  • STARTTLS issues with sendmail

    - by Jim
    I just switch hosts and now have to configure sendmail with certificates in order to send mail. Is there anyone here that can point me to some solid documentation that is known to work? I'm on CentOS, using sendmail 8.13. I am currently trying to figure out why I am getting "Relaying denied. Proper authentication required". I'd be happy to post my mc file if someone thinks thay can help..

  • How to install fink when behind proxy?

    - by Mad Fish
    I'm having a Mac computer at work, and the internet connection is through HTTP proxy. I want to install fink (or macports, doesn't really matter), to have all the useful utilities (like mc). I've set the proxy during fink installation. It has successfully installed, but "fink selfupdate" cannot download using rsync (using cvs it fails too). What can I do?

  • Is it possible to modify/rebuild an rpm without the srpm?

    - by warren
    I have an rpm for which I need to change the preinstal scriptlet for testing. However, I do not have the SRPM from which is was built. Is it possible to change the scriptlet and/or rebuild the rpm without having the SRPM? If so, how? I've tried using Midnight Commander (mc) to open the rpm as a directory structure and edit the contents, but even with 444 permissions, it won't let me save any changes.

  • When OneTug Just Isn&rsquo;t Enough&hellip;

    - by onefloridacoder
    I stole that from the back of a T-shirt I saw at the Orlando Code Camp 2010.  This was my first code camp and my first time volunteering for an event like this as well.  It was an awesome day.  I cannot begin to count the “aaahh”, “I did-not-know I could do that”, in the crowds and for myself.  I think it was a great day of learning for everyone at all levels.  All of the presenters were different and provided great insights into the topics they were presenting.  Here’s a list of the ones that I attended. KodeFuGuru, “Pirates vs. Ninjas” He touched on many good topics to relax some of the ways we think when we are writing out code, and still looks good, readable, etc.  As he pointed out in all of his examples, we might not always realize everything that’s going on under the covers.  He exposed a bug in his own code, and verbalized the mental gymnastics he went through when he knew there was something wrong with one of his IEnumerable implementations.  For me, it was great to hear that someone else labors over these gut reactions to code quickly snapped together, to the point that we rush to the refactor stage to fix what’s bothering us – and learn.  He has some content on extension methods that was very interesting.  My “that is so cool” moment was when he swapped out AddEntity method on an entity class and used a With extension method instead.  Some of the LINQ scales fell off my eyes at that moment, and I realized my own code could be a lot more powerful (and readable) if incorporate a few of these examples at the appropriate times.  And he cautioned as well… “don’t go crazy with this stuff”, there’s a place and time for everything.  One of his examples demo’d toward the end of the talk is on his sight where he’s chaining methods together, cool stuff. Quotes I liked: “Extension Methods - Extension methods to put features back on the model type, without impacting the type.” “Favor Declarative Code” – Check out the ? and ?? operators if you’re not already using them. “Favor Fluent Code” “Avoid Pirate Ninja Zombies!  If you see one run!” I’m definitely going to be looking at “Extract Projection” when I get into VS2010. BDD 101 – Sean Chambers http://github.com/schambers This guy had a whole host of gremlins against him, final score Sean 5, Gremlins 1.  He ran the code samples from his github repo  in the code github code viewer since the PC they school gave him to use didn’t have VS installed. He did a great job of converting the grammar between BDD and TDD, and how this style of development can be used in integration tests as well as the different types of gated builds on a CI box – he didn’t go into a discussion around CI, but we could infer that it could work. Like when we use WSSF, it does cause a class explosion to happen however the amount of code per class it limit to just covering the concern at hand – no more, no less.  As in “When I as a <Role>, expect {something} to happen, because {}”  This keeps us (the developer) from gold plating our solutions and creating less waste.  He basically keeps the code that prove out the requirement to two lines of code.  Nice. He uses SpecUnit to merge this grammar into his .NET projects and gave an overview on how this ties into writing his own BDD tests.  Some folks were familiar with Given / When / Then as story acceptance criteria and here’s how he mapped it: “Given <Context>  When <Something Happens> Then <I expect...>”  There are a few base classes and overrides in the SpecUnit framework that help with setting up the context for each test which looked very handy. Successfully Running Your Own Coding Business The speaker ran through a list of items that sounded like common sense stuff LLC, banking, separating expenses, etc.  Then moved into role playing with business owners and an ISV.  That was pretty good stuff, it pays to be a good listener all of the time even if your client is sitting on the other side of the phone tearing you head off for you – but that’s all it is, and get used to it its par for the course.  Oh, yeah always answer the phone was one simple thing that you can do to move  your business forward.  But like Cory Foy tweeted this week, “If you owe me a lot of money, don’t have a message that says your away for five weeks skiing in Colorado.”  Lots of food for thought that’s on my list of “todo’s and to-don’ts”. Speaker Idol Next, I had the pleasure of helping Russ Fustino tape this part of Code Camp as my primary volunteer opportunity that day.  You remember Russ, “know the code” from the awesome Russ’ Tool Shed series.  He did a great job orchestrating and capturing the Speaker Idol finals.   So I didn’t actually miss any sessions, but was able to see three back to back in one setting.  The idol finalists gave a 10 minute talk and very deep subjects, but different styles of talks.  No one walked away empty handed for jobs very well done.  Russ has details on his site.  The pictures and  video captured is supposed to be published on Channel 9 at a later date.  It was also a valuable experience to see what makes technical speakers effective in their talks.  I picked up quite a few speaking tips from what I heard from the judges and contestants. Design For Developers – Diane Leeper If you are a great developer, you’re probably a lousy designer.  Diane didn’t come to poke holes in what we think we can do with UI layout and design, but she provided some tools we can use to figure out metaphors for visualizing data.  If you need help with that check out Silverlight Pivot – that’s what she was getting at.  I was first introduced to her at one of John Papa’s talks last year at a Lakeland User Group meeting and she’s very passionate about design.  She was able to discuss different elements of Pivot, while to a developer is just looked cool. I believe she was providing the deck from her talk to folks after her talk, so send her an email if you’re interested.   She says she can talk about design for hours and hours – we all left that session believing her.   Rinse and Repeat Orlando Code Camp 2010 was awesome, and would totally do it again.  There were lots of folks from my shop there, and some that have left my shop to go elsewhere.  So it was a reunion of sorts and a great celebration for the simple fact that its great to be a developer and there’s a community that supports and recognizes it as well.  The sponsors were generous and the organizers were very tired, namely Esteban Garcia and Will Strohl who were responsible for making a lot of this magic happen.  And if you don’t believe me, check out the chatter on Twitter.

