  • Finding occurrences of element before and after the element in Array

    - by user3718040
    I am writing a algorithm, if an array contain 3 does not contain between two 1s. like this int array={5, 2, 10, 3, 15, 1, 2, 2} the above array contain 3, before 3 there is no 1 and after 3 is one 1 it should return True. int array={3,2,18,1,0,3,-11,1,3} in this array after first element of 3 there is two 1 it should return False. I have try following code public class Third { public static void main(String[] args){ int[] array = {1,2,4,3, 1}; for(int i=0;i<array.length;i++) { if(array[i]==3) { for(int j=0;j<array[i];j++) { if(array[j]==1) { System.out.println("I foud One before "+array[j]); }else { break; } System.out.println("yes i found the array:"+array[i]); } for(int z=0;z>array[i];z++) { if(array[z]==1) { System.out.println("I found after 3 is :"+array[z]); } break; } } } } } I am not getting exact result from my above code which i want.

  • Why do I get Error#2036 in flash AS3 and how to solve this?

    - by sydas
    I'm currently building an application in flash in relation to RSS/XML feeds for a project. I'm stuck at the moment because I keep getting this error: Error opening URL 'http://distilleryimage6.instagram.com/.jpg' Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed. I know my string picURL is not functioning properly, but am I missing something that makes it not functional?

  • What else I must do allow my method to handle any type of objects

    - by NewHelpNeeder
    So to allow any type object I must use generics in my code. I have rewrote this method to do so, but then when I create an object, for example Milk, it won't let me pass it to my method. Ether there's something wrong with my generic revision, or Milk object I created is not good. How should I pass my object correctly and add it to linked list? This is a method that causes error when I insert an item: public void insertFirst(T dd) // insert at front of list { Link newLink = new Link(dd); // make new link if( isEmpty() ) // if empty list, last = newLink; // newLink <-- last else first.previous = newLink; // newLink <-- old first newLink.next = first; // newLink --> old first first = newLink; // first --> newLink } This is my class I try to insert into linked list: class Milk { String brand; double size; double price; Milk(String a, double b, double c) { brand = a; size = b; price = c; } } This is test method to insert the data: public static void main(String[] args) { // make a new list DoublyLinkedList theList = new DoublyLinkedList(); // this causes: // The method insertFirst(Comparable) in the type DoublyLinkedList is not applicable for the arguments (Milk) theList.insertFirst(new Milk("brand", 1, 2)); // insert at front theList.displayForward(); // display list forward theList.displayBackward(); // display list backward } // end main() } // end class DoublyLinkedApp Declarations: class Link<T extends Comparable<T>> {} class DoublyLinkedList<T extends Comparable<T>> {}

  • Adobe Air, packaged install fails with my trace routine... how come?

    - by artie scie
    I cobbled together some code from here and there for a trace I like... it generates an error to get a stack trace and picks out the traced routine name, I like that detail in the trace log. Problem: it fails in an installed AIR file. I wonder why? I don't expect it to do anything as is... just, I'd prefer it not cause the program to fail! tx artie enter code here static public function XTRACE( ... traceArgs ):void { try { throw new Error(); // make a stack } catch (e:Error) { var stack:String = e.getStackTrace(); var frames:Array = stack.split("\n"); var myFrame:String = String(frames[2]); myFrame = myFrame.replace("\t", ""); // "at " can be followed by some part of the package // you don't want to see. E.g., if your code is all in // com.foo.bar, you can put "at com.foo.bar." so as not // to crowd the display myFrame = myFrame.substr("at ".length); myFrame = myFrame.substring(0, myFrame.indexOf("[")); var now:Date = new Date(); trace(new Date().toLocaleTimeString() + ":" + myFrame + ": " + traceArgs.join(" ")); } }

  • How do I display a sting, based on which id is set as selected?

