  • AddHandler not working?

    - by EdenMachine
    I can't figure out why my addhandler is not firing? In the Sub "CreateTagStyle" thd AddHandler is to firing when the LinkButton is clicked Is there some reason that addhandlers can't be adding at certain points of the page lifecycle? <%@ Page Title=""

  • Optimized Image Loading in a UIScrollView

    - by Michael Gaylord
    I have a UIScrollView that has a set of images loaded side-by-side inside it. You can see an example of my app here: http://www.42restaurants.com. My problem comes in with memory usage. I want to lazy load the images as they are about to appear on the screen and unload images that aren't on screen. As you can see in the code I work out at a minimum which image I need to load and then assign the loading portion to an NSOperation and place it on an NSOperationQueue. Everything works great apart from a jerky scrolling experience. I don't know if anyone has any ideas as to how I can make this even more optimized, so that the loading time of each image is minimized or so that the scrolling is less jerky. - (void)scrollViewDidScroll:(UIScrollView *)scrollView{ [self manageThumbs]; } - (void) manageThumbs{ int centerIndex = [self centerThumbIndex]; if(lastCenterIndex == centerIndex){ return; } if(centerIndex >= totalThumbs){ return; } NSRange unloadRange; NSRange loadRange; int totalChange = lastCenterIndex - centerIndex; if(totalChange > 0){ //scrolling backwards loadRange.length = fabsf(totalChange); loadRange.location = centerIndex - 5; unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex + 6; }else if(totalChange < 0){ //scrolling forwards unloadRange.length = fabsf(totalChange); unloadRange.location = centerIndex - 6; loadRange.length = fabsf(totalChange); loadRange.location = centerIndex + 5; } [self unloadImages:unloadRange]; [self loadImages:loadRange]; lastCenterIndex = centerIndex; return; } - (void) unloadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(thumbView.loaded){ UnloadImageOperation *unloadOperation = [[UnloadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:unloadOperation]; [unloadOperation release]; } } } } - (void) loadImages:(NSRange)range{ UIScrollView *scrollView = (UIScrollView *)[[self.view subviews] objectAtIndex:0]; for(int i = 0; i < range.length && range.location + i < [scrollView.subviews count]; i++){ UIView *subview = [scrollView.subviews objectAtIndex:(range.location + i)]; if(subview != nil && [subview isKindOfClass:[ThumbnailView class]]){ ThumbnailView *thumbView = (ThumbnailView *)subview; if(!thumbView.loaded){ LoadImageOperation *loadOperation = [[LoadImageOperation alloc] initWithOperableImage:thumbView]; [queue addOperation:loadOperation]; [loadOperation release]; } } } } EDIT: Thanks for the really great responses. Here is my NSOperation code and ThumbnailView code. I tried a couple of things over the weekend but I only managed to improve performance by suspending the operation queue during scrolling and resuming it when scrolling is finished. Here are my code snippets: //In the init method queue = [[NSOperationQueue alloc] init]; [queue setMaxConcurrentOperationCount:4]; //In the thumbnail view the loadImage and unloadImage methods - (void) loadImage{ if(!loaded){ NSString *filename = [NSString stringWithFormat:@"%03d-cover-front", recipe.identifier, recipe.identifier]; NSString *directory = [NSString stringWithFormat:@"RestaurantContent/%03d", recipe.identifier]; NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"png" inDirectory:directory]; UIImage *image = [UIImage imageWithContentsOfFile:path]; imageView = [[ImageView alloc] initWithImage:image andFrame:CGRectMake(0.0f, 0.0f, 176.0f, 262.0f)]; [self addSubview:imageView]; [self sendSubviewToBack:imageView]; [imageView release]; loaded = YES; } } - (void) unloadImage{ if(loaded){ [imageView removeFromSuperview]; imageView = nil; loaded = NO; } } Then my load and unload operations: - (id) initWithOperableImage:(id<OperableImage>) anOperableImage{ self = [super init]; if (self != nil) { self.image = anOperableImage; } return self; } //This is the main method in the load image operation - (void)main { [image loadImage]; } //This is the main method in the unload image operation - (void)main { [image unloadImage]; }

