  • Align child element to bottom with CSS

    - by alex
    I have a form input, and the label spans multiple lines, and I want the corresponding checkbox to appear at the bottom (last line of the label element). Here is what I was playing with CSS .standard-form { width: 500px; border: 1px solid red; } .standard-form .input-row { overflow: hidden; margin-bottom: 0.8em; } .standard-form label { width: 25%; float: left; } .standard-form .input-container { width: 70%; float: right; } .standard-form .checkbox .input-container { display: table-cell; height: 100%; vertical-align: text-bottom; } HTML <form class="standard-form"> <div class="input-row checkbox" id="permission"> <label for="input-permission"> Do I hereby grant you permission to do whatever tasks are neccessary to achieve an ideal outcome? </label> <div class="input-container"> <input type="checkbox" id="input-permission" name="permission" value="true" /> </div> </div> </form> It is also online at JSbin. Is there any way to do this? I notice that div.input-container isn't expanding, which is the old multi column problem with CSS. I thought I could get this going with display: table-cell and vertical-align: bottom but I haven't been able to do it yet. I don't mind that IE6/7 won't render it correctly.

  • JQuery dynamic .load - works for 1 and not for the other??

    - by Alvin
    UPDATE: Site is online http://qwickqual.com/memorial/create/ under "Memoria Media" - Click on "Our Videos" and it loads the list of categories click on any sub category and it goes through the process below ---------------- end edit ---------------------------------- UPDATED DESCRIPTION OF ERROR: All code is based on <li> objects being linked If I click on an <li> from the Initial page load to load: section 1: I can click on an <li> to load sub-categories section 2: I then click on an <li>, the query is made server returns section 3, section is not loaded to screen / and callback function is skipped over perhaps someone has run into a similar issue before?? ---------------- end edit ---------------------------------- I've also added comments to the code I have a jquery function that is setup to load categorized lists of thumbnails. So far the function is in use in 3 location. Each of them generates HTML using the same template under django. The function works perfectly in 2 of the 3 locations, and I"m plain stumped as to why the 3rd won't work. Below is the complete set of relevant javascript, the page load HTML for the relevant section. And 2 examples of HTML that is loaded through the script, 1 of them works, 1 of them doesn't and both are loaded into the same page load HTML Any ideas what I'm missing here? Or information I need to add to help debug? Currently posting this to a live server to interact with, been local only till now... Error: Script works properly through all levels of title="our_photos" Script loads 1st level of title="our_videos" Script will not load sub-category of title="our_videos" Example: From HTML below: Click on Script will query the server properly: GET http://localhost%3A8000/memorial/media%5Ftype/our%5Fvideos/4/ Script will not load the returned HTML into the #select_media div scopeChain: [Call, Call multi=false uri=/memorial/media_type/our_videos/, Window # 0=Call 1=Call 2=window] relative vars: label = "our_videos" wrapper = "media" uri = "/memorial/media_type/our_videos/" multi = false Javascript <script type="text/javascript"> // this piece is where I'm having trouble in the grand scheme of things // label = piece of class tag // wrapper = tag to load everything inside of // uri = base of the page to load // multi = not relevant for this piece but needed to pass on to next function function img_thumb_loader(label, wrapper, uri, multi) { if(!(wrapper)) { wrapper = label } $('.'+label+'_category').click(function () { // show the loading animation $('div#'+wrapper+'_load').show();

  • Detect if any USB drive is detected or not using WinForm Application

    - by Pavan Kumar
    I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.

  • Very simple python functions takes spends long time in function and not subfunctions

    - by John Salvatier
    I have spent many hours trying to figure what is going on here. The function 'grad_logp' in the code below is called many times in my program, and cProfile and runsnakerun the visualize the results reveals that the function grad_logp spends about .00004s 'locally' every call not in any functions it calls and the function 'n' spends about .00006s locally every call. Together these two times make up about 30% of program time that I care about. It doesn't seem like this is function overhead as other python functions spend far less time 'locally' and merging 'grad_logp' and 'n' does not make my program faster, but the operations that these two functions do seem rather trivial. Does anyone have any suggestions on what might be happening? Have I done something obviously inefficient? Am I misunderstanding how cProfile works? def grad_logp(self, variable, calculation_set ): p = params(self.p,self.parents) return self.n(variable, self.p) def n (self, variable, p ): gradient = self.gg(variable, p) return np.reshape(gradient, np.shape(variable.value)) def gg(self, variable, p): if variable is self: gradient = self._grad_logps['x']( x = self.value, **p) else: gradient = __builtin__.sum([self._pgradient(variable, parameter, value, p) for parameter, value in self.parents.iteritems()]) return gradient

