  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

    - by James Trusler
    I have been trying for... about 4 hours now lmao. currentCalc returns 50 currentSum returns 0 when i alert them. Yet I cannot add them together with parseInt???? what am i doing wrong :'( var identRow = $('tr.identRow'); identRow.each( function(){ var getIdentClass = $(this).attr('class').split(' ').slice(1); $('tr.ohp' + getIdentClass + ' td.EURm').each( function(index){ var currentCalc = parseInt($(this).text().replace('.',''), 10); var currentSum = $('tr.' + getIdentClass + ' td.totalEURm', this).text().replace('.',''); total = parseInt(currentCalc, 10) + parseInt(currentSum, 10); $('tr.' + getIdentClass + ' td.totalEURm').text(total); if (index==6){ alert(total); } } ); } );

  • Global variables in hadoop.

    - by Deepak Konidena
    Hi, My program follows a iterative map/reduce approach. And it needs to stop if certain conditions are met. Is there anyway i can set a global variable that can be distributed across all map/reduce tasks and check if the global variable reaches the condition for completion. Something like this. While(Condition != true){ Configuration conf = getConf(); Job job = new Job(conf, "Dijkstra Graph Search"); job.setJarByClass(GraphSearch.class); job.setMapperClass(DijkstraMap.class); job.setReducerClass(DijkstraReduce.class); job.setOutputKeyClass(IntWritable.class); job.setOutputValueClass(Text.class); } Where condition is a global variable that is modified during/after each map/reduce execution.

  • An error occurred loading a configuration file: Failed to start monitoring changes because the netwo

    - by Josh Stodola
    This error just started happening this morning in one particular project. When I try to publish the site it gives me this error and I can't complete the publish! Sometimes restarting Visual Studio magically fixes the problem, but it will just appear again later. Not only that, when I restart VS I lose all my "undo capabilities". There is a KB article on the subject, but it did not help. What can I do to stop this very annoying problem once and for all?

  • C#: How to constuct a variable from another variables

    - by ozzwanted
    How to construct new variable in C#. I mean, to have sth like this public void updateXXX(string endingOfVariable, int newValue) { this.textBox_{endingOfVariable} = newValue; } This is implemented in Php: $a = 'var'; $b = 'iable'; $variable = 'var'; echo ${$a.$b}; But maybe it is possible in C#. The problem is that - I created ~500 textBoxes in C# Windows Form, and if I want to set a value, I need to build a switch() {case:; } statment with 500's cases.

  • how to exchange variables between extern iframe and site

    - by helle
    hey guys, for developement reasons (working with facebook-connect) i put the connect iframe in an iframe. on that way i am able to work on the connect-thing independent of my ip and don't have to develop on the live-server. the iframe holding the connect-button iframe is on my server, accessing the same db-server as the developer version (developer version is running on localhsot). as far as good ... BUT how can i let the parent site know, that the user has connected, so that i get his profile-picture displayd as reaction to this? how can i react in generally on an action/event/JS in an iframe? is there a way? can the iframe post data to the parent site? like a time-stamp and fb_userid? if the iframe stuff doesn't work ... i thougt of saving the ip to the fb_userid (to db) and check matches ... but i don't like this idea.

  • Multiple flash video players on w3c-valid page is slow

    - by vect
    I have a web site that displays a column of flash videos. The page is w3c-valid. The problem is that the page loads very slowly and sometimes crashes my web browser. Until the page is fully loaded, the videos are slow to respond and play. Is there a way to make these videos load their preview images only? What should I do to speed the page up? The videos are 360x264.

  • Rails 3 fields_for agressive loading?

    - by Seth
    Hi all, I'm trying to optimize (limit) queries in a view. I am using the fields_for function. I need to reference various properties of the object, such as username for display purposes. However, this is a rel table, so I need to join with my users table. The result is N sub-queries, 1 for each field in fields_for. It's difficult to explain, but I think you'll understand what I'm asking if I paste my code: <%= form_for @election do |f| %> <%= f.fields_for :voters do |voter| %> <%= voter.hidden_field :id %> <%= voter.object.user.preferred_name %> <% end %> <% end %> I have like 10,000 users, and many times each election will include all 10,000 users. That's 10,000 subqueries every time this view is loaded. I want fields_for to JOIN on users. Is this possible? I'd like to do something like: ... <%= f.fields_for :voters, :joins => :users do |voter| %> ... <% end %> ... But that, of course, doesn't work :(

  • Codeigniter PHP - loading a view at an anchor point

    - by James Billings
    I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.

