Yet another bug of JSF?

- by Nitesh Panchal

Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

Append <ul> and <li> in recursive loop

- by Batman

I have a site collection. I was told I need a recursive loop to do this. This is what I've tried: When the site loads, call getSiteTree() which passes the top level website to my getSubSite() function. From there I check if there are any subsites. I have a boolean but I'm not really using it for anything yet, I've just seen it used before for this type of work. Anyways, from there I check if there are any sub sits, if not I log the end of the branch, if there are, I call the function again using the new url and repeat the process. Looking at my console, it seems to work as intended. function getSiteTree(){ var tree = $('#treeviewList'); var rootsite = window.location.protocol + "//" + window.location.hostname; var siteEnd = false; getSubSite(rootsite); } function getSubSite(url){ $().SPServices({ operation: "GetWebCollection", webURL: url, async: true, completefunc: function(xData, Status) { var siteUrl; var siteCount = $(xData.responseXML).find("Web").length; if(siteCount == 0){ console.log("end of branch"); siteEnd = true; }else{ $(xData.responseXML).find("Web").each(function() { siteUrl = $(this).attr("Url"); console.log(siteUrl); getSubSite(siteUrl); }); } } }); } My questions: now that I have my sites, I need to take those sites and create something like this but I'm not sure how to accomplish this. <li>Site 1 <ul> <li>sub 1.1</li> <li>sub 1.2</li> <li>sub 1.3</li> <ul> <li>1.3.1</li> </ul> <li>sub 1.4</li> <li>sub 1.5</li> </ul> </li> <li>Site 2 <ul> <li>sub 2.1</li> <li>sub 2.2</li> <li>sub 2.3</li> <ul> <li>2.3.1</li> <li>2.3.2</li> </ul> </ul> </li> </ul> I have this inital html: <div id="treeviewDiv" style="width:200px;height:150px;overflow:scroll"> <ui id="treeviewList"></ui> </div>

ASP.NET MVC 3 embrace dynamic type - CSDN.NET - CSDN Software Development Channel

- by user559071

About a decade ago, Microsoft will all bet on the WebForms and static types. With the complete package from scattered to the continuous development, and now almost every page can be viewed as its own procedure. Subsequent years, the industry continued to move in another direction, love is better than separation package, better than the late binding early binding to the idea. This leads to two very interesting questions. The first is the problem of terminology. Consider the original Smalltalk MVC model, view and controller is not only tightly coupled together, and usually in pairs. Most of the framework is that Microsoft, including the classic VB, WinForms, WebForms, WPF and Silverlight, they both use the code behind file to store the controller logic. But said "MVC" usually refers to the view and controller are loosely coupled framework. This is especially true for the Web framework, HTML form submission mechanism allows any views submitted to any of the controller. Since this article was mainly talking about Web technologies, so we need to use the modern definition. The second question is "If you're Microsoft, how to change orbit without causing too much pressure to the developer?" So far, the answer is: new releases each year, until the developers meet up. ASP.NET MVC's first product was released last March. Released in March this year, ASP.NET MVC 2.0. 3.0 RC 2 is currently in phase, expected to be released next March. December 10, Microsoft released ASP.NET MVC 3.0 Release Candidate 2. RC 2 is built on top of Microsoft's commitment to the jQuery: The default project template into jQuery 1.4.4, jQuery Validation 1.7 and jQuery UI. Although people think that Microsoft will focus shifted away from server-side controls to be a joke, but the introduction of Microsoft's jQuery UI is that this is the real thing. For those worried about the scalability of the developers, there are many excellent control can replace the session state. With SessionState property, you can tell the controller session state is read-only, read-write, or can be completely ignored in the. This site is no single server, but if a server needs to access another server session state, then this approach can provide a great help. MVC 3 contains Razor view engine. By default, the engine will be encoded HTML output, so that we can easily output on the screen the text of the original. HTML injection attacks even without the risk of encoded text can not easily prevent the page rendering. For many C # developers in the end do what is most shocking that MVC 3 for the controller and view and embrace the dynamic type. ViewBag property will open a dynamic object, developers can run on top of the object to add attributes. In general, it is used to send the view from the controller non-mode data. Scott Guthrie provides state of the sample contains text (such as the current time) and used to assemble the list box entries.

Error using Session in IIS

- by flashnik

After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly. Here is part of web.config: <system.web> <globalization culture="ru-RU" uiCulture="ru-RU" /> <compilation debug="true" defaultLanguage="c#"> <assemblies> <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> </assemblies> </compilation> <pages enableEventValidation="false" enableSessionState="true"> <controls> <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </controls> </pages> <httpHandlers> <remove verb="*" path="*.asmx" /> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" /> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="SearchUrlRewriter" type="Synonymizer.SearchUrlRewriter, Synonymizer, Version=1.0.0.0, Culture=neutral" /> <add name="Session" type="System.Web.SessionStateModule" /> </httpModules> <sessionState cookieless="UseCookies" cookieName="My_SessionId" mode="InProc" stateNetworkTimeout="5" /> <customErrors mode="Off" /> </system.web> What else do I need to do to make it work??

onCommand on button not firing inside gridView??

