  • How to avoid circular relationship in SQL-Server?

    - by Shimmy
    I am creating a self-related table: Table Item columns: ItemId int - PK; Amount money - not null; Price money - a computed column using a UDF that retrieves value according to the items ancestors' Amount. ParentItemId int - nullable, reference to another ItemId in this table. I need to avoid a loop, meaning, a sibling cannot become an ancestor of his ancestors, meaning, if ItemId=2 ParentItemId = 1, then ItemId 1 ParentItemId = 2 shouldn't be allowed. I don't know what should be the best practice in this situation. I think I should add a CK that gets a Scalar value from a UDF or whatever else. EDIT: Another option is to create an INSTEAD OF trigger and put in 1 transaction the update of the ParentItemId field and selecting the Price field from the @@RowIdentity, if it fails cancel transaction, but I would prefer a UDF validating. Any ideas are sincerely welcomed.

  • How to enable HTTP response caching in Spring Boot

    - by Samuli Kärkkäinen
    I have implemented a REST server using Spring Boot 1.0.2. I'm having trouble preventing Spring from setting HTTP headers that disable HTTP caching. My controller is as following: @Controller public class MyRestController { @RequestMapping(value = "/someUrl", method = RequestMethod.GET) public @ResponseBody ResponseEntity<String> myMethod( HttpServletResponse httpResponse) throws SQLException { return new ResponseEntity<String>("{}", HttpStatus.OK); } } All HTTP responses contain the following headers: Cache-Control: no-cache, no-store, max-age=0, must-revalidate Expires: 0 Pragma: no-cache I've tried the following to remove or change those headers: Call setCacheSeconds(-1) in the controller. Call httpResponse.setHeader("Cache-Control", "max-age=123") in the controller. Define @Bean that returns WebContentInterceptor for which I've called setCacheSeconds(-1). Set property spring.resources.cache-period to -1 or a positive value in application.properties. None of the above have had any effect. How do I disable or change these headers for all or individual requests in Spring Boot?

  • Find largest rectangle containing all zero's in an N X N binary matrix

    - by Rajendra
    Given an N X N binary matrix (containing only 0's or 1's). How can we go about finding largest rectangle containing all 0's? Example: I 0 0 0 0 1 0 0 0 1 0 0 1 II->0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 <--IV 0 0 1 0 0 0 IV is a 6 X 6 binary matrix, return value in this case will be Cell 1: (2, 1) and Cell 2: (4, 4). Resulting sub-matrix can be square or rectangle. Return value can be size of the largest sub-matrix of all 0's also, for example, here 3 X 4.

  • Hide ticks at Min and Max in WPF Slider

    - by gehho
    Hi, I want to display a Slider ranging from 0.5 to 1.5 with only one tick mark at 1.0 to mark the center and default value. I have defined a Slider as follows: <Slider Minimum="0.5" Maximum="1.5" IsMoveToPointEnabled="True" IsSnapToTickEnabled="False" Orientation="Horizontal" Ticks="1.0" TickPlacement="BottomRight" Value="{Binding SomeProperty, Mode=TwoWay}"/> However, besides a tick mark at 0.0 this Slider also shows tick marks at 0.5 and 1.5, i.e. the Minimum and Maximum values. Is there a way to hide these min/max tick marks?! I checked all properties and tried changing some of them, but did not have success so far. Thanks, gehho.

  • Viewstate is setting control values incorrectly.

    - by Praesagus
    I have a page with several checkboxes on it. The checkboxes correlate to user permissions so when I change users and the page refreshes, the values of the checkboxes should change since each user is different. In spite of the fact that my code sets the value of the checkbox, viewstate or whatever changes the values to what the previous user's values were. I tried chk.EnableViewState = false; but that did not help. I set EnableViewState="false" EnableViewStateMac="false" EnableEventValidation="false" in the page directives, but that doesn't help. The only way I have been able to fix this is to add a unique value to the controls so that their names are always different. I am sure it's an issue of ignorance. Thank you for your help. There is no databinding per se. When the page loads I am creating the textboxes and setting their values via code.

