• Release Notes for 5/18/2012

  Here are the notes for this week’s release: Pull Requests We’ve added the ability to see the snippets of code where a user commented inline in the discussion of pull requests. You can also add another line comment directly from the discussion area, rather than navigating to the code diff viewer. Note that there’s currently a known issue where the line associated with the comment isn’t being properly differentiated for existing pull requests (the line in the middle of each diff preview should be bolded). Apologies for the inconvenience! As part of this work, we also took some time to clean up our diff viewer UI to remove the dots and introduce a new color scheme where green is used for added lines. Bug Fixes Fixed an issue affecting the ability to assign pull requests. Fixed an issue where managing various team resources for a project was not working in Chrome or Firefox. Fixed an issue where a project’s RSS subscribe dialog popped up in the wrong place. Fixed an issue where editing wiki anchor links would insert extra characters, resulting in broken links. Fixed an issue where project logos did not display correctly when browsing the site with https in Chrome or Firefox. Fixed an issue where users could encounter errors when deleting remote Git branches. Fixed an issue affecting the ability of fork collaborators to push changes to the fork. Fixed an issue where the advanced work item filters would not persist when navigating through result pages. Fixed an issue where the issue tracker notifications link was not clickable in Chrome. Fixed an issue where pull request comments with line breaks would not be formatted properly when viewing the pull request. Other We upgraded our Git servers to version 1.7.10.1.

• knowing all available entity types

  - by plofplof

  I'm making a game where at some point the game will create enemies of random types. Each type of enemy available is defined on its own class derived from an enemy superclass. To do this, obviously the different types of enemies should be known. This is what I have thought of: Just make a list manually. Very simple to do, but I don't like it because I'll be adding more enemy types over time, so any time I add a new class I have to remember to update this (same if I remove an enemy). I would like some kind of auto-updating list. A completely component based system. There are no different classes for each enemy, but definitions of enemies in some file where all enemy types can be found. I really don't need that level of complexity for my game. I'm still using a component based model to some degree, but each Enemy type gets defined on its own class. Java Annotation processing. Give each enemy subclass an annotation like @EnemyType("whatever"), then code an annotation processor that writes in a file all available enemy types. Any time a new class is added the file gets updated after compilation.This gives me a feeling of failure even if its a good solution, it's very dependant on Java, so it means I cant think of a general design good for any kind of language. Also I think that this would be too much work for something so simple. I would like to see comments on these ideas and other possible solutions Thanks

• Web-Service: How much would you charge? [closed]

  - by jacksbox

  I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

• A new day has dawned in my SharePoint world.

  - by SPTales

  Until I started working with SharePoint, I never thought I would be blogging.  I am usually a pretty private individual, but this thing called the SharePoint community pulls you in and makes you feel like you should be a part of it, contributing to it and giving something back.  So here I am blogging for the first time – and so begins my tale. I started my work life as a Systems admin, but was given a chance to start working with SharePoint 2007 back in - ironically enough - January of 2007.  It has been downhill from there or uphill depending on your perspective!  I jumped in with both feet and haven’t looked back.  Lucky for me Microsoft gave us a new version to work with.  A new job a couple years ago gave me the chance to work with that new version.  Now I spend my days weaving a tale of SharePoint for a Sales based organization. So why this blog?  To give something back. I spend most days toggling between administration, InfoPath, Branding and design, HTML, JQuery, and XSLT depending on the need.  The blog will detail these projects and solutions as best I can.  Hopefully they will be of use to someone who may be trying to accomplish similar things, just as many of the blogs that I have referenced over the last 5 years have been a huge help and resource for me.

