  • Powershell equivilent of python's if __name__ == '__main__':

    - by Mark Mascolino
    I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

  • WPF custom user widgets. Will UI components be standardized?

    - by Andrew Florko
    There are lots of articles and video lessons that describe how to create your unique user widget (graphical control) with WPF. There are tons of technical details what is behind the scene and I feel people enthusiasm with ability to customize widgets as never before. I remember those days when VCL library (Delphi) appeared and there was the same enthusiasm in VCL widgets area. Ability to create VCL controls was nearly the must when you was applying for a job as Delphi developer. This situation continued for several years till professional sophisticated 3'd party UI libraries appeared. Hardly you'll have to create your own VCL widget nowadays. Will WPF widgets enthusiasm die as VCL one?

  • App Engine - Objectify - Storing a byte[]

    - by Spines
    I'm using the Objectify library for interfacing with the app engine datastore. In my User class, I store the hashed password as a byte[]. When I put it in the datastore, it is correctly stored as a blob. When I try to load the User object back out I get this error: java.lang.IllegalStateException: Cannot load non-collection value '<Blob: 40 bytes>' into private byte[] How do I fix this? Do I have to change my User class to have the hashed password be of type ShortBlob?

  • Can run Javascript but not jQuery?

    - by blazonix
    I'm running into a strange problem - I tried running a basic function in JS and jQuery, and while the former worked, the latter didn't. JS - okay alert('Works'); jQuery - not okay $(document).ready({ alert('Works'); }); Here's some facts: My references to the jQuery library are correct (And pretty sure my Internet connection is steady :) I'm using a CDN - CloudFlare to be exact, but I've switched development mode on and Rocket Loader off - so all the code I've uploaded to the server is WYSIWYG (CloudFlare adds some stuff in the tags if you leave Rocket Loader on. I tried running the alert code in the head section, and elsewhere in the body tags, to no avail. What could have possibly gone wrong?

  • What's the best way to share one Entity Framework 4 data model among multiple applications (meant to

    - by Ivan
    A project (a "solution" to say in VS terms) of mine consists of an ASP.Net 4 Dynamic Data Entities web application, some WinForms applications, some WPF applications, some services. All they are intended to work with one SQL Server database, generated from an Entity Framework 4 model as table-per-type, with lots of inheritance and multiple self-referencing relations. Where do I best put my model? In a separate class library, a copy in every project, in one project, etc. What naming should I best use? Is it good idea to name it MySolution.MyClassLibrary.MySolutionEntities, or just MySolutionEntities or just MySolution? Can you share any useful experience on this subject?

  • Can FLV AAC stream be played in Android

    - by HariKJ
    Hi, I'm trying to build a radio player and the client is providing a stream which is a FLV container with the audio being AAC When I read the headers it shows up as audio/aacp. I have tried all possible ways such as using the 1) Streaming through mediaplayer (Does not work) 2) Use the NPR mode of using a proxy stream (I get a broken pipe exception) 3) Play it in chunks ( Plays but I need the SDCard and the playback is not very great) 4) Use the GPL'd FAAD2 Library but I would have to pay the royalty fee Can some one help me out on figuring this issue out. The last option that I have is to have my client change the stream to mp3 container (which I know that it works) Regards, Hari

  • What's Your favorite f# use? where does f# makes life (a lot) easier (compared to c#)?

    - by luckyluke
    I've skimmed the stack and did not get the overflow as there is probably no such question. I'm just learning f# and I am A seasoned c# and .net dev. I am into financial apps and currently F# helps me a lot with maths calcs like zero finding or minimum finding (although I still want some good maths library there). I see that processing multiple items (files or smth) tends to be easier, but my GUI (web, win) are still c# based. I am in the team of 5 devs and we know that the new tool is out, we are learning it after hours (to pimp ourselves up) but maybe we shouldn't bash the door somebody already opened. So in business apps, whats Your first killer part of soft You would code in F# (if You could and would know IT would be easier, faster, more testable, easier to maintain etc.? Business rules? ImageProcessing? Data processing? hope it's not to subjective. luke

