  • Team Foundation Server 2012 Build Global List Problems

    - by Bob Hardister
    My experience with the upgrade and use of TFS 2012 has been very positive. I did come across a couple of issues recently that tripped things up for a while. ISSUE 1 The first issue is that 2012 prior to Update 1 published an invalid build list item value to the collection global list. In 2010, the build global list, list item value syntax is an underscore between the build definition and the build number. In the 2012 RTM this underscore was replaced with a backslash, which is invalid.  Specifically, an upload of the global list fails when the backslash is followed at some point by a period. The error when using the API is: <detail ExceptionMessage="TF26204: The account you entered is not recognized. Contact your Team Foundation Server administrator to add your account." BaseExceptionName="Microsoft.TeamFoundation.WorkItemTracking.Server.ValidationException"><details id="600019" http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03"http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03" /></detail> when uploading the global list via the process editor the error is: This issue is corrected in Update1 as the backslash is changed to a forward slash. ISSUE 2 The second issue is that when upgrading from 2010 to 2012, the builds in 2010 are not published to the 2012 global list.  After the upgrade the 2012 global lists doesn’t have any builds and only builds run in 2012 are published to the global list. This was reported to the MSDN forums and Connect. To correct this I wrote a utility to pull all the builds and recreate the builds global list for each project in each collection.  This is a console application with a program.cs, a globallists.cs and a app.config (not published here). The utility connects to TFS 2012, loops through the collections or a target collection as specified in the app.config. Then loops through the projects, the build definitions, and builds.  It creates a global list for each project if that project has at least one build. Then it imports the new list to TFS.  Here’s the code for program and globalists classes. Program.CS using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common; using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Server; using System.IO; using System.Xml; using Microsoft.TeamFoundation.WorkItemTracking.Client; using System.Diagnostics; using Utilities; using System.Configuration; namespace TFSProjectUpdater_CLC { class Program { static void Main(string[] args) { DateTime temp_d = System.DateTime.Now; string logName = temp_d.ToShortDateString(); logName = logName.Replace("/", "_"); logName = logName + "_" + temp_d.TimeOfDay; logName = logName.Replace(":", "."); logName = "TFSGlobalListBuildsUpdater_" + logName + ".log"; Trace.Listeners.Add(new TextWriterTraceListener(Path.Combine(ConfigurationManager.AppSettings["logLocation"], logName))); Trace.AutoFlush = true; Trace.WriteLine("Start:" + DateTime.Now.ToString()); Console.WriteLine("Start:" + DateTime.Now.ToString()); string tfsServer = ConfigurationManager.AppSettings["TargetTFS"].ToString(); GlobalLists gl = new GlobalLists(); //replace this with the URL to your TFS instance.

  • C # - a variable using the Encrypt md5

    - by Guilherme Cardoso
    When we are dealing with more sensitive data and important as a keyword, it is not appropriate at all stores them in database without encrypting for security reasons.  For this we use MD5  MD5 is an algorithm that allow us to encript an string, but doesn't leave us desencrypt it (not sure if it is already possible, but at least I know there are many databases already having a record).  The method below will return us a variable encrypted with md5. For example: md5_encriptar (pontonetpt.com ");   The result will be: 34efe85d338075834ad41803eb08c0df This way we save tthese encrypted data into a database, and then to make comparisons we often use the method to compare with the records kept. public string md5_encrypt(string md5) { System.Security.Cryptography.MD5CryptoServiceProvider x = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] bs = System.Text.Encoding.UTF8.GetBytes(md5); bs = x.ComputeHash(bs); System.Text.StringBuilder s = new System.Text.StringBuilder(); foreach (byte b in bs) { s.Append(b.ToString("x2").ToLower()); } string password = s.ToString(); return password; }

  • How to get tilemap transparency color working with TiledLib's Demo implementation?

    - by Adam LaBranche
    So the problem I'm having is that when using Nick Gravelyn's tiledlib pipeline for reading and drawing tmx maps in XNA, the transparency color I set in Tiled's editor will work in the editor, but when I draw it the color that's supposed to become transparent still draws. The closest things to a solution that I've found are - 1) Change my sprite batch's BlendState to NonPremultiplied (found this in a buried Tweet). 2) Get the pixels that are supposed to be transparent at some point then Set them all to transparent. Solution 1 didn't work for me, and solution 2 seems hacky and not a very good way to approach this particular problem, especially since it looks like the custom pipeline processor reads in the transparent color and sets it to the color key for transparency according to the code, just something is going wrong somewhere. At least that's what it looks like the code is doing. TileSetContent.cs if (imageNode.Attributes["trans"] != null) { string color = imageNode.Attributes["trans"].Value; string r = color.Substring(0, 2); string g = color.Substring(2, 2); string b = color.Substring(4, 2); this.ColorKey = new Color((byte)Convert.ToInt32(r, 16), (byte)Convert.ToInt32(g, 16), (byte)Convert.ToInt32(b, 16)); } ... TiledHelpers.cs // build the asset as an external reference OpaqueDataDictionary data = new OpaqueDataDictionary(); data.Add("GenerateMipMaps", false); data.Add("ResizetoPowerOfTwo", false); data.Add("TextureFormat", TextureProcessorOutputFormat.Color); data.Add("ColorKeyEnabled", tileSet.ColorKey.HasValue); data.Add("ColorKeyColor", tileSet.ColorKey.HasValue ? tileSet.ColorKey.Value : Microsoft.Xna.Framework.Color.Magenta); tileSet.Texture = context.BuildAsset<Texture2DContent, Texture2DContent>( new ExternalReference<Texture2DContent>(path), null, data, null, asset); ... I can share more code as well if it helps to understand my problem. Thank you.

