  • SubViewTwoController undeclared (first use in this function) (obj-c)

    - by benny
    Ahoy hoy everyone :) Here is a list of links. You will need it when reading the post. I am a newbie to Objective-C and try to learn it for iPhone-App-Development. I used the tutorial linked in the link list to create a standard app with a simple basic Navigation. This app contains a "RootView" that is displayed at startup. The startup screen itself contains three elements wich all link to SubViewOne. I have got it to work this far. So what i want to change is to make the second element link to SubViewTwo. When i "Build and Go" it, i get the following errors: RootViewController.m: SubViewTwoController *subViewTwoController = [[SubViewTwoController alloc] init]; // SubViewTwoController undeclared (first use in this function) and in SubViewTwoController.m [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview no superclass declared in @interface for ´SubViewTwoController´ and the same thing after - (void)dealloc { [super dealloc]; I think you will also need the header files, so here they are! RootViewController.h #import <UIKit/UIKit.h> @interface RootViewController : UITableViewController { IBOutlet NSMutableArray *views; } @property (nonatomic, retain) IBOutlet NSMutableArray *views; @end SubViewOneController.h #import <UIKit/UIKit.h> @interface SubViewOneController : UIViewController { IBOutlet UILabel *label; IBOutlet UIButton *button; } @property (retain,nonatomic) IBOutlet UILabel *label; @property (retain,nonatomic) IBOutlet UIButton *button; - (IBAction) OnButtonClick:(id) sender; @end and SubViewTwoController.h #import <UIKit/UIKit.h> @interface SubViewTwo : UIViewController { IBOutlet NSMutableArray *views; } @end I would be really great if you would leave your ideas with a short explanation. Thanks a lot in advance! benny

  • Convert a Relative URL to an Absolute URL in Actionscript / Flex

    - by Bear
    I am working with Flex, and I need to take a relative URL source property and convert it to an absolute URL before loading it. The specific case I am working with involves tweaking SoundEffect's load method. I need to determine if a file will be loaded from the local file system or over the network from looking at the source property, and the easiest way I've found to do this is to generate the absolute URL. I'm having trouble generating the absolute URL for sound effect in particular. Here were my initial thoughts, which haven't worked. Look for the DisplayObject that the Sound Effect targets, and use its loaderInfo property. The target is null when the SoundEffect loads, so this doesn't work. Look at FlexGlobals.topLevelApplication, at the url or loaderInfo properties. Neither of these are set, however. Look at the FlexGlobals.topLevelApplication.systemManager.loaderInfo. This was also not set. The SoundEffect.as code basically boils down to var url:String = "mySound.mp3"; /*>> I'd like to convert the URL to absolute form here and tweak it as necessary <<*/ var req:URLRequest = new URLRequest(url); var loader:Loader = new Loader(); loader.load(req); Does anyone know how to do this? Any help clarifying the rules of how relative urls are resolved for URLRequests in ActionScript would also be much appreciated. edit I would also be perfectly satisfied with some way to tell whether the url will be loaded from the local file system or over the network. Looking at an absolute URL it would just be easy to look at the prefix, like file:// or http://.

  • Create Folders from text file and place dummy file in them using a CustomAction

    - by Birkoff
    I want my msi installer to generate a set of folders in a particular location and put a dummy file in each directory. Currently I have the following CustomActions: <CustomAction Id="SMC_SetPathToCmd" Property="Cmd" Value="[SystemFolder]cmd.exe"/> <CustomAction Id="SMC_GenerateMovieFolders" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (echo %a)" /> <CustomAction Id="SMC_CopyDummyMedia" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (copy [MBSAMPLECOLLECTIONS]dummy.avi &quot;%a&quot;\&quot;%a&quot;.avi)" /> These are called in the InstallExecuteSequence: <Custom Action="SMC_SetPathToCmd" After="InstallFinalize"/> <Custom Action="SMC_GenerateMovieFolders" After="SMC_SetPathToCmd"/> <Custom Action="SMC_CopyDummyMedia" After="SMC_GenerateMovieFolders"/> The custom actions seem to start, but only a blank command prompt window is shown and the directories are not generated. The files needed for the customaction are copied to the correct directory: <Directory Id="WIX_DIR_COMMON_VIDEO"> <Directory Id="MBSAMPLECOLLECTIONS" Name="MB Sample Collections" /> </Directory> <DirectoryRef Id="MBSAMPLECOLLECTIONS"> <Component Id="SampleCollections" Guid="C481566D-4CA8-4b10-B08D-EF29ACDC10B5" DiskId="1"> <File Id="movies.txt" Name="movies.txt" Source="SampleCollections\movies.txt" Checksum="no" /> <File Id="series.txt" Name="series.txt" Source="SampleCollections\series.txt" Checksum="no" /> <File Id="dummy.avi" Name="dummy.avi" Source="SampleCollections\dummy.avi" Checksum="no" /> </Component> </DirectoryRef> What's wrong with these Custom Actions or is there a simpler way to do this?

