  • Scheme sorting a list

    - by John
    Okay so I am trying to take in a list and sort it from greatest to smallest. Example: > (maxheap (list 5 6 2 1 18 7)) ;output: > (18 7 6 5 2 1) So here's what I got so far: (define (mkmaxheap heaplist) (let ((max (mymax(heaplist)))) ;mymax is a func that returns max number, it works (let (( head (car heaplist)) (tail (cdr heaplist))) (if (null? tail) newlist)))) Thats all I could get to compile, all the other code I wrote failed. Any help on solving this would be much appreciated.

  • iphone image is leaking, but where?

    - by Brodie4598
    the image that is being displayed in this code is leaking but I cant figure out how. What I have a tableview that displays images to be displayed. Each time a user selects an image, it should remove the old image, download a new one, then add it to the scroll view. But the old image is not being released and I cant figure out why... -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [imageView removeFromSuperview]; self.imageView = nil; NSUInteger row = [indexPath row]; NSString *tempC = [[NSString alloc]initWithFormat:@"http://www.website.com/%@_0001.jpg",[pdfNamesFinalArray objectAtIndex:row] ]; chartFileName = tempC; pdfName = [pdfNamesFinalArray objectAtIndex:row]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docsPath = [paths objectAtIndex:0]; NSString *tempString = [[[NSString alloc]initWithFormat:@"%@/%@.jpg",docsPath,pdfName]autorelease]; NSData *data = [NSData dataWithContentsOfFile:tempString]; if (data != NULL){ self.imageView = nil; [imageView removeFromSuperview]; self.imageView = nil; UIImageView *tempImage = [[[UIImageView alloc]initWithImage:[UIImage imageWithData:data]]autorelease]; self.imageView = tempImage; [data release]; scrollView.contentSize = CGSizeMake(imageView.frame.size.width , imageView.frame.size.height); scrollView.maximumZoomScale = 1; scrollView.minimumZoomScale = .6; scrollView.clipsToBounds = YES; scrollView.delegate = self; [scrollView addSubview:imageView]; scrollView.zoomScale = .37; } else { [data release]; self.imageView = nil; [imageView removeFromSuperview]; self.imageView = nil; activityIndicator.hidden = NO; getChartsButton.enabled = NO; chartListButton.enabled = NO; saveChartButton.enabled = NO; [NSThread detachNewThreadSelector:@selector(downloadImages) toTarget:self withObject:nil]; } chartPanel.hidden = YES; } -(void) downloadImages { NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; self.imageView = nil; [imageView removeFromSuperview]; NSURL *url = [[[NSURL alloc]initWithString:chartFileName]autorelease]; NSData *data = [NSData dataWithContentsOfURL:url]; UIImageView *tempImage = [[[UIImageView alloc]initWithImage:[UIImage imageWithData:data]]autorelease]; self.imageView = tempImage; tempImage = nil; scrollView.contentSize = CGSizeMake(imageView.frame.size.width , imageView.frame.size.height); scrollView.maximumZoomScale = 1; scrollView.minimumZoomScale = .37; scrollView.clipsToBounds = YES; scrollView.delegate = self; [scrollView addSubview:imageView]; scrollView.zoomScale = .6; activityIndicator.hidden = YES; getChartsButton.enabled = YES; chartListButton.enabled = YES; saveChartButton.enabled = YES; [pool drain]; [pool release]; }

  • Precompile Lambda Expression Tree conversions as constants?

    - by Nathan
    It is fairly common to take an Expression tree, and convert it to some other form, such as a string representation (for example this question and this question, and I suspect Linq2Sql does something similar). In many cases, perhaps even most cases, the Expression tree conversion will always be the same, i.e. if I have a function public string GenerateSomeSql(Expression<Func<TResult, TProperty>> expression) then any call with the same argument will always return the same result for example: GenerateSomeSql(x => x.Age) //suppose this will always return "select Age from Person" GenerateSomeSql(x => x.Ssn) //suppose this will always return "select Ssn from Person" So, in essence, the function call with a particular argument is really just a constant, except time is wasted at runtime re-computing it continuously. Assuming, for the sake of argument, that the conversion was sufficiently complex to cause a noticeable performance hit, is there any way to pre-compile the function call into an actual constant?

  • PredicateBuilder "And" Method not working

    - by mikemurf22
    I have downloaded the predicate builder and am having a difficult time getting it to work with the entity framework. Here is my code: v_OrderDetail is the entity var context = new OrdersEntities(); Expression<Func<v_OrderDetail,bool>> whereClause = w => true; var predicate = PredicateBuilder.True<v_OrderDetail>(); predicate.And(w => w.Status == "Work"); var results = context.v_OrderDetail.AsExpandable().Where(predicate); When I look at the results I get back every order. The And predicate doesn't seem to take. When I look at the predicate.parameters.count it only shows 1. I'm not sure, but I would expect it to show 2 after I add the second one. Any help is greatly appreciated.

