• Android ROM Development. What does it take?

  - by Priyank

  Hi. I have been developing android apps out of hobby and fun. I want to get more serious about android development. One particular thing that I am very keen on doing (or atleast trying my hand at) is andoroid ROM development for specific handsets. Like, maybe outdated HTC Touch. (Elf/Elfin). I am at a loss to understand, what does it take to get started in right direction and what does it entails? I would really appreciate your help if you could point me to some resources which would highlight ROM Development for Android specifically. (Fundamentals of ROM development irrespective of OS would help too). Cheers

• What exactly does "adopt a protocol" mean in the Objective-C / Cocoa documentation ?

  - by driis

  I am a C# developer getting started on Objective-C / Cocoa Touch programming. I think I might have gotten some terms wrong because I keep thinking about them "the C# way". Specifically, I have come around the term "protocol" in various documentation and tutorials. In Objective-C, what exactly is a protocol ? Can it be compared to a C# interface ? Is the following declaration the same as saying "The class is implementing the protocol UITextFieldDelegate" ? Or is UITextFieldDelegate to be compared with a generic type parameter in C# ? @interface MyViewController : UIViewController <UITextFieldDelegate> { }

• Alternatives to UIWebView for rich content?

  - by ojreadmore

  In my app, I am displaying 4 "tabs", each are local content through a UIWebView. I create HTML markup from my simple data. This is slow to load and I'm trying to speed it up. I'm using UIWebView to accomplish these: 1. hyperlinks 2. some styling - font colors 3. HTML tables Writing my own class to handle this is okay for (1.) hyperlinks - I can use a touch event to call a method. And (2.) styling - I can use UILables to do basic formatting, no biggie here. BUT what I really love about the UIWebViews is the (3.) HTML tables! I find it troublesome to line up the UILabels in a way that mimics HTML Tables, for instance, one cell's height in a row changes the height of all cells. I'm looking for another perspective or knowledge of an alternative.

• Both screens always stay on after adding second monitor

  - by J.Merrill

  I had a single 1920x1080 monitor on a Windows 7 desktop PC and, per "power management" (not screen saver), the screen would go blank after 10 minutes. I added another monitor (2560x1600 if that matters) and since then, neither screen has ever blanked. I've tried turning on the "blank" screen saver, but that didn't help either -- I can go away for hours and when I come back, both screens are on. I've seen others with similar issues apparently caused by e.g. wireless mice that seem to move infinitesimally, but I've got the same wired mouse I had before. I can't understand why neither the screen saver nor power management is doing what it should to blank the screens, when "power management" used to do it when there was only one monitor. Maybe it doesn't matter so much with current LCD display technology (no "burn in") but doesn't a monitor use more power when "power management" hasn't turned off the display? Thanks for any suggestions.

• MS Clear Screen Saver doesn't work

  - by ufoq

  I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

• How to configure Notepad++ (Scintilla) to write below EOF after EOL [on hold]

  - by Piotr Piaseczny

  Is it possible to configure scintilla to "brake" EOL/EOF while writing ? Now, if I want to begin writing in a column after EOL, I use ALT+left mouse button and start typing after click. No idea how to begin writing below EOF. Pressing Enter key many times is the only method now. Other explanation: If You open a new document, doesnt matter what kind of (php/txt etc) all You have is just one line. If You want to write in line 5 - must press Enter 5 times. Every other editor I know (IDE in Builder C++/MultiEdit) "ignore" eof and you can write anywhere in document. Because of php/html I've found notepad++ as a best editor but I'd like to "brake" limitations of (probably) scintilla

• monitor power and lock screen (Ubuntu Lucid)

  - by xsznix

  Hi, I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself). Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)? Thanks.

• How can this be done with (N)Hibernate?