    - by Cam
    I'd like to display a text string (to be positioned above ul) depending on which link is set to selected by the chgClass fuction. The ids for each display via an alert right now, but I can't seem to make them appear in "english". I know I can set up an array stating "id=text string" but when I do it seems to break the code I already have... <script type="text/javascript"> var Lst; function CngClass(obj){ if (typeof(obj)=='string') obj=document.getElementById(obj); if (Lst) Lst.className=''; obj.className='selected'; Lst=obj; alert(obj.id); } </script> </head> <body onload="CngClass('POSITION_WITHOUT_NOTIFY')"> <div class="slider"> <ul class="bar"> <li class="deny"><a onclick="CngClass(this);" id="POSITION_NOT_ALLOWED" href="#">Deny</a></li> <li class="askDeny"><a onclick="CngClass(this);" id="NOTIFY_POSITION_IF_GRANTED" href="#">Ask Deny</a></li> <li class="askAllow"><a onclick="CngClass(this);" id="NOTIFY_POSITION_IF_NO_RESPONSE" href="#">Ask Allow</a></li> <li class="notify"><a onclick="CngClass(this);" id="NOTIFY_POSITION" href="#">Notfiy</a></li> <li class="allow"><a onclick="CngClass(this);" id="POSITION_WITHOUT_NOTIFY" href="#">Allow</a></li> </ul> </div> </body> </html>

    I am creating dynamic labels and letting users change attributes of the labes like backcolor and so by sending unicode.

  • Saving image to the existing file throws "A generic error occurred in GDI+" error.

    - by ryan
    i am trying to create a overlapped image using different images,then saving to a particular location. so that i can use generated image(overlapped img) in my telerik reporting. it is important to me to save the overlapped image to the same location with same name. but generating this overlapped image second time throws throws "A generic error occurred in GDI+" error. Please help me with this. It seems i can not override the existing image file. i tried deleting the existing image every time i generate the new one. but its not allowing me deleting the file ,may be it is used by telerik reporting. Here is the image create method which takes the baseimage path, sectionimage path and the reportimage path (this is the target locationenter code here) public static void Creat(List<string> sectionNames, string reportImagePath, string baseImagePath) { var file = Image.FromFile(baseImagePath); Graphics g = Graphics.FromImage(file); foreach (var sectionName in sectionNames) { var image = Image.FromFile(sectionName); g.DrawImage(image, new PointF(0.0F, 0.0F)); } file.Save(reportImagePath, ImageFormat.Png); file.Dispose(); }

  • Strange DataTable behaviour

    - by DocSnuggles
    There´s a strange behaviour in my code which I can´t explain... I have worked arround it but I´d like to know the reason of this behaviour. My Code: If dataset.Tables.Count > 0 Then Dim rows() As DataRow = dataset.Tables(0).Select("FileID = " + fileid.ToString) For Each row As DataRow In rows... the one and only table in dataset is: 18 1 1 testpara42 19 1 2 Para2 23 2 1 Para1 24 2 2 Para42 Where the colums are: ParamID - FileID - ParaPos - Paravalue. I want do filter it so that the only rows I get are the ones with the correct fileid... the result when the selection string is "FileID = 1" is an array with 2 rows... everything is fine... but the filter string "FileID = 2" will return 0 Rows... A filter like "FileID < 1" returns 2 Rows correctly. I really cant´t explain this od behaviour, maybe one of the community does. The Table does have more entries but the Filter string just works with the "FileID = 1" selection. Excuse my bad english. Please explain my mistake to me.

  • MongoDB search in C#

    - by user3684208
    I have a problem with querying MongoDB. In my code I have a method Get which has as a parametar a Dictionary. It should go through the database and query it, comparing string and then object. So, i always get a problem with this object part, QueryDocument won't take in an object type because it isn't an BsonValue. I have tried to cast it but it won't work. Do you have any suggestions ? Thanks Code part : public List<ExceptionViewModel> Get(Dictionary<string, object> FilteredExceptions) { MongoClient mongo = new MongoClient(); MongoServer mongoServer = mongo.GetServer(); MongoDatabase db = mongoServer.GetDatabase("Aplikacija"); MongoCollection collection = db.GetCollection("Exceptions"); List<ExceptionViewModel> Get = new List<ExceptionViewModel>(); foreach (KeyValuePair<string,object> item in FilteredExceptions) { var query = new QueryDocument(item.Key.ToString(),item.Value); foreach (ExceptionViewModel exception in collection.FindAs<ExceptionViewModel>(query)) { Console.WriteLine("{0}", exception.BrowserName); } } return Get; }

