  • Content controls have to be top-level controls

    - by horatio
    I have a website that can be accessed from www.blahblah.com and special.blahblah.com. The www site always works but occasionly I get a 'Content controls have to be top-level controls in a content page or a nested master page that references a master page' error on the special site. It's exactly the same code running in both situations and the offending page doesn't even have a master page. Why would it work all the time on one and fail sometimes on the other?

  • How to use Common Table Expression and check no duplication in SQL Server

    - by vodkhang
    I have a table references to itself. User table: id, username, managerid and managerid links back to id Now, I want to get all the managers including direct manager, manager of direct manager, so on and so forth... The problem is that I do not want to have a unstop recursive sql. So, I want to check if an id alreay in a list, I will not include it anymore. Here is my sql for that: with all_managers (id, username, managerid, idlist) as ( select u1.id, u1.username, u1.managerid, ' ' from users u1, users u2 where u1.id = u2.managerid and u2.id = 6 UNION ALL select u.id, u.username, u.managerid, idlist + ' ' + u.id from all_managers a, users u where a.managerid = u.id and charindex(cast(u.id as nvarchar(5)), idlist) != 0 ) select id, username from all_managers; The problem is that in this line: select u1.id, u1.username, u1.managerid, ' ' The SQL Server complains with me that I can not put ' ' as the initialized for idlist. nvarchar(40) does not work as well. I do not know how to declare it inside a common table expression like this one. Usually, in db2, I can just put varchar(40) My sample data: ID UserName ManagerID 1 admin 1 2 a 1 3 b 1 4 c 2 What I want to do is that I want to find all managers of c guy. The result should be: admin, a, b. Some of the user can be his manager (like admin) because the ManagerID does not allow NULL and some does not have direct manager. With common table expression, it can lead to an infinite recursive. So, I am also trying to avoid that situation by trying to not include the id twice. For example, in the 1st iteration, we already have id : 1, so, in the 2nd iteration and later on, 1 should never be allowed. I also want to ask if my current approach is good or not and any other solutions? Because if I have a big database with a deep hierarchy, I will have to initialize a big varchar to keep it and it consumes memory, right?

  • What would be the safest way to store objects of classes derived from a common interface in a common

    - by Svenstaro
    I'd like to manage a bunch of objects of classes derived from a shared interface class in a common container. To illustrate the problem, let's say I'm building a game which will contain different actors. Let's call the interface IActor and derive Enemy and Civilian from it. Now, the idea is to have my game main loop be able to do this: // somewhere during init std::vector<IActor> ActorList; Enemy EvilGuy; Civilian CoolGuy; ActorList.push_back(EvilGuy); ActorList.push_back(CoolGuy); and // main loop while(!done) { BOOST_FOREACH(IActor CurrentActor, ActorList) { CurrentActor.Update(); CurrentActor.Draw(); } } ... or something along those lines. This example obviously won't work but that is pretty much the reason I'm asking here. I'd like to know: What would be the best, safest, highest-level way to manage those objects in a common heterogeneous container? I know about a variety of approaches (Boost::Any, void*, handler class with boost::shared_ptr, Boost.Pointer Container, dynamic_cast) but I can't decide which would be the way to go here. Also I'd like to emphasize that I want to stay away as far as possible from manual memory management or nested pointers. Help much appreciated :).

