• Multiple buttons on screen

  - by Rajas

  I am not a game developer. I am a java developer. However I need some information and I am hoping you can help me. I want to build an app that has 3 buttons on the touch screen - 1,2 and 3. Depending on the screen input the user has to press or release button 3 but (s)he will have to keep either 1 or 2 depressed all the time. For example: Keep 1 pressed while operating button 3 or Keep 2 pressed while operating button 3. Please let me know if this is even doable. Best Regards, \|/

• Business Layer Design in J2EE Project

  - by user63157

  Currently the project on which I am working is being developed with Spring, Hibernate and struts. The business layer consists of simple java beans with no behavior in them only properties and getter and setter methods, the services are written on them which operates on them and call DAO layer methods and all. My questions is that is it object oriented way of designing or simply the procedure way in which the data and the functions on which they operate are not together. Please provide your thoughts and inputs on how the business logic is design and implemented in j2ee application, is the domain model contains business methods or are they simply dumb objects which have only data and services written on to them.

• Which C# Book to take?

  - by Fischkopf

  I was searching for a book to learn C#, but now i'm kinda stuck. I found many people asking the same question, and many people gave answers, but there are so many books about C# that it is really hard to decide which one to take. Now i reduced my choice on two books, but I just can't decide between them. Namely, there are: Programming C# 4.0 and C# 4.0 In A Nutshell The first thing I want to know, are these good choices? I'm not completely new to programming, but I just didn't find the right language until know, but i think C# is the one I was searching for. I know all the bassic stuff from Delphi/Java/Python so I think i'm not a complete beginner in programming. Is there anyone out there that read both books and can cleary explain whats the difference between them? I haven't found many reviews and sort of, so I just don't know which one to chose. Or is there any book that is better suiting me?

• j2me sprite array

  - by danis

  I`ve tried to put the same Image into an array (array contains 22 Images) to form inventory. for(int i=0;i>22;i++){ invSprite[i] = new Sprite(ingame); invSprite[i].defineReferencePixel(0,0); } and if(inventory){ for(int i=0;i>22;i++){ if(i>=11){ invSprite[i].setRefPixelPosition(0+15*i, 27); }else{ invSprite[i].setRefPixelPosition(0+15*i, 42); } invSprite[i].paint(g); } } If the inventory is on it will show those Images but it`s not. PS if I would try invSprite[0].setRefPixelPosition(10, 27); invSprite[0].paint(g); it would throw an java/lang/NullPointerException

• What is the starting point for Ubuntu app development? [closed]

  - by Roshnal

  I'm thinking of developing software for Ubuntu and other related Linux-based distros (like Linux Mint). But currently am at a loss for where to start. Would learning Python be enough/good? And what are the other things I should know about before starting this kind of developing? And will I be able to publish my apps to a software store like Ubuntu store even if I am from outside USA/UK? If not, what are the options I have to make my apps reach the audience? As a lot of users had asked, I intend to build applications only for Linux (I'm thinking of Gnome) that will be a bit business and enterprise oriented. Currently I am an Oracle certified Java developer in J2SE and J2ME. And I know Python a bit.

• Recommended Books for OpenGL [closed]

  - by TheBlueCat

  I'm fairly new to OpenGL and I'm have been researching any books that would be beneficial, I've had suggested to me (I've finished reading the OpenGL Book online): Real Time Rendering GPU Gems 3 OpenGL Super Bible Does anyone know any other books that they've found useful in the past, even if it covers higher level algorithms. Also, can anyone suggest an IDE/Text Editor for Linux? I'm using Komodo and it's super buggy, I just booted into Windows today and tried Visual Studio and loved it, is their anything similar for Linux? Although, the books I've been reading are saying to not use IDEs, partly because of the reliance you place onto them, per se. I use Eclipse a lot for my Java programming, can I use C and OpenGL with that? Lastly, do you think it would be more beneficial staying on Windows and programming in C/OpenGL on their, I do like Linux, but I found Visual Studio to be pretty good in some aspects?

• External device/USB support in android API level 10 [migrated]

  - by chandan

  I am an android UI developer and having problem with issue with USB and external storage device support on android. What I want to have is on plug-in USB/SD card, the storage items in the devices directly show up on screen. For example the modern Operating systems have this feature that we plug in our device and it just automatically shows the contents of the device on new window. I am implementing my UI on android API level 10 and my device is IMX reference kit which has android 2.3.4 installed. I would be grateful if anyone could give specif suggestion or guideline. I already tried with external_storage.java class. but it only says that the APK is installed successfully. But no action launches on plug-in external device.

• What IDE(s) or editor(s) do companies like Google, Apple, IBM, etc. use?

  - by Pius

  Even though I have quite some experience in using various tools, I still can't make up my mind whether I prefer using IDE or a simple editor for code editing. Most IDEs I have experienced are written in Java (like Eclipse) which makes them slow and bulky. What's good about them is that it provides lots of tools. On the other hand editors are usually VERY fast. They can also be extended to become more similar to IDEs but usually I don't do that. However, there is Sublime Text 2 which has some basic code completion built-in. My question would be whether most Enterprise companies like Google, Apple, IBM and etc (except Microsoft because they have AMAZING IDE which, I assume, is used by MS developers) force their workers to use IDEs and whether using plain editor with external tools is considered being not professional? P.S. Not talking about cases like Android development where working without IDE barely possible.

