• How to provide Input to Dialogs designed by Qt Designer

  - by GG

  Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements. I read http://doc.trolltech.com/4.5/designer-using-a-ui-file.html to use these GUI elements in my code and using multiple inheritance approach. I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

• Can FileOutputStream() take a relative path as an argument

  - by Ankur

  I am creating a FileOutputStream object. It takes a file or String as an argument in its constructor. My question is, can I give it a relative URL as an argument for the location of a file, it doesn't seem to work, but I am trying to work out if this is possible at all (if not I will stop trying). If it is not possible, how can I (from a servlet) get the absolute path (on the filesystem, not the logical URL) to the current location in such a way that I can pass that to the constructor. Part of my problem is that my dev box is Windows but I will publish this to a Unix box, so the paths cannot be the same i.e. on Windows C:/.... and on unix /usr/...

• How to use soap in javascript

  - by fresher

  Hi guys, I am trying to use SOAP in javascript but i am not getting how to start it. Here is the code sample i write in PHP and it works fine. I want to write this code in Javascript. In following code i call one api from a www.example.com and for calling certain api we require to pass some parameters. $soapClient = new SoapClient("https://www.example.com/abc.aspx?WSDL"); // Prepare SoapHeader parameters $param_sh = array( ); $header = new SoapHeader('http://somesite.com/action/', 'user_credential', $param_sh); // Prepare Soap Client $soapClient->__setSoapHeaders(array($header)); // Setup the RemoteFunction parameters $param = array( "pwd" => "password", "id" => "name" ); // Call RemoteFunction () $contents = $soapClient->__call("name_of_api",array($param)); print_r($contents); Thanx in advance!!!

• Python and urllib2: how to make a GET request with parameters

  - by Infinity

  I'm building an "API API", it basically a wrapper for a in house REST web service that the web app will be making a lot of requests to. Some of the web service calls need to be GET rather than post, but passing parameters. Is there a "best practice" way to encode a dictionary into a query string? e.g.: ?foo=bar&bla=blah I'm looking at the urllib2 docs, and it looks like it decides by itself wether to use POST or GET based on if you pass params or not, but maybe someone knows how to make it transform the params dictionary into a GET request. Maybe there's a package for something like this out there? It would be great if it supported keep-alive, as the web server will be constantly requesting things from the REST service. Thanks!

• validates_uniqueness_of...limiting scope - How do I restrict someone from creating a certain number

  - by bgadoci

  I have the following code: class Like < ActiveRecord::Base belongs_to :site validates_uniqueness_of :ip_address, :scope => [:site_id] end Which limits a person from "liking" a site more than one time based on a remote ip request. Essentially when someone "likes" a site, a record is created in the Likes table and I use a hidden field to request and pass their ip address to the :ip_address column in the like table. With the above code I am limiting the user to one "like" per their ip address. I would like to limit this to a certain number for instance 10. My initial thought was do something like this: validates_uniqueness_of :ip_address, :scope => [:site_id, :limit => 10] But that doesn't seem to work. Is there a simple syntax here that will allow me to do such a thing?

• Selectively prevent Session from being created

  - by Jean Barmash

  In my app, I have an external monitor that pings the app ever few minutes and measures its uptime / response time Every time the monitor connects, a new server session is created, so when I look at the number of sessions, it's always a minimum of 15, even during times where there are no actual users. I tried to address this with putting the session creation code into a filter, but that doesn't seem to do it - I guess session automatically gets created when the user opens the first page? all() { before = { if (actionName=='signin') { def session = request.session //creates session if not exists } } } I can configure the monitor to pass in a paramter if I need to (i.e. http://servername.com/?nosession, but not sure how to make sure the session isn't created.

• Compression Array of Bytes

  - by Pedro Magalhaes

  Hi, My problem is: I want to store a array of bytes in compressed file, and then I want to read it with a good performance. So I create a array of bytes then pass to a ZLIB algorithm then store it in the file. For my surprise the algorithm doesn't work well., probably because the array is a random sample. Using this approach, it will will be ber easy to read. Just copy the stream to memory, decompress them and copy it to a array of bytes. But i need to compress the file. Do I have to use a algorithm, like RLE, for compresse the byte array? I think that I can store the byte array like a string and then compress it. But i think I am going to have a poor performance on reading data. Sorry for my poor english. Thanks

• Is there a better way than #if DebugMode for logging

  - by Daniel

  I'm making a c++ library thats going to be P/Invoked from c#, so i am unable to breakpoint/debug the c++ side of things. So i decided to add logging so i can see if anything goes wrong and where it happens. I add a #define DebugMode 1 in order to determine if i am to log or not. First of all i'm not very good at c++ but i know enough to get around. So my questions are: Is there a better way than wrapping #if DebugMode #endifs around every Log call? I could simply do that inside the method and just return if logging isn't disabled but won't that mean then all those logging strings will be in the assembly? How can i emulate what printf does with its "..." operator enabling me to pass something like Log("Variable x is {0}", x); Thanks!