- by sah302

This is really driving me crazy. I've got a button inside a gridview to remove that item from the gridview (its datasource is a list). I've got the list being saved to session anytime a change is being made to it, and on page_load check if that session variable is empty, if not, then set that list to bind to the gridview. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'If Not Session("associatedFaculty") Is Nothing Then' ' Dim associatedFacultyArray As User() = DirectCast(Session("associatedFaculty"), User())' ' associatedFaculty = associatedFacultyArray.ToList()' 'End If' Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) Session("associatedFaculty") = associatedFaculty.ToArray() gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) Session.Add("associatedFaculty", associatedFaculty.ToArray()) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub Delete(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) End Sub End Class Markup: <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList>  <asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" OnClientClick="incrementCounter();" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now here is the crazy part I am simply boggled by, if I uncomment the If Not Session... block of page_load, then deleteUser will never fire when btnUnassignUser is clicked. If I keep it commented out...it fires no problem, but then of course my list can never have more than one item since I am not loading the saved list from session into the gridview but just a fresh one. But the button click is being registered, because page_load is being stepped through again when I am viewing in debug mode, just deleteUser never fires. Why is this happening?? And how can I fix it??

Algorithm for dragging objects on a fixed grid

- by FlyingStreudel

Hello, I am working on a program for the mapping and playing of the popular tabletop game D&D :D Right now I am working on getting the basic functionality like dragging UI elements around, snapping to the grid and checking for collisions. Right now every object when released from the mouse immediately snaps to the nearest grid point. This causes an issue when something like a player object snaps to a grid point that has a wall -or other- adjacent. So essentially when the player is dropped they wind up with some of the wall covering them. This is fine and working as intended, however the problem is that now my collision detection is tripped whenever you try to move this player because its sitting underneath a wall and because of this you cant drag the player anymore. Here is the relevant code: void UIObj_MouseMove(object sender, MouseEventArgs e) { blocked = false; if (dragging) { foreach (UIElement o in ((Floor)Parent).Children) { if (o.GetType() != GetType() && o.GetType().BaseType == typeof(UIObj) && Math.Sqrt(Math.Pow(((UIObj)o).cX - cX, 2) + Math.Pow(((UIObj)o).cY - cY, 2)) < Math.Max(r.Height + ((UIObj)o).r.Height, r.Width + ((UIObj)o).r.Width)) { double Y = e.GetPosition((Floor)Parent).Y; double X = e.GetPosition((Floor)Parent).X; Geometry newRect = new RectangleGeometry(new Rect(Margin.Left + (X - prevX), Margin.Top + (Y - prevY), Margin.Right + (X - prevX), Margin.Bottom + (Y - prevY))); GeometryHitTestParameters ghtp = new GeometryHitTestParameters(newRect); VisualTreeHelper.HitTest(o, null, new HitTestResultCallback(MyHitTestResultCallback), ghtp); } } if (!blocked) { Margin = new Thickness(Margin.Left + (e.GetPosition((Floor)Parent).X - prevX), Margin.Top + (e.GetPosition((Floor)Parent).Y - prevY), Margin.Right + (e.GetPosition((Floor)Parent).X - prevX), Margin.Bottom + (e.GetPosition((Floor)Parent).Y - prevY)); InvalidateVisual(); } prevX = e.GetPosition((Floor)Parent).X; prevY = e.GetPosition((Floor)Parent).Y; cX = Margin.Left + r.Width / 2; cY = Margin.Top + r.Height / 2; } } internal virtual void SnapToGrid() { double xPos = Margin.Left; double yPos = Margin.Top; double xMarg = xPos % ((Floor)Parent).cellDim; double yMarg = yPos % ((Floor)Parent).cellDim; if (xMarg < ((Floor)Parent).cellDim / 2) { if (yMarg < ((Floor)Parent).cellDim / 2) { Margin = new Thickness(xPos - xMarg, yPos - yMarg, xPos - xMarg + r.Width, yPos - yMarg + r.Height); } else { Margin = new Thickness(xPos - xMarg, yPos - yMarg + ((Floor)Parent).cellDim, xPos - xMarg + r.Width, yPos - yMarg + ((Floor)Parent).cellDim + r.Height); } } else { if (yMarg < ((Floor)Parent).cellDim / 2) { Margin = new Thickness(xPos - xMarg + ((Floor)Parent).cellDim, yPos - yMarg, xPos - xMarg + ((Floor)Parent).cellDim + r.Width, yPos - yMarg + r.Height); } else { Margin = new Thickness(xPos - xMarg + ((Floor)Parent).cellDim, yPos - yMarg + ((Floor)Parent).cellDim, xPos - xMarg + ((Floor)Parent).cellDim + r.Width, yPos - yMarg + ((Floor)Parent).cellDim + r.Height); } } } Essentially I am looking for a simple way to modify the existing code to allow the movement of a UI element that has another one sitting on top of it. Thanks!

How best to modernize the 2002-era J2EE app?

