  • "out of scope" error when iterating an NSMutableArray

    - by wgpubs
    Why am I getting an "out of scope" error whenever I try to access the "url" variable in this loop? for(NSString *url in self.winnerImageURLs) { [mediaItemString appendFormat:@"{\"type\":\"image\",\"src\":\"%@\",\"href\":\"%@\"},", url, url]; } The class of very item in the "self.winnerImageURLs" NSMutableArray comes back as NSCFString so I'm not sure what the dealio is here. Any ideas on what I'm doing wrong??? Thanks

  • Seeking jQuery-based transition library

    - by justSteve
    I'm looking for a library (or plugin) that help me create a slideshow where (besides the simple ordering of images) I'm able to define the beginning and ending positions (either X/Y, or Zooms) for a given image and the plugin animates the intervening steps between them. Flash has a number of tools/libs like this, i'm sure jQuery has seen similar. Ideally something that offers a range of easing effects as well. I understand these elements are native to jQuery...i'm looking for a time-tested wrapper. thx

  • [Flex] Caching canvas into ByteArray

    - by Eugene
    Task: (all in code, not visual) create a canvas, place into it some labels and draw some lines, then cache it as byteArray. The problem is that if I cache an object that is already drawed on the screen, it works great, but if I cache a canvas, that have been created few lines earlier, this results white image. Is there any solution to cache a display object, that was created in code, but not intended to be displayed at all?

  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • Displaying xaml resources dynamically?

    - by Robert
    I used Mike Swanson's illustrator to xaml converter to convert some of my images to xaml. The convert creates a viewbox that contains the image. These viewboxes I made resource files in my program. The code below shows what I'm trying to do: I have a viewmodel that has an enum variable called PrimaryWinding of type Windings. The values PrimD and PrimY of the enum select the respective PrimD and PrimY xaml files in the resources. <UserControl.Resources> <DataTemplate x:Key="PrimTrafo" DataType="{x:Type l:Windings}"> <Frame Source="{Binding}" x:Name="PART_Image" NavigationUIVisibility="Hidden"> <Frame.LayoutTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Frame.LayoutTransform> </Frame> <DataTemplate.Triggers> <DataTrigger Binding="{Binding}" Value="PrimD"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimD.xaml" /> </DataTrigger> <DataTrigger Binding="{Binding}" Value="PrimY"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimY.xaml" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </UserControl.Resources> <!--The contentcontrol that holds the datatemplate defined above--> <Grid > <Grid.ColumnDefinitions> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="1*"></ColumnDefinition> </Grid.ColumnDefinitions> <ContentControl Grid.Column="0" Content="{Binding PrimaryWinding}" ContentTemplate="{StaticResource PrimTrafo}"/> </Grid> This code works. Only I can't resize the drawings to the size of the grid cell. I added the ScaleTransform class to resize the image. Is a Frame the wrong class to hold the drawings? Should I use the ScaleTransform class to resize the drawing to the size of the cell? And how can I do that dynamically?

  • Images inside of UILabel

    - by enby
    hello everyone! I'm trying to find the best way to display images inside of UILabels (in fact, I wouldn't mind switching to something other than UILabel if it supports images with no hassle) The scenario is: I have a table view with hundreds of cells and UILabel being the main component of each cell The text I assign to each cell contains sequences of characters that need to be parsed out and represented as an image In simpler words, imagine a TableView of an instant messenger that parses replaces all ":)", ":(", ":D" etc with corresponding smiley images Any input would be greatly appreciated!

  • how can I change top-margin the right way if multiple css class assigned?

    - by Radek
    I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down. I did so by .menu_about_author { margin-top:40px; } but it didn't work any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png

    Input: I have a LaTeX file, with plain text & math formulas.

  • Finding web source of Drag&Drop with Qt

    - by UncaughtException
    I'm trying to implement a simple notebook in Qt. Microsoft OneNote allows text or an image from a website to be inserted by Drag&Drop with an attached link to the source that looks like this for the stackoverflow logo on the 'ask' page: Inserted from <http://stackoverflow.com/questions/ask. With the QT dropsite example, I examined all the information thats transported by the QMimeData object, but didn't find something really helpful. Do you know a way to do this in pure Qt or at least with not so much platform-dependant code?
