  • Themes outside application.

    - by Marek
    Hi all I read http://forum.kohanaframework.org/comments.php?DiscussionID=5744&page=1#Item_0 and I want to use similar solution, but with db. In my site controller after(): $theme = $page->get_theme_name(); //Orange Kohana::set_module_path('themes', Kohana::get_module_path('themes').'/'.$theme); $this->template = View::factory('layout') I checked with firebug: fire::log(Kohana::get_module_path('themes')); // D:\tools\xampp\htdocs\kohana\themes/Orange I am sure that path exists. I have directly in 'Orange' folder 'views' folder with layout.php file. But I am getting: The requested view layout could not be found Extended Kohana_Core is just: public static function get_module_path($module_key) { return self::$_modules[$module_key]; } public static function set_module_path($module_key, $path) { self::$_modules[$module_key] = $path; } Could anybody help me with solving that issue? Maybe it is a .htaccess problem: # Turn on URL rewriting RewriteEngine On # Put your installation directory here: # If your URL is www.example.com/kohana/, use /kohana/ # If your URL is www.example.com/, use / RewriteBase /kohana/ # Protect application and system files from being viewed RewriteCond $1 ^(application|system|modules) # Rewrite to index.php/access_denied/URL RewriteRule ^(.*)$ / [PT,L] RewriteRule ^(media) - [PT,L] RewriteRule ^(themes) - [PT,L] # Allow these directories and files to be displayed directly: # - index.php (DO NOT FORGET THIS!) # - robots.txt # - favicon.ico # - Any file inside of the images/, js/, or css/ directories RewriteCond $1 ^(index\.php|robots\.txt|favicon\.ico|static) # No rewriting RewriteRule ^(.*)$ - [PT,L] # Rewrite all other URLs to index.php/URL RewriteRule ^(.*)$ index.php/$1 [PT,L] Could somebody help? What I am doing wrong?

  • Getting an invalidoperationexception when deserialising XML

    - by Paul Johnson
    Hi, I'm writing a simple proof of concept application to load up an XML file and depending on the very simple code, create a window and put something into it (it's for a much larger project). Due to limitations in Mono, I'm having to run in this way. The code I currently have looks like this using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Windows.Forms; using System.IO; using System.Collections; using System.Xml; using System.Xml.Serialization; namespace form_from_xml { public class xmlhandler : Form { public void loaddesign() { FormData f; f = null; try { string path_env = Path.GetDirectoryName(Application.ExecutablePath) + Path.DirectorySeparatorChar; // code dies on the line below XmlSerializer s = new XmlSerializer(typeof(FormData)); TextReader r = new StreamReader(path_env + "designer-test.xml"); f = (FormData)s.Deserialize(r); r.Close(); } catch (System.IO.FileNotFoundException) { MessageBox.Show("Unable to find the form file", "File not found", MessageBoxButtons.OK); } } } [XmlRoot("Forms")] public class FormData { private ArrayList formData; public FormData() { formData = new ArrayList(); } [XmlElement("Element")] public Elements[] elements { get { Elements[] elements = new Elements[formData.Count]; formData.CopyTo(elements); return elements; } set { if (value == null) return; Elements[] elements = (Elements[])value; formData.Clear(); foreach (Elements element in elements) formData.Add(element); } } public int AddItem(Elements element) { return formData.Add(element); } } public class Elements { [XmlAttribute("formname")] public string name; [XmlAttribute("winxsize")] public int winxs; [XmlAttribute("winysize")] public int winys; [XmlAttribute("type")] public object type; [XmlAttribute("xpos")] public int xpos; [XmlAttribute("ypos")] public int ypos; [XmlAttribute("externaldata")] public bool external; [XmlAttribute("externalplace")] public string externalplace; [XmlAttribute("text")] public string text; [XmlAttribute("questions")] public bool questions; [XmlAttribute("questiontype")] public object qtype; [XmlAttribute("numberqs")] public int numberqs; [XmlAttribute("answerfile")] public string ansfile; [XmlAttribute("backlink")] public int backlink; [XmlAttribute("forwardlink")] public int forwardlink; public Elements() { } public Elements(string fn, int wx, int wy, object t, int x, int y, bool ext, string extpl, string te, bool q, object qt, int num, string ans, int back, int end) { name = fn; winxs = wx; winys = wy; type = t; xpos = x; ypos = y; external = ext; externalplace = extpl; text = te; questions = q; qtype = qt; numberqs = num; ansfile = ans; backlink = back; forwardlink = end; } } } With a very simple xmlhandler xml = new xmlhander(); xml.loaddesign(); attached to a winform button. Everything is in the same namespace and the xml file actually exists. This is annoying me now - can anyone spot the error of my ways? Paul

  • Are free operator->* overloads evil?

    - by Potatoswatter
    I was perusing section 13.5 after refuting the notion that built-in operators do not participate in overload resolution, and noticed that there is no section on operator->*. It is just a generic binary operator. Its brethren, operator->, operator*, and operator[], are all required to be non-static member functions. This precludes definition of a free function overload to an operator commonly used to obtain a reference from an object. But the uncommon operator->* is left out. In particular, operator[] has many similarities. It is binary (they missed a golden opportunity to make it n-ary), and it accepts some kind of container on the left and some kind of locator on the right. Its special-rules section, 13.5.5, doesn't seem to have any actual effect except to outlaw free functions. (And that restriction even precludes support for commutativity!) So, for example, this is perfectly legal (in C++0x, remove obvious stuff to translate to C++03): #include <utility> #include <iostream> #include <type_traits> using namespace std; template< class F, class S > typename common_type< F,S >::type operator->*( pair<F,S> const &l, bool r ) { return r? l.second : l.first; } template< class T > T & operator->*( pair<T,T> &l, bool r ) { return r? l.second : l.first; } template< class T > T & operator->*( bool l, pair<T,T> &r ) { return l? r.second : r.first; } int main() { auto x = make_pair( 1, 2.3 ); cerr << x->*false << " " << x->*4 << endl; auto y = make_pair( 5, 6 ); y->*(0) = 7; y->*0->*y = 8; // evaluates to 7->*y = y.second cerr << y.first << " " << y.second << endl; } I can certainly imagine myself giving into temp[la]tation. For example, scaled indexes for vector: v->*matrix_width[2][5] = x; Did the standards committee forget to prevent this, was it considered too ugly to bother, or are there real-world use cases?

  • Android: How/where to put gesture code into IME?