  - by Vilx-

  I'm creating a windows forms application with NHibernate. It's an MDI application, so there is no limit to how many forms the user can have open at the same time (probably many). For most forms I want to have an "OK" and a "Cancel" button. Both close the form, but "OK" also saves the modified data to the DB. The forms can be pretty complex, and the modifications are likely to touch a whole graph of objects, adding some, deleting some, and changing some more. It would be good if the changes could be automatically detected and persisted as needed, without the need to manually keep track of each of them. What would be a good way to do this? Extra information: I can make whatever DB schema I want. I'm using MSSQL 2008 and currently have decided for GUID primary keys (with guid.comb generator) and a TIMESTAMP column for optimistic concurrency. I tried to simply set FlushMode of a NHibernate ISession to Never, doing all modifications as needed, and then calling Flush() if the user clicked OK. But that didn't work.

• How to hide a scrollbar? (Windows Mobile)

  - by ikky

  Hi! I have one panel "imageHolder" I have from 4 to 20 pictureboxes (each pictureBox is 256x256px so they increase the panel's size to more than the cellphone's workarea) I have set the panel's autoscroll = true, so that a V and H scrollbar is shown. Is it possible to make these scrollbars not visible? The reason i want them to be not visible: - I want to be able to use touch to move around in the panel, and thought that i can do this by just increasing/decreasing the scrollbar's position. Is there a way to do this? (I have searched, but can't seem to find anything useful. Looks like the scrollbars are a bit limited) Do you recommend me to do it some other way?

• How to keep the Alt-Tab menu on the second monitor in Ubuntu?

  - by D Connors

  I'm running the latest Ubuntu version on my laptop, and every day when I arrive at my office I turn on the laptop and plug everything on. That includes a monitor that happens to be larger than the laptop's monitor. I always do my work on the desktop monitor, so I'd like for the Alt-Tab menu to always pop-up on this one. Instead, it's configured to pop-up whichever monitor the mouse is on (which makes sense, but doesn't work for me). Anybody know a way to change that?

• Running ubuntu 10.04 without a laptop's primary display

  - by riteshmnayak

  I have an IBM thinkpad(R50e) whose display is broken. I would still like to use the laptop by connecting it to an external monitor and keyboard/mouse. This is what I did: Removed the hard disk from the broken IBM Put the hard disk in the working IBM and installed 10.04 on it. It booted fine and I installed many packages and stuff. I put the hard disk back into the broken display IBM thinking I could use it by connecting it to an external monitor that I own. Well, it turns out that while booting, the display shows up but because the display shifts from the VGA display to the primary display mid-boot, the laptop does not boot. Is there a way in which I can force the laptop to not use its primary display while booting. I looked at Randr and also grub.conf settings but nothing seemed to work. Please help!

• How to detect touchEvent across multiple objects?

  - by RobGThai

  In short: I need to find a way to implement swipe action (touchEvent) for my Calendar just like the default Android Calendar one. I am using GridView to make a calendar for my application. When I touch any date, I launch an activity to display details on that date. My problem is that now I tried to implement swipe to change month/year to display but I dont know a way to do it. I tried to use setOnTouchListener on GridView but it seems like detecting for each grid separately instead of the whole grid as one. Further problem would be that it overridden my onItemClick implementation as well.

• Is it possible to have tab completion of drop-down lists in web pages in Firefox?

  - by Nick Booker

  Does anyone know of a Firefox plugin that would enable tab-completion (or some other key sequence like Alt-L) of items in drop-down lists in web forms? e.g. ou<TAB>in<TAB>s<TAB> for 'OurCompany - Internal Support' Vimperator's hints mode makes it very ergonomic to focus the drop-down list with a key sequence like f13 but the keyboard interface to the drop-down list still sucks. I very frequently have to pick items from a very long list with very long common prefixes among the entries (e.g. 30-40 starting with OurCompany -), which renders both the built-in keyboard interface and the mouse pretty slow and unergonomic. I basically want readline support for filling webforms!