  • C++ -malign-double compiler flag

    - by Martin
    I need some help on compiler flags in c++. I'm using a library that is a port to linux from windows, that has to be compiled with the -malign-double flag, "for Win32 compatibility". It's my understanding that this mean I absolutely have to compile my own code with this flag as well? How about other .so shared libraries, do they have be recompiled with this flag as well? If so, is there any way around this? I'm a linux newbie (and c++), so even though I tried to recompile all the libraries I'm using for my project, it was just too complicated to recursively find the source for all the libraries and the libraries they're dependent on, and recompile everything.

  • How to set variable before callback is called?

    - by user1995327
    I'm trying to design a webpage... I have a function that I call get all info needed for an idividuals home page. A snippet of the codes is: exports.getHomePageData = function(userId, cb) { var pageData = {}; pageData.userFullName = dbUtil.findNameByUserId(userId, function(err){ if (err) cb(err); }); pageData.classes = dbUtil.findUserClassesByUserId(userId, function(err){ if (err) cb(err); }); cb(pageData); } The problem I'm having is the cb(pageData) is being called before I even finish setting the elements. I've seen that people use the async library to solve this but I was wondering if there was any other way for me to do it without needing more modules... Thanks!

  • Is there are standard way to store a database schema outside a python app

    - by acrosman
    I am working on a small database application in Python (currently targeting 2.5 and 2.6) using sqlite3. It would be helpful to be able to provide a series of functions that could setup the database and validate that it matches the current schema. Before I reinvent the wheel, I thought I'd look around for libraries that would provide something similar. I'd love to have something akin to RoR's migrations. xml2ddl doesn't appear to be meant as a library (although it could be used that way), and more importantly doesn't support sqlite3. I'm also worried about the need to move to Python 3 one day given the lack of recent attention to xml2ddl. Are there other tools around that people are using to handle this?

  • Fast exchange of data between unmanaged code and managed code

    - by vizcaynot
    Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.

  • When is @uncheckedVariance needed in Scala, and why is it used in GenericTraversableTemplate?

    - by retronym
    @uncheckedVariance can be used to bridge the gap between Scala's declaration site variance annotations and Java's invariant generics. scala import java.util.Comparator import java.util.Comparator scala trait Foo[T] extends Comparator[T] defined trait Foo scala trait Foo[-T] extends Comparator[T] :5: error: contravariant type T occurs in invariant position in type [-T]java.lang.Object with java.util.Comparator[T] of trait Foo trait Foo[-T] extends Comparator[T] ^ scala import annotation.unchecked._ import annotation.unchecked._ scala trait Foo[-T] extends Comparator[T @uncheckedVariance] defined trait Foo This says that java.util.Comparator is naturally contra-variant, that is the type parameter T appears in parameters and never in a return type. Which begs the question, why is it also used in the Scala collections library: trait GenericTraversableTemplate[+A, +CC[X] <: Traversable[X]] extends HasNewBuilder[A, CC[A] @uncheckedVariance] What are the valid uses for this annotation?

  • qTip with jQuery dialogs

    - by MikeWyatt
    I'm using qTip to show validation errors in a grid. The tooltip appears after a failed row save and doesn't disappear until the row is resaved or the changes are canceled. The problem with this is that opening a dialog while the tooltip is visible causes the tooltip to be rendered on top of the dialog. That is because the z-index is hard-coded to 6000+ for all tooltips, while jQuery dialogs are set to 1000+. I could fix this problem by changing the hard-coded value in qTip to <1000, but then tooltips fired from the dialog will appear behind the dialog. Is there anything I can do, aside from changing the qTip code or using a different tooltip library?