  • Catching the return of main function before it deallocates resources

    - by EpsilonVector
    I'm trying to implement user threads in Linux kernel 2.4, and I ran into something problematic and unexpected. Background: a thread basically executes a single function and dies, except that when I call thread_create for the first time it must turn main() into a thread as well (by default it is not a thread until the first call, which is also when all the related data structures are allocated). Since a thread executes a function and dies, we don't need to "return" anywhere with it, but we do need to save the return value to be reclaimed later with thread_join, so the hack I came up with was: when I allocate the thread stack I place a return address that points to a thread_return_handler function, which deallocates the thread, makes it a zombie, and saves its return value for later. This works for "just run a function and die" threads, but is very problematic with the main thread. Since it actually is the main function, if it returns before the other threads finish the normal return mechanism kicks in, and deallocates all the shared resources, thus screwing up all the running threads. I need to keep it from doing that. Any ideas on how it can be done?

  • xslt check for alpha numeric character

  • Magento - use an alternate "price.phtml" (in addition to the existing one)

    - by sdek
    I am looking for a way to have an alternate template/catalog/product/price.phml used in one specific location, and to continue using the existing price.phtml file in all other locations. To explain further, I need to display the regular price, and then another special price right below it - but only on the product page (for the main product being displayed). This special price is not a price that can be calculated by the catalog price rules, so I wrote my own module to do the calculation. So, everywhere that I am displaying prices I want to display with the regular ol' template/catalog/product/price.phtml file... but for the product page (the main product - not the related, upsells, etc) I want to use my own custom template/catalog/product/price-custom.phtml template file. Can anybody help? Normally I just look in the layout xml files (for example catalog.xml) to find these types of things, but price.phtml is kinda special - it isn't that simple. And for the life of me I can't figure out if there is an easy way to swap it out conditionally on the page being viewed. I am aware that I can just update price.phtml to always print out this extra price, and then use css to hide the price everywhere, but I would rather not do that if possible. (Also you may want to know that I only have simple products.)

  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • Is Safari on iOS 6 caching $.ajax results?

    - by user1684978
    Since the upgrade to iOS 6, we are seeing Safari's web view take the liberty of caching $.ajax calls. This is in the context of a PhoneGap application so it is using the Safari WebView. Our $.ajax calls are POST methods and we have cache set to false {cache:false}, but still this is happening. We tried manually adding a timestamp to the headers but it did not help. We did more research and found that Safari is only returning cached results for web services that have a function signature that is static and does not change from call to call. For instance, imagine a function called something like: getNewRecordID(intRecordType) This function receives the same input parameters over and over again, but the data it returns should be different every time. Must be in Apple's haste to make iOS 6 zip along impressively they got too happy with the cache settings. Has anyone else seen this behavior on iOS 6? If so, what exactly is causing it? The workaround that we found was to modify the function signature to be something like this: getNewRecordID(intRecordType, strTimestamp) and then always pass in a timestamp parameter as well, and just discard that value on the server side. This works around the issue. I hope this helps some other poor soul who spends 15 hours on this issue like I did!

  • whats a sure shot way to make sure objects appear correctly positioned on stage

    - by dubbeat
    Hi, I've being having a lot of trouble recently getting objects (UIComponents containing movieclips) to appear correctly in the right positions. For example, my current dilema is I have a container that is 3 layers deep. outer layer inner layer display layer This hiearachy was built in CS4 as a movieclip. In the display layer in CS4 I figured out where I want to place 16 different "box" movieclips. I dont want to create these boxes maunually at design time, instead I want to add them at run time. So I know what container I want to add my boxes to. I know what positions they "would" be at in CS4 environment. Whats the best way to add them in the correct locations with code? The "box" I'm trying to add in a movieclip held inside of a UIComponent. Is there a "rule of thumb" to do this type of thing? I'm sure I'm going to encounter this problem again and again and I'd like to just blow the problem out of the water once and for all with the "right way" to do this.