• What motivated Facebook to choose PHP and Twitter to choose Rails? [closed]

  - by mallieem saleie

  Possible Duplicates: Why did Facebook, Wordpress, vBulletin use PHP/MySQL? Why did Facebook use C++ beside PHP? While Facebook chose PHP and Twitter chose Ruby on Rails, I stopped and asked myself a question! why did they chose PHP and Ruby on Rails? Why not ASP.NET or Java? Is it because of bieng open source? or what?. I just want to know the right reason so I can examine their vision and decide which technology should I use if I want to build something unique.

• RegGetValue vs RegQueryValueEx

  - by baltusaj

  I have a program coded by someone else. It has a function RegGetValue used as: uFuncReturnValue = RegOpenKeyExA( HKEY_LOCAL_MACHINE, acSubKey, NULL, KEY_READ | KEY_WRITE, &hRegistry ); if( uFuncReturnValue != ERROR_SUCCESS ) { printf("Unable to open registry with error %u\n", uFuncReturnValue); exit(EXIT_FAILURE);; } uFuncReturnValue = RegGetValueA( hRegistry, NULL, "\\DosDevices\\C:", RRF_RT_REG_BINARY, NULL, (LPVOID)&structVal, &dwSize ); This block of code works perfectly on Windows 7 but returns error when run on Windows XP (32 bit). As 32-bit xp don't have RegGetValue function so I am trying to make use of RegQueryValueEX but I am having problem in passing arguments to this function. I think it should be used some thing like: uFuncReturnValue = RegQueryValueExA ( hRegistry, "\\DosDevices\\J:", NULL, NULL, (LPBYTE) &structVal, &dwSize ); But something is wrong here because the code compiles successfully but when I execute it I get a message: The program '(128) myProgram.exe: Native' has exited with code 1 (0x1). Can someone help me here please?

• Programmatically examine DLL contents

  - by Peter Hansen

  Is it possible programmatically to discover the exported names (globals, entry points, whatever) in a Windows DLL file without implementing a parser for the binary executable file format itself? I know there are tools to do this (though no open source ones I've found), but I'm curious whether there is a Windows API to accomplish the same thing or whether such tools operate merely by examining the binary file directly. I suspect there is an API for .NET libraries: if that's the case then is there a similar one for native DLLs? Edit: http://stackoverflow.com/questions/1128150 is basically an exact duplicate. The answer there is roughly "there is no API, but you can hack it using LoadLibraryEx() and navigating a few resulting data structures". Edit: I was able to use the accepted answer at http://stackoverflow.com/questions/1128150 to create a quick DLL dumper with Python and ctypes that works.

• WPF HwndHost keyboard focus

  - by Adal

  The chart area in the screenshot is a HwndHost control which hosts a native Win32 window (with it's own registered WNDCLASS) implemented in C++/CLI and drawn with Direct2D. The HwndHost is hosted in a WPF Border control. The problem I have is that I can't set the keyboard focus to the hosted Win32 window. I want the focus to move to the hosted Win32 window when the used clicks on the chart area. I tried calling SetFocus on WM_LBUTTONDOWN, but that screws app the focus in the rest of the application. Currently, even if I click on the Win32 window, the focus remains on the tree-view on the left, and if I press the up/down cursor keys, the tree-view will get them, not the chart window. How do I make the hosted Win32 window receive keyboard input from when the user clicks on the chart area, until it clicks on another control (like the tree-view, or the toolbar)?

• vs2010: trying to debug javascript using Chrome: this is not a valid location for a breakpoint

  - by George

  Everytime I try to set a debug point in Javascript, eietehr while in Design mode or while runniong, I get the error: trying to set a breakpoint in javascript: this is not a valid location for a breakpoint When I go to VS2010's Options screen under Debugging Just In Time, I see that Managed, Native & Script are selected, I also placed the line "debugger;" in the first line of a javascript function that is called but the break is never hit. In the Web.Config (although this is probably for compiled code:): <compilation debug="true I'm reliving this problem on a new machine...Can u help? Edit: I left out a huge detail: Google Chrome is my default browser. (I am trying to debug a Chrome-only error.) Must I resort to other debug tools other than VS2010? I am thinking that it should work. Too hopeful, eh?

• C# Windows Media Player - Repeat single song in a playlist

  - by Professor Mustard

  I have a PlayList loaded into my WMP instance, and I want it to loop just one song. Everything I've Googled up so far tells me to do this: private AxWindowsMediaPlayer wmp; wmp.settings.setMode("loop", true); However, this only seems to make the entire PlayList repeat. The behavior I want is that, if I enable "repeat" when song 5 in the PlayList is playing, then song 5 will keep automatically repeat when it finishes (instead of proceeding to song 6). Most car MP3 players already work this way; is there a nice native way to do this in my C# program, or will I have to devise a "hack" solution, like intercepting the event that fires when the next song is loaded?

• Matlab and .NET Interaction

  - by adyaron

  Hi All! I'm having an issue interacting between Matlab and .NET. I've managed to call .NET methods from Matlab code and vice versa. However, if I call a .NET method that, in turn, instantiates a Matlab object, it crashes (with a type initialization exception). Think about this scenario: a .NET assembly is interacting with a Matlab dll that was deployed for .NET (not native) by Matlab's deploytool. Now, when I'm loading the above .NET dll in a Matlab program everything is ok until I run a method that utilizes the other Matlab dll. Only then everything crashes. The exact message is: Warning: Cannot initialize MATLAB Compiler-generated software component in MATLAB. MATLAB Compiler-generated software components cannot be used from within MATLAB. Please don't offer not to use Matlab-.NET-Matlab architecture, it's not an option. Thank you very much (I promise to accept the answer that solves the problem :-)), Yaron.