  • Creating a Simple C# Wrapper to clean up code

    I have this code: public void Contacts(string domainToBeTested, string[] browserList, string timeOut, int numberOfBrowsers) { verificationErrors = new StringBuilder(); for (int i = 0; i < numberOfBrowsers; i++) { ISelenium selenium = new DefaultSelenium("LMTS10", 4444, browserList[i], domainToBeTested); try { selenium.Start(); selenium.Open(domainToBeTested); selenium.Click("link=Email"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-2']/p/a/strong")); selenium.Click("link=Address"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-3']/p/strong")); selenium.Click("link=Telephone"); Assert.IsTrue(selenium.IsElementPresent("//div[@id='tabs-1']/ul/li/strong")); } catch (AssertionException e) { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } finally { selenium.Stop(); } } Assert.AreEqual("", verificationErrors.ToString(), verificationErrors.ToString()); } My problem is i would like to make it so that i can use the code surrounding the 'try' many many times in the rest of the code. I think it has something to do with wrappers, but i can't get a simple answer for this from the web. So in simple terms the only piece of this code which changes is the bit between the try {} the rest is standard code that i have currently used over 100 times and is turning out to be a pain to maintain. Hope this is clear, many thanks.

  • Code casing question for private class fields

    - by user200295
    Take the following example public class Class1{ public string Prop1{ get {return m_Prop1;} set {m_Prop1 = value; } } private string m_Prop1; // this is standard private property variable name // how do we cap this variable name? While the compiler can figure out same casing // it makes it hard to read private Class2 Class2; // we camel case the parameter public Class1(Class2 class2){ this.Class2 = class2; } } Here are my stock rules The class name is capitalized (Class1) The public properties are capitalized (Prop1) The private field tied to a public property has m_ to indicate this. My coworker prefers _ There is some debate if using m_ or _ should be used at all, as it is like Hungarian notation. Private class fields are capitalized. The part I am trying to figure out is what do I do if when the Class name of a private field matches the private field name. For example, private Class2 Class2; This is confusing. If the private field name is not the same class, for example private string Name; , there isn't much issue. Or am I thinking about the issue wrong. Should my classes and private fields be named in such a way that they don't collide?

  • fluent nhibernate - storing and retrieving three classes in/from one table

    - by Will I Am
    Noob question. I have this situation where I have these objects: class Address { string Street; string City; ... } class User { string UserID; Address BillingAddress; Address MailingAddress; ... } What is the proper way of storing this data using (fluent) nHibernate? I could use a separate Address table and create a reference, but they are 1:1 relationships so I don't really want to incur the overhead of a join. Ideally I would store this as a single flat record. So, my question is, what is the proper way of storing an instance of class 'User' in such a way that it stores its contents and also the two addresses as a single record? My knowledge is failing me on how I can store this information in such a way that the two Address records get different column names (e.g. BillingAddress_Street and MailingAddress_Street, for example), and also how to read a record back into a User instance.

  • Java - A better to run code for a period of time

    - by mhollander38
    I need to run some code for a predefined length of time, when the time is up it needs to stop. Currently I am using a TimerTask to allow the code to execute for a set amount of time but this is causing endless threads to be created by the code and is just simply not efficient. Is there a better alternative? Current code; // Calculate the new lines to draw Timer timer3 = new Timer(); timer3.schedule(new TimerTask(){ public void run(){ ArrayList<String> Coords = new ArrayList<String>(); int x = Float.valueOf(lastFour[0]).intValue(); int y = Float.valueOf(lastFour[1]).intValue(); int x1 = Float.valueOf(lastFour[2]).intValue(); int y1 = Float.valueOf(lastFour[3]).intValue(); //Could be the wrong way round (x1,y1,x,y)? Coords = CoordFiller.coordFillCalc(x, y, x1, y1); String newCoOrds = ""; for (int j = 0; j < Coords.size(); j++) { newCoOrds += Coords.get(j) + " "; } newCoOrds.trim(); ClientStorage.storeAmmendedMotion(newCoOrds); } } ,time);

  • How to handle ids and polymorphic associations in views if compound keys are not supported?