    - by CardinalFIB
    Hi, I'm new to Android but I'm trying to create an IME that allows for gesture-character recognition. I can already do simple apps that perform gesture recognition but am not sure where to hook in the gesture views/obj with an IME. Here is a starting skeleton of what I have for the IME so far. I would like to use android.gesture.Gesture/Prediction/GestureOverlayView/OnGesturePerformedListener. Does anyone have advice? -- CardinalFIB gestureIME.java public class gestureIME extends InputMethodService { private static Keyboard keyboard; private static KeyboardView kView; private int lastDisplayWidth; @Override public void onCreate() { super.onCreate(); } @Override public void onInitializeInterface() { int displayWidth; if (keyboard != null) { displayWidth = getMaxWidth(); if (displayWidth == lastDisplayWidth) return; else lastDisplayWidth = getMaxWidth(); } keyboard = new GestureKeyboard(this, R.xml.keyboard); } @Override public View onCreateInputView() { kView = (KeyboardView) getLayoutInflater().inflate(R.layout.input, null); kView.setOnKeyboardActionListener(kListener); kView.setKeyboard(keyboard); return kView; } @Override public View onCreateCandidatesView() { return null; } @Override public void onStartInputView(EditorInfo attribute, boolean restarting) { super.onStartInputView(attribute, restarting); kView.setKeyboard(keyboard); kView.closing(); //what does this do??? } @Override public void onStartInput(EditorInfo attribute, boolean restarting) { super.onStartInput(attribute, restarting); } @Override public void onFinishInput() { super.onFinishInput(); } public KeyboardView.OnKeyboardActionListener kListener = new KeyboardView.OnKeyboardActionListener() { @Override public void onKey(int keyCode, int[] otherKeyCodes) { if(keyCode==Keyboard.KEYCODE_CANCEL) handleClose(); if(keyCode==10) getCurrentInputConnection().commitText(String.valueOf((char) keyCode), 1); //keyCode RETURN } @Override public void onPress(int primaryCode) {} // TODO Auto-generated method stub @Override public void onRelease(int primaryCode) {} // TODO Auto-generated method stub @Override public void onText(CharSequence text) {} // TODO Auto-generated method stub @Override public void swipeDown() {} // TODO Auto-generated method stub @Override public void swipeLeft() {} // TODO Auto-generated method stub @Override public void swipeRight() {} // TODO Auto-generated method stub @Override public void swipeUp() {} // TODO Auto-generated method stub }; private void handleClose() { requestHideSelf(0); kView.closing(); } } GestureKeyboard.java package com.android.jt.gestureIME; import android.content.Context; import android.inputmethodservice.Keyboard; public class GestureKeyboard extends Keyboard { public GestureKeyboard(Context context, int xmlLayoutResId) { super(context, xmlLayoutResId); } } GesureKeyboardView.java package com.android.jt.gestureIME; import android.content.Context; import android.inputmethodservice.KeyboardView; import android.inputmethodservice.Keyboard.Key; import android.util.AttributeSet; public class GestureKeyboardView extends KeyboardView { public GestureKeyboardView(Context context, AttributeSet attrs) { super(context, attrs); } public GestureKeyboardView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected boolean onLongPress(Key key) { return super.onLongPress(key); } } keyboard.xml <?xml version="1.0" encoding="utf-8"?> <Keyboard xmlns:android="http://schemas.android.com/apk/res/android" android:keyWidth="10%p" android:horizontalGap="0px" android:verticalGap="0px" android:keyHeight="@dimen/key_height" > <Row android:rowEdgeFlags="bottom"> <Key android:codes="-3" android:keyLabel="Close" android:keyWidth="20%p" android:keyEdgeFlags="left"/> <Key android:codes="10" android:keyLabel="Return" android:keyWidth="20%p" android:keyEdgeFlags="right"/> </Row> </Keyboard> input.xml <?xml version="1.0" encoding="utf-8"?> <com.android.jt.gestureIME.GestureKeyboardView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gkeyboard" android:layout_alignParentBottom="true" android:layout_width="fill_parent" android:layout_height="wrap_content" />

  • FullCalendar displaying last weeks events below this weeks events

    - by Brian
    I am developing an application to manage an On-Call calendar, using FullCalendar to render it. Most events are 1 week long, starting at 8:00 AM Tuesday and ending the following Tuesday at 8:00 AM. Another event, presumably with a different person on-call, will follow that event. During a hallway usability test, someone commented that the month calendar view was difficult to read because the previous weeks event is not at the top of the stack, instead rendering below the event that starts during that week. When being viewed, the eye perceives that it should go down 1 line to view the remaining timeline because the event from last week is there, instead of moving down to the following week. I investigated what I believe to be the problem: function segCmp(a, b) { return (b.msLength - a.msLength) * 100 + (a.event.start - b.event.start); } sorts the events for a row, but uses the length of the event in the calculation. Since the current week's event will have a longer duration, it always get sorted to the top. To test, I changed the start dates to Wednesday so the durations are closer. This cause the events to render how I would expect, with last weeks events at the top and this weeks at the bottom. I thought that if one of the events in the compare doesn't start that week, then it should only be compared based on the start times. I modified the function to be: function segCmp(a, b) { if (a.isStart == false || b.isStart == false) { return (a.event.start - b.event.start); } return (b.msLength - a.msLength) * 100 + (a.event.start - b.event.start); } This solved my problem, and the rendering now looks good - and passes the hallway test. What I don't know is if this would have an impact in other areas. I have taken a look at the other views (month, week, day) and they all seem to be rendering properly as well. I am just not familiar with FullCalendar enough to file a bug or feature request on this, or if this would even be considered a bug. I am wondering if what I modified is correct, or if it is not what a better modification would be to fix this issue. Thanks! Below I have the json results for what should be displayed: [{"title":"Person 1 - OnCall (OSS On Call)","id":12,"allDay":false,"start":"2010-11-30T15:00:00.0000000Z","end":"2010-12-07T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/12"}, {"title":"Person 2 - OnCall (OSS On Call)","id":13,"allDay":false,"start":"2010-12-07T15:00:00.0000000Z","end":"2010-12-14T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/13"}, {"title":"Person 3 - OnCall (OSS On Call)","id":14,"allDay":false,"start":"2010-12-14T15:00:00.0000000Z","end":"2010-12-21T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/14"}, {"title":"Person 4 - OnCall (OSS On Call)","id":15,"allDay":false,"start":"2010-12-21T15:00:00.0000000Z","end":"2010-12-28T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/15"}, {"title":"Person 5 - OnCall (OSS On Call)","id":16,"allDay":false,"start":"2010-12-28T15:00:00.0000000Z","end":"2011-01-04T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/16"}, {"title":"Person 6 - OnCall (OSS On Call)","id":17,"allDay":false,"start":"2011-01-04T15:00:00.0000000Z","end":"2011-01-11T15:00:00.0000000Z","editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/17"}, {"title":"Christmas","id":2,"allDay":true,"start":"2010-12-25T07:00:00.0000000Z","end":null,"editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/2"}, {"title":"New Years Eve","id":3,"allDay":true,"start":"2010-12-31T07:00:00.0000000Z","end":null,"editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/3"}, {"title":"New Years Day","id":4,"allDay":true,"start":"2011-01-01T07:00:00.0000000Z","end":null,"editable":false,"className":"fc-event-title-calendar","url":"/TimeManagement/Edit/4"}]

