  • Binding to a List<object> in silverlight problem.

    - by cw
    Hello, Can someone suggest what I am doing wrong? Basically I have a List Items, when an item gets added to the list I am resetting the collection to the viewmodel property. The only way I can get it to work is if I null the member object out before reassigning the binding. Any suggestions on how to go about updating a UI when an item gets added to a List? public List<Item> RegisteredItems { get { return m_vRegisteredItems; } set { m_vRegisteredItems= null; NotifyPropertyChanged("RegisteredItems"); m_vRegisteredItems= value; NotifyPropertyChanged("RegisteredItems"); } }

  • PHP Check if <ul> has ended IF it exists

    - by Krewe
    I have my blog generate a preview by taking the first 300 characters and cut off the last whole word. My problem is, when I have a list near the top of the blog it is sometimes included in the preview, however the end list tag usually never is. So how can I check the $preview variable for a starting list tag, and if it is found, check for an ending tag and if it's not there add one. All the code for my preview. $preview = wordwrap($content, 300); $preview = explode("\n", $preview); $preview = $preview[0] . "...";

  • Removing items from lists and all references to them.

    - by LiamV
    I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node?

  • C++: incorrect swapping of nodes in linked list

    - by Dragon
    I have 2 simple structures: struct Address { char city[255]; }; typedef Address* AddressPtr; struct Person { char fullName[255]; Address* address; Person* next; }; typedef Person* PersonPtr; The Person structure forms the Linked list where new elements are added to the beginning of the list. What I want to do is to sort them by fullName. At first I tried to swap links, but I lost the beginning of the list and as a result my list was sorted partially. Then I decided to sort list by swapping the values of nodes. But I get strange results. For a list with names: Test3, Test2, Test1, I get Test3, Test3, Test3. Here is my sorting code: void sortByName(PersonPtr& head) { TaskPtr currentNode, nextNode; for(currentNode = head; currentNode->next != NULL; currentNode = currentNode->next) { for(nextNode = currentNode->next; nextNode != NULL; nextNode = nextNode->next) { if(strcmp(currentNode->fullName, nextNode->fullName) > 0) { swapNodes(currentNode, nextNode); } } } } void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_node = node2; strcpy(node2->fullName, node1->fullName); strcpy(node1->fullName, temp_node->fullName); strcpy(node2->address->city, node1->address->city); strcpy(node1->address->city, temp_node->address->city); } After the sorting completion, nodes values are a little bit strange. UPDATED This is how I swapped links void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_person; AddressPtr temp_address; temp_person = node2; node2 = node1; node1 = temp_person; temp_address = node2->address; node2->address = node1->address; node1->address = temp_address; }

  • time on files differ by 1 sec. FAIL Robocopy sync

    - by csmba
    I am trying to use Robocopy to sync (/IMG) a folder on my PC and a shared network drive. The problem is that the file attributes differ by 1 sec on both locations (creation,modified and access). So every time I run robocopy, it syncs the file again... BTW, problem is the same if I delete the target file and robocopy it from new... still, new file has 1 sec different properties. Env Details: Source: Win 7 64 bit Target: WD My Book World Edition NAS 1TB which takes its time from online NTP pool.ntp.org (I don't know if file system is FAT or not)

  • PHP: Fastest way possible to read contents of a file.

    - by SoLoGHoST
    Ok, I'm looking for the fastest possible way to read all of the contents of a file via php with a filepath on the server, also these files can be huge. So it's very important that it does a READ ONLY to it as fast as possible. Is reading it line by line faster than reading the entire contents? Though, I remember reading up on this some, that reading the entire contents can produce errors for huge files. Is this true?

  • Python check if object is in list of objects

    - by John
    Hi, I have a list of objects in Python. I then have another list of objects. I want to go through the first list and see if any items appear in the second list. I thought I could simply do for item1 in list1: for item2 in list2: if item1 == item2: print "item %s in both lists" However this does not seem to work. Although if I do: if item1.title == item2.title: it works okay. I have more attributes than this though so don't really want to do 1 big if statement comparing all the attributes if I don't have to. Can anyone give me help or advise on what I can do to find the objects which appear in both lists. Thanks

  • iOS - How to iterate through list of files on website directory

    - by svjim
    On iOS, I am looking for the proper way to return the URLs for a list of files that are in a directory. /images 1.jpg 2.jpg 3.jpg ... I know the URL for the directory and know all the files in the directory will be of type jpeg. It is not clear to me how to properly format the NSURLRequest to return the list of files in the images directory. Once the list is returned, I will iterate through it to return the individual images.