- by user331465

I have this friend.... I have this friend who works on a java ee application (j2ee) application started in the early 2000's. Currently they add a feature here and there, but have a large codebase. Over the years the team has shrunk by 70%. [Yes, the "i have this friend is". It's me, attempting to humorously inject teenage high-school counselor shame into the mix] Java, Vintage 2002 The application uses EJB 2.1, struts 1.x, DAO's etc with straight jdbc calls (mixture of stored procedures and prepared statements). No ORM. For caching they use a mixture of OpenSymphony OSCache and a home-grown cache layer. Over the last few years, they have spent effort to modernize the UI using ajax techniques and libraries. This largely involves javascript libaries (jquery, yui, etc). Client Side On the client side, the lack of upgrade path from struts1 to struts2 discouraged them from migrating to struts2. Other web frameworks became popular (wicket, spring , jsf). Struts2 was not the "clear winner". Migrating all the existing UI from Struts1 to Struts2/wicket/etc did not seem to present much marginal benefit at a very high cost. They did not want to have a patchwork of technologies-du-jour (subsystem X in Struts2, subsystem Y in Wicket, etc.) so developer write new features using Struts 1. Server Side On the server side, they looked into moving to ejb 3, but never had a big impetus. The developers are all comfortable with ejb-jar.xml, EJBHome, EJBRemote, that "ejb 2.1 as is" represented the path of least resistance. One big complaint about the ejb environment: programmers still pretend "ejb server runs in separate jvm than servlet engine". No app server (jboss/weblogic) has ever enforced this separation. The team has never deployed the ejb server on a separate box then the app server. The ear file contains multiple copies of the same jar file; one for the 'web layer' (foo.war/WEB-INF/lib) and one for the server side (foo.ear/). The app server only loads one jar. The duplications makes for ambiguity. Caching As for caching, they use several cache implementations: OpenSymphony cache and a homegrown cache. Jgroups provides clustering support Now What? The question: The team currently has spare cycles to to invest in modernizing the application? Where would the smart investor spend them? The main criteria: 1) productivity gains. Specifically reducing the time to develope new subsystems features and reduced maintenance. 2) performance/scalability. They do not care about fashion or techno-du-jour street cred. What do you all recommend? On the persistence side Switch everything (or new development only) to JPA/JPA2? Straight hibernate? Wait for Java EE 6? On the client/web-framework side: Migrate (some or all) to struts2? wicket? jsf/jsf2? As for caching: terracotta? ehcache? coherence? stick with what they have? how best to take advantage of the huge heap sizes that the 64-bit jvms offer? Thanks in advance.

The registartion for the handler is done as below: private void InitializeComponent() { this.dtgBatches.SortCommand += new System.Web.UI.WebControls.DataGridSortCommandEventHandler(this.dtgBatches_SortCommand); }

How to refresh a GridView?

- by Daniel

Hello everyone, I have a GridView which is pretty similar to the Google tutorial, except that I want to add the ImageViews on runtime (via a subactivity). The results are okay, but the layout of the View is messed up: The GridView doesn't fill the content of its parent, what do I have to do to design it properly? Here the code of adding the children: public void initializeWorkbench(GridView gv, Vector<String> items) { Prototype.workbench.setDimension(screenWidth, divider.height()+workbenchArea.height()); Prototype.workbench.activateWorkbench(); // this measures the workbench correctly Log.d(Prototype.TAG, "workbench width: "+Prototype.workbench.getMeasuredWidth()); // 320 Log.d(Prototype.TAG, "workbench height: "+Prototype.workbench.getMeasuredHeight()); // 30 ImageAdapter imgAdapter = new ImageAdapter(this.getContext(), items); gv.setAdapter(imgAdapter); gv.measure(screenWidth, screenHeight); gv.requestLayout(); gv.forceLayout(); Log.d(Prototype.TAG, "gv width: "+gv.getMeasuredWidth()); // 22 Log.d(Prototype.TAG, "gv height: "+gv.getMeasuredHeight()); // 119 Prototype.workbench.setDimension(screenWidth, divider.height()+workbenchArea.height()); } } activateWorkbench, setDimension and measure in the workbench (LinearLayout above the GridView): public void activateWorkbench() { if(this.equals(Prototype.workbench)) { this.setOrientation(VERTICAL); show = true; measure(); } } public void setDimension(int w, int h) { width = w; height = h; this.setLayoutParams(new LinearLayout.LayoutParams(width, height)); this.invalidate(); } private void measure() { if (this.getOrientation() == LinearLayout.VERTICAL) { int h = 0; int w = 0; this.measureChildren(0, 0); for (int i = 0; i < this.getChildCount(); i++) { View v = this.getChildAt(i); h += v.getMeasuredHeight(); w = (w < v.getMeasuredWidth()) ? v.getMeasuredWidth() : w; } if (this.equals(Prototype.tagarea)) height = (h < height) ? height : h; if (this.equals(Prototype.tagarea)) width = (w < width) ? width : w; } this.setMeasuredDimension(width, height); } The ImageAdapter constructor: public ImageAdapter(Context c, Vector<String> items) { mContext = c; boolean mExternalStorageAvailable = false; boolean mExternalStorageWriteable = false; String state = Environment.getExternalStorageState(); if (Environment.MEDIA_MOUNTED.equals(state)) { // We can read and write the media mExternalStorageAvailable = mExternalStorageWriteable = true; } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) { // We can only read the media mExternalStorageAvailable = true; mExternalStorageWriteable = false; } else { // Something else is wrong. It may be one of many other states, but // all we need // to know is we can neither read nor write mExternalStorageAvailable = mExternalStorageWriteable = false; } if (mExternalStorageAvailable && mExternalStorageWriteable) { for (String item : items) { File f = new File(item); if (f.exists()) { try { FileInputStream fis = new FileInputStream(f); Bitmap b = BitmapFactory.decodeStream(fis); bitmaps.add(b); files.add(f); } catch (FileNotFoundException e) { Log.e(Prototype.TAG, "", e); } } } } } And the xml layout: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="bottom" android:paddingLeft="0px" android:paddingTop="0px" android:paddingRight="0px"> <com.unimelb.pt3.ui.TransparentPanel android:id="@+id/workbench" android:layout_width="fill_parent" android:layout_height="10px" android:paddingTop="0px" android:paddingLeft="0px" android:paddingBottom="0px" android:paddingRight="0px"> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:columnWidth="90dp" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:stretchMode="columnWidth" android:gravity="center" /> </com.unimelb.pt3.ui.TransparentPanel> </LinearLayout>

