• Adding on touch event to images inside gridview

  - by Steve

  I have a gridview where each item has a image and a textview (an app), i added the onItemClick to the gridview in order to launch the app, i also removed the orange selection and made selector in xml so when pressed the text would change to grey and on release it would return to white. My problem is that i need the image to apply an alpha value when pressed and restore the previous alpha on release i tested a lot of ways and none did worked correctly. I came close with the updated answer from the autor of the question: How to set alpha value for drawable in a StateListDrawable?, but some how the state pressed never gets called, i don´t know if this is because i am using the onitemClick to launch the app or not. Also i since i can´t define the alpha on imageview xml i don´t know what else to do Any help will be appreciated

• Can I extends a sub class of Proxy class?

  - by KCBérenger

  I want to create a complete (and real) 2-dimensional array. In order to use a maximum of Adobe code, I want to use ListCollectionView which can manage sort and filters. But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

• How to update content of one ArrayController from the selected value of another ArrayController in Ember.js

  - by CodeHugger

  I have the following problem in ember.js. A child controller depends on a selected value in a parent controller in order to determine its content. In the database a child has a parent_id reference. App.parentsController = Em.ArrayController.create({ content: [], selected: null }); App.sonsController = Em.ArrayController.create({ // the value of content depends on the id of // the selected item in the parentsController content: [], selected: null }); App.daughtersController = Em.ArrayController.create({ // the value of content depends on the id of // the selected item in the parentsController content: [], selected: null }); I would prefer to solve this without the parentsController having to know anything about the other controllers. This should be possible with observers, bindings or even through calculations but I have no clue where to start. Any help would be well appreciated.

• Porting VS2005 project to VS2008

  - by lucavb

  i need to port a VS2005 Project (.NET2) to a VS2008 (.NET3.5) (or to VS2010 .NET4 not yet defined). The project is composed by: resources and configuration files (VS project files, like: .settings .vbproj .myapp .config .xconfig .Designer.vb); a lot of VB codes; xsc, xsd, xss and xsx files; a lot of Crystal reports for VS2005; graphical resources. The application take data in order to generate reports from more DB SQL Server 2005 istances. What is the best way to approach to a migration activity? Is there an internal migration tool? If yes, what's the best practice to use it? Which kind of files will be automatically ported to the new VS version? Thanks in advance for all the provided information

• Why do I have to explicitly cast sometimes for varargs?

  - by Daniel Lew

  I've got a Class that uses reflection a lot, so I wrote a method to help out: private <T> T callMethod(String methodName, Class[] parameterTypes, Object[] args) { try { Class c = mVar.getClass(); Method m = c.getMethod(methodName, (Class[]) parameterTypes); return (T) m.invoke(mVar, args); } // Insert exception catching here [...] } This worked well for any method that had parameters, however I had to explicitly cast parameterTypes to Class[] in order for this to work for methods with no parameters (e.g., callMethod('funName', null, null);). I've been trying to figure out why this is the case. It seems to me that if parameterTypes, when null, had no concept of what type it is (Class[]), then I'd need to cast it for getMethod(). But if that's the case, why is getMethod() able to tell the difference between null, and (Class[]) null when the method is invoked?

• Applying transformations to NSBitmapImageRep

  - by Adam

  So ... I have an image loaded into an NSBitmapImageRep object, so I am able to examine the contents of specific pixels via a two dimensional array. Now I want to apply a couple of "transformations" to the image, in preparation for some additional processing. If I was manipulating the image manually, in Photoshop, I would: Rotate the image Crop a portion of it and discard the rest Apply a "threshold" transformation (which essentially converts the image to black and white, based on the threshold value I provide) Resample the image to shrink it down a bit (which, although losing some image quality, will speed up the subsequent processing) (not necessarily in that order) Are there objective C methods available to facilitate these specific image manipulations, with the data in the NSBitmapImageRep object? If so, can someone point me to some good examples?

• RSpec View testing: How to modify params?

  - by sebastiangeiger

  I am trying to test my views with RSpec. The particular view that is causing me troubles changes its appearance depending on a url parameter: link_to "sort>name", model_path(:sort_by => 'name') which results in http://mydomain/model?sort_by=name My view then uses this parameter like that: <% if params[:sort_by] == 'name' %> <div>Sorted by Name</div> <% end %> The RSpec looks like this: it "should tell the user the attribute for sorting order" do #Problem: assign params[:sort_for] = 'name' render "/groups/index.html.erb" response.should have_tag("div", "Sorted by Name") end I would like to test my view (without controller) in RSpec but I can't get this parameter into my params variable. I tried assign in all different flavours: assign[:params] = {:sort_by => 'name'} assign[:params][:sort_by] = 'name' ... no success so far. Every idea is appreciated.