• Representing a world in memory

  - by user9993

  I'm attempting to write a chunk based map system for a game, where as the player moves around chunks are loaded/unloaded, so that the program doesn't run out of memory by having the whole map in memory. I have this part mostly working, however I've hit a wall regarding how to represent the contents of each chunk in memory because of my so far limited understanding of OOP languages. The design I have currently has a ChunkManager class that uses a .NET List type to store instances of Chunk classes. The "chunks" consist of "blocks". It's similar to a Minecraft style game. Inside the Chunk classes, I have some information such as the chunk's X/Y coordinate etc, and I also have a three dimensional array of Block objects. (Three dimensional because I need XYZ values) Here's the problem: The Block class has some basic properties, and I had planned on making different types of blocks inherit from this "base" class. So for example, I would have "StoneBlock", "WaterBlock" etc. So because I have blocks of many different types, I don't know how I would create an array with different object types in each cell. This is how I currently have the three dimensional array declared in my Chunk class: private Block[][][] ArrayOfBlocks; But obviously this will only accept Block objects, not any of the other classes that inherit from Block. How would I go about creating this? Or am I doing it completely wrong and there's a better way?

• Localization of Database Strings in .Net

  - by Aligned

  I have several database tables that have a description column that I need to display in the UI. .Net has .resx files that will help with the translation of the strings, when the Thread.CurrentCulture.UICulture is set, but I needed a custom approach for the strings that are stored in the database and not in the .resx files. Here’s my approach: 1. Create a resource file for each database table and put them in the /Resources/Database/ directory. 2. Create a method in LocalizationHelpers (GetLocalizedString) that will get the string from the table for English (which should be cached to avoid unneeded service/database calls) or the resx when not English. 3. All database tables need to have a ResxKey field that matches the key in the resx file. 4. By convention the resx file will have the same name as the database table, and the key the same as the database ResxKey.   - if there are multiple columns that need translation, then one ResxKey will be used and Name or Description appended. Here’s the method I’m using to pull the string: public static string GetLocalizedString(string resourceName, string resourceKey) { if (executingAssembly == null) { executingAssembly = Assembly.GetExecutingAssembly(); } ResourceManager manager = new ResourceManager(resourceName, executingAssembly); return manager.GetString(resourceKey); }

• For what purpose I can use c++ to increase my skills?

  - by user824981

  I want to learn new things. Initially I was a PHP programmer. Then I thought it was not enough. Then I started learning Java thing. It took me 3 months to learn. Java, J2EE, Spring, Hibernte, Spring Security, Spring Roo and many design patterns MVC and stuff like AOP, DI . I never knew that before but I got the idea what J2EE. After 3 months, I just made a simple page with Registration form integrated with Spring Security. I wanted to make one complete project in it but that was too much for me and I didn't want spend more time on it as then i need to host that as well so I left that. Then I started learning Python and made few sys admin scripts and then Django and now I am finishing a complete web app in Python. Now I want to learn C++, but before that I need to find out what i can do with it. Just like I know Python is very useful because I have my own servers so I can write scripting and websites so Python is good for me. But I am confused in which areas C++ can help me. I don't want to end up like I have with Java where either I have big projects or nothing for day to day use.

• Should I be worrying about limiting the number of textures in my game?

  - by Donutz

  I am working on a GUI in XNA 4.0 at the moment. (Before you point out that there are many GUIs already in existance, this is as much a learning exercise as a practical project). As you may know, controls and dialogs in Windows actually consist of a number of system-level windows. For instance, a dialog box may consist of a window for the whole dialog, a child window for the client area, another window (barely showing) for the frame, and so on. This makes detecting mouse hits and doing clipping relatively easy. I'd like to design my XNA GUI along the same lines, but using overlapping Textures instead of windows obviously. My question (yes, there's actually a question in this drivel) is: am I at risk of adversely affecting game performance and/or running low in resources if I get too nuts with the creating of many small textures? I haven't been able to find much information on how resource-tight the XNA environment actually is. I grew up in the days of 64K ram so I'm used to obsessing about resources and optimization. Anyway, any feedback appreciated.