  • Can I use a *.tag from another *.tag file in the same /WEB-INF/tags folder?

    - by Ytsejammer
    Hello, I am trying to refactor my JSP code so that a small conditional test condition gets reused through a *.tag file. There are some big parts of my UI that depend on the value of a two-state property of an object present in the request. Let's say the property is 'gender' and the object is of type Person. Like I said, I would like to simplify & centralize the test on the gender property using a tag. For this purpose, I created two tag files: /WEB-INF/tags/if-male.tag /WEB-INF/tags/if-female.tag Now, I have another tiny spot that gets repeated in all over my application; let's say is the salutation to my site user. With this idea, I created a tag like this: /WEB-INF/tags/salutation.tag As you can imagine, I am trying to use the if-male/if-female test within the salutation.tag file to output 'Mrs.' or 'Mr.' like this: <%@ tag body-content="empty" %> <%@ taglib prefix="g" uri="/WEB-INF/tags" %> <g:if-male> Mr. </g:if-male> <g:if-female> Mrs. </g:if-female> Is the use of the if-male/if-female tags legal within the salutation.tag file? I have tried with such arrangement, but it looks like the JDeveloper 10.1.3.4 compiler gets confused and cannot deal with the salutation.tag tag invoking the other two tags in the same 'library' (folder under /WEB-INF/tags). The reference works perfectly in Jetty 6 and it looks like it works as well if I deploy the application to OC4J directly without relying on JDeveloper to pre-compile all my JSPs. I hope someone can shed some light on this. Thanks, YJ

  • Disable Painting of the VScrollbar in a System.Windows.Forms.RichTextBox

    - by SchlaWiener
    I have a custom control inherited from RichTextBox. This control has the ability to "disable" rich text editing. I achive this by just setting the Rtf property to the text property during the TextChanged event. this is how my code looks like: private bool lockTextChanged; void RichTextBox_TextChanged(object sender, EventArgs e) { // prevent StackOverflowException if (lockTextChanged) return; // remember current position int rtbstart = rtb.SelectionStart; int len = rtb.SelectionLength; // prevent painting rtb.SuspendLayout(); // set the text property to remove the entire formatting. lockTextChanged = true; rtb.Text = rtb.Text; rtb.Select(rtbstart, len); lockTextChanged = false; rtb.ResumeLayout(true); } That worked well. However in a large text with like 200 lines the controls jitters (you see the first lines of text for the wink). To prevent that from happening I filter the WM_PAINT between SuspendLayout() and ResumeLayout() private bool layoutSuspended; public new void SuspendLayout() { layoutSuspended = true; base.SuspendLayout(); } public new void ResumeLayout() { layoutSuspended = false; base.ResumeLayout(); } public new void ResumeLayout(bool performLayout) { layoutSuspended = false; base.ResumeLayout(performLayout); } private const int WM_PAINT = 0x000F; protected override void WndProc(ref System.Windows.Forms.Message m) { if (!(m.Msg == WM_PAINT && layoutSuspended)) base.WndProc(ref m); } that did the trick, the RichTextBox isn't jittering anymoe. That's what I wanted to achive, except one thing: The scrollbar is still jittering everytime I type text to my control. Now my question: Does anyone have a clue for me how to prevent the scrollbar from redrawing during Suspend/Resume Layout?

