  • Waiting for DialogActivity to return before continuing executing of the main thread

    - by jax
    How would I force the current thread to wait until another has finished before continuing. In my program the user selects a MODE from an AlertDialog, I want to halt executing of the program before continuing as the mode holds important configuration for the gameplay. new AlertDialog.Builder(this) .setItems(R.array.game_modes, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { switch (which) { case 0: setMode(TRAINING_MODE); case 1: setMode(QUIZ_MODE); default: setMode(TRAINING_MODE); break; } //continue loading the rest of onCreate(); contineOnCreate(); } }) .create().show(); If this is impossible can anyone give a possible solution?

  • Multithreading - are the multi-core processors really doing parallel processing?

    - by so.very.tired
    Are the modern multi-core processors really doing parallel processing? Like, take for example, Intel's core i7 processors. some of them has #of Cores: 4 and #of Threads: 8 (taken from Intel's specifications pages). If I to write a program (say in Java or C) that has multiple threads of execution, will they really be processed concurrently? My instructor said that "it is not always the case with multi-core processors", but didn't gave to much details. And why do Intel have to specify both #of Cores and #of Threads? Isn't thread just a term that describe a program-related abstraction, unlike "cores" which are actual hardware? ("Every thread runs on different core").

  • Advanced Registry Monitoring

    - by RyanTimmons91
    I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

  • Make a USB Device, Control It In Java

    - by yar
    I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well1. Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is there something better suited for communicating with Java? Note: I know that Arduino has something to do with Java (not sure what), but it seems like code must be written in a subset of C. How would I get moving on this topic? 1 - No laughter, please.

  • problem with exporting a customized form from dll

    - by mavric
    I'm working on an application so i have write an dll which contain a form with some additional work and methods. so in the beginning of my program the thread launch this form (from my dll) to get some informations and then hide it and initialize some components and the application form and then show it. when the thread come the line where it define new instance of the exported form "MyForm inputform = new MyForm();" it throw an Exception called "Top-level control cannot be added to a control." so i don't know what to do ?!!. i tried to take the code of the form from the dll source code and put it in the main program and it works.... .but still i want to know what happen and what impede my application from run that form from my dll. thanks.

  • Using a database/index sequential file independently of the Unix distribution

    - by Helper Method
    What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

  • Memory allocated with malloc does not persist outside function scope?

    - by PM
    Hi, I'm a bit new to C's malloc function, but from what I know it should store the value in the heap, so you can reference it with a pointer from outside the original scope. I created a test program that is supposed to do this but I keep getting the value 0, after running the program. What am I doing wrong? int f1(int * b) { b = malloc(sizeof(int)); *b = 5; } int main() { int * a; f1(a); printf("%d\n", a); return 0; }

  • just x86 assembly question~~!!

    - by kevin
    this is my assembly program which is just a function to swap *x *y. so first argument from main is address of x which is in 8(%ebp) and second one is address of y is in 12(%ebp). the program does swap x and y. I need 7 lines for doing this. can you make it 6 lines and there is a condition you can use only %eax,%ecx, and %edx 3 registers. I think about it so much.. but.. I can't make it 6 lines...there must be a way.. isn't it? this might be not a big deal.. but if there is a way to get it in 6lines. I want to know.. if you know the way~ help me~ plz~ thank you and have a good and nice day~ movl 8(%ebp), %eax movl (%eax), %ecx movl 12(%ebp), %edx movl (%edx), %eax movl %ecx, (%edx) movl 8(%ebp), %ecx movl %eax, (%ecx)

  • Making commercial Java software

    - by roddik
    Hi. I intend to make some software to be sold over internet. I've only created open-source before, so I have really no idea of how to protect it from being cracked and distributed as warez. Bearing in mind that I know like two programms that aren't either cracked or not really useful I decided that the only more or less reliable way may look like this: Connect to a server and provide licensing info and some sort of hardware summary info If everything is fine, the server returns some crucial missing parts of the program bound to that certain pc along with the usage limit of say 2 days That crucial stuff is not saved to hard drive, so it is downloaded every time the program starts, if the programm runs more than 2 days, data is downloaded again If the same info is used from different computers, suspend the customer account What do you think about this? It may seem a bit to restrictive, but I'd better make less sales at first then eventually see my precious killer app downloaded for free. Anyways, first I need some basic theory/tutorials/guides about how to ensure that user only uses a certain Java app if he has paid for it, so please suggest some. Thanks

  • Statically linked libraries not running code inside to setup static variables.

