  • 2 Shaders using the same vertex data

    - by Fonix
    So im having problems rendering using 2 different shaders. Im currently rendering shapes that represent dice, what i want is if the dice is selected by the user, it draws an outline by drawing the dice completely red and slightly scaled up, then render the proper dice over it. At the moment some of the dice, for some reason, render the wrong dice for the outline, but the right one for the proper foreground dice. Im wondering if they aren't getting their vertex data mixed up somehow. Im not sure if doing something like this is even allowed in openGL: glGenBuffers(1, &_vertexBuffer); glBindBuffer(GL_ARRAY_BUFFER, _vertexBuffer); glBufferData(GL_ARRAY_BUFFER, numVertices*sizeof(GLfloat), vertices, GL_STATIC_DRAW); glEnableVertexAttribArray(effect->vertCoord); glVertexAttribPointer(effect->vertCoord, 3, GL_FLOAT, GL_FALSE, 0, 0); glEnableVertexAttribArray(effect->toon_vertCoord); glVertexAttribPointer(effect->toon_vertCoord, 3, GL_FLOAT, GL_FALSE, 0, 0); im trying to bind the vertex data to 2 different shaders here when i load my first shader i have: vertCoord = glGetAttribLocation(TexAndLighting, "position"); and the other shader has: toon_vertCoord = glGetAttribLocation(Toon, "position"); if I use the shaders independently of each other they work fine, but when i try to render both one on top of the other they get the model mixed up some times. here is how my draw function looks: - (void) draw { [EAGLContext setCurrentContext:context]; glBindVertexArrayOES(_vertexArray); effect->modelViewMatrix = mvm; effect->numberColour = GLKVector4Make(numbers[colorSelected].r, numbers[colorSelected].g, numbers[colorSelected].b, 1); effect->faceColour = GLKVector4Make(faceColors[colorSelected].r, faceColors[colorSelected].g, faceColors[colorSelected].b, 1); if(selected){ [effect drawOutline]; //this function prepares the shader glDrawElements(GL_TRIANGLES, numIndices, GL_UNSIGNED_SHORT, 0); } [effect prepareToDraw]; //same with this one glDrawElements(GL_TRIANGLES, numIndices, GL_UNSIGNED_SHORT, 0); } this is what it looks like, as you can see most of the outlines are using the wrong dice, or none at all: links to full code: http://pastebin.com/yDKb3wrD Dice.mm //rendering stuff http://pastebin.com/eBK0pzrK Effects.mm //shader stuff http://pastebin.com/5LtDAk8J //my shaders, shouldn't be anything to do with them though TL;DR: trying to use 2 different shaders that use the same vertex data, but its getting the models mixed up when rendering using both at the same time, well thats what i think is going wrong, quite stumped actually.

  • java/swing: font size selection + rendering

    - by Jason S
    I want to create and fill/stroke a path that consists of an outer boundary which is a square of side d and an inner boundary that is the outline of any of the capital letters. How can I do this? (challenges = creating a mask from a font, and figuring out the right size/position to use)

  • Make openGL lines connected

    - by user146780
    Right now I'v created a polygon, then I do the same thing but with line_loop to draw the outline. My issue right now is if I set the line thickness to high, the lines arn't connected. Their ends would need to be (linewidth) longer... is there a way to fix this? Thanks