Trying to convert string to datetime

- by user1596472

I am trying to restrict a user from entering a new record if the date requested already exits. I was trying to do a count to see if the table that the record would be placed in already has that date 1 or not 0. I have a calendar extender attached to a text box which has the date. I keep getting either a: String was not recognized as a valid DateTime. or Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'. depending on the different things I have tried. Here is my code. TextBox startd = (TextBox)(DetailsView1.FindControl("TextBox5")); TextBox endd = (TextBox)(DetailsView1.FindControl("TextBox7")); DropDownList lvtype = (DropDownList)(DetailsView1.FindControl("DropDownList6")); DateTime scheduledDate = DateTime.ParseExact(startd.Text, "dd/MM/yyyy", null); DateTime endDate = DateTime.ParseExact(endd.Text, "dd/MM/yyyy", null); DateTime newstartDate = Convert.ToDateTime(startd.Text); DateTime newendDate = Convert.ToDateTime(endd.Text); //foreach (DataRow row in sd.Tables[0].Rows) DateTime dt = newstartDate; while (dt <= newendDate) { //for retreiving from table Decimal sd = SelectCountDate(dt, lvtype.SelectedValue, countDate); String ndt = Convert.ToDateTime(dt).ToShortDateString(); // //start = string.CompareOrdinal(scheduledDate, ndt); // // end = string.CompareOrdinal(endDate, ndt); //trying to make say when leavetpe is greater than count 1 then throw error. if (sd > 0) { Response.Write("<script>alert('Date Already Requested');</script>"); } dt.AddDays(1); } ^^^ This version throws the: "String was not recognized as valid date type" error But if i replace the string with either of these : /*-----------------------Original------------------------------------ string scheduledDate = Convert.ToDateTime(endd).ToShortDateString(); string endDate = Convert.ToDateTime(endd).ToShortDateString(); -------------------------------------------------------------------*/ /*----------10-30--------------------------------------- DateTime scheduledDate = DateTime.Parse(startd.Text); DateTime endDate = DateTime.Parse(endd.Text); ------------------------------------------------------*/ I get the "Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'." error. I am just trying to stop a user from entering a record date that already exits. <InsertItemTemplate> <asp:TextBox ID="TextBox5" runat="server" Height="19px" Text='<%# Bind("lstdate", "{0:MM/dd/yyyy}") %>' Width="67px"></asp:TextBox> <asp:CalendarExtender ID="TextBox5_CalendarExtender" runat="server" Enabled="True" TargetControlID="TextBox5"> </asp:CalendarExtender> <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox5" ErrorMessage="*Leave Date Required" ForeColor="Red"></asp:RequiredFieldValidator> <br /> <asp:CompareValidator ID="CompareValidator18" runat="server" ControlToCompare="TextBox7" ControlToValidate="TextBox5" ErrorMessage="Leave date cannot be after start date" ForeColor="Red" Operator="LessThanEqual" ToolTip="Must choose start date before end date"></asp:CompareValidator> </InsertItemTemplate>

How to filter using a dropdown in Knockout

- by user517406

I have just started using Knockout and I want to filter my data that I am displaying in my UI by selecting an item from a dropdown. I have got so far, but I cannot get the selected value from my dropdown yet, and then after that I need to actually filter the data displayed based upon that value. Here is my code so far : @model Models.Fixture @{ ViewBag.Title = "Fixtures"; Layout = "~/Areas/Development/Views/Shared/_Layout.cshtml"; } @Scripts.Render("~/bundles/jqueryval") <script type="text/javascript" src="@Url.Content("~/Scripts/knockout-2.1.0.js")"></script> <script type="text/javascript"> function FixturesViewModel() { var self = this; var baseUri = '@ViewBag.ApiUrl'; self.fixtures = ko.observableArray(); self.teams = ko.observableArray(); self.update = function (fixture) { $.ajax({ type: "PUT", url: baseUri + '/' + fixture.Id, data: fixture }); }; self.sortByAwayTeamScore = function () { this.fixtures.sort(function(a, b) { return a.AwayTeamScore < b.AwayTeamScore ? -1 : 1; }); }; self.select = function (team) { }; $.getJSON("/api/fixture", self.fixtures); $.getJSON("/api/team", self.teams); } $(document).ready(function () { ko.applyBindings(new FixturesViewModel()); }); </script> <div class="content"> <div> <table><tr><td><select data-bind="options: teams, optionsText: 'TeamName', optionsCaption: 'Select...', optionsValue: 'TeamId', click: $root.select"> </select></td></tr></table> <table class="details ui-widget-content"> <thead> <tr><td>FixtureId</td><td>Season</td><td>Week</td><td>AwayTeam</td><td><a id="header" data-bind='click: sortByAwayTeamScore'>AwayTeamScore</a></td><td>HomeTeam</td><td>HomeTeamScore</td></tr> </thead> <tbody data-bind="foreach: fixtures"> <tr> <td><span data-bind="text: $data.Id"></span></td> <td><span data-bind="text: $data.Season"></span></td> <td><span data-bind="text: $data.Week"></span></td> <td><span data-bind="text: $data.AwayTeamName"></span></td> <td><input type="text" data-bind="value: $data.AwayTeamScore"/></td> <td><span data-bind="text: $data.HomeTeamName"></span></td> <td><input type="text" data-bind="value: $data.HomeTeamScore"/></td> <td><input type="button" value="Update" data-bind="click: $root.update"/></td> </tr> </tbody> </table> </div> </div> Can anybody please advise on this?

Weird GWT issue causing IE threads to skyrocket.

