  • vb.net Object Initialiser List(Of T)

    - by Tim B James
    I have been looking at some C# code: List<Employee> Employees = new List<Employee>{ new Employee{firstname="Aamir",lastname="Hasan",age=20}, new Employee{firstname="awais",lastname="Hasan",age=50}, new Employee{firstname="Bill",lastname="Hasan",age=70}, new Employee{firstname="sobia",lastname="khan",age=80}, }; Now when I convert this to vb.net Dim Employees as List(Of Employee) = New List(Of Employee)() With { New Employee() With { _ .firstname = "Aamir", _ .lastname = "Hasan", _ .age = 20 _ }, _ New Employee() With { _ .firstname = "awais", _ .lastname = "Hasan", _ .age = 50 _ }, _ New Employee() With { _ .firstname = "Bill", _ .lastname = "Hasan", _ .age = 70 _ }, _ New Employee() With { _ .firstname = "sobia", _ .lastname = "khan", _ .age = 80 _ } _ } I get the error "Name of field or property being initialized in an object initializer must start with'.'." Now I can get an array of employee using the code: Dim Employees = { New Employee() With { _ .FirstName = "Aamir", _ .LastName = "Hasan", _ .Age = 20}, _ New Employee() With { _ .FirstName = "Awais", _ .LastName = "Hasan", _ .Age = 50}, _ New Employee() With { _ .FirstName = "Bill", _ .LastName = "Hasan", _ .Age = 70 _ } _ } But I would like a List(Of Employee) as it is bugging me as to why this doesnt work in vb.net?

  • How to randomize a sorted list?

    - by Faken
    Here's a strange question for you guys, I have a nice sorted list that I wish to randomize. How would i go about doing that? In my application, i have a function that returns a list of points that describe the outline of a discretized object. Due to the way the problem is solved, the function returns a nice ordered list. i have a second boundary described in math and want to determine if the two objects intersect each other. I simply itterate over the points and determine if any one point is inside the mathematical boundary. The method works well but i want to increase speed by randomizing the point data. Since it is likely that that my mathematical boundary will be overlapped by a series of points that are right beside each other, i think it would make sense to check a randomized list rather than iterating over a nice sorted one (as it only takes a single hit to declare an intersection). So, any ideas on how i would go about randomizing an ordered list?

    Is there a software that can detect and list previously installed programs on a computer? Or any method you know which I can use so that I could see what programs were previously installed assuming that those programs were only uninstalled using the add/remove programs in control panel. Or if you know a method which will also detect and list previously installed programs which are uninstalled using advanced uninstaller like revo.

    Suppose a HTML markup like this: <ul> <li>List item 1</li> <li>List item 2</li> <li>List item 3</li><!-- I want to select only this --> </ul> Would it be possible to select only the third list item in the unordered list element? I've been browsing the jQuery documentation but I can't find any selector that could do this.

  • How do I hide data/field in a List in J2ME

    - by pi
    Hi, I am working on a J2ME app which has dynamically generated Lists. Items on this list may be consequently selected, and the selection processed within the commandAction block. Is there a way to have the IDs of variables populating the List (from a remote database) included in the List item definition as in: this.append("A", null); this.append("B", null); or: String[] arrayOfValues = {"A", "B"}; new List("Menu", List.IMPLICIT, arrayOfValues, null); such that when an item is selected, perhaps A, I can also have its database ID for perhaps further processing. Is it possible to hide a field/data? Thanks.

  • jQuery-AJAX to rebind dropdown list to results from stored procedure

    - by webworm
    I have a dropdown list of peoples names that is quite long. As many as 2,000 names. I would like to make it easier to find the name the user is interested in by limiting the dropdown list to a subset of names at a time. I have done this by creating a series of 26 links (A, B, C ... Z) that call a method in the code behind that populates the dropdown list with only those names starting with the letter the user clicked. This all works well but I would like to be able to use AJAX to accomplish this update of the dropdown list without a page refresh. I would like to use jQuery for the AJAX functionality rather than ASP.NET AJAX. My problem is I am not sure how to execute the stored procedure and then "rebind" the dropdown list with the new dataset via jQuery AJAX. Any suggestions or resources that might provide and example or walk-through? Thank you.