  • ExtJS: Ext.data.DataReader: #realize was called with invalid remote-data

    - by TomH
    I'm receiving a "Ext.data.DataReader: #realize was called with invalid remote-data" error when I create a new record via a POST request. Although similar to the discussion at this SO conversation, my situation is slightly different: My server returns the pk of the new record and additional information that is to be associated with the new record in the grid. My server returns the following: {'success':true,'message':'Created Quote','data': [{'id':'610'}, {'quoteNumber':'1'}]} Where id is the PK for the record in the mysql database. quoteNumber is a db generated value that needs to be added to the created record. Other relevant bits: var quoteRecord = Ext.data.Record.create([{name:'id', type:'int'},{name:'quoteNumber', type:'int'},{name:'slideID'}, {name:'speaker'},{name:'quote'}, {name:'metadataID'}, {name:'priorityID'}]); var quoteWriter = new Ext.data.JsonWriter({ writeAllFields:false, encode:true }); var quoteReader = new Ext.data.JsonReader({id:'id', root:'data',totalProperty: 'totalitems', successProperty: 'success',messageProperty: 'message',idProperty:'id'}, quoteRecord); I'm stumped. Anyone?? thanks tom

  • C# - Pass by value & Pass by Reference

    - by Lijo
    Hi Team, Could you please explain the following behavior of C# Class. I expect the classResult as "Class Lijo"; but actual value is “Changed”. We’re making a copy of the reference. Though the copy is pointing to the same address, the method receiving the argument cannot change original. Still why the value gets changed ? public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Person p = new Person(); p.Name = "Class Lijo"; Utilityclass.TestMethod(p); string classResult = p.Name; Response.Write(classResult); } } public class Utilityclass { public static void TestMethod(Person k) { k.Name = "Changed"; } } public class Person { private string name; public string Name { get { return name; } set { name = value; } } } Thanks Lijo

  • Override Javascript Function Based on Passed Parameters

    - by George
    Is it possible to override a function based on the number of parameters that you are passing into it? For instance: function abc(name) { document.write ('My name is' + name); } function abc(name,friend) { document.write ('My name is' + name + 'and my best friend\'s name is' + friend); } So in the HTML if I just called abc(george) it would use the first version of the function, but if I called abc(george,john) it would use the second version. There may be other ways to accomplish the example I used, but I'm just wondering if the concept is sound in javascript.

  • Email Validation from WTForm using Flask

    - by lost9123193
    I'm following a Flask tutorial from http://code.tutsplus.com/tutorials/intro-to-flask-adding-a-contact-page--net-28982 and am currently stuck on the validation step: The old version had the following: from flask.ext.wtf import Form, TextField, TextAreaField, SubmitField, validators, ValidationError class ContactForm(Form): name = TextField("Name", [validators.Required("Please enter your name.")]) email = TextField("Email", [validators.Required("Please enter your email address."), validators.Email("Please enter your email address.")]) submit = SubmitField("Send") Reading the comments I updated it to this: (replaced validators.Required with InputRequired) (same fields) class ContactForm(Form): name = TextField("Name", validators=[InputRequired('Please enter your name.')]) email = EmailField("Email", validators=[InputRequired("Please enter your email address.")]), validators.Email("Please enter your email address.")]) submit = SubmitField("Send") My only issue is I don't know what to do with the validators.Email. The error message I get is: NameError: name 'validators' is not defined I've looked over the documentation, perhaps I didn't delve deep enough but I can't seem to find an example for email validation.

  • Spring MVC annotation config problem

    - by Seth
    I'm trying to improve my spring mvc configuration so as to not require a new config file for every servlet I add, but I'm running into problems. I've tried using this tutorial as a starting point, but I'm running into an issue that I can't figure out. The problem is that when I do a GET to my servlet, I get back a 404 error.