  • How to mock static member variables

    - by pkrish
    I have a class ClassToTest which has a dependency on ClassToMock. public class ClassToMock { private static final String MEMBER_1 = FileReader.readMemeber1(); protected void someMethod() { ... } } The unit test case for ClassToTest. public class ClassToTestTest { private ClassToMock _mock; @Before public void setUp() throws Exception { _mock = mock(ClassToMock.class) } } When mock is called in the setUp() method, FileReader.readMemeber1(); is executed. Is there a way to avoid this? I think one way is to initialize the MEMBER_1 inside a method. Any other alternatives? Thanks!

  • Loading GWT Messages from a Database

    - by Lars Tackmann
    In GWT one typically loads i18n strings using a interface like this: public interface StatusMessage extends Messages { String error(String username); : } which then loads the actual strings from a StatusMessage.property file: error=User: {0} does not have access to resource This is a great solution, however my client is unbendable in his demand for putting the i18n strings in a database so they can be changed at runtime (though its not a requirement that they be changed realtime). One solution is to create a async service which takes a message ID and user locale and returns a string. I have implemented this and find it terribly ugly (and it introduces a huge amount of extra communication with the server, plus it makes property placeholder replacement rather complicated). So my question is this, can I in some nice way implement a custom message provider that loads the messages from the backend in one big swoop (for the current user session). If it can also hook into the default GWT message mechanism, then I would be completely happy (i.e. so I can create a interface like above and keep using the the nice {0}, {1}... property replacement format). Other suggestions for clean database driven messages in GWT are also welcome.

  • Loading specific files from arbitrary directories?

    - by Haydn V. Harach
    I want to load foo.txt. foo.txt might exist in the data/bar/ directory, or it might exist in the data/New Folder/ directory. There might be a different foo.txt in both of these directories, in which case I would want to either load one and ignore the other according to some order that I've sorted the directories by (perhaps manually, perhaps by date of creation), or else load them both and combine the results somehow. The latter (combining the results of both/all foo.txt files) is circumstantial and beyond the scope of this question, but something I want to be able to do in the future. I'm using SDL and boost::filesystem. I want to keep my list of dependencies as small as possible, and as cross-platform as possible. I'm guessing that my best bet would be to get a list of every directory (within the data/ folder), sort/filter this list, then when I go to load foo.txt, I search for it in each potential directory? This sounds like it would be very inefficient, if I have dozens of potential directories to search through every time. What's the best way to go about accomplishing this? Bonus: What if I want some of the directories to be archives? ie. considering both data/foo/ and data/bar.zip to both be valid, and pull foobar.txt from either one without caring.

  • How to name variables which are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

  • Objective C instance variables - Newbie

    - by Dwayne King
    OK - so I'm sure my confusion here is just a result of being stuck in a "Java mindset" and not understanding how Obj C differs in this case. In Java, I can declare a variable in a class, like this, and each instance of that class will have it's own: MyClass { String myVar; MyClass() { // constructor } } In Obj C I tried to do the same thing by declaring a variable only in the .m file like this: #import "MyClass.h" @implementation MyClass NSString *testVar; @end My expectation here was that this variable has a scope limited to this class. So I created a second class (identical): #import "MySecondClass.h" @implementation MySecondClass NSString *testVar; @end What I'm seeing (and has me baffled) is that changing the variable in one class, affects the value seen in the other class. In fact, if I set a breakpoint, and then "Jump to Definition" of the variable, it takes me to th I've created an extremely small XCode project that demonstrates the problem here Nothing more humbling than moving to a new language :) Thanks in advance.

  • chrome extension script is loading twice even more on some pages

    - by Youhan
    this is my background.js file chrome.tabs.onUpdated.addListener(function(tabId,info, tab) { var sites =new Array('site2','site1'); var url=tab.url; var siteFlag=0; for(var i in sites) { var regexp = new RegExp('.*' + sites[i] + '.*','i'); if (regexp.test(url)) {siteFlag=1;} }; if(siteFlag==1){ chrome.tabs.executeScript(tabId, {file:"contentscript.js"}); chrome.tabs.executeScript(tabId, {file:"jquery.js"}); chrome.tabs.insertCSS(tabId,{file:"box.css"}); } }); In the contentscript.js I simply run a popup box. $(document).ready(function () { function popup() {...} if (window.addEventListener) { window.addEventListener('load', popup(), false); } else if (window.attachEvent) { window.attachEvent('onload', popup()); } }); There are some pages that there are one popup-box and there are pages that two or even more what is the problem?