  • Building Publishing Pages in Code

    - by David Jacobus
    Originally posted on: http://geekswithblogs.net/djacobus/archive/2013/10/27/154478.aspxOne of the Mantras we developers try to follow: Ensure that the solution package we deliver to the client is complete.  We build Web Parts, Master Pages, Images, CSS files and other artifacts that we push to the client with a WSP (Solution Package) And then we have them finish the solution by building their site pages by adding the web parts to the site pages.       I am a proponent that we,  the developers,  should minimize this time consuming work and build these site pages in code.  I found a few blogs and some MSDN documentation but not really a complete solution that has all these artifacts working in one solution.   What I am will discuss and provide a solution for is a package that has: 1.  Master Page 2.  Page Layout 3.  Page Web Parts 4.  Site Pages   Most all done in code without the development team or the developers having to finish up the site building process spending a few hours or days completing the site!  I am not implying that in Development we do this. In fact,  we build these pages incrementally testing our web parts, etc. I am saying that the final action in our solution is that we take all these artifacts and add them to the site pages in code, the client then only needs to activate a few features and VIOLA their site appears!.  I had a project that had me build 8 pages like this as part of the solution.   In this blog post, I am taking a master page solution that I have called DJGreenMaster.  On My Office 365 Development Site it looks like this:     It is a generic master page for a SharePoint 2010 site Along with a three column layout.  Centered with a footer that uses a SharePoint List and Web Part for the footer links.  I use this master page a lot in my site development!  Easy to change the color and site logo with a little CSS.   I am going to add a few web parts for discussion purposes and then add these web parts to a site page in code.    Lets look at the solution package for DJ Green Master as that will be the basis project for building the site pages:   What you are seeing  is a complete solution to add a Master Page to a site collection which contains: 1.  Master Page Module which contains the Master Page and Page Layout 2.  The Footer Module to add the Footer Web Part 3.  Miscellaneous modules to add images, JQuery, CSS and subsite page 4.  3 features and two feature event receivers: a.  DJGreenCSS, used to add the master page CSS file to Style Sheet Library and an Event Receiver to check it in. b.  DJGreenMaster used to add the Master Page and Page Layout.  In an Event Receiver change the master page to DJGreenMaster , create the footer list and check the files in. c.  DJGreenMasterWebParts add the Footer Web Part to the site collection. I won’t go over the code for this as I will give it to you at the end of this blog post. I have discussed creating a list in code in a previous post.  So what we have is the basis to begin what is germane to this discussion.  I have the first two requirements completed.  I need now to add page web parts and the build the pages in code.  For the page web parts, I will use one downloaded from Codeplex which does not use a SharePoint custom list for simplicity:   Weather Web Part and another downloaded from MSDN which is a SharePoint Custom Calendar Web Part, I had to add some functionality to make the events color coded to exceed the built-in 10 overlays using JQuery!    Here is the solution with the added projects:     Here is a screen shot of the Weather Web Part Deployed:   Here is a screen shot of the Site Calendar with JQuery:     Okay, Now we get to the final item:  To create Publishing pages.   We need to add a feature receiver to the DJGreenMaster project I will name it DJSitePages and also add a Event Receiver:       We will build the page at the site collection level and all of the code necessary will be contained in the event receiver.   Added a reference to the Microsoft.SharePoint.Publishing.dll contained in the ISAPI folder of the 14 Hive.   First we will add some static methods from which we will call  in our Event Receiver:   1: private static void checkOut(string pagename, PublishingPage p) 2: { 3: if (p.Name.Equals(pagename, StringComparison.InvariantCultureIgnoreCase)) 4: { 5: 6: if (p.ListItem.File.CheckOutType == SPFile.SPCheckOutType.None) 7: { 8: p.CheckOut(); 9: } 10:   11: if (p.ListItem.File.CheckOutType == SPFile.SPCheckOutType.Online) 12: { 13: p.CheckIn("initial"); 14: p.CheckOut(); 15: } 16: } 17: } 18: private static void checkin(PublishingPage p,PublishingWeb pw) 19: { 20: SPFile publishFile = p.ListItem.File; 21:   22: if (publishFile.CheckOutType != SPFile.SPCheckOutType.None) 23: { 24:   25: publishFile.CheckIn( 26:   27: "CheckedIn"); 28:   29: publishFile.Publish( 30:   31: "published"); 32: } 33: // In case of content approval, approve the file need to add 34: //pulishing site 35: if (pw.PagesList.EnableModeration) 36: { 37: publishFile.Approve("Initial"); 38: } 39: publishFile.Update(); 40: }   In a Publishing Site, CheckIn and CheckOut  are required when dealing with pages in a publishing site.  