  • Dynamically specify the type in C#

    - by Lirik
    I'm creating a custom DataSet and I'm under some constrains: I want the user to specify the type of the data which they want to store. I want to reduce type-casting because I think it will be VERY expensive. I will use the data VERY frequently in my application. I don't know what type of data will be stored in the DataSet, so my initial idea was to make it a List of objects, but I suspect that the frequent use of the data and the need to type-cast will be very expensive. The basic idea is this: class DataSet : IDataSet { private Dictionary<string, List<Object>> _data; /// <summary> /// Constructs the data set given the user-specified labels. /// </summary> /// <param name="labels"> /// The labels of each column in the data set. /// </param> public DataSet(List<string> labels) { _data = new Dictionary<string, List<object>>(); foreach (string label in labels) { _data.Add(label, new List<object>()); } } #region IDataSet Members public List<string> DataLabels { get { return _data.Keys.ToList(); } } public int Count { get { _data[_data.Keys[0]].Count; } } public List<object> GetValues(string label) { return _data[label]; } public object GetValue(string label, int index) { return _data[label][index]; } public void InsertValue(string label, object value) { _data[label].Insert(0, value); } public void AddValue(string label, object value) { _data[label].Add(value); } #endregion } A concrete example where the DataSet will be used is to store data obtained from a CSV file where the first column contains the labels. When the data is being loaded from the CSV file I'd like to specify the type rather than casting to object. The data could contain columns such as dates, numbers, strings, etc. Here is what it could look like: "Date","Song","Rating","AvgRating","User" "02/03/2010","Code Monkey",4.6,4.1,"joe" "05/27/2009","Code Monkey",1.2,4.5,"jill" The data will be used in a Machine Learning/Artificial Intelligence algorithm, so it is essential that I make the reading of data very fast. I want to eliminate type-casting as much as possible, since I can't afford to cast from 'object' to whatever data type is needed on every read. I've seen applications that allow the user to pick the specific data type for each item in the csv file, so I'm trying to make a similar solution where a different type can be specified for each column. I want to create a generic solution so I don't have to return a List<object> but a List<DateTime> (if it's a DateTime column) or List<double> (if it's a column of doubles). Is there any way that this can be achieved? Perhaps my approach is wrong, is there a better approach to this problem?

  • In ASP.NET MVC, How do I make a partial view available to all controllers?

    - by Quakkels
    In ASP.NET MVC, How do I make a partial view available to all controllers? I want to create navigation that is common across the entire site, but when I place the Html.Action into my master page, it only works on views associated with 1 controller. Right now, I have a controller action defined like this: // GET: GetCategoriesPartial [ChildActionOnly] public ActionResult GetCategoriesPartial() { var category = CategoriesDataContext.GetCategories(); return PartialView(category); } And I've created my partial view like this: <%@ Import Namespace="wopr.Models" %> <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <ul> <% foreach (var cat in Model as IEnumerable<Category>) { %> <li><a href="/categories/Details/<%=cat.catID%>"><%=cat.catName%></a></li> <% } %> </ul> My Master Page looks like this: <%@ Import Namespace="wopr.Models" %> <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title> <link type="text/css" rel="Stylesheet" href="/Content/Site.css" /> </head> <body> <div class="wrap-all"> <div style="text-align:right;"> <a href="/">Home</a> | <a href="/games/">Games</a> | <a href="/games/Index2/1">Games <em>(paginated)</em></a> | <a href="/categories/">Categories</a> | <a href="/upload/">Upload</a> </div> <asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder> <!--This errors on any non-CategoryController page.--> <%= Html.Action("GetCategoriesPartial")%> <!----> </div> </body> </html> This code works as long as I'm viewing something handled by the CategoriesController. If I go to any view handled by a different controller, I get the exception: System.Web.HttpException: A public action method 'GetCategoriesPartial' was not found on controller 'wopr.Controllers.GamesController'. How do I make this partial view available to all the site's controllers? Thanks for any help. Quakkels

  • "Attach or Add an entity that is not new...loaded from another DataContext. This is not supported."