  • Silverlight MVVM binding seems not to work

    - by Savvas Sopiadis
    Hi everybody! Building my first SL MVVM application (Silverlight4 RC) and have some issues i don't understand. Having a WPF background i don't know what is going on here: ViewModel has several properties, in which one is called SelectedRecord. This is a get only property and is defined like this: public Culture SelectedRecord { get { return culturesView.View.CurrentItem as Culture; } } As you can see it is gets the current value of a CollectionViewSource (called culturesView). So if i select a Culture, the SelectedRecord (gets a value directly from within the CollectionViewSource) as expected. (Actually there is a datagrid control bound to the CollectionViewSource, hence it is possible to change the selected item) OK. Now to the View . There are several views which access this ViewModel and in particular there is one which shows the values of the aforementioned property SelectedRecord (let's call it the EditView). To show this EditView there is a button (which has its Command property bound to an ICommand in the ViewModel) which functions (the first time) as expected. This means: 1st try : i select a record, switch to EditView, outcome: selected record values are shown (as expected!!). 2nd try: switch back to datagrid, select another record, switch to EditView, outcome: the values of the previous shown record are shown again!!! WHY?? First i thought that the SelectedRecord has not the correct value set, but i was mistaken: it HAS the correct value! So it should be shown!? What am i missing? In WPF this would work!! Thanks in advance

  • First run notepad with my.cfg and only then start the service

    - by Viv Coco
    Hi all, I install along with my application: 1) a service that starts and stops my application as needed 2) a conf file that contains actually the user data and that will be shown to the user to modify as needed (I give the user the chance to change it by running notepad.exe with my conf file during installing) The problem is that in my code the service I install starts before the user had the chance to modify the conf file. What I would like is: 1) first the user gets the chance to change the conf file (run notepad.exe with the conf file) 2) only afterward start the service <Component Id="MyService.exe" Guid="GUID"> <File Id="MyService.exe" Source="MyService.exe" Name="MyService.exe" KeyPath="yes" Checksum="yes" /> <ServiceInstall Id='ServiceInstall' DisplayName='MyService' Name='MyService' ErrorControl='normal' Start='auto' Type='ownProcess' Vital='yes'/> <ServiceControl Id='ServiceControl' Name='MyService' Start='install' Stop='both' Remove='uninstall'/> </Component> <Component Id="my.conf" Guid="" NeverOverwrite="yes"> <File Id="my.cfg" Source="my.cfg_template" Name="my.cfg" KeyPath="yes" /> </Component> [...] <Property Id="NOTEPAD">Notepad.exe</Property> <CustomAction Id="LaunchConfFile" Property="NOTEPAD" ExeCommand="[INSTALLDIR]my.cfg" Return="ignore" Impersonate="no" Execute="deferred"/> <!--Run only on installs--> <InstallExecuteSequence> <Custom Action='LaunchConfFile' Before='InstallFinalize'>(NOT Installed) AND (NOT UPGRADINGPRODUCTCODE)</Custom> </InstallExecuteSequence> What am I doing wrong in the above code and how could I change it in order to achieve what I need?

  • Is using YIELD a read-only way to return a collection?

    - by Eric
    I'm writing an interface which has a collection property which I want to be read only. I don't want users of the interface to be able to modify the collection. The typical suggestion I've found for creating a read only collection property is to set the type of the property to IEnumerable like this: private List<string> _mylist; public IEnumerable<string> MyList { get { return this._mylist; } } Yet this does not prevent the user from casting the IEnumerable back to a List and modifying it. If I use a Yield keyword instead of returning _mylist directly would this prevent users of my interface from being able to modify the collection. I think so because then I'm only returning the objects one by one, and not the actual collection. private List<string> _mylist; public IEnumerable<string> MyList { get { foreach(string str in this._mylist) { yield return str; } } }

  • Partial template specialization: matching on properties of specialized template parameter

    - by Kenzo
    template <typename X, typename Y> class A {}; enum Property {P1,P2}; template <Property P> class B {}; class C {}; Is there any way to define a partial specialization of A such that A<C, B<P1> > would be A's normal template, but A<C, B<P2> > would be the specialization? Replacing the Y template parameter by a template template parameter would be nice, but is there a way to partially specialize it based on P then? template <typename X, template <Property P> typename Y> class A {}; // template <typename X> class A<X,template<> Y<P2> > {}; <-- not valid Is there a way by adding traits to a specialization template<> B<P2> and then using SFINAE in A?