Okay lets look at the Feature Activated Event Receiver: 1: public override void FeatureActivated(SPFeatureReceiverProperties properties) 2: { 3:   4:   5:   6: object oParent = properties.Feature.Parent; 7:   8:   9:   10: if (properties.Feature.Parent is SPWeb) 11: { 12:   13: currentWeb = (SPWeb)oParent; 14:   15: currentSite = currentWeb.Site; 16:   17: } 18:   19: else 20: { 21:   22: currentSite = (SPSite)oParent; 23:   24: currentWeb = currentSite.RootWeb; 25:   26: } 27: 28:   29: //create the publishing pages 30: CreatePublishingPage(currentWeb, "Home.aspx", "ThreeColumnLayout.aspx","Home"); 31: //CreatePublishingPage(currentWeb, "Dummy.aspx", "ThreeColumnLayout.aspx","Dummy"); 32: }     Basically we are calling the method Create Publishing Page with parameters:  Current Web, Name of the Page, The Page Layout, Title of the page.  Let’s look at the Create Publishing Page method:   1:   2: private void CreatePublishingPage(SPWeb site, string pageName, string pageLayoutName, string title) 3: { 4: PublishingSite pubSiteCollection = new PublishingSite(site.Site); 5: PublishingWeb pubSite = null; 6: if (pubSiteCollection != null) 7: { 8: // Assign an object to the pubSite variable 9: if (PublishingWeb.IsPublishingWeb(site)) 10: { 11: pubSite = PublishingWeb.GetPublishingWeb(site); 12: } 13: } 14: // Search for the page layout for creating the new page 15: PageLayout currentPageLayout = FindPageLayout(pubSiteCollection, pageLayoutName); 16: // Check or the Page Layout could be found in the collection 17: // if not (== null, return because the page has to be based on 18: // an excisting Page Layout 19: if (currentPageLayout == null) 20: { 21: return; 22: } 23:   24: 25: PublishingPageCollection pages = pubSite.GetPublishingPages(); 26: foreach (PublishingPage p in pages) 27: { 28: //The page allready exists 29: if ((p.Name == pageName)) return; 30:   31: } 32: 33:   34:   35: PublishingPage newPage = pages.Add(pageName, currentPageLayout); 36: newPage.Description = pageName.Replace(".aspx", ""); 37: // Here you can set some properties like: 38: newPage.IncludeInCurrentNavigation = true; 39: newPage.IncludeInGlobalNavigation = true; 40: newPage.Title = title; 41: 42: 43:   44:   45: 46:   47: //build the page 48:   49: 50: switch (pageName) 51: { 52: case "Homer.aspx": 53: checkOut("Courier.aspx", newPage); 54: BuildHomePage(site, newPage); 55: break; 56:   57:   58: default: 59: break; 60: } 61: // newPage.Update(); 62: //Now we can checkin the newly created page to the “pages” library 63: checkin(newPage, pubSite); 64: 65: 66: }     The narrative in what is going on here is: 1.  We need to find out if we are dealing with a Publishing Web.  2.  Get the Page Layout 3.  Create the Page in the pages list. 4.  Based on the page name we build that page.  (Here is where we can add all the methods to build multiple pages.) In the switch we call Build Home Page where all the work is done to add the web parts.  Prior to adding the web parts we need to add references to the two web part projects in the solution. using WeatherWebPart.WeatherWebPart; using CSSharePointCustomCalendar.CustomCalendarWebPart;   We can then reference them in the Build Home Page method.   Let’s look at Build Home Page: 1:   2: private static void BuildHomePage(SPWeb web, PublishingPage pubPage) 3: { 4: // build the pages 5: // Get the web part manager for each page and do the same code as below (copy and paste, change to the web parts for the page) 6: // Part Description 7: SPLimitedWebPartManager mgr = web.GetLimitedWebPartManager(web.Url + "/Pages/Home.aspx", System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared); 8: WeatherWebPart.WeatherWebPart.WeatherWebPart wwp = new WeatherWebPart.WeatherWebPart.WeatherWebPart() { ChromeType = PartChromeType.None, Title = "Todays Weather", AreaCode = "2504627" }; 9: //Dictionary<string, string> wwpDic= new Dictionary<string, string>(); 10: //wwpDic.Add("AreaCode", "2504627"); 11: //setWebPartProperties(wwp, "WeatherWebPart", wwpDic); 12:   13: // Add the web part to a pagelayout Web Part Zone 14: mgr.AddWebPart(wwp, "g_685594D193AA4BBFABEF2FB0C8A6C1DD", 1); 15:   16: CSSharePointCustomCalendar.CustomCalendarWebPart.CustomCalendarWebPart cwp = new CustomCalendarWebPart() { ChromeType = PartChromeType.None, Title = "Corporate Calendar", listName="CorporateCalendar" }; 17:   18: mgr.AddWebPart(cwp, "g_20CBAA1DF45949CDA5D351350462E4C6", 1); 19:   20:   21: pubPage.Update(); 22:   23: } Here is what we are doing: 1.  We got  a reference to the SharePoint Limited Web Part Manager and linked/referenced Home.aspx  2.  Instantiated the a new Weather Web Part and used the Manager to add it to the page in a web part zone identified by ID,  thus the need for a Page Layout where the developer knows the ID’s. 3.  Instantiated the Calendar Web Part and used the Manager to add it to the page. 4. We the called the Publishing Page update method. 5.  Lastly, the Create Publishing Page method checks in the page just created.   Here is a screen shot of the page right after a deploy!       Okay!  I know we could make a home page look much better!  However, I built this whole Integrated solution in less than a day with the caveat that the Green Master was already built!  So what am I saying?  Build you web parts, master pages, etc.  At the very end of the engagement build the pages.  The client will be very happy!  Here is the code for this solution Code

