• Get to Know a Candidate (2 of 25): Merlin Miller&ndash;American Third Position Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Meet Merlin Miller of American Third Position Party In addition to being American Third Position Party nominee, Miller is an independent film maker.  He is a graduate of West Point and has commanded two units in the United States Army.  After military service he worked as an industrial engineering manager for Michelin Tire.  He learned about film making by earning an MFA from the University of Southern California. Mr. Miller is on the ballot in: CO, NJ, and TN. In the 2000’s, Miller began taking an increasingly paleoconservative political stance.  He claimed that Hollywood “ surreptitiously seeks to destroy our European-American heritage and our Christian-based traditional values, and replace them with values that debase these traditional values and elevate minorities as paragons of virtue and wisdom....Today’s motion pictures, in concert with other forms of mass media entertainment, are the greatest enemies to the well-being of our progeny and the future of our country.” Miller states that he "doesn't like" interracial marriage; however, he does not support outlawing interracial marriage, either.  Miller has denied being anti-Semitic, instead claiming that he merely opposes "favoritism" granted to Jews in the film industry.  He also opposes illegal immigration and what he refers to as "wide open borders" in the United States. The American Third Position Party (A3P) is a third positionist American political party which promotes white supremacy.  It was officially launched in January 2010 (although in November 2009 it filed papers to get on a ballot in California) partially to channel the right-wing populist resentment engendered by the financial crisis of 2007–2010 and the policies of the Obama administration and defines its principal mission as representing the political interests of white Americans. The party takes a strong stand against immigration and globalization, and strongly supports an anti-interventionist foreign policy. Although the party does not support labor unions, they do strongly support the labor rights of the American working class on a platform of placing American workers first over illegal immigrant workers and banning of overseas corporate relocation of American industry and technology Third Position or Third Alternative refers to a revolutionary nationalist political position that emphasizes its opposition to both communism and capitalism. Advocates of Third Position politics typically present themselves as "beyond left and right", instead claiming to syncretize radical ideas from both ends of the political spectrum Learn more about Merlin Miller and American Third Position Party on Wikipedia.

• How to read cell data in excel and output to command prompt

  - by Max Ollerenshaw

  Hi All, I'm a sys admin and I am trying to learn how to use powershell... I have never done any type of scripting or coding before and I have been teaching myself online by learning from the technet script centre and online forums. What I am trying to accomplish is to open an excel spreadsheet get information from it (usernames and password) and then output it into the command prompt in powershell. When ever I try to do this I get an Exception calling "InvokeMember" anyway, here is the code I have so far: function Invoke([object]$m, [string]$method, $parameters) { $m.PSBase.GetType().InvokeMember( $method, [Reflection.BindingFlags]::InvokeMethod, $null, $m, $parameters,$ciUS ) } $ciUS = [System.Globalization.CultureInfo]'en-US' $objExcel = New-Object -comobject Excel.Application $objExcel.Visible = $False $objExcel.DisplayAlerts = $False $objWorkbook = Invoke $objExcel.Workbooks.Open "C:\PS\User Data.xls" Write-Host "Numer of worksheets: " $objWorkbook.Sheets.Count $objWorksheet = $objWorkbook.Worksheets.Item(1) Write-Host "Worksheet: " $objWorksheet.Name $Forename = $objWorksheet.Cells.Item(2,1).Text $Surname = $objWorksheet.Cells.Item(2,2).Text Write-Host "Forename: " $Forename Write-Host "Surname: " $Surname $objExcel.Quit() If (ps excel) { kill -name excel} I have read many different posts on forums and articles on how to try and get around the en-US problem but I cannot seem to get around it and hope that someone here can help! Here is the Exeption problem I mentioned: Exception calling "InvokeMember" with "6" argument(s): "Method 'System.Management.Automation.PSMethod.C:\PS\User Data.x ls' not found."

• Configuration for httphandler in classic mode

  - by happyspider

  I have to install an httphandler that needs to run on classic mode. I have created an application on the iis that uses a classic apppool and put the handler assembly there. The vendor gave me a configuration in the deployment document that looks like this: <system.web> <globalization requestEncoding="iso-8859-1" responseEncoding="iso-8859-1" /> <httpModules> </httpModules> <httpHandlers> <add verb="*" path="*" type="ProductName.ProductName, ProductName" /> </httpHandlers> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <handlers> <add name="someUnspecificName" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv2.0,bitness32" /> </handlers> </system.webServer> The error I get when requesting a URL on the application is a 404, so I guess the handle is not used at all. Does the configuration look ok for a 64bit system?