  • datepicker value is blank when disabled, jquery

    - by Mithil Deshmukh
    Hi. I'm fairly new to jQuery. I have a Jquery datepicker in a user control. I have added a "disable" property to the datepicker. Whenever I save the page(having this usercontrol) the datepicker with disable set to true is empty. All other datepickers save fine. Here is my code. ASPX < USERCONTROL:DATEPICKER id="dpBirthDate" startyear="1980" runat="server" Disable=true ASCX < input type="text" size="8" runat="server" id="txtDate" name="txtDate" onblur="ValidateForm(this.id);" / ASCX Code Behind Public Property Disable() As Boolean Get Return (txtDate.Disabled = True) End Get Set(ByVal bValue As Boolean) If (bValue = True) Then txtDate.Attributes.Add("Disabled", "True") Else txtDate.Attributes.Remove("Disabled") End If End Set End Property My Jquery $(document).ready(function() { $("input[id$=txtDate]").datepicker({ showOn: 'button', buttonImage: '<%=ConfigurationSettings.AppSettings("BASE_DIRECTORY")%>/Images/el-calendar.gif', buttonImageOnly: true }); $("input[id$=txtDate]").mask("99/99/9999", { placeholder: " " }); //Disable datepicker if "disable=true" $("input[id$=txtDate]").each(function() { if ($("input[id$=" + this.id + "]").attr("Disabled") == "True") { $("input[id$=" + this.id + "]").datepicker("disable"); } else if ($("input[id$=" + this.id + "]").attr("Disabled") == "False") { $("input[id$=" + this.id + "]").datepicker("enable"); } }); }); I am sorry, I am not sure how to format the code here. I apologies for the cluttered code. Can anybody tell me why the datepicker value is empty when it is disabled but works fine otherwise? Thanks is advance.

  • Checked status not updated in CheckBox template

    - by Simon
    Hey there. I'm trying to create an hyperlink that changes its text depending on a boolean value. I thought I could leverage the IsChecked method of a CheckBox. So I wrote this ControlTemplate for a CheckBox: <CheckBox Checked="CheckBox_Checked" IsChecked="{Binding Path=SomeBool, Mode=TwoWay}"> <CheckBox.Template> <ControlTemplate TargetType="{x:Type CheckBox}"> <BulletDecorator> <BulletDecorator.Bullet> <TextBlock> <Hyperlink> <TextBlock x:Name="TextBoxHyperlink">Unchecked</TextBlock> </Hyperlink> </TextBlock> </BulletDecorator.Bullet> <ContentPresenter /> </BulletDecorator> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter TargetName="TextBoxHyperlink" Property="Text" Value="Checked" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </CheckBox.Template> </CheckBox> But when I click on the hyperlink, nothing happens. The checked status is not changed and the Text property of the TextBlock is not updated. Any ideas?

  • [Cocoa] Binding CoreData Managed Object to NSTextFieldCell subclass

    - by ndg
    I have an NSTableView which has its first column set to contain a custom NSTextFieldCell. My custom NSTextFieldCell needs to allow the user to edit a "desc" property within my Managed Object but to also display an "info" string that it contains (which is not editable). To achieve this, I followed this tutorial. In a nutshell, the tutorial suggests editing your Managed Objects generated subclass to create and pass a dictionary of its contents to your NSTableColumn via bindings. This works well for read-only NSCell implementations, but I'm looking to subclass NSTextFieldCell to allow the user to edit the "desc" property of my Managed Object. To do this, I followed one of the articles comments, which suggests subclassing NSFormatter to explicitly state which Managed Object property you would like the NSTextFieldCell to edit. Here's the suggested implementation: @implementation TRTableDescFormatter - (BOOL)getObjectValue:(id *)anObject forString:(NSString *)string errorDescription:(NSString **)error { if (anObject != nil){ *anObject = [NSDictionary dictionaryWithObject:string forKey:@"desc"]; return YES; } return NO; } - (NSString *)stringForObjectValue:(id)anObject { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; return [anObject valueForKey:@"desc"]; } - (NSAttributedString*)attributedStringForObjectValue:(id)anObject withDefaultAttributes:(NSDictionary *)attrs { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; NSAttributedString *anAttributedString = [[NSAttributedString alloc] initWithString: [anObject valueForKey:@"desc"]]; return anAttributedString; } @end I assign the NSFormatter subclass to my cell in my NSTextFieldCell subclass, like so: - (void)awakeFromNib { TRTableDescFormatter *formatter = [[[TRTableDescFormatter alloc] init] autorelease]; [self setFormatter:formatter]; } This seems to work, but is extremely patch. On occasion, clicking to edit a row will cause its value to nullify. On other occasions, the value you enter on one row will populate other rows within the table. I've been doing a lot of reading on this subject and would really like to get to the bottom of this. What's more frustrating is that my NSTextFieldCell is rendering exactly how I would like it to. This editing issue is my last obstacle! If anyone can help, that would be greatly appreciated.