• How do I get any number of links to space evenly? [migrated]

  - by Aerodynamo

  Alright, so here is the situation... Say I have a navbar for a site, and I allow users to change the number of links they want on this navbar. This means they could have 3, 5, 10, etc. What I want to do is make it so that if one link is up, it only takes up, say, 1/5th of the space on the navbar. If I weren't using borders, I might do something like: width: 18%; padding: 0 1%; However, I have two problems with this: 1) For 4 buttons, that's fine that it doesn't fill up the whole row. It would look ugly if the links were too wide... but when I have 6 or 7 buttons, it's got huge overflow! 2) Since I have borders, I can't use a percentage value for the borders or the widths, because I can't properly estimate how much of the percentage it will be. Now, I know I don't have to use percentage values, but what I would ideally prefer is that the first button is the smallest possible size necessary for all the other buttons to fit properly, meaning that if I have 950px and 6 links, the first link can be about 150px while the others are 160px... that's fine. I want all the other buttons on the navbar to be equally sized, regardless of how many links there are. I also need for it to accept a border... I figure the way to do this is to put a border in the nested div, so that way it doesn't effect the overall width of the button? This is all well and good, but I'm still plagued by the issue of not being able to design a dynamic site using the style I want if I can't get all the nav buttons to fit the width properly. Are there some js tricks I could use? I don't even know... Thanks

• Drupal site Instant Messaging [migrated]

  - by pthurmond

  I am trying to find a module or a standalone solution that I can turn into a module that will allow me to have an instant messaging system like Facebook does on a Drupal site that I am working on. I have never setup a chat system before. My particular requirements are rather stringent. It needs to be a solution where we host the chatting server (if one is needed separate from the website itself). It must use the site's login state (can't use an external system at all, that means no GTalk, Yahoo IM, or AIM). It also must be able to handle up to 1,000 users at any given time. I have looked through the Drupal community and I tried the DXMPP module, but it requires Jquery UI 1.8 and that doesn't work with all of the other things that my site uses (such as Homebox). We do have a Jabber server already setup and ready to go. Does anyone have any thoughts or options here? Thanks! EDIT: We are using Drupal 6.

• Separate update and render

  - by NSAddict

  I'm programming a simple Snake in Java. I'm a complete newbie when it comes to Java and Game Developing, so please bear with me ;) Until now, I have been using a UI thread, as well as a update-thread. The update thread just set the position, set the GameObjects, and so on. I didn't think much of concurrency, but now I've come to a problem. I wanted to modify the ArrayList<GameObject>, but it throws a java.util.ConcurrentModificationException. With a little research I found out that this happens because the two threads are trying to access the variables at the same time. But I didn't really find a way to prevent this. I thought about copying the array and swapping them out when the rendering is finished, but I would have to deep-copy them, which isn't really the best solution in my opinion. It probably eats up more CPU resources than a single-threaded game. Are there any other ways to prevent this? Thanks a lot for your help!

• Where do I read more about building an architecture like Google has? [on hold]

  - by user107148

  I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

• Licensing a website's code [on hold]

  - by RosiePea

  I just changed to a new contract that I want to use with all my future clients. I love this contract. It's in plain English, very readable, very understandable. It has this statement regarding ownership of the website after it's been paid for: After any outstanding balance for the project is paid, we will assign to you all copyrights in the graphical and visual elements of the design that we will create under the scope of this project. However, we will retain the copyright to all coding elements, but will provide you with a license for you to use these elements in the deliverables of this project. What is this license of which it speaks? I understand the concept: I maintain all rights to my code but allow them to use it in this particular website. That part's new in this contract, and I like it a lot. But now... what? I have to come up with a license to hand the client when the website is paid for. But which license? And do I physically (or electronically) give them something, a document kind of like the contract itself? I've been reading all about licenses all day today and I'm no closer to answering this question. Any words of advice out there?

• SharePoint 2010 - Access denied during ApplyWebConfigModifications()

  - by tcoalson

  I have SharePoint 2010 installed on a Windows Server 2008 R2 machine which is also hosting SQL Sever 2008 R2. I am attempting to deploy a solution that includes web parts in the 2010 environment that is working fine in MOSS 2007. The Web Part feature has a feature receiver that updates the web.config. When I try to activate the feature through the Site Collection Feature GUI, I receive an access denied message. I am logged on to the server and in SharePoint with the APP Pool account which is also a member of the domain administrator group, local administrator group and SharePoint Farm Admin group. This account is also dbo on SQL Server. This same feature activates fine using the stsadm command. I have dug into this issue at length and here is what I have found: Looking at the Microsoft assemblies in reflector, my error is coming from the SPWebApplication.ApplyWebConfigModifications() method. I can see the trace statements from SPWebConfigFileChanges.RemoveModificationsWebConfigXMLDocument and SPWebConfigFileChanges.ApplyModificationsWebConfigXMLDocument. The next line is a Save(str).

