    - by Jon Hatfield

  • Directory Seperator ¥ for japaneses OS

    - by Vinay Pandey
    Hi All, I have an application written in asp.net that I am accessing from a machine with Japanese OS, I use FileUpload component on a page and file path comes as C:\Directory\AnotherDirectory\FileName where it should have been C:¥Directory¥AnotherDirectory¥FileName because ¥ is separator for Japanese OS. Any Idea how this can be fixed or any solution that you would recommend.

  • spin_lock_irqsave vs spin_lock_irq

    - by cojocar
    On a SMP machine we must use spin_lock_irqsave and not spin_lock_irq from interrupt context. Why would we want to save the flags (which contains the IF)? Is there another interrupt routine that could interrupt us? The flags are per CPU?

    - by Banani
    Hi!, I have setup svnserve server (1.6.5,plain, without apache) on Fedora. I start the svnserve with the command 'svnserve -d --foreground --listen-port=3690 -r /usr/local/svn-repos/proj-test' When user trying to checkout working copy from the local machine with command 'svn checkout svn://127.0.0.1/proj-test' gets following error svn: URL 'svn://127.0.0.1/proj-test' doesn't exists but, 'svn checkout svn://localhost/proj-test' works. I am curious to know why using 127.0.0.1 with svn:// fails? Thanks. Banani

  • Java embedded applet page security, how to properly meet its recquirements?

    - by meds
    If I have an applet embedded in a webpage and I want it to connect to server side software (also written in Java) how can I do this properly on a windows machine running local host? Would I have to run the java application from within the localhost directory and access the applet html from a browser (i.e. localhost/applet.html)? From what I undestand if you don't have everything setup correctly you won't be able to connect because of Java's security requirements. Thanks for any help :)

  • How to implement tail calls in a custom VM

    - by DeadMG
    How can I implement tail calls in a custom virtual machine? I know that I need to pop off the original function's local stack, then it's arguments, then push on the new arguments. But, if I pop off the function's local stack, how am I supposed to push on the new arguments? They've just been popped off the stack.

  • Save file as - dialog box with dynamic data

    - by MichaelMcCabe
    I know that this question is quite common, but its specifics are stumping me. I have an "export" button which I want to take a load of data generated, create a CSV file, then pop up a Save File As dialog box, to save that file on their local machine. The name of this file is dynamic, also. I know how to make the CSV file, but how do I then pop up a box on the client side to let the user download it? I am using JSP with Struts

  • Stored Procedure could not be found

    - by Beatles1692
    We use SQL server 2008 as our RDBMS and we have a database that has a different user rather than dbo as its owner. The problem is in one machine a stored procedure can not run unless its owner is mentioned. If we connect to our database using this user and try to execute the following : exec ourSP we get a "could not find ourSP" error but this works fine: exec user.ourSP Does anybody knows what can lead to such a strange behavior?

  • openmp sections running sequentially

    - by chi42
    I have the following code: #pragma omp parallel sections private(x,y,cpsrcptr) firstprivate(srcptr) lastprivate(srcptr) { #pragma omp section { //stuff } #pragma omp section { //stuff } } According to the Zoom profiler, two threads are created, one thread executes both the sections, and the other thread simply blocks! Has anyone encountered anything like this before? (And yes, I do have a dual core machine).