• Universities 2030: Learning from the Past to Anticipate the Future

  - by Mohit Phogat

  What will the landscape of international higher education look like a generation from now? What challenges and opportunities lie ahead for universities, especially “global” research universities? And what can university leaders do to prepare for the major social, economic, and political changes—both foreseen and unforeseen—that may be on the horizon? The nine essays in this collection proceed on the premise that one way to envision “the global university” of the future is to explore how earlier generations of university leaders prepared for “global” change—or at least responded to change—in the past. As the essays in this collection attest, many of the patterns associated with contemporary “globalization” or “internationalization” are not new; similar processes have been underway for a long time (some would say for centuries).[1] A comparative-historical look at universities’ responses to global change can help today’s higher-education leaders prepare for the future. Written by leading historians of higher education from around the world, these nine essays identify “key moments” in the internationalization of higher education: moments when universities and university leaders responded to new historical circumstances by reorienting their relationship with the broader world. Covering more than a century of change—from the late nineteenth century to the early twenty-first—they explore different approaches to internationalization across Europe, Asia, Australia, North America, and South America. Notably, while the choice of historical eras was left entirely open, the essays converged around four periods: the 1880s and the international extension of the “modern research university” model; the 1930s and universities’ attempts to cope with international financial and political crises; the 1960s and universities’ role in an emerging postcolonial international development apparatus; and the 2000s and the rise of neoliberal efforts to reform universities in the name of international economic “competitiveness.” Each of these four periods saw universities adopt new approaches to internationalization in response to major historical-structural changes, and each has clear parallels to today. Among the most important historical-structural challenges that universities confronted were: (1) fluctuating enrollments and funding resources associated with global economic booms and busts; (2) new modes of transportation and communication that facilitated mobility (among students, scholars, and knowledge itself); (3) increasing demands for applied science, technical expertise, and commercial innovation; and (4) ideological reconfigurations accompanying regime changes (e.g., from one internal regime to another, from colonialism to postcolonialism, from the cold war to globalized capitalism, etc.). Like universities today, universities in the past responded to major historical-structural changes by internationalizing: by joining forces across space to meet new expectations and solve problems on an ever-widening scale. Approaches to internationalization have typically built on prior cultural or institutional ties. In general, only when the benefits of existing ties had been exhausted did universities reach out to foreign (or less familiar) partners. As one might expect, this process of “reaching out” has stretched universities’ traditional cultural, political, and/or intellectual bonds and has invariably presented challenges, particularly when national priorities have differed—for example, with respect to curricular programs, governance structures, norms of academic freedom, etc. Strategies of university internationalization that either ignore or downplay cultural, political, or intellectual differences often fail, especially when the pursuit of new international connections is perceived to weaken national ties. If the essays in this collection agree on anything, they agree that approaches to internationalization that seem to “de-nationalize” the university usually do not succeed (at least not for long).