• Add collection or array to wpf resource dictionary

  - by Chris Cap

  I've search high and low and can't find an answer to this. I have two questions How do you create an array or collection in XAML. I've got an array I want to stick in there and bind to a combo box. My first idea was to put an ItemsControl in a resource dictionary, but the ItemsSource of a combo box expects IEnumerable so that didn't work. Here's what I've tried in my resource dictionary and neither works <ItemsControl x:Key="stateList"> <sys:String>AL</sys:String> <sys:String>CA</sys:String> <sys:String>CN</sys:String> </ItemsControl> <ItemsControl x:Key="stateList2"> <ComboBoxItem>AL</ComboBoxItem> <ComboBoxItem>CA</ComboBoxItem> <ComboBoxItem>CN</ComboBoxItem> </ItemsControl> and here's how I bind to it <ComboBox SelectedValue="{Binding Path=State}" ItemsSource="{Binding Source={StaticResource stateList2}}" > </ComboBox> EDIT: UPDATED I got this first part to work this way <col:ArrayList x:Key="stateList3"> <sys:String>AL</sys:String> <sys:String>CA</sys:String> <sys:String>CN</sys:String> </col:ArrayList> However, I'd rather not use an array list, I'd like to use a generic list so if anyone knows how please let me know. EDIT UPDATE: I guess XAML has very limited support for generics so maybe an array list is the best I can do for now, but I would still like help on the second question if anyone has an anser 2nd. I've tried referencing a merged resource dictionary in my XAML and had problems because under Window.resources I had more than just the dictionary so it required me to add x:Key. Once I add the key, the system can no longer find the items in my resource dictionary. I had to move the merged dictionary to Grid.Resources instead. Ideally I'd like to reference the merged dictionary in the app.xaml but I have the same problem Here's some sample code. This first part required an x:key to compile because I have converter and it complained that every item must have a key if there is more than one <UserControl.Resources> <win:BooleanToVisibilityConverter x:Key="VisibilityConverter" /> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/ResourcesD.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </UserControl.Resources> I had to change it to this <UI:BaseStep.Resources> <win:BooleanToVisibilityConverter x:Key="VisibilityConverter" /> </UI:BaseStep.Resources> <Grid> <Grid.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/ResourcesD.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Grid.Resources> </Grid> Thank you

• MSBuild: TlbImp error since upgrading to VS 2010

  - by floele

  Hi, since upgrading my project to VS2010, including the use of MSBuild v4 instead of 3.5 (and not making any other changes), I get the following build error and have no clue how to fix it (log from CC.NET): <target name="ResolveComReferences" success="false"> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\NMSDVDXU.dll /namespace:NMSDVDXLib /machine:X64 /out:obj\x64\Release\Interop.NMSDVDXLib.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "NMSDVDXLib" wurde nicht gefunden.]]></warning> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\StarBurnX12.dll /namespace:RocketDivision.StarBurnX /machine:X64 /out:obj\x64\Release\Interop.RocketDivision.StarBurnX.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "RocketDivision.StarBurnX" wurde nicht gefunden.]]></warning> </target> Problem: A single valid machine type compatible with the input type library must be specified. It only applies to the x64 build of my project, x86 still works fine. Apparently, it tries to build a x64 interop assembly from the x86 DLL located in "C:\Assemblies". When executing the TlbImp command with the x64 DLL which is located in a different directory, it works fine. However, I don't know how I can configure my project to use different COM references for the x86 and x64 build. The OS on which the project is being compiled is WinXP x86. Building worked fine when using VS2005 + MSBuild 3.5 Any help would be highly appreciated. I tried building the upgraded project with MSBuild v3.5, but that doesn't work either. It complains about unknown NoWarn codes (probably new in 4.0).

