  • MDI and WPF Ribbon

    - by femi

I want to create an instance such that once i click on one of the WPF Buttons, i am taken to a different XAML UserControl or "page". How do i do this? Will this new page have the WPF Ribbon on the top? thanks

  • Sharing transactions between web applications, which run in the same cluster

    - by pihentagy
    We (will) have the following architecture: Base.war will be a self-contained spring-hibernate application All applications will run under Glassfish, and may be clustered E1.war will sit on top of Base.war, extending it's functionality There could be further extensions (E2.war, E3.war, …) sitting on top of Base.war Either wars could start a transaction, and transactions could span between wars Without shutting down Base.war, or any other Ex.war, it should be possible to upgrade an Ey.war Is there a solution for this with spring-hibernate-glassfish environment?

  • Any significant performance improvement by using bitwise operators instead of plain int sums in C#?

    - by tunnuz
    Hello, I started working with C# a few weeks ago and I'm now in a situation where I need to build up a "bit set" flag to handle different cases in an algorithm. I have thus two options: enum RelativePositioning { LEFT = 0, RIGHT = 1, BOTTOM = 2, TOP = 3, FRONT = 4, BACK = 5 } pos = ((eye.X < minCorner.X ? 1 : 0) << RelativePositioning.LEFT) + ((eye.X > maxCorner.X ? 1 : 0) << RelativePositioning.RIGHT) + ((eye.Y < minCorner.Y ? 1 : 0) << RelativePositioning.BOTTOM) + ((eye.Y > maxCorner.Y ? 1 : 0) << RelativePositioning.TOP) + ((eye.Z < minCorner.Z ? 1 : 0) << RelativePositioning.FRONT) + ((eye.Z > maxCorner.Z ? 1 : 0) << RelativePositioning.BACK); Or: enum RelativePositioning { LEFT = 1, RIGHT = 2, BOTTOM = 4, TOP = 8, FRONT = 16, BACK = 32 } if (eye.X < minCorner.X) { pos += RelativePositioning.LEFT; } if (eye.X > maxCorner.X) { pos += RelativePositioning.RIGHT; } if (eye.Y < minCorner.Y) { pos += RelativePositioning.BOTTOM; } if (eye.Y > maxCorner.Y) { pos += RelativePositioning.TOP; } if (eye.Z > maxCorner.Z) { pos += RelativePositioning.FRONT; } if (eye.Z < minCorner.Z) { pos += RelativePositioning.BACK; } I could have used something as ((eye.X > maxCorner.X) << 1) but C# does not allow implicit casting from bool to int and the ternary operator was similar enough. My question now is: is there any performance improvement in using the first version over the second? Thank you Tommaso

  • Deletes not cascading for self-referencing entities

    - by jwaddell
    I have the following (simplified) Hibernate entities: @Entity @Table(name = "package") public class Package { protected Content content; @OneToOne(cascade = {javax.persistence.CascadeType.ALL}) @JoinColumn(name = "content_id") @Fetch(value = FetchMode.JOIN) public Content getContent() { return content; } public void setContent(Content content) { this.content = content; } } @Entity @Table(name = "content") public class Content { private Set<Content> subContents = new HashSet<Content>(); private ArchivalInformationPackage parentPackage; @OneToMany(fetch = FetchType.EAGER) @JoinTable(name = "subcontents", joinColumns = {@JoinColumn(name = "content_id")}, inverseJoinColumns = {@JoinColumn(name = "elt")}) @Cascade(value = {org.hibernate.annotations.CascadeType.DELETE, org.hibernate.annotations.CascadeType.REPLICATE}) @Fetch(value = FetchMode.SUBSELECT) public Set<Content> getSubContents() { return subContents; } public void setSubContents(Set<Content> subContents) { this.subContents = subContents; } @ManyToOne(cascade = {CascadeType.ALL}) @JoinColumn(name = "parent_package_id") public Package getParentPackage() { return parentPackage; } public void setParentPackage(Package parentPackage) { this.parentPackage = parentPackage; } } So there is one Package, which has one "top" Content. The top Content links back to the Package, with cascade set to ALL. The top Content may have many "sub" Contents, and each sub-Content may have many sub-Contents of its own. Each sub-Content has a parent Package, which may or may not be the same Package as the top Content (ie a many-to-one relationship for Content to Package). The relationships are required to be ManyToOne (Package to Content) and ManyToMany (Content to sub-Contents) but for the case I am currently testing each sub-Content only relates to one Package or Content. The problem is that when I delete a Package and flush the session, I get a Hibernate error stating that I'm violating a foreign key constraint on table subcontents, with a particular content_id still referenced from table subcontents. I've tried specifically (recursively) deleting the Contents before deleting the Package but I get the same error. Is there a reason why this entity tree is not being deleted properly? EDIT: After reading answers/comments I realised that a Content cannot have multiple Packages, and a sub-Content cannot have multiple parent-Contents, so I have modified the annotations from ManyToOne and ManyToMany to OneToOne and OneToMany. Unfortunately that did not fix the problem. I have also added the bi-directional link from Content back to the parent Package which I left out of the simplified code.

