  • Reworking my singly linked list

    - by Stradigos
    Hello everyone, thanks for taking the time to stop by my question. Below you will find my working SLL, but I want to make more use of C# and, instead of having two classes, SLL and Node, I want to use Node's constructors to do all the work (To where if you pass a string through the node, the constructor will chop it up into char nodes). The problem is, after an a few hours of tinkering, I'm not really getting anywhere... using System; using System.Collections.Generic; using System.Text; using System.IO; namespace PalindromeTester { class Program { static void Main(string[] args) { SLL mySLL = new SLL(); mySLL.add('a'); mySLL.add('b'); mySLL.add('c'); mySLL.add('d'); mySLL.add('e'); mySLL.add('f'); Console.Out.WriteLine("Node count = " + mySLL.count); mySLL.reverse(); mySLL.traverse(); Console.Out.WriteLine("\n The header is: " + mySLL.gethead); Console.In.ReadLine(); } class Node { private char letter; private Node next; public Node() { next = null; } public Node(char c) { this.data = c; } public Node(string s) { } public char data { get { return letter; } set { letter = value; } } public Node nextNode { get { return next; } set { next = value; } } } class SLL { private Node head; private int totalNode; public SLL() { head = null; totalNode = 0; } public void add(char s) { if (head == null) { head = new Node(); head.data = s; } else { Node temp; temp = new Node(); temp.data = s; temp.nextNode = head; head = temp; } totalNode++; } public int count { get { return totalNode; } } public char gethead { get { return head.data; } } public void traverse() { Node temp = head; while(temp != null) { Console.Write(temp.data + " "); temp = temp.nextNode; } } public void reverse() { Node q = null; Node p = this.head; while(p!=null) { Node r=p; p=p.nextNode; r.nextNode=q; q=r; } this.head = q; } } } } Here's what I have so far in trying to work it into Node's constructors: using System; using System.Collections.Generic; using System.Text; using System.IO; namespace PalindromeTester { class Program { static void Main(string[] args) { //Node myList = new Node(); //TextReader tr = new StreamReader("data.txt"); //string line; //while ((line = tr.ReadLine()) != null) //{ // Console.WriteLine(line); //} //tr.Close(); Node myNode = new Node("hello"); Console.Out.WriteLine(myNode.count); myNode.reverse(); myNode.traverse(); // Console.Out.WriteLine(myNode.gethead); Console.In.ReadLine(); } class Node { private char letter; private Node next; private Node head; private int totalNode; public Node() { head = null; totalNode = 0; } public Node(char c) { if (head == null) { head = new Node(); head.data = c; } else { Node temp; temp = new Node(); temp.data = c; temp.nextNode = head; head = temp; } totalNode++; } public Node(string s) { foreach (char x in s) { new Node(x); } } public char data { get { return letter; } set { letter = value; } } public Node nextNode { get { return next; } set { next = value; } } public void reverse() { Node q = null; Node p = this.head; while (p != null) { Node r = p; p = p.nextNode; r.nextNode = q; q = r; } this.head = q; } public void traverse() { Node temp = head; while (temp != null) { Console.Write(temp.data + " "); temp = temp.nextNode; } } public int count { get { return totalNode; } } } } } Ideally, the only constructors and methods I would be left with are Node(), Node(char c), Node(string s), Node reserve() and I'll be reworking traverse into a ToString overload. Any suggestions?

  • Django: Implementing a referral program

    - by Hellnar
    Hello, I have an ecommerce website that works in a classical way: people sign up, buy a product with their CC. It uses the default Django auth system for users and registration and session framework. Now I want to implement a referral system to my system where people can invite other people by giving their referral link (ie mysite.com/referral/123123/ ) and if a person signs up AND buys an item, the inviter gets 5$. How can this the implemented ?

  • How to check which point is cause of problem with MQ?

    - by Fuangwith S.
    I use MQ for send/receive message between my system and other system. Sometime I found that no response message in response queue, yet other system have already put response message into response queue (check from log). So, how to check which point is cause of problem, how to prove message is not arrive to my response queue. In addition, when message arrive my queue it will be written to log file.

  • How do you measure latency in low-latency environments?

    - by Ajaxx
    Here's the setup... Your system is receiving a stream of data that contains discrete messages (usually between 32-128 bytes per message). As part of your processing pipeline, each message passes through two physically separate applications which exchange the data using a low-latency approach (such as messaging over UDP) or RDMA and finally to a client via the same mechanism. Assuming you can inject yourself at any level, including wire protocol analysis, what tools and/or techniques would you use to measure the latency of your system. As part of this, I'm assuming that every message that is delivered to the system results in a corresponding (though not equivalent) message being pushed through the system and delivered to the client. The only tool that I've seen on the market like this is TS-Associates TipOff. I'm sure that with the right access you could probably measure the same information using a wire analysis tool (ala wireshark) and the right dissectors, but is this the right approach or are there any commodity solutions that I can use?