  • Naming of ASP.NET controls inside User Controls with ASP.NET MVC

    - by skb
    I am wondering if there is a way to make ASP.NET controls play nicely with my ASP.NET MVC app. Here is what I am doing. I have an order page which displays info about a single Order object. The page will normally have a bunch of rows of data, each row representing an OrderItem object. Each row is an ASP.NET User Control. On the user control there is a form element with two text boxes (Quantity and Price), and an update button. When I click the update button, I expect the form to post the data for that individual OrderItem row to a controller method and update the OrderItem record in the database. Here is my problem: When the post happens, the framework complains because the fields on the form don't match the parameters on the controller method. Each form field is something like "OrderItem_1$Quantity" or "OrderItem_2$Price" instead of just "Quantity" or "Price" which would match my method parameters. I have been told that I can overcome this by making sure that the IDs of all my controls are unique for the page, but allow the NAMEs to be repeated between different forms, so that if a form for an individual row is posted, the name can be something that will match what is on my controller method. The only problem is that I am using ASP.NET controls for my text boxes (which I REALLY want to continue doing) and I can't find any way to override the name field. There is no Name propery on an ASP.NET control, and even when I try to set it using the Attributes accessor property by saying "control.Attributes["Name"] = "Price";" it just adds another name= attribute to the HTML tag which doesn't work. Does any one know how I can make this work? I really don't like all of the HtmlHelper functions like TextBox and DropDown because I hate having my .aspx be so PHP or ASP like with the <%% tags and everything. Thanks!

  • Accessing global variables of custom controls in ASP.NET

    - by CL4NCY
    Hi, I have built lots of custom asp.net controls which work really well separately but I want to somehow allow global access to all their variables from anywhere on the page. I have a central control called the ContentManager which I can use to store these variables. The problem I have is that all the controls are bound at different times so I only want the variables available after they're bound. For example I have many custom repeaters on the page which when bound I want to add a reference in the content manager so all their variables are then available to use. <Custom:ContentManager ID="cm" runat="server"/> <Custom:Repeater ID="r1" runat="server"/> <Custom:Repeater ID="r2" runat="server"/> <Custom:Repeater ID="r3" runat="server"/> Then I want a tag which can access all variables from any of these controls. <%= cm.controls["r1"].Items[0]["name"] %> The problem with this is that the variable isn't available until the repeater is bound so I might need to use events to push out the value to tags on the page like so: <Custom:Var ID="v1" control="r1" value="Items[0]["name"]" runat="server"/> Is this possible or can you recommend a better approach?

  • Having Fun with Coding4Fun&rsquo;s Windows Phone 7 Controls

    - by mbcrump
    I’m a big believer in having a hobby project as you can probably tell from the first sentence in my “personal webpage using Silverlight” article. One of my current hobby projects is to re-do my current WP7 application in the marketplace. I knew up front that I needed a “Loading” animation and a better “About” box. After starting to develop my own, I noticed a great set of WP7 controls by Coding4Fun and decided to use them in my new application. Before I go any further they are FREE and Open-Source. It is really simple to get started, just go to the CodePlex site and click the download button. After you have downloaded it then extract it to a Folder and you will have 4 DLL files. They are listed below: Now create a Windows Phone 7 Project and add references to the DLL’s by right clicking on the References folder and clicking “Add references”.   After adding the references, we can get started. I needed a ProgressOverlay animation or “Loading Screen” while my RSS feed is downloading. Basically, you just need to add the following namespace to whatever page you want the control on: xmlns:Controls="clr-namespace:Coding4Fun.Phone.Controls;assembly=Coding4Fun.Phone.Controls" And then the code inside your Grid or wherever you want the Loading screen placed. <Controls:ProgressOverlay Name="progressOverlay" > <Controls:ProgressOverlay.Content> <TextBlock>Loading</TextBlock> </Controls:ProgressOverlay.Content> </Controls:ProgressOverlay> Bam, you now have a great looking loading screen. Of course inside the ProgressOverlay, you may want to add a Visibility property to turn it off after your data loads if you are using MVVM or similar pattern.   Next up, I needed a nice clean “About Box” that looks good but is also functional. Meaning, if they click on my twitter name, web or email to launch the appropriate task. Again, this is only a few lines of code: var p = new AboutPrompt(); p.VersionNumber = "2.0"; p.Show("Michael Crump", "@mbcrump", "[email protected]", @"http://michaelcrump.net"); A nice clean “About” box with just a few lines of code! I’m all for code that I don’t have to write. It also comes with a pretty sweet InputPrompt for grabbing info from a user: The code for this is also very simple: InputPrompt input = new InputPrompt(); input.Completed += (s, e) => { MessageBox.Show(e.Result.ToString()); }; input.Title = "Input Box"; input.Message = "What does a \"Developer Large\" T-Shirt Mean? "; input.Show(); I also enjoyed the PhoneHelper that allows you to get data out of the WMAppManifest File very easy. So for example if I wanted the Version info from the WMAppManifest file. I could write one line and get it. PhoneHelper.GetAppAttribute("Version") Of course you would want to make sure you add the following using statement: using Coding4Fun.Phone.Controls.Data; You can’t have all these cool controls without a great set of Converters. The included BooleanToVisibility converter will convert a Boolean to and from a Visibility value. This is excellent when using something like a CheckBox to display a TextBox when its checked. See the example below: The code is below: <phone:PhoneApplicationPage.Resources> <Converters:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> </phone:PhoneApplicationPage.Resources> <CheckBox x:Name="checkBox"/> <TextBlock Text="Display Text" Visibility="{Binding ElementName=checkBox, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter} }"/> That’s not all the goodies included. They also provide a RoundedButton, TimePicker and several other converters. The documentation is great and I would recommend you give them a shot if you need any of this functionality. Btw, thank Brian Peek for his awesome work on Coding4Fun!  Subscribe to my feed