  • Setup and Use SpecFlow BDD with DevExpress XAF

    - by Patrick Liekhus
    Let’s get started with using the SpecFlow BDD syntax for writing tests with the DevExpress XAF EasyTest scripting syntax.  In order for this to work you will need to download and install the prerequisites listed below.  Once they are installed follow the steps outlined below and enjoy. Prerequisites Install the following items: DevExpress eXpress Application Framework (XAF) found here SpecFlow found here Liekhus BDD/XAF Testing library found here Assumptions I am going to assume at this point that you have created your XAF application and have your Module, Win.Module and Win ready for usage.  You should have also set any attributes and/or settings as you see fit. Setup So where to start. Create a new testing project within your solution. I typically call this with a similar naming convention as used by XAF, my project name .FunctionalTests (i.e. AlbumManager.FunctionalTests). Add the following references to your project.  It should look like the reference list below. DevExpress.Data.v11.x DevExpress.Persistent.Base.v11.x DevExpress.Persistent.BaseImpl.v11.x DevExpress.Xpo.v11.2 Liekhus.Testing.BDD.Core Liekhus.Testing.BDD.DevExpress TechTalk.SpecFlow TestExecutor.v11.x (found in %Program Files%\DevExpress 2011.x\eXpressApp Framework\Tools\EasyTest Right click the TestExecutor reference and set the “Copy Local” setting to True.  This forces the TestExecutor executable to be available in the bin directory which is where the EasyTest script will be executed further down in the process. Add an Application Configuration File (app.config) to your test application.  You will need to make a few modifications to have SpecFlow generate Microsoft style unit tests.  First add the section handler for SpecFlow and then set your choice of testing framework.  I prefer MS Tests for my projects. Add the EasyTest configuration file to your project.  Add a new XML file and call it Config.xml. Open the properties window for the Config.xml file and set the “Copy to Ouput Directory” to “Copy Always”. You will setup the Config file according to the specifications of the EasyTest library my mapping to your executable and other settings.  You can find the details for the configuration of EasyTest here.  My file looks like this Create a new folder in your test project called “StepDefinitions”.  Add a new SpecFlow Step Definition file item under the StepDefinitions folder.  I typically call this class StepDefinition.cs. Have your step definition inherit from the Liekhus.Testing.BDD.DevExpress.StepDefinition class.  This will give you the default behaviors for your test in the next section. OK.  Now that we have done this series of steps, we will work on simplifying this.  This is an early preview of this new project and is not fully ready for consumption.  If you would like to experiment with it, please feel free.  Our goals are to make this a installable project on it’s own with it’s own project templates and default settings.  This will be coming in later versions.  Currently this project is in Alpha release. Let’s write our first test Remove the basic test that is created for you. We will not use the default test but rather create our own SpecFlow “Feature” files. Add a new item to your project and select the SpecFlow Feature file under C#. Name your feature file as you do your class files after the test they are performing. Writing a feature file uses the Cucumber syntax of Given… When… Then.  Think of it in these terms.  Givens are the pre-conditions for the test.  The Whens are the actual steps for the test being performed.  The Thens are the verification steps that confirm your test either passed or failed.  All of these steps are generated into a an EasyTest format and executed against your XAF project.  You can find more on the Cucumber syntax by using the Secret Ninja Cucumber Scrolls.  This document has several good styles of tests, plus you can get your fill of Chuck Norris vs Ninjas.  Pretty humorous document but full of great content. My first test is going to test the entry of a new Album into the application and is outlined below. The Feature section at the top is more for your documentation purposes.  Try to be descriptive of the test so that it makes sense to the next person behind you.  The Scenario outline is described in the Ninja Scrolls, but think of it as test template.  You can write one test outline and have multiple datasets (Scenarios) executed against that test.  Here are the steps of my test and their descriptions Given I am starting a new test – tells our test to create a new EasyTest file And (Given) the application is open – tells EasyTest to open our application defined in the Config.xml When I am at the “Albums” screen – tells XAF to navigate to the Albums list view And (When) I click the “New:Album” button – tells XAF to click the New Album button on the ribbon And (When) I enter the following information – tells XAF to find the field on the screen and put the value in that field And (When) I click the “Save and Close” button – tells XAF to click the “Save and Close” button on the detail window Then I verify results as “user” – tells the testing framework to execute the EasyTest as your configured user Once you compile and prepare your tests you should see the following in your Test View.  For each of your CreateNewAlbum lines in your scenarios, you will see a new test ready to execute. From here you will use your testing framework of choice to execute the test.  This in turn will execute the EasyTest framework to call back into your XAF application and test your business application. Again, please remember that this is an early preview and we are still working out the details.  Please let us know if you have any comments/questions/concerns. Thanks and happy testing.