- by WesleyJohnson

I'm not sure if this is an issue with GWT, JavaScript, Java, IE or just poor programming, but I'll try to explain. We're implementing web based chat program at work and some of our users have unreliable connections. So we're running into issues where they send out a new message and after x number of milliseconds have passed, the XHR request timesout and the client tries to resend the message again. The issue we ran into was sometimes the message would make it to the server and into the DB, but the XHR request wouldn't make it back to the client so the client was essentially retrying requests that had alread made it to the server. To mitigate this issue, we now send along a count/key with the message. The client says, hey I'm sending msg 50 and it's text is this. If the server already has that message, it just sends back "ok, I got it" and doens't insert into the DB again, eliminating dupes. So the client is free to keep retrying over and over until finally a call comes back from the server saying "Ok, I got it" and then it increments the key and moves on (or we keep them out of the chat if it fails enough). Anyway, so that's the background of what we're doing. The issue is, when we add this code on some versions of IE the threads start increasing gradually everytime it's accessed. On IE8 for Windows7 x64 it doesn't really seem to do it, but on IE8 for Windows Vista x86 it does. So I can't really pinpoint if it's a fluke or my code. Maybe someone had some ideas on a better way to do this. Here is some pseudo code: (the issue seems appear where I increment messageCount? Is this a scope thing, naming conflict, maybe the issue is entirely somewhere else and I'm way off base. public class SFChatClient implements EntryPoint { private List<String> messageQueue; private Integer messageCount = 0; public void onModuleLoad() { messageQueue = new ArrayList<String>(); // setup ui and what not // add a keyhandler to an input box that checks for <ENTER> and calls sendMEssage() } private void sendMessage() { // add message content to the UI for the chat messageQueue.add( //get message from user ); sendQueuedMessages(); } private void sendQueuedMessages() { if( messageQueue.size() > 0 ) { String outgoingMessage = messageQueue.get( 0 ); WebServiceClass.sendMessage( outgoingMessage, messageCount, new WebServiceHandler() { public void onSuccess() { // Delete item 0 from messageQueue messageCount = messageCount + 1; // <--- this seems to cause IE to leak threads. Taking out this code stops the issue??? sendQueuedMessages(); } public void onError() { // Do error handling sendQueuedMessages(); } } ); } } } public class WebServiceClass() { public void sendMessage( String message, Integer messageCount, handler ) { RequestBuilder builder = new RequestBuilder(// create request builder with proper params for the web service url, JSON content type, etc ) { public void onSuccess() { handler.onSuccess() } public void onError() { handler.onError() } } builder.setData( // JSON with message ); bulder.send(); } }

jQuery autocomplete. Doesn't reveal existing matches.

- by Alexander

Hello fellow engineers. I have come across a problem I just can't solve. I am using autocomplete plugin for jQuery on an input. The HTML looks something like this: <tr id="row_house" class="no-display"> <td class="col_num">4</td> <td class="col_label">House Number</td> <td class="col_data"> <input type="text" title="House Number" name="house" id="house"/> <button class="pretty_button ui-state-default ui-corner-all button-finish">Get house info</button> </td> </tr> I am sure that this is the only id="house" field. Other fields that are before this one work fine with autocomplete, and it's basically the same algorithm (other variables, other data, other calls). So why doesn't it work like it should work with the following init. code: $("#house").autocomplete(["1/4","6","6/1","6/4","8","8/1","8/5","10","10/1","10/3","10/4","12","12/1","12/5","12/6","14","14/1","15","15/1","15/2","15/4","15/5","16","16/1","16/2","16/21","16/2B","16/3","16/4","17","17/1","17/2","17/4","17/5","17/6","17/7","17/8","18","18/1","18/2","18/3","18/5","18/95","19","19/1","19/2","19/3","19/4","19/5","19/6","19/7","19/8","20","20/1","20/2","20/3","20/4","21","21/1","21/2","21/3","21/4","22","22/9","23","23/2","23/4","24","24/1","24/2","24/3","24/A","25","25/1","25/10","25/2","25/4","25/5","25/6","25/7","25/8","25/9","26","26/1","26/6","27","27/2","28","28/1","29","29/2","29/3","29/4","30","30/1","30/2","30/3","31","31/1","31/3","32/A","33","34","34/1","34/11","34/2","34/3","35","35/1","35/2","35/4","36","36/1","36/A","37","37/1","37/2","38","38/1","38/2","39/1","39/2","39/3","39/4","40","40/1","41","41/2","42","43","44","45","45/1","45/10","45/11","45/12","45/13","45/14","45/15","45/16","45/17","45/2","45/3","45/6","45/7","45/8","45/9","46","47","47/2","49","49/1","50","51","51/1","51/2","52","53","54","55/7","66","109","122","190/8","412"], {minChars:1, mustMatch:true}).result(function(event, result, formatted) { var found=false; for(var index=0; index<HChouses.length; index++) //HChouses is the same array used for init, but each entry is paired with a database ID. if(HChouses[index][0]==result) { found=true; HChouseId=HChouses[index][1]; $("#row_house .button-finish").click(function() { QueryServer("HouseConnect","FillData",true,HChouseId); //this performs an AJAX request }); break; } if(!found) $("#row_house .button-finish").unbind("click"); }); Each time I start typing (say I press the "1" button), the text appears and gets deleted instantly. Rarely at all after repeated presses I get the list (although much shorter than it should be) But if after that I press the second digit, the whole thing disappears again. P.S. I use Firefox 3.6.3 for development.