  • When would you use the Common Service Locator ?

    - by ajma
    I've been looking at the Common Service Locator as a way of abstracting my IoC container but I've been noticing that some people are strongly against this type of this. Do people recommend never using it? Always using it? or sometimes using it? If sometimes, then in what situations would you use it and what situations would you not use it.

  • Data Web Controls Enhancements in ASP.NET 4.0

    Traditionally, developers using Web controls enjoyed increased productivity but at the cost of control over the rendered markup. For instance, many ASP.NET controls automatically wrap their content in <table> for layout or styling purposes. This behavior runs counter to the web standards that have evolved over the past several years, which favor cleaner, terser HTML; sparing use of tables; and Cascading Style Sheets (CSS) for layout and styling. Furthermore, the <table> elements and other automatically-added content makes it harder to both style the Web controls using CSS and to work with the controls from client-side script. One of the aims of ASP.NET version 4.0 is to give Web Form developers greater control over the markup rendered by Web controls. Last week's article, Take Control Of Web Control ClientID Values in ASP.NET 4.0, highlighted how new properties in ASP.NET 4.0 give the developer more say over how a Web control's ID property is translated into a client-side id attribute. In addition to these ClientID-related properties, many Web controls in ASP.NET 4.0 include properties that allow the page developer to instruct the control to not emit extraneous markup, or to use an HTML element other than <table>. This article explores a number of enhancements made to the data Web controls in ASP.NET 4.0. As you'll see, most of these enhancements give the developer greater control over the rendered markup.

  • ASP.NET4.0-Compatibility Settings for rendering controls

    - by Jalpesh P. Vadgama
    With asp.net 4.0 Microsoft has taken a great step for rendering controls. Now it will have more cleaner html there are lots of enhancement for rendering html controls in asp.net 4.0 now all controls like Menu, List View and other controls renders more cleaner html. But recently i have faced strange problem in rendering controls I have my site in asp.net 3.5 and i want to convert it in asp.net 4.0. I have applied my style as per 3.5 rendering and some of items are obsolete in asp.net 4.0. Modifying style sheet was a tedious job here asp.net 4.0 compatibility  setting comes into help. Asp.net 4.0 compatibility settings provides full backward compatibility in terms of the rendering controls. You can assign this in your web.config section like following. XML, using GeSHi 1.0.8.6<system.web> <pages controlRenderingCompatibilityVersion="3.5|4.0"/> </system.web>  Parsed in 0.001 seconds at 84.92 KB/s Here the values of controlRenderingCompatibility is a string which will indicate on which way control should render in browser if you provide 4.0 then it will controls with more cleaner html and while if you want to go with old legacy rendering like 3.5 then you can put 3.5 and it will render same way as you are doing in asp.net 3.5. Hope this help you!!! Technorati Tags: ASP.NET 4.0,controlRenderingCompatibility