  • Security in Software

    The term security has many meanings based on the context and perspective in which it is used. Security from the perspective of software/system development is the continuous process of maintaining confidentiality, integrity, and availability of a system, sub-system, and system data. This definition at a very high level can be restated as the following: Computer security is a continuous process dealing with confidentiality, integrity, and availability on multiple layers of a system. Key Aspects of Software Security Integrity Confidentiality Availability Integrity within a system is the concept of ensuring only authorized users can only manipulate information through authorized methods and procedures. An example of this can be seen in a simple lead management application.  If the business decided to allow each sales member to only update their own leads in the system and sales managers can update all leads in the system then an integrity violation would occur if a sales member attempted to update someone else’s leads. An integrity violation occurs when a team member attempts to update someone else’s lead because it was not entered by the sales member.  This violates the business rule that leads can only be update by the originating sales member. Confidentiality within a system is the concept of preventing unauthorized access to specific information or tools.  In a perfect world the knowledge of the existence of confidential information/tools would be unknown to all those who do not have access. When this this concept is applied within the context of an application only the authorized information/tools will be available. If we look at the sales lead management system again, leads can only be updated by originating sales members. If we look at this rule then we can say that all sales leads are confidential between the system and the sales person who entered the lead in to the system. The other sales team members would not need to know about the leads let alone need to access it. Availability within a system is the concept of authorized users being able to access the system. A real world example can be seen again from the lead management system. If that system was hosted on a web server then IP restriction can be put in place to limit access to the system based on the requesting IP address. If in this example all of the sales members where accessing the system from the 192.168.1.23 IP address then removing access from all other IPs would be need to ensure that improper access to the system is prevented while approved users can access the system from an authorized location. In essence if the requesting user is not coming from an authorized IP address then the system will appear unavailable to them. This is one way of controlling where a system is accessed. Through the years several design principles have been identified as being beneficial when integrating security aspects into a system. These principles in various combinations allow for a system to achieve the previously defined aspects of security based on generic architectural models. Security Design Principles Least Privilege Fail-Safe Defaults Economy of Mechanism Complete Mediation Open Design Separation Privilege Least Common Mechanism Psychological Acceptability Defense in Depth Least Privilege Design PrincipleThe Least Privilege design principle requires a minimalistic approach to granting user access rights to specific information and tools. Additionally, access rights should be time based as to limit resources access bound to the time needed to complete necessary tasks. The implications of granting access beyond this scope will allow for unnecessary access and the potential for data to be updated out of the approved context. The assigning of access rights will limit system damaging attacks from users whether they are intentional or not. This principle attempts to limit data changes and prevents potential damage from occurring by accident or error by reducing the amount of potential interactions with a resource. Fail-Safe Defaults Design PrincipleThe Fail-Safe Defaults design principle pertains to allowing access to resources based on granted access over access exclusion. This principle is a methodology for allowing resources to be accessed only if explicit access is granted to a user. By default users do not have access to any resources until access has been granted. This approach prevents unauthorized users from gaining access to resource until access is given. Economy of Mechanism Design PrincipleThe Economy of mechanism design principle requires that systems should be designed as simple and small as possible. Design and implementation errors result in unauthorized access to resources that would not be noticed during normal use. Complete Mediation Design PrincipleThe Complete Mediation design principle states that every access to every resource must be validated for authorization. Open Design Design PrincipleThe Open Design Design Principle is a concept that the security of a system and its algorithms should not be dependent on secrecy of its design or implementation Separation Privilege Design PrincipleThe separation privilege design principle requires that all resource approved resource access attempts be granted based on more than a single condition. For example a user should be validated for active status and has access to the specific resource. Least Common Mechanism Design PrincipleThe Least Common Mechanism design principle declares that mechanisms used to access resources should not be shared. Psychological Acceptability Design PrincipleThe Psychological Acceptability design principle refers to security mechanisms not make resources more difficult to access than if the security mechanisms were not present Defense in Depth Design PrincipleThe Defense in Depth design principle is a concept of layering resource access authorization verification in a system reduces the chance of a successful attack. This layered approach to resource authorization requires unauthorized users to circumvent each authorization attempt to gain access to a resource. When designing a system that requires meeting a security quality attribute architects need consider the scope of security needs and the minimum required security qualities. Not every system will need to use all of the basic security design principles but will use one or more in combination based on a company’s and architect’s threshold for system security because the existence of security in an application adds an additional layer to the overall system and can affect performance. That is why the definition of minimum security acceptably is need when a system is design because this quality attributes needs to be factored in with the other system quality attributes so that the system in question adheres to all qualities based on the priorities of the qualities.

