  • Viewing large XML files in eclipse?

    - by Paul Wicks
    I'm working on a project involving some large XML files (from 50MB to over 1GB) and it would be nice if I could view them in eclipse (simple text view is fine) without Java running out of heap space. I've tried tweaking the amount of memory available to the jvm in eclipse.ini but haven't had much success. Any ideas?

  • VB6: Slow Binary Write?

    - by Tom the Junglist
    Wondering why a particular binary write operation in VB is so slow. The function reads a Byte array from memory and dumps it into a file like this: Open Destination For Binary Access Write As #1 Dim startP, endP As Long startP = BinaryStart endP = UBound(ReadBuf) - 1 Dim i as Integer For i = startP To endP DoEvents Put #1, (i - BinaryStart) + 1, ReadBuf(i) Next Close #1 For two megabytes on a slower system, this can take up to a minute. Can anyone tell me why this is so slow?

  • Is it a good practice to always use smart pointers ?

    - by Dony Borris
    Hi, I find smart pointers to be a lot more comfortable than raw pointers. So is it a good idea to always use smart pointers? ( Please note that I am from Java background and hence don't much like the idea of explicit memory management. So unless there are some serious performance issues with smart pointers, I'd like to stick with them. ) Any advice would be greatly appreciated. Thanks.

  • What the best multi-thread application debugger for C++ apps.

    - by Coredumped
    I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

  • SSIS Migration - Pulling IDs from dest DB?

    - by TheSciz
    So I'm working on migrating some data to a new server. In the new server, each entry in the MAIN table is assigned a new GUID when the transfer takes place. A few other tables must be migrated, and their records must link to the GUID in the MAIN table. Example... WorksheetID --- GUID 1245677903 --- 1 AccidentID --- WorksheetID --- Guid 12121412 --- 1245677903 --- 1 The guid is used moreso for versioning purposes, but my question is this. In SSIS, is there any way to pull the Worksheet's GUID from the destination database and assign it directly to the entries in the 'Accident' table? Or do I have to just dump the data into the source DB and run some scripts to get everything nicely referenced? Any help would be greatly appreciated.

  • Hardest concept to grasp as a beginner

    - by noizetoys
    When you were starting to program, what was the hardest concept for you to grasp? Was it recursion, pointers, linked lists, assignments, memory management? I was wondering what gave you headaches and how you overcame this issue and learned to love the bomb, I mean understand it. EDIT: As a followup, what helped you grok your hard-to-grasp concept?

  • Light Weight repalcement to GNOME for Ubuntu

    I am working on rolling a bit of my own version of linux for my real time car application. I plan to base it off of minimal ubuntu (only needsd 32 MB of memory). I am not the most skilled person with linux so not really sure how to assess components when adding them to my system. What I am looking for is a lightweight windows manager to replace gnome and it has to support the gtkmm library. Does anyone know of one?

  • Is there a work around for setAppCacheEnabled on WebView for an Android 2.1 application causing the

    - by Kevin
    We have an HTML 5.0 web application that we ported to Android. It's our intention to run this in a Native Wrapper. Our application uses the ApplicationCache to run offline. This works find when running under the browser. While being hosted in a WebView within a native application, after the last file is downloaded and stored in the ApplicationCache from the manifest the application is terminated and does a core dump. This appears to be a documented bug. http://code.google.com/p/android/issues/detail?id=7939 Has anyone doing anything similar found a work around for this issue?

  • Possible reasons and resolutions for time out

    - by ming yeow
    I cannot SSH into my instance - Operation timed out. What could be the reasons why, and what can I do to resolve it? Rebooting normally takes a long time to take effect, and might just makes things worst UPDATE: It is not about permissions - i can log in normally just fine. I suspect it might be because of memory issues

  • Log your SQL in Rails application inside unit test

    - by Phuong Nguy?n
    I want to install a logger so that I can dump all executed SQL of my rails application. Problem is, such logger is associated with AbstractAdapter which initialized very soon under test mode, and thus cannot be set by my initializer code. I try to put ActiveRecord::Base.logger = MyCustomLogger.new(STDOUT) in the end of environment.rb like someone advised but it only works when being run in console environment (kicked by script/console), not when run under test mode. I wonder if there is any way to config such logger so that I will sure to be invoked under any environment (test, development, production, console)

  • How can you prevent a window being captured by Print-Screen?

    - by John
    I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

  • Creating installers in .net

    - by Manish
    I want to create a installer which would just dump few files and folders at a location specified by user. But the problem is these files are required to be picked up from a fixed source folder and then the installer is build. Also, these files may change any time and then again a new version of the installer is required to be created. I want to do this in .Net using Setup and Deployment project. I'm not sure how to do this. Do I need to create another class library project with a Setup Poject? Does anyone has any idea?

    - by mrbunyrabit
    First i thought that i had to convert javascript to php, but then i found out that cant because of server and client side executions. So now I simply want to send ONE variable <script type="text/javascript"> function scriptvariable() { var theContents = "the variable"; } </script> to a php variable <?php $phpvariable ?> That function in the javascript executes when lets say i click on a button. Now i have Nooo idea how to get that phpvariable Equal to the javascript one so i can use that phpvariable to look up stuff in my Database. I know i can add it to my url or some thing, and just refresh the page.. But id like to do it with AJAX as further in my webpage i might have to use this Ajax method.. So is there an easy way to do this without having to dump pages of code on my page to do one simple thing?

  • Unable to debug St9bad_alloc error. Tried reducing the size of the data structure, error still persists

    - by timtowtdi
    I get a St9bad_alloc error which I'm unable to debug. I tried reducing the size of the data structure to eliminate the possibility that I might be running out of memory but that doesn't seem to be the case. These are the relevant files:- gdb backtrace: http://pastebin.com/5hFhHXnL TraceCache.cc: http://pastebin.com/j8vK812j I can't understand how, in the backtrace it jumps from TraceCache.cc:55 to TraceCache.cc:34 whereas in my code I can't see any such path. Please let me know in case any other information is required. Thanks
