  • Can I user a layout on the android to render just part of an image at a time?

    - by gamernb
    I have an image file that has all the character sprites that I will be using in a game, and I want to make a layout that will allow the user to cycle through each image to be able to pick which one they want. So, I have one large image, and I need to render just a small (32 x 32) section of it at a time. Is that possible with the layouts or will I have to use a canvas, and manually do most of this?

  • NSMutableDictionary confused over how to use keys with certain code ?

    - by Jules
    I'm getting data from a database and I need to add the string field value and the record id. However, I need this to work with some existing code... I'm replacing this (see code below) and getting data from my database. NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path]; self.allCategories = dict; [dict release]; But needs to work with these key and value search functions. - (void)resetSearch { NSMutableDictionary *allCategoriesCopy = [self.allCategories mutableDeepCopy]; self.Categories = allCategoriesCopy; [allCategoriesCopy release]; NSMutableArray *keyArray = [[NSMutableArray alloc] init]; [keyArray addObject:UITableViewIndexSearch]; [keyArray addObjectsFromArray:[[self.allCategories allKeys] sortedArrayUsingSelector:@selector(compare:)]]; self.keys = keyArray; [keyArray release]; } . - (void)handleSearchForTerm:(NSString *)searchTerm { NSMutableArray *sectionsToRemove = [[NSMutableArray alloc] init]; [self resetSearch]; for (NSString *key in self.keys) { NSMutableArray *array = [Categories valueForKey:key]; NSMutableArray *toRemove = [[NSMutableArray alloc] init]; for (NSString *name in array) { if ([name rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location == NSNotFound) [toRemove addObject:name]; } if ([array count] == [toRemove count]) [sectionsToRemove addObject:key]; [array removeObjectsInArray:toRemove]; [toRemove release]; } [self.keys removeObjectsInArray:sectionsToRemove]; [sectionsToRemove release]; [table reloadData]; } Keep getting an error from this code... NSDictionary *arrayTmp= [[NSDictionary alloc] init]; ... loop records int cid = sqlite3_column_int(statementTMP, 0); NSString *category = [[NSString alloc] initWithUTF8String:(char *)sqlite3_column_text(statementTMP, 1)]; [arrayTmp setObject:category forKey:[NSString stringWithFormat:@"%i", cid]]; Error caused by line above * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCFString count]: unrecognized selector sent to instance 0x4d4c500' * Call stack at first throw * ... end loop self.allCategories = arrayTmp; [arrayTmp release];

  • Detect session hang and kill it

    - by Jack Juiceson
    Hi all, I have an asp.net page that runs certain algorithm and returns it's output. I was wondering what will happen and how to handle a case where the algorithm due to a bug goes into infinite loop. It will hog the cpu and other sessions will be served very slowly. I would love to have a way to tell IIS, if processing Algo.aspx takes more than 5 seconds, kill it or something like that. Thanks in advance

  • Semantic #region usage

    - by Luca
    What's your opinion about using #region folding using application semantic, instead of folding for "syntax". For example: #region Application Loop #region User Management #region This Kinf of stuffs instead of #region Private Routines #region Public Properties #region ThisRoutine // (Yes, I've seen this also!) In this logic, I'm starting fold even routine bodies. I'm starting to love #region directive (even using #pragma region when using C++!).

  • Allocation of IP Address in Ad hoc systems

    - by Kasturi
    Me and my friends play Age of Empires every weekend and create an Ad-hoc network each time before playing. But each time we all get the SAME IP Address even if a new ad-hoc network is created. Is this something to do with the Game's algorithm or does the laptop remember our previous IP Address. EDIT: What is the algorithm that is used to distribute the IP Addresses? If the algorithm uses random function how come same IP addresses are being allocated.

  • How to automatically include a number of images in the SWF file?

    - by Ponty
    Hi, i'm trying to include a number of images in my SWF file not by loading them but by embedding them in the SWF itself. I found the following instruction to do that: [Embed(source="../graphics/images/ss0.png")] private var SS0:Class; Basically, i want to embed a different number of images each time. Is there a way to do that automatically (let's say inside a for loop) or do i have to type manually this instruction for each image i want to include?

  • Best way to initialise / clear a string variable cocoa

    - by Spider-Paddy
    I have a routine that parses text via a loop. At the end of each record I need to clear my string variables but I read that someString = @"" actually just points to a new string & causes a memory leak. What is the best way to handle this? Should I rather use mutable string vars and use setString:@"" between iterations?

  • How to tell if 2 arrays share the same element.

    - by Ommit
    So this is a simpler form of my problem. Lets say I have 2 arrays. A= {1,2} and B={2,4,6}. If A and B share an element then delete that element from B. I know you can loop through and compare each element in A to each element in B, but there's got to be a better way!

  • MVC 3 Nested EditorFor Templates

    - by Gordon Hickley
    I am working with MVC 3, Razor views and EditorFor templates. I have three simple nested models:- public class BillingMatrixViewModel { public ICollection<BillingRateRowViewModel> BillingRateRows { get; set; } public BillingMatrixViewModel() { BillingRateRows = new Collection<BillingRateRowViewModel>(); } } public class BillingRateRowViewModel { public ICollection<BillingRate> BillingRates { get; set; } public BillingRateRowViewModel() { BillingRates = new Collection<BillingRate>(); } } public class BillingRate { public int Id { get; set; } public int Rate { get; set; } } The BillingMatrixViewModel has a view:- @using System.Collections @using WIP_Data_Migration.Models.ViewModels @model WIP_Data_Migration.Models.ViewModels.BillingMatrixViewModel <table class="matrix" id="matrix"> <tbody> <tr> @Html.EditorFor(model => Model.BillingRateRows, "BillingRateRow") </tr> </tbody> </table> The BillingRateRow has an Editor Template called BillingRateRow:- @using System.Collections @model IEnumerable<WIP_Data_Migration.Models.ViewModels.BillingRateRowViewModel> @foreach (var item in Model) { <tr> <td> @item.BillingRates.First().LabourClass.Name </td> @Html.EditorFor(m => item.BillingRates) </tr> } The BillingRate has an Editor Template:- @model WIP_Data_Migration.Models.BillingRate <td> @Html.TextBoxFor(model => model.Rate, new {style = "width: 20px"}) </td> The markup produced for each input is:- <input name="BillingMatrix.BillingRateRows.item.BillingRates[0].Rate" id="BillingMatrix_BillingRateRows_item_BillingRates_0__Rate" style="width: 20px;" type="text" value="0"/> Notice the name and ID attributes the BillingRate indexes are handled nicely but the BillingRateRows has no index instead '.item.'. From my reasearch this is because the context has been pulled out due to the foreach loop, the loop shouldn't be necessary. I want to achieve:- <input name="BillingMatrix.BillingRateRows[0].BillingRates[0].Rate" id="BillingMatrix_BillingRateRows_0_BillingRates_0__Rate" style="width: 20px;" type="text" value="0"/> If I change the BillingRateRow View to:- @model WIP_Data_Migration.Models.ViewModels.BillingRateRowViewModel <tr> @Html.EditorFor(m => Model.BillingRates) </tr> It will throw an InvalidOperationException, 'model item passed into the dictionary is of type System.Collections.ObjectModel.Collection [BillingRateRowViewModel] but this dictionary required a type of BillingRateRowViewModel. Can anyone shed any light on this?