  • Android: who can help me with setting up this google maps class please??

    - by Capsud
    Hi, Firstly this has turned out to be quite a long post so please bear with me as its not too difficult but you may need to clarify something with me if i haven't explained it correctly. So with some help the other day from guys on this forum, i managed to partially set up my 'mapClass' class, but i'm having trouble with it and its not running correctly so i would like some help if possible. I will post the code below so you can see. What Ive got is a 'Dundrum' class which sets up the listView for an array of items. Then ive got a 'dundrumSelector' class which I use to set up the setOnClickListener() methods on the listItems and link them to their correct views. DundrumSelector class.. public static final int BUTTON1 = R.id.anandaAddressButton; public static final int BUTTON2 = R.id.bramblesCafeAddressButton; public static final int BUTTON3 = R.id.brannigansAddressButton; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); int position = getIntent().getExtras().getInt("position"); if(position == 0){ setContentView(R.layout.ananda); }; if(position == 1){ setContentView(R.layout.bramblescafe); }; if(position == 2){ setContentView(R.layout.brannigans); Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); myIntent.putExtra("button", BUTTON1); startActivityForResult(myIntent,0); } }); Button bramblesbutton = (Button) findViewById(R.id.bramblesCafeAddressButton); bramblesbutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); myIntent.putExtra("button", BUTTON2); startActivityForResult(myIntent, 0); } }); etc etc.... Then what i did was set up static ints to represent the buttons which you can see at the top of this class, the reason for this is because in my mapClass activity I just want to have one method, because the only thing that is varying is the coordinates to each location. ie. i dont want to have 100+ map classes essentially doing the same thing other than different coordinates into the method. So my map class is as follows... case DundrumSelector.BUTTON1: handleCoordinates("53.288719","-6.241179"); break; case DundrumSelector.BUTTON2: handleCoordinates("53.288719","-6.241179"); break; case DundrumSelector.BUTTON3: handleCoordinates("53.288719","-6.241179"); break; } } private void handleCoordinates(String l, String b){ mapView = (MapView) findViewById(R.id.mapView); LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom); View zoomView = mapView.getZoomControls(); zoomLayout.addView(zoomView, new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mapView.displayZoomControls(true); mc = mapView.getController(); String coordinates[] = {l, b}; double lat = Double.parseDouble(coordinates[0]); double lng = Double.parseDouble(coordinates[1]); p = new GeoPoint( (int) (lat*1E6), (int) (lng*1E6)); mc.animateTo(p); mc.setZoom(17); mapView.invalidate(); } Now this is where my problem is. The onClick() events don't even work from the listView to get into the correct views. I have to comment out the methods in 'DundrumSelector' before I can get into their views. And this is what I dont understand, firstly why wont the onClick() events work, because its not even on that next view where the map is. I know this is a very long post and it might be quite confusing so let me know if you want any clarification.. Just to recap, what i'm trying to do is just have one class that sets up the map coordinates, like what i'm trying to do in my 'mapClass'. Please can someone help or suggest another way of doing this! Thanks alot everyone for reading this.

