  • Creating a Predicate Builder extension method

    - by Rippo
    I have a Kendo UI Grid that I am currently allowing filtering on multiple columns. I am wondering if there is a an alternative approach removing the outer switch statement? Basically I want to able to create an extension method so I can filter on a IQueryable<T> and I want to drop the outer case statement so I don't have to switch column names. private static IQueryable<Contact> FilterContactList(FilterDescriptor filter, IQueryable<Contact> contactList) { switch (filter.Member) { case "Name": switch (filter.Operator) { case FilterOperator.StartsWith: contactList = contactList.Where(w => w.Firstname.StartsWith(filter.Value.ToString()) || w.Lastname.StartsWith(filter.Value.ToString()) || (w.Firstname + " " + w.Lastname).StartsWith(filter.Value.ToString())); break; case FilterOperator.Contains: contactList = contactList.Where(w => w.Firstname.Contains(filter.Value.ToString()) || w.Lastname.Contains(filter.Value.ToString()) || (w.Firstname + " " + w.Lastname).Contains( filter.Value.ToString())); break; case FilterOperator.IsEqualTo: contactList = contactList.Where(w => w.Firstname == filter.Value.ToString() || w.Lastname == filter.Value.ToString() || (w.Firstname + " " + w.Lastname) == filter.Value.ToString()); break; } break; case "Company": switch (filter.Operator) { case FilterOperator.StartsWith: contactList = contactList.Where(w => w.Company.StartsWith(filter.Value.ToString())); break; case FilterOperator.Contains: contactList = contactList.Where(w => w.Company.Contains(filter.Value.ToString())); break; case FilterOperator.IsEqualTo: contactList = contactList.Where(w => w.Company == filter.Value.ToString()); break; } break; } return contactList; } Some additional information, I am using NHibernate Linq. Also another problem is that the "Name" column on my grid is actually "Firstname" + " " + "LastName" on my contact entity. We can also assume that all filterable columns will be strings.

  • Why MSMQ won't send a space character?

    - by cyclotis04
    I'm exploring MSMQ services, and I wrote a simple console client-server application that sends each of the client's keystrokes to the server. Whenever hit a control character (DEL, ESC, INS, etc) the server understandably throws an error. However, whenever I type a space character, the server receives the packet but doesn't throw an error and doesn't display the space. Server: namespace QIM { class Program { const string QUEUE = @".\Private$\qim"; static MessageQueue _mq; static readonly object _mqLock = new object(); static XmlSerializer xs; static void Main(string[] args) { lock (_mqLock) { if (!MessageQueue.Exists(QUEUE)) _mq = MessageQueue.Create(QUEUE); else _mq = new MessageQueue(QUEUE); } xs = new XmlSerializer(typeof(string)); _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); while (Console.ReadKey().Key != ConsoleKey.Escape) { } } static void OnReceive(IAsyncResult result) { Message msg; lock (_mqLock) { try { msg = _mq.EndReceive(result); Console.Write("."); Console.Write(xs.Deserialize(msg.BodyStream)); } catch (Exception ex) { Console.Write(ex); } } _mq.BeginReceive(new TimeSpan(0, 1, 0), new object(), OnReceive); } } } Client: namespace QIM_Client { class Program { const string QUEUE = @".\Private$\qim"; static MessageQueue _mq; static void Main(string[] args) { if (!MessageQueue.Exists(QUEUE)) _mq = MessageQueue.Create(QUEUE); else _mq = new MessageQueue(QUEUE); ConsoleKeyInfo key = new ConsoleKeyInfo(); while (key.Key != ConsoleKey.Escape) { key = Console.ReadKey(); _mq.Send(key.KeyChar.ToString()); } } } } Client Input: Testing, Testing... Server Output: .T.e.s.t.i.n.g.,..T.e.s.t.i.n.g...... You'll notice that the space character sends a message, but the character isn't displayed.

  • Display part of an XML file while parsing it

    - by Andy M
    Hey, Consider the following XML file : <cookbook> <recipe xml:id="MushroomSoup"> <title>Quick and Easy Mushroom Soup</title> <ingredient name="Fresh mushrooms" quantity="7" unit="pieces"/> <ingredient name="Garlic" quantity="1" unit="cloves"/> </recipe> <recipe xml:id="AnotherRecipe"> <title>XXXXXXX</title> <ingredient name="Tomatoes" quantity="8" unit="pieces"/> <ingredient name="PineApples" quantity="2" unit="cloves"/> </recipe> </cookbook> Let's say I want to parse this file and gather each recipe as XML, each one as a separated QString. For example, I would like to have a QString that contains : <recipe xml:id="MushroomSoup"> <title>Quick and Easy Mushroom Soup</title> <ingredient name="Fresh mushrooms" quantity="7" unit="pieces"/> <ingredient name="Garlic" quantity="1" unit="cloves"/> </recipe> How could I do this ? Do you guys know a quick and clean method to perform this ? Thanks in advance for your help !