    - by sah302
    Similar error as other questions, but not quite the same, I am not trying to attach anything. What I am trying to do is insert a new row into a linking table, specifically UserAccomplishment. Relations are set in LINQ to User and Accomplishment Tables. I have a generic insert function: Public Function insertRow(ByVal entity As ImplementationType) As Boolean If entity IsNot Nothing Then Dim lcfdatacontext As New LCFDataContext() Try lcfdatacontext.GetTable(Of ImplementationType)().InsertOnSubmit(entity) lcfdatacontext.SubmitChanges() lcfdatacontext.Dispose() Return True Catch ex As Exception Return False End Try Else Return False End If End Function If you try and give UserAccomplishment the two appropriate objects this will naturally crap out if either the User or Accomplishment already exist. It only works when both user and accomplishment don't exist. I expected this behavior. What does work is simply giving the userAccomplishment object a user.id and accomplishment.id and populating the rest of the fields. This works but is kind of awkward to use in my app, it would be much easier to simply pass in both objects and have it work out what already exists and what doesn't. Okay so I made the following (please ignore the fact that this is horribly inefficient because I know it is): Public Class UserAccomplishmentDao Inherits EntityDao(Of UserAccomplishment) Public Function insertLinkerObjectRow(ByVal userAccomplishment As UserAccomplishment) Dim insertSuccess As Boolean = False If Not userAccomplishment Is Nothing Then Dim userDao As New UserDao() Dim accomplishmentDao As New AccomplishmentDao() Dim user As New User() Dim accomplishment As New Accomplishment() 'see if either object already exists in db' user = userDao.getOneByValueOfProperty("Id", userAccomplishment.User.Id) accomplishment = accomplishmentDao.getOneByValueOfProperty("Id", userAccomplishment.Accomplishment.Id) If user Is Nothing And accomplishment Is Nothing Then 'neither the user or the accomplishment exist, both are new so insert them both, typical insert' insertSuccess = Me.insertRow(userAccomplishment) ElseIf user Is Nothing And Not accomplishment Is Nothing Then 'user is new, accomplishment is not new, so just insert the user, and the relation in userAccomplishment' Dim userWithExistingAccomplishment As New UserAccomplishment(userAccomplishment.User, userAccomplishment.Accomplishment.Id, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(userWithExistingAccomplishment) ElseIf Not user Is Nothing And accomplishment Is Nothing Then 'user is not new, accomplishment is new, so just insert the accomplishment, and the relation in userAccomplishment' Dim existingUserWithAccomplishment As New UserAccomplishment(userAccomplishment.UserId, userAccomplishment.Accomplishment, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(existingUserWithAccomplishment) Else 'both are not new, just add the relation' Dim userAccomplishmentBothExist As New UserAccomplishment(userAccomplishment.User.Id, userAccomplishment.Accomplishment.Id, userAccomplishment.LastUpdatedBy) insertSuccess = Me.insertRow(userAccomplishmentBothExist) End If End If Return insertSuccess End Function End Class Alright, here I basically check if the supplied user and accomplishment already exists in the db, and if so call an appropriate constructor that will leave whatever already exists empty, but supply the rest of the information so the insert can succeed. However, upon trying an insert: Dim result As Boolean = Me.userAccomplishmentDao.insertLinkerObjectRow(userAccomplishment) In which the user already exists, but the accomplishment does not (the 99% typical scenario) I get the error: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." I have debugged this multiple times now and am not sure why this is occuring, if either User or Accomplishment exist, I am not including it in the final object to try to insert. So nothing appears to be attempted to be added. Even in debug, upon insert, the object was set to empty. So the accomplishment is new and the user is empty. 1) Why is it still saying that and how can I fix it ..using my current structure 2) Pre-emptive 'use repository pattern answers' - I know this way kind of sucks in general and I should be using the repository pattern. However, I can't use that in the current project because I don't have time to refactor that due to my non existence knowledge of it and time constraints. The usage of the app is going to so small that the inefficient use of datacontext's and what have you won't matter so much. I can refactor it once it's up and running, but for now I just need to 'push through' with my current structure. Edit: I also just tested this when having both already exists, and only insert each object's IDs into the table, that works. So I guess I could manually insert whichever object doesn't exist as a single insert, then put the ids only into the linking table, but I still don't know why when one object exists, and I make it empty, it doens't work.

  • Evidence-Based-Scheduling - are estimations only as accurate as the work-plan they're based on?

    - by Assaf Lavie
    I've been using FogBugz's Evidence Based Scheduling (for the uninitiated, Joel explains) for a while now and there's an inherent problem I can't seem to work around. The system is good at telling me the probability that a given project will be delivered at some date, given the detailed list of tasks that comprise the project. However, it does not take into account the fact that during development additional tasks always pop up. Now, there's the garbage-can approach of creating a generic task/scheduled-item for "last minute hacks" or "integration tasks", or what have you, but that clearly goes against the idea of aggregating the estimates of many small cases. It's often the case that during the development stage of a project you realize that there's a whole area your planning didn't cover, because, well, that's the nature of developing stuff that hasn't been developed before. So now your ~3 month project may very well turn into a 6 month project, but not because your estimations were off (you could be the best estimator in the world, for those task the comprised your initial work plan); rather because you ended up adding a whole bunch of new tasks that weren't there to begin with. EBS doesn't help you with that. It could, theoretically (I guess). It could, perhaps, measure the amount of work you add to a project over time and take that into consideration when estimating the time remaining on a given project. Just a thought. In other words, EBS works on a task basis, but not on a project/release basis - but the latter is what's important. It's what your boss typically cares about - delivery date, not the time it takes to finish each task along the way, and not the time it would have taken, if your planning was perfect. So the question is (yes, there's a question here, don't close it): What's your methodology when it comes to using EBS in FogBugz and how do you solve the problem above, which seems to be a main cause of schedule delays and mispredictions? Edit Some more thoughts after reading a few answers: If it comes down to having to choose which delivery date you're comfortable presenting to your higher-ups by squinting at the delivery-probability graph and choosing 80%, or 95%, or 60% (based on what, exactly?) then we've resorted to plain old buffering/factoring of our estimates. In which case, couldn't we have skipped the meticulous case by case hour-sized estimation effort step? By forcing ourselves to break down tasks that take more than a day into smaller chunks of work haven't we just deluded ourselves into thinking our planning is as tight and thorough as it could be? People may be consistently bad estimators that do not even learn from their past mistakes. In that respect, having an EBS system is certainly better than not having one. But what can we do about the fact that we're not that good in planning as well? I'm not sure it's a problem that can be solved by a similar system. Our estimates are wrong because of tendencies to be overly optimistic/pessimistic about certain tasks, and because of neglect to account for systematic delays (e.g. sick days, major bug crisis) - and usually not because we lack knowledge about the work that needs to be done. Our planning, on the other hand, is often incomplete because we simply don't have enough knowledge in this early stage; and I don't see how an EBS-like system could fill that gap. So we're back to methodology. We need to find a way to accommodate bad or incomplete work plans that's better than voodoo-multiplication.

  • Input string was not in the correct format using int.Parse

    - by JDWebs
    I have recently been making a login 'representation' which is not secure. So before answering, please note I am aware of security risks etc., and this will not be on a live site. Also note I am a beginner :P. For my login representation, I am using LINQ to compare values of a DDL to select a username and a Textbox to enter a password, when a login button is clicked. However, an error is thrown 'Input string was not in the correct format', when using int.Parse. Front End: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Login_Test.aspx.cs" Inherits="Login_Login_Test" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Login Test</title> </head> <body> <form id="LoginTest" runat="server"> <div> <asp:DropDownList ID="DDL_Username" runat="server" Height="20px" DataTextField="txt"> </asp:DropDownList> <br /> <asp:TextBox ID="TB_Password" runat="server" TextMode="Password"></asp:TextBox> <br /> <asp:Button ID="B_Login" runat="server" onclick="B_Login_Click" Text="Login" /> <br /> <asp:Literal ID="LI_Result" runat="server"></asp:Literal> </div> </form> </body> </html> Back End: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Login_Login_Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { Binder(); } } private void Binder() { using (DataClassesDataContext db = new DataClassesDataContext()) { DDL_Username.DataSource = from x in db.DT_Honeys select new { id = x.UsernameID, txt = x.Username }; DDL_Username.DataValueField = "id"; DDL_Username.DataTextField = "txt"; DDL_Username.DataBind(); } } protected void B_Login_Click(object sender, EventArgs e) { if (TB_Password.Text != "") { using (DataClassesDataContext db = new DataClassesDataContext()) { DT_Honey blah = new DT_Honey(); blah = db.DT_Honeys.SingleOrDefault(x => x.UsernameID == int.Parse(DDL_Username.SelectedValue.ToString())); if (blah == null) { LI_Result.Text = "Something went wrong :/"; } if (blah.Password == TB_Password.Text) { LI_Result.Text = "Credentials recognised :-)"; } else { LI_Result.Text = "Error with credentials :-("; } } } } } I am aware this problem is very common, but none of the help I have found online is useful/relevant. Any help/suggestions appreciated; thank you for your time :-).