  • Inspecting Lucene.NET index with Luke want to replicate NHibernate.Search view

    - by Tim Peel
    Hi, I am trying to put together an index using terms, which I specify as a comma separated list. I want to replicate the display in Luke as seen here: http://ayende.com/Blog/archive/2009/05/03/nhibernate-search-again.aspx But my index value just shows as a single field with the comma separate list value. For example: Tags term,anotherterm When I search my index, it will return results if I search with "term" but will not return anything if I search with "anotherterm" I thought the indexing process would break the comma separate list apart into separate values but this does not seem to be the case. Anyone got any ideas? Thanks

  • Simple P2V help from Linux to Windows

    - by Ke.
    I have two OS's installed on different drives in my PC. One linux (Centos 5.4) and one windows 7. Its getting tiresome to constantly have to stop and restart the PC when I want to use either OS. I would very much like to use Windows 7 as my host OS and access my linux OS from within Windows. However, im having trouble deciphering exactly how to do this (many of the articles seem confusing and a bit overkill) From what i have seen its possible to use VMWare converter to convert the physical linux image to a virtual image so that I can use it in windows. As im having problems understanding how this is done, I would really appreciate a step by step guide (for a newbie), or any simple tutorials that you can point me at. Some questions beforehand: 1) My linux image is around 80gb, do i need to take this into consideration? The linux drive is around 180gb in total. All my other drives are NTFS non writeable in linux (as I use them in windows and ntfs is dodgy in linux), so probably not possible to move the image over to my ntfs drives 2) Can I just zip the linux files up somehow and transfer it to windows to create the p2v? 3) Is it possible to do the P2V conversion while I am logged into windows. I can see the actual linux drive loaded in disk manager, but windows doesnt read linux file systems so im confused as to how to access the linux drive if this is possible. 4) Or will i need to do the whole p2v conversion inside linux? Cheers, any help is much appreciated Ke (a confused p2v newbie)

  • Edit TabControl template in Silverlight project

    - by philbrowndotcom
    I'm trying to modify the template for the TabControl in my silverlight application. I used Expression Blend to get the Template and copied it into my project. I did this before for Expander and got it to work with a few minor adjustments. The template for TabControl references the ns/assembly "clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls" and uses the TabPanel control from it. I can't seem to make a reference to this. I'm using silverlight 3 and .NET 3 Thanks <UserControl.Resources> <ControlTemplate x:Key="mytemplate" TargetType="sdk:TabControl"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualStateGroup.Transitions> <VisualTransition GeneratedDuration="0"/> </VisualStateGroup.Transitions> <VisualState x:Name="Normal"/> <VisualState x:Name="Disabled"> <Storyboard> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Opacity" Storyboard.TargetName="DisabledVisualTop"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualBottom"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualLeft"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualRight"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid x:Name="TemplateTop" Visibility="Collapsed"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelTop" Margin="2,2,2,-1" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0,0,3,3" MinWidth="10" MinHeight="10" Grid.Row="1"> <ContentPresenter x:Name="ContentTop" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualTop" Background="#8CFFFFFF" CornerRadius="0,0,3,3" IsHitTestVisible="False" Opacity="0" Grid.Row="1" Grid.RowSpan="2" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateBottom" Visibility="Collapsed"> <Grid.RowDefinitions> <RowDefinition Height="*"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelBottom" Margin="2,-1,2,2" Grid.Row="1" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="3,3,0,0" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentBottom" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualBottom" Background="#8CFFFFFF" CornerRadius="3,3,0,0" IsHitTestVisible="False" Opacity="0" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateLeft" Visibility="Collapsed"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelLeft" Margin="2,2,-1,2" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Column="1" CornerRadius="0,3,3,0" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentLeft" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualLeft" Background="#8CFFFFFF" Grid.Column="1" CornerRadius="0,3,3,0" IsHitTestVisible="False" Opacity="0" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateRight" Visibility="Collapsed"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelRight" Grid.Column="1" Margin="-1,2,2,2" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="3,0,0,3" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentRight" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualRight" Background="#8CFFFFFF" CornerRadius="3,0,0,3" IsHitTestVisible="False" Margin="0" Opacity="0" Canvas.ZIndex="1"/> </Grid> </Grid> </ControlTemplate> </UserControl.Resources>

  • MVC2 DataAnnotations validation with inheritance

    - by bhiku
    Hi, I have a .NET 2.0 class the properties of which are marked virtual.I need to use the class as a model in a MVC2 application. So, I have created a .NET 3.5 class inheriting from the .NET 2.0 class and added the DataAnnotations attributes to the overriden properties in the new class. A snippet of what I have done is below // .NET 2.0 class public class Customer { private string _firstName = ""; public virtual string FirstName { get { return _firstName; } set { _firstName = value; } } } // .NET 3.5 class public class MVCCustomer : Customer { [Required(ErrorMessage="Firstname is required")] public override string FirstName { get { return base.FirstName; } set { base.FirstName = value; } } } I have used the class as the model for a MVC2 view using the HtmlFor helpers. Serverside validation works correctly but the client side validation does not. Specifically the validation error is not displayed on the page. What am I missing, or is it only possible to do this using buddy classes. Thanks.

  • availability of Win32_MountPoint and Win32_Volume on Windows XP?

