  • How to log in to a website using installed twill?

    - by brilliant
    Hello, everybody!!!! I have just successfully installed TWILL on my computer with the help of one very supportive member of "StackOverflow" (you can check it out HERE) and have tried to run one of the simple examples on the twill documentation page (you can see that page HERE). Here is that example: Let's say my username on www.slash.org is lynxye and my password is mammal. When I try to enter that example code into my Python prompt, I can only type and enter the first line of the code because when I click on "Enter" to start a new line, I get some error messages right away: The same happens when I try to enter this code into my terminal: I think I miss out on some basics here. Perhaps, I need to create a file that would contain that code and then run that file somehow, but I really don't know where I need to create that file and with what extensdion. Can anyone, please, help me with this?

  • Using malloc/free in Objective-C object

    - by Itamar Katz
    I have a class AudioManager with a member of type AudioBufferList *. (This is a struct declared in the CoreAudio framework). Since AudioBufferList is not a NSObject, I cannot retain it, so I have to alloc/free it (correct me if I'm wrong). My question is, where is the 'right' place to free it? Currently I am doing it in the dealloc method of AudioManager. If I understand correctly, this method is invoked automatically once the release message is sent to the instance of AudioManager --- is that true? Is there any other recommended practice regarding using alloc/free on non-objects members of Objective-C objects? Edit: From Apples documentation: Subclasses must implement their own versions of dealloc to allow the release of any additional memory consumed by the object—such as dynamically allocated storage for data or object instance variables owned by the deallocated object. After performing the class-specific deallocation, the subclass method should incorporate superclass versions of dealloc through a message to super: Which makes things a little bit clearer - but more insights are appreciated.

  • Inherit a parent class docstring as __doc__ attribute

    - by Reinout van Rees
    There is a question about Inherit docstrings in Python class inheritance, but the answers there deal with method docstrings. My question is how to inherit a docstring of a parent class as the __doc__ attribute. The usecase is that Django rest framework generates nice documentation in the html version of your API based on your view classes' docstrings. But when inheriting a base class (with a docstring) in a class without a docstring, the API doesn't show the docstring. It might very well be that sphinx and other tools do the right thing and handle the docstring inheritance for me, but django rest framework looks at the (empty) .__doc__ attribute. class ParentWithDocstring(object): """Parent docstring""" pass class SubClassWithoutDoctring(ParentWithDocstring): pass parent = ParentWithDocstring() print parent.__doc__ # Prints "Parent docstring". subclass = SubClassWithoutDoctring() print subclass.__doc__ # Prints "None" I've tried something like super(SubClassWithoutDocstring, self).__doc__, but that also only got me a None.

  • How to define clock input in Xilinx

    - by seventeen
    Hey, I have almost no experience with Xilinx. I have a group project for a Digital Logic course that is due soon, where my partner, who was supposed to take care of the Xilinx simulations decided to bail on me. So here I am trying to figure it out last minute. I have designed a synchronous counter using a few JK Flip Flops and I need to define the CLK input for the FJKCs. I have drawn up the correct schematic, but I cannot figure out how to define a clock input. Any help appreciated, and yes, this is homework. I just can't find any basic xilinx documentation/tutorials online and I honestly don't have time to learn the whole IDE.

  • Zend RegEx Validator error message issue

    - by Mallika Iyer
    Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

  • Is there a difference between boost iostream mapped file and boost interprocess mapped file?

    - by Yijinsei
    I want to create a mapped binary file into memory; however I am not sure how to create the file to be mapped into the system. I read the documentation several times and realize there are 2 mapped file implementations, one in iostream and the other in interprocess. Do you guys have any idea on how to create a mapped file into shared memory? I am trying to allow a multi-threaded program to read an array of large double written in a binary file format. Also what is the difference between the mapped file in iostream and interprocess?