• Using read() directly into a C++ std:vector

  - by Joe

  I'm wrapping up user space linux socket functionality in some C++ for an embedded system (yes, this is probably reinventing the wheel again). I want to offer a read and write implementation using a vector. Doing the write is pretty easy, I can just pass &myvec[0] and avoid unnecessary copying. I'd like to do the same and read directly into a vector, rather than reading into a char buffer then copying all that into a newly created vector. Now, I know how much data I want to read, and I can allocate appropriately (vec.reserve). I can also read into &myvec[0], though this is probably a VERY BAD IDEA. Obviously doing this doesn't allow myvec.size to return anything sensible. Is there any way of doing this that 1) Doesn't completely feel yucky from a safety/C++ perspective and 2) Doesn't involve two copies of the data block - once from kernel to user space and once from a C char * style buffer into a C++ vector. Any thoughts collective?

• How do I get a scalar value from a stored proc using Nettiers

  - by Micah

  I have a really simple stored procedure that looks like this: CREATE PROCEDURE _Visitor_GetVisitorIDByVisitorGUID ( @VisitorGUID AS UNIQUEIDENTIFIER ) AS DECLARE @VisitorID AS bigint SELECT @VisitorID = VisitorID FROM dbo.Visitor WHERE VisitorGUID = @VisitorGUID --Here's what I've tried RETURN @VisitorID 'Returns an IDataReader SELECT @VisitorID 'Returns an IDataReader --I've also set it up with a single output --parameter, but that means I need to pass --the long in by ref and that's hideous to me I'm trying to get nettiers to generate a method with this signature: public long VisitorService.GetVisitorIDByVisitorGUID(GUID visitorGUID); Basically I want Nettiers to call ExecuteScalar instead of ExecuteReader. What am I doing wrong?

• iPhone OS: Posting an image + text "story" to a user's news feed through the facebook api

  - by nickthedude

  So what I am trying to do is post an image that has been created by a user on an iphone into that users newsfeed. The functionality I am having a hard time understanding if it is possible: Can I pass a local NSURL (or URL?)(to a png file that lives in the documents folder) through a JSON string and onto Facebook? i want to mimic the action of a user going to his/her facebook page, clicking into the textfield for their newsfeeld, uploading an image by clicking the "photos" icon and selecting an image from a local disk and uploading it. I would also like to add some text into the post optionally. I'm just getting started with the Facebook api and it seems pretty tough right now, any help would be appreciated. code examples appreciated. Thanks, Nick

• Asp .Net MVC Viewmodel should be class or struct?

  - by Jonas Everest

  Hey guys, I have just been thinking about the concept of view model object we create in asp.net MVC. Our purpose is to instantiate it and pass it from controller to view and view read it and display the data. Those view model are usually instantiated through constructor. We won't need to initialize the members, we may not need to redefine/override parameterless constructor and we don't need inheritance feature there. So, why don't we use struct type for our view model instead of class. It will enhance the performance.

• How to upload binary (audio) data from a Flash AS3 client to .NET server (WCF/REST/HTTP/?)?

  - by Bobby

  Simply stated: I'm trying to record audio in a browser, and get that data back up to the server. I originally tried to capture, encode and upload the audio using Silverlight, but because of the lack of suitable client-side encoding options, I'm now giving Flash a shot (Flash has baked-in support for encoding to Speex). I think I've figured out how to capture and encode the audio... But now what was easy in Silverlight, is the challenge in Flash. My server-side is .NET: MVC2- I'm open to receiving the audio in whatever manner is best- REST, WCF.. So that's my question: How could one upload binary data from Flash, to a .NET server-side endpoint. If the answer is WCF: then how would one setup the client-side proxies to communicate with the service? If the answer is REST or HTTP Post, then how would one construct this HTTP request and pass along the data? I've been reading up on AS3, but am new to Flash dev... Thanks for any help!

• Rails + Dragonfly gem: Saving image in a directory structure based on ActiveRecord object attributes

  - by Allen Bargi

  I'm using dragonfly gem to manage images and attachments in my rails app and I need to store images in a specific directory structure based on my user model. let' say I have user model which has a name and each user has many albums, which have a name also, then I want the images to be stored in "#{RAILS_ROOT}/public/system/#{user.name}/#{user.album.name}/#{suffix}" I've managed to changed the root_path in dragon fly and I even overrided relative_storage_path like this: class MyDataStore < Dragonfly::DataStorage::FileDataStore private def relative_storage_path(suffix) "#{suffix}" end end but still, I don't know how I can pass the ActiveRecord object attributes like user.name and user.album.name to relative_storage_path to create my ideal path. do you have any idea how I can do such a thing?

• WIX: Using a temporary file during install

  - by madbadger

  Hello! I am writing a WIX installer and I have a following requirement: During installation, I need to pass an absolute path to a file (lets call it A) included in my installer to a COM component, which already exists on the hard drive and is a part of another program. I have already written an appropriate Custom Action which expects a path to the file A. I don't want to include A as a file installed in the Program Files folder and removed during the uninstallation process. Instead, I would like to put A only temporary on the hard drive, call my Custom Action which will cause the COM component to use the content of A, and then remove A from disk. Is there an easy way to accomplish this goal? I have tried to utilize the Binary Table and store A there, however I don't know how to reference A using absolute path. I know I could put A outside of MSI file but I would like to keep every file installer needs in a single MSI. Any help would be appreciated.