  • Array of Arrays - writing to File problem

    - by iFloh
    Hi, and again my array of arrays ... I try to improve my app performance by buffering arrays on file for later reuse. I have an NSMutableArray that contains about 30 NSMutableArrays with NSNumber, NSDate and NSString Objects. I try to write the file using this call: bool result = [myArray writeToFile:[fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]] atomically:NO]; = result = FALSE. The Path method is: + (NSString *) getFullPath:(NSString *)forFileName { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:forFileName]; } and the aDate call returns a shortDateString with ddMMyy. The NSLog NSLog(@"%@", [fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]]); on the path generation returns: /Users/me/Library/Application Support/iPhone Simulator/User/Applications/86729620-EC1D-4C10-A799-0C638BB27933/Documents/iEts010510.arr FURTHER: It must have something to do with the Array of Arrays, since I also write 3 further simple arrays (containing NSStrings) that all succeed. The Array of Arrays gets generated using the addObject method Any ideas what could cause the trouble?

  • ZendFramework Headscript Helper - Make scripts unique

    - by tokam
    How can I ensure that the headScript and headStyle helper include css files only once when added? The reason I am asking is that I would like to display some contents in a lightbox and all Flashmassages.E.g. notifications like profile successfully edited. To display flashmessages in the lightbox i would like to check at the top of my layout script if they are set, in case they are i would like to attach the required javascript library using the headScript helper. The problem is that I have no control about the scripts which were already added at this point. Maybe at a page where the library is needed for an other use case, it has already been added with addScript. How can I ensure all scripts are added only once to my helper? I already checked that these helpers extend Zend_View_Helper_Placeholder_Container_Standalone which uses an ArrayObject internally to hold the data and provides getters & setter to the array object. Maybe a solution here would be to check each time when adding a script file if it already exists using the ArrayObject?

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to use Facebook connect in my application, but its not working as I desire. When I am trying to use the API Key and the API SecretKey of my application which I have registered with the facebook its not working. I have downloaded the code for the facebook. In the SessionViewController.m file when I pass my key values its not working. What I am trying to achieve is, when the app launches the first page is the Facebook Login Page. The user enters his username and password and then the next view should display. But nothing is happening, even the label doesn't display the username. Heres the code which I am using - (void)request:(FBRequest*)request didLoad:(id)result { NSArray* users = result; NSDictionary* user = [users objectAtIndex:0]; NSString* name = [user objectForKey:@"name"]; _label.text = [NSString stringWithFormat:@"Logged in as %@",name]; NSLog(@"Username is :- %@",name); FrontController *main = [[FrontController alloc] init]; [self.view addSubview:main.view]; [main release]; } I am not able to figure out what is wrong with this code. When I try with some other key values such as the key for connect application its working fine. Can anyone help me with this... Thanx in advance...

  • RIA Service - without database?

    - by Heko
    Helo! I need to write a RIA service to call Java webservices from Silverlight 3.0 app. I'm testing how stuff works and in my Web app I have a MyData class which has 2 properties (int ID, string Text): namespace SilverlightApplication1.Web { public class MyData { [Key] public int ID { get; set; } public string Text { get; set; } } } Then I wrote simple DomainService: [EnableClientAccess()] public class MyService : DomainService { public IQueryable<MyData> GetMyData(string Url) { // here I will call my WebService List<MyData> result = new List<MyData>(); result.Add(new MyData { ID = 1, Text = Url }); return result.AsQueryable(); } } } How can I get data into my SL app? Now I have this: namespace SilverlightApplication1 { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MyContext context = new MyContext(); } } } I called and load but nothink worsk (exceptions, or nulls)... I had Invoke annotation but MyData is not TEntity and I can't use Strings or other simple types as well... :/ I'm reading and reading posts and nothing works like it should.. Any help would be really appreciated. Thank you!

  • Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

    - by Andrew Arrow
    Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

  • callback on a variable which is inside a .each() loop

    - by Stoic
    I have this function, which is doing an asynchronous call to FB.api method. Now, i am looping over some data and capturing result of the above method call successfully. However, I am using a .each loop and I really can not figure out how to place my callback in this method, so that the outer method is only executed once. Here are the functions I am using: ask_for_perms($(this).val(),function(result) { $('#some-div').html('<a onclick = "get_perms(result);" >get perms</a>'); }); function ask_for_perms(perms_requested,cb) { var request = []; $.each(perms_requested,function(i,permission) { FB.api({ method: 'users.hasAppPermission', ext_perm: permission }, function(response) { if (response == 0) request.push(permission); request.join(','); cb(request); // cb is called many times here. }); }); } I am trying to return the request string from ask_for_perms function. Can anyone suggest me on where to place a proper callback to ask_for_perms. Right now, however, it works for me, but the callback is being called many times since it is inside a for loop. referencing: returning a variable from the callback of a function

  • Subquery with multiple results combined into a single field?

    - by Todd
    Assume I have these tables, from which i need to display search results in a browser: Table: Containers id | name 1 Big Box 2 Grocery Bag 3 Envelope 4 Zip Lock Table: Sale id | date | containerid 1 20100101 1 2 20100102 2 3 20091201 3 4 20091115 4 Table: Items id | name | saleid 1 Barbie Doll 1 2 Coin 3 3 Pop-Top 4 4 Barbie Doll 2 5 Coin 4 I need output that looks like this: itemid itemname saleids saledates containerids containertypes 1 Barbie Doll 1,2 20100101,20100102 1,2 Big Box, Grocery Bag 2 Coin 3,4 20091201,20091115 3,4 Envelope, Zip Lock 3 Pop-Top 4 20091115 4 Zip Lock The important part is that each item type only gets one record/row in the return on the screen. I accomplished this in the past by returning multiple rows of the same item and using a scripting language to limit the output. However, this makes the ui overly complicated and loopy. So, I'm hoping I can get the database to spit out only as many records as there are rows to display. This example may be a bit extreme because of the 2 joins needed to get to the container from the item (through the sale table). I'd be happy for just an example query that outputs this: itemid itemname saleids saledates 1 Barbie Doll 1,2 20100101,20100102 2 Coin 3,4 20091201,20091115 3 Pop-Top 4 20091115 I can only return a single result in a subquery, so I'm not sure how to do this.

  • Performance issue finding weekdays over a given period

    - by Oysio
    I have some methods that return the number of weekdays between two given dates. Since calling these methods become very expensive to call when the two dates lie years apart, I'm wondering how these methods could be refactored in a more efficient way. The returned result is correct but I feel that the iphone processor is struggling to keep up and consequently freezes up the application when I would call these methods over a period of say 10years. Any suggestions ? //daysList contains all weekdays that need to be found between the two dates -(NSInteger) numberOfWeekdaysFromDaysList:(NSMutableArray*) daysList startingFromDate:(NSDate*)startDate toDate:(NSDate*)endDate { NSInteger retNumdays = 0; for (Day *dayObject in [daysList objectEnumerator]) { if ([dayObject isChecked]) { retNumdays += [self numberOfWeekday:[dayObject weekdayNr] startingFromDate:startDate toDate:endDate]; } } return retNumdays; } -(NSInteger) numberOfWeekday:(NSInteger)day startingFromDate:(NSDate*)startDate toDate:(NSDate*)endDate { NSInteger numWeekdays = 0; NSDate *nextDate = startDate; NSComparisonResult result = [endDate compare:nextDate]; //Do while nextDate is in the past while (result == NSOrderedDescending || result == NSOrderedSame) { if ([NSDate weekdayFromDate:nextDate] == day) { numWeekdays++; } nextDate = [nextDate dateByAddingDays:1]; result = [endDate compare:nextDate]; } return numWeekdays; }

  • Data confusion - Selecting data in one DataGridView based on selection in another