• 'hijacking' gui and mapping certain controls to certain functions. VNC. TouchOSC

  - by Nick

  I need a VNC LIKE application which rather than sharing the screen, can take control of a specific application and then share that functionality across a network to multiple clients. Obviously, VNC requires use of the mouse and therefore only one user can do something at one time, this is NOT what I am after. I am after something that can hijack the graphic user interface, map certain controls, and then display them in another piece of software (perhaps like TOUCHOSC) The software I would like to map and share is called YAMAHA STUDIO MANAGER and is used to control certain Yamaha audio hardware, and in my case a Yamaha LS9 and M7CL mixing console. Its free.

• jquery live problem

  - by Kay

  Hi, I have a website which uses jquery and lots of mouseover/mouseout effect. So far I used the .bind() method of jquery but if you have 1000 event handlers, this is slowing down your browser a lot. So, I want to move to use .live or .delegate. One part of my portal site is a chat area. User can set chat messages which will then be displayed in a simple table. There is a feature that if you move the mouse over a chat message a trash can will appear allowing you to delete the message (if it is by you or you are a moderator). The trash bin is in the same table cell as the chat message. The problem: Using .bind() it worked like a charm. This is the old code: function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; a.appendChild(img); ctrl.appendChild(a); $(ctrl) .bind('mouseover', function(event) { $('#aDeleteChatMessage' + messageID).show() }) .bind('mouseout', function(event) { $('#aDeleteChatMessage' + messageID).hide() }); return; } 'ctrl' is the reference to a table cell. Now, using .live() the trashbin also appears but it is flickering a lot and when I move the mouse over the trashbin, it is disappearing or inactive. I have the feeling that more events are thrown or something. It seems like the 'mouseout' is thrown when moving over the trashbin, but the thrashbin is inside the tablecell so mouseout should not be triggered. The new code is as follows. $(document).ready { $('.jDeleteableChatMessage').live('mouseover mouseout', function(event) { var linkID = '#aDelete' + event.target.id; if (event.type == 'mouseover') { $(linkID).show(); } else { $(linkID).hide(); } return false; }); } function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { if (!UserIsModerator && (UserLogin != sender)) return; ctrl.id = 'ChatMessage' + messageID; var deleteString = 'Diese Chatnachricht löschen'; if (UserLang == '1') deleteString = 'Delete this chat message'; var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; img.alt = deleteString; img.title = deleteString; a.appendChild(img); ctrl.appendChild(a); $(ctrl).addClass('jDeleteableChatMessage'); } I add a class to tell jQuery which chat cell have a trash bin and which don't. I also add an ID to the table cell which is later used to determine the associated trash bin. Yes, that's clumsy data passing to an event method. And, naturally, there is the document.ready function which initialises the .live() method. So, where is my mistake?

• Cheap Wifi enabled Android or other programmable device

  - by Darran

  Does anyone know of a cheap Android or programmable device that has wifi? I need it for a project for a company that needs a wifi handheld device for the shop floor. Im not too fussed about the language the device uses though Im not really interested in the iTouch as theres no intention to release the app in the app store and I don`t really want to jail break everybodys iTouch. Ideally it would be small , iTouch size for example and relatively cheap $100 or less. Nothing fancy just ability to write a simple UI and have wifi. Voice is not needed. Not too fussed about touch or qwerty keyboard either.

• Systray stretching out for no reason.

  - by MrStatic

  I just restored my Windows install back to a previous state with Macrium. For some odd reason it is now stretching out my systray up to halfway across my taskbar. Any ideas why? No it did not do this 6 months ago when I took the image or anytime after that when I was using it. This is in Windows 7x64. The blank area seems to be filled with blank icons because if I place the mouse anywhere in the blank area the systray will slide over by about 1 icon's width. The missing icon between the battery and the volume is I assume my network icon. Not sure why that is missing as well.

• Android animation doesn't work, probably some kind of screen redraw problem.

  - by BenIOs

  I have created a custom component in my program by extending a ViewGroup. This component listens to touch events and are supposed to start animations when the user has move their finger past some certain points. I'm able to start animations while the user is touching the screen. But I'm not able to start animations if the user doesn't move their finger. It's probably that the phone thinks it doesn't have to update the screen if the user isn't moving their finger. I added some logs and according to them the animation starts and ends but it doesn't draw on the screen. I have the same problems when starting an animation with a timer. I use AlphaAnimations and TranslateAnimations on ImageViews. I have tried to use invalidate() both on the component and the ImageView but it doesn't help. Anyone who has an idea how to solve this?