  • Arguments On a Console eMbedded Visual C++ Application

    - by Nathan Campos
    I'm trying to develop a simple application that will read some files, targeted for Windows CE. For this I'm using Microsoft eMbedded Visual C++ 3. This program(that is for console) will be called like this: /Storage Card/Test coms file.cmss As you can see, file.cmss is the first argument, but on my main I have a condition to show the help(the normal, how to use the program) if the arguments are smaller than 2: if(argc < 2) { showhelp(); return 0; } But when I execute the program on the command-line of Windows CE(using all the necessary arguments) I got the showHelp() content. Then I've checked all the code, but it's entirelly correct. But I think that eVC++ don't use argc and argv[] for arguments, then I want some help on how to determine the arguments on it.

  • How to pass -f specdoc option through rake task

    - by dorelal
    I am using rails 2.3.5 .rake spec works fine. This is from spec --help. spec --help -f, --format FORMAT[:WHERE] Specifies what format to use for output.

  • Libqxt under Qt Creator

    - by I'm Dario
    I want to create a tiny app which needs global shortcuts. So, I have downloaded the current version of libqxt (0.5.1) and opened as a project in Qt Creator. Libqxt compiles without problems in this way, so I thought that adding this in the tab Dependencies of my project it would get added automatically in the build, like Eclipse does with JAR libraries (I know that are different IDEs but it seems to be a common feature among them). What happens? Qt Creator compiles qxt before my project, when needed, but when I want to include its headers Qt Creator keeps warning me that it cannot find them. Probably I am missing the correct name of headers (I tried the headers showed in qxt documentation: http://doc.libqxt.org/0.5.0/classQxtGlobalShortcut.html) By the way, I looked the code for global shortcuts and I think I can rip it out and use it in my app as is and I am going to credit qxt team and open the code of my app.

  • WWSAPI and setting "soapenv:Header" values

    - by Ben Burnett
    I'm trying to connect to a web service from a C++ app using WWS. I got the base connection working just fine. My XML message has two parts though, a header (soapenv:Header) and a body (soapenv:Body). the generated functions only fill in the body. How do I set the Header information? I assumed it has something to do with WsSetHeader() or WsAddCustomHeader() but can't seam to find the right values to use in the parameters. Can someone point me in the right direction here? I've been googling and trying to research this now for several days and am finding many sources for basic help with WWSAPI, but nothing seams to go deeper into how to use it for more advanced applications. any good links or resources to find more advanced help on WWSAPI? Thanks, --Ben Burnett www.burnett.ws

  • ExtJs: Tree: how download then select using AJAX calls ?

    - by Olivier Pons
    Hi, Here's my goal : - open a tree - download the root nodes - expand automatically one specific node using AJAX (and loop n times here) until i find a leaf then select the leaf Here's the function that works when I declare the Tree : listeners: { load: function(n) { console.log('load(n)'); n.eachChild( function(n) { if ((n.id=='lys/2007') || (n.id=='lys/2007/08') || (n.id=='lys/2007/08/29')) { n.expand(false,false); } }); } } But if I don't know how to make it more "generic" (almost exactly like the ExtJs documentation). But they don't jump automatically to a specific node (i.e. I want no user interaction). Any idea / advice how to do this? Don't hesitate to edit my post to make it proper English :)

  • pip requirements.txt with alternative index

    - by piquadrat
    I want to put all the requirements of a repoze Zope2 install in a pip requirements file. Most of the repoze packages don't seem to be on PyPi, but there's an alternative PyPi index for them here. But I can't figure out how to tell pip to use that index together with a requirements file. For single packages, it's easy pip install zopelib -i http://dist.repoze.org/zope2/2.10/simple/ I tried the following pip install -r requirements.txt -i http://dist.repoze.org/zope2/2.10/simple/ or in my requirements.txt all kind or permutations of these: zopelib -i http://dist.repoze.org/zope2/2.10/simple/ zopelib --index http://dist.repoze.org/zope2/2.10/simple/ -i http://dist.repoze.org/zope2/2.10/simple/ zopelib or (because the documentation says "Note that all these options must be on a line of their own.") --index http://dist.repoze.org/zope2/2.10/simple/ zopelib So, what's the correct way of telling pip to use http://dist.repoze.org/zope2/2.10/simple/ as index?

  • TextToSpeech setOnUtteranceCompletedListener always returns -1 error?

