  • C#: How to replace "-" with " -" only when it's not preceded by "e"?

    - by MaDDoX
    I imagine I should use Regex for that but I still scratch my head a lot about it (and the only similar question I found wasn't exactly my case) so I decided to ask for help. This is the input and expected output: Input: "c-0.68219,-0.0478 -1.01455-0.0441 0.2321e-4,0.43212" Output:"c -0.68219,-0.0478 -1.01455 -0.0441 0.2321e-4,0.43212" Basically I need either commas or spaces as value separators, but I can't break the exponential index (e-4). Maybe do two successive replacements?

  • tor api in own project

    - by Ockonal
    Hello, I'm going to develop gui-based application for tor controlling (like vidalia or torK). Are there any libraries for using tor? I don't want to parse each byte of information from sockets. My program should display branches of computers, use chosen as traffic-provider etc. What I need in my case? Are there any small and simple samples (for example open-source projects) to do this.

  • Using many mutex locks

    - by hanno
    I have a large tree structure on which several threads are working at the same time. Ideally, I would like to have an individual mutex lock for each cell. I looked at the definition of pthread_mutex_t in bits/pthreadtypes.h and it is fairly short, so the memory usage should not be an issue in my case. However, is there any performance penalty when using many (let's say a few thousand) different pthread_mutex_ts for only 8 threads?

  • Compiling in g++ for gprof

    - by myahya
    I do not understand the documentation for gprof regarding how to compile your program for profiling with gprof. In g++, is it required to compile with the -g option (debugging information) in a addition to the -pg option or not. In each case I get different results, and I would like to see where the bottlenecks in my application are in release mode, not in debug mode, where many optimizations are left out by the compiler (e.g. inlining)

  • Android moving back to first activity on button click

    - by cppdev
    I am writing a application where I am dealing with 4 activities, let's say A, B, C & D. Activity A invokes B, B invokes C, C invokes D.

How to simulate "home" button in this case ?

  • CSS: right wrapper dropping off the end of the page

    - by user310606
    I have an issue with a site I am working on where the right wrapper keeps dropping down below the site. Obviously I want it to stay on the right hand side. I've coded up a test case which shows my issue (I think) and I'm wondering if there is a better way to do things. The website url is http://www.musicworkshop.co.nz/ Below is the test case which (I think) is the cause of my issue, however it may not be. The pink box drops down if it does not fit within the page width. Is there a better way to do this? John <html> <head> <title> Test page </title> <link rel="stylesheet" href="test.css" type="text/css" /> </head> <body> <div id="superbox"> <div id="box1"> </div> <div id="box2"> </div> <div id="box3"> </div> <div id="box4"> </div> <div id="box5"> </div> <div id="box6"> </div> </div> </body> </html> #outsidebox{ width: 100%; } #superbox{ width: 1000px; height: 100px; margin: 0 auto; } #box1{ height: 100px; width: 200px; background: red; float: left; } #box2{ height: 100px; width: 200px; background: yellow; float: left; } #box3{ height: 100px; width: 200px; background: blue; float: left; } #box4{ height: 100px; width: 200px; background: green; float: left; } #box5{ height: 100px; width: 200px; background: grey; float: left; } #box6{ height: 100px; width: 200px; background: pink; float: left; }

  • Instantiating and referencing models in MVC

    - by fig-gnuton
    In MVC, should each model be a globally accessible singleton accessible to any view/controller? Or should the models be singletons that are dependency injected into any component that requires them? Or should a new model instance be created for each component that needs one, in which case events would be used to propagate changes across model instances of the same class?

  • What does the length attribute do when set on the @Column JPA annontation?

    - by James McMahon
    What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

  • Does the compiler optimize the function parameters passed by value?

    - by Naveen
    Lets say I have a function where the parameter is passed by value instead of const-reference. Further, lets assume that only the value is used inside the function i.e. the function doesn't try to modify it. In that case will the compiler will be able to figure out that it can pass the value by const-reference (for performance reasons) and generate the code accordingly? Is there any compiler which does that?

  • Implementing a kext that intercepts file system usage.

    - by UraN
    Hi, how do most of antivirus software block file system io in case of an infected file? I suppose all the magic resides in some custom kext to do that. Can anyone point me to some topics on this? Some working example would also be great. I've read apple docs about kext development, but mostly it's all about hardware drivers and i could not find what i need. Thanx.

  • Task Manager with Trac support for Mac

    - by Dmitry
    Found Mylyn as a very good task manager that supports Trac and Gmail Task. I've seen Tasktop, but looking for something with smaller memory footprint that I could always run in background. Is there any lighter client (not on Eclipse platform) to manager at least Trac tasks (via XML-RPC) and in best case scenario with GMail Tasks support?

  • What is the point of function pointers?

    - by gramm
    Hi, I have trouble seing the utility of the function pointers. I guess it may be useful in some cases (they exist, after all), but I can't think of a case where it's better or unavoidable to use a function pointer. Could you give some example of good use of function pointers (in C or C++)? Many thanks :)

  • How to recognize external hard drive from all local drives in .NET Framework?

    - by biajee
    I've already tried System.IO.DriveType. But it only provides to me with the information of whether it's a removable drive such as floppy disc or a USB flash drive. And a USB external hard drive will be recognized as a local non-removable drive in this case. Furthermore, since there are more than one kinds of external hard drive, for example, USB and IEEE 1394. It's really hard to figure it out from ports. Any information will be appreciated.