  • Fractional to Decimal Form.

    - by ThePower
    Hi, there probably isn't an answer to this apart from "Create it yourself", but you never know, there might be some string representation for this. Basically, I would like to display number values as fractional instead of decimal when displaying the values as a string. Instead of a value displaying as: 1.1428571428571428571428571428571 I would prefer it to display as 8/7 Is there any way of doing this without writing the functionality myself? Regards Lloyd

  • How are integers converted to strings under the hood?

    - by CrazyJugglerDrummer
    I suppose the real question is how to convert base2/binary to base10. The most common application of this would probably be in creating strings for output: turning a chunk of binary numerical data into an array of characters. How exactly is this done? my guess: Seeing as there probably isn't a string predefined for each numerical value, I'm guessing that the computer goes through each bit of the integer from right to left, each time incrementing the appropriate values in the char array/base10 notation places. If we take the number 160 in binary (10100000), it would know that a 1 in the 8th place means 128, so it places 1 into the third column, 2 in the second, and 8 in the third. The 1 in the 6th column means 32, and it would add those values to the second and first place, carrying over if needed. After this it's an easy conversion to actual char codes.

  • __toString magic and type coercion

    - by TomcatExodus
    I've created a Template class for managing views and their associated data. It implements Iterator and ArrayAccess, and permits "sub-templates" for easy usage like so: <p><?php echo $template['foo']; ?></p> <?php foreach($template->post as $post): ?> <p><?php echo $post['bar']; ?></p> <?php endforeach; ?> Anyways, rather than using inline core functions, such as hash() or date(), I figured it would be useful to create a class called TemplateData, which would act as a wrapper for any data stored in the templates. This way, I can add a list of common methods for formatting, for example: echo $template['foo']->asCase('upper'); echo $template['bar']->asDate('H:i:s'); //etc.. When a value is set via $template['foo'] = 'bar'; in the controllers, the value of 'bar' is stored in it's own TemplateData object. I've used the magic __toString() so when you echo a TemplateData object, it casts to (string) and dumps it's value. However, despite the mantra controllers and views should not modify data, whenever I do something like this: $template['foo'] = 1; echo $template['foo'] + 1; //exception It dies on a Object of class TemplateData could not be converted to int; Unless I recast $template['foo'] to a string: echo ((string) $template['foo']) + 1; //outputs 2 Sort of defeats the purpose having to jump through that hoop. Are there any workarounds for this sort of behavior that exist, or should I just take this as it is, an incidental prevention of data modification in views?

  • Creating a custom format string in a dataGridView

    - by Andy
    I have a dataGridView whose dataSource is a dataTable. My problem is that I want certain columns to be displayed in Hex. I can get that far with using something like this: foreach (DataGridViewColumn c in grid.Columns) { if (DISPLAYED_IN_HEX.Contains(c.Name)) { c.DefaultCellStyle.Format = "X"; } } My issue though is that I want this hex value prepended with 0x so as not to confuse anyone that they are in hexidecimal form. The values in the dataTable are various integral types. I looked into creating a custom IFormatProvider, but I don't think my coding skills are up to that par yet. Any other possible solutions?

  • Question about effective logging in C#

    - by MartyIX
    I've written a simple class for debugging and I call the method Debugger.WriteLine(...) in my code like this: Debugger.WriteLine("[Draw]", "InProgress", "[x,y] = " + x.ToString("0.00") + ", " + y.ToString("0.00") + "; pos = " + lastPosX.ToString() + "x" + lastPosY.ToString() + " -> " + posX.ToString() + "x" + posY.ToString() + "; SS = " + squareSize.ToString() + "; MST = " + startTime.ToString("0.000") + "; Time = " + time.ToString() + phase.ToString(".0000") + "; progress = " + progress.ToString("0.000") + "; step = " + step.ToString() + "; TimeMovementEnd = " + UI.MovementEndTime.ToString()); The body of the procedure Debugger.WriteLine is compiled only in Debug mode (directives #if, #endif). What makes me worry is that I often need ToString() in Debugger.WriteLine call which is costly because it creates still new strings (for changing number for example). How to solve this problem? A few points/questions about debugging/tracing: I don't want to wrap every Debugger.WriteLine in an IF statement or to use preprocessor directives in order to leave out debugging methods because it would inevitable lead to a not very readable code and it requires too much typing. I don't want to use any framework for tracing/debugging. I want to try to program it myself. Are Trace methods (http://msdn.microsoft.com/en-us/library/system.diagnostics.trace.aspx) left out if compiling in release mode? If it is so is it possible that my methods would behave similarly? http://msdn.microsoft.com/en-us/library/fht0f5be.aspx output = String.Format("You are now {0} years old.", years); Which seems nice. Is it a solution for my problem with ToString()?