• How does one refer to the game1 class's variables in XNA

  - by user1149068

  I try to refer to an array in the Game1 class by creating an object of the Game1 class with its definition Game1 gameObject; , its declaration gameObject = new Game1(); in the constructor, and its usage gameObject.tileArray[xInt, yInt].treed = true;. The game1 class itself remains unchanged in its class code other than some methods and variables. When I try to use this code in the TreeRegion class it gives me "Object reference not set to an instance of an object," leading me to believe that the game1 class is null somehow. How might one change the class or object in order to refer to game1's variables? Mind you I am self-taught and still rather new to C#. The class that refers to game1: http://pastebin.com/0chEcKfq Game1 itself http://pastebin.com/zLDVzCca

• How to determine the date that Office 2003 was installed

  - by GalleySlave

  Is there any guaranteed way of determining the date that Office 2003 (and .Net Framework v2.0) were installed on a client computer? I am trying to nail down a problem which I think is due to the order that the .Net Framework and Office 2003 were installed in, so I need a way I can get a client to have a look at their machine (preferably the file system) and let me know. It may require admin privileges (or Registry etc) which wouldn't be a problem but not the preferred solution. It appears that the folders under Program Files\Microsoft Office\Office11 have a number with the same date which at first sight appear to be an installation date / time. Likewise in Windows\Microsoft.Net\Framework\v2.0.50727 there are two with the same date, but this seems less certain. I could use WMI with a winmgmts:object and SELECT * FROM Win32_Product, but was wondering if there was a 'telephone' way to do it!

• C++ Vector at/[] operator speed

  - by sub

  In order to give functions the option to modify the vector I can't do curr = myvec.at( i ); doThis( curr ); doThat( curr ); doStuffWith( curr ); But I have to do: doThis( myvec.at( i ) ); doThat( myvec.at( i ) ); doStuffWith( myvec.at( i ) ); (as the answers of my other question pointed out) I'm going to make a hell lot of calls to myvec.at() then. How fast is it, compared to the first example using a variable to store the result? Is there a different option for me? Can I somehow use pointers? When it's getting serious there will be thousands of calls to myvec.at() per second. So every little performance-eater is important.

• Max. # of printers allowed for google cloud print

  - by user1858673

  I intend to write an online shopping program using PHP. When the buyer completes an order I want to print the receipt to his/her printer using Google Cloud Print. For that I will need the buyer to shared his/her printer with my Google account. My questions are: 1. Is there an upper bound for the number of printers a Google account is allowed to print to? 2. Is there a daily upper bound for the number of print jobs a Google account is allow? Thanks for reading and thanks for the answers in advance.

• Experiences teaching or learning map/reduce/etc before recursion?

  - by Jay

  As far as I can see, the usual (and best in my opinion) order for teaching iterting constructs in functional programming with Scheme is to first teach recursion and maybe later get into things like map, reduce and all SRFI-1 procedures. This is probably, I guess, because with recursion the student has everything that's necessary for iterating (and even re-write all of SRFI-1 if he/she wants to do so). Now I was wondering if the opposite approach has ever been tried: use several procedures from SRFI-1 and only when they are not enough (for example, to approximate a function) use recursion. My guess is that the result would not be good, but I'd like to know about any past experiences with this approach.

• Cocoa Interface Builder object initialization

  - by Stanley

  Base on the documentation and sample code that I have gone through, I got an impression that when a class defined in xcode is read into and configured in Interface Builder, an object based on the class is effectively created and stored in an xib or nib file. So the object is ready to be used when the corresponding application is launched. Alternatively, for classes that have not been handled by Interface Builder, code such as the "new" statements have to be written in xcode explicitly in order for the associated objects to be created and used. It will be very nice to have people who are more knowledgable than me to confirm or to correct my very naive understanding of Interface Builder ...

• Query Execution Plan - When is the Where clause executed?

  - by Alex

  I have a query like this (created by LINQ): SELECT [t0].[Id], [t0].[CreationDate], [t0].[CreatorId] FROM [dbo].[DataFTS]('test', 100) AS [t0] WHERE [t0].[CreatorId] = 1 ORDER BY [t0].[RANK] DataFTS is a full-text search table valued function. The query execution plan looks like this: SELECT (0%) - Sort (23%) - Nested Loops (Inner Join) (1%) - Sort (Top N Sort) (25%) - Stream Aggregate (0%) - Stream Aggregate (0%) - Compute Scalar (0%) - Table Valued Function (FullTextMatch) (13%) | | - Clustered Index Seek (38%) Does this mean that the WHERE clause ([CreatorId] = 1) is executed prior to the TVF ( full text search) or after the full text search? Thank you.

• Is there any way to print the actual query that mysqli->execute() makes?

