• iPhone: Create a single UIView from multiple clicks

  - by Cuzog

  I'm making a partial overlay modal in my app with the code from “Semi-Modal (Transparent) Dialogs on the iPhone” at ramin.firoozye.com. In doing so, the button that calls the modal is still visible and clickable. I will hide this button when the modal spawns, but I want to be sure if the user clicks very quickly twice, a new modal doesn't come up for each click. What is the best way to check that the modal doesn't already exist when calling it from the button click? You can download the test project here. For those that don't have xcode, the relevant functions are below: I call forth the modal on button click with this: - (IBAction)displayModal:(id)sender { ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; modalController.view.frame = CGRectOffset(modalController.view.frame, 0, 230); [self showModal:modalController.view]; } Then use this function to animate the custom modal over the current view: - (void)showModal:(UIView*) modalView { UIWindow* mainWindow = (((TestAppDelegate*) [UIApplication sharedApplication].delegate).window); CGPoint middleCenter = modalView.center; CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); modalView.center = offScreenCenter; // we start off-screen [mainWindow addSubview:modalView]; // Show it with a transition effect [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; // animation duration in seconds modalView.center = middleCenter; [UIView commitAnimations]; } Then I dismiss the modal on button click with this: - (IBAction)dismissModal:(id)sender { [self hideModal:self.view]; } And then use these functions to animate the modal offscreen and clean itself up: - (void)hideModal:(UIView*) modalView { CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); [UIView beginAnimations:nil context:modalView]; [UIView setAnimationDuration:0.7]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(hideModalEnded:finished:context:)]; modalView.center = offScreenCenter; [UIView commitAnimations]; } - (void)hideModalEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { UIView* modalView = (UIView *)context; [modalView removeFromSuperview]; [self release]; } Any help is greatly appreciated!

• Negative number representation across multiple architechture

  - by Donotalo

  I'm working with OKI 431 micro controller. It can communicate with PC with appropriate software installed. An EEPROM is connected in the I2C bus of the micro which works as permanent memory. The PC software can read from and write to this EEPROM. Consider two numbers, B and C, each is two byte integer. B is known to both the PC software and the micro and is a constant. C will be a number so close to B such that B-C will fit in a signed 8 bit integer. After some testing, appropriate value for C will be determined by PC and will be stored into the EEPROM of the micro for later use. Now the micro can store C in two ways: The micro can store whole two byte representing C The micro can store B-C as one byte signed integer, and can later derive C from B and B-C I think that two's complement representation of negative number is now universally accepted by hardware manufacturers. Still I personally don't like negative numbers to be stored in a storage medium which will be accessed by two different architectures because negative number can be represented in different ways. For you information, 431 also uses two's complement. Should I get rid of the headache that negative number can be represented in different ways and accept the one byte solution as my other team member suggested? Or should I stick to the decision of the two byte solution because I don't need to deal with negative numbers? Which one would you prefer and why?

• Rails editing multiple records at once

  - by Joseph Silvashy

  I feel like this might be really simple but I'm just not getting it right, so I have like a settings page in my app and I want each setting to be like a key value store, for example: +-------------------+--------------------------------+ | setting | value | +-------------------+--------------------------------+ | twitter_username | something | +-------------------+--------------------------------+ | facebook_url | http://facebook.com/someguy | +-------------------+--------------------------------+ My form looks something like this: <% form_tag set_admin_settings_path, :method => :put do %> <ol> <% for setting in @settings %> <li class="field"> <label><%= setting.setting_name.humanize %></label> <%= text_field_tag "[setting_value][]", setting.setting_value %> </li> <% end %> <li class="submit"> <%= submit_tag "Update settings" %> </li> </ol> <% end %> Everything renders fine but when I try to save the form, nothing is saved :(

• Multiple grids in one area

  - by anon

  I'm currently creating a WPF application, using C# and XAML in Visual Studios 2010. I have a master grid. In that master grid I have a group bar which you can select different items. Depending on what you select, the middle of the master grid can be totally different. What I was wondering is, what's the best way to program the middle part? Right now, I have it set up in such a way that everything in the middle is dynamically programed in C#, and everything on the outside is programmed in XAML. In C# I programmed: for each group bar item, there is a grid that goes with it (so that different content can be displayed on it). Each grid is a child of the master grid. Each grid is visible or hidden when necessary. Is this the best way to approach this? The best example of this is in Outlook 2007, where you have your group bar on the right hand side. When you select different items on the group bar (mail, calendar, tasks) the right of the group bar completely changes.