• Troubleshooting an iMac

  - by Matthew

  What can I do to fix my iMac? When I start it up, it just loads forever (never getting to the Desktop). The mouse will appear then disappear, then the loading bar will sometimes appear and then disappear and it just goes in circles forever. If I start up in safe mode (by holding shift), it gets to the login window. However, if I attempt to log in the login window disappears and reappears asking for my password again. What can I do to troubleshoot this?

• Installing Chrome OS on HP Pavilion

  - by Lenny K

  Trying to install Chrome OS on HP Pavillion tx1000. I changed the BIOS to boot from USB before hard drive, and created a bootable USB drive (SanDisk Cruzer 4GB). No matter how many ways I try to make the USB drive, the laptop hangs on the startup screen, and trying to open the Boot Order Options freezes on "Fixed disk 0: ...". On the other hand, without the USB plugged in, the computer continues, and displays "Initialized Mouse", and then onto the Boot Order Options. If you let it boot normally from the beginning, it starts up fine into Windows Vista. I am using Hexxeh's Chrome OS build. Here are the different methods I've tried for making the Bootable USB Drive: Hexxeh's Image Creator (for Mac) Making the USB device bootable (using these directions). I wrote the image using Win32DiskImager. Writing the image using Win32DiskImager (without making it bootable).

• Capistrano update causes C: to be placed in the current directory (cygwin)

  - by user321775

  When I run cap deploy:update in a directory on my local machine (via cygwin), "C:" magically appears in the directory. Sure enough, I can cd to it and it's my windows C: drive. Now I'm afraid to delete it, but I definitely don't want it in this directory (a rails project under /home/username/blah/blah). Here's my config/deploy.rb file. custom options set :application, "xyz.com" set :repository, "ssh://[email protected]:yyyy/home/git/xxx" set :user, "myname" set :runner, user set :use_sudo, false server "xxx.xxx.xxx.xxx:yyyy", :app, :web, :db, :primary = true deploy to set :deploy_to, "/home/myname/public_html/xyz" repository set :scm, :git set :deploy_via, :copy ssh options default_run_options[:pty] = true ssh_options[:paranoid] = false ssh_options[:port] = yyyy start passenger namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles = :app, :except = { :no_release = true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end Anyone see the problem? And does anyone know a safe way of getting rid of the C: drives that have already shown up (this has happened in a few directories)?

• In Entity framework, we can use Model first, DB first, Code first but how can we create table programmatically

  - by AukI

  In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ). What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3. To be more specific , from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do?

• Elan Smart Pad - empty settings window

  - by Quarien

  I am using my Asus UL30JT with Windows 8. I installed Elan Smart-pad driver 11.14.1.3. It basically works just fine, I have all the gestures and stuff. However, to adjust the settings I have to launch regedit.exe, because the window appears to be broken. Under Mouse - Elan Tab - Options I see this: Do you know how to fix that? Also, if you have a similar program, can you at least send me screens of what I can change? As I said, I am editing registry right now and I need some guidance what I can actually do :)

• How do I bind Different Interfaces using Google Guice?

  Do I need to create a new module with the Interface bound to a different implementation? Chef newChef = Guice.createInjector(Stage.DEVELOPMENT, new Module() { @Override public void configure(Binder binder) { binder.bind(FortuneService.class).to(FortuneServiceImpl.class); } }).getInstance(Chef.class); Chef newChef2 = Guice.createInjector(Stage.DEVELOPMENT, new Module() { @Override public void configure(Binder binder) { binder.bind(FortuneService.class).to(FortuneServiceImpl2.class); } }).getInstance(Chef.class); I cannot touch the Chef Class nor the Interfaces. I am just a client binding to Chef's FortuneService to different Interfaces at runtime.