    - by Robert Nekic
    I've been working with Android's TTS functions with general success however, one piece of it refuses to work for me; I can not successfully assign an OnUtteranceCompletedListener to my TextToSpeech object. I've tried implementing OnUtteranceCompletedListener in one of my classes and I've tried creating a new, stand-alone OnUtteranceCompletedListener instance. Both approaches are simple enough to implement and appear to yield proper listeners without exceptions...yet setOnUtteranceCompleteListener(myListener) ALWAYS returns -1 (ERROR). The documentation for this seems straight forward. Has anyone gotten this to work? I'm targeting SDK 4. Are there known issues with this with SDK4/v1.6?

  • Exposing.NET assembly as COM 101

    - by Jan Zich
    I have trouble to expose a .NET assembly in COM. It seems that I must be missing some basic step because I think I followed all tutorials and documentation I found as well as common sense, but still when I do (in a test VBScript): Set o = CreateObject("MyLib.MyClass") It keeps saying that the object cannot be created. Here are the steps I have done: I have simple one method dummy class with no attributes. The class is in a class library which has "Make assembly COM-visible" ticked in Visual Studio. The class library is signed. The DLL is registered via RegAsm.exe with the /codebase parameter (I don’t want / cannot add the DLL to GAC). Just to be sure, I tried to copy the library to the same directory as the test VBScript, but it does not help. Edit: I should have mentioned that the I can instantiate the class in COM if I put the DLL into GAC.

  • Static initializer in Java

    - by Szere Dyeri
    My question is about one particular usage of static keyword. It is possible to use static keyword to cover a code block within a class which does not belong to any function. For example following code compiles: public class Test { private static final int a; static { a = 5; doSomething(a); } private static int doSomething(int x) { return (x+5); } } If you remove the static keyword it complains because the variable a is final. However it is possible to remove both final and static keywords and make it compile. It is confusing for me in both ways. How am I supposed to have a code section that does not belong to any method? How is it possible to invoke it? In general, what is the purpose of this usage? Or better, where can I find documentation about this?

  • How prevalent is the use of Emacs' eshell in multi-platform development?

    - by pajato0
    I've only recently become aware of Emacs' eshell tool. It looks quite powerful in that it is entirely written in Emacs Lisp and does not require native subshell support. The Emacs info documentation is a bit sparse but EmacsWiki has pretty decent information, at least on a first glance. Given the potential value of eshell as a scripting tool/programmer's aid that works equally well on multiple platforms I'm wondering how prevalent the use of eshell versus the normal (bash) shell is among software developers. Would those of you who have taken the time to learn it recommend it or is it one of those many interesting ideas that did not really pan out?

  • what is the difference

    - by veilig
    I'm not even sure what this is called? But I'm trying to learn what the difference is between writing a function like this is in plpgsql: CREATE OR REPLACE FUNCTION foo() RETURNS TRIGGER AS $$ .... $$ LANGUAGE plpgsql; vs CREATE OR REPLACE FUNCTION foo() RETURNS TRIGGER AS $foo$ .... $foo$ LANGUAGE plpgsql; is there a difference when using $$ vs $foo$? why would someone choose one over another? perhaps I've just missed some documentation explaining the difference. If someone could enlighten me, I'd really appreciate it.

  • How can I put all twill commands together into one piece of code in a .py file?

    - by brilliant
    Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

  • Preventing referenced assembly PDB and XML files copied to output

    - by Jason Morse
    I have a Visual Studio 2008 C#/.NET 3.5 project with a post build task to ZIP the contents. However I'm finding that I'm also getting the referenced assemblies' .pdb (debug) and .xml (documentation) files in my output directory (and ZIP). For example, if MyProject.csproj references YourAssembly.dll and there are YourAssembly.xml and YourAssembly.pdb files in the same directory as the DLL they will show up in my output directory (and ZIP). I can exclude *.pdb when ZIP'ing but I cannot blanket exclude the *.xml files as I have deployment files with the same extension. Is there a way to prevent the project from copying referenced assembly PDB and XML files?