  • Inline Image in ASP.NET

    - by Ricardo Peres
    Inline images is a technique that, instead of referring to an external URL, includes all of the image’s content in the HTML itself, in the form of a Base64-encoded string. It avoids a second browser request, at the cost of making the HTML page slightly heavier and not using cache. Not all browsers support it, but current versions of IE, Firefox and Chrome do. In order to use inline images, you must write the img element’s src attribute like this: 1: <img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/ 2: /ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcpp 3: V0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7" 4: width="16" height="14" alt="embedded folder icon"/> The syntax is: data:[<mediatype>][;base64],<data> I developed a simple control that allows you to use inline images in your ASP.NET pages. Here it is: 1: public class InnerImage: Image 2: { 3: protected override void OnInit(EventArgs e) 4: { 5: String imagePath = this.Context.Server.MapPath(this.ImageUrl); 6: String extension = Path.GetExtension(imagePath).Substring(1); 7: Byte[] imageData = File.ReadAllBytes(imagePath); 8:  9: this.ImageUrl = String.Format("data:image/{0};base64,{1}", extension, Convert.ToBase64String(imageData)); 10:  11: base.OnInit(e); 12: } 13: } Simple, don’t you think?

  • Getting codebaseHQ SVN ChangeLog data in your application

    - by saifkhan
    I deploy apps via ClickOnce. After each deployment we have to review the changes made and send out an email to the users with the changes. What I decided now to do is to use CodebaseHQ’s API to access a project’s SVN repository and display the commit notes so some users who download new updates can check what was changed or updated in an app. This saves a heck of a lot of time, especially when your apps are in beta and you are making several changes daily based on feedback. You can read up on their API here Here is a sample on how to access the Repositories API from a windows app Public Sub GetLog() If String.IsNullOrEmpty(_url) Then Exit Sub Dim answer As String = String.Empty Dim myReq As HttpWebRequest = WebRequest.Create(_url) With myReq .Headers.Add("Authorization", String.Format("Basic {0}", Convert.ToBase64String(Encoding.ASCII.GetBytes("username:password")))) .ContentType = "application/xml" .Accept = "application/xml" .Method = "POST" End With Try Using response As HttpWebResponse = myReq.GetResponse() Using sr As New System.IO.StreamReader(response.GetResponseStream()) answer = sr.ReadToEnd() Dim doc As XDocument = XDocument.Parse(answer) Dim commits = From commit In doc.Descendants("commit") _ Select Message = commit.Element("message").Value, _ AuthorName = commit.Element("author-name").Value, _ AuthoredDate = DateTime.Parse(commit.Element("authored-at").Value).Date grdLogData.BeginUpdate() grdLogData.DataSource = commits.ToList() grdLogData.EndUpdate() End Using End Using Catch ex As Exception MsgBox(ex.Message) End Try End Sub

  • Context Sensitive JTable

    - by Geertjan
    Here's a plain old JTable on the NetBeans Platform. Whenever the toolbar button is clicked, information about the currently selected row is displayed in the status bar: Normally, the above would be achieved in NetBeans Platform applications via Nodes publishing their underlying business object when the selection changes. In this case, there are no Nodes at all. There's only a JTable and a DefaultTableModel, i.e., all pure Java Swing. So, how does it work? To follow the logic, it makes sense to create the example yourself, starting with the Stock object: public class Stock {     String name;     String desc;     public Stock() {     }     public Stock(String name, String desc) {         this.name = name;         this.desc = desc;     }     public String getDesc() {         return desc;     }     public String getName() {         return name;     }     public void setDesc(String desc) {         this.desc = desc;     }     public void setName(String name) {         this.name = name;     } } Next, create a new Window Component via the wizard and then rewrite the constructor as follows: public final class MyWindowTopComponent extends TopComponent {     private final InstanceContent ic = new InstanceContent();     public MyWindowTopComponent() {         initComponents();         //Statically create a few stocks,         //in reality these would come from a data source         //of some kind:         List<Stock> list = new ArrayList();         list.add(new Stock("AMZN", "Amazon"));         list.add(new Stock("BOUT", "About.com"));         list.add(new Stock("Something", "Something.com"));         //Create a JTable, passing the List above         //to a DefaultTableModel:         final JTable table = new JTable(StockTableModel (list));         //Whenever the mouse is clicked on the table,         //somehow construct a new Stock object //(or get it from the List above) and publish it:         table.addMouseListener(new MouseAdapter() {             @Override             public void mousePressed(MouseEvent e) {                 int selectedColumn = table.getSelectedColumn();                 int selectedRow = table.getSelectedRow();                 Stock s = new Stock();                 if (selectedColumn == 0) {                     s.setName(table.getModel().getValueAt(selectedRow, 0).toString());                     s.setDesc(table.getModel().getValueAt(selectedRow, 1).toString());                 } else {                     s.setName(table.getModel().getValueAt(selectedRow, 1).toString());                     s.setDesc(table.getModel().getValueAt(selectedRow, 0).toString());                 }                 ic.set(Collections.singleton(s), null);             }         });         JScrollPane scrollPane = new JScrollPane(table);         add(scrollPane, BorderLayout.CENTER);         //Put the dynamic InstanceContent into the Lookup:         associateLookup(new AbstractLookup(ic));     }     private DefaultTableModel StockTableModel (List<Stock> stockList) {         DefaultTableModel stockTableModel = new DefaultTableModel() {             @Override             public boolean isCellEditable(int row, int column) {                 return false;             }         };         Object[] columnNames = new Object[2];         columnNames[0] = "Symbol";         columnNames[1] = "Name";         stockTableModel.setColumnIdentifiers(columnNames);         Object[] rows = new Object[2];         ListIterator<Stock> stockListIterator = stockList.listIterator();         while (stockListIterator.hasNext()) {             Stock nextStock = stockListIterator.next();             rows[0] = nextStock.getName();             rows[1] = nextStock.getDesc();             stockTableModel.addRow(rows);         }         return stockTableModel;     }     ...     ...     ... And now, since you're publishing a new Stock object whenever the user clicks in the table, you can create loosely coupled Actions, like this: @ActionID(category = "Edit", id = "org.my.ui.ShowStockAction") @ActionRegistration(iconBase = "org/my/ui/Datasource.gif", displayName = "#CTL_ShowStockAction") @ActionReferences({     @ActionReference(path = "Menu/File", position = 1300),     @ActionReference(path = "Toolbars/File", position = 300) }) @Messages("CTL_ShowStockAction=Show Stock") public final class ShowStockAction implements ActionListener {     private final Stock context;     public ShowStockAction(Stock context) {         this.context = context;     }     @Override     public void actionPerformed(ActionEvent ev) {         StatusDisplayer.getDefault().setStatusText(context.getName() + " / " + context.getDesc());     } }

  • DI and hypothetical readonly setters in C#

    - by Luis Ferrao
    Sometimes I would like to declare a property like this: public string Name { get; readonly set; } I am wondering if anyone sees a reason why such a syntax shouldn't exist. I believe that because it is a subset of "get; private set;", it could only make code more robust. My feeling is that such setters would be extremely DI friendly, but of course I'm more interested in hearing your opinions than my own, so what do you think? I am aware of 'public readonly' fields, but those are not interface friendly so I don't even consider them. That said, I don't mind if you bring them up into the discussion Edit I realize reading the comments that perhaps my idea is a little confusing. The ultimate purpose of this new syntax would be to have an automatic property syntax that specifies that the backing private field should be readonly. Basically declaring a property using my hypothetical syntax public string Name { get; readonly set; } would be interpreted by C# as: private readonly string name; public string Name { get { return this.name; } } And the reason I say this would be DI friendly is because when we rely heavily on constructor injection, I believe it is good practice to declare our constructor injected fields as readonly.