    - by duncan
    I have a Movie plan table: movie_plans (id, description) Each plan has items, which describe a sequence of movies and the duration in minutes: movie_plan_items (id, movie_plan_id, movie_id, start_minutes, end_minutes) A specific instance of that plan happens in: movie_schedules (id, movie_plan_id, start_at) However the schedule items can be calculated from the movie_plan_items and the schedule start time by adding the minutes create view movie_schedule_items as select CONCAT(p.id, '-', s.id) as id, s.id as movie_schedule_id, p.id as movie_plan_item_id, p.movie_id, p.movie_plan_id, (s.start_at + INTERVAL p.start_minutes MINUTE) as start_at, (s.start_at + INTERVAL p.end_minutes MINUTE) as end_at from movie_plan_items p, movie_schedules s where s.movie_plan_id=p.movie_plan_id; I have a model over this view (readonly), it works ok, except that the id is right now a string. I now want to add a polymorphic property (like comments) to various of the previous tables. Therefore for movie_schedule_items I need a unique and persistent numeric id. I have the following dilemma: I could avoid the id and have movie_schedule_items just use the movie_plan_id and movie_schedule_id as a compound key, as it should. But Rails sucks in this regard. I could create an id using String#hash or a md5, thus making it slower or collision prone (and IIRC String#hash is no longer persistent across processes in Ruby 1.9) Any ideas on how to handle this situation?

  • Easy HTTPS to PHP script

    - by Tom
    Hi, here is my scenario: I have a website with php, mySQL. I have a software application that has a login screen and sends usernames and passwords over the web by http: public String GetWebPageSource(String pURL) { try { byte[] vReceivedBytes = null; using (System.Net.WebClient vWebClient = new System.Net.WebClient()) { vReceivedBytes = vWebClient.DownloadData(pURL); } int vBomLen = 3; byte[] vStrippedBytes = new byte[vReceivedBytes.Length - vBomLen]; Array.Copy(vReceivedBytes, vBomLen, vStrippedBytes, 0, vReceivedBytes.Length - vBomLen); return System.Text.Encoding.UTF8.GetString(vStrippedBytes); } catch (Exception e) { Console.WriteLine(e.Message); return null; } } So to send a username and password I would write: GetWebPageSource("http://mywebsite.com/Login.php?username=stackoverflow&password=iscool") and the php file would spit out some text saying whether the password is accepted or denied. However this is NOT secure. So I want to make it secure... https. How easy is it to integrate https? How much will the code change? How much do I have to handle? What is transparent to me. Do I have to check if a cookie already exists and if not write the methods for authentication or is there librarys already provided that will do it for me?

    I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps.

  • ASP.NET MVC Query Help

    I have the following Index method on my app that shows a bunch of articles: public ActionResult Index(String query) { var ArticleQuery = from m in _db.ArticleSet select m; if (!string.IsNullOrEmpty(query)) { ArticleQuery = ArticleQuery.Where(m => m.headline.Contains(query)); } //ArticleQuery = ArticleQuery.OrderBy(m.posted descending); return View(ArticleQuery.ToList()); } It also doubles as a search mechanism by grabbing a query string if it exists. Problem 1.) The OrderBy does not work, what do I need to change it to get it to show the results by posted date in descending order. Problem 2.) I am going to adding a VERY SIMPLE pagination, and therefore only want to show 4 results per page. How would I be best going about this? Thanks EDIT: In addition to problem 2, I'm looking for a simple Helper class solution to implement said pagination into my current code. This ones looks very good (http://weblogs.asp.net/andrewrea/archive/2008/07/01/asp-net-mvc-quot-pager-quot-html-helper.aspx), but how would I implement it into my application. Thanks.

  • How security of the systems might be improved using database procedures?

    - by Centurion
    The usage of Oracle PL/SQL procedures for controlling access to data often emphasized in PL/SQL books and other sources as being more secure approach. I'v seen several systems where all business logic related with data is performed through packages, procedures and functions, so application code becomes quite "dumb" and is only responsible for visualization part. I even heard some devs call such approaches and driving architects as database nazi :) because all logic code resides in database. I do know about DB procedure performance benefits, but now I'm interested in a "better security" when using thick client model. I assume such design mostly used when Oracle (and maybe MS SQL Server) databases are used. I do agree such approach improves security but only if there are not much users and every system user has a database account, so we might control and monitor data access through standard database user security. However, how such approach could increase the security for an average web system where thick clients are used: for example one database user with DML grants on all tables, and other users are handled using "users" and"user_rights" tables? We could use DB procedures, save usernames into context use that for filtering but vulnerability resides at the root - if the main database account is compromised than nothing will help. Of course in a real system we might consider at least several main users (for example frontend_db_user, backend_db_user).