ASP.NET JavaScript Routing for ASP.NET MVC–Constraints

- by zowens

If you haven’t had a look at my previous post about ASP.NET routing, go ahead and check it out before you read this post: http://weblogs.asp.net/zowens/archive/2010/12/20/asp-net-mvc-javascript-routing.aspx And the code is here: https://github.com/zowens/ASP.NET-MVC-JavaScript-Routing Anyways, this post is about routing constraints. A routing constraint is essentially a way for the routing engine to filter out route patterns based on the day from the URL. For example, if I have a route where all the parameters are required, I could use a constraint on the required parameters to say that the parameter is non-empty. Here’s what the constraint would look like: Notice that this is a class that inherits from IRouteConstraint, which is an interface provided by System.Web.Routing. The match method returns true if the value is a match (and can be further processed by the routing rules) or false if it does not match (and the route will be matched further along the route collection). Because routing constraints are so essential to the route matching process, it was important that they be part of my JavaScript routing engine. But the problem is that we need to somehow represent the constraint in JavaScript. I made a design decision early on that you MUST put this constraint into JavaScript to match a route. I didn’t want to have server interaction for the URL generation, like I’ve seen in so many applications. While this is easy to maintain, it causes maintenance issues in my opinion. So the way constraints work in JavaScript is that the constraint as an object type definition is set on the route manager. When a route is created, a new instance of the constraint is created with the specific parameter. In its current form the constraint function MUST return a function that takes the route data and will return true or false. You will see the NotEmpty constraint in a bit. Another piece to the puzzle is that you can have the JavaScript exist as a string in your application that is pulled in when the routing JavaScript code is generated. There is a simple interface, IJavaScriptAddition, that I have added that will be used to output custom JavaScript. Let’s put it all together. Here is the NotEmpty constraint. There’s a few things at work here. The constraint is called “notEmpty” in JavaScript. When you add the constraint to a parameter in your C# code, the route manager generator will look for the JsConstraint attribute to look for the name of the constraint type name and fallback to the class name. For example, if I didn’t apply the “JsConstraint” attribute, the constraint would be called “NotEmpty”. The JavaScript code essentially adds a function to the “constraintTypeDefs” object on the “notEmpty” property (this is how constraints are added to routes). The function returns another function that will be invoked with routing data. Here’s how you would use the NotEmpty constraint in C# and it will work with the JavaScript routing generator. The only catch to using route constraints currently is that the following is not supported: The constraint will work in C# but is not supported by my JavaScript routing engine. (I take pull requests so if you’d like this… go ahead and implement it). I just wanted to take this post to explain a little bit about the background on constraints. I am looking at expanding the current functionality, but for now this is a good start. Thanks for all the support with the JavaScript router. Keep the feedback coming!

Data Quality and Master Data Management Resources

- by Dejan Sarka

Many companies or organizations do regular data cleansing. When you cleanse the data, the data quality goes up to some higher level. The data quality level is determined by the amount of work invested in the cleansing. As time passes, the data quality deteriorates, and you need to repeat the cleansing process. If you spend an equal amount of effort as you did with the previous cleansing, you can expect the same level of data quality as you had after the previous cleansing. And then the data quality deteriorates over time again, and the cleansing process starts over and over again. The idea of Data Quality Services is to mitigate the cleansing process. While the amount of time you need to spend on cleansing decreases, you will achieve higher and higher levels of data quality. While cleansing, you learn what types of errors to expect, discover error patterns, find domains of correct values, etc. You don’t throw away this knowledge. You store it and use it to find and correct the same issues automatically during your next cleansing process. The following figure shows this graphically. The idea of master data management, which you can perform with Master Data Services (MDS), is to prevent data quality from deteriorating. Once you reach a particular quality level, the MDS application—together with the defined policies, people, and master data management processes—allow you to maintain this level permanently. This idea is shown in the following picture. OK, now you know what DQS and MDS are about. You can imagine the importance on maintaining the data quality. Here are some resources that help you preparing and executing the data quality (DQ) and master data management (MDM) activities. Books Dejan Sarka and Davide Mauri: Data Quality and Master Data Management with Microsoft SQL Server 2008 R2 – a general introduction to MDM, MDS, and data profiling. Matching explained in depth. Dejan Sarka, Matija Lah and Grega Jerkic: MCTS Self-Paced Training Kit (Exam 70-463): Building Data Warehouses with Microsoft SQL Server 2012 – I wrote quite a few chapters about DQ and MDM, and introduced also SQL Server 2012 DQS. Thomas Redman: Data Quality: The Field Guide – you should start with this book. Thomas Redman is the father of DQ and MDM. Tyler Graham: Microsoft SQL Server 2012 Master Data Services – MDS in depth from a product team mate. Arkady Maydanchik: Data Quality Assessment – data profiling in depth. Tamraparni Dasu, Theodore Johnson: Exploratory Data Mining and Data Cleaning – advanced data profiling with data mining. Forthcoming presentations I am presenting a DQS and MDM seminar at PASS SQL Rally Amsterdam 2013: Wednesday, November 6th, 2013: Enterprise Information Management with SQL Server 2012 – a good kick start to your first DQ and / or MDM project. Courses Data Quality and Master Data Management with SQL Server 2012 – I wrote a 2-day course for SolidQ. If you are interested in this course, which I could also deliver in a shorter seminar way, you can contact your closes SolidQ subsidiary, or, of course, me directly on addresses [email protected] or [email protected]. This course could also complement the existing courseware portfolio of training providers, which are welcome to contact me as well. Start improving the quality of your data now!