  • Generics and Performance question.

    - by Tarmon
    Hey Everyone, I was wondering if anyone could look over a class I wrote, I am receiving generic warnings in Eclipse and I am just wondering if it could be cleaned up at all. All of the warnings I received are surrounded in ** in my code below. The class takes a list of strings in the form of (hh:mm AM/PM) and converts them into HourMinute objects in order to find the first time in the list that comes after the current time. I am also curious about if there are more efficient ways to do this. This works fine but the student in me just wants to find out how I could do this better. public class FindTime { private String[] hourMinuteStringArray; public FindTime(String[] hourMinuteStringArray){ this.hourMinuteStringArray = hourMinuteStringArray; } public int findTime(){ HourMinuteList hourMinuteList = convertHMStringArrayToHMArray(hourMinuteStringArray); Calendar calendar = new GregorianCalendar(); int hour = calendar.get(Calendar.HOUR_OF_DAY); int minute = calendar.get(Calendar.MINUTE); HourMinute now = new HourMinute(hour,minute); int nearestTimeIndex = findNearestTimeIndex(hourMinuteList, now); return nearestTimeIndex; } private int findNearestTimeIndex(HourMinuteList hourMinuteList, HourMinute now){ HourMinute current; int position = 0; Iterator<HourMinute> iterator = **hourMinuteList.iterator()**; while(iterator.hasNext()){ current = (HourMinute) iterator.next(); if(now.compareTo(current) == -1){ return position; } position++; } return position; } private static HourMinuteList convertHMStringArrayToHMArray(String[] times){ FindTime s = new FindTime(new String[1]); HourMinuteList list = s.new HourMinuteList(); String[] splitTime = new String[3]; for(String time : times ){ String[] tempFirst = time.split(":"); String[] tempSecond = tempFirst[1].split(" "); splitTime[0] = tempFirst[0]; splitTime[1] = tempSecond[0]; splitTime[2] = tempSecond[1]; int hour = Integer.parseInt(splitTime[0]); int minute = Integer.parseInt(splitTime[1]); HourMinute hm; if(splitTime[2] == "AM"){ hm = s.new HourMinute(hour,minute); } else if((splitTime[2].equals("PM")) && (hour < 12)){ hm = s.new HourMinute(hour + 12,minute); } else{ hm = s.new HourMinute(hour,minute); } **list.add(hm);** } return list; } class **HourMinuteList** extends **ArrayList** implements RandomAccess{ } class HourMinute implements **Comparable** { int hour; int minute; public HourMinute(int hour, int minute) { setHour(hour); setMinute(minute); } int getMinute() { return this.minute; } String getMinuteString(){ if(this.minute < 10){ return "0" + this.minute; }else{ return "" + this.minute; } } int getHour() { return this.hour; } void setHour(int hour) { this.hour = hour; } void setMinute(int minute) { this.minute = minute; } @Override public int compareTo(Object aThat) { if (aThat instanceof HourMinute) { HourMinute that = (HourMinute) aThat; if (this.getHour() == that.getHour()) { if (this.getMinute() > that.getMinute()) { return 1; } else if (this.getMinute() < that.getMinute()) { return -1; } else { return 0; } } else if (this.getHour() > that.getHour()) { return 1; } else if (this.getHour() < that.getHour()) { return -1; } else { return 0; } } return 0; } } If you have any questions let me know.

  • Update to Easy Slider 1.7 made all my JQuery code stop working.

    - by Anders H
    I'm pretty novice as a JQuery user goes. I've got some experience implementing different plugins but would be lost trying to customize my own. I can't share the exact site details with you due to a NDA, so I hope someone can give me a little help. I've got a project due today (Just HTML/CSS/JQuery). It has a lightbox, show/hide login menu and a slider is Easy Slider 1.5. Everything was working together, until I attempted to update to Easy Slider 1.7 (see link on same page, I'm too new to post more than 1 link). When I did so, JQuery stopped working for all the plugins. I've attempted to revert back to the original state, by undoing my work (didn't do much), ad JQuery remains broken. Firebug Error Console shared no errors. I can't find anything in the code no matter how hard I look at it. Can anyone help me troubleshoot this JQuery problem? Delivery is supposed to be tonight for the project.

  • How can I bind events to strongly typed datasets of different types?