• MSChart on ASP.NET MVC 2

  - by Adron

  I upgraded my MVC Application using MSChart to MVC 2 and have ended up with broken image links for the charts. See my blog entry here: http://blog.adronbhall.com/post/2010/04/12/MVC-2-Breaks-my-Charts.aspx I get no build errors anymore, and have completed the following steps. First, I setup the following web.config lines. add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" and add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" (NOTE: I took the chevrons off so the lines would appear) The next thing I did was create this page with the following code. Which should, according to it working in MVC<1, showed 4 charts. <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <%@ Import Namespace="Scorecard.Views" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Scorecard </asp:Content> <asp:Content ID="applicationTitle" ContentPlaceHolderID="ContentPlaceHolderApplicationName" runat="server"> <%=Html.Encode(ViewData["ApplicationTitle"])%> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <form id="form1" runat="server"> <h2> Web Analysis Scorecard </h2> <table> <tr> <td> <% ChartHelper chartHelper = new ChartHelper("Top Countries", (double[])ViewData["TopCountryCounts"], (string[])ViewData["TopCountries"], SeriesChartType.Pie); Chart chartPieTwo = chartHelper.ResultingChart; // Explode data point with label "USA" chartPieTwo.Series["DefaultSeries"].Points[3]["Exploded"] = "true"; chartHelper.RenderChart(this); %> </td> <td> <% chartHelper = new ChartHelper("View Cart Trend", (double[])ViewData["LineValues"], (string[])ViewData["TopEngines"], SeriesChartType.Line); chartHelper.RenderChart(this); %> </td> </tr> <tr> <td> <% chartHelper = new ChartHelper("Yesterday's Page Views", (double[])ViewData["ColumnStats"], (string[])ViewData["ColumnStatHeaders"], SeriesChartType.Column); chartHelper.RenderChart(this); %> </td> <td> <% double[] theValues = (double[])ViewData["ColumnStats"]; double[] newValues = new double[] { 0, 0, 0, 0 }; int count = 0; int daysInMonth = DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month); foreach (double d in theValues) { newValues[count] += d * daysInMonth; count++; } chartHelper = new ChartHelper("Current Month Page Views", newValues, (string[])ViewData["ColumnStatHeaders"], SeriesChartType.Bar); chartHelper.RenderChart(this); %> </td> </tr> </table> </form>

• How to change the data in Telerik's RadGrid based on Calendar's selected dates?

  - by Jronny

  I was creating another usercontrol with Telerik's RadGrid and Calendar. <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> <table class="style1"> <tr> <td>From</td> <td>To</td> </tr> <tr> <td><asp:Calendar ID="Calendar1" runat="server" SelectionMode="Day"></asp:Calendar></td> <td><asp:Calendar ID="Calendar2" runat="server" SelectionMode="Day"></asp:Calendar></td> </tr> <tr> <td><asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /></td> <td><asp:Button ID="btnClear" runat="server" Text="Clear" OnClick="btnClear_Click" /></td> </tr> </table> <telerik:RadGrid ID="RadGrid1" runat="server"> <MasterTableView CommandItemDisplay="Top"></MasterTableView> </telerik:RadGrid> and I am using Linq in code-behind: Entities1 entities = new Entities1(); public static object DataSource = null; protected void Page_Load(object sender, EventArgs e) { if (DataSource == null) { DataSource = (from entity in entities.nsc_moneytransaction select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }).OrderByDescending(a => a.date); } BindData(); } public void BindData() { RadGrid1.DataSource = DataSource; } protected void btnSubmit_Click(object sender, EventArgs e) { DateTime startdate = new DateTime(); DateTime enddatedate = new DateTime(); if (Calendar1.SelectedDate != null && Calendar2.SelectedDate != null) { startdate = Calendar1.SelectedDate; enddatedate = Calendar2.SelectedDate; var queryDateRange = from entity in entities.nsc_moneytransaction where DateTime.Parse(entity.transaction_date.Value.ToShortDateString()) >= DateTime.Parse(startdate.ToShortDateString()) && DateTime.Parse(entity.transaction_date.Value.ToShortDateString()) <= DateTime.Parse(enddatedate.ToShortDateString()) select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }; DataSource = queryDateRange.OrderByDescending(a => a.date); } else if (Calendar1.SelectedDate != null) { startdate = Calendar1.SelectedDate; var querySetDate = from entity in entities.nsc_moneytransaction where entity.transaction_date.Value == startdate select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }; DataSource = querySetDate.OrderByDescending(a => a.date); ; } BindData(); } protected void btnClear_Click(object sender, EventArgs e) { Calendar1.SelectedDates.Clear(); Calendar2.SelectedDates.Clear(); } The problems are, (1) when I click the submit button. the data in the RadGrid is not changed. (2) how can we check if there is nothing selected in the Calendar controls, because there is a date (01/01/0001) set even if we do not select anything from that calendar, thus Calendar1.SelectedDate != null is not enough. =( Thanks.