  • IE8 positioning, nightmare!

    - by Kyle Sevenoaks
    Well hi, guess what, I have an IE positioning issue! This is in 8, so god know what's going on in the other versions (checking later) Both the boxes call the same class, why is IE being so difficult? Here's how it's meant to look: And here's how it does look: CSS: (removed comments for ease of reading) div .roundbigboxkunde { background-image:url(../../upload/EW_kunde_info.png); background-position:top center; padding:10px; padding-top:10px; padding-bottom:20px; width:560px; height:1%; border-width:1px; border-color:#dddddd; border-radius:10px; -moz-border-radius:10px; -webkit-border-radius:10px; z-index:1; position:relative; overflow:hidden; } div .roundbigboxkundei { margin-top:10px; padding:10px; padding-top:10px; padding-bottom:10px; width:760px; height:1%; position:relative; overflow:hidden; And HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <div class="roundbigboxkunde"> <div class="roundbigboxkundei"> <p id="nyk">&nbsp;</p> <div id="bg_box2"></div> <p class="required"> <label for="billing_firstName"><span class="label">Fornavn:</span></label> <fieldset class="error"><input name="billing_firstName" class="text" type="text" value="Kyle"/> <div class="errorText hidden"></div> </fieldset> </p> CONTENT CONTINUES </fieldset> Here is the page

  • Plane projection and scale causing bluring in silverlight

    - by Andy
    Ok, So I've tried to make an application which relies on images being scaled by an individual factor. These images are then able to be turned over, but the use of an animation working on the ProjectionPlane rotation. The problem comes around when an image is both scaled and rotated. For some reason it starts bluring, where a non scaled image doesn't blur. Also, if you look at the example image below (top is scaled and rotated, bottom is rotated) the projection of the top one doesn't even seem right. Its too horizontal. This this the code for the test app: <UserControl x:Class="SilverlightApplication1.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <Canvas x:Name="LayoutRoot" Background="White"> <Border Canvas.Top="25" Canvas.Left="50"> <Border.RenderTransform> <TransformGroup> <ScaleTransform ScaleX="3" ScaleY="3" /> </TransformGroup> </Border.RenderTransform> <Border.Projection> <PlaneProjection RotationY="45"/> </Border.Projection> <Image Source="bw-test-pattern.jpg" Width="50" Height="40"/> </Border> <Border Canvas.Top="150" Canvas.Left="50"> <Border.RenderTransform> <TransformGroup> <ScaleTransform ScaleX="1" ScaleY="1" /> </TransformGroup> </Border.RenderTransform> <Border.Projection> <PlaneProjection RotationY="45"/> </Border.Projection> <Image Source="bw-test-pattern.jpg" Width="150" Height="120"/> </Border> </Canvas> </UserControl> So if anyone could possible shed any light on why this may be happening, I'd very much appreciate it. Suggestions also welcome! :)

  • CSS: background image does not fill when scrolling

    - by rekindleMyLoveOf
    Hi, working on a very small site which loads in one go, so there is a div which holds all the background images, and on top of that (i.e. higher z-index) there is a content div which holds everything. I can switch backgrounds easily based on what content is selected. Unfortunately, I noticed if you launch in a small window so that scrollbars appear, if you scroll there is no background image in the 'revealed' portions of the page. :-( Page structure: <body> <div id="bg"> <div class="bgone"></div> <div class="bgtwo"></div> </div> <div id="container"> <!-- content panels here --> </div> </body> css: #bg { margin: 0px; position: absolute; top: 0px; left: 0px; width:100%; height: 1024px; z-index:1; } .bgone { margin: 0px; position: absolute; width:100%; height: 1024px; background-image:url(../images/one.jpg); background-position:top; background-repeat:repeat-x; z-index:2; } .bgtwo { margin: 0px; position: absolute; width:100%; height: 1024px; background-image:url(../images/two.jpg); background-position:top; background-repeat:repeat-x; z-index:3; } #container { position:relative; width:900px; padding:0px; margin:0px auto; height:600px; z-index:10; }

  • wpf and win32 overlapping issue

    - by priya-hatipkar
    I have a wpf Window, which has wpf control and windows forms control hosted in WindowsFormsHost. The expected behavior is that the WPF control should be rendered on top of WindowsFormsHost. Unfortunately, this is a limitation in the interop story, WindowsFormsHost elements are always drawn on top, and don't get affected by z-order. http://msdn.microsoft.com/en-us/library/ms742522.aspx Is there any workaround to solve this problem?