  • Embedded Jetty resourceBase classpath URL

    - by drewzilla
    I'm embedding Jetty in a Spring based application. I configure my Jetty server in a Spring context file. The specific part of the configuration I'm having trouble with is this: <bean class="org.eclipse.jetty.webapp.WebAppContext"> <property name="contextPath" value="/" /> <property name="resourceBase" value="????????" /> <property name="parentLoaderPriority" value="true" /> </bean> If you see above, where I've put the ????????, I ideally want the resourceBase to reference a folder on my classpath. I'm deploying my application in a single executable JAR file and have a folder config/web/WEB-INF on my classpath. Jetty seems to be able to handle URLs defined in the resourceBase (e.g. jar:file:/myapp.jar!/config/web) but it doesn't seem to support classpath URLs. I get an IllegalArgumentException if I define something like classpath:config/web. This is a real pain for me. Does anyone know of anyway to achieve this functionality? Thanks, Andrew

  • Loading 2 Singletons With Dependencies when an app is opened (appDelegate / appDidBecomeActive) iPhone SDK

    - by taber
    I'm trying to load two standard-issue style singletons: http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html when my iPhone app is loaded. Here's my code: - (void) applicationDidFinishLaunching:(UIApplication *)application { // first, restore user prefs [AppState loadState]; // then, initialize the camera [[CameraModule sharedCameraModule] initCamera]; } My "camera module" has code that checks a property of the AppState singleton. But I think what's happening is a race condition where the camera module singleton is trying to access the AppState property while it's in the middle of being initialized (so the property is nil, and it's re-initializing AppState). I'd really like to keep these separate, instead of just throwing one (or both) into the App Delegate. Has anyone else seen something like this? What kind of workaround did you use, or what would you suggest? Thanks in advance! Here's the loadState method: + (void)loadState { @synchronized([AppState class]) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *file = [documentsDirectory stringByAppendingPathComponent:@"prefs.archive"]; Boolean saveFileExists = [[NSFileManager defaultManager] fileExistsAtPath:file]; if(saveFileExists) { sharedAppState = [[NSKeyedUnarchiver unarchiveObjectWithFile:file] retain]; } else { [AppState sharedAppState]; } } }

  • how to set SqlMapClient outside of spring xmls

  • C# How to commit a TextBox?

    - by Jake
    Hi, In a form, I have a TextBox Binding an Object on its member property "Title". Along with it is a "Save" button to test the binding. Seems like the underlying object property does not get updated unless the textbox loses focus. But there no form.ActiveControl.Blur() for use. Besides, this does not seem like a sound hack. Anyway to do this better? Thanks. EDIT: Sorry for not being clear. My question is in the title: "How to commit a TextBox". I use the term "commit" from the DataGridView commit and BindingSource commit. And it's in WinForms. (Have never worked with WPF, so it didn't occur to me. Sorry). The actual scenario I have is I have a bunch of TextBox binded to property of a single Object. The user enters values in all the TextBox and when the user clicks save (toolbar button), the last TextBox is still in focus (or in editing mode) hence the save will not capture the last value in the last textbox. I want to find the correct way to "commit" the textbox value just before saving. Thanks.