    - by SteveC
    From the MSDN articles I've found -- http://msdn.microsoft.com/en-us/library/aa394515(v=VS.85).aspx -- Win32_Volume and Win32_MountPoint aren't available on Windows XP. However, I'm developing a C# app on Windows XP (64bit), and I can get to those WMI classes just fine. Users of my app will be on Windows XP sp2 with .Net 3.5 sp1. Googling around, I can't determine whether I can count on this or not. Am I successful on my system because of one or more of the following: - windows xp service pack 2? - visual studio 2008 sp1 was installed? - .Net 3.5 sp1? Should I use something other than WMI to get at the volume/mountpoint info? Below is sample code that's working... public static Dictionary<string, NameValueCollection> GetAllVolumeDeviceIDs() { Dictionary<string, NameValueCollection> ret = new Dictionary<string, NameValueCollection>(); // retrieve information from Win32_Volume try { using (ManagementClass volClass = new ManagementClass("Win32_Volume")) { using (ManagementObjectCollection mocVols = volClass.GetInstances()) { // iterate over every volume foreach (ManagementObject moVol in mocVols) { // get the volume's device ID (will be key into our dictionary) string devId = moVol.GetPropertyValue("DeviceID").ToString(); ret.Add(devId, new NameValueCollection()); //Console.WriteLine("Vol: {0}", devId); // for each non-null property on the Volume, add it to our NameValueCollection foreach (PropertyData p in moVol.Properties) { if (p.Value == null) continue; ret[devId].Add(p.Name, p.Value.ToString()); //Console.WriteLine("\t{0}: {1}", p.Name, p.Value); } // find the mountpoints of this volume using (ManagementObjectCollection mocMPs = moVol.GetRelationships("Win32_MountPoint")) { foreach (ManagementObject moMP in mocMPs) { // only care about adding directory // Directory prop will be something like "Win32_Directory.Name=\"C:\\\\\"" string dir = moMP["Directory"].ToString(); // find opening/closing quotes in order to get the substring we want int first = dir.IndexOf('"') + 1; int last = dir.LastIndexOf('"'); string dirSubstr = dir.Substring(first , last - first); // use GetFullPath to normalize/unescape any extra backslashes string fullpath = Path.GetFullPath(dirSubstr); ret[devId].Add(MOUNTPOINT_DIRS_KEY, fullpath); } } } } } } catch (Exception ex) { Console.WriteLine("Problem retrieving Volume information from WMI. {0} - \n{1}",ex.Message,ex.StackTrace); return ret; } return ret; }

  • Best way of implementing DropDownList in ASP.NET MVC 2?

    - by Kelsey
    I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question. First, what is the best way to pass the list data to the view? Pass the list in your model with a SelectList property that contains the data Pass the list in via ViewData How do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value? Lastly, if for some reason there is a server side error and I need to redisplay the screen with the DropDownList, do I need to fetch the list values again to pass into the view model? This data is not maintained between posts (at least not when I pass it via my view model) so I was going to just fetch it again (it's cached). Am I going about this correctly?

  • How to use a App.config file in WPF applications?

Does anyone know how to use config files like this in WPF?

  • Choosing between Berkeley DB Core and Berkeley DB JE

    - by zokier
    I'm designing a Java based web-app and I need a key-value store. Berkeley DB seems fitting enough for me, but there appears to be TWO Berkeley DBs to choose from: Berkeley DB Core which is implemented in C, and Berkeley DB Java Edition which is implemented in pure Java. The question is, how to choose which one to use? With web-apps scalability and performance is quite important (who knows, maybe my idea will become the next Youtube), and I couldn't find easily any meaningful benchmarks between the two. I have yet to familiarize with Cores Java API, but I find it hard to believe that it could be much worse than Java Editions, which seems to be quite nice. If some other key-value store would be much better, feel free to recommend that too. I'm storing smallish binary blobs, and keys probably will be hashes of the data, or some other unique id.

  • ASP.NET MVC Get a list of users with particular profile properties

    - by Sam Huggill
    Hi, I'm using ASP.NET MVC 1 and I have added a custom Profile class using the WebProfile Builder VS add-in (found here: http://code.msdn.microsoft.com/WebProfileBuilder/Release/ProjectReleases.aspx?ReleaseId=980). On one of my forms I want a drop-down list of all users who share a specific profile value in common. I can see that I can get a list of all users using: Membership.GetAllUsers() However I cannot see how to get all users who have a specific profile value, which in my case is CellId. Am I approaching this in the right way? I have used membership roles to define which users are administrators etc, but profiles seems like the right place to group users. Any pointers both in specifics of how to access the user list but also comments on whether am I pursuing the right avenue here would be greatly appreciated. Many thanks, Sam