  • Workaround: build FBX in XNA raise OutOfMemoryException

OS on my PC is Win x64,  so I “charge” devenv.exe by using editbin.exe utility – in the VS Command prompt I run following: editbin "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /LARGEADDRESSAWARE This command edits the image to indicate that the application can handle addresses larger than 2 gigabytes.

And if your model’s vertexbuffer size more than 64Mb (with Reach profile), that model can’t be built and raise an error.

  • Force Blank TextBox with ASP.Net MVC Html.TextBox

    - by Doug Lampe
    I recently ran into a problem with the following scenario: I have data with a parent/child data with a one-to-many relationship from the parent to the child. I want to be able to update parent and existing child data AND add a new child record all in a single post. I don't want to create a model just to store the new values. One of the things I LOVE about MVC is how flexible it is in dealing with posted data.  If you have data that isn't in your model, you can simply use the non-strongly-typed HTML helper extensions and pass the data into your actions as parameters or use the FormCollection.  I thought this would give me the solution I was looking for.  I simply used Html.TextBox("NewChildKey") and Html.TextBox("NewChildValue") and added parameters to my action to take the new values.  So here is what my action looked like: [HttpPost] public ActionResult EditParent(int? id, string newChildKey, string newChildValue, FormCollection forms) {     Model model = ModelDataHelper.GetModel(id ?? 0);     if (model != null)     {         if (TryUpdateModel(model))         {             if (ModelState.IsValid)             {                 model = ModelDataHelper.UpdateModel(model);             }             string[] keys = forms.GetValues("ChildKey");             string[] values = forms.GetValues("ChildValue");             ModelDataHelper.UpdateChildData(id ?? 0, keys, values);             ModelDataHelper.AddChildData(id ?? 0, newChildKey, newChildValue);             model = ModelDataHelper.GetModel(id ?? 0);         }        return View(report);     }    return new EmptyResult(); } The only problem with this is that MVC is TOO smart.  Even though I am not using a model to store the new child values, MVC still passes the values back to the text boxes via the model state.  The fix for this is simple but not necessarily obvious, simply remove the data from the model state before returning the view: ModelState.Remove("NewChildKey"); ModelState.Remove("NewChildValue"); Two lines of code to save a lot of headaches.

  • How to implement fast search on Azure Blob?

    - by Vicky
    I am done with writing the code to upload files (text files) to azure blob storage. Now I want to provide search based on text files content. For ex. If I search for "Hello" then the name of files that contains "Hello" words should appear in search result. Here my code to search class BlobSearch { static void Main(string[] args) { string searchText = "Hello"; CloudStorageAccount account = CloudStorageAccount.Parse(azureConString); CloudBlobClient blobClient = account.CreateCloudBlobClient(); CloudBlobContainer blobContainer = blobClient.GetContainerReference("MyBlobContainer"); blobContainer.FetchAttributes(); var blobItemList = blobContainer.ListBlobs(); foreach (var item in blobItemList) { string line = string.Empty; CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(item.Uri.ToString()); if(blockBlob.Name.Contains(".txt")) { int lineno = 1; using (var stream = blockBlob.OpenRead()) { using (StreamReader reader = new StreamReader(stream)) { while ((line = reader.ReadLine()) != null) { if (line.IndexOf(searchText) != -1) { Console.WriteLine("Line : " + lineno +" => "+ blockBlob.Name); } lineno++; } } } } } Console.WriteLine("SEARCH COMPLETE"); Console.ReadLine(); } } Above code is working but it is too slow. Is there any way to do it faster or Can improve above code.

  • C++ and function pointers assessment: lack of inspiration

    - by OlivierDofus
    I've got an assessment to give to my students. It's about C++ and function pointers. Their skill is middle: it the first year of a programming school after bachelor. To give you something precise, here's a sample of a solution of one of 3 exercices they had to do in 30 minutes (the question was: "here's a version of a code that could be written with function pointers, write down the same thing but with function pointers"): typedef void (*fcPtr) (istream &); fcPtr ArrayFct [] = { Delete , Insert, Swap, Move }; void HandleCmd (const string && Cmd) { string AvalaibleCommands ("DISM"); string::size_type Pos; istringstream Flux (Cmd); char CodeOp; Flux >> CodeOp; Pos = AvalaibleCommands.find (toupper (CodeOp)); if (Pos != string::npos) { ArrayFct [Pos](Flux); } } Any idea where I could find some inspiration? Some of the students have understood the principles, even though it's very hard for them to write C++ code. I know them, I know they're clever, and I'm pretty sure they should be very good project managers. So, writing C++ code is not that important after all. Understanding is the most important part (IMHO). I'm wondering about maybe break the habits, and give half of the questions about the principle, or even better, give some sample in other language and ask them why it's better to use function pointers instead of classical programming (usually a big switch case). Any idea where I could look? Find some inspiration?

  • How to let maas' cloud-init client select internal mirror?