• window.focus() not working in Google Chrome

  - by nickyt

  Hey folks, Just wondering if Google Chrome is going to support window.focus() at some point. When I mean support, I mean have it work. The call to it doesn't fail, it just doesn't do anything. All other major browsers do not have this problem: FireFox, IE6-IE8 and Safari. I have a client-side class for managing browser windows. When I first create a window the window comes into focus, but subsequent attempts to bring focus to the window do not work. From what I can tell, this appears to be a security feature to avoid annoying pop-ups and it does not appear to be a WebKit issue as it works in Safari. I know one idea someone brought forward was to close the window then reopen it, but this is a horrible solution. Googling shows that I do not appear to be the only person frustrated with this. And just to be 100% clear, I mean new windows, not tabs (tabs cannot be focused from what I've read) and all the windows being opened are in the same domain. Any ideas? MyCompany = { UI: {} }; // Put this here if you want to test the code. I create these namespaces elsewhere in code. MyCompany.UI.Window = new function() { // Private fields var that = this; var windowHandles = {}; // Public Members this.windowExists = function(windowTarget) { return windowTarget && windowHandles[windowTarget] && !windowHandles[windowTarget].closed; } this.open = function(url, windowTarget, windowProperties) { // See if we have a window handle and if it's closed or not. if (that.windowExists(windowTarget)) { // We still have our window object so let's check if the URLs is the same as the one we're trying to load. var currentLocation = windowHandles[windowTarget].location; if ( ( /^http(?:s?):/.test(url) && currentLocation.href !== url ) || ( // This check is required because the URL might be the same, but absolute, // e.g. /Default.aspx ... instead of http://localhost/Default.aspx ... !/^http(?:s?):/.test(url) && (currentLocation.pathname + currentLocation.search + currentLocation.hash) !== url ) ) { // Not the same URL, so load the new one. windowHandles[windowTarget].location = url; } // Give focus to the window. This works in IE 6/7/8, FireFox, Safari but not Chrome. // Well in Chrome it works the first time, but subsequent focus attempts fail,. I believe this is a security feature in Chrome to avoid annoying popups. windowHandles[windowTarget].focus(); } else { // Need to do this so that tabbed browsers (pretty much all browsers except IE6) actually open a new window // as opposed to a tab. By specifying at least one window property, we're guaranteed to have a new window created instead // of a tab. windowProperties = windowProperties || 'menubar=yes,location=yes,width=700, height=400, scrollbars=yes, resizable= yes'; windowTarget = windowTarget || "_blank"; // Create a new window. var windowHandle = windowProperties ? window.open(url, windowTarget, windowProperties) : window.open(url, windowTarget); if (null === windowHandle) { alert("You have a popup blocker enabled. Please allow popups for " + location.protocol + "//" + location.host); } else { if ("_blank" !== windowTarget) { // Store the window handle for reuse if a handle was specified. windowHandles[windowTarget] = windowHandle; windowHandles[windowTarget].focus(); } } } } }

• How to configure a GridView CommandField to trigger Full Page Update in UpdatePanel