• Brazil is Hot for Social Media

  - by Mike Stiles

  Today’s guest blog is from Oracle SVP Product Development Reggie Bradford, fresh off a visit to Sao Paulo, Brazil where he spoke at the Dachis Social Business Summit and spent some time getting a personal taste for the astonishing growth of social in Brazil, both in terms of usage and engagement. I knew it was big, but I now have an all-new appreciation for why the Wall Street Journal branded Brazil the “social media capital of the universe.” Brazil has the world’s 5th largest economy, an expanding middle class, an active younger demo market, a connected & outgoing culture, and an ongoing embrace of the social media platforms. According to comScore's 2012 Brazil Digital Future in Focus report, 97% are using social media, and that’s not even taking mobile-only users into account. There were 65 million Facebook users in 2012, spending an average 535 minutes there, up 208%. It’s one of Twitter’s fastest growing markets and the 2nd biggest market for YouTube. Instagram usage has grown over 300% since last year. That by itself is exciting, but look at the opportunity for social marketing brands. 74% of Brazilian social users follow brands on Facebook, and 59% have praised a company on either Twitter or Facebook. A 2011 Oh! Panel study found 81% of social networkers there used social to research new products and 75% went there looking for discounts. B2C eCommerce sales in Brazil is projected to hit $26.9 billion by 2015. I bet I’m not the only one who sees great things ahead, and I was fortunate enough give a keynote ABRADI, an association of leading digital agencies in Brazil with 53 execs from 35 agencies attending. I was also afforded the opportunity to give my impressions of what’s going on in Brazil to Jornal Propoganda & Marketing, one of the most popular publications in Latin America for marketers. I conveyed that especially in an environment like Brazil, where social users are so willing to connect and engage brands, marketers need to back away from the heavy-handed, one-way messaging of old school advertising and move toward genuine relationships and trust-building. To aide in this, organizational and operation changes must be embraced inside the enterprise. We've talked often about the new, tighter partnership forming between the CIO and CMO. If this partnership is not encouraged, fostered and resourced, the increasing amount of time consumers spend on mobile and digital, and the efficiencies and integrations offered by cloud-based software cannot be exploited. These are the kinds of changes that can yield social data that, when combined with enterprise data, helps you come to know your social audiences intimately and predict their needs. Consumers are always connected and need your brand to be accessible at any time, be it for information or customer service. And, of course, all of this is happening quite publicly. The holistic, socially-enable enterprise connects social to customer service systems and all other customer touch points, facilitating the kind of immediate, real-time, gratifying response customers are coming to expect. Social users in Brazil are highly active and clearly willing to meet us as brands more than halfway. Empowering yourself with a social management technology platform will have you set up to maximize this booming social market…from listening & monitoring to engagement to analytics to workflow & automation to globalization & language support. Brands, it’s time to be as social as the great people of Brazil are. Obrigado! @reggiebradfordPhoto: Gualberto107, freedigitalphotos.net

• Pass value of a field to Silverlight ConverterParameter

  - by eidylon

  Hi all, I'm writing my very first Silverlight app. I have a datagrid with a column that has two labels, for the labels, i am using an IValueConverter to conditionally format the data. The label's "Content" is set as such: Content="{Binding HomeScore, Converter={StaticResource fmtshs}}" and Content="{Binding AwayScore, Converter={StaticResource fmtshs}}" The Convert method of my IValueConverter is such: Public Function Convert( ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert Dim score As Long = value, other As Long = parameter Return If(score < 0, "", If(score - other > 5, (other + 5).ToString, score.ToString) ) End Function So what i want to do is in the converter for HomeScore, i want to pass AwayScore to the ConverterParameter, and for AwayScore i want to pass the HomeScore to the converter. In the converter for either score i need to be able to know the value of the other score for formatting purposes. But i cannot figure out the syntax for binding the ConverterParameter to another field. I've tried the following: Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter=AwayScore}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={AwayScore}}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={Binding AwayScore}}" But none of those seem to work. How do i pass a field value to the ConverterParameter?

Am I missing something obvious? Rob

• MSMQ first Message.Body in queue is OK, all following Message.Body in queue are empty

  - by Andrew A

  I send a handful of identical (except for Id#, obviously) messages to an MSMQ queue on my local machine. The body of the messages is a serialized XElement object. When I try to process the first message in the queue, I am able to successfully de-serialize the Message.Body object and save it to file. However, when trying to process the next (or any subsequent) message, the Message.Body is absent, and an exception is thrown. I have verified the Message ID's are correct for the message attempting to be processed. The XML being serialized is properly formed. Any ideas? I am basing my code on the Microsoft MSMQ Book order sample found here: http://msdn.microsoft.com/en-us/library/ms180970%28VS.80%29.aspx // Create Envelope XML object XElement envelope = new XElement(env + "Envelope", new XAttribute(XNamespace.Xmlns + "env", env.NamespaceName) <snip> //Send envelope as message body MessageQueue myQueue = new MessageQueue(String.Format(@"FORMATNAME:DIRECT=OS:localhost\private$\mqsample")); myQueue.DefaultPropertiesToSend.Recoverable = true; // Prepare message Message myMessage = new Message(); myMessage.ResponseQueue = new MessageQueue(String.Format(System.Globalization.CultureInfo.InvariantCulture, @"FORMATNAME:DIRECT=TCP:192.168.1.217\private$\mqdemoAck")); myMessage.Body = envelope; // Send the message into the queue. myQueue.Send(myMessage,"message label"); //Retrieve messages from queue LabelIdMapping labelID = (LabelIdMapping)mqlistBox3.SelectedItem; System.Messaging.Message message = mqOrderQueue.ReceiveById(labelID.Id); The Message.Body value I see on the 1st retrieve is as expected: <?xml version="1.0" encoding="utf-8"?> <string>Some String</string> However, the 2nd and subsequent retrieve operations Message.Body is: "Cannot deserialize the message passed as an argument. Cannot recognize the serialization format." How does this work fine the first time but not after that? I have tried message.Dispose() after retrieving it but it did not help. Thank you very much for any help on this!