But now i want to include it as a subquery and it gives some errors i cant solve. Simplified example of use: select descriptions from ( WITH Orders(Id) AS ( SELECT DISTINCT anfrageid FROM MPHotlineAnfrageAnhang ) SELECT Id, ( SELECT CONVERT(VARCHAR(255),anfragetext) + ' | ' FROM MPHotlineAnfrageAnhang WHERE anfrageid = Id ORDER BY anfrageid, erstelltam FOR XML PATH('') ) AS Descriptions FROM Orders ) as tx where id=100012 Errors (Aproximate translation from spanish): -Incorrect sintaxis near 'WITH'. -Incorrect sintaxis near 'WITH'. If the instruction is a common table expression or a xmlnamespaces clause, the previous instruction must end with semicolon. -Incorrect sintaxis near ')'. What im doing wrong?

  • Common lisp error: "should be lambda expression"

    - by Zachary
    I just started learning Common Lisp a few days ago, and I'm trying to build a function that inserts a number into a tree. I'm getting an error, * - SYSTEM::%EXPAND-FORM: (CONS NIL LST) should be a lambda expression From googling around, it seems like this happens when you have too many sets of parenthesis, but after looking at this for an hour or so and changing things around, I can't figure out where I could be doing this. This is the code where it's happening: (defun insert (lst probe) (cond ((null lst) (cons probe lst)) ((equal (length lst) 1) (if (<= probe (first lst)) (cons probe lst) (append lst (list probe)))) ((equal (length lst) 2) ((cons nil lst) (append lst nil) (insertat nil lst 3) (cond ((<= probe (second lst)) (insert (first lst) probe)) ((> probe (fourth lst)) (insert (fifth lst) probe)) (t (insert (third lst) probe))))))) I'm pretty sure it's occurring after the ((equal (length lst) 2), where the idea is to insert an empty list into the existing list, then append an empty list onto the end, then insert an empty list into the middle.

  • Preventing multiple repeat selection of synchronized Controls ?