    - by Michael
    Our maas lan can't access internet and have a internal apt-mirror site 192.168.3.6. I changed mirror set of maas server's snippets/maas_proxy file like: d-i mirror/country string manual d-i mirror/http/hostname string 192.168.3.6 d-i mirror/http/directory string /ubuntu d-i mirror/http/proxy string I deployed two maas node ok. Dashboard show the two node's state are ready. But node's cloud-init client changed the apt's sources.list like this: ## Note, this file is written by cloud-init on first boot of an instance ## modifications made here will not survive a re-bundle. ## if you wish to make changes you can: ## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg ## or do the same in user-data ... deb http://archive.ubuntu.com/ubuntu precise main deb-src http://archive.ubuntu.com/ubuntu precise main ... Directly use cobbler install node(without maas), the node apt's sources.list like: ... deb http://192.168.3.6/ubuntu precise main deb-src http://192.168.3.6/ubuntu precise main ... My question is: How to set user-data in maas? So that I can set cloud-init's mirror's url to 192.168.3.6 or prevent cloud-init to change mirror's url. Maas node's file /home/ubuntu/.ssh/authorized_keys is empty. Is it caused by the mirror's setup?

  • OOP concept: is it possible to update the class of an instantiated object?

    - by Federico
    I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

  • Referrer Strings

    - by WernerCD
    I'm not exactly sure how to ask this, but here I go. I work for a company that provides IT services. Our main costumer has a website developed by WebCompany.com, and I act as a maintainer/middle-man for this website for our customer. What's happening is that on the front page there is a drop-down-menu with links. One link goes to a third party website - ThirdParty.com. This third party website automatically logs you in based on your IP or your referrer string. Homepage ThirdParty.com Logged in via IP or referrer string. What's happening... is Website.com is passing along inconsistent referrer strings. I've asked them to look into it and they say it's not their fault, referrer strings are handled at the browser. ThirdParty.com is actually nice enough to have IP and referrer string listed on the front page for users not logged in. So... how can I trace the referrer string so that I can figure out why http://Website.com's front page link to ThirdParty.com is showing a referrer as "None" or "Thirdparty.com" instead of "ThirdParty.com"? Their website is build in PHP. Can you force all links on a website to list "referrer" as "http://website.com/"? instead of "http://website.com/portal/1" or "http://website.com/page3"?

  • Save password in WCF adapter binding file

    - by Edmund Zhao
    Binding file for WCF Adapter doesn't save the password no matter it is generated by "Add Generated Items..." wizard in Visual Studio or "Export Bindings..." in administration console. It is by design dut to the consideration of security, but it is very annoying especially when you import bindings which contain multiple WCF send ports. The way to aviod retyping password everytime after an import is to edit the binding file before import. Here is what needs to be done. 1. Find the following string:     &lt;Password vt="1" /&gt; "&lt;" means "<", "&gt;" means ">", "vt" means "Variable Type", variable type 1 is "NULL", so the above string can be translated to "<Password/>" 2. Replace it with:     &lt;Password vt="8"&gt;MyPassword&lt;/Password&gt;    variable type 8 is "string", the above string can be transalted to "<Password>MyPassword</Password>"   Binding file uses a lot of character entity references for XML character encoding purpose. For a list of the special charactor entiy references, you can check from here. ...Edmund Zhao

  • MVC Scaffold Template Not Generating?

    - by monkey9987
    Been working on an MVC project and my templates were not generating. I first created my Model inside my "Models" folder, then did a quick compile. Next I went to the Views folder to get it created, right click and say "Add View" then I clicked the checkbox to create an edit page. What happened was the template would never seem to pull in my Model, it would just have the default header items, but the entire model was missing.  My model was defined as follows: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName;[Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password;[Display(Name = "Remember me?")]public bool RememberMe; } See anything wrong with that? I couldn't figure out why each time I created my View and selected the option to create the "Edit" scaffold automatically, it would come up blank. Turns out I'm missing my get / set methods on the Model class items. Here's my code with the correct setup: public class LogOnModel { [Required][Display(Name = "User name")]public string UserName { get; set; } [Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password { get; set; }[Display(Name = "Remember me?")]public bool RememberMe { get; set; } }  I hope that helps someone out, it's pretty simple when I look at it now, but that's always the case!  ~ Steve

  • What are some Java patterns well-suited for fast, algorithmic coding?

    - by Casey Chu
    I'm in college, and I've recently started competing in programming competitions with my friends. These competitions involve solving algorithmic problems quickly. It's a lot of fun, but there's one problem: I'm forced to use Java. (My teammates use Java.) Background: I'm a self-taught JavaScript programmer, and it hurts to write Java code. I find it very verbose and inflexible, and I feel slowed down when having to declare types and decide which of the eighty list data structure to use. I'm also frustrated about the lack of functional programming features and how verbose using regular expressions, arrays, and dictionaries are. As an example, consider the problem of finding the length of the longest string of consecutive characters in a given string. So the string XX22BBBBccXX222 would give 4, for the string of four Bs. In Java, I'd have to loop through and manually count characters and manually keep track of the maximum. (That's at least as far as I'm aware -- I'm not as familiar with Java as I am with JavaScript.) In JavaScript, I'd find it like this: var max = Math.max.apply(Math, str.match(/(.)\1*/g).map(function (s) { return s.length; })); Much quicker and simpler, in my book. The question: what are some Java features, techniques, or patterns well-suited for fast, algorithmic coding?

  • Essbase - FormatString

    - by THE
    A look at the documentation for "Typed Measures" shows:"Using format strings, you can format the values (cell contents) of Essbase database members in numeric type measures so that they appear, for query purposes, as text, dates, or other types of predefined values. The resultant display value is the cell’s formatted value (FORMATTED_VALUE property in MDX). The underlying real value is numeric, and this value is unaffected by the associated formatted value."To actually switch ON the use of typed measures in general, you need to navigate to the outline properties: open outline select properties change "Typed Measures enable" to TRUE (click to enlarge) As an example, I created two additional members in the ASOSamp outline. - A member "delta Price" in the Measures (Accounts) Dimension with the Formula: ([Original Price],[Curr_year])-([Original Price],[Prev_year])This is equivalent to the Variance Formula used in the "Years" Dimension. - A member "Var_Quickview" in the "Years" Dimension with the same formula as the "Variance" Member.This will be used to simply display a second cell with the same underlying value as Variance - but formatted using Format String hence enabling BOTH in the same report. (click to enlarge) In the outline you now select the member you want the Format String associated with and change the "associated Format String" in the Member Properties.As you can see in this example an IIF statement reading:MdxFormat(IIF(CellValue()< 0,"Negative","Positive" ) ) has been chosen for both new members.After applying the Format String changes and running a report via SmartView, the result is: (click to enlarge) reference: Essbase Database Admin Guide ,Chapter 12 "Working with Typed Measures "