  • Strange behavior of move with strings

    - by Umair Ahmed
    I am testing some enhanced string related functions with which I am trying to use move as a way to copy strings around for faster, more efficient use without delving into pointers. While testing a function for making a delimited string from a TStringList, I encountered a strange issue. The compiler referenced the bytes contained through the index when it was empty and when a string was added to it through move, index referenced the characters contained. Here is a small downsized barebone code sample:- unit UI; interface uses System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.Layouts, FMX.Memo; type TForm1 = class(TForm) Results: TMemo; procedure FormCreate(Sender: TObject); end; var Form1: TForm1; implementation {$R *.fmx} function StringListToDelimitedString ( const AStringList: TStringList; const ADelimiter: String ): String; var Str : String; Temp1 : NativeInt; Temp2 : NativeInt; DelimiterSize : Byte; begin Result := ' '; Temp1 := 0; DelimiterSize := Length ( ADelimiter ) * 2; for Str in AStringList do Temp1 := Temp1 + Length ( Str ); SetLength ( Result, Temp1 ); Temp1 := 1; for Str in AStringList do begin Temp2 := Length ( Str ) * 2; // Here Index references bytes in Result Move ( Str [1], Result [Temp1], Temp2 ); // From here the index seems to address characters instead of bytes in Result Temp1 := Temp1 + Temp2; Move ( ADelimiter [1], Result [Temp1], DelimiterSize ); Temp1 := Temp1 + DelimiterSize; end; end; procedure TForm1.FormCreate(Sender: TObject); var StrList : TStringList; Str : String; begin // Test 1 : StringListToDelimitedString StrList := TStringList.Create; Str := ''; StrList.Add ( 'Hello1' ); StrList.Add ( 'Hello2' ); StrList.Add ( 'Hello3' ); StrList.Add ( 'Hello4' ); Str := StringListToDelimitedString ( StrList, ';' ); Results.Lines.Add ( Str ); StrList.Free; end; end. Please devise a solution and if possible, some explanation. Alternatives are welcome too.

  • Load thumbnail image into PictureBox from directory

    - by zaidwaqi
    Hi, I use the following code to get thumbnail of image in Resources, and display on Picturebox. Image tmp = (System.Drawing.Image)myManager.GetObject(tempImage); cfgPassPicture[m].Image = tmp.GetThumbnailImage(40, 40, new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), System.IntPtr.Zero); How do I do this for images in directory (instead of resources), given only the URL? I can load image into PictureBox via ImageLocation property, but not sure how to use Image property of PictureBox for this. Thanks

  • Is there a media/music player program that has a "biased" shuffle?

    - by Joel Coehoorn
    I know in iTunes and a few other apps you can get playlists for just "highly rated" songs, but that's not quite what I want. I want to hear the lower-rated stuff, too. If I didn't like the song at some level it wouldn't be in my library in the first place, and so even a one-star song is worth the occasional listen. However, I do want to hear five-star songs a lot more often than one-star songs, even though I think I have a lot more one-star songs in my music library. So does anyone know of media player software of plugin (preferrable free) that has a shuffle mode that is biased towards songs that are rated higher, without completely excluding those that are rated lower? Right now I prefer windows media player, so a plugin for that would be ideal, but I'm not married to media player, either. Any music software that will do this would be worth some attention.

  • VBA + Polymorphism: Override worksheet functions from 3rd party

    - by phi
    my company makes extensive use of a data provider using a (closed source) VBA plugin. In principal, every query follows follows a certain structure: Fill one cell with a formula, where arguments to the formula specify the query the range of that formula is extended (not an arrray formula!) and cells below/right are filled with data For this to work, however, a user has to have a terminal program installed on the machine, as well as a com-plugin referenced in VBA/Excel. My Problem These Excelsheets are used and extended by multiple users, and not all of them have access to the data provider. While they can open the sheet, it will recalculate and the data will be gone. However, frequent recalculation is required. I would like every user to be able to use the sheets, without executing a very specific set of formulas. Attempts remove the reference on those computers where I do not have terminal access. This generates a NAME error i the cell containing the query (acceptable), but this query overrides parts of the data (not acceptable) If you allow the program to refresh, all data will be gone after a failed query Replace all formulas with the plain-text result in the respective cells (press a button and loop over every cell...). Obviously destroys any refresh-capabilities the querys offer for all subsequent users, so pretty bad, too. A theoretical idea, and I'm not sure how to implement it: Replace the functions offered by the plugin with something that will be called either first (and relay the query through to the original function, if thats available) or instead of the original function (by only deploying the solution on non-terminal machines), which just returns the original value. More specifically, if my query function is used like this: =GETALLDATA(Startdate, Enddate, Stockticker, etc) I would like to transparently swap the function behind the call. Do you see any hope, or am I lost? I appreciate your help. PS: Of course I'm talking about Bloomberg... Some additional points to clarify issues raise by Frank: The formula in the sheets may not be changed. This is mission-critical software, and its way too complex for any sane person to try and touch it. Only excel and VBA may be used (which is the reason for the previous point...) It would be sufficient to prevent execution of these few specific formulas/functions on a specific machine for all excel sheets to come This looks more and more like a problem for stackoverflow ;-)