  • Blending the Sketchflow Action

    - by GeekAgilistMercenary
    Started a new Sketchflow Prototype in Expression Blend recently and documented each of the steps.  This blog entry covers some of those steps, which are the basic elements of any prototype.  I will have more information regarding design, prototype creation, and the process of the initial phases for development in the future.  For now, I hope you enjoy this short walk through.  Also, be sure to check out my last quick entry on Sketchflow. I started off with a Sketchflow Project, just like I did in my previous entry (more specifics in that entry about how to manipulate and build out the Sketchflow Map). Once I created the project I setup the following Sketchflow Map. The CoreNavigation is a ComponentScreen setup solely for the page navigation at the top of the screen.  The XAML markup in case you want to create a Component Screen with the same design is included below. <UserControl 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" mc:Ignorable="d" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:pb="clr-namespace:Microsoft.Expression.Prototyping.Behavior;assembly=Microsoft.Expression.Prototyping.Interactivity" x:Class="RapidPrototypeSketchScreens.CoreNavigation" d:DesignWidth="624" d:DesignHeight="49" Height="49" Width="624">   <Grid x:Name="LayoutRoot"> <TextBlock HorizontalAlignment="Stretch" Margin="307,3,0,0" Style="{StaticResource TitleCenter-Sketch}" Text="Aütøchart Scorecards" TextWrapping="Wrap"> <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonDown"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1"/> </i:EventTrigger> </i:Interaction.Triggers> </TextBlock> <Button HorizontalAlignment="Left" Margin="164,8,0,11" Style="{StaticResource Button-Sketch}" Width="144" Content="Scorecard"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1_2"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> <Button HorizontalAlignment="Left" Margin="8,8,0,11" Style="{StaticResource Button-Sketch}" Width="152" Content="Standard Reports"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1_1"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> </Grid> </UserControl> Now that the CoreNavigation Component Screen is done I built out each of the others.  In each of those screens I included the CoreNavigation Screen (all those little green lines in the image) as the top navigation.  In order to do that, as I created each of the pages I would hover over the CoreNavigation Object in the Sketchflow Map.  When the utilities drawer (the small menu that pops down under a node when you hover over it) shows click on the third little icon and drag it onto the page node you want a navigation screen on. Once I created all the screens I setup the navigation by opening up each screen and right clicking on the objects that needed to point to somewhere else in the prototype. Once I was done with the main page, my Home Navigation Page, it looked something like this in the Expression Blend Designer. I fleshed out each of the additional screens.  Once I was done I wanted to try out the deployment package.  The way to deploy a Sketchflow Prototype is to merely click on File –> Package SketchFlow Project and a prompt will appear.  In the prompt enter what you want the package to be called. I like to see the files generated afterwards too, so I checked the box to see that.  When Expression Blend is done generating everything you’ll have a directory like the one shown below, with all the needed files for deployment. Now these files can be copied or moved to any location for viewing.  One can even copy them (such as via FTP) to a server location to share with others.  Once they are deployed and you run the "TestPage.html" the other features of the Sketchflow Package are available. In the image below I have tagged a few sections to show the Sketchflow Player Features.  To the top left is the navigation, which provides a clearly defined area of movement in a list.  To the center right is the actual prototype application.  I have placed lists of things and made edits.  On the left hand side is the highlight feature, which is available in the Feedback section of the lower left.  On the right hand list I underlined the Autochart with an orange marker, and marked out two list items with a red marker. In the lower left hand side in the Feedback section is also an area to type in your feedback.  This can be useful for time based feedback, when you post this somewhere and want people to provide subsequent follow up feedback. Overall lots of great features, that enable some fairly rapid prototyping with customers.  Once one is familiar with the steps and parts of this Sketchflow Prototype Capabilities it is easy to step through an application without even stopping.  It really is that easy.  So get hold of Expression Blend 3 and get ramped up on Sketchflow, it will pay off in the design phases to do so!

  • International Radio Operators Alphabet in F# &amp; Silverlight &ndash; Part 2

    - by MarkPearl
    So the brunt of my my very complex F# code has been done. Now it’s just putting the Silverlight stuff in. The first thing I did was add a new project to my solution. I gave it a name and VS2010 did the rest of the magic in creating the .Web project etc. In this instance because I want to take the MVVM approach and make use of commanding I have decided to make the frontend a Silverlight4 project. I now need move my F# code into a proper Silverlight Library. Warning – when you create the Silverlight Library VS2010 will ask you whether you want it to be based on Silverlight3 or Silverlight4. I originally went for Silverlight4 only to discover when I tried to compile my solution that I was given an error… Error 12 F# runtime for Silverlight version v4.0 is not installed. Please go to http://go.microsoft.com/fwlink/?LinkId=177463 to download and install matching.. After asking around I discovered that the Silverlight4 F# runtime is not available yet. No problem, the suggestion was to change the F# Silverlight Library to a Silverlight3 project however when going to the properties of the project file – even though I changed it to Silverlight3, VS2010 did not like it and kept reverting it to a Silverlight4 project. After a few minutes of scratching my head I simply deleted Silverlight4 F# Library project and created a new F# Silverlight Library project in Silverlight3 and VS2010 was happy. Now that the project structure is set up, rest is fairly simple. You need to add the Silverlight Library as a reference to the C# Silverlight Front End. Then setup your views, since I was following the MVVM pattern I made a Views & ViewModel folder and set up the relevant View and ViewModels. The MainPageViewModel file looks as follows using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.Collections.ObjectModel; namespace IROAFrontEnd.ViewModels { public class MainPageViewModel : ViewModelBase { private string _iroaString; private string _inputCharacters; public string InputCharacters { get { return _inputCharacters; } set { if (_inputCharacters != value) { _inputCharacters = value; OnPropertyChanged("InputCharacters"); } } } public string IROAString { get { return _iroaString; } set { if (_iroaString != value) { _iroaString = value; OnPropertyChanged("IROAString"); } } } public ICommand MySpecialCommand { get { return new MyCommand(this); } } public class MyCommand : ICommand { readonly MainPageViewModel _myViewModel; public MyCommand(MainPageViewModel myViewModel) { _myViewModel = myViewModel; } public event EventHandler CanExecuteChanged; public bool CanExecute(object parameter) { return true; } public void Execute(object parameter) { var result = ModuleMain.ConvertCharsToStrings(_myViewModel.InputCharacters); var newString = ""; foreach (var Item in result) { newString += Item + " "; } _myViewModel.IROAString = newString.Trim(); } } } } One of the features I like in Silverlight4 is the new commanding. You will notice in my I have put the code under the command execute to reference to my F# module. At the moment this could be cleaned up even more, but will suffice for now.. public void Execute(object parameter) { var result = ModuleMain.ConvertCharsToStrings(_myViewModel.InputCharacters); var newString = ""; foreach (var Item in result) { newString += Item + " "; } _myViewModel.IROAString = newString.Trim(); } I then needed to set the view up. If we have a look at the MainPageView.xaml the xaml code will look like the following…. Nothing to fancy, but battleship grey for now… take careful note of the binding of the command in the button to MySpecialCommand which was created in the ViewModel. <UserControl x:Class="IROAFrontEnd.Views.MainPageView" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBox Grid.Row="0" Text="{Binding InputCharacters, Mode=TwoWay}"/> <Button Grid.Row="1" Command="{Binding MySpecialCommand}"> <TextBlock Text="Generate"/> </Button> <TextBlock Grid.Row="2" Text="{Binding IROAString}"/> </Grid> </UserControl> Finally in the App.xaml.cs file we need to set the View and link it to the ViewModel. private void Application_Startup(object sender, StartupEventArgs e) { var myView = new MainPageView(); var myViewModel = new MainPageViewModel(); myView.DataContext = myViewModel; this.RootVisual = myView; }   Once this is done – hey presto – it worked. I typed in some “Test Input” and clicked the generate button and the correct Radio Operators Alphabet was generated. And that’s the end of my first very basic F# Silverlight application.