  • C++ Windows Forms application unhandled exception error when textbox empty

    - by cmorris1441
    I'm building a temperature conversion application in Visual Studio for a C++ course. It's a Windows Forms application and the code that I've written is below. There's other code to of course, but I'm not sure you need it to help me. My problem is, when I run the application if I don't have anything entered into either the txtFahrenheit or txtCelsius2 textboxes I get the following error: "An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll" The application only works right now when a number is entered into both of the textboxes. I was told to try and use this: Double::TryParse() but I'm brand new to C++ and can't figure out how to use it, even after checking the MSDN library. Here's my code: private: System::Void btnFtoC_Click(System::Object^ sender, System::EventArgs^ e) { // Convert the input in the Fahrenheit textbox to a double datatype named fahrenheit for manipulation double fahrenheit = Convert::ToDouble(txtFahrenheit->Text); // Set the result string to F * (5/9) -32 double result = fahrenheit * .5556 - 32; // Set the Celsius text box to display the result string txtCelsius->Text = result.ToString(); } private: System::Void btnCtoF_Click(System::Object^ sender, System::EventArgs^ e) { // Convert the input in the Celsius textbox to a double datatype name celsius for manipulation double celsius = Convert::ToDouble(txtCelsius2->Text); // Set the result2 string to C * (9/5) + 32 double result2 = celsius * 1.8 + 32; // Set the Fahrenheit text box to display the result2 string txtFahrenheit2->Text = result2.ToString(); }

  • What should a domain object's validation cover?

    - by MarcoR88
    I'm trying to figure out how to do validation of domain objects that need external resources, such as data mappers/dao Firstly here's my code class User { const INVALID_ID = 1; const INVALID_NAME = 2; const INVALID_EMAIL = 4; int getID(); void setID(Int i); string getName(); void setName(String s); string getEmail(); void setEmail(String s); int getErrorsForInsert(); // returns a bitmask for INVALID_* constants int getErrorsForUpdate(); } My worries are about the uniqueness of the email, checking it would require the storage layer. Reading others' code seems that two solutions are equally accepted: both perform the unique validation in data mapper but some set an error state to the DO user.addError(User.INVALID_EMAIL) while others prefer to throw a totally different type of exception that covers only persistence, like: UserStorageException { const INVALID_EMAIL = 1; const INVALID_CITY = 2; } What are the pros and cons of these solutions?

  • Implementing a ILogger interface to log data

    I have a need to write data to file in one of my classes. Obviously I will pass an interface into my class to decouple it. I was thinking this interface will be used for testing and also in other projects. This is my interface: //This could be used by filesystem, webservice public interface ILogger { List<string> PreviousLogRecords {get;set;} void Log(string Data); } public interface IFileLogger : ILogger { string FilePath; bool ValidFileName; } public class MyClassUnderTest { public MyClassUnderTest(IFileLogger logger) {....} } [Test] public void TestLogger() { var mock = new Mock<IFileLogger>(); mock.Setup(x => x.Log(Is.Any<string>).AddsDataToList()); //Is this possible?? var myClass = new MyClassUnderTest(mock.Object); myClass.DoSomethingThatWillSplitThisAndLog3Times("1,2,3"); Assert.AreEqual(3,mock.PreviousLogRecords.Count); } This won't work I don't believe as nothing is storing the items so is this possible using Moq and also what do you think of the design of the interface?

  • Question about a simple design problem

    - by Uri
    At work I stumbled uppon a method. It made a query, and returned a String based on the result of the query, such as de ID of a customer. If the query didn't return a single customer, it'd return a null. Otherwise, it'd return a String with the ID's of them. It looked like this: String error = getOwners(); if (error != null) { throw new Exception("Can't delete, the flat is owned by: " + error); } ... Ignoring the fact that getCustomers() returns a null when it should instead return an empty String, two things are happening here. It checks if the flat is owned by someone, and then returns them. I think a more readable logic would be to do this: if (isOwned) { throw new Exception("Can't delete, the flat is owned by: " + getOwners()); } ... The problem is that the first way does with one query what I do with two queries to the database. What would be a good solution involving good design and efficiency for this?