  • Using Off-The-Record and Trillian Astra together

    - by h4rrydog
    Does anyone know how to use Off-the-Record (OTR) with Trillian Astra? I've found the OTR for Trillian plugin here: http://trillianotr.kittyfox.net/ For the most part, it works and I can use OTR for chats with other people who initiate them or with people whose fingerprints I have. But I cannot initiate one myself to a user for whom I don't have a fingerprint. Other users have referred to using the OTR icon/menu to initiate an OTR chat, but there is no OTR icon or menu in the conversations window. I think this plugin was developed for a previous version of Trillian and not Astra (4.2). Anyone have any ideas on how to make this work? Thanks in advance!

  • stuck with enable session state

    - by Shrewd Demon
    hi i have an application wherein i am accessing the Session object in the CommonCode.cs file that resides in the App_Code folder. But when the session object is accessed the application throws me an error: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. Now i have already enabled the session state property in the web.config file, here is my code from the web.config file: <pages enableSessionState="true" autoEventWireup="true"> <controls> <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </controls> </pages> I dont understand why am i still getting that error !! please help ! thanks a lot.

  • Create a strongly typed view which inherites a class which is concrete

    - by Ashwani K
    Hello All: I am having one class called BaseClass which contains some logic applicable to whole web site. In order to create a strongly typed view we need to inherit the page from System.Web.Mvc.ViewPage generic class. But In our case I have to Inherit the BaseClass from System.Web.Mvc.ViewPage to apply some common settings, but the BaseClass should be inherited from System.Web.Mvc.ViewPage< generic version. But I cannot inherit the BaseClass from System.Web.Mvc.ViewPage< as it will change other class also. So I created one more class of type BaseClass< inheriting it from System.Web.Mvc.ViewPage< and copied the whole code of BaseClass in BaseClass<. But the code in BaseClass is controlled by other team so it will be changed frequently so my BaseClass< should be in sync with BaseClass. Please help me in eliminating the code duplication or any other approach to make strongly typed View. Thanks Ashwani

    I'm trying to write a web part that access lists and add items in a specific list. The user modifies the web part and type in List Name, the web part has 3 TextBoxs and a Button. The user should enter data and press the save button, that should update the list and add these data in a new record. I'm using the following code to build my web part, but the save button doesn't update the list. I don't know what's wrong it just reload the page and add nothing. Edit: BTW the list am trying to update has three columns, First Name, Last Name, and Email, respectively. using System; using System.Web; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; using Microsoft.SharePoint.Utilities; using Microsoft.SharePoint.WebControls; using Microsoft.SharePoint.WebPartPages; using Microsoft.SharePoint.Security; namespace TimeSheetEntry { public class TimesheetEntry : System.Web.UI.WebControls.WebParts.WebPart { public TimesheetEntry() { } protected TextBox txtFirstName; protected TextBox txtLastName; protected TextBox txtEmail; protected Button btnSave; protected string listName = string.Empty; [WebBrowsable(true), WebDisplayName("List Name"), WebDescription("Enter List Name"), Personalizable(PersonalizationScope.User)] public string LN { get { return this.listName; } set { this.listName = value; } } protected override void CreateChildControls() { //initialize textboxes txtFirstName = new TextBox(); txtLastName = new TextBox(); txtEmail = new TextBox(); //initialize button btnSave = new Button(); btnSave.Text = "Save"; btnSave.Click += new EventHandler(btnSave_Click); } protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("<table width=100%>"); writer.Write("<tr>"); writer.Write("<td colspan=2>"); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>First:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtFirstName.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>Last Name:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtLastName.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>Email:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtEmail.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>"); writer.Write("</td>"); writer.Write("<td>"); btnSave.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("</table>"); } public void btnSave_Click(object sender, EventArgs e) { SPWeb web = SPContext.Current.Web; SPList timesheetList = web.Lists[this.listName]; SPListItem newTimesheetEntry = timesheetList.Items.Add(); newTimesheetEntry["First Name"] = txtFirstName.Text; newTimesheetEntry["Last Name"] = txtLastName.Text; newTimesheetEntry["Email"] = txtEmail.Text; newTimesheetEntry.Update(); timesheetList.Update(); } } }