  - by Frinavale

  I have 2 user controls on my page. One is used for searching, and the other is used for editing (along with a few other things). The user control that provides the search functionality uses a GridView to display the search results. This GridView has a CommandField used for editing (showEditButton="true"). I would like to place the GridView into an UpdatePanel so that paging through the search results will be smooth. The thing is that when the user clicks the Edit Link (the CommandField) I need to preform a full page postback so that the search user control can be hidden and the edit user control can be displayed. Edit: the reason I need to do a full page postback is because the edit user control is outside of the UpdatePanel that my GridView is in. It is not only outside the UpdatePanel, but it's in a completely different user control. I have no idea how to add the CommandField as a full page postback trigger to the UpdatePanel. The PostBackTrigger (which is used to indicate the controls cause a full page postback) takes a ControlID as a parameter; however the CommandButton does not have an ID...and you can see why I'm having a problem with this. Update on what else I've tried to solve the problem: I took a new approach to solving the problem. In my new approach, I used a TemplateField instead of a CommandField. I placed a LinkButton control in the TemplateField and gave it a name. During the GridView's RowDataBound event I retrieved the LinkButton control and added it to the UpdatePanel's Triggers. This is the ASP Markup for the UpdatePanel and the GridView <asp:UpdatePanel ID="SearchResultsUpdateSection" runat="server"> <ContentTemplate> <asp:GridView ID="SearchResultsGrid" runat="server" AllowPaging="true" AutoGenerateColumns="false"> <Columns> <asp:TemplateField> <HeaderTemplate></HeaderTemplate> <ItemTemplate> <asp:LinkButton ID="Edit" runat="server" Text="Edit"></asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField ...... </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel> In my VB.NET code. I implemented a function that handles the GridView's RowDataBound event. In this method I find the LinkButton for the row being bound to, create a PostBackTrigger for the LinkButton, and add it to the UpdatePanel's Triggers. This means that a PostBackTrigger is created for every "edit" LinkButton in the GridView Edit: this did not create a PostBackTrigger for Every "edit" LinkButton because the ID is the same for all LinkButtons in the GridView. Private Sub SearchResultsGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles SearchResultsGrod.RowDataBound If e.Row.RowType = DataControlRowType.Header Then ''I am doing stuff here that does not pertain to the problem Else Dim editLink As LinkButton = CType(e.Row.FindControl("Edit"), LinkButton) If editLink IsNot Nothing Then Dim fullPageTrigger As New PostBackTrigger fullPageTrigger.ControlID = editLink.ID SearchResultsUpdateSection.Triggers.Add(fullPageTrigger) End If End If End Sub And instead of handling the GridView's RowEditing event for editing purposes i use the RowCommand instead. Private Sub SearchResultsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles SearchResultsGrid.RowCommand RaiseEvent EditRecord(Me, New EventArgs()) End Sub This new approach didn't work at all because all of the LinkButtons in the GridView have the same ID. After reading the MSDN article on the UpdatePanel.Triggers Property I have the impression that Triggers can only be defined declaratively. This would mean that anything I did in the VB code wouldn't work. Any advise would be greatly appreciated. Thanks, -Frinny

• How to get selected values from a dynamically created DropDownList Array after PostBack (Button Click)

