probably written by lord Lucifier himself, that I need to parse. It consists of many segments like this, among other html tags <p>HeadingNumber</p> <p style="text-indent:number;margin-top:neg_num ">Heading Text</p> <p>Body</p> Notice that the heading number and text are in seperate p tags, aligned in a horizontal line by css. the css may be whatever Lucifier fancies, a mixture of indents, paddings, margins and positions. However that line is a single object in my business model and should be kept as such. So How do I detect whether two p elements are visually in a single line and process them accordingly. I believe the HTML files are well formed if it helps.

• Erlang message loops

  - by Roger Alsing

  How does message loops in erlang work, are they sync when it comes to processing messages? As far as I understand, the loop will start by "receive"ing a message and then perform something and hit another iteration of the loop. So that has to be sync? right? If multiple clients send messages to the same message loop, then all those messages are queued and performed one after another, or? To process multiple messages in parallell, you would have to spawn multiple message loops in different processes, right? Or did I misunderstand all of it?

• Detecting a message box opened in another application

  - by richie

  I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation. Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the message box is closed. As the service will be running on a server there will be no user to close the message box. The service launches the legacy application in a System.Diagnostics.Process. My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox. I've tried to be brief so if you need more information please let me know. Thanks in advance Richie

• Android: automatically choose debug/release Maps api key?

  - by tomash

  Is it possible to automatically detect, which certificate was used for signing APK? I'd like to have both debug and release Maps certificates in application and pass valid one to MapView constructor. With such setup I will not make mistake while releasing application - I'm using debug certificate on emulator and my device, then sign with release one before sending app to Market. I was thinking about detecting my particular device or whether debugger is connected but it is not perfect. Maybe some file marking need for debug certificate? Is there any better way?

• split double in c wihout any libary

  - by DoomStone

  Hello I have a question for a c programmer out there, we have a tast at school to create a soft real time system in an operation system made by our teacher. Well that is all fine and dandy, we have chosen to create a system that calcuate how many unites of medicine a diabetic need based on his or hers blood sugar. It does not need to be correct just that we have the idea of a real time system :D But we have hit a little snag our formula for calculating the units of medicine is [blood sugar] * 1.2 But the only way we can send messages between processes is via a structure that contains 8 longs, but here is where my knowledge of c ends, we need for some way to split this double into 2 longs, example: the whole number in long 0 and the decimals in long 1 and then assemble it on the other side. But I have no idea who to do this, and therefore need a little help. We have tried but we do not have access to c standard libraries

• IE7 is messing up the z-index property with my subnav (although I've already fixed that!)

  - by JAG2007

  OK, so I had this issue with my jQuery subnav in IE7 where it was scrolling down behind the main content after the header. Did a fair bit of research and found a great fix involving simply applying a z-index value to the header, and one to the main content. All was well. Or so I thought. Turns out IE7 is still messing up the subnav z-index within the header itself. The subnav still drops down behind the tagline, which is also part of the header. Particularly when you hit the subnav on the "Help Now" tab. (again, IE7 only) http://betawww.helpcurenow.org I've applied z-index values to both the subnav and the tagline, but that did not resolve the issue as did adding z-index values for the header and maincontent divs. Any tips? Did I specify my z-index improperly with the subnav? (should I have applied to the parent element?)

• Livevalidation: only validate when default value is changed

  - by usr122212

  Hello there! I am validating my html form with livevalidation and everything works great except for one feature. I have a input field with a default value age, I only want the livevalidation to validate when it says something other than "age". so maybe the user will type in 20 then the validation will fire checking its things but if left as "age" it won't check it all. But as of now, it just checks everything with a validation script and this is a problem for me as I have lots of fields in my form and some of them are optional so when I hit submit, the livevalidation checks the age field as well even if the user didnt touch it to begin with. Would this be possible with livevalidation ? Thanks for the help.