• Enumerating all strings in resx

  - by Erik Hesselink

  We would like to enumerate all strings in a resource file in .NET (resx file). We want this to generate a javascript object containing all these key-value pairs. We do this now for satellite assemblies with code like this (this is VB.NET, but any example code is fine): Dim rm As ResourceManager rm = New ResourceManager([resource name], [your assembly]) Dim Rs As ResourceSet Rs = rm.GetResourceSet(Thread.CurrentThread.CurrentCulture, True, True) For Each Kvp As DictionaryEntry In Rs [Write out Kvp.Key and Kvp.Value] Next However, we haven't found a way to do this for .resx files yet, sadly. How can we enumerate all localization strings in a resx file? UPDATE: Following Dennis Myren's comment and the ideas from here, I built a ResXResourceManager. Now I can do the same with .resx files as I did with the embedded resources. Here is the code. Note that Microsoft made a needed constructor private, so I use reflection to access it.

• Binding Data to DataGridView in VB.Net

  - by Peter

  Hi, I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine. What i want is for the code that connects / loads the data to sit in my Database Class and then everything associated with the datagridview to be stored in my Form but i am having problems passing the contents of the bindingsource over to the Form from the Database Class. Form1 Public Class Form1 Dim myDatabaseObj As New Class1() Dim bindingSource1 As New BindingSource() Dim connectString As New SqlConnection Dim objDataAdapter As New SqlDataAdapter Dim table As New DataTable() Dim tabletest As New DataTable() Private Sub loadCompanyList() Try Me.dgv_CompanyList.DataSource = Me.bindingSource1 getCompanyList() Catch ex As NullReferenceException End Try End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load loadCompanyList() End Sub End Class Database Class When i try place the getCompanyList() in a class and then create a new object that references the Form() it does not seem to return any value from the table to the MyForm.BindingSource1.Datasource meaning my datagridview displays not data. ..... Private Sub getCompanyList() Try Dim myForm as new Form() connect_Transaction_Database() objDataAdapter.SelectCommand = New SqlCommand() objDataAdapter.SelectCommand.Connection = connectString objDataAdapter.SelectCommand.CommandText = "sp_GetCompanyList" objDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure Dim commandBuilder As New SqlCommandBuilder(Me.objDataAdapter) Dim table As New DataTable() table.Locale = System.Globalization.CultureInfo.InvariantCulture Me.objDataAdapter.Fill(table) **MyForm.bindingSource1.DataSource = table** Catch ex As DataException MsgBox(ex.Message) Catch ex As NullReferenceException MsgBox(ex.Message) End Try disconnect_Transaction_Database() End Sub If anyone could help. Thank you. Peter

• Give WPF design mode default objects

  - by Janko R

  In my application I have <Rectangle.Margin> <MultiBinding Converter="{StaticResource XYPosToThicknessConverter}"> <Binding Path="XPos"/> <Binding Path="YPos"/> </MultiBinding> </Rectangle.Margin> The Data Context is set during runtime. The application works, but the design window in VS does not show a preview but System.InvalidCastException. That’s why I added a default object in the XYPosToThicknessConverter which is ugly. class XYPosToThicknessConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { // stupid check to give the design window its default object. if (!(values[0] is IConvertible)) return new System.Windows.Thickness(3, 3, 0, 0); // useful code and exception throwing starts here // ... } } My Questions: What does VS/the process that builds the design window pass to XYPosToThicknessConverter and what is way to find it out by myself. How do I change my XAML code, so that the design window gets its default object and is this the best way to handle this problem? I’m using VS2010RC with Net4.0