  • Sticky Footer Dilemma - so close

    - by fmz
    I have an effective sticky footer solution, but I have a slight conflict because of the need for a background image in addition to the repeating banner image across the top. In order to make the large watermark type image show up on this site I added the following div: <div id="body-outer"> The only problem is that once I add this div tag, the footer climbs up the page, overriding all content in its path. If I remove that div, the footer is as sticky as one could hope. Is there some way to have the background image and the sticky footer too? Here is the basic html structure: <body class="home"> <div id="body-outer"> <div id="container"> <div id="header"> ... <div id="footer"> <p>Placeholder for footer content</p> </div> Here is the css for the sticky footer and the background image: #body-outer { background: url(../_images/bg_body.jpg) no-repeat center top; height: 100%; } body { width: 100%; background: url(../_images/bg_html.jpg) repeat-x left top; } #container { width: 960px; margin: 0 auto; } html, body, #container { height: 100%; } body > #container { height: auto; min-height: 100%; padding-bottom: 140px; } #main { padding-bottom: 0; } #footer { position: relative; width: 100%; background-color: #4e8997; margin-top: ; /* negative value of footer height */ height: 140px; clear:both; } .clearfix:after { content: "."; display: block; height: 0; clear: both; visibility: hidden; } .clearfix {display: inline-block;} * html .clearfix { height: 1%;} Any assistance in sorting this out would be greatly appreciated. thanks.

  • Relative silverlight control positioning

    - by george9170
    I Have a canvas and would like to place silverlight elements within that canvas relative to each. For example, I have an element (A) at canvas.top="0" canvas.left="5". I would like to place all elements proceeding that one relative to its position. So if i move A to canvas.top="10" canvas.left="15" all other elements would reposition themselves. IF this is feasibly with a canvas let me know, else can you recommend what control i should be using. Thank you very much

  • CSS Child selectors in IE7 tables

    - by John
    I'm trying to use the CSS child selector in IE7, and it doesn't seem to work. I have nested tables. My outer table has a class name "mytable", and I want the td's of the outer table to show borders. I don't want the inner table td's to have borders. I think I should be able to have CSS that looks like this: .mytable { border-style: solid } .mytable>tr>td { border-style: solid } But the second line seems to have no effect. If I change the second line to make it less specific, it applies to all the td's - I see too many borders. td { border-style: solid } So I think it really is just an issue with the selectors. Pages like this suggest that IE7 should be able to do what I want. Am I doing something silly? Here's the whole HTML file: <html> <head> <style type="text/css"> .mytable { border-style: solid; border-collapse: collapse;} td { border-style: solid; } </style> </head> <body> <table class="mytable"> <tr> <td>Outer top-left</td> <td>Outer top-right</td> </tr> <tr> <td>Outer bottom-left</td> <td> <table> <tr> <td>Inner top-left</td> <td>Inner top-right</td> </tr> <tr> <td>Inner bottom-left</td> <td>Inner bottom-right</td> </tr> <table> </td> </tr> <table> </body> </html>

  • Design-time failure: WPF, Usercontrols and Namespaces

    - by Simon Woods
    Hi I have a very simple WPF project comprising a Window and Usercontrol. I'm very much in a learning phase. It works fine when I run it. However, I am unable to see the form in design time. The problem, I believe is something to do with namespaces, but I don't understand where. It may well be a simple error Main Window XML <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:views="clr-namespace:UserLogin" x:Class="UserLogin.MainView" x:Name="MainViewWindow" mc:Ignorable="d" Title="Login" Height="141" Width="347" > <Grid> <views:LoginView /> </Grid> </Window> Main Window CodeBehind Imports Microsoft.VisualBasic Imports System Imports System.Windows Imports UserLogin Namespace UserLogin Partial Public Class MainView Inherits System.Windows.Window Public Sub New() InitializeComponent() End Sub End Class End Namespace Usercontrol XAML <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" x:Class="UserLogin.LoginView" x:Name="LoginViewControl" mc:Ignorable="d" d:DesignHeight="96" d:DesignWidth="298"> <Grid Height="96" Width="298"> <Button Command="{Binding OKCommand}" Height="21" Margin="0,0,90,16" Name="btnOK" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="76">OK</Button> <Button Command="{Binding CancelCommand}" Height="21" HorizontalAlignment="Right" Margin="0,0,9,16" Name="btnCancel" VerticalAlignment="Bottom" Width="75">Cancel</Button> <Label Height="23" HorizontalAlignment="Left" Margin="10,5,0,0" Name="Label1" VerticalAlignment="Top" Width="85">Name:</Label> <Label HorizontalAlignment="Left" Margin="10,32,0,0" Name="Label2" Width="85" Height="29" VerticalAlignment="Top">Password:</Label> <TextBox Margin="0,31,6,0" Name="txtPassword" Height="22" VerticalAlignment="Top" HorizontalAlignment="Right" Width="182" /> <ComboBox Height="22" Margin="110,6,6,0" Name="cboNames" VerticalAlignment="Top" /> </Grid> </UserControl> Usercontrol CodeBehind Imports Microsoft.VisualBasic Imports System Imports UserLogin Namespace UserLogin Partial Public Class LoginView Inherits System.Windows.Controls.UserControl Public Sub New() InitializeComponent() End Sub End Class End Namespace I think I'm missing something this namespace xmlns:views="clr-namespace:UserLogin" since intellisense doesn't give me the usercontrol declared within it in the XAML designer but rather reports the error "Unable to load the metadata for the assembly ... etc etc" Thx for any suggestions Simon