  • UIWebview does not show up into UINavigationController

    - by Pato
    Hi I have a tabBar application. In the first tab, I have a navigation bar. In this navigation bar I have a table view. When the user clicks a cell of the table, it goes to another table view, and when the user clicks a cell in that table, it goes to a webview to open a web page. Basically, it goes fine until opening the webview. In the webview, viewDidLoad is called and seems to work properly. However, webViewDidStartLoad is never called and the web page never shows up. I am not using IB. I build the UITabBarController in the AppDelegate, where I also assign an instance of my UINavigationController for each tab. I call the webview from the second UITableViewController as follows: rssWebViewController = [[webViews objectAtIndex: indexPath.row] objectForKey:@"controller"]; [[self navigationController] pushViewController:rssWebViewController animated:YES]; I have checked that the navigationController is there and it seems just fine. The viewDidload of my webview is as follows: - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = self.storyUrl; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [[self rssWebView] setDelegate: self]; [[self view] addSubview:[self rssWebView]]; [rssWebView loadRequest:requestObj]; self.rssWebView.scalesPageToFit = YES; self.rssWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); } The web view controller interface is defined as follows: @interface RSSWebViewController : UIViewController <UIWebViewDelegate>{ IBOutlet UIWebView *rssWebView; IBOutlet NSString *storyUrl; IBOutlet NSString *feedName; } @property (nonatomic, retain) IBOutlet UIWebView *rssWebView; @property (nonatomic, retain) IBOutlet NSString *storyUrl; @property (nonatomic, retain) IBOutlet NSString *feedName; @end Any help is greatly appreciated.

  • Best way to databind a Winforms control to a nullable type?

    - by Steve Hiner
    I'm currently using winforms databinding to wire up a data editing form. I'm using the netTiers framework through CodeSmith to generate my data objects. For database fields that allow nulls it creates nullable types. I've found that using winforms databinding the controls won't bind properly to nullable types. I've seen solutions online suggesting that people create new textbox classes that can handle the nullable types but that could be a pain having to swap out the textboxes on the forms I've already created. Initially I thought it would be great to use an extension method to do it. Basically creating an extension property for the textbox class and bind to that. From my limited extension method experience and doing a bit of checking online it looks like you can't do an extension property. As far as I can tell, binding has to be through a property since it needs to be able to get or set the value so an extension method wouldn't work. I'd love to find a clean way to retrofit these forms using something like extension methods but if I have to create new textbox and combo box controls that's what I'll do. My project is currently limited to .Net 2.0 due to the requirement to run on Windows 2000. Any suggestions?

  • NSMutableDictionary isn't stick around long enough

    - by Sean Danzeiser
    Sorry, beginner here . . . So I create an NSMutableDictionary in my app delegate when the application launches, and then later pass it on to a view controller, as it contains options for the VC like a background image, a url I want to parse, etc. Anyway, i wrote a custom init method for the VC, initWithOptions, where I pass the dictionary on. I'm trying to use this dictionary later on in other methods - so I created a NSMutableDictionary property for my VC and am trying to store the passed options dictionary there. However, when I go to get the contents of that property in later methods, it returns null. If i access it from the init method, it works. heres some sample code: -(id)initWithOptions:(NSMutableDictionary *)options { self = [super init]; if (self) { // Custom initialization self.optionsDict = [[NSMutableDictionary alloc]initWithDictionary:options]; NSLog(@"dictionary in init method %@",self.optionsDict); that NSLog logs the contents of the dictionary, and it looks like its working. then later when I do this: - (void)viewDidLoad { SDJConnection *connection = [[SDJConnection alloc]init]; self.dataArray = [connection getEventInfoWithURL:[dict objectForKey:@"urlkey"]]; NSLog(@"dictionary in connection contains: %@", [dict objectForKey:@"urlkey"]); [_tableView reloadData]; the dictionary returns null. Ive tried adjusting the property attributes, and it didn't work with either strong or retain. Any ideas?? THANKS!!

  • Trouble passing JSP values to ActionForm (Struts)

    - by tacotime
    Hi, I am a newbie to Struts and have inherited a problem. I am trying to pass 3 values contained in the same table cell from a JSP to my ActionForm class. The first value (and others in the JSP) work fine, but for some reason the other two do not. I have the appropriate getters and setters, but only the first (newrecnum) shows up, the other two are null. Is there a limitation to only pass the first value? Or is there something else wrong? Here is the JSP code: <td> <html:text size="10" maxlength="10" property="newrecnum"/><br> <html:text size="5" maxlength="5" property="newrectime"/> <html:select property="newreccode" disabled="true"> <html:option value="YES">YES</html:option> <html:option value="NO">NO</html:option></html:select> </td> I can include the ActionForm code as well if needed. Thanks!