    My application contains several forms which consist of a strongly typed datagridview, a strongly typed bindingsource, and a strongly typed table adapter. I am using some code in each form to update the database whenever the user leaves the current row, shifts focus away from the datagrid or the form, or closes the form. This code is the same in each case, so I want to make a subclass of form, from which all of these forms can inherit. But the strongly typed data objects all inherit from component, which doesn't expose the events I want to bind to or the methods I want to invoke. The only way I can see of gaining access to the events is to use: Type(string Name).GetEvent(string EventName).AddEventHandler(object Target,Delegate Handler) Similarly, I want to call the Update method of the strongly typed table adapter, and am using Type(string Name).GetMethod(String name, Type[] params).Invoke(object target, object[] params). It works ok, but it seems very heavy handed. Is there a better way? Here is my code for the main class: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Data; using System.Data.SqlClient; using System.ComponentModel; namespace MyApplication { public class AutoSaveDataGridForm: Form { private DataRow PreviousRow; public Component Adapter { private get; set; } private Component dataGridView; public Component DataGridView { private get { return dataGridView; } set { dataGridView = value; Type t = dataGridView.GetType(); t.GetEvent("Leave").AddEventHandler(dataGridView, new EventHandler(DataGridView_Leave)); } } private Component bindingSource; public Component BindingSource { private get { return bindingSource; } set { bindingSource = value; Type t = bindingSource.GetType(); t.GetEvent("PositionChanged").AddEventHandler(bindingSource, new EventHandler(BindingSource_PositionChanged)); } } protected void Save() { if (PreviousRow != null && PreviousRow.RowState != DataRowState.Unchanged) { Type t = Adapter.GetType(); t.GetMethod("Update", new Type[] { typeof(DataRow[]) }).Invoke(Adapter, new object[] { new DataRow[] { PreviousRow } }); } } private void BindingSource_PositionChanged(object sender, EventArgs e) { BindingSource bindingSource = sender as BindingSource; DataRowView CurrentRowView = bindingSource.Current as DataRowView; DataRow CurrentRow = CurrentRowView.Row; if (PreviousRow != null && PreviousRow != CurrentRow) { Save(); } PreviousRow = CurrentRow; } private void InitializeComponent() { this.SuspendLayout(); // // AutoSaveDataGridForm // this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.AutoSaveDataGridForm_FormClosed); this.Leave += new System.EventHandler(this.AutoSaveDataGridForm_Leave); this.ResumeLayout(false); } private void DataGridView_Leave(object sender, EventArgs e) { Save(); } private void AutoSaveDataGridForm_FormClosed(object sender, FormClosedEventArgs e) { Save(); } private void AutoSaveDataGridForm_Leave(object sender, EventArgs e) { Save(); } } } And here is a (partial) form which implements it: public partial class FileTypesInherited :AutoSaveDataGridForm { public FileTypesInherited() { InitializeComponent(); } private void FileTypesInherited_Load(object sender, EventArgs e) { // TODO: This line of code loads data into the 'sharedFoldersInformationV2DataSet.tblFileTypes' table. You can move, or remove it, as needed. this.tblFileTypesTableAdapter.Fill(this.sharedFoldersInformationV2DataSet.tblFileTypes); this.BindingSource = tblFileTypesBindingSource; this.Adapter = tblFileTypesTableAdapter; this.DataGridView = tblFileTypesDataGridView; } }

  • Problems manipulating strings through a stdcall to a dll

    - by ibiza
    I need to create a C++ dll that will be called from another program through stdcall. What is needed : the caller program will pass an array of string to the dll and the dll should change the string values in the array. The caller program will then continue to work with these string values that came from the dll. I made a simple test project and I am obviously missing something... Here is my test C++ dll : #ifndef _DLL_H_ #define _DLL_H_ #include <string> #include <iostream> struct strStruct { int len; char* string; }; __declspec (dllexport) int __stdcall TestFunction(strStruct* s) { std::cout << "Just got in dll" << std::endl; std::cout << s[0].string << std::endl; //////std::cout << s[1].string << std::endl; /* char str1[] = "foo"; strcpy(s[0].string, str1); s[0].len = 3; char str2[] = "foobar"; strcpy(s[1].string, str2); s[1].len = 6; */ //std::cout << s[0].string << std::endl; //std::cout << s[1].string << std::endl; std::cout << "Getting out of dll" << std::endl; return 1; } #endif and here is a simple C# program that I am using to test my test dll : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; namespace TestStr { class Program { [DllImport("TestStrLib.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)] public static extern int TestFunction(string[] s); static void Main(string[] args) { string[] test = new string[2] { "a1a1a1a1a1", "b2b2b2b2b2" }; Console.WriteLine(test[0]); Console.WriteLine(test[1]); TestFunction(test); Console.WriteLine(test[0]); Console.WriteLine(test[1]); Console.ReadLine(); } } } And here is the output produced : a1a1a1a1a1 b2b2b2b2b2 Just got in dll b2b2b2b2b2 Getting out of dll a1a1a1a1a1 b2b2b2b2b2 I have some questions : 1) Why is it outputting the element in the second position of the array rather than in the first position?? 2) If I uncomment the line commented with ////// in the dll file, the program crashes. Why? 3) Obviously I wanted to do more things in the dll (the parts in /* */) than what it does right now, but I am blocked by the first 2 questions... Thanks for all your help

  • Maven not setting classpath for dependencies properly

    - by Matthew
    OS name: "linux" version: "2.6.32-27-generic" arch: "i386" Family: "unix" Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700) Java version: 1.6.0_20 I am trying to use the mysql dependency in with maven in ubuntu. If I move the "mysql-connector-java-5.1.14.jar" file that maven downloaded into my $JAVA_HOME/jre/lib/ext/ folder, everything is fine when I run the jar. I think I should be able to just specify the dependency in the pom.xml file and maven should take care of setting the classpath for the dependency jars automatically. Is this incorrect?

  • com.sun.org.apache.xerces.internal.dom.DocumentImpl cannot be cast to org.codehaus.plexus.util.xml.X

    - by Random
    Afetr using the Model library (see this) for my Maven pom.xml during this weeks I jumped on this error while attempting to write a ConfiguratonContainer into the pom.xml. The javadoc for Model says: public void setConfiguration(Object configuration) Set the configuration as DOM object. Parameters: configuration - So I made some xml with Document (org.w3c.dom.Document) and the xml parser standar javax library. You know the code (it's through all the net) but I paste it here... DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder parser = factory.newDocumentBuilder(); Document doc =parser.newDocument(); And then you fill the code with Element declaration,a lot of appendChild and such. And tried to make it work. Doesn't seem to do well. First tried using plugin.setConfiguration(doc); But it didn't work. Then I tried Obejct obj = doc; plugin.setConfiguration(obj); But it didn't work. Then I searched the net for answers, and guess... It didn't work. There are like 0 people using this library (maven.model) in all the net. So here am I again, asking the senseis for help. Where is my error? I have downloaded the source code of the library trying to see where is the error, but it seems to be ok (as should).

  • subset in geom_point SOMETIMES returns full dataset, instead of none.

    - by Andreas
    I ask the following in the hope that someone might come up with a generic description about the problem.Basically I have no idea whats wrong with my code. When I run the code below, plot nr. 8 turns out wrong. Specifically the subset in geom_point does not work the way it should. (update: With plot nr. 8 the whole dataset is plottet, instead of only the subset). If somebody can tell me what the problem is, I'll update this post.

  • [C#] Not enough memory or not enough handles?