  • How can I show figures separately in matplotlib?

    - by Federico Ramponi
    Say that I have two figures in matplotlib, with one plot per figure: import matplotlib.pyplot as plt f1 = plt.figure() plt.plot(range(0,10)) f2 = plt.figure() plt.plot(range(10,20)) Then I show both in one shot plt.show() Is there a way to show them separately, i.e. to show just f1? Or better: how can I manage the figures separately like in the following 'wishful' code (that doesn't work): f1 = plt.figure() f1.plot(range(0,10)) f1.show()

  • Encoding issue - 2nd band of ISO-8859-1 values do not get encoded?

    - by bstack
    Hello, I want to send the pound sign character i.e. '£' encoded as ISO-8859-1 across the wire. I perform this by doing the following: var _encoding = Encoding.GetEncoding("iso-8859-1"); var _requestContent = _encoding.GetBytes(requestContent); var _request = (HttpWebRequest)WebRequest.Create(target); _request.Headers[HttpRequestHeader.ContentEncoding] = _encoding.WebName; _request.Method = "POST"; _request.ContentType = "application/x-www-form-urlencoded; charset=iso-8859-1"; _request.ContentLength = _requestContent.Length; _requestStream = _request.GetRequestStream(); _requestStream.Write(_requestContent, 0, _requestContent.Length); _requestStream.Flush(); _requestStream.Close(); When I put a breakpoint at the target, I expect to receive the following: '%a3', however I receive '%u00a3' instead. ISO-8859-1 is divided into 2 groups of characters: (ref: http://en.wikipedia.org/wiki/ISO_8859-1) The lower range 20 to 7E - is where all characters seem to be encoded correctly The higher range A0 to FF - is where all characters seem to encode to their Unicode equivalent value As '£' is in higher range A0 to FF, it gets encoded to %u00a3. In fact when I use the first few characters of the higher range A0 to FF i.e. '¡¢£¤¥¦§¨©ª«¬®', I get '%u00a1%u00a2%u00a3%u00a4%u00a5%u00a6%u00a7%u00a8%u00a9%u00aa%u00ab%u00ac%u00ae'. This behaviour is consistent. The question I have is why do characters in the higher range A0 to FF get encoded to their unicode value - and not to their equivalent ISO-8859-1 value? Help would be greatly appreciated... Billy

  • integer Max value constants in SQL Server T-SQL?

    Are there any constants in T-SQL like there are in some other languages that provide the max and min values ranges of data types such as int? I have a code table where each row has an upper and lower range column, and I need an entry that represents a range where the upper range is the maximum value an int can hold(sort of like a hackish infinity). I would prefer not to hard code it and instead use something like SET UpperRange = int.Max

  • jqgrid ASP.NET MVC -- getting data right for the grid.

    - by SamM09
    Here is my dilemma, I have not been able to manipulate my data to a form fitting to jqgrid standards. This is my first time using the jqgrid and I've spent a lot of time reading up on it. My js code is as follows: jQuery("#list").jqGrid({ url: '/Home/ListContacts/', dataType: "json", contentType: "application/json; charset=utf-8", mtype: 'POST', colNames: ['First Name', 'MI', 'Last Name'], colModel: [ { name: 'First Name', index: 'FName', width: 40, align: 'left' }, { name: 'MI', index: 'MInitial', width: 40, align: 'left' }, { name: 'Last Name', index: 'LName', width: 400, align: 'left'}], pager: jQuery('#pager'), rowNum: 10, rowList: [5, 10, 20, 50], sortname: 'Id', sortorder: "desc", repeatitems: false, viewrecords: true, imgpath: '/scripts/themes/basic/images', caption: 'My first grid' }); }); what im getting from the database: [["4","Jenna","Mccarthy"],["56","wer","weoiru"]] Now correct me if I am wrong, but the index: in my colModel refers to the column names in my database right? Could someone point to a reference that is straight forward or just start me off with this I would be most grateful.