  • Are these two functions overkill for sanitization?

    - by jpjp
    function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } function sanitizeMySQL($var) { $var = mysql_real_escape_string($var); $var = sanitizeString($var); return $var; } I got these two functions from a book and the author says that by using these two, I can be extra safe against XSS(the first function) and sql injections(2nd func). Are all those necessary? Also for sanitizing, I use prepared statements to prevent sql injections. I would use it like this: $variable = sanitizeString($_POST['user_input']); $variable = sanitizeMySQL($_POST['user_input']);

  • Difference between URLLIB2 call in IDLE and from Django?

  • Unable to catch exception from Activator.CreateInstance.

    - by Patrik Hägne
    OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

  • Is it possible to define a generic lambda?

    - by Mike OBrien
    I have some logic in a method that operates on a specified type and I'd like to create a generic lambda that encapsulates the logic. This is the spirit of what I'm trying to do: public void DoSomething() { // ... Func<T> GetTypeName = () => T.GetType().Name; GetTypeName<string>(); GetTypeName<DateTime>(); GetTypeName<int>(); // ... } I know I can pass the type as a parameter or create a generic method but I'm interested if it can just be a generic lambda (So I'm not looking for alternatives). From what I can tell C# 3.0 doesn't support this. TIA, m

  • adhoc struct/class in C#?

    - by acidzombie24
    Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

How would this be done without pointers, if possible?

  • How do I improve the efficiency of the queries executed by this generic Linq-to-SQL data access clas

    - by Lee D
    Hi all, I have a class which provides generic access to LINQ to SQL entities, for example: class LinqProvider<T> //where T is a L2S entity class { DataContext context; public virtual IEnumerable<T> GetAll() { return context.GetTable<T>(); } public virtual T Single(Func<T, bool> condition) { return context.GetTable<T>().SingleOrDefault(condition); } } From the front end, both of these methods appear to work as you would expect. However, when I run a trace in SQL profiler, the Single method is executing what amounts to a SELECT * FROM [Table], and then returning the single entity that meets the given condition. Obviously this is inefficient, and is being caused by GetTable() returning all rows. My question is, how do I get the query executed by the Single() method to take the form SELECT * FROM [Table] WHERE [condition], rather than selecting all rows then filtering out all but one? Is it possible in this context? Any help appreciated, Lee

  • Trouble with datasource not being called from viewWillAppear

    - by user278859
    A little background. I have taken GCCalendar which only works in portrait orientation and extended it to work in landscape similar to how the iPhone's Calendar app works. I did this by duplicating the main view class and modifying it to work in landscape. So when the phone is in portrait orientation the CGCalendar is instantiated from the apps main view controller using the original portrait view class and when in landscape orientation using the new modified landscape view class. Most of the other classes in GCCalendar are shared without modification. A few had to be duplicated as well. I got it all working great except for an issue with the datasource. The datasource is called when the calendar is first loaded and each time the user changes the dates being viewed. Problem is I can't get the datasource call to work on the first call. I am stumped as it works fine in portrait orientation and I cannot find any difference between the 2 versions. Following is some of the code that shows how it gets to the datasource call the first time. Subsequent calls removes all the calendar subviews and instantiates them again with the new dates. The duplicated landscape class names end in LS. Otherwise as you can see they are identical. Does anyone has any idea of where else I might look to resolve this issue? Thanks, John -------------------------------- //App main view controller - (void)showLandscapeCalendar { GCCalendarLandscapeView *calendar = [[[GCCalendarLandscapeView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (void)showPortraitCalendar { GCCalendarPortraitView *calendar = [[[GCCalendarPortraitView alloc] init] autorelease]; calendar.dataSource = self; calendar.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:calendar]; [self presentModalViewController:navigationController animated:YES]; } - (NSArray *)calendarEventsForDate:(NSDate *)date{ //build and return the events array //this is the protocol datasource method //It is supposed to run every time the date changes in the calendar } ------------------------------- // GCCalendarLandscapeView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayViewLS *nextDayView = [[GCCalendarDayViewLS alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayViewLS - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { //** first time through the dataSource method does not run events = [dataSource calendarEventsForDate:date]; } ------------------------------- // GCCalendarPortraitView... - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (viewDirty) { [self reloadDayAnimated:NO context:NULL]; viewDirty = NO; } viewVisible = YES; } - (void)reloadDayAnimated:(BOOL)animated context:(void *)context { GCCalendarDayView *nextDayView = [[GCCalendarDayView alloc] initWithCalendarView:self]; } ------------------------------- //GCCalendarDayView - (id)initWithCalendarView:(GCCalendarView *)view { if (self = [super init]) { dataSource = view.dataSource; } return self; } - (void)reloadData { **//this one works every time events = [dataSource calendarEventsForDate:date]; }