Tool to convert blogger.com content to dasBlog

- by Daniel Moth

Due to blogger.com dropping FTP support, I've had to move my blog. If you are in a similar situation, this post will help you by showing you the necessary steps to take. Goals No loss on blog posts, comments AND all existing permalinks continue to work (redirect to the correct place). Steps Download the XML files corresponding to your blogger.com content and store them in a folder. Install and configure dasBlog on your local machine. Configure your web.config file (will need updating once you run step 4). Use the tool I describe further down to generate the content and place it at the right place. Test your site locally. Once you are happy, repeat step 2 on your hosting provider of choice. Remember to copy up your dasBlog theme folder if you created one. Copy up the local web.config file and the XML dasBlog content files generated by the tool of step 4. Test your site on the server. Once you are happy, go live (following instructions from your hoster). In my case, I gave the nameservers from my new hoster to my existing domain registrar and they made the switch. Tool (code) At step 4 above I referred to a tool. That is an overstatement, it is simply one 450-line C#code file that you can download here: BloggerToDasBlog.cs. I used this from a .NET 2.0 console app (and I run it under the Visual Studio debugger, i.e. F5) like this: Program.cs. The console app referenced the dasBlog 2.3 ASP.NET Blogging Engine i.e. the newtelligence.DasBlog.Runtime.dll assembly. Let me describe what the code does: Input: A path to a folder where the XML files from the old blogger.com blog reside. It can deal with both types of XML file. A full file path to a file where it creates XML redirect input (as required by the rewriteMap mentioned here). The blog URL. The author's email. The blog author name. A path to an empty folder where the new XML dasBlog content files will get created. The subfolder name used after the domain name in the URL. The 3 reg ex patterns to use. You can use the same as mine, but will need to tweak the monthly_archive rule. Again, to see what values I passed for all the above, see my Program.cs file. Output: It creates dasBlog XML files in the folder specified. It creates those by parsing the old blogger.com XML files that reside in the folder specified. After that is generated, copy it to the "Content" folder under your dasBlog installation. It creates an XML file with a single ignorable root element and a bunch of inner XML elements. You can copy paste these in the web.config file as discussed in this post. Other notes: For each blog post, it detects outgoing links to itself (i.e. to the same blog), and rewrites those to point to the new URLs. So internal links do not rely on the web.config redirects. It deals with duplicate post titles; it does not deal with triplicates and higher. Removes all references to blogger.com (e.g. references to [email protected], the injected hidden footer for statistics that each blog post has and others – see the code). It creates a lot of diagnostic output (in the Output window) and indeed the documentation for the code is in the Debug.WriteLine statements ;) This is not code I will maintain or support – it was a throwaway one-use project that I am sharing here as a starting point for anyone finding themselves in the same boat that I was. Enjoy "as is". Comments about this post welcome at the original blog.

Home Energy Management & Automation with Windows Phone 7

A number of people at Clarity are personally interested in home energy conservation and home automation. We feel that a mobile device is a great fit for bringing this idea to fruition. While this project is merely a concept and not directly associated with Microsofts Hohm web service, it provides a great model for communicating the concept. I wanted to take the idea a step further and combine saving energy in your home with the ability to track water usage and control your home devices. I designed an application that focuses on total home control and not just energy usage. Application Overview By monitoring home consumption in real time and with yearly projections users can pinpoint vampire devices, times of high or low consumption, and wasteful patterns of energy use. Energy usage meters indicate total current consumption as well as individual device consumption. Users can then use the information to take action, make adjustments, and change their consumption behaviors. The app can be used to automate certain systems like lighting, temperature, or alarms. Other features can be turned on an off at the touch of a toggle switch on your phone, away from home. Forget to turn off the TV or shut the garage door? No problem, you can do it from your phone. Through settings you can enable and disable features of the phone that apply to your home making it a completely customized and convenient experience. To be clear, this equates to more security, big environmental impact, and even bigger savings. Design and User Interface Since this panorama application is designed for win phone 7 devices, it complies with the UI Design and Interaction Guide for wp7. I developed the frame and page hierarchy from existing examples. The interface takes advantage of the interactive nature of touch screens with slider controls, pivot control views, and toggle switches to turn on and off devices (not shown in mockup). I followed recommendations for text based elements and adapted the tile notifications to display the most recent user activity. For example, the mockup indicates upon launching the app that the last thing you did was program the thermostat. This model is great for quick launching common user actions. One last design feature to point out is the technical reasons for supplying both light and dark themes for the app. Since this application is targeting energy consumption it only makes sense to consider the effect of the apps background color or image on the phones energy use. When displaying darker colors like black the OLED display may use less power, extending battery life. Other Considerations For now I left out options of wind and solar powered energy options because they are not available to everyone. Renewable energy sources and new technologies associated with them are definitely ideas to keep in mind for a next iteration. Another idea to explore for such an application would be to include a savings model similar to mint.com. In addition to general energy-saving recommendations the application could recommend customized ways to save based on your current utility providers and available options in your area. If your television or refrigerator is guilty of sucking a lot of energy then you may see recommendations for energy star products that could save you even more money!

