  • How to check Linux version with Autoconf?

    - by Goofy
    My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features). I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm: Run "uname --release" and store output Parse output and subtract Linux version number (MAJOR.MINOR.MICRO) Compare version I don't know how to run command, store output and parse it. Maybe such macro already exists and it's available (I haven't found any)?

  • Visual Studio soft-crashing when encountering XAML Errors in initialize.

    - by Aren
    I've been having some serious issues with Visual Studio 2010 as of late. It's been crashing in a peculiar way when I encounter certain types of XAML errors during the InitializeComponent() of a control/window. The program breaks and visual studio gears up like it's catching an exception (because it is) and then stops midway displaying a broken highlight in my XAML file with no details as to what is wrong. Example: There is not pop outs, or details Anywhere about what is wrong, only a callstack that points to my InitializeComponent() call. Now normally I'd just do some trial and error to fix this problem, and find out where i messed up, but the real problem isn't my code. Visual Studio is rendered completely useless at this point. It reports my application still in "Running" mode. The Stop/Break/Restart buttons on the toolbar or in the menus don't do anything (but grey out). Closing the application does not stop this behaviour, closing visual studio gets it stuck in a massive loop where it yells at me complaining every file open is not in the debug project, then repeats this process when i have exausted every open file. I have to force-close devenv.exe, and after this happening 3-4 times in a row it's a lot of wasted time (as my projects are usually pretty big and studio can be quite slow @ loading). To the point Has anyone else experienced this? How can I stop studio from locking up. Can I at LEAST get information out of this beast another way so i can fix my XAML error sooner rather than after 3-4 trial-and-error compiles yielding the same crash? Any & All help would be appreciated. Visual Studio 2010 version: 10.0.30319.1RTM Edit & Update FWIW, mostly the errors that cause this are XamlParseExceptions (I figured this out after i found what was wrong with my XAML). I think I need to be clearer though, Im not looking for the solution to my code problem, as these are usually typos / small things, I'm looking for a solution to VStudio getting all buggered up as a result. The particular error in the above image that 100% for sure caused this was a XamlParseException caused by forgetting a Value attribute on a data trigger. I've fixed that part but it still doesn't tell my why my studio becomes a lump of neutered program when a perfectly normal exception is thrown in the parsing of the XAML. Code that will cause this issue (at least for me) This is the base template WPF Application, with the following Window.xaml code. The problem is a missing Value="True" on the <DataTrigger ...> in the template. It generates a XamlParseException and Visual Studio Crashes as described above when debugging it. Final Notes The following solutions did not help me: Restarting Visual Studio Rebooting Reinstalling Visual Studio

  • In Java What is the guaranteed way to get a FileLock from FileChannel while accessing a RandomAcces

    - by narasimha.bhat
    I am trying to use FileLock lock(long position, long size,boolean shared) in FileChannel object As per the javadoc it can throw OverlappingFileLockException. When I create a test program with 2 threads lock method seems to be waiting to acquire the lock (both exclusive and non exclusive) But when the number threads increases in the acutal scenario over lapping file lock exception is thrown and processing slows down due the block at File lock table. What is the best way to acquire lock avoiding the OverlappingFileLockException ?

  • Removing file locks in Windows and Java

    - by Jack
    I have a Java program that opens a file using the RandomAccessFile class. I'd like to be able to rename that file while it is opened by Java. In Unix, this isn't a problem. Does anyone know how I can do this in Windows? Should I set Java to open it a certain way? Thanks in advance.

  • AcroPDF in Delphi - How do I scroll?

    - by Liezzzje
    Hi, I'm currently adding a PDF viewer in a Delphi program using TAcroPDF. My problem is, the touch screens that need to show the PDF are rather small, so I wanted to add bigger buttons for scrolling. I thought I could use the function ScrollBy(DeltaX, DeltaY), but the function scrolls the component within it's container in stead of scrolling the document itself. Is there some way to scroll the PDF document?

  • getting started with Google Closure if you don't care about minifying/compiling?

    - by Tim
    If you don't care about minifying your code, is there a way to get started using the Google Closure library without having to set up a subversion client and use the compiler? The Notepad sample program on Google's website refers to <script src="closure-library/base.js" > </script > Can you simply download closure-library/base.js somewhere and start playing with the UI examples? The Closure Lite quick-start version doesn't appear to include goog.ui

    With the recent SEC proposal requiring that most Asset-Backed Securities issuers file a python computer program to document the flow of funds (or waterfall) provisions of the transaction, I thought it timely to ask what you thought the "Must-Have" Python Packages for Finance would be. PS: apart from answering here, please also consider answering this survey.

  • Redirecting multiple stdouts to single file

    - by obvio171
    I have a program running on multiple machines with NFS and I'd like to log all their outputs into a single file. Can I just run ./my_program >> filename on every machine or is there an issue with concurrency I should be aware of? Since I'm only appending, I don't think there would be a problem, but I'm just trying to make sure.

  • Robust and easy to implement serial bus (automotive application)

    - by JcMaco
    What serial communication bus would you use in a automotive embedded system if your main selection criteria were: * Electrically robust * Slow speed (32 kb/s) * Easy to program * Easy to interface with microcontrollers It won't be transferring much data, but it will need to be transferred periodically at high speed (100 - 500 Hz). I find that RS-232 is just not reliable enough if you have noise in your ground line. CAN-bus seems interesting, but I have no experience with it. We are currently interested in a combination of AVR AT90CAN128 microcontrollers.

  • Activity in Android

    - by leduchuy89vn
    Normally, a Java p'rogram starts from an object, then that object will create some GUI objects (window) and call the "Show" method So, is there any way to do the same thing in Android, since, by default in Android, a program runs from an object created by a class which extended from Activity class?

    I tried to convert a project that relies on the vjs runtime to vs2010, but it errors out when trying to run. It's giving the error that "Could not load file or assembly 'vjslib' or one of its dependencies. An attempt was made to load a program with an incorrect format." I reinstalled the vjs runtime, but it didn't seem to help. Is there any way to get get .net 4 to work with this? Thanks!

  • Anchor Window to Screen Edges in C#/WPF

    - by Kirk
    I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?