  • Behavior Driven Development (BDD) and DevExpress XAF

    - by Patrick Liekhus
    So in my previous posts I showed you how I used EDMX to quickly build my business objects within XPO and XAF.  But how do you test whether your business objects are actually doing what you want and verify that your business logic is correct?  Well I was reading my monthly MSDN magazine last last year and came across an article about using SpecFlow and WatiN to build BDD tests.  So why not use these same techniques to write SpecFlow style scripts and have them generate EasyTest scripts for use with XAF.  Let me outline and show a few things below.  I plan on releasing this code in a short while, I just wanted to preview what I was thinking. Before we begin… First, if you have not read the article in MSDN, here is the link to the article that I found my inspiration.  It covers the overview of BDD vs. TDD, how to write some of the SpecFlow syntax and how use the “Steps” logic to create your own tests. Second, if you have not heard of EasyTest from DevExpress I strongly recommend you review it here.  It basically takes the power of XAF and the beauty of your application and allows you to create text based files to execute automated commands within your application. Why would we do this?  Because as you will see below, the cucumber syntax is easier for business analysts to interpret and digest the business rules from.  You can find most of the information you will need on Cucumber syntax within The Secret Ninja Cucumber Scrolls located here.  The basics of the syntax are that Given X When Y Then Z.  For example, Given I am at the login screen When I enter my login credentials Then I expect to see the home screen.  Pretty easy syntax to follow. Finally, we will need to download and install SpecFlow.  You can find it on their website here.  Once you have this installed then let’s write our first test. Let’s get started… So where to start.  Create a new testing project within your solution.  I typically call this with a similar naming convention as used by XAF, my project name .FunctionalTests (i.e.  AlbumManager.FunctionalTests).  Remove the basic test that is created for you.  We will not use the default test but rather create our own SpecFlow “Feature” files.  Add a new item to your project and select the SpecFlow Feature file under C#.  Name your feature file as you do your class files after the test they are performing. Now you can crack open your new feature file and write the actual test.  Make sure to have your Ninja Scrolls from above as it provides valuable resources on how to write your test syntax.  In this test below you can see how I defined the documentation in the Feature section.  This is strictly for our purposes of readability and do not effect the test.  The next section is the Scenario Outline which is considered a test template.  You can see the brackets <> around the fields that will be filled in for each test.  So in the example below you can see that Given I am starting a new test and the application is open.  This means I want a new EasyTest file and the windows application generated by XAF is open.  Next When I am at the Albums screen tells XAF to navigate to the Albums list view.  And I click the New:Album button, tells XAF to click the new button on the list grid.  And I enter the following information tells XAF which fields to complete with the mapped values.  And I click the Save and Close button causes the record to be saved and the detail form to be closed.  Then I verify results tests the input data against what is visible in the grid to ensure that your record was created. The Scenarios section gives each test a unique name and then fills in the values for each test.  This way you can use the same test to make multiple passes with different data. Almost there.  Now we must save the feature file and the BDD tests will be written using standard unit test syntax.  This is all handled for you by SpecFlow so just save the file.  What you will see in your Test List Editor is a unit test for each of the above scenarios you just built. You can now use standard unit testing frameworks to execute the test as you desire.  As you would expect then, these BDD SpecFlow tests can be automated into your build process to ensure that your business requirements are satisfied each and every time. How does it work? What we have done is to intercept the testing logic at runtime to interpret the SpecFlow syntax into EasyTest syntax.  This is the basic StepDefinitions that we are working on now.  We expect to put these on CodePlex within the next few days.  You can always override and make your own rules as you see fit for your project.  Follow the MSDN magazine above to start your own.  You can see part of our implementation below. As you can gather from the MSDN article and the code sample below, we have created our own common rules to build the above syntax. The code implementation for these rules basically saves your information from the feature file into an EasyTest file format.  It then executes the EasyTest file and parses the XML results of the test.  If the test succeeds the test is passed.  If the test fails, the EasyTest failure message is logged and the screen shot (as captured by EasyTest) is saved for your review. Again we are working on getting this code ready for mass consumption, but at this time it is not ready.  We will post another message when it is ready with all details about usage and setup. Thanks