• CUDA - multiple kernels to compute a single value

  - by Roger

  Hey, I'm trying to write a kernel to essentially do the following in C float sum = 0.0; for(int i = 0; i < N; i++){ sum += valueArray[i]*valueArray[i]; } sum += sum / N; At the moment I have this inside my kernel, but it is not giving correct values. int i0 = blockIdx.x * blockDim.x + threadIdx.x; for(int i=i0; i<N; i += blockDim.x*gridDim.x){ *d_sum += d_valueArray[i]*d_valueArray[i]; } *d_sum= __fdividef(*d_sum, N); The code used to call the kernel is kernelName<<<64,128>>>(N, d_valueArray, d_sum); cudaMemcpy(&sum, d_sum, sizeof(float) , cudaMemcpyDeviceToHost); I think that each kernel is calculating a partial sum, but the final divide statement is not taking into account the accumulated value from each of the threads. Every kernel is producing it's own final value for d_sum? Does anyone know how could I go about doing this in an efficient way? Maybe using shared memory between threads? I'm very new to GPU programming. Cheers

• Rails: remote_form_for not playing nicely with multiple submit_tags

  - by grifaton

  I have a form with the following: <% form_remote_tag :url => {:action => :wotsit} do %> <%= submit_tag "Foo" %> <%= submit_tag "Bah" %> <% end %> I would expect that the submitted parameters would reflect which button had been clicked. However, no matter which button I click, the submitted parameters include "commit"="Foo". What am I doing wrong?

• Multiple asserts in single test?

  - by Gern Blandston

  Let's say I want to write a function that validates an email address with a regex. I write a little test to check my function and write the actual function. Make it pass. However, I can come up with a bunch of different ways to test the same function ([email protected]; [email protected]; test.test.com, etc). Do I put all the incantations that I need to check in the same, single test with several ASSERTS or do I write a new test for every single thing I can think of? Thanks!

• Different actions on multiple Keydown event

  - by Billy Mitchell

  Okay, so my question (im hoping) is fairly simple. I want to know what to do so that I can create different events for the same keycode. For instance Id like to fade out a div and fade a new one in on the first keypress, then fade that one out and fade a new one in on keypress. Thanks! $(document).keydown(function() { if (event.keyCode == '40') { $('.div-1').fadeOut("slow") $('.div-2').fadeIn("slow") // I'd like this event to occur on the Second keydown $('.div-2').fadeOut("slow") $('.div-3').fadeIn("slow") } });

• validate uniqueness amongst multiple subclasses with Single Table Inheritance

  - by irkenInvader

  I have a Card model that has many Sets and a Set model that has many Cards through a Membership model: class Card < ActiveRecord::Base has_many :memberships has_many :sets, :through => :memberships end class Membership < ActiveRecord::Base belongs_to :card belongs_to :set validates_uniqueness_of :card_id, :scope => :set_id end class Set < ActiveRecord::Base has_many :memberships has_many :cards, :through => :memberships validates_presence_of :cards end I also have some sub-classes of the above using Single Table Inheritance: class FooCard < Card end class BarCard < Card end and class Expansion < Set end class GameSet < Set validates_size_of :cards, :is => 10 end All of the above is working as I intend. What I'm trying to figure out is how to validate that a Card can only belong to a single Expansion. I want the following to be invalid: some_cards = FooCard.all( :limit => 25 ) first_expansion = Expansion.new second_expansion = Expansion.new first_expansion.cards = some_cards second_expansion.cards = some_cards first_expansion.save # Valid second_expansion.save # **Should be invalid** However, GameSets should allow this behavior: other_cards = FooCard.all( :limit => 10 ) first_set = GameSet.new second_set = GameSet.new first_set.cards = other_cards # Valid second_set.cards = other_cards # Also valid I'm guessing that a validates_uniqueness_of call is needed somewhere, but I'm not sure where to put it. Any suggestions? UPDATE 1 I modified the Expansion class as sugested: class Expansion < Set validate :validates_uniqueness_of_cards def validates_uniqueness_of_cards membership = Membership.find( :first, :include => :set, :conditions => [ "card_id IN (?) AND sets.type = ?", self.cards.map(&:id), "Expansion" ] ) errors.add_to_base("a Card can only belong to a single Expansion") unless membership.nil? end end This works when creating initial expansions to validate that no current expansions contain the cards. However, this (falsely) invalidates future updates to the expansion with new cards. In other words: old_exp = Expansion.find(1) old_exp.card_ids # returns [1,2,3,4,5] new_exp = Expansion.new new_exp.card_ids = [6,7,8,9,10] new_exp.save # returns true new_exp.card_ids << [11,12] # no other Expansion contains these cards new_exp.valid? # returns false ... SHOULD be true