• Change CulturalInfo after button click

  - by Bart

  i have multilingual asp.net site. there is masterpage and default.aspx in masterpage i put two buttons one to click when i want to change the language to english, second for polish. I want to change the language after click on these buttons (and all changes should appear automatically on the page) here is a code for both: protected void EnglishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "en-US"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } protected void PolishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "pl-PL"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } in default.aspx.cs i have InitializeCulture(): protected override void InitializeCulture() { HttpCookie cookie = Request.Cookies["CultureInfo"]; // if there is some value in cookie if (cookie != null && cookie.Value != null) { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cookie.Value); Thread.CurrentThread.CurrentUICulture = new CultureInfo(cookie.Value); } else // if none value has been sent by cookie, set default language { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("pl-PL"); Thread.CurrentThread.CurrentUICulture = new CultureInfo("pl-PL"); } base.InitializeCulture(); } i added resource files and in one label i show actual culture: Welcome.Text = "Culture: " + System.Globalization.CultureInfo.CurrentCulture.ToString(); the problem is that when i run this app and click e.g. english button (default language is polish), there is no effect. if i click it second time or press F5, the changes are applies and in the label is Culture: en-US. the same happens if i want to change language back to polish (it works after second click (or one click and refresh)). What am i doing wrong?

• How to determine if DataGridView contains uncommitted changes when bound to a SqlDataAdapter

  - by JYelton

  I have a form which contains a DataGridView, a BindingSource, a DataTable, and a SqlDataAdapter. I populate the grid and data bindings as follows: private BindingSource bindingSource = new BindingSource(); private DataTable table = new DataTable(); private SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM table ORDER BY id ASC;", ClassSql.SqlConn()); private void LoadData() { table.Clear(); dataGridView1.AutoGenerateColumns = false; dataGridView1.DataSource = bindingSource; SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter); table.Locale = System.Globalization.CultureInfo.InvariantCulture; dataAdapter.Fill(table); bindingSource.DataSource = table; } The user can then make changes to the data, and commit those changes or discard them by clicking either a save or cancel button, respectively. private void btnSave_Click(object sender, EventArgs e) { // save everything to the displays table dataAdapter.Update(table); } private void btnCancel_Click(object sender, EventArgs e) { // alert user if unsaved changes, otherwise close form } I would like to add a dialog if cancel is clicked that warns the user of unsaved changes, if unsaved changes exist. Question: How can I determine if the user has modified data in the DataGridView but not committed it to the database? Is there an easy way to compare the current DataGridView data to the last-retrieved query? (Note that there would not be any other threads or users altering data in SQL at the same time.)

• MVC 2 Data annotations problem

  - by Louzzzzzz

  Hi. Going mad now. I have a MVC solution that i've upgraded from MVC 1 to 2. It all works fine.... except the Validation! Here's some code: In the controller: using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Security.Principal; using System.Web; using System.Web.Mvc; using System.Web.Security; using System.Web.UI; using MF.Services.Authentication; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MF.Controllers { //basic viewmodel public class LogOnViewData { [Required] public string UserName { get; set; } [Required] public string Password { get; set; } } [HandleError] public class AccountController : Controller { [HttpPost] public ActionResult LogOn(LogOnViewData lvd, string returnUrl) { if (ModelState.IsValid) { //do stuff - IsValid is always true } } } } The ModelState is always valid. The model is being populated correctly however. Therefore, if I leave both username and password blank, and post the form the model state is still valid. Argh! Extra info: using structure map for IoD. Previously, before upgrading to MVC 2 was using the MS data annotation library so had this in my global.asax.cs: ModelBinders.Binders.DefaultBinder = new Microsoft.Web.Mvc.DataAnnotations.DataAnnotationsModelBinder(); Have removed that now. I'm sure i'm doing something really basic and wrong. If someone could point it out that would be marvellous. Cheers

• Get the value for a WPF binding

  - by Jose

  Ok, I didn't want a bunch of ICommands in my MVVM ViewModels so I decided to create a MarkupExtension for WPF that you feed it a string(the name of the method), and it gives you back an ICommand that executes the method. here's a snippet: public class MethodCall : MarkupExtension { public MethodCall(string methodName) { MethodName = methodName; CanExecute = "Can" + methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { Binding bin= new Binding { Converter = new MethodConverter(MethodName,CanExecute) }; return bin.ProvideValue(serviceProvider); } } public class MethodConverter : IValueConverter { string MethodName; public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { //Convert to ICommand ICommand cmd = ConvertToICommand(); if (cmd == null) Debug.WriteLine(string.Format("Could not bind to method 'MyMethod' on object",MethodName)); return cmd; } } It works great, except when the binding fails(e.g. you mistype). When you do this in xaml: {Binding MyPropertyName} you see in the output window whenever the binding fails. and it tells you the propertyName the Type name etc. The MethodConverter Class can tell you the name of the method that failed, but it can't tell you the source object type. Because the value will be null. I can't figure out how to store the source object type so for the following class public class MyClass { public void MyMethod() { } } and the following xaml: <Button Command={d:MethodCall MyMethod}>My Method</Button> It currently says: "Could not bind to method 'MyMethod' on object but I would like it to say: "Could not bind to method 'MyMethod' on object MyClass Any ideas?