    - by MJD
    In a c++ project I am working on, I have a simple c++ file that needs to run some code at the beginning of the program execution. This file is linked into a static library, which is then linked into the main program. I have similar code in other files running fine, that looks something like: bool ____nonexistent_value = executeAction(); However, it does not work inside this file unless I make use of a function implemented in this file. It does work if the library is compiled as a shared library. I'd prefer to link this statically as the library is only a convenience as the file is in a different directory.

  • How can I find out how much memory an instance of a C++ class consumes?

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

  • When debugging in VS 2008 why does the debugger land on a second return statement?

    - by Hellfire
    When debugging the following console program: class Program { static void Main(string[] args) { Console.WriteLine(DoIt(false)); Console.WriteLine(DoIt(true)); } private static Boolean DoIt(Boolean abort) { try { throw new InvalidOperationException(); } catch(Exception ex) { if (abort) { return true; } Console.WriteLine("Got here"); return false; } } } Why does the IDE land on the second return statement during the second call to DoIt()? The results of the execution is correct but the debugging experience is misleading. Is this a known issue? Is the behavior in VS 2010 the same?

  • Call external library from PHP. What is faster: exec or extension?

    - by robusta
    Hi, I need to make calls from webpage to external library written in C++ and display the result. Platform is Linux, Apache, PHP. My current idea is to use PHP service which will call my library/program. I found that there are two possible ways to do this: 1) use PHP 'exec' function 2) write PHP extension I am curious what works more effective? Faster? Less load the server? I will probably need to do 4 calls per second, so I want to be as optimal as possible. P.S. If you are aware of some other (more effective) way of calling C++ library or program from webpage, please let me know. Thanks a lot, Robusta

  • How to controll (and emulate) monitor/projector on Linux?

    - by klew
    I would like to write some C/C++ program to controll monitor/projector attached to my computer. I've googled around, but I couldn't find almost anything that would lead me in some direction. Do you know where I can learn about it? What I would like to do is to write "Hello world" on an external monitor. It would be also nice to have some "monitor emulator" that will act as physicaly attached monitor (or to write program to emulate it). I'm not sure if it is possible. I couldn't find anything like this. I'm working on Ubuntu 9.10 with Gnome.

  • explain this macro

    - by deostroll
    #define __T(x) L ## x Found in code from one of the MFC source header file. It is mostly used for converting strings to ........ (I don't know what). If I am correct it converts strings to LPCTSTR...don't know what that type is either... I can't seem to convert char* into LPCTSTR. While MFC file handling, the following code will always return error while trying to open the file... char* filepath = "C:\\Program Files\\Microsoft Office\\Office12\\BITMAPS\\STYLES\\GLOBE.WMF"; if( !file.Open((LPCTSTR)filepath , CFile::modeRead, &fexp) ) { fexp.ReportError(); return 1; } But instead if I wrote it this way, it doesn't give error: if( !file.Open( _T("C:\\Program Files\\Microsoft Office\\Office12\\BITMAPS\\STYLES\\GLOBE.WMF") , CFile::modeRead, &fexp) ) { fexp.ReportError(); return 1; } I am looking at passing a variable as the first argument to the CFile::Open() method.

  • Strange python error

  • What's this UI pattern called?

    - by Bears will eat you
    I'm trying to figure out what this sort of thing is called, and eventually how I can create one in a web browser. It looks like this (screenshot of the first app that came to mind): The specific component/pattern I'm looking for is the two list boxes ("Included Gear" and "Excluded Gear") that represent inclusion/exclusion of items from a set. I'm not really looking for the WPF name (if there is one) but it might be helpful. I am looking for the name of this thingy, if there is one, and if you really want to make my day, you can point me toward a jQuery or YUI way of making one of these dealies in a browser. In case you were wondering, the screenshot is a World of Warcraft gear optimization program. Go figure why it was the first program that came to mind when I was trying to think of an example.