  • Java String.indexOf and empty Strings

    - by tmeisenh
    I'm curious why the String.indexOf is returning a 0 (instead of -1) when asking for the index of an empty string within a string. The Javadocs only say this method returns the index in this String of the specified string, -1 if the string isn't found. System.out.println("FOO".indexOf("")); // outputs 0 wtf!!! System.out.println("FOO".indexOf("bar")); // outputs -1 as expected System.out.println("FOO".indexOf("F")); // outputs 0 as expected System.out.println("".indexOf("")); // outputs 0 as expected, I think

  • How can I execute a .sql from C#?

    - by J. Pablo Fernández
    For some integration tests I want to connect to the database and run a .sql file that has the schema needed for the tests to actually run, including GO statements. How can I execute the .sql file? (or is this totally the wrong way to go?) I've found a post in the MSDN forum showing this code: using System.Data.SqlClient; using System.IO; using Microsoft.SqlServer.Management.Common; using Microsoft.SqlServer.Management.Smo; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True"; FileInfo file = new FileInfo("C:\\myscript.sql"); string script = file.OpenText().ReadToEnd(); SqlConnection conn = new SqlConnection(sqlConnectionString); Server server = new Server(new ServerConnection(conn)); server.ConnectionContext.ExecuteNonQuery(script); } } } but on the last line I'm getting this error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.TypeInitializationException: The type initializer for '' threw an exception. --- .ModuleLoadException: The C++ module failed to load during appdomain initialization. --- System.DllNotFoundException: Unable to load DLL 'MSVCR80.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). I was told to go and download that DLL from somewhere, but that sounds very hacky. Is there a cleaner way to? Is there another way to do it? What am I doing wrong? I'm doing this with Visual Studio 2008, SQL Server 2008, .Net 3.5SP1 and C# 3.0.

  • Drag and Drop to explorer causing invalid FORMATETC (DV_E_FORMATETC) error

    - by JustABill
    I'm trying to use this excellent example to implement dropping virtual files into Windows Explorer. However, I'm stymied by this error. Towards the bottom, inside void System.Runtime.InteropServices.ComTypes.IDataObject.GetData(ref System.Runtime.InteropServices.ComTypes.FORMATETC formatetc, out System.Runtime.InteropServices.ComTypes.STGMEDIUM medium) on the first call to ((System.Runtime.InteropServices.ComTypes.IDataObject)this).GetDataHere(ref formatetc, ref medium); I'm getting back a DV_E_FORMATETC error. As far as I can tell, all the elements of the FORMATETC struct that are being passed in are valid: cfFormat is "Shell IDList Array" (-16141), ptd is 0, dwAspect is DVASPECT_CONTENT, lindex is -1, and tymed is TYMED_HGLOBAL. I'm kind of confused how there'd be a problem anyway, since this was generated by explorer. I know very little about COM interaction, so any help would be greatly appreciated.

  • Understanding Java Wait and Notify methods

    - by Maddy
    Hello all: I have a following program: import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; public class SimpleWaitNotify implements Runnable { final static Object obj = new Object(); static boolean value = true; public synchronized void flag() { System.out.println("Before Wait"); try { obj.wait(); } catch (InterruptedException e) { System.out.println("Thread interrupted"); } System.out.println("After Being Notified"); } public synchronized void unflag() { System.out.println("Before Notify All"); obj.notifyAll(); System.out.println("After Notify All Method Call"); } public void run() { if (value) { flag(); } else { unflag(); } } public static void main(String[] args) throws InterruptedException { ExecutorService pool = Executors.newFixedThreadPool(4); SimpleWaitNotify sWait = new SimpleWaitNotify(); pool.execute(sWait); SimpleWaitNotify.value = false; SimpleWaitNotify sNotify = new SimpleWaitNotify(); pool.execute(sNotify); pool.shutdown(); } } When I wait on obj, I get the following exception Exception in thread "pool-1-thread-1" java.lang.IllegalMonitorStateException: current thread not owner for each of the two threads. But if I use SimpleWaitNotify's monitor then the program execution is suspended. In other words, I think it suspends current execution thread and in turn the executor. Any help towards understanding what's going on would be duly appreciated. This is an area1 where the theory and javadoc seem straightforward, and since there aren't many examples, conceptually left a big gap in me.

  • Rails "rake test" crashing

    - by Homer J. Simpson
    Hi, this might be rather unspecific, but I'm trying to do 'rake test' on a new rails app, and end up with (in /Users/myname/dev/railstest/RailsApplication1) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" No other output. System is Leopard 10.5, Rails 2.3.5, Ruby 1.86 Any ideas ?