• JQuery make an array - how/what is best

  - by russp

  I have 4 serailized arrays that I want to pass to php for processing. What is the best way to combine them into a single array example: serial_1 = $('#col1').sortable('serialize'); serial_2 = $('#col2').sortable('serialize'); serial_3 = $('#col3').sortable('serialize'); serial_4 = $('#col4').sortable('serialize');` each serialized array relates to a column/section of the page (col1,col2 etc.) What I need to do/would like to do is create a single array that puts the serialized array inside another array for a single post. example: var new_array = serilaize(col_1(serial_1),col2(serial_2),col3,(serial_3),col4(serial_4)) I KNOW THAT IS NOT RIGHT as I have no idea in JQuery how to right the correct syntax. This new array is to be posted via ajax like this: $.ajax({ url: "test.php", type: "post", data: new_array, error: function(){ alert('SOME ERROR MESSAGE'); } }); Thanks in advance

• setting actionscript 3 superclass variables

  - by jedierikb

  In AS3, if I have a class such: public class dude { //default value for a dude protected var _strength:Number = 1; public function dude( ):void { super( ); //todo... calculate abilities of a dude based on his strength. } } and a subclass public class superDude extends dude { public function superDude( ):void { _strength = 100; super( ); trace( "strength of superDude: " + _strength ); } } This will trace strength of superDude is 1. I expected the variable I set in the subclass (prior to calling the superclass constructor) to remain. Is there a way to assign class variables in subclass constructors which are not over-written by the superclass construtor? Or should I pass them up as constructor variables?

• Is there a programming language that performs currying when named parameters are omitted?

  - by Adam Gent

  Many functional programming languages have support for curried parameters. To support currying functions the parameters to the function are essentially a tuple where the last parameter can be omitted making a new function requiring a smaller tuple. I'm thinking of designing a language that always uses records (aka named parameters) for function parameters. Thus simple math functions in my make believe language would be: add { left : num, right : num } = ... minus { left : num, right : num } = .. You can pass in any record to those functions so long as they have those two named parameters (they can have more just "left" and "right"). If they have only one of the named parameter it creates a new function: minus5 :: { left : num } -> num minus5 = minus { right : 5 } I borrow some of haskell's notation for above. Has any one seen a language that does this?

• How to make GhostScript PS2PDF stop subsetting fonts

  - by gavin-softyolk

  I am using the ps2pdf14 utility that ships with GhostScript, and I am having a problem with fonts. It does not seem to matter what instructions I pass to the command, it insists on subsetting any fonts it finds in the source document. e.g -dPDFSETTINGS#/prepress -dEmbedAllFonts#true -dSubsetFonts#false -dMaxSubsetPct#0 Note that the # is because the command is running on windows, it is the same as =. If anyone has any idea how to tell ps2pdf not to subset fonts, I would be very greatful. Thanks --------------------------Notes ------------------------------------------ The source file is a pdf containing embedded fonts, so it is the fonts already embedded in the source file, that I need to prevent being subset in the destination file. Currently all source file embedded fonts are subset, in some cases this is not apparent from the font name, i.e it contains no hash, and appears at first glance to be the full font, however the widths array has been subset in all cases.

• The "correct" way to define an exception in Python without PyLint complaining

  - by Evgeny

  I'm trying to define my own (very simple) exception class in Python 2.6, but no matter how I do it I get some warning. First, the simplest way: class MyException(Exception): pass This works, but prints out a warning at runtime: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6 OK, so that's not the way. I then tried: class MyException(Exception): def __init__(self, message): self.message = message This also works, but PyLint reports a warning: W0231: MyException.__init__: __init__ method from base class 'Exception' is not called. So I tried calling it: class MyException(Exception): def __init__(self, message): super(Exception, self).__init__(message) self.message = message This works, too! But now PyLint reports an error: E1003: MyException.__init__: Bad first argument 'Exception' given to super class How the hell do I do such a simple thing without any warnings?

• How to clear cache for previously installed InfoPath forms on a client computer?

  - by user313067

  Hi folks, We recently had a strange issue with an InfoPath 2007 form being opened from SharePoint 2007 and receiving the error message "the system cannot find the file specified". To be clear, this was not a form services enabled form. Anyway, after spending way too much time trying to figure out what was going on (nothing in the MOSS 2007 server log files), we determined that the user had previously installed an older version of the form (but with the same name) on their workstation using a no longer available msi file (meaning we could not uninstall it from the workstation). So I wanted to pass on a very simple solution for anyone who is unfortunate to run into this problem in the future (since I lost a great deal of hair over it): Fire up regedit, go to HKEY_LOCALMACHINE-Software-Microsoft-Office-InfoPath-SolutionsCatalog. Locate the key that has the previously installed form name, and delete it. This will cause InfoPath to stop trying to open the form locally (which is either old or doesn't exist) and force it to open your form from SharePoint. Hope this helps someone!