    - by Logan Young
    This probably isn't the best way to do what I want, but I can't think of anything else to try... NB: I'm using Visual Basic.NET My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid. When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid. So, basically, I want to dynamically display data in one grid based on user selection in another grid. My code looks like this so far... Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick Try FlagsGrid.Visible = True ''// MsgBox(RulesGrid.CurrentCell.Value.ToString()) Dim sql As String = "SELECT * FROM ctblMKA_Status_Flags " + _ "WHERE intStatusID = '" & RulesGrid.CurrentCell.Value & "'" DSFlags = GetDS(sql) DSFlags.DataSetName = "FlagsDataSet" FlagsGrid.DataSource = DSFlags ProgressBar.Visible = False Catch ex As Exception MsgBox(ex.ToString) End Try End Sub I feel like I'm missing something here... Any ideas anyone?

  • Creating an adjacency List for DFS

    - by user200081
    I'm having trouble creating a Depth First Search for my program. So far I have a class of edges and a class of regions. I want to store all the connected edges inside one node of my region. I can tell if something is connected by the getKey() function I have already implemented. If two edges have the same key, then they are connected. For the next region, I want to store another set of connected edges inside that region, etc etc. However, I am not fully understanding DFS and I'm having some trouble implementing it. I'm not sure when/where to call DFS again. Any help would be appreciated! class edge { private: int source, destination, length; int key; edge *next; public: getKey(){ return key; } } class region { edge *data; edge *next; region() { data = new edge(); next = NULL; } }; void runDFS(int i, edge **edge, int a) { region *head = new region(); aa[i]->visited == true;//mark the first vertex as true for(int v = 0; v < a; v++) { if(tem->edge[i].getKey() == tem->edge[v].getKey()) //if the edges of the vertex have the same root { if(head->data == NULL) { head->data = aa[i]; head->data->next == NULL; } //create an edge if(head->data) { head->data->next = aa[i]; head->data->next->next == NULL; }//if there is already a node connected to ti } if(aa[v]->visited == false) runDFS(v, edge, a); //call the DFS again } //for loop }

  • jQuery ajax only works first time

    - by Michael Itzoe
    I have a table of data that on a button click certain values are saved to the database, while other values are retrieved. I need the process to be continuous, but I can only get it to work the first time. At first I was using .ajax() and .replaceWith() to rewrite the entire table, but because this overwrites the DOM it was losing events associated with the table. I cannot use .live() because I'm using stopPropagation() and .live() doesn't support it due to event bubbling. I was able to essentially re-bind the click event onto the table within the .ajax() callback, but a second call to the button click event did nothing. I changed the code to use .get() for the ajax and .html() to put the results in the table (the server-side code now returns the complete table sans the <table> tags). I no longer have to rebind the click event to the table, but subsequent clicks to the button still do nothing. Finally, I changed it to .load(), but with the same (non-) results. By "do nothing" I mean while the ajax call is returning the new HTML as expected, it's not being applied to the table. I'm sure it has something to do with altering the DOM, but I thought since I'm only overwriting the table contents and not the table object itself, it should work. Obviously I'm missing something; what is it? Edit: HTML: <table id="table1" class="mytable"> <tr> <td><span id="item1" class="myitem"></span> <td><span id="item2" class="myitem"></span> </tr> </table> <input id="Button1" type="button" value="Submit" /> jQuery: $( "Button1" ).click( function() { $( "table1" ).load( "data.aspx", function( data ) { //... } ); } );

  • Debugging scripts loaded with GroovyShell (in eclipse)

    - by MSh
    I am working with eclipse and groovy plug in. I am building a test harness to debug and test groovy scripts. The scripts are really simple but long, most of them just if/else/return. I figured out that I can call them using GroovyShell and Bindings to pass in the values. The problem is that, while I can call the script and get the results just fine, I CAN NOT step in there with the debugger. Breakpoints in those scripts are not active. Is there a way to debug the scripts? Maybe I should use something other than GroovyShell? I really don't want to modify the scripts by wrapping them into functions, and then calling those functions from my test classes. That's how I am using Binding and GroovyShell: def binding = new Binding(); binding.lineList = [list1]; binding.count = 5; def shell = new GroovyShell(binding); def result = shell.evaluate(new File("src/Rules/checkLimit.groovy"));