    - by BillW
    The working code sample here synchronizes (single) selection in a TreeView, ListView, and ComboBox via the use of lambda expressions in a dictionary where the Key in the dictionary is a Control, and the Value of each Key is an Action<int. Where I am stuck is that I am getting multiple repetitions of execution of the code that sets the selection in the various controls in a way that's unexpected : it's not recursing : there's no StackOverFlow error happening; but, I would like to figure out why the current strategy for preventing multiple selection of the same controls is not working. Perhaps the real problem here is distinguishing between a selection update triggered by the end-user and a selection update triggered by the code that synchronizes the other controls ? Note: I've been experimenting with using Delegates, and forms of Delegates like Action<T>, to insert executable code in Dictionaries : I "learn best" by posing programming "challenges" to myself, and implementing them, as well as studying, at the same time, the "golden words" of luminaries like Skeet, McDonald, Liberty, Troelsen, Sells, Richter. Note: Appended to this question/code, for "deep background," is a statement of how I used to do things in pre C#3.0 days where it seemed like I did need to use explicit measures to prevent recursion when synchronizing selection. Code : Assume a WinForms standard TreeView, ListView, ComboBox, all with the same identical set of entries (i.e., the TreeView has only root nodes; the ListView, in Details View, has one Column). private Dictionary<Control, Action<int>> ControlToAction = new Dictionary<Control, Action<int>>(); private void Form1_Load(object sender, EventArgs e) { // add the Controls to be synchronized to the Dictionary // with appropriate Action<int> lambda expressions ControlToAction.Add(treeView1, (i => { treeView1.SelectedNode = treeView1.Nodes[i]; })); ControlToAction.Add(listView1, (i => { listView1.Items[i].Selected = true; })); ControlToAction.Add(comboBox1, (i => { comboBox1.SelectedIndex = i; })); } private void synchronizeSelection(int i, Control currentControl) { foreach(Control theControl in ControlToAction.Keys) { // skip the 'current control' if (theControl == currentControl) continue; // for debugging only Console.WriteLine(theControl.Name + " synchronized"); // execute the Action<int> associated with the Control ControlToAction[theControl](i); } } private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { synchronizeSelection(e.Node.Index, treeView1); } private void listView1_SelectedIndexChanged(object sender, EventArgs e) { // weed out ListView SelectedIndexChanged firing // with SelectedIndices having a Count of #0 if (listView1.SelectedIndices.Count > 0) { synchronizeSelection(listView1.SelectedIndices[0], listView1); } } private void comboBox1_SelectedValueChanged(object sender, EventArgs e) { if (comboBox1.SelectedIndex > -1) { synchronizeSelection(comboBox1.SelectedIndex, comboBox1); } } background : pre C# 3.0 Seems like, back in pre C# 3.0 days, I was always using a boolean flag to prevent recursion when multiple controls were updated. For example, I'd typically have code like this for synchronizing a TreeView and ListView : assuming each Item in the ListView was synchronized with a root-level node of the TreeView via a common index : // assume ListView is in 'Details View,' has a single column, // MultiSelect = false // FullRowSelect = true // HideSelection = false; // assume TreeView // HideSelection = false // FullRowSelect = true // form scoped variable private bool dontRecurse = false; private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { if(dontRecurse) return; dontRecurse = true; listView1.Items[e.Node.Index].Selected = true; dontRecurse = false; } private void listView1_SelectedIndexChanged(object sender, EventArgs e) { if(dontRecurse) return // weed out ListView SelectedIndexChanged firing // with SelectedIndices having a Count of #0 if (listView1.SelectedIndices.Count > 0) { dontRecurse = true; treeView1.SelectedNode = treeView1.Nodes[listView1.SelectedIndices[0]]; dontRecurse = false; } } Then it seems, somewhere around FrameWork 3~3.5, I could get rid of the code to suppress recursion, and there was was no recursion (at least not when synchronizing a TreeView and a ListView). By that time it had become a "habit" to use a boolean flag to prevent recursion, and that may have had to do with using a certain third party control.

  • What's the official Microsoft way to track counts of dynamic controls to be reconstructed upon Postback?

    - by John K
    When creating dynamic controls based on a data source of arbitrary and changing size, what is the official way to track exactly how many controls need to be rebuilt into the page's control collection after a Postback operation (i.e. on the server side during the ASP.NET page event lifecycle) specifically the point at which dynamic controls are supposed to be rebuilt? Where is the arity stored for retrieval and reconstruction usage? By "official" I mean the Microsoft way of doing it. There exist hacks like Session storage, etc but I want to know the bonafide or at least Microsoft-recommended way. I've been unable to find a documentation page stating this information. Usually code samples work with a set of dynamic controls of known numbers. It's as if doing otherwise would be tougher. Update: I'm not inquiring about user controls or static expression of declarative controls, but instead about dynamically injecting controls completely from code-behind, whether they be mine, 3rd-party or built-in ASP.NET controls.

  • Finding all points common to two circles

    - by Dustin I.
    In Python, how would one find all points common to two circles? For example, imagine a Venn diagram-like intersection of two (equally sized) circles, with center-points (x1,y1) and (x2,y2) and radii r1=r2. Additionally, we already know the two points of intersection of the circles are (xi1,yi1) and (xi2,yi2). How would one generate a list of all points (x,y) contained in both circles in an efficient manner? That is, it would be simple to draw a box containing the intersections and iterate through it, checking if a given point is within both circles, but is there a better way?