  • Faster, Simpler access to Azure Tables with Enzo Azure API

    - by Herve Roggero
    After developing the latest version of Enzo Cloud Backup I took the time to create an API that would simplify access to Azure Tables (the Enzo Azure API). At first, my goal was to make the code simpler compared to the Microsoft Azure SDK. But as it turns out it is also a little faster; and when using the specialized methods (the fetch strategies) it is much faster out of the box than the Microsoft SDK, unless you start creating complex parallel and resilient routines yourself. Last but not least, I decided to add a few extension methods that I think you will find attractive, such as the ability to transform a list of entities into a DataTable. So let’s review each area in more details. Simpler Code My first objective was to make the API much easier to use than the Azure SDK. I wanted to reduce the amount of code necessary to fetch entities, remove the code needed to add automatic retries and handle transient conditions, and give additional control, such as a way to cancel operations, obtain basic statistics on the calls, and control the maximum number of REST calls the API generates in an attempt to avoid throttling conditions in the first place (something you cannot do with the Azure SDK at this time). Strongly Typed Before diving into the code, the following examples rely on a strongly typed class called MyData. The way MyData is defined for the Azure SDK is similar to the Enzo Azure API, with the exception that they inherit from different classes. With the Azure SDK, classes that represent entities must inherit from TableServiceEntity, while classes with the Enzo Azure API must inherit from BaseAzureTable or implement a specific interface. // With the SDK public class MyData1 : TableServiceEntity {     public string Message { get; set; }     public string Level { get; set; }     public string Severity { get; set; } } //  With the Enzo Azure API public class MyData2 : BaseAzureTable {     public string Message { get; set; }     public string Level { get; set; }     public string Severity { get; set; } } Simpler Code Now that the classes representing an Azure Table entity are defined, let’s review the methods that the Azure SDK would look like when fetching all the entities from an Azure Table (note the use of a few variables: the _tableName variable stores the name of the Azure Table, and the ConnectionString property returns the connection string for the Storage Account containing the table): // With the Azure SDK public List<MyData1> FetchAllEntities() {      CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConnectionString);      CloudTableClient tableClient = storageAccount.CreateCloudTableClient();      TableServiceContext serviceContext = tableClient.GetDataServiceContext();      CloudTableQuery<MyData1> partitionQuery =         (from e in serviceContext.CreateQuery<MyData1>(_tableName)         select new MyData1()         {            PartitionKey = e.PartitionKey,            RowKey = e.RowKey,            Timestamp = e.Timestamp,            Message = e.Message,            Level = e.Level,            Severity = e.Severity            }).AsTableServiceQuery<MyData1>();        return partitionQuery.ToList();  } This code gives you automatic retries because the AsTableServiceQuery does that for you. Also, note that this method is strongly-typed because it is using LINQ. Although this doesn’t look like too much code at first glance, you are actually mapping the strongly-typed object manually. So for larger entities, with dozens of properties, your code will grow. And from a maintenance standpoint, when a new property is added, you may need to change the mapping code. You will also note that the mapping being performed is optional; it is desired when you want to retrieve specific properties of the entities (not all) to reduce the network traffic. If you do not specify the properties you want, all the properties will be returned; in this example we are returning the Message, Level and Severity properties (in addition to the required PartitionKey, RowKey and Timestamp). The Enzo Azure API does the mapping automatically and also handles automatic reties when fetching entities. The equivalent code to fetch all the entities (with the same three properties) from the same Azure Table looks like this: // With the Enzo Azure API public List<MyData2> FetchAllEntities() {        AzureTable at = new AzureTable(_accountName, _accountKey, _ssl, _tableName);        List<MyData2> res = at.Fetch<MyData2>("", "Message,Level,Severity");        return res; } As you can see, the Enzo Azure API returns the entities already strongly typed, so there is no need to map the output. Also, the Enzo Azure API makes it easy to specify the list of properties to return, and to specify a filter as well (no filter was provided in this example; the filter is passed as the first parameter).  Fetch Strategies Both approaches discussed above fetch the data sequentially. In addition to the linear/sequential fetch methods, the Enzo Azure API provides specific fetch strategies. Fetch strategies are designed to prepare a set of REST calls, executed in parallel, in a way that performs faster that if you were to fetch the data sequentially. For example, if the PartitionKey is a GUID string, you could prepare multiple calls, providing appropriate filters ([‘a’, ‘b’[, [‘b’, ‘c’[, [‘c’, ‘d[, …), and send those calls in parallel. As you can imagine, the code necessary to create these requests would be fairly large. With the Enzo Azure API, two strategies are provided out of the box: the GUID and List strategies. If you are interested in how these strategies work, see the Enzo Azure API Online Help. Here is an example code that performs parallel requests using the GUID strategy (which executes more than 2 t o3 times faster than the sequential methods discussed previously): public List<MyData2> FetchAllEntitiesGUID() {     AzureTable at = new AzureTable(_accountName, _accountKey, _ssl, _tableName);     List<MyData2> res = at.FetchWithGuid<MyData2>("", "Message,Level,Severity");     return res; } Faster Results With Sequential Fetch Methods Developing a faster API wasn’t a primary objective; but it appears that the performance tests performed with the Enzo Azure API deliver the data a little faster out of the box (5%-10% on average, and sometimes to up 50% faster) with the sequential fetch methods. Although the amount of data is the same regardless of the approach (and the REST calls are almost exactly identical), the object mapping approach is different. So it is likely that the slight performance increase is due to a lighter API. Using LINQ offers many advantages and tremendous flexibility; nevertheless when fetching data it seems that the Enzo Azure API delivers faster.  For example, the same code previously discussed delivered the following results when fetching 3,000 entities (about 1KB each). The average elapsed time shows that the Azure SDK returned the 3000 entities in about 5.9 seconds on average, while the Enzo Azure API took 4.2 seconds on average (39% improvement). With Fetch Strategies When using the fetch strategies we are no longer comparing apples to apples; the Azure SDK is not designed to implement fetch strategies out of the box, so you would need to code the strategies yourself. Nevertheless I wanted to provide out of the box capabilities, and as a result you see a test that returned about 10,000 entities (1KB each entity), and an average execution time over 5 runs. The Azure SDK implemented a sequential fetch while the Enzo Azure API implemented the List fetch strategy. The fetch strategy was 2.3 times faster. Note that the following test hit a limit on my network bandwidth quickly (3.56Mbps), so the results of the fetch strategy is significantly below what it could be with a higher bandwidth. Additional Methods The API wouldn’t be complete without support for a few important methods other than the fetch methods discussed previously. The Enzo Azure API offers these additional capabilities: - Support for batch updates, deletes and inserts - Conversion of entities to DataRow, and List<> to a DataTable - Extension methods for Delete, Merge, Update, Insert - Support for asynchronous calls and cancellation - Support for fetch statistics (total bytes, total REST calls, retries…) For more information, visit http://www.bluesyntax.net or go directly to the Enzo Azure API page (http://www.bluesyntax.net/EnzoAzureAPI.aspx).