I am using this registration: container.Register( AllTypes.FromAssemblyNamed("Assembly2") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Assembly1") .BasedOn(typeof(IReadDao<>)).WithService.Base()); The IReadDao<Product> works great. The container gives me ProductDao. But if I try to get IProductDao, the container throws ComponentNotFoundException. How can I correctly configure the registration?

  • Why my oracleParameter doesnt work?

    - by user1824356
    I'm a .NET developer and this is the first time i work with oracle provider (Oracle 10g and Framework 4.0). When i add parameter to my command in this way: objCommand.Parameters.Add("pc_cod_id", OracleType.VarChar, 4000).Value = codId; objCommand.Parameters.Add("pc_num_id", OracleType.VarChar, 4000).Value = numId; objCommand.Parameters.Add("return_value", OracleType.Number).Direction = ParameterDirection.ReturnValue; objCommand.Parameters.Add("pc_email", OracleType.VarChar, 4000).Direction = ParameterDirection.Output; I have no problem with the result. But when a add parameter in this way: objCommand.Parameters.Add(CreateParameter(PC_COD_ID, OracleType.VarChar, codId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(PC_NUM_ID, OracleType.VarChar, numId, ParameterDirection.Input)); objCommand.Parameters.Add(CreateParameter(RETURN_VALUE, OracleType.Number, ParameterDirection.ReturnValue)); objCommand.Parameters.Add(CreateParameter(PC_EMAIL, OracleType.VarChar, ParameterDirection.Output)); The implementation of that function is: protected OracleParameter CreateParameter(string name, OracleType type, ParameterDirection direction) { OracleParameter objParametro = new OracleParameter(name, type); objParametro.Direction = direction; if (type== OracleType.VarChar) { objParametro.Size = 4000; } return objParametro; } All my result are a empty string. My question is, these way to add parameters are not the same? And if no, what is the difference? Thanks :) Add: Sorry i forgot mention "CreateParameter" is a function with multiple implementations the base is the above function, the other use that. protected OracleParameter CreateParameter(string name, OracleType type, object value, ParameterDirection direction) { OracleParameter objParametro = CreateParameter(name, type, value); objParametro.Direction = direction; return objParametro; } The last parameters doesn't need value because those are output parameter, those bring me data from the database.

  • SQL Server Connection Timeout C#

    - by Termin8tor
    First off I'd like to let everyone know I have searched my particular problem and can't seem to find what's causing my problem. I have an SQL Server 2008 instance running on a network machine and a client I have written connecting to it. To connect I have a small segment of code that establishes a connection to an sql server 2008 instance and returns a DataTable populated with the results of whatever query I run against the server, all pretty standard stuff really. Anyway the issue is, whenever I open my program and call this method, upon the first call to my method, regardless as to what I've set my Connection Timeout value as in the connection string, it takes about 15 seconds and then times out. Bizarrely though the second or third call I make to the method will work without a problem. I have opened up the ports for SQL Server on the server machine as outlined in this article: How to Open firewall ports for SQL Server and verified that it is correctly configured. Can anyone see a particular problem in my code? string _connectionString = "Server=" + @Properties.Settings.Default.sqlServer + "; Initial Catalog=" + @Properties.Settings.Default.sqlInitialCatalog + ";User Id=" + @Properties.Settings.Default.sqlUsername + ";Password=" + @Properties.Settings.Default.sqlPassword + "; Connection Timeout=1"; private DataTable ExecuteSqlStatement(string command) { using (SqlConnection conn = new SqlConnection(_connectionString)) { try { conn.Open(); using (SqlDataAdapter adaptor = new SqlDataAdapter(command, conn)) { DataTable table = new DataTable(); adaptor.Fill(table); return table; } } catch (SqlException e) { throw e; } } } The SqlException that is caught at my catch is : "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." This occurs at the conn.Open(); line in the code snippet I have included. If anyone has any ideas that'd be great!