  • Extending Blend for Visual Studio 2013

    - by Chris Skardon
    Originally posted on: http://geekswithblogs.net/cskardon/archive/2013/11/01/extending-blend-for-visual-studio-2013.aspxSo, I got a comment yesterday on my post about Extending Blend 4 and Blend for Visual Studio 2012 asking if I knew how to get it working for Blend for Visual Studio 2013.. My initial thoughts were, just change the location to get the blend dlls from Visual Studio 11.0 to 12.0 and you’re all set, so I went to do that, only to discover that the dlls I normally reference, well – they don’t exist. So… I’ve made a presumption that the actual process of using MEF etc is still the same. I was wrong. So, the route to discovery – required DotPeek and opening a few of blends dlls.. Browsing through the Blend install directory (./Microsoft Visual Studio 12.0/Blend/) I notice the .addin files: So I decide to peek into the SketchFlow dll, then promptly remember SketchFlow is quite a big thing, and hunting through there is not ideal, luckily there is another dll using an .addin file, ‘Microsoft.Expression.Importers.Host’, so we’ll go for that instead. We can see it’s still using the ‘IPackage’ formula, but where is that sucker? Well, we just press F12 on the ‘IPackage’ bit and DotPeek takes us there, with a very handy comment at the top: // Type: Microsoft.Expression.Framework.IPackage // Assembly: Microsoft.Expression.Framework, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a // MVID: E092EA54-4941-463C-BD74-283FD36478E2 // Assembly location: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Blend\Microsoft.Expression.Framework.dll Now we know where the IPackage interface is defined, so let’s just try writing a control. Last time I did a separate dll for the control, this time I’m not, but it still works if you want to do it that way. Let’s build a control! STEP 1 Create a new WPF application Naming doesn’t matter any more! I have gone with ‘Hello2013’ (see what I did there?) STEP 2 Delete: App.Config App.xaml MainWindow.xaml We won’t be needing them STEP 3 Change your application to be a Class Library instead. (You might also want to delete the ‘vshost’ stuff in your output directory now, as they only exist for hosting the WPF app, and just cause clutter) STEP 4 Add a reference to the ‘Microsoft.Expression.Framework.dll’ (which you can find in ‘C:\Program Files\Microsoft Visual Studio 12.0\Blend’ – that’s Program Files (x86) if you’re on an x64 machine!). STEP 5 Add a User Control, I’m going with ‘Hello2013Control’, and following from last time, it’s just a TextBlock in a Grid: <UserControl x:Class="Hello2013.Hello2013Control" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBlock>Hello Blend for VS 2013</TextBlock> </Grid> </UserControl> STEP 6 Add a class to load the package – I’ve called it – yes you guessed – Hello2013Package, which will look like this: namespace Hello2013 { using Microsoft.Expression.Framework; using Microsoft.Expression.Framework.UserInterface; public class Hello2013Package : IPackage { private Hello2013Control _hello2013Control; private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); Initialize(); } private void Initialize() { _hello2013Control = new Hello2013Control(); if (_windowService.PaletteRegistry["HelloPanel"] == null) _windowService.RegisterPalette("HelloPanel", _hello2013Control, "Hello Window"); } public void Unload(){} } } You might note that compared to the 2012 version we’re no longer [Exporting(typeof(IPackage))]. The file you create in STEP 7 covers this for us. STEP 7 Add a new file called: ‘<PROJECT_OUTPUT_NAME>.addin’ – in reality you can call it anything and it’ll still read it in just fine, it’s just nicer if it all matches up, so I have ‘Hello2013.addin’. Content wise, we need to have: <?xml version="1.0" encoding="utf-8"?> <AddIn AssemblyFile="Hello2013.dll" /> obviously, replacing ‘Hello2013.dll’ with whatever your dll is called. STEP 8 We set the ‘addin’ file to be copied to the output directory: STEP 9 Build! STEP 10 Go to your output directory (./bin/debug) and copy the 3 files (Hello2013.dll, Hello2013.pdb, Hello2013.addin) and then paste into the ‘Addins’ folder in your Blend directory (C:\Program Files\Microsoft Visual Studio 12.0\Blend\Addins) STEP 11 Start Blend for Visual Studio 2013 STEP 12 Go to the ‘Window’ menu and select ‘Hello Window’ STEP 13 Marvel at your new control! Feel free to email me / comment with any problems!