  • Getting a list of all phone contacts?

    - by pcm2a
    Simple enough question. I need to know the best way to get the same list of contacts that show up when a user presses the Contacts button. You would think something like this would work: //For Contacts Intent pickIntent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); //For Phones Intent pickIntent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); The problem is that does not include secondary google accounts or Exchange contacts. By secondary accounts, in Android you can add additional gmail accounts to have the mail/contacts synced. The above intent will not list those additional contacts. I am also told that on the HTC Desire you can add contacts to the phone that do not get synced up to Google. These contacts also do not show up. So how do I get a real list of contacts so I can create my own list activity that works properly where the Google intent does not.

  • [NSData dataWithContentsOfFile:path] doesn't work

    - by Felics
    Hello, when I have the fallowing code to read a binary file: NSString* file = [NSString stringWithUTF8String:fileName]; NSString* filePath = resource ? [[NSBundle mainBundle] pathForResource:file ofType:nil] : [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent: file]; NSData* fileData = [NSData dataWithContentsOfFile:filePath]; Where "fileName" and resource are load function parameters. "resource" is used to know if the file is located in application bundle or in Documents. Sometimes this code works well and sometimes it doesn't. As far I saw this problem is random. I can run the code 10 times in a row and it works fine and after that it gives me nil data without any modification. Does anybody knows what could be the problem? Could it be related with file extension or file name? Thank you. PS: I use this code on iPhone Simulator and the file exists in application bundle.

  • Referencing java resource files for cold fusion

    - by Chimeara
    I am using a .Jar file containing a .properties file in my CF code, however it seems unable to find the .properties file when run from CF. My java code is: String key =""; String value =""; try { File file = new File("src/test.properties"); FileInputStream fileInput = new FileInputStream(file); Properties properties = new Properties(); properties.load(fileInput); fileInput.close(); Enumeration enuKeys = properties.keys(); while (enuKeys.hasMoreElements()) { key = (String) enuKeys.nextElement(); value = properties.getProperty(key); //System.out.println(key + ": " + value); } } catch (FileNotFoundException e) { e.printStackTrace(); key ="error"; } catch (IOException e) { e.printStackTrace(); key ="error"; } return(key + ": " + value); I have my test.properties file in the project src folder, and make sure it is selected when compiling, when run from eclipse it gives the expected key and value, however when run from CF I get the caught errors. My CF code is simply: propTest = CreateObject("java","package.class"); testResults = propTest.main2(); Is there a special way to reference the .properties file so CF can access it, or do I need to include the file outside the .jar somewhere?

  • Remove items from one list in another

    - by coffeeaddict
    I'm trying to figure out how to traverse a generic list of items that I want to remove from another list of items. So lest say I have this as a hypothetical example List<car> list1 = GetTheList(); List<car> list2 = GetSomeOtherList(); I want to traverse list1 with a foreach and remove each item in List1 in List2. I'm not quite sure how to go about that as foreach is not index based.

  • ToList()-- Does it Create a New List?

    - by Ngu Soon Hui
    Let's say I have a class public class MyObject { public int SimpleInt{get;set;} } And I have a List<MyObject>, and I ToList() it and then change one of the SimpleInt, will my change be propagated back to the original list. In other words, what would be the output of the following method? public void RunChangeList() { var objs = new List<MyObject>(){new MyObject(){SimpleInt=0}}; var whatInt = ChangeToList(objs ); } public int ChangeToList(List<MyObject> objects) { var objectList = objects.ToList(); objectList[0].SimpleInt=5; return objects[0].SimpleInt; } Why? P/S: I'm sorry if it seems obvious to find out. But I don't have compiler with me now...