  • function to find common rows between more than two data frames in R

    - by biohazard
    I have 4 data frames, and would like to find the rows whose values in a certain column do not exist in any of the other data frames. I wrote this function: #function to test presence of $Name in 3 other datasets common <- function(a, b, c, d) { is.B <- is.numeric(a$Name %in% b$Name) == 1 is.C <- is.numeric(a$Name %in% c$Name) == 1 is.D <- is.numeric(a$Name %in% d$Name) == 1 t <- as.numeric(is.B & is.C & is.D) t } However, the output is always t = 0. This means that it tells me that there are no unique rows in any data sets, even though the datas frames have very different numbers of rows. Since there are no duplicate rows in any of the data frames, I should be getting t = 1 for at least some rows in the biggest dataset. Can someone figure out what I got wrong?

  • Accessing parent-level controls from inside a ComboBox's child controls

    - by eponymous23
    I have XAML similar to this: <ListBox ItemsSource="{Binding SearchCriteria, Source={StaticResource model}}" SelectionChanged="cboSearchCriterionType_SelectionChanged"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Name="spCriterion" Orientation="Horizontal" Height="20"> <ComboBox Name="cboSearchCriterionType" Width="120" SelectionChanged="cboSearchCriterionType_SelectionChanged"> <ComboBox.Items> <ComboBoxItem IsSelected="True" Content="Anagram Match" /> <ComboBoxItem Content="Pattern Match" /> <ComboBoxItem Content="Subanagram Match" /> <ComboBoxItem Content="Length" /> <ComboBoxItem Content="Number of Vowels" /> <ComboBoxItem Content="Number of Anagrams" /> <ComboBoxItem Content="Number of Unique Letters" /> </ComboBox.Items> </ComboBox> <TextBox x:Name="SearchSpec" Text="{Binding SearchSpec}" /> <TextBox x:Name="MinValue" Text="{Binding MinValue}" Visibility="Collapsed" /> <TextBox x:Name="MaxValue" Text="{Binding MaxValue}" Visibility="Collapsed" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> As you can tell from the markup, I have a listbox that is bound to a collection of SearchCriterion objects (collectively contained in a SearchCriteria object). The idea is that the user can add/remove criterion items from the criteria, each criterion is represented by a listbox item. Inside the listbox item I have a combobox and three textboxes. What I'm trying to do is change the visibility of the TextBox controls depending on the item that is selected in the ComboBox. For example, if the user selects "Pattern Match" then I want to show only the first textbox and hide the latter two; conversely, if the user selects "Length" or any of the "Number of..." items, then I want to hide the first TextBox and show the latter two. What is the best way to achieve this? I was hoping to do something simple in the SelectionChanged event handler for the listbox but the textbox controls are presumably out of the SelectionChanged event's scope. Do I have to programmatically traverse the control hierarchy and find the controls?

    I have two methods f(vector<int>& x, ....) and g(DBConn& x, ....) where the (....) parameters are all identical. The code inside the two methods are completely identical except for one statement where we do different actions based on the type of x: in f(): we do x.push_back(i) in g(): we do x.DeleteRow(i) What is the simplest way to extract the common code into one method and yet have the two different statements? I am thinking of having a templated functor that overloads operator () (int a) but that seems overkill.

  • How to deal with configuration style warnings occuring from TexLive 2012 installation?

    - by JJD
    I followed the advice of izx on how to install TexLive 2012 using the texlive-backports PPA. Before I started I removed all TexLive-related packages. The installation finished and everything seems to work fine. The only thing I noticed are some warnings in the output of the installer. Here is an excerpt of the output: Warning: Old configuration style found in /etc/texmf/updmap.d Warning: For now these files have been included, Warning: but expect inconsistencies. Warning: These packages should be rebuild with tex-common. Warning: Please see /usr/share/doc/tex-common/NEWS.Debian.gz Warning: found file: /etc/texmf/updmap.d/10lmodern.cfg There are more of that kind in the rest of the output: $ sudo apt-get install texlive Reading package lists...