  • Cannot Expand/Collapse tasks in Microsoft Project 2010

    - by Dean
    I opened an existing Microsoft Project file today and was unable to expand/collapse the subtasks use the cursor and the '+/-' signs beside the parent tasks. I am able to expand and collapse using the 'View-Outline' ribbon icon. However when I attempt to do this using the mouse on specific tasks, my cursor will not perform the task. My cursor is a 'white cross' when I need it to be an 'arrow'. I'm assuming this is something minor that I'm missing. Any assistance appreciated. Thanks

  • OpenGL ES 2 shaders for drawing buildings and roads like Google Maps does

    - by Pris
    I'm trying to create a shader that'll give me an effect similar to what buildings and roads look like on 3D Google Maps. You can see the effect interactively if you enable WebGL at maps.google.com, and I also found a couple of screenshots that illustrate what I'm trying to achieve: Thing I noticed: There's some kind of transparency thing going on with the roads/ground and the buildings, but not between the buildings themselves. It might be that they're rendering the ground and roads after the buildings with the right blend functions to achieve that effect. If you look closely, you'll see parts of the building profiles have an outline. The roads also have nice clean outlines. There are a lot of techniques for outlining things with shaders... but I'm curious to find out what might have been used in this case considering mobile hardware and a large number of entities with outlines (roads and buildings) I'm assuming that for the lighting, some sort of simple diffuse per-vertex shader is being used for the buildings though I could be wrong. I'm especially curious about the 'look' they achieved with buildings (clean, precise outlines/shading). It reminds me a little of what you'd see when designing stuff with CAD applications like SolidWorks: I'd appreciate any advice on achieving this kind of look with ES 2 shaders.

  • Questions, Knowledge Checks and Assessments

    - by ted.henson
    Questions should be used to reinforce concepts throughout the title. You have the option to include questions in the course, in assessments, in Knowledge Checks, or in any combination. Questions are required for creating knowledge checks and assessments. It is important to remember that questions that are not in assessments are not tracked. Be sure to structure your outline so that questions are added to the appropriate assignable unit. I usually recommend that questions appear directly below their relative section. This serves two purposes. First, it helps ensure that the related content and question stay relative to one another. Secondly, it ensures that when the "link to subject" option is used it will relate back to the relative content. Knowledge checks are created using the questions that have been added to the related assignable unit. Use Knowledge Checks to give users an additional opportunity to review what they have learned. Knowledge Check allows users to check their own knowledge without being tracked or scored. Many users like having this self check option, especially if they know they are going to be tested later. Each assignable unit can have its own Knowledge Check. Assessments provide a way to measure knowledge or understanding of the course material. The results of each assessment are scored and tracked. Assessments are created using the questions that have been added to the relative assignable unit(s). Each assignable unit, including the Title AU, can have multiple assessments. Consider how your knowledge paths will be structured when planning your assessments. For instance, you can create a multiple-activity knowledge path, with multiple assessments from the same title or assignable unit. Also remember, in Manager an assessment can be either a pre or post assessment. Pre-assessments allow the student to discover what is already known in a specific topic or subject and important if the personal course feature is being used. Post-assessments allow you test the student knowledge or understanding after completing the material.