  • Silverlight Relay Commands

    - by George Evjen

Which I enjoy, since I like the idea of going into a day knowing that I am  going to learn something new. The issue that I am currently working on centers around relay commands. I have a pretty good handle on Relay Commands and how we use them within our applications. <Button Command="{Binding ButtonCommand}" CommandParameter="NewRecruit" Content="New Recruit" /> Here in our xaml we have a button. The button has a Command and a CommandParameter. The command binds to the ButtonCommand that we have in our ViewModel RelayCommand _buttonCommand;         /// <summary>         /// Gets the button command.         /// </summary>         /// <value>The button command.</value>         public RelayCommand ButtonCommand         {             get             {                 if (_buttonCommand == null)                 {                     _buttonCommand = new RelayCommand(                         x => x != null && x.ToString().Length > 0 && CheckCommandAvailable(x.ToString()),                         x => ExecuteCommand(x.ToString()));                 }                 return _buttonCommand;             }         }   In our relay command we then do some checks with a lambda expression. We check if the command  parameter is null, is the length greater than 0 and we have a CheckCommandAvailable method that will tell  us if the button is even enabled. After we check on these three items we then pass the command parameter to an action method. This is all pretty straight forward, the issue that we solved a few days ago centered around having a control that needed to use a Relay Command and this control was a nested control and was using a different DataContext. The example below illustrates how we handled this scenario. In our xaml usercontrol we had to set a name to this control. <Controls3:RadTileViewItem x:Class="RecruitStatusTileView"     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:Controls1="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"      xmlns:Controls2="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"      xmlns:Controls3="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"      mc:Ignorable="d" d:DesignHeight="400" d:DesignWidth="800" Header="{Binding Title,Mode=TwoWay}" MinimizedHeight="100"                             x:Name="StatusView"> Here we are using a telerik RadTileViewItem. We set the name of this control to “StatusView”. In our button control we set our command parameters and commands different than the example above. <HyperlinkButton Content="{Binding BigBoardButtonText, Mode=TwoWay}" CommandParameter="{Binding 'Position.PositionName'}" Command="{Binding ElementName=StatusView, Path=DataContext.BigBoardCommand, Mode=TwoWay}" /> This hyperlink button lives in a ListBox control and this listbox has an ItemSource of PositionSelectors. The Command Parameter is binding to the Position.Position property of that PositionSelectors object. This again is pretty straight forward again. What gets a bit tricky is the Command property in the hyperlink. It is binding to the element name we created in the user control (StatusView) Because this hyperlink is in a listbox and is in the item template it doesn’t have a direct handle on the DataContext that the RadTileViewItem has so we have to make sure it does. We do that by binding to the element name of status view then set the path to DataContext.BigBoardCommand. BigBoardCommand is the name of the RelayCommand in the view model. private RelayCommand _bigBoardCommand = null;         /// <summary>         /// Gets the big board command.         /// </summary>         /// <value>The big board command.</value>         public RelayCommand BigBoardCommand         {             get             {                 if (_bigBoardCommand == null)                 {                     _bigBoardCommand = new RelayCommand(x => true, x => AddToBigBoard(x.ToString()));                 }                 return _bigBoardCommand;             }         } From there we check for true again and then call the action and pass in the parameter that we had as the command parameter. What we are working on now is a bit trickier than this second example. In the above example we are only creating this TileViewItem with this name “StatusView” once. In another part of our application we are generating multiple TileViewItems, so we cannot set the name in the control as we cant have multiple controls with the same name. When we run the application we get an error that reads that the value is out of expected range. My searching has led me to think we cannot have multiple controls with the same name. This is today’s problem and Ill post the solution to this once it is found.