• Best way to get a single value from a DataTable?

  - by PiersMyers

  I have a number of static classes that contain tables like this: using System; using System.Data; using System.Globalization; public static class TableFoo { private static readonly DataTable ItemTable; static TableFoo() { ItemTable = new DataTable("TableFoo") { Locale = CultureInfo.InvariantCulture }; ItemTable.Columns.Add("Id", typeof(int)); ItemTable.Columns["Id"].Unique = true; ItemTable.Columns.Add("Description", typeof(string)); ItemTable.Columns.Add("Data1", typeof(int)); ItemTable.Columns.Add("Data2", typeof(double)); ItemTable.Rows.Add(0, "Item 1", 1, 1.0); ItemTable.Rows.Add(1, "Item 2", 1, 1.0); ItemTable.Rows.Add(2, "Item 3", 2, 0.75); ItemTable.Rows.Add(3, "Item 4", 4, 0.25); ItemTable.Rows.Add(4, "Item 5", 1, 1.0); } public static DataTable GetItemTable() { return ItemTable; } public static int Data1(int id) { DataRow[] dr = ItemTable.Select("Id = " + id); if (dr.Length == 0) { throw new ArgumentOutOfRangeException("id", "Out of range."); } return (int)dr[0]["Data1"]; } public static double Data2(int id) { DataRow[] dr = ItemTable.Select("Id = " + id); if (dr.Length == 0) { throw new ArgumentOutOfRangeException("id", "Out of range."); } return (double)dr[0]["Data2"]; } } Is there a better way of writing the Data1 or Data2 methods that return a single value from a single row that matches the given id?

• Can this be done using LINQ/Lambda, C#3.0

  - by Newbie

  Objective: Generate dates based on Week Numbers Input: StartDate, WeekNumber Output: List of dates from the Week number specified till the StartDate i.e. If startdate is 23rd April, 2010 and the week number is 1, then the program should return the dates from 16th April, 2010 till the startddate. The function public List<DateTime> GetDates(DateTime startDate,int weeks) { List<DateTime> dt = new List<DateTime>(); int days = weeks * 7; DateTime endDate = startDate.AddDays(-days); TimeSpan ts = startDate.Subtract(endDate); for (int i = 0; i <= ts.Days; i++) { DateTime dt1 = endDate.AddDays(i); dt.Add(dt1); } return dt; } I am calling this function as DateTime StartDate = DateTime.ParseExact("20100423", "yyyyMMdd", System.Globalization.CultureInfo.InvariantCulture); List<DateTime> dtList = GetDates(StartDate, 1); The program is working fine. Question is using C# 3.0 feature like Linq, Lambda etc. can I rewrite the program. Why? Because I am learning linq and lambda and want to implement the same. But as of now the knowledge is not sufficient to do the same by myself. Thanks.

• Cross-platform iteration of Unicode string

  - by kizzx2

  I want to iterate each character of a Unicode string, treating each surrogate pair and combining character sequence as a single unit (one grapheme). Example The text "??????" is comprised of the code points: U+0928, U+092E, U+0938, U+094D, U+0924, U+0947, of which, U+0938 and U+0947 are combining marks. static void Main(string[] args) { const string s = "??????"; Console.WriteLine(s.Length); // Ouptuts "6" var l = 0; var e = System.Globalization.StringInfo.GetTextElementEnumerator(s); while(e.MoveNext()) l++; Console.WriteLine(l); // Outputs "4" } So there we have it in .NET. We also have Win32's CharNextW() #include <Windows.h> #include <iostream> #include <string> int main() { const wchar_t * s = L"??????"; std::cout << std::wstring(s).length() << std::endl; // Gives "6" int l = 0; while(CharNextW(s) != s) { s = CharNextW(s); ++l; } std::cout << l << std::endl; // Gives "4" return 0; } Question Both ways I know of are specific to Microsoft. Are there portable ways to do it? I heard about ICU but I couldn't find something related quickly (UnicodeString(s).length() still gives 6). Would be an acceptable answer to point to the related function/module in ICU. C++ doesn't have a notion of Unicode, so a lightweight cross-platform library for dealing with these issues would make an acceptable answer.