  • xp vpn client dns issue

    - by David Archer
    Hi All, I have a problem with dns when connected to my work vpn. For ease of explanation I'll use the following in my outline of the problem: - name of my machine on work network is REMOTE_XP (original i know) - ip of my machine on work network is 192.168.2.80 - name of my machine on my local network is LOCAL_XP - ip of my machine on my local network is 10.0.0.3 What I want to be able to do when connected to vpn: - browse the internet from LOCAL_XP - ping by name REMOTE_XP Now it seems I've so far mentioned either 1 but not both of my wishlist. If i go to my vpn network properties (on LOCAL_XP) and uncheck the "use default dns on remote network" then I can browse the internet from my local machine but can't ping REMOTE_XP (though I can ping 192.168.2.80) If I check "use default dns..." then I can ping REMOTE_XP but can't browse the internet from LOCAL_XP. Is there a way I can have my dns cake and eat it, or will I have to accept that it will be an either/or situation? Thanks in advance.

  • Are there any font rendering libraries for games development that support hinting?

    - by Richard Fabian
    I've used angel code's bitmap font generator quite a bit and though it's very good, I wondered if there would be a way of using the hinting information to provide a better readable result by using hinting to provide differing thickness based on size/pixel coverage. I imagine any solution would have to use the distance field tech presented in the valve paper on smoothing fonts while maintaining or reducing asset size. (http://www.gamedev.net/community/forums/topic.asp?topic_id=494612) but I haven't found any demos of it being used with hinting information turned on or included in the field gradients in any way. Another way of looking at this is whether there are any font bitmap generators that will output mipmaps that still maintain their readability in the face of pixel size. I think the lower mip levels would try to guarantee fill and space where it is necessary to maintain readability/topology over maintaining style/form (the point of hinting). In response to "Is there a reason you can't just render the size you want", the problem lies in the fact that font rasterisers currently don't render in 3D, and hinting information would be important in different amounts due to the pixel density being different along different axes, even differing in importance along the length of a string due to the size reducing over distance. For example, I only want horizontal hinting in a texture that is viewed from the side, and only really want vertical hinting in a font that is viewed from below or above. This isn't meant to be a renderer that tries to render a perfect outline as accurately as possible, as hinting distorts the reality of the font, instead this is meant to be a rendering solution for quite static scenes, but scenes that have 3D transformed and warped text layout. In this case the legibility is important, more important than the accuracy of representation of the polygon shape.

  • preparing to migrate MOSS 2007 SP1 content into new server with MOSS 2007 SP2 with the same server n

    - by Albert Widjaja
    To All Experts here, I'd like to perform a MOSS server content migration from the existing single instance server (SQL Server 2008, Windows Server 2008, SharePoint 2007 SP1) all in one and by maintaining the server name only, here's what I had in my migration plan document outline: I have created the new Windows Server 2008 R2 + SQL Server 2008 SP1 and MOSS 2007 SP2 after that: Backup MOSS_ContentDB from SQL Server 2008 SSMS (does this enough to cover all top level sites and its content in the library and doc. repository ?) Backup all top level sites from CA site using the CA Sites backup and restore tools. turn off the old MOSSDEV01 (current server) rename the existing server (TempServ01) into MOSSDEV01 (so that the user bookmark and other link inside MOSS site still working) perform restore of the DB restore the site collection and its content from the backup is that the correct way to do it ? I haven't execute the server configuration wizard to create the same port number of the SSP, CA and the SQL Server DB yet. Any idea and suggestion would be greatly appreciated Thanks.