  • adding nodes to a binary search tree randomly deletes nodes

    - by SDLFunTimes
    Hi, stack. I've got a binary tree of type TYPE (TYPE is a typedef of data*) that can add and remove elements. However for some reason certain values added will overwrite previous elements. Here's my code with examples of it inserting without overwriting elements and it not overwriting elements. the data I'm storing: struct data { int number; char *name; }; typedef struct data data; # ifndef TYPE # define TYPE data* # define TYPE_SIZE sizeof(data*) # endif The tree struct: struct Node { TYPE val; struct Node *left; struct Node *rght; }; struct BSTree { struct Node *root; int cnt; }; The comparator for the data. int compare(TYPE left, TYPE right) { int left_len; int right_len; int shortest_string; /* find longest string */ left_len = strlen(left->name); right_len = strlen(right->name); if(right_len < left_len) { shortest_string = right_len; } else { shortest_string = left_len; } /* compare strings */ if(strncmp(left->name, right->name, shortest_string) > 1) { return 1; } else if(strncmp(left->name, right->name, shortest_string) < 1) { return -1; } else { /* strings are equal */ if(left->number > right->number) { return 1; } else if(left->number < right->number) { return -1; } else { return 0; } } } And the add method struct Node* _addNode(struct Node* cur, TYPE val) { if(cur == NULL) { /* no root has been made */ cur = _createNode(val); return cur; } else { int cmp; cmp = compare(cur->val, val); if(cmp == -1) { /* go left */ if(cur->left == NULL) { printf("adding on left node val %d\n", cur->val->number); cur->left = _createNode(val); } else { return _addNode(cur->left, val); } } else if(cmp >= 0) { /* go right */ if(cur->rght == NULL) { printf("adding on right node val %d\n", cur->val->number); cur->rght = _createNode(val); } else { return _addNode(cur->rght, val); } } return cur; } } void addBSTree(struct BSTree *tree, TYPE val) { tree->root = _addNode(tree->root, val); tree->cnt++; } The function to print the tree: void printTree(struct Node *cur) { if (cur == 0) { printf("\n"); } else { printf("("); printTree(cur->left); printf(" %s, %d ", cur->val->name, cur->val->number); printTree(cur->rght); printf(")\n"); } } Here's an example of some data that will overwrite previous elements: struct BSTree myTree; struct data myData1, myData2, myData3; myData1.number = 5; myData1.name = "rooty"; myData2.number = 1; myData2.name = "lefty"; myData3.number = 10; myData3.name = "righty"; initBSTree(&myTree); addBSTree(&myTree, &myData1); addBSTree(&myTree, &myData2); addBSTree(&myTree, &myData3); printTree(myTree.root); Which will print: (( righty, 10 ) lefty, 1 ) Finally here's some test data that will go in the exact same spot as the previous data, but this time no data is overwritten: struct BSTree myTree; struct data myData1, myData2, myData3; myData1.number = 5; myData1.name = "i"; myData2.number = 5; myData2.name = "h"; myData3.number = 5; myData3.name = "j"; initBSTree(&myTree); addBSTree(&myTree, &myData1); addBSTree(&myTree, &myData2); addBSTree(&myTree, &myData3); printTree(myTree.root); Which prints: (( j, 5 ) i, 5 ( h, 5 ) ) Does anyone know what might be going wrong? Sorry if this post was kind of long.

  • What is the `name` keyword in JavaScript?

    - by Joey Adams
    When I typed this apparently innocent snippet of code: values.name gedit highlighted name as a keyword. However, name is not listed by the pages linked to by an answer to a question about reserved keywords. I also did a couple trivial tests in SpiderMonkey, but name seemed to act like an ordinary identifier. A Google search didn't tell me much either. However, I did find a page listing name in "Other JavaScript Keywords". My guess is that name is a function or a member of some DOM element and does not intrude on the namespace. Is name really a keyword in JavaScript? If so, what does it do?