  • Combining multiple UIImageViews and preserve resolution

    - by plspl
    I am designing an application where a user places multiple UIImageViews one over another. When the user decides to save this to photo album, I have to combine all these UIImageViews and save it to Photo Library. While combining them I need to preserve their positions, resolutions, zorder. The approach I tried I was to have a parent UIView which acts like a container. The user places all the UIImageViews inside this UIView. While saving, I take a screenshot of the UIView and save it. Although this approach works, it does not preserve the resolution. The resolution of the final image is same as the resolution of the parent UIView size (width and height being 300 pixels). Is there way to preserve the resolution? or atleast have a higher resolution like upto 1024* 1024 pixels? Any pointers/code examples would be appreciated!

  • How to make Visual C++ 9 not emit code that is actually never called?

    - by sharptooth
    My native C++ COM component uses ATL. In DllRegisterServer() I call CComModule::RegisterServer(): STDAPI DllRegisterServer() { return _Module.RegisterServer(FALSE); // <<< notice FALSE here } FALSE is passed to indicate to not register the type library. ATL is available as sources, so I in fact compile the implementation of CComModule::RegisterServer(). Somewhere down the call stack there's an if statement: if( doRegisterTypeLibrary ) { //<< FALSE goes here // do some stuff, then call RegisterTypeLib() } The compiler sees all of the above code and so it can see that in fact the if condition is always false, yet when I inspect the linker progress messages I see that the reference to RegisterTypeLib() is still there, so the if statement is not eliminated. Can I make Visual C++ 9 perform better static analysis and actually see that some code is never called and not emit that code?

  • Can StructureMap be configured so that one can use different .config settings based on whether the p

    - by Mark Rogers
    I know that in StructureMap I can read from my *.config files (or files referenced by them), when I want to pass specific arguments to an object's constructor. ForRequestedType<IConfiguration>() .TheDefault.Is.OfConcreteType<SqlServerConfiguration>() .WithCtorArg("db_server_address") .EqualToAppSetting("data.db_server_address") But what I would like to do is read from one config setting in debug mode and another in release mode. Sure I could surround the .EqualToAppSetting("data.db_server_address"), with #if DEBUG, but for some reason those statements make me cringe a little when I put them in. I'd like to know if there was some way to do this with the StructureMap library itself. So can I feed my objects different settings based on whether the project is built in debug or release mode?

  • Reusability, testability, code complexity reduction and showing-off-ability programming importance

    - by Andrew Florko
    There are lots of programming and architecture patterns. Patterns allow to make code cleaner, reusable, more testable & at last (but not at least) to feel the follower a real cool developer. How do you rank these considerations for you? What does affect you most when you decide to apply pattern? I wonder how many times code reusability (especially for MVP, MVC patterns) was important? For example DAL library often shared between projects (it's reusable) but how often controllers/views (abstracted via interfaces) are reused?

  • API For Flex Apps To Interact

    - by dimo414
    I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

  • authorization services question cocoa

    - by Marius
    Sorry for being a total beginner in cocoa and for asking the following stupid question, but it's too confusing for me to google it myself or maybe i'm just missing something. I need to run a shellscript with elevated privileges in cocoa. As i understand, "AuthorizationExecuteWithPrivileges" is the correct way to do it. So i've created an application and tried to use some code from one example i found online. The problem is ... if i understand it correctly ... there should be a Security framework in /System/Library/Frameworks that i have to import to the project, but ... it's not there. What am i missing here? Thank you.

  • How do I link a VS2008 C++ project as a DLL instead of a LIB?

    - by Clark Battle
    I have the C++ source code in a Visual Studio project from another developer that compiles into a static lib. I need to change it so that it builds a dll from that code so that I can call it from C#. I went into the project properties in Visual Studio and changed the configuration type to a DLL. However, it now gives lots of linker errors like: error LNK2001: unresolved external symbol __CAP_Enter_Function XXXFilter.obj XXXFramework What else do I need to do in Visual Studio and in the code to produce a dll from the code instead of a lib? The library is huge so writing a wrapper is not an option. I have the code so I should be able to make it build a dll. I am not a very experienced C++ dev but I am in C# and visual studio. Thanks