  • A WPF Image Button

    - by psheriff
    Instead of a normal button with words, sometimes you want a button that is just graphical. Yes, you can put an Image control in the Content of a normal Button control, but you still have the button outline, and trying to change the style can be rather difficult. Instead I like creating a user control that simulates a button, but just accepts an image. Figure 1 shows an example of three of these custom user controls to represent minimize, maximize and close buttons for a borderless window. Notice the highlighted image button has a gray rectangle around it. You will learn how to highlight using the VisualStateManager in this blog post.Figure 1: Creating a custom user control for things like image buttons gives you complete control over the look and feel.I would suggest you read my previous blog post on creating a custom Button user control as that is a good primer for what I am going to expand upon in this blog post. You can find this blog post at http://weblogs.asp.net/psheriff/archive/2012/08/10/create-your-own-wpf-button-user-controls.aspx.The User ControlThe XAML for this image button user control contains just a few controls, plus a Visual State Manager. The basic outline of the user control is shown below:<Border Grid.Row="0"        Name="borMain"        Style="{StaticResource pdsaButtonImageBorderStyle}"        MouseEnter="borMain_MouseEnter"        MouseLeave="borMain_MouseLeave"        MouseLeftButtonDown="borMain_MouseLeftButtonDown">  <VisualStateManager.VisualStateGroups>  ... MORE XAML HERE ...  </VisualStateManager.VisualStateGroups>  <Image Style="{StaticResource pdsaButtonImageImageStyle}"         Visibility="{Binding Path=Visibility}"         Source="{Binding Path=ImageUri}"         ToolTip="{Binding Path=ToolTip}" /></Border>There is a Border control named borMain and a single Image control in this user control. That is all that is needed to display the buttons shown in Figure 1. The definition for this user control is in a DLL named PDSA.WPF. The Style definitions for both the Border and the Image controls are contained in a resource dictionary names PDSAButtonStyles.xaml. Using a resource dictionary allows you to create a few different resource dictionaries, each with a different theme for the buttons.The Visual State ManagerTo display the highlight around the button as your mouse moves over the control, you will need to add a Visual State Manager group. Two different states are needed; MouseEnter and MouseLeave. In the MouseEnter you create a ColorAnimation to modify the BorderBrush color of the Border control. You specify the color to animate as “DarkGray”. You set the duration to less than a second. The TargetName of this storyboard is the name of the Border control “borMain” and since we are specifying a single color, you need to set the TargetProperty to “BorderBrush.Color”. You do not need any storyboard for the MouseLeave state. Leaving this VisualState empty tells the Visual State Manager to put everything back the way it was before the MouseEnter event.<VisualStateManager.VisualStateGroups>  <VisualStateGroup Name="MouseStates">    <VisualState Name="MouseEnter">      <Storyboard>        <ColorAnimation             To="DarkGray"            Duration="0:0:00.1"            Storyboard.TargetName="borMain"            Storyboard.TargetProperty="BorderBrush.Color" />      </Storyboard>    </VisualState>    <VisualState Name="MouseLeave" />  </VisualStateGroup></VisualStateManager.VisualStateGroups>Writing the Mouse EventsTo trigger the Visual State Manager to run its storyboard in response to the specified event, you need to respond to the MouseEnter event on the Border control. In the code behind for this event call the GoToElementState() method of the VisualStateManager class exposed by the user control. To this method you will pass in the target element (“borMain”) and the state (“MouseEnter”). The VisualStateManager will then run the storyboard contained within the defined state in the XAML.private void borMain_MouseEnter(object sender,  MouseEventArgs e){  VisualStateManager.GoToElementState(borMain,    "MouseEnter", true);}You also need to respond to the MouseLeave event. In this event you call the VisualStateManager as well, but specify “MouseLeave” as the state to go to.private void borMain_MouseLeave(object sender, MouseEventArgs e){  VisualStateManager.GoToElementState(borMain,     "MouseLeave", true);}The Resource DictionaryBelow is the definition of the PDSAButtonStyles.xaml resource dictionary file contained in the PDSA.WPF DLL. This dictionary can be used as the default look and feel for any image button control you add to a window. <ResourceDictionary  ... >  <!