• Moving Multiple Divs With Same Class Inside Parent

  - by superzilla

  So, My website is hosted on enjin.com and when you give users a tag with an image it appears on the forums under their name, however it's a vertical list with the tag names. I want to organize it so all of the tag images appear on one line and all of the tag names appear on a horizontal list below it. They use div tags somewhat like this <div class="tag"> <div class="tag-image"></div> <!-- If the tag lacks an image this is excluded --> <div class="tag-text">Tag Name</div> <!-- If you want the name to be hidden this is excluded --> </div> They then pretty much repeat this for every tag. Somewhat the same thing is used for forum posts too. So, I want to move all the tag-image divs together on a single line and all of the tag-text divs down and give each it's own line. I only want to move them within their parent element (to avoid images/tags from one forum user from going to another). I know how to append things with jquery and have googled how to move elements around, but I'm afraid that they're all going to end up together under another user's avatar.

• UITableView section footer multiple UIButtons

  - by joec

  In the section footer of my UITableView, i have one UIButton, this button is 320 pixels wide (i.e. takes up full width of view). I would like two buttons in the section footer, but when i try and add another button, Interface Builder just puts it on top of the existing button. If i try to change the size in the inspector from 320 to say 50 pixels, it always reverts to 320. What am i doing wrong? Thanks.

• ColdFusion Session issue - multiple users behind one proxy IP -- cftoken and cfid seems to be shared

  - by smoothoperator

  Hi Everyone, I have an application that uses coldfusion's session management (instead of the J2EE) session management. We have one client, who has recently switched their company's traffic to us to come viaa proxy server in their network. So, to our Coldfusion server, it appears that all traffic is coming from this one IP Address, for all of the accounts of this one company.. Of the session variables, Part 1 is kept in a cflock, and Part 2 is kept in editable session variables. I may be misundestanding, but we have done it this way as we modify some values as needed throughout the application's usage. We are now running into an issue of this client having their session variables mixed up (?). We have one case where we set a timestamp.. and when it comes time to look it up, it's empty. From the looks of it this is happening because of another user on the same token. My initial thoughts are to look into modifying our existing session management to somehow generate a unique cftoken/cfid, or to start using jsession_ID, if this solves the problem at all. I have done some basic research on this issue and couldn't find anything similar, so I thought I'd ask here. Thanks!

• Using a singleton database class in functions and multiple scripts(PHP) - best use methods

  - by dscher

  I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

• Consuming WCF REST service in multiple ways (.Net, plain XML)

  - by Jan Jongboom

  I have become quite frustrated of WCF as I just want to use this simple scenario: Provide a webservice using REST, with a UriTemplate like /method/{param1}/{param2}/ and a 3th parameter that is sent to the service as XML as POST data. Use just plain XML, no SOAP overhead. Be able to generate a proxy in Visual Studio so a .Net using client can easily use the service (don't care about SOAP overhead here). I can create 1. and 2. but no way I can use 3. I tried adding both webHttpBinding and basicHttpBinding endpoints in my services config; I fooled around with the <services/> tag, but I just can't get this working. What am I missing here?! N.B. I checked out this article: http://stackoverflow.com/questions/186631/rest-soap-endpoints-for-a-wcf-service but nothing what is described there seems to work here?!

• GridView and multiple postbacks problem

  - by Jonn

  I have a grid view containing checkboxes and a great deal of problems surrounding it. First of all the page on_load and on_init gets called twice. The first call says it's a postback and the second isn't. If I check for postbacks, during the second call the change of state (i.e. A button_click event that was supposed to refresh the data in the grid) that triggered during the first call does not register. If I don't check for postbacks, checkboxes in the GridView do not retain its state by the second call to OnLoad/OnInit.