  • How do you write multiple lists from Matlab to the same excel file?

    - by Ben Fossen
    I have several lists in Matlab that I want to write to the same excel file. I have one list xordered and another list aspl. I do not know the length of the lists till after I run the Matlab program. I used data = xlswrite('edgar.xls',fliplr(sortedx'),'A2:A3000') for the first list but when I tried to write another list to the same file like this I ended up with two different excel files named edgar.xls asp_data = xlswrite('edagr.xls', fliplr(aspl'), 'B2:B3000') Is there a way I can write both of these lists into the same excel file? xordered in the A column and aspl in the B column?

  • Sharepoint: How to obtain the current site/web/list properly

    - by driAn
    Hi all What is the best way to obtain the current site/web/list ? Option 1 - Reusing existing objects SPSite site = SPContext.Current.Site; SPweb web = SPContext.Current.Web; SPList list = SPContext.Current.List; Option 2 - Creating new objects SPSite site = new SPSite(SPContext.Current.Site.ID); // dispose me SPweb web = site.OpenWeb(SPContext.Current.Web.ID); // dispose me SPList list = web.Lists[SPContext.Current.List.ID]; I experienced problems when using option 1 in some situations. Since then I chose the 2nd option and it worked fine so far. What is your opinion on this? I is generally better to go with option 2? Other suggestions?

  • Python - counting sign changes

    - by dadashek
    I have a list of numbers I am reading left to right. Anytime I encounter a sign change when reading the sequence I want to count it. X = [-3,2,7,-4,1,-1,1,6,-1,0,-2,1] X = [-, +, +, -, +, -, +, +, -, -,-,+] So, in this list there are 8 sign changes. When Item [0] (in this case -3) is negative it is considered a sign change. Also, any 0 in the list is considered [-]. Any help would be greatly appreciated.

  • getElementsByTagName returns 0-length list when called from didFinishLoad delegate

    - by Emerick Rogul
    I'm using the Chromium port of WebKit on Windows and I'm trying to retrieve a list of all of the images in my document. I figured the best way to do this was to implement WebKit::WebFrameClient::didFinishLoading like so: WebNodeList list = document->getElementsByTagName(L"img"); for (size_t i = 0; i < list.length(); ++i) { // Manipulate images here... } However, when this delegate fires, list.length() returns 0. The only times I've seen it return a list of non-zero length is when I substitute "body" or "head" for "img". Strangely enough, if I call getElementsByTagName(L"img") outside of the delegate, it works correctly. I'm guessing that the DOM isn't fully loaded when didFinishLoading is called, but that would seem to contradict the delegate's name. Does anyone know what I may be missing here?

  • why it throws index out of bounds exception??