  • Extending Expression Blend 4 &amp; Blend for Visual Studio 2012

    - by Chris Skardon
    Just getting this off the bat, I presume this will also work for Blend 5, but I can’t confirm it… Anyhews, I imagine you’re here because you want to know how to create an addin for Blend, so let’s jump right in there! First, and foremost, we’re going to need to ensure our development environment has the right setup, so the checklist: Visual Studio 2012 Blend for Visual Studio 2012 OK, let’s create a new project (class library, .NET 4.5): Hello.Extension The ‘.Extension’ bit is very very important. The addin will not work unless it is named in this way. You can put whatever you want at the front, but it has to have the extension bit. OK, so now we have a solution with one project. To this project we need to add references to the following things: Microsoft.Expression.Extensibility (from c:\program files\Microsoft Visual Studio 11.0\Blend\   -- x86 folder if you are on an x64 windows install) Microsoft.Expression.Framework (same location as above) PresentationCore PresentationFramework WindowsBase System.ComponentModel.Composition Got them? ACE. Let’s now add a project to contain our control, so, create a new WPF Application project, cunningly named something like ‘Hello.Control’… (I’m creating a WPF application here, because I’m too lazy to dig up the correct references, and this will add all the ones I need ) Once that is created, delete the App.xaml and MainWindow.xaml files, we won’t be needing them. You will also need to change the properties of the project itself, so it is only a class library. Once that is done, let’s add a new UserControl, which will be this: <UserControl x:Class="Hello.Control.HelloControl" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBlock Text="HELLO!!!"/> </Grid> </UserControl> Impressive eh? Now, let’s reference the WPF project from the Extension library. All that’s left now is to code up our extension… So, add a class to the Extension project (name wise doesn’t matter), and make it implement the IPackage interface from the Microsoft.Expression.Extensibility library: public class HelloExtension : IPackage { /**/ } We’ll implement the two methods we need to: public class HelloExtension : IPackage { public void Load(IServices services) { } public void Unload() { } } We’re only really concerned about the Load method in this case, as let’s face it, the extension we have doesn’t need to do a lot to bog off. The interesting thing about the Load method is that it receives an IServices instance. This allows us to get access to all the services that Expression provides, in this case we’re interested in one in particular, the ‘IWindowService’ So, let’s get that bad boy… private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); } Nailed it… But why? The WindowService allows us to register our UserControl with Blend, which in turn allows people to activate and see it, which is a big plus point. So, let’s do that… We’ll create an ‘Initialize’ method to create our new control, and add it to the WindowService: private HelloControl _helloControl; public void Initialize() { _helloControl = new HelloControl(); if (_windowService.PaletteRegistry["HelloPanel"] == null) _windowService.RegisterPalette("HelloPanel", _helloControl, "Hello Window"); } First we check that we’re not already registered, and if we’re not we register, the first argument is the identifier used by the service to, well, identify your extension. The second argument is the actual control, the third argument is the name that people will see in the ‘Windows’ menu of Blend itself (so important note here – don’t put anything embarrassing or (need I say it?) sweary…) There are only two things to do now - Call ‘Initialize()’ from our Load method, and Export the class This is easy money – add [Export(typeof(IPackage))] to the top of our class… The full code will (should) look like this: [Export(typeof (IPackage))] public class HelloExtension : IPackage { private HelloControl _helloControl; private IWindowService _windowService; public void Load(IServices services) { _windowService = services.GetService<IWindowService>(); Initialize(); } public void Unload() { } public void Initialize() { _helloControl = new HelloControl(); if (_windowService.PaletteRegistry["HelloControl"] == null) _windowService.RegisterPalette("HelloControl", _helloControl, "Hello Window"); } } If you build this and copy it to your ‘Extensions’ folder in Blend (c:\program files\microsoft visual studio 11.0\blend\) and start Blend, you should see ‘Hello Window’ listed in the Window menu: That as they say is it!

  • File manager (Nautilus) hangs or is ultra slow when listing contents of ssh/sftp server

    - by NahsiN
    I used to use File -- Connect to server to connect to my remote ssh a lot before 12.04/11.10. But now in a fresh install of 12.04, whenever I try to access the remote files, nautilus either always hangs or is ultra slow (5 mins) in listing the directory contents. Most of the time I have to force quit or xkill. Mounting using SSHFS works fine. The ssh server is fast and it works fine via putty, mc (using fish) and normal terminal. I also installed nautilus in Lubuntu 12.04 (virtualbox) and to my surprise, browsing is fast and smooth. Both versions of nautilus are at 3.4.2 thus I am led to believe the problem might be lying somewhere in Ubuntu 12.04. But I am clueless. All suggestions welcome. I really need to solve this problem.

  • Part 4 of 4 : Tips/Tricks for Silverlight Developers.