  • mocking collection behavior with Moq

    - by Stephen Patten
    Hello, I've read through some of the discussions on the Moq user group and have failed to find an example and have been so far unable to find the scenario that I have. Here is my question and code: // 6 periods var schedule = new List<PaymentPlanPeriod>() { new PaymentPlanPeriod(1000m, args.MinDate.ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(1).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(2).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(3).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(4).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(5).ToString()) }; // Now the proxy is correct with the schedule helper.Setup(h => h.GetPlanPeriods(It.IsAny<String>(), schedule)); Then in my tests I use Periods but the Mocked _PaymentPlanHelper never populates the collection, see below for usage: public IEnumerable<PaymentPlanPeriod> Periods { get { if (CanCalculateExpression()) _PaymentPlanHelper.GetPlanPeriods(this.ToString(), _PaymentSchedule); return _PaymentSchedule; } } Now if I change the mocked object to use another overloaded method of GetPlanPeriods that returns a List like so : var schedule = new List<PaymentPlanPeriod>() { new PaymentPlanPeriod(1000m, args.MinDate.ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(1).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(2).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(3).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(4).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(5).ToString()) }; helper.Setup(h => h.GetPlanPeriods(It.IsAny<String>())).Returns(new List<PaymentPlanPeriod>(schedule)); List<PaymentPlanPeriod> result = new _PaymentPlanHelper.GetPlanPeriods(this.ToString()); This works as expected. Any pointers would be awesome, as long as you don't bash my architecture... :) Thank you, Stephen

  • How to convert an arbitrary object to String with JSTL? (calling toString())

    - by hstoerr
    Is there any way to call toString() on an object with the JSTL? (I need the String representation of an enum as index in a map in a JSP EL expression.) I hoped something like ${''+object} would work like in java, but JSTL isn't that nice, and there does not seem to be any function that does it. Clarification: I have a variable somemap that maps Strings to Strings, and I have a variable someenum that is an enumeration. I'd like to do something like ${somemap[someenum.toString()]}. (Of course .toString() does not work, but what does?)

    Hi I m adding custom control to my flowlayoutpanel , its a sort of forex data , refresh every second , so on each timer tick , i m adding a control , changing controls button text , then adding it to flowlayout panel , i m doing it at each 100ms timer tick , it takeing tooo much CPU , here is my custom Control . public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private void UserControl1_Load(object sender, EventArgs e) { } public void displaydata(string name , string back3price , string back3 , string back2price , string back2 , string back1price , string back1 , string lay3price , string lay3 , string lay2price , string lay2 , string lay1price , string lay1 ) { lblrunnerName.Text = name.ToString(); btnback3.Text = back3.ToString() + "\n" + back3price.ToString(); btnback2.Text = back2.ToString() + "\n" + back2price.ToString(); btnback1.Text = back1.ToString() + "\n" + back1price.ToString(); btnlay1.Text = lay1.ToString() + "\n" + lay1price.ToString(); btnlay2.Text = lay2.ToString() + "\n" + lay2price.ToString(); btnlay3.Text = lay3.ToString() + "\n" + lay3price.ToString(); } and here is how i m adding control; private void timer1_Tick(object sender, EventArgs e) { localhost.marketData[] md; md = ser.getM1(); flowLayoutPanel1.Controls.Clear(); foreach (localhost.marketData item in md) { UserControl1 ur = new UserControl1(); ur.Name = item.runnerName + item.runnerID; ur.displaydata(item.runnerName, item.back3price, item.back3, item.back2price, item.back2, item.back1price, item.back1, item.lay3price, item.lay3, item.lay2price, item.lay2, item.lay1price, item.lay1); flowLayoutPanel1.SuspendLayout(); flowLayoutPanel1.Controls.Add(ur); flowLayoutPanel1.ResumeLayout(); } } now its happing on 10 times on each send , taking 60% of my Core2Duo cpu . is there any other way , i can just add contols first time , and then change the text of cutom controls buttons on runtime on each refresh or timer tick i m using c# .Net

  • Nullpointerexcption & abrupt IOStream closure with inheritence and subclasses

    - by user1401652
    A brief background before so we can communicate on the same wave length. I've had about 8-10 university courses on programming from data structure, to one on all languages, to specific ones such as java & c++. I'm a bit rusty because i usually take 2-3 month breaks from coding. This is a personal project that I started thinking of two years back. Okay down to the details, and a specific question, I'm having problems with my mutator functions. It seems to be that I am trying to access a private variable incorrectly. The question is, am I nesting my classes too much and trying to mutate a base class variable the incorrect way. If so point me in the way of the correct literature, or confirm this is my problem so I can restudy this information. Thanks package GroceryReceiptProgram; import java.io.*; import java.util.Vector; public class Date { private int hour, minute, day, month, year; Date() { try { BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in)); System.out.println("What's the hour?