    - by Nayan
    I am working on a large scale project where a custom (pretty good and robust) framework has been provided and we have to use that for showing up forms and views. There is abstract class StrategyEditor (derived from some class in framework) which is instantiated whenever a new StrategyForm is opened. StrategyForm (a customized window frame) contains StrategyEditor. StrategyEditor contains StrategyTab. StrategyTab contains StrategyCanvas. This is a small portion of the big classes to clarify that there are many objects that will be created if one StrategyForm object is allocated in memory at run-time. My component owns all these classes mentioned above except StrategyForm whose code is not in my control. Now, at run-time, user opens up many strategy objects (which trigger creation of new StrategyForm object.) After creating approx. 44 strategy objects, we see that the USER OBJECT HANDLES (I'll use UOH from here onwards) created by the application reaches to about 20k+, while in registry the default amount for handles is 10k. Read more about User Objects here. Testing on different machines made it clear that the number of strategy objects opened is different for message to pop-up - on one m/c if it is 44, then it can be 40 on another. When we see the message pop-up, it means that the application is going to respond slowly. It gets worse with few more objects and then creation of window frames and subsequent objects fail. We first thought that it was not-enough-memory issue. But then reading more about new in C# helped in understanding that an exception would be thrown if app ran out of memory. This is not a memory issue then, I feel (task manager also showed 1.5GB+ available memory.) M/C specs Core 2 Duo 2GHz+ 4GB RAM 80GB+ free disk space for page file Virtual Memory set: 4000 - 6000 My questions Q1. Does this look like a memory issue and I am wrong that it is not? Q2. Does this point to exhaustion of free UOHs (as I'm thinking) and which is resulting in failure of creation of window handles? Q3. How can we avoid loading up of an StrategyEditor object (beyond a threshold, keeping an eye on the current usage of UOHs)? (we already know how to fetch number of UOHs in use, so don't go there.) Keep in mind that the call to new StrategyForm() is outside the control of my component. Q4. I am bit confused - what are Handles to user objects exactly? Is MSDN talking about any object that we create or only some specific objects like window handles, cursor handles, icon handles? Q5. What exactly cause to use up a UOH? (almost same as Q4) I would be really thankful to anyone who can give me some knowledgeable answers. Thanks much! :)

  • what's wrong with my producer-consumer queue design?

    - by toasteroven
    I'm starting with the C# code example here. I'm trying to adapt it for a couple reasons: 1) in my scenario, all tasks will be put in the queue up-front before consumers will start, and 2) I wanted to abstract the worker into a separate class instead of having raw Thread members within the WorkerQueue class. My queue doesn't seem to dispose of itself though, it just hangs, and when I break in Visual Studio it's stuck on the _th.Join() line for WorkerThread #1. Also, is there a better way to organize this? Something about exposing the WaitOne() and Join() methods seems wrong, but I couldn't think of an appropriate way to let the WorkerThread interact with the queue. Also, an aside - if I call q.Start(#) at the top of the using block, only some of the threads every kick in (e.g. threads 1, 2, and 8 process every task). Why is this? Is it a race condition of some sort, or am I doing something wrong? using System; using System.Collections.Generic; using System.Text; using System.Messaging; using System.Threading; using System.Linq; namespace QueueTest { class Program { static void Main(string[] args) { using (WorkQueue q = new WorkQueue()) { q.Finished += new Action(delegate { Console.WriteLine("All jobs finished"); }); Random r = new Random(); foreach (int i in Enumerable.Range(1, 10)) q.Enqueue(r.Next(100, 500)); Console.WriteLine("All jobs queued"); q.Start(8); } } } class WorkQueue : IDisposable { private Queue _jobs = new Queue(); private int _job_count; private EventWaitHandle _wh = new AutoResetEvent(false); private object _lock = new object(); private List _th; public event Action Finished; public WorkQueue() { } public void Start(int num_threads) { _job_count = _jobs.Count; _th = new List(num_threads); foreach (int i in Enumerable.Range(1, num_threads)) { _th.Add(new WorkerThread(i, this)); _th[_th.Count - 1].JobFinished += new Action(WorkQueue_JobFinished); } } void WorkQueue_JobFinished(int obj) { lock (_lock) { _job_count--; if (_job_count == 0 && Finished != null) Finished(); } } public void Enqueue(int job) { lock (_lock) _jobs.Enqueue(job); _wh.Set(); } public void Dispose() { Enqueue(Int32.MinValue); _th.ForEach(th = th.Join()); _wh.Close(); } public int GetNextJob() { lock (_lock) { if (_jobs.Count 0) return _jobs.Dequeue(); else return Int32.MinValue; } } public void WaitOne() { _wh.WaitOne(); } } class WorkerThread { private Thread _th; private WorkQueue _q; private int _i; public event Action JobFinished; public WorkerThread(int i, WorkQueue q) { _i = i; _q = q; _th = new Thread(DoWork); _th.Start(); } public void Join() { _th.Join(); } private void DoWork() { while (true) { int job = _q.GetNextJob(); if (job != Int32.MinValue) { Console.WriteLine("Thread {0} Got job {1}", _i, job); Thread.Sleep(job * 10); // in reality would to actual work here if (JobFinished != null) JobFinished(job); } else { Console.WriteLine("Thread {0} no job available", _i); _q.WaitOne(); } } } } }

  • Why might a System.String object not cache its hash code?

    - by Dan Tao
    A glance at the source code for string.GetHashCode using Reflector reveals the following (for mscorlib.dll version 4.0): public override unsafe int GetHashCode() { fixed (char* str = ((char*) this)) { char* chPtr = str; int num = 0x15051505; int num2 = num; int* numPtr = (int*) chPtr; for (int i = this.Length; i > 0; i -= 4) { num = (((num << 5) + num) + (num >> 0x1b)) ^ numPtr[0]; if (i <= 2) { break; } num2 = (((num2 << 5) + num2) + (num2 >> 0x1b)) ^ numPtr[1]; numPtr += 2; } return (num + (num2 * 0x5d588b65)); } } Now, I realize that the implementation of GetHashCode is not specified and is implementation-dependent, so the question "is GetHashCode implemented in the form of X or Y?" is not really answerable. I'm just curious about a few things: If Reflector has disassembled the DLL correctly and this is the implementation of GetHashCode (in my environment), am I correct in interpreting this code to indicate that a string object, based on this particular implementation, would not cache its hash code? Assuming the answer is yes, why would this be? It seems to me that the memory cost would be minimal (one more 32-bit integer, a drop in the pond compared to the size of the string itself) whereas the savings would be significant, especially in cases where, e.g., strings are used as keys in a hashtable-based collection like a Dictionary<string, [...]>. And since the string class is immutable, it isn't like the value returned by GetHashCode will ever even change. What could I be missing? UPDATE: In response to Andras Zoltan's closing remark: There's also the point made in Tim's answer(+1 there). If he's right, and I think he is, then there's no guarantee that a string is actually immutable after construction, therefore to cache the result would be wrong. Whoa, whoa there! This is an interesting point to make (and yes it's very true), but I really doubt that this was taken into consideration in the implementation of GetHashCode. The statement "therefore to cache the result would be wrong" implies to me that the framework's attitude regarding strings is "Well, they're supposed to be immutable, but really if developers want to get sneaky they're mutable so we'll treat them as such." This is definitely not how the framework views strings. It fully relies on their immutability in so many ways (interning of string literals, assignment of all zero-length strings to string.Empty, etc.) that, basically, if you mutate a string, you're writing code whose behavior is entirely undefined and unpredictable. I guess my point is that for the author(s) of this implementation to worry, "What if this string instance is modified between calls, even though the class as it is publicly exposed is immutable?" would be like for someone planning a casual outdoor BBQ to think to him-/herself, "What if someone brings an atomic bomb to the party?" Look, if someone brings an atom bomb, party's over.