  • Wire VMWare Player NIC to a VLAN in Ubuntu 8.04.3

    - by Sophie Charlesworth
    Hi, I've got VMWare Player 2.5.x installed on a Ubuntu 8.04.3 host running CentOS 5.3 running Cobbler. VMWare Player has two NICs (I actually took this image from an ESXi image, converted it to Player 2.x image via VMWare Standalone Converter). I've also setup a vlan (vlan5) on the host with 10.0.0.x and I'd like Cobbler to use that VLAN to serve any incoming requests. How do I wire up my VMWare to use the VLAN I've setup? Just one of the NICs. What I'm trying to do is to offer a laptop with a VM that our sysadmins can go, plug it into a box (which does not connect to the interwebs) and install RHEL images via cobbler. So essentially, its a cross over cable from the network port on the lappy to the Dell server box. PXE boot in the dell box and install RHEL. I have the cobbler working fine under VMWare ESXi but not so on the VMWare Player because of the VLAN issue - I think. Any ideas?

  • WPF TextBox trigger to clear Text

    - by PaN1C_Showt1Me
    Hi ! I have many TextBox controls and I'm trying to write a style that clears the Text property when the Control is disabled. I don't want to have Event Handlers in code behind. I wrote this: <Style TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Text" Value="{x:Null}" /> </Trigger> </Style.Triggers> </Style> The problem is that if the TextBox is defined like: <TextBox Text={Binding Whatever} /> then the trigger does not work (probably because it's bound) How to overcome this problem?

  • What is The Loop Variable After a For Loop in Delphi?

    - by Andreas Rejbrand
    In Delphi, consider var i: integer; begin for i := 0 to N do begin { Code } end; One might think that i = N after the for loop, but does the Delphi compiler guarantee this? Can one make the assumption that the loop variable is equal to its last value inside the loop, after a Delphi if loop? Update After trying a few simple loops, I suspect that i is actually equal to one plus the last value of i inside the loop after the loop... But can you rely on this?

  • Remove all html tags from attributes in rails

    - by Hock
    I have a Project model and it has some text attributes, one is summary. I have some projects that have html tags in the summary and I want to convert that to plain text. I have this method that has a regex that will remove all html tags. def strip_html_comments_on_data self.attributes.each{|key,value| value.to_s.gsub!(/(<[^>]+>|&nbsp;|\r|\n)/,"")} end I also have a before_save filter before_save :strip_html_comments_on_data The problem is that the html tags are still there after saving the project. What am I missing? And, is there a really easy way to have that method called in all the models? Thanks, Nicolás Hock Isaza

  • Monitoring disk performance with MRTG

    - by Ghostrider
    I use MRTG to monitor vital stats on my servers like disk space, CPU load, memory usage, temperatures etc. It all works fine and well for parameters that don't change rapidly. By running small VB script I can also get any Performance Counter. However these scripts are called by MRTG every 5 minutes while performance counters like physical disk idle time return a snapshot value from previous few seconds so a lot or data is missed. Surely I could write a service that would poll all required counters in background and store average values somewhere on disk where MRTG would pick them up. However before I do so I would like to find out if there is some ready solution that would allow me to get average value of some counter for the last 5 minutes as opposed to immediate snapshot.

  • WCF- Large Data

    - by Pinu
    I have a WCF Web Service with basicHTTPBinding , the server side the transfer mode is streamedRequest as the client will be sending us large file in the form of memory stream. But on client side when i use transfer mode as streamedRequest its giving me a this errro "The remote server returned an error: (400) Bad Request" And when i look in to trace information , i see this as the error message Exception: There is a problem with the XML that was received from the network. See inner exception for more details. InnerException: The body of the message cannot be read because it is empty. I am able to send up to 5MB of data using trasfermode as buffered , but it will effect the performance of my web service in the long run , if there are many clients who are trying to access the service in buffered transfer mode.

  • django - dynamic form fieldsets

    - by user110029
    A form will be spitting out an unknown number of questions to be answered. each question contains a prompt, a value field, and a unit field. The form is built at runtime in the formclass's init method. I'd like each question rendered on the form as an inline: prompt, value(input-text), units (select). this seems a case perfect for iterable form fieldsets, which could be easily styled. but since fieldsets - such as those in django-form-utils are defined as tuples, they are immutable... and I can't find a way to define them at runtime. is this possible, or perhaps another solution?

  • FluentNhibernate IDictionary<Entity,ValueObject>

    - by Miguel Marques
    I had a mapping for a IDictionary<StocksLocation,decimal> property, this was the mapping: HasMany<StocksLocation>(mq => mq.StocksLocation) .KeyColumn("IDProduct") .AsEntityMap("IDLocation") .Element("Quantity", qt => qt.Type<decimal>()); Now i changed from decimal to a Value Object: Quantity. Quantity has two properties, decimal Value and Unit Unit (where Unit is an enum). I now have to map IDictionary<StocksLocation,Quantity>, how can i achieve this? Thanks in advance