  - by 0plus1

  I have a complex query that gets executed like this: if ($stmt = $dbi->prepare($pt_query)) { $stmt->bind_param('ssssssssi', $snome,$scognome,$ssocieta,$svia,$slocalita,$sprovincia,$scap,$stelefono,$sfax,$uid); $stmt->execute(); echo $dbi->error; $stmt->close(); } else { printf("Error -> %s\n", $dbi->error); } This thing is failing without any error, it simply doesn't update the database. Since there is a ton of data that gets treated before this thing I would like to know if there is any way to show the actual query that mysqli is executing in order to understand where the problem is. Thank you.

• How to inflate a view in a determined position?

  - by Tivie

  I have an activity with an "Add" and a "Delete" button. The "Add Button" inflates a view, the "Delete Button" removes a selected View. When I inflate a view with the "Add Button", it is automatically drawn below any previously infalted view. I would like to give the user the possibility to move each inflated view up and down, so he could change the order they are show in screen (in a drag'n'drop kind of effect) +---------------------+ +---------------------+ | +-----------------+ | | +-----------------+ | | | View 1 | | | | View 2 | | | +-----------------+ | | +-----------------+ | | | --> | | | +-----------------+ | | +-----------------+ | | | View 2 | | | | View 1 | | | +-----------------+ | | +-----------------+ | +---------------------+ +---------------------+ Is it possible to specify the "position" in which each view is inflated? (for instance, below or above the currently selected view?) If not, what is the best way to accomplish the desired effect? (feel free to ask for any piece of code, if you think it might help)

• What is the most elegant way to deal with sourced files that themselves source (relative) source fil

  - by René Nyffenegger

  I am editing a file like /path/to/file.txt with vim, hence the current directory is /path/to. Now, I have a directory /other/path/to/vim/files that contains sourceA.vim. Also, there is a sourceB.vim file in /other/path/to/vim/files/lib/sourceB.vim In sourceA.vim, I want to source sourceB.vim, so I put a so lib/sourceB.vim into it. Now, in my file.txt, I do a :so /other/path/to/vim/files/sourceA.vim which fails, because the sourcing system is obviously not prepared for relative path names along with sourcing from another directory. In order to fix this, I put a execute "so " . expand("<sfile>:p:h") . "/lib/sourceB.vim" into sourceA.vim which does what I want. However, I find the solution a bit clumsy and was wondering if there is a more elegant solution to it. I cannot put the sourceA.vim nor sourceB.vim into vim's plugin folder.

• tiled images in swing

  - by sasquatch90

  I have task to prepare two windows with swing. One contains grid of squares, with random numbers in them. In second I need to load pieces of tiled image and then show them in the correct order, forming tiled image. Windows should look like this : http://img535.imageshack.us/img535/3129/lab8a.jpg Okay so how to bite this ? I've used swing only few times to draw some 2d polylines, so basically I just theoretically now what to do. Ok, so window number 1: I start with creating Jframe for the window. Then I do for loop and in it create 16 JLabels with random numbers in them ? How to set margins between each tile and the whole window ? Window number 2 : So I start the same, but instead of loading numbers I add images ? Now, how can I load image from file and then set it as background ?

• Howto disable the emacs site-start files permanently?

  - by elemakil

  When solving this problem I figured out that I need to disable the site-wise init files in order to get my emacs + CEDET running (everything works nicely when starting emacs using emacs --no-site-file but is broken without the additional argument). I'd like to disable the site-wise init files permanently but as I'm using several different approaches/methods when launching emacs (launcher/panel/terminal) I don't think aliasing it in my .zshrc won't work. I require a method to permanently disable all site-start files. Is there any easy way to achieve this? Thanks!

• Select only the first rows for each unique value of a column in R

  - by dmvianna

  From a dataframe like this test <- data.frame('id'= rep(1:5,2), 'string'= LETTERS[1:10]) test <- test[order(test$id), ] rownames(test) <- 1:10 > test id string 1 1 A 2 1 F 3 2 B 4 2 G 5 3 C 6 3 H 7 4 D 8 4 I 9 5 E 10 5 J I want to create a new one with the first appearance of each id / string pair. If sqldf accepted R code within it, the query could look like this: res <- sqldf("select id, min(rownames(test)), string from test group by id, string") > res id string 1 1 A 3 2 B 5 3 C 7 4 D 9 5 E Is there a solution short of creating a new column like test$row <- rownames(test) and running the same sqldf query with min(row)?

• Reference Parameters in C++: VERY basic example please.

  - by Sagistic

  I am trying to understand how to use reference parameters. There are several examples in my text, however they are too complicated for me to understand why and how to use them. Could anyone give me the MOST basic example of how/why to use one, and perhaps the difference with or without it (what would happen if you didn't attach the '&'). for example, if I've created a function: int doSomething(int& a, int& b), what would be the consequences of not putting in that '&.' I understand that reference variables are used in order to change a formal-reference, which then allows a two-way exchange of parameters. However, that is the extent of my knowledge, and a more concrete example would be of much help. Thank you.