-- ************************* -->  <!-- ** Image Button Styles ** -->  <!-- ************************* -->  <!-- Image/Text Button Border -->  <Style TargetType="Border"         x:Key="pdsaButtonImageBorderStyle">    <Setter Property="Margin"            Value="4" />    <Setter Property="Padding"            Value="2" />    <Setter Property="BorderBrush"            Value="Transparent" />    <Setter Property="BorderThickness"            Value="1" />    <Setter Property="VerticalAlignment"            Value="Top" />    <Setter Property="HorizontalAlignment"            Value="Left" />    <Setter Property="Background"            Value="Transparent" />  </Style>  <!-- Image Button -->  <Style TargetType="Image"         x:Key="pdsaButtonImageImageStyle">    <Setter Property="Width"            Value="40" />    <Setter Property="Margin"            Value="6" />    <Setter Property="VerticalAlignment"            Value="Top" />    <Setter Property="HorizontalAlignment"            Value="Left" />  </Style></ResourceDictionary>Using the Button ControlOnce you make a reference to the PDSA.WPF DLL from your WPF application you will see the “PDSAucButtonImage” control appear in your Toolbox. Drag and drop the button onto a Window or User Control in your application. I have not referenced the PDSAButtonStyles.xaml file within the control itself so you do need to add a reference to this resource dictionary somewhere in your application such as in the App.xaml.<Application.Resources>  <ResourceDictionary>    <ResourceDictionary.MergedDictionaries>      <ResourceDictionary         Source="/PDSA.WPF;component/PDSAButtonStyles.xaml" />    </ResourceDictionary.MergedDictionaries>  </ResourceDictionary></Application.Resources>This will give your buttons a default look and feel unless you override that dictionary on a specific Window or User Control or on an individual button. After you have given a global style to your application and you drag your image button onto a window, the following will appear in your XAML window.<my:PDSAucButtonImage ... />There will be some other attributes set on the above XAML, but you simply need to set the x:Name, the ToolTip and ImageUri properties. You will also want to respond to the Click event procedure in order to associate an action with clicking on this button. In the sample code you download for this blog post you will find the declaration of the Minimize button to be the following:<my:PDSAucButtonImage       x:Name="btnMinimize"       Click="btnMinimize_Click"       ToolTip="Minimize Application"       ImageUri="/PDSA.WPF;component/Images/Minus.png" />The ImageUri property is a dependency property in the PDSAucButtonImage user control. The x:Name and the ToolTip we get for free. You have to create the Click event procedure yourself. This is also created in the PDSAucButtonImage user control as follows:private void borMain_MouseLeftButtonDown(object sender,  MouseButtonEventArgs e){  RaiseClick(e);}public delegate void ClickEventHandler(object sender,  RoutedEventArgs e);public event ClickEventHandler Click;protected void RaiseClick(RoutedEventArgs e){  if (null != Click)    Click(this, e);}Since a Border control does not have a Click event you will create one by using the MouseLeftButtonDown on the border to fire an event you create called “Click”.SummaryCreating your own image button control can be done in a variety of ways. In this blog post I showed you how to create a custom user control and simulate a button using a Border and Image control. With just a little bit of code to respond to the MouseLeftButtonDown event on the border you can raise your own Click event. Dependency properties, such as ImageUri, allow you to set attributes on your custom user control. Feel free to expand on this button by adding additional dependency properties, change the resource dictionary, and even the animation to make this button look and act like you want.NOTE: You can download the sample code for this article by visiting my website at http://www.pdsa.com/downloads. Select “Tips & Tricks”, then select “A WPF Image  Button” from the drop down list.