  • Simply doing modelType.ToString() isn't sufficient, How can i use it via Activator.CreateInstance?

    - by programmerist
    public class MyController { public object CreateByEnum(DataModelType modeltype) { string enumText = modeltype.ToString(); // will return for example "Company" Type classType = Type.GetType(enumText); // the Type for Company class object t = Activator.CreateInstance(classType); // create an instance of Company class return t; } } public class CompanyView { public static List<Personel> GetPersonel() { MyController controller = new MyController(); _Company company = controller.CreateByEnum(DataModelType.Company) as _Company; return company.GetPersonel(); } } public enum DataModelType { xyz, klm, tucyz, Company } Yes, I agree Activator.CreateInstance() is very useful. Unfortunately, I need to pass in the correct type. That means building the correct string to pass to Type.GetType(). If I trace through the call to Controller.CreatebyEnum() in the code I posted above, simply doing modelType.ToString() isn't sufficient, even for the case of DataModelType.Company. My solution'll be maintenance bottleneck. What would be better is something that takes the results of modelType.ToString() and then recursively searches through all the types found in all the assemblies loaded in the current AppDomain. According to MSDN, Type.GetType() only searches the current calling assembly, and mscorlib.dll. How can i do that? . i need best performance?

  • search a collection for a specific keyword

    - by icelated
    What i want to do is search a hashset with a keyword.. I have 3 classes... main() Library Item(CD, DVD,Book classes) In library i am trying to do my search of the items in the hashsets.. In Item class is where i have the getKeywords function.. here is the Items class... import java.io.PrintStream; import java.util.Collection; import java.util.*; class Item { private String title; private String [] keywords; public String toString() { String line1 = "title: " + title + "\n" + "keywords: " + Arrays.toString(keywords); return line1; } public void print() { System.out.println(toString()); } public Item() { } public Item(String theTitle, String... theKeyword) { this.title = theTitle; this.keywords = theKeyword; } public String getTitle() { return title; } public String [] getKeywords() { return keywords; } } class CD extends Item { private String artist; private String [] members; // private String [] keywords; private int number; public CD(String theTitle, String theBand, int Snumber, String... keywords) { super(theTitle, keywords); this.artist = theBand; this.number = Snumber; // this.keywords = keywords; } public void addband(String... member) { this.members = member; } public String getArtist() { return artist; } public String [] getMembers() { return members; } // public String [] getKeywords() // { // return keywords; //} public String toString() { return "-Music-" + "\n" + "band: " + artist + "\n" + "# songs: " + number + "\n" + "members: " + Arrays.toString(members) + "\n" + super.toString() // + "keywords: " + Arrays.toString(keywords) + "\n" + "\n" ; } public void print() { System.out.println(toString()); } } class DVD extends Item { private String director; private String [] cast; private int scenes; // private String [] keywords; public DVD(String theTitle, String theDirector, int nScenes, String... keywords) { super(theTitle, keywords); this.director = theDirector; this.scenes = nScenes; // this.keywords = keywords; } public void addmoviecast(String... members) { this.cast = members; } public String [] getCast() { return cast; } public String getDirector() { return director; } // public String [] getKeywords() // { // return keywords; // } public String toString() { return "-Movie-" + "\n" + "director: " + director + "\n" + "# scenes: " + scenes + "\n" + "cast: " + Arrays.toString(cast) + "\n" + super.toString() // + "keywords: " + Arrays.toString(keywords) + "\n" + "\n" ; } public void print() { System.out.println(toString()); } } class Book extends Item { private String author; private int pages; public Book(String theTitle, String theAuthor, int nPages, String... keywords) { super(theTitle, keywords); this.author = theAuthor; this.pages = nPages; // this.keywords = keywords; } public String getAuthor() { return author; } //public String [] getKeywords() // { // return keywords; //} public void print() { System.out.println(toString()); } public String toString() { return "-Book-" + "\n" + "Author: " + author + "\n" + "# pages " + pages + "\n" + super.toString() // + "keywords: " + Arrays.toString(keywords) + "\n" + "\n" ; } } I hope i didnt confuse you? I need help with the itemsForKeyword(String keyword) function.. the first keyword being passed in is "science fiction" and i want to search the keywords in the sets and return the matches.. What am i doing so wrong? Thank you