  • Objective-C Getter Memory Management

    I'm fairly new to Objective-C and am not sure how to correctly deal with memory management in the following scenario: I have a Core Data Entity with a to-many relationship for the key "children". In order to access the children as an array, sorted by the column "position", I wrote the model class this way: @interface AbstractItem : NSManagedObject { NSArray * arrangedChildren; } @property (nonatomic, retain) NSSet * children; @property (nonatomic, retain) NSNumber * position; @property (nonatomic, retain) NSArray * arrangedChildren; @end @implementation AbstractItem @dynamic children; @dynamic position; @synthesize arrangedChildren; - (NSArray*)arrangedChildren { NSArray* unarrangedChildren = [[self.children allObjects] retain]; NSSortDescriptor* sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"position" ascending:YES]; [arrangedChildren release]; arrangedChildren = [unarrangedChildren sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]]; [sortDescriptor release]; [unarrangedChildren release]; return [arrangedChildren retain]; } @end I'm not sure whether or not to retain unarrangedChildren and the returned arrangedChildren (first and last line of the arrangedChildren getter). Does the NSSet allObjects method already return a retained array? It's probably too late and I have a coffee overdose. I'd be really thankful if someone could point me in the right direction. I guess I'm missing vital parts of memory management knowledge and I will definitely look into it thoroughly.

  • Bizarre problem with WPF XAML file.

    - by paxdiablo
    I've just started a very simple WPF application which consists of a main large image and four smaller images. In order to assist with the layout, I created some JPEGs in MsPaint containing the images -2, -1, 0, +1 and +2 and just copied them into the top level of the project directory. The XAML segment contains, for the five images: <Image Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="4" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicture" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/zero.jpg" <Image Grid.Column="1" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus2.jpg" <Image Grid.Column="2" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus1.jpg" <Image Grid.Column="3" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus1.jpg" <Image Grid.Column="4" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus2.jpg" When I try to set the source property for the plus2 image, it complains with a dialog box stating: Property value is not valid. Details | V The file plus2.jpg is not part of the project or its 'Build Action' property is not set to 'Resource'. Yet if I rename the file to plus3.jpg or plus2x.jpg, I don't have that problem. Why is it complaining about plus2.jpg specifically?

  • What is the best database structure for this scenario?

    - by Ricketts
    I have a database that is holding real estate MLS (Multiple Listing Service) data. Currently, I have a single table that holds all the listing attributes (price, address, sqft, etc.). There are several different property types (residential, commercial, rental, income, land, etc.) and each property type share a majority of the attributes, but there are a few that are unique to that property type. My question is the shared attributes are in excess of 250 fields and this seems like too many fields to have in a single table. My thought is I could break them out into an EAV (Entity-Attribute-Value) format, but I've read many bad things about that and it would make running queries a real pain as any of the 250 fields could be searched on. If I were to go that route, I'd literally have to pull all the data out of the EAV table, grouped by listing id, merge it on the application side, then run my query against the in memory object collection. This also does not seem very efficient. I am looking for some ideas or recommendations on which way to proceed. Perhaps the 250+ field table is the only way to proceed. Just as a note, I'm using SQL Server 2012, .NET 4.5 w/ Entity Framework 5, C# and data is passed to asp.net web application via WCF service. Thanks in advance.

  • Javascript problem with location.href.

    - by Patrick
    Hello! I have a textbox and whenever the user presses a key it's checked to see if the user pressed enter. If the enter key is pressed, i want to add all the info in the textbox and transfer the user to a different url. <script language="javascript" type="text/javascript"> function checkEnter(e){ //e is event object passed from function invocation var characterCode; if(e && e.which){ //if which property of event object is supported (NN4) e = e; characterCode = e.which; //character code is contained in NN4's which property } else{ e = event; characterCode = e.keyCode; //character code is contained in IE's keyCode property } if (characterCode == 13) { //if generated character code is equal to ascii 13 (if enter key) var searchLink = '/Search/?Keywords=' + document.getElementById('<%= searchBox.ClientID %>').value; transferUser(searchLink); return false; } else{ return true; } } function transferUser(url) { window.location.href = url; window.location.replace(url); } </script> Search: <input name="ctl00$searchBox" type="text" id="ctl00_searchBox" class="header_line_search_box_textbox" onKeyPress="checkEnter(event);" /> I have tried every possible combination, but nothing happens. The site just refreshes itself. I also need somehow to convert the text from the user to html safe, must like the HttpUtility.EncodeUrl in aspx.