  • OpenXML sdk Modify a sheet in my Excel document

    - by user465202
    hi! I create an empty template in excel. I would like to open the template and edit the document but I do not know how to change the existing sheet. That's the code: using (SpreadsheetDocument xl = SpreadsheetDocument.Open(filename, true)) { WorkbookPart wbp = xl.WorkbookPart; WorkbookPart workbook = xl.WorkbookPart; // Get the worksheet with the required name. // To be used to match the ID for the required sheet data // because the Sheet class and the SheetData class aren't // linked to each other directly. Sheet s = null; if (wbp.Workbook.Sheets.Elements().Count(nm = nm.Name == sheetName) == 0) { // no such sheet with that name xl.Close(); return; } else { s = (Sheet)wbp.Workbook.Sheets.Elements().Where(nm = nm.Name == sheetName).First(); } WorksheetPart wsp = (WorksheetPart)xl.WorkbookPart.GetPartById(s.Id.Value); Worksheet worksheet = new Worksheet(); SheetData sd = new SheetData(); //SheetData sd = (SheetData)wsp.Worksheet.GetFirstChild(); Stylesheet styleSheet = workbook.WorkbookStylesPart.Stylesheet; //SheetData sheetData = new SheetData(); //build the formatted header style UInt32Value headerFontIndex = util.CreateFont( styleSheet, "Arial", 10, true, System.Drawing.Color.Red); //build the formatted date style UInt32Value dateFontIndex = util.CreateFont( styleSheet, "Arial", 8, true, System.Drawing.Color.Black); //set the background color style UInt32Value headerFillIndex = util.CreateFill( styleSheet, System.Drawing.Color.Black); //create the cell style by combining font/background UInt32Value headerStyleIndex = util.CreateCellFormat( styleSheet, headerFontIndex, headerFillIndex, null); /* * Create a set of basic cell styles for specific formats... * If you are controlling your table then you can simply create the styles you need, * this set of code is still intended to be generic. */ _numberStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(3)); _doubleStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(4)); _dateStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(14)); _textStyleId = util.CreateCellFormat(styleSheet, headerFontIndex, headerFillIndex, null); _percentageStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(9)); util.AddNumber(xl, sheetName, (UInt32)3, "E", "27", _numberStyleId); util.AddNumber(xl, sheetName, (UInt32)3, "F", "3.6", _doubleStyleId); util.AddNumber(xl, sheetName, (UInt32)5, "L", "5", _percentageStyleId); util.AddText(xl, sheetName, (UInt32)5, "M", "Dario", _textStyleId); util.AddDate(xl, sheetName, (UInt32)3, "J", DateTime.Now, _dateStyleId); util.AddImage(xl, sheetName, imagePath, "Smile", "Smile", 30, 30); util.MergeCells(xl, sheetName, "D12", "F12"); //util.DeleteValueCell(spreadsheet, sheetName, "F", (UInt32)8); txtCellText.Text = util.GetCellValue(xl, sheetName, (UInt32)5, "M"); double number = util.GetCellDoubleValue(xl, sheetName, (UInt32)3, "E"); double numberD = util.GetCellDoubleValue(xl, sheetName, (UInt32)3, "F"); DateTime datee = util.GetCellDateTimeValue(xl, sheetName, (UInt32)3, "J"); //txtDoubleCell.Text = util.GetCellValue(spreadsheet, sheetName, (UInt32)3, "P"); txtPercentualeCell.Text = util.GetCellValue(xl, sheetName, (UInt32)5, "L"); string date = util.GetCellValue(xl, sheetName, (UInt32)3, "J"); double dateD = Convert.ToDouble(date); DateTime dateTime = DateTime.FromOADate(dateD); txtDateCell.Text = dateTime.ToShortDateString(); //worksheet.Append(sd); /* Columns columns = new Columns(); columns.Append(util.CreateColumnData(10, 10, 40)); worksheet.Append(columns); */ SheetProtection sheetProtection1 = new SheetProtection() { Sheet = true, Objects = true, Scenarios = true, SelectLockedCells = true, SelectUnlockedCells = true }; worksheet.Append(sheetProtection1); wsp.Worksheet = worksheet; wsp.Worksheet.Save(); xl.WorkbookPart.Workbook.Save(); xl.Close(); thanks!

  • Using inheritance and polymorphism to solve a common game problem

    - by Barry Brown
    I have two classes; let's call them Ogre and Wizard. (All fields are public to make the example easier to type in.) public class Ogre { int weight; int height; int axeLength; } public class Wizard { int age; int IQ; int height; } In each class I can create a method called, say, battle() that will determine who will win if an Ogre meets and Ogre or a Wizard meets a Wizard. Here's an example. If an Ogre meets an Ogre, the heavier one wins. But if the weight is the same, the one with the longer axe wins. public Ogre battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else if (this.axeLength > o.axeLength) return this; else if (this.axeLength < o.axeLength) return o; else return this; // default case } We can make a similar method for Wizards. But what if a Wizard meets an Ogre? We could of course make a method for that, comparing, say, just the heights. public Wizard battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else return this; } And we'd make a similar one for Ogres that meet Wizard. But things get out of hand if we have to add more character types to the program. This is where I get stuck. One obvious solution is to create a Character class with the common traits. Ogre and Wizard inherit from the Character and extend it to include the other traits that define each one. public class Character { int height; public Character battle(Character c) { if (this.height > c.height) return this; else if (this.height < c.height) return c; else return this; } } Is there a better way to organize the classes? I've looked at the strategy pattern and the mediator pattern, but I'm not sure how either of them (if any) could help here. My goal is to reach some kind of common battle method, so that if an Ogre meets an Ogre it uses the Ogre-vs-Ogre battle, but if an Ogre meets a Wizard, it uses a more generic one. Further, what if the characters that meet share no common traits? How can we decide who wins a battle?