    Hi I want to use merge sort for sorting my doubly linked list.I have created 3 classes(Node,DoublyLinkedList,MergeSort) but it will throw this exception for these lines: 1.in the getNodes method of DoublyLinkedList---> throw new IndexOutOfBoundsException(); 2.in the add method of DoublyLinkedList-----> Node cursor = getNodes(index); 3.in the sort method of MergeSort class------> listTwo.add(x,localDoublyLinkedList.getValue(x)); 4.in the main method of DoublyLinkedList----->merge.sort(); this is my Merge class:(I put the whole code for this class for beter understanding) public class MergeSort { private DoublyLinkedList localDoublyLinkedList; public MergeSort(DoublyLinkedList list) { localDoublyLinkedList = list; } public void sort() { if (localDoublyLinkedList.size() <= 1) { return; } DoublyLinkedList listOne = new DoublyLinkedList(); DoublyLinkedList listTwo = new DoublyLinkedList(); for (int x = 0; x < (localDoublyLinkedList.size() / 2); x++) { listOne.add(x, localDoublyLinkedList.getValue(x)); } for (int x = (localDoublyLinkedList.size() / 2) + 1; x < localDoublyLinkedList.size(); x++) { listTwo.add(x, localDoublyLinkedList.getValue(x)); } //Split the DoublyLinkedList again MergeSort sort1 = new MergeSort(listOne); MergeSort sort2 = new MergeSort(listTwo); sort1.sort(); sort2.sort(); merge(listOne, listTwo); } public void merge(DoublyLinkedList a, DoublyLinkedList b) { int x = 0; int y = 0; int z = 0; while (x < a.size() && y < b.size()) { if (a.getValue(x) < b.getValue(y)) { localDoublyLinkedList.add(z, a.getValue(x)); x++; } else { localDoublyLinkedList.add(z, b.getValue(y)); y++; } z++; } //copy remaining elements to the tail of a[]; for (int i = x; i < a.size(); i++) { localDoublyLinkedList.add(z, a.getValue(i)); z++; } for (int i = y; i < b.size(); i++) { localDoublyLinkedList.add(z, b.getValue(i)); z++; } } } and just a part of my DoublyLinkedList: private Node getNodes(int index) throws IndexOutOfBoundsException { if (index < 0 || index > length) { throw new IndexOutOfBoundsException(); } else { Node cursor = head; for (int i = 0; i < index; i++) { cursor = cursor.getNext(); } return cursor; } } public void add(int index, int value) throws IndexOutOfBoundsException { Node cursor = getNodes(index); Node temp = new Node(value); temp.setPrev(cursor); temp.setNext(cursor.getNext()); cursor.getNext().setPrev(temp); cursor.setNext(temp); length++; } public static void main(String[] args) { int i = 0; i = getRandomNumber(10, 10000); DoublyLinkedList list = new DoublyLinkedList(); for (int j = 0; j < i; j++) { list.add(j, getRandomNumber(10, 10000)); MergeSort merge = new MergeSort(list); merge.sort(); System.out.println(list.getValue(j)); } } PLEASE help me thanks alot.

  • create a dict of lists from a string

    - by Chris Card
    I want to convert a string such as 'a=b,a=c,a=d,b=e' into a dict of lists {'a': ['b', 'c', 'd'], 'b': ['e']} in Python 2.6. My current solution is this: def merge(d1, d2): for k, v in d2.items(): if k in d1: if type(d1[k]) != type(list()): d1[k] = list(d1[k]) d1[k].append(v) else: d1[k] = list(v) return d1 record = 'a=b,a=c,a=d,b=e' print reduce(merge, map(dict,[[x.split('=')] for x in record.split(',')])) which I'm sure is unnecessarily complicated. Any better solutions?

  • Haskell: Pattern Matching with Lists

    - by user1670032
    I'm trying to make a function that takes in a list, and if one of the elements is negative, then any elements in that list that are equal to its positive counterpart should be changed to 0. Eg, if there is a -2 in a list, then all 2's in that list should be changed to 0. Any ideas why it only works for some cases and not others? I'm not understanding why this is, I've looked it over several times. changeToZero [] = [] changeToZero [x] = [x] changeToZero (x:zs:y:ws) | (x < 0) && ((-1)*(x) == y) = x : zs : 0 : changeToZero ws changeToZero (x:xs) = x : changeToZero xs *Main changeToZero [-1,1,-2,2,-3,3] [-1,1,-2,2,-3,3] *Main changeToZero [-2,1,2,3] [-2,1,0,3] *Main changeToZero [-2,1,2,3,2] [-2,1,0,3,2] *Main changeToZero [1,-2,2,2,1] [1,-2,2,0,1]

Create features and elements with MOSS feature builder at Site collection level so scope="site" installed via stsadm activated via UI "went to site collection website", Site Setting Site collection Feature (and saw my custom list "MainCatalog") and was able to activate. then went to "mySiteCollection Site Settings Site Libraries and Lists " My list is showing But it shows in the "mySiteCollection Create Custom Lists "MainCatalog" I guess it's showing there as a template... But my intention is to deploy this list from development to test environment. EXTREMELY STRESSED. I AM ON THIS FOR LAST 8 DAYS.....