    - by mbcrump
    Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #16) What is it? Find out version information about Silverlight and which WebKit it is using by going to http://issilverlightinstalled.com/scriptverify/. Why do I care? I’ve had those users that its just easier to give them a site and say copy/paste the line that says User Agent in order to troubleshoot a Silverlight problem. I’ve also been debugging my own Silverlight applications and needed an easy way to determine if the plugin is disabled or not. How do I do it: Simply navigate to http://issilverlightinstalled.com/scriptverify/ and hit the Verify button. An example screenshot is located below: Results from Chrome 7 Results from Internet Explorer 8 (With Silverlight Disabled) Tip/Trick #17) What is it? Use Lambdas whenever you can. Why do I care?  It is my personal opinion that code is easier to read using Lambdas after you get past the syntax. How do I do it: For example: You may write code like the following: void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted); } void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e) { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } } To me this style forces me to look for the other Method to see what the code is actually doing. The style located below is much easier to read in my opinion and does the exact same thing. void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += (s, e) => { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } }; } Tip/Trick #18) What is it? Prevent development Web Service references from breaking when Visual Studio auto generates a new port number. Why do I care?  We have all been there, we are developing a Silverlight Application and all of a sudden our development web services break. We check and find out that the local port number that Visual Studio assigned has changed and now we need up to update all of our service references. We need a way to stop this. How do I do it: This can actually be prevented with just a few mouse click. Right click on your web solution and goto properties. Click the tab that says, Web. You just need to click the radio button and specify a port number. Now you won’t be bothered with that anymore. Tip/Trick #19) What is it? You can disable the Close Button a ChildWindow. Why do I care?  I wouldn’t blog about it if I hadn’t seen it. Devs trying to override keystrokes to prevent users from closing a Child Window. How do I do it: A property exist on the ChildWindow called “HasCloseButton”, you simply change that to false and your close button is gone. You can delete the “Cancel” button and add some logic to the OK button if you want the user to respond before proceeding. Tip/Trick #20) What is it? Cleanup your XAML. Why do I care?  By removing unneeded namespaces, not naming all of your controls and getting rid of designer markup you can improve code quality and readability. How do I do it: (This is a 3 in one tip) Remove unused Designer markup: 1) Have you ever wondered what the following code snippet does? xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" This code is telling the designer to do something special with this page in “Design mode” Specifically the width and the height of the page. When its running in the browser it will not use this information and it is actually ignored by the XAML parser. In other words, if you don’t need it then delete it. 2) If you are not using a namespace then remove it. In the code sample below, I am using Resharper which will tell me the ones that I’m not using by the grayed out line below. If you don’t have resharper you can look in your XAML and manually remove the unneeded namespaces. 3) Don’t name an control unless you actually need to refer to it in procedural code. If you name a control you will take a slight performance hit that is totally unnecessary if its not being called. <TextBlock Height="23" Text="TextBlock" />   That is the end of the series. I hope that you enjoyed it and please check out Part 1 | Part 2 | Part 3 if your hungry for more.  Subscribe to my feed CodeProject

  • MySQL: "UPDATE command denied to user ''@'localhost'"

    - by Uncle Nerdicus
    For some reason when I installed MySQL on my machine (a Mac running OS X 10.9) the 'root' MySQL account got messed up and I don't have access to it, but I do have access to the standard MySQL account 'sean@localhost' which I use to log into phpMyAdmin. I am trying to reset the 'root' password by starting the mysqld daemon using the command mysqld --skip-grant-tables and then running the following lines in the mysql shell. mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') -> WHERE User='root'; mysql> FLUSH PRIVILEGES; Problem is when I try to run that MySQL string the daemon spits back a ERROR 1142 (42000): UPDATE command denied to user ''@'localhost' for table 'user' as if I didn't use the -u argument when I started the mysql shell, either though I did. Any help is muchly appreciated as I am lost at this point. :/

  • Where to obtain openssl-devel for SunOS 5.10

    - by user35949
    So I am having an issue that I have seen other people have on many different systems. I have to build Subversion on a SunOS 5.10 box and have run into issues. I have the openssl source code installed and in the subversion-1.6.9 folder, I run the following: ./configure --with-ssl --with-libs=/opt/exp/lib/openssl/lib and receive the error: checking for library containing RSA_new... not found configure: error: could not find library containing RSA_new configure failed for neon I have also tried running the command without the "lib" on the end of the --with-libs path. I read online that I need the openssl-devel packages, but I have been unable to find them for SunOS 5.10, and they do not show up already installed on my system when running pkginfo. I have looked online including http://www.sunfreeware.com/ which I was told was a good SunOS software source. Any help you can provide would be welcomed. Thanks, Sean

  • The Debut of Oracle Database Firewall at RSA 2011

    - by Troy Kitch
    We're very proud of the coverage and headlines Oracle Database Firewall made this past week during RSA Conference 2011 in San Francisco. In case you missed our previous post, we announced the availability of this latest addition to the Oracle Defense-in-Depth database security solutions. The announcement was picked up many publications including eWeek, CRN, InformationWeek and more. Here is just some of the press on this very important security solution: "It's rare to find a new product category these days, but I think a new product from Oracle fills the bill. In the crowded enterprise security field, that's saying something." Enterprise System Journal: A New Approach to Database Security By James E. Powell "Databases and the content they store are among the most valuable IT assets - and the most targeted by hackers. In an effort to help secure databases, Oracle today is launching the new Oracle Database Firewall as an approach to defend databases against SQL injection and other database attacks." Database Journal: Oracle Debuts Database Firewall (also appeared in InternetNews.com) By Sean Michael Kerner "Oracle Database Firewall understands SQL-statement formats, and can be configured to blacklist and whitelist traffic based on source. When it detects suspicious statements within SQL traffic -- ones that might indicate SQL injection attacks, for example -- it can replace them with neutral statements that will keep the session running without allowing potentially harmful traffic through." Network World: Oracle Database Firewall defuses SQL injection attacks By Tim Green "The firewall uses "SQL grammar analysis" to prevent SQL injection attacks and other attempts to grab information. The Oracle Database Firewall features white and black lists policies, exceptions and rules that mark the time of day, IP address, application and user." ZDNet: RSA Roundup: Oracle Database Firewall By Larry Dignan "The database giant announced Oracle Database Firewall on Feb. 14 at the RSA Conference in San Francisco. The firewall application establishes a "defensive perimeter" around databases by monitoring and enforcing normal application behavior in real-time, the company said." eWEEK: Oracle Database Firewall Delivers Vendor-Agnostic Security By Fahmida Y. Rashid
