I have an app which list quotes and those quotes have a status (ex: accepted, rejected, on hold ..). I want the filter set on status='accepted' by default that is..

  • When machine code is generated from a program how does it translates to hardware level operations ??

    - by user553492
    Like if say the instruction is something like 100010101 1010101 01010101 011101010101. Now how is this translating to an actual job of deleting something from memory? Memory consists of actual physical transistors the HOLD data. What causes them to lose that data is some external signal? I want to know how that signal is generated. Like how some binary numbers change the state of a physical transistor. Is there a level beyond machine code that isn't explicitly visible to a programmer? I have heard of microcode that handle code at hardware level, even below assembly language. But still I pretty much don't understand. Thanks!

  • SVN: Recurisvely add files?

    - by Mark
    I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why? Is there a standard way to do this with other unix commands too? */*.py will nab a few more files, but it's kind of a pain in the butt to do this for every possible depth.

  • Is it possible to profile CPU / memory inside an Adobe AIR application?

    - by dain
    Couldn`t find any ActionScript native APIs even in the beta documentation, am I right supposing that this means the only way to measure CPU / memory consumption is by cooking up a custom native solution, hooking it up with AIR and making it work on each targeted platform? Basically the aim is to be able to have this information available inside AIR and not having to use an external application for profiling, not even Flex / Flash builder.

  • Magento - determine which xml layout file a page is using?

    - by John
    I tried reading the documentation but I still don’t really understand how magento's xml layout files work. In the directory app/design/frontend/default/modern/layout, i see a lot of xml files. How do I determine which xml file any given page on the website is using? For example, if I were on the home page at http://mysite.com, which layout xml file am I using? What if I’m on http://mysite.com/hello-world, which xml file then?

  • Out of Memory Matlab Error

    - by Hani
    Dears. I am using Matlab 2009b and having an out of memory error. I read other posted sol but they are not useful for me. I am sure that i am doing things right but i must use very huge amount of array sizes. I think that the problem lies beyond the fact that Matlab does not enable an array to be in more than one OS block. I am using Windows 7. Is there a way to get rid of this problem. For example can i increase the array block that Matlab uses in Windows 7? Thanks...Hani Almousli

  • How to span multile tables in Django

    - by ipartola
    The Django documentation gives en example like so: b = Blog.objects.get(id=1) b.entry_set.all() Which from what I understand results in 2 queries. What if I wanted to get the blog, the blog entries and all the comments associated with that entry in a number of queries that does not depend on the number of entries? Or do I have to drop down to SQL to do that?

  • How can I make external script output link to code in Visual Studio?

    - by JoelFan
    I sometimes need to search code for patterns in a way that goes beyond the regex capabilities of Visual Studio (e.g. patterns that depend on what was seen previously in the file or on the contents of other files). So I use Perl to analyze the source and output matching lines, along with the file name and line number. Since this is the exact same format as is produced by the search feature of Visual Studio, I wonder if there is a way to duplicate the functionality where I can double-click on a line and it will display that line in context in Visual Studio. Any ideas?

  • MSXML problem in VC++ 6

    - by Tony
    I have this bit of code: typedef CComQIPtr<MSXML::IXMLDOMDocument2> XML_DocumentPtr; then inside some class: XML_DocumentPtr m_spDoc; then inside some function: XML_NodePtr rn=m_spDoc->GetdocumentElement(); I cannot find anywhere in the MSDN documentation what that GetDocumentElement() is supposed to do? Can anyone tell me why it doesn't seem to be part of IXMLDOMDocument2 interface? And which interface does have it?

  • Flushing JDBC connection pools

    - by Matt
    Does anyone know the best (or any) way to flush a JDBC connection pool? I can't find anything obvious in the documentation. It appears connection pools aren't meant to ever be deleted. My current thought is to delete all DataSources from the hash we store them in, which will trigger our code to make new ones. However, my first attempt throws a ConcurrentModificationException.

  • Testcase with multitouch on Android?

    - by makke
    The TouchUtils class in the android documentation has functions like drag() [http://developer.android.com/intl/de/reference/android/test/TouchUtils.html#drag(android.test.InstrumentationTestCase,%20float,%20float,%20float,%20float,%20int)], but they do not support multi touch gestures, like a two finger swipe. Looking at the MotionEvent.obtain() methods, there does not seem to be any way of invoking a "virtual" multi touch event from a testcase. Anyone has got it working?

  • Why are configuration arrays acceptible parameters in PHP and Javascript?

    - by RenderIn
    In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

  • The Relationship Between Activities and View Objects - Android

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

  • Limitations in running Ruby on windows7

    - by orkutscraps
    n the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows7, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself?

  • 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)

  • admobad problem on iphone

    - by dubbeat
    Hey, I want to know if there's a few folks out there with experience in using admob for iphone apps. I've just started using it and have a problem. When I close an in app ad the actual ad itself has moved up 40 pixels and is mostly hidden behind the navigation bar. In addition all of my own content is shifted up 40 pixels. The addmob documentation is very limited so not much help there sadly.

  • Diff applications going crazy if the functions in the file were reordered

    - by VitalyB
    I've been busy refactoring a file in our project and as part of my changes I reordered the function to a more logical way. However, now when I'm trying to review my changes I get a mess: The diff applications has no idea that the functions were merely reordered and marks 80% of the file content as changed. I've tried to see the diff with both "Beyond Compare" and "WinMerge" to the same result. Is there some setting that might help me here? As tagged, I am using C# on Windows.