Guest (and occasional co-host) on Jesse Liberty's Yet Another Podcast

- by Jon Galloway

I was a recent guest on Jesse Liberty's Yet Another Podcast talking about the latest Visual Studio, ASP.NET and Azure releases. Download / Listen: Yet Another Podcast #75–Jon Galloway on ASP.NET/ MVC/ Azure Co-hosted shows: Jesse's been inviting me to co-host shows and I told him I'd show up when I was available. It's a nice change to be a drive-by co-host on a show (compared with the work that goes into organizing / editing / typing show notes for Herding Code shows). My main focus is on Herding Code, but it's nice to pop in and talk to Jesse's excellent guests when it works out. Some shows I've co-hosted over the past year: Yet Another Podcast #76–Glenn Block on Node.js & Technology in China Yet Another Podcast #73 - Adam Kinney on developing for Windows 8 with HTML5 Yet Another Podcast #64 - John Papa & Javascript Yet Another Podcast #60 - Steve Sanderson and John Papa on Knockout.js Yet Another Podcast #54–Damian Edwards on ASP.NET Yet Another Podcast #53–Scott Hanselman on Blogging Yet Another Podcast #52–Peter Torr on Windows Phone Multitasking Yet Another Podcast #51–Shawn Wildermuth: //build, Xaml Programming & Beyond And some more on the way that haven't been released yet. Some of these I'm pretty quiet, on others I get wacky and hassle the guests because, hey, not my podcast so not my problem. Show notes from the ASP.NET / MVC / Azure show: What was just released Visual Studio 2012 Web Developer features ASP.NET 4.5 Web Forms Strongly Typed data controls Data access via command methods Similar Binding syntax to ASP.NET MVC Some context: Damian Edwards and WebFormsMVP Two questions from Jesse: Q: Are you making this harder or more complicated for Web Forms developers? Short answer: Nothing's removed, it's just a new option History of SqlDataSource, ObjectDataSource Q: If I'm using some MVC patterns, why not just move to MVC? Short answer: This works really well in hybrid applications, doesn't require a rewrite Allows sharing models, validation, other code between Web Forms and MVC ASP.NET MVC Adaptive Rendering (oh, also, this is in Web Forms 4.5 as well) Display Modes Mobile project template using jQuery Mobile OAuth login to allow Twitter, Google, Facebook, etc. login Jon (and friends') MVC 4 book on the way: Professional ASP.NET MVC 4 Windows 8 development Jesse and Jon announce they're working on a new book: Pro Windows 8 Development with XAML and C# Jon and Jesse agree that it's nice to be able to write Windows 8 applications using the same skills they picked up for Silverlight, WPF, and Windows Phone development. Compare / contrast ASP.NET MVC and Windows 8 development Q: Does ASP.NET and HTML5 development overlap? Jon thinks they overlap in the MVC world because you're writing HTML views without controls Jon describes how his web development career moved from a preoccupation with server code to a focus on user interaction, which occurs in the browser Jon mentions his NDC Oslo presentation on Learning To Love HTML as Beautiful Code Q: How do you apply C# / XAML or HTML5 skills to Windows 8 development? Q: If I'm a XAML programmer, what's the learning curve on getting up to speed on ASP.NET MVC? Jon describes the difference in application lifecycle and state management Jon says it's nice that web development is really interactive compared to application development Q: Can you learn MVC by reading a book? Or is it a lot bigger than that? What is Azure, and why would I use it? Jon describes the traditional Azure platform mode and how Azure Web Sites fits in Q: Why wouldn't Jesse host his blog on Azure Web Sites? Domain names on Azure Web Sites File hosting options Q: Is Azure just another host? How is it different from any of the other shared hosting options? A: Azure gives you the ability to scale up or down whenever you want A: Other services are available if or when you want them

Travelling MVP #4: DevReach 2012

- by DigiMortal

Our next stop after Varna was Sofia where DevReach happens. DevReach is one of my favorite conferences in Europe because of sensible prices and strong speakers line-up. Also they have VIP-party after conference and this is good event to meet people you don’t see every day, have some discussion with speakers and find new friends. Our trip from Varna to Sofia took about 6.5 hours on bus. As I was tired from last evening it wasn’t problem for me as I slept half the trip. After smoking pause in Velike Tarnovo I watched movies from bus TV. We had supper later in city center Happy’s – place with good meat dishes and nice service. And next day it begun…. :) DevReach 2012 DevReach is held usually in Arena Mladost. It’s near airport and Telerik office. The event is organized by local MVP Martin Kulov together with Telerik. Two days of sessions with strong speakers is good reason enough for me to go to visit some event. Some topics covered by sessions: Windows 8 development web development SharePoint Windows Azure Windows Phone architecture Visual Studio Practically everybody can find some interesting session in every time slot. As the Arena is not huge it is very easy to go from one sessions to another if selected session for time slot is not what you expected. On the second floor of Arena there are many places where you can eat. There are simple chunk-food places like Burger King and also some restaurants. If you are hungry you will find something for your taste for sure. Also you can buy beer if it is too hot outside :) Weather was very good for October – practically Estonian summer – 25C and over. Sessions I visited Here is the list of sessions I visited at DevReach 2012: DevReach 2012 Opening & Welcome Messsage with Martin Kulov and Stephen Forte Principled N-Tier Solution Design with Steve Smith Data Patterns for the Cloud with Brian Randell .NET Garbage Collection Performance Tips with Sasha Goldshtein Building Secured, Scalable, Low-latency Web Applications with the Windows Azure Platform with Ido Flatow It’s a Knockout! MVVM Style Web Applications with Charles Nurse Web Application Architecture – Lessons Learned from Adobe Brackets with Brian Rinaldi Demystifying Visual Studio 2012 Performance Tools with Martin Kulov SPvNext – A Look At All the Exciting And New Features In SharePoint with Sahil Malik Portable Libraries – Why You Should Care with Lino Tadros I missed some sessions because of some death march projects that are going and that I have to coordinate but it was not big loss as I had time to walk around in session venue neighborhood and see Sofia Business Park. Next year again! I will be there again next year and hopefully more guys from Estonia will join me. I think it’s good idea to take short vacation for DevReach time and do things like we did this time – Bucharest, Varna, Sofia. It’s only good idea to plan some more free time so we are not very much in hurry and also we have no work stuff to do on the trip. This far this trip has been one of best trips I have organized and I will go and meet all those guys in this region again! :)