  • Is Openness at the heart of the EU Digital Agenda?

    - by trond-arne.undheim
    At OpenForum Europe Summit 2010, to be held in Brussels, Autoworld, 11 Parc du Cinquantenaire on Thursday 10 June 2010, a number of global speakers will discuss whether it indeed provides an open digital market as a catalyst for economic growth and if it will deliver a truly open e-government and digital citizenship (see Summit 2010). In 2008, OpenForum Europe, a not-for-profit champion of openness through open standards, hosted one of the most cited speeches by Neelie Kroes, then Commissioner of Competition. Her forward-looking speech on openness and interoperability as a way to improve the competitiveness of ICT markets set the EU on a path to eradicate lock-in forever. On the two-year anniversary of that event, Vice President Kroes, now the first-ever Commissioner of the Digital Agenda, is set to outline her plans for delivering on that vision. Much excitement surrounds open standards, given that Kroes is a staunch believer. The EU's Digital Agenda promises IT standardization reform in Europe and vows to recognize global standards development organizations (fora/consortia) by 2010. However, she avoided the term "open standards" in her new strategy. Markets are, of course, asking why she is keeping her cards tight on this crucial issue. Following her speech, Professor Yochai Benkler, award-winning author of "The Wealth of Networks", and Professor Nigel Shadbolt, appointed by the UK Government to work alongside Sir Tim Berners-Lee to help transform public access to UK Government information join dozens of speakers in the quest to analyse, entertain and challenge European IT policy, people, and documents. Speakers at OFE Summit 2010 include David Drummond, Senior VP Corporate Development and Chief Legal Officer, Google; Michael Karasick, VP Technology and Strategy, IBM; Don Deutsch, Vice President, Standards Strategy and Architecture for Oracle Corp; Thomas Vinje, Partner Clifford Chance; Jerry Fishenden, Director, Centre for Policy Research, and Rishab Ghosh, head, collaborative creativity group, UNU-MERIT, Maastricht (see speakers). Will openness stay at the heart of EU Digital Agenda? Only time will show.

  • Documenting and enforcing programming standards and guidelines for shared library

    - by dreza
    Myself and another developer with the go ahead from our IT director have started a general purpose library in .NET with the intention that it will provide many common purpose classes that we use in our day to day development. During discussions and design of the library we have come up with a set of standards that we want the library to follow to ensure it is maintained and expanded on in a consistent manner. What is the best way to ensure these decisions we made for the library get feed to the other developers who might be using and adding to this library in the future. One of our decisions was to ensure we review all checked in code so we expect initially there to be some differences in coding styles of individuals not fitting in with the project standards. Some ideas I had were: Add a Read-me.txt to the project that outline the guidelines and standards Send an email out to everyone in the team to let them know about the project etc Call a team meeting to go through this new project and our expectations and standards we were aiming to follow Try and enforce the standards via Visual Studio (not sure if this would be possible or how just an idea) At the moment there is no general company programming standards so this would be a first really insofar as we are creating a standard that different project teams would need to adhere to.

  • How to become a professional web developer from a C/C++ programmer?

    - by user1050165
    I am new here. This is my first post on stackoverflow. I am currently a high school student and know how to use Pascal and C/C++ to take part in competitions such as the Informatics in Olympiad. I have learnt data structure and many algorithms to solve various kinds of problems. Now, I want to move on to become a web developer. However, I know web development is quite different from competitive programming. To make a web application, I have to master HTML, Database, Backend programming etc. But these are all look like separate pieces of information. I don't know where to start and what order should I follow. Anybody who can give a comprehensive list of learning points? I know there are HTML, Ruby on Rails, CSS and Javascript. What else? More importantly, can someone give a brief outline of their relationship? I hope I can get help from you asap. Thanks!

  • How to switch to user perspective in Blender

    - by Cyanophage
    I've just started using Blender (v2.63) for the first time. I have used a lot of 3d modelling programs in the past but Blender's controls seem to be set up differently and it's taking a while to get used to it. The thing that is really bugging me at the moment is switching from user perspective to front/side/top views. I have my view in perspective mode and I want to switch to front view in orthographic mode and then switch back to the view I had before. It seems that the only way is to press numpad-0 to go to camera view, rotate the screen a bit to get rid of the annoying black outline and then switch it back to perspective mode. Then sometimes when I go back to front view it's in perspective mode which is annoying as you never want front view in perspective, only orthographic mode. My question: Is there a way I can be in my user view in perspective mode, switch to front/side/top views in orthographic mode and then switch back to where I was before in my user mode and be back in perspective mode?