  - by user739280

  I have a CheckBoxList that contains Employee Names on a Wizard Step. When employees are selected and the active step is changed, the Wizard1_ActiveStepChanged function is called and it dynamically creates a DropDownList Array for each employee that is selected. Each DropDownList specifies a condition of the employee. The DropDownList is created properly. When the user clicks submit, the DropDownList array is deleted and no selected values can be pulled from the array. I understand this is an issue with the PostBack and can be fixed with ViewState, but I am trying to figure out what I can do to fix it. ViewState is enabled for the checkboxlist and the DropDownList. This is what I have in the body of my System.Web.UI.Page class private int empcount; private DropDownList[] DDL_Emp { get { return (DropDownList[])ViewState["DDL_Emp"]; } set { ViewState["DDL_Emp"] = value; } } The relevant code: protected void Wizard1_ActiveStepChanged(object sender, EventArgs e) { if (Request.QueryString["type"] == "Accident" && BulletedList1.Items.Count > 0) { this.empcount = 0; for (int i = 0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { this.empcount++; } } if(this.empcount > 0) { this.DDL_Emp = new DropDownList[this.empcount]; for (int i = 0, j=0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { List<ListItem> cond = new List<ListItem>(); cond.Add(new ListItem("Disabled", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Diseased - Fatality", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Short Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Long Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Back to Work", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Relocated", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Transferred", CBL_EmpInvolved.Items[i].Value)); this.DDL_Emp[j] = new DropDownList(); this.DDL_Emp[j].ID = "DD_LabCondition_" + CBL_EmpInvolved.Items[i].Value; this.DDL_Emp[j].EnableViewState = true; this.DDL_Emp[j].Visible = true; this.DDL_Emp[j].Items.AddRange(cond.ToArray()); this.DDL_Emp[j].Items.Insert(0, new ListItem("-- Select condition of employee: " + CBL_EmpInvolved.Items[i].Text, "")); PH_LabCondition.Controls.Add(this.DDL_Emp[j]); j++; } } PH_LabCondition.Visible = true; MV_LabCondition.Visible = true; Label1_ReportTitle.Text += "Control Count: " + PH_LabCondition.Controls.Count.ToString(); } MV_LabCondition.ActiveViewIndex = 1; MV_LostTime.ActiveViewIndex = 1; } } This code is giving me the following error now: Type 'System.Web.UI.WebControls.DropDownList' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable. I've tried changing buttons to images, playing with the AutoPostBack feature. I'm lost on how to get my dropdownlist array saved to the ViewState and accessing it after the postback.

• Summer Programming Plans

  - by Gabe

  I've wanted to start "hacking" for many months now. But I put it off in favor of school and other things. Now, though, I'm free for the summer and want to learn as much as I can. I have a rough idea of what I want to try my hand at, but need some guidance as to what specifically - and how - I should learn. This is my plan so far: 1) Get good at programming in general. I plan to read up on how to think/work like a programmer. I'm waiting for the Pragmatic Programmer to arrive, which will be the first book I read. Q: What other books/ebooks should I look at? What more can I do here? 2) Learn/Improve at HTML/CSS. My first project will be to make a personal website/blog for myself using HTML and CSS. ----Then I hope to write/design articles like Dustin Curtis. After I finish this (and learn a programming language) I'll try to create user-based a user-focused website. Q: It's my understanding that just trying to design/manage websites is a good way to learn/improve at HTML/CSS. Is that all correct? 3) Try music development. This might be a sort of stretch for stackoverflow, but I'm interested in mixing/making techno songs. (Think Justice, or Daft Punk, or MSTRKRFT.) Q: I have a Mac. Any ideas on how I could start/learn music making? Any programs I should download, for instance? 4) My main goal: Learning a web development language/framework. I'm a year into learning/using C++. But what I really want to do is develop websites and web apps. I've searched online, and there seems to be great debate over which language/framework to learn first (and which is best). I think I've narrowed it down to three: Ruby (Rails), Python (Django), and PHP (?). Q #1: Which should I learn and use first? (Reasons?) Q #2: One reason I was leaning towards PHP is that I'm taking a PHP development course next semester. Learning it now would make that course easy. If PHP was not the answer to Q #1, is it worth learning both? Or, would it be better to just focus on PHP for this summer and next semester, and then transition thereafter to a better language? 5) iPhone/iPad Programming (Maybe). I've a number of simple, useful app ideas that I'd like to eventually get too. I just bought a Mac, as well as a few app development books. Q #1: Am I spreading myself thin trying to learn all of the above, and objective-C? Q #2: How much harder/easier is objective-C compared to the above languages? Also, how easy is it to learn obj-C after learning a web development language (and some C++)? Q #3: Yes or no? Should I go for it, or just keeep with #1-4 for now? Also: If you have any tips on how I should learn (or how you learned to hack), I'm all ears. I'd be especially interested in how you planned out learning: did you just hack whenever you felt like it, or did you "study" the language a few hours a day, or something else? Thanks so much, guys.