• How to know from a bash script if the user abruptly closes ssh session

  - by Figo

  I have a bash script that acts as the default shell for a user loging in trough ssh. It provides a menu with several options one of wich is sending a file using netcat. The netcat of the embedded linux I'm using lacks the -w option, so if the user closes the ssh connection without ever sending the file, the netcat command waits forever. I need to know if the user abruptly closes the connection so the script can kill the netcat command and exit gracefully. Things I've tried so far: Trapping the SIGHUP: it is not issued. The only signal issued i could find is SIGCONT, but I don't think it's reliable and portable. Playing with the -t option of the read command to detect a closed stdin: this would work if not for a silly bug in the embedded read command (only times out on the first invocation)

• c# Generic overloaded method dispatching ambiguous

  - by sebgod

  Hello, I just hit a situation where a method dispatch was ambiguous and wondered if anyone could explain on what basis the compiler (.NET 4.0.30319) chooses what overload to call interface IfaceA { } interface IfaceB<T> { void Add(IfaceA a); T Add(T t); } class ConcreteA : IfaceA { } class abstract BaseClassB<T> : IfaceB<T> { public virtual T Add(T t) { ... } public virtual void Add(IfaceA a) { ... } } class ConcreteB : BaseClassB<IfaceA> { // does not override one of the relevant methods } void code() { var concreteB = new ConcreteB(); // it will call void Add(IfaceA a) concreteB.Add(new ConcreteA()); } In any case, why does the compiler not warn me or even why does it compile? Thank you very much for any answers.

• How to skip interstitial in a django view if a user hits the back button?

  - by Jose Boveda

  I have an application with an interstitial page to hold the user while an intensive operation runs in the background (takes anywhere from 30 secs to 1 minute). Once the operation is done, the user is redirected to the results page. Once on the result page, typical user behavior is to hit the 'back' button to perform the operation on a different input set. However, the back button takes them to the interstitial, not the original form. The desired behavior is to go back to the original form, skipping the interstitial entirely. I'd like this to be default behavior if the user goes to the interstitial page from anywhere but the original form. I thought I could create this by using the @never_cache function decorator in my view for the interstitial, and logic based on request.META['HTTP_REFERER'], however the page doesn't respect these. The browser's back button still trumps this behavior. Any ideas on how to solve this issue?

• Clojure multimethod dispatching on functions and values

  - by Josh Glover

  I have a function that returns the indexes in seq s at which value v exists: (defn indexes-of [v s] (map first (filter #(= v (last %)) (zipmap (range) s)))) What I'd like to do is extend this to apply any arbitrary function for the existence test. My idea is to use a multimethod, but I'm not sure exactly how to detect a function. I want to do this: (defmulti indexes-of ???) (defmethod indexes-of ??? [v s] ;; v is a function (map first (filter v (zipmap (range) s)))) (defmethod indexes-of ??? [v s] ;; v is not a function (indexes-of #(= v %) s)) Is a multimethod the way to go here? If so, how can I accomplish what I'm trying to do?

• wordpress servlet mapping not working

  - by Andrew

  I have the latest wordpress running in tomcat 6.0.26 virtual host with Quercus Servlet php servlet. It works, except when I try to use perm links. A url such as /index.php/my-page-name doesn't seem to ever hit the php server. It gets a browser error that request resource is not available. It's like it isn't matching the servlet urlmapping. I'm using a standard method in the web.xml <servlet-mapping> <servlet-name>Quercus Servlet</servlet-name> <url-pattern>*.php</url-pattern> </servlet-mapping> I see nothing showing up either in the tomcat logs when I use that url above. Any ideas please?

• Detecting DOM event support in Firefox

  - by Andy E

  What's the best way to detect event support in Firefox. Opera, Internet Explorer and Safari/Chrome all support eventName in object, but Firefox doesn't. My test case is this: javascript:alert("onclick" in document.createElement("a")) Which alerts true when entered into the address bar on the aforementioned browsers, and alerts false for Firefox. I figured out a solution using typeof on an event like so: var a = document.createElement("a"); a.setAttribute("onclick", ""); alert(typeof(a.onclick) == "function"); Is there a better method of detecting event support in Firefox?
