  • Slider value available between different cocoa classes

    - by Miguel Bayona
    I am playing around with an iPhone app, and need to accomplish something that I am sure is very basic: I have a slider that is implemented in a Controller.m class. However, I need its value must be available in a different class, MainView.m class where I have defined an equation that depends on the value of the slider. How can I do it?? Thanks, Miguel Bayona

  • Dependency Property not getting updated value via ActivityBind

    - by d h
    I have a Sequence Activity which holds two activities (Activity A and B), the input dependency property for Activity B is bound an output dependency property of Activity A. However, when I run the sequence activity, the Input for activity B is never updated and just uses the default value of activity A's output. My question is: is there a way to enforce an update on activity B's input so that it gets the latest value of activity A's output?

  • Drupal Forms - Setting a Default Value

    - by JR
    I am using the webform module for Drupal 6 and would like to set a default value for the confirmation message of the webform whenever it is created. Would I have to create my own module to set this form value whenever a user creates a new webform? Or would I have to implement a special hook to look for when a webform is created?

  • Regex Query to get string value

    - by Alex
    Hi all, I am looking for a regex query that would allow me to retrieve a value from a string here are examples of my string: home.aspx?StudyID=0020101&aa=72 randompage.aspx?studyid=3023603&aa=40 myconfig.aspx?studyid=0021600&aa=40 I need to get the numerical value of the 'studyid' variable, please note that the name of the page will change so simply doing the substring and counting char spaces didn't work I unfortunately cannot use request.querystring method as this string is stored in the database and a select statement will be used for running this regex query Thanks

  • Adding objects to an NSMutableArray, order seems odd when parsing from an XML file

    - by diatrevolo
    Hello: I am parsing an XML file for two elements: "title" and "noType". Once these are parsed, I am adding them to an object called aMaster, an instance of my own Master class that contains NSString variables. I am then adding these instances to an NSMutableArray on a singleton, in order to call them elsewhere in the program. The problem is that when I call them, they don't seem to be on the same NSMutableArray index... each index contains either the title OR the noType element, when it should be both... can anyone see what I may be doing wrong? Below is the code for the parser. Thanks so much!! #import "XMLParser.h" #import "Values.h" #import "Listing.h" #import "Master.h" @implementation XMLParser @synthesize sharedSingleton, aMaster; - (XMLParser *) initXMLParser { [super init]; sharedSingleton = [Values sharedValues]; aMaster = [[Master init] alloc]; return self; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { aMaster = [[Master alloc] init]; //Extract the attribute here. if ([elementName isEqualToString:@"intro"]) { aMaster.intro = [attributeDict objectForKey:@"enabled"]; } else if ([elementName isEqualToString:@"item"]) { aMaster.item_type = [attributeDict objectForKey:@"type"]; //NSLog(@"Did find item with type %@", [attributeDict objectForKey:@"type"]); //NSLog(@"Reading id value :%@", aMaster.item_type); } else { //NSLog(@"No known elements"); } //NSLog(@"Processing Element: %@", elementName); //HERE } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue appendString:string];//[tempString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; CFStringTrimWhitespace((CFMutableStringRef)currentElementValue); } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { [sharedSingleton.master addObject:aMaster]; NSLog(@"Added %@ and %@ to the shared singleton", aMaster.title, aMaster.noType); //Only having one at a time added... don't know why [aMaster release]; aMaster = nil; } else if ([elementName isEqualToString:@"title"]) { [aMaster setValue:currentElementValue forKey:@"title"]; } else if ([elementName isEqualToString:@"noType"]) { [aMaster setValue:currentElementValue forKey:@"noType"]; //NSLog(@"%@ should load into the singleton", aMaster.noType); } NSLog(@"delimiter"); NSLog(@"%@ should load into the singleton", aMaster.title); NSLog(@"%@ should load into the singleton", aMaster.noType); [currentElementValue release]; currentElementValue = nil; } - (void) dealloc { [aMaster release]; [currentElementValue release]; [super dealloc]; } @end