  • How to sub with matched groups and variables in Python

    - by Syed
    Hi, new to python. This is probably simple but I haven't found an answer. rndStr = "20101215" rndStr2 = "20101216" str = "Looking at dates between 20110316 and 20110317" outstr = re.sub("(.+)([0-9]{8})(.+)([0-9]{8})",r'\1'+rndStr+r'\2'+rndStr2,str) The output I'm looking for is: Looking at dates between 20101215 and 20101216 But instead I get: P101215101216 The values of the two rndStr's doesn't really matter. Assume its random or taken from user input (I put static vals here to keep it simple). Thanks for any help.

  • Loading more than 10 images on iPhone??

    - by SeniorLee
    I'm trying to add more than 10 pictures on ScrollView. NSUInteger i; for (i = 1; i <= numberOfImage; i++) { NSString *imageName = [NSString stringWithFormat:@"d%dimage%d.png", imageSection, i]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = kScrollObjHeight; rect.size.width = kScrollObjWidth; imageView.frame = rect; imageView.tag = i; // tag our images for later use when we place them in serial fashion [scrollView addSubview:imageView]; [imageView release]; } This code is from Apple example and it works fine. But if the variable 'i' is bigger than 10, 'UIImage *image' is empty. The imageName seems to correct. But I don't know why it does not load image. Does anybody sees the problem?? And one more thing. If I do like that, does iOS controls memory automatically? I mean it's kind of wasting memory if all (more than 10) images are loaded on memory even they are not displayed. I've heard that iOS loads images only displayed on screen and free images those are not displayed. Is that right? Thanks for reading.

  • C++, using one byte to store two variables

    - by 2di
    Hi All I am working on representation of the chess board, and I am planning to store it in 32 bytes array, where each byte will be used to store two pieces. (That way only 4 bits are needed per piece) Doing it in that way, results in a overhead for accessing particular index of the board. Do you think that, this code can be optimised or completely different method of accessing indexes can be used? c++ char getPosition(unsigned char* c, int index){ //moving pointer c+=(index>>1); //odd number if (index & 1){ //taking right part return *c & 0xF; }else { //taking left part return *c>>4; } } void setValue(unsigned char* board, char value, int index){ //moving pointer board+=(index>>1); //odd number if (index & 1){ //replace right part //save left value only 4 bits *board = (*board & 0xF0) + value; }else { //replacing left part *board = (*board & 0xF) + (value<<4); } } int main() { char* c = (char*)malloc(32); for (int i = 0; i < 64 ; i++){ setValue((unsigned char*)c, i % 8,i); } for (int i = 0; i < 64 ; i++){ cout<<(int)getPosition((unsigned char*)c, i)<<" "; if (((i+1) % 8 == 0) && (i > 0)){ cout<<endl; } } return 0; } I am equally interested in your opinions regarding chess representations, and optimisation of the method above, as a stand alone problem. Thanks a lot

  • Query on the scope of local variables in C

    - by darkie15
    All, Consider the following code: void func(void) { int a; printf ("%d", a); } int main(int argc, char **argv) { int a = 3; func(); printf("%d", a); } According to my understanding, the output should be: <junk value><3> Can anyone please confirm my understanding? My basic query is, does the compiler refer to the outer scope for a variable that has been declared but not defined? Regards, darkie

  • [Visual C++]Forcing memory alignment of variables/data-structures

    - by John
    I'm looking at using SSE and I gather aligning data on 16byte boundaries is recommended. There are two cases to consider: float data[4]; struct myystruct { float x,y,z,w; }; I'm not sure the first case can be done explicitly, though there's perhaps a compiler option I could use? In the second case I remember being able to control packing in old versions of GCC several years back, is this still possible?

  • Table Variables in SSIS

    - by aceinthehole
    In one SQL Task can I create a table variable DELCARE @TableVar TABLE (...) Then in another SQL Task or DataSource destination and select or insert into the table variable? The other option I have considered is using a Temp Table. CREATE TABLE #TempTable (...) I would prefer to use Table Variable so that it remains in memory. But can use temp table if it is not possible to use table variable. Also I cannot use the record set destination as I need to preform straight SQL tasks on it later on.
