  • Android - display specific contacts information

    - by Donal Rafferty
    In my application when a user clicks on a button I want to open the contacts application and display a particular contacts information. At the minute I have this: Intent intent = new Intent(Intent.ACTION_VIEW, People.CONTENT_URI); startActivity(intent); This displays the contact application with all the contacts displayed. But how do I get it to display just one contact according to the contacts name or number?

  • Import received e-mails from Outlook to MSSQL database

    - by _simon_
    How can I automatically import some data from received e-mail from Outlook to MSSQL database? So, when I receive an e-mail (from a preset sender), Outlook should be able to run an external application with the subject and body as parameter. This application will then parse the body of the e-mail and send it to database. Is it possible to set this in 'Rules and alerts' in Outlook (I don't think so)? Or is it possible to do it with macros (an example would be nice). Or else...? I am using Microsoft Outlook 2007 (no Exchange Server), let's say, that incoming mail is from @gmail domain, the externam application would probably be a C# console application, database is SQL SERVER 2005.

  • Unable to Sign in to the Microsoft Online Services Signin application from Windows 7 client located behind ISA firewall

    - by Ravindra Pamidi
    A while ago i helped a customer troubleshoot authentication problem with Microsoft Online Services Signin application.  This customer was evaluating Microsoft BPOS (Business Productivity Online Services) and was having trouble using the single sign on application behind ISA 2004 firewall.The network structure is fairly simple with single Windows 2003 Active Directory domain and Windows 7 clients. On a successful logon to the Microsoft Online Services Signin application, this application provides single signon functionality to all of Microsoft online services in the BPOS package. Symptoms:When trying to signin it fails with error "The service is currently unavailable. Please try again later. If problems continue, contact your service administrator". If ISA 2004 firewall is removed from the picture the authentication succeeds.Troubleshooting: Enabled ISA Server firewall logging along with Microsoft Network Monitor tool on the Windows 7 Client while reproducing the issue. Analysis of the ISA Server Firewall logs and Microsoft Network capture revealed that the Microsoft Online Services Sign In application when sending request to ISA Server does not send the domain credentials and as a result ISA Server responds with an error code of HTTP 407 Proxy authentication required listing out the supported authentication mechanisms.  The application in question is expected to send the credentials of the domain user in response to this request. However in this case, it fails to send the logged on user's domain credentials. Bit of researching on the Internet revealed that The "Microsoft Online Services Sign In" application by default does not support Outbound Internet Proxy authentication. In order for it to send the logged on user's domain credentials we had to make  changes to its configuration file "SignIn.exe.config" located under "Program Files\Microsoft Online Services\Sign In" folder. Step by Step details to configure the configuration file are documented on Microsoft TechNet website given below.  Configure your outbound authenticating proxy serverhttp://www.microsoft.com/online/help/en-us/helphowto/cc54100d-d149-45a9-8e96-f248ecb1b596.htm After the above problem was addressed we were still not able to use the "Microsoft Online Services Sign In" application and it failed with the same error.  Analysis of another network capture revealed that the application in question is now sending the required credentials and the connection seems to terminate at a later stage. Enabled verbose logging for the "Microsoft Online Services Sign In" application and then reproduced the problem. Analysis of the logs revealed a time difference between the local client and Microsoft Online services server of around seven minutes which is above the acceptable time skew of five minutes. Excerpt from Microsoft Online Services Sign In application verbose log:  1/26/2012 1:57:51 PM Verbose SingleSignOn.GetSSOGenericInterface SSO Interface URL: https://signinservice.apac.microsoftonline.com/ssoservice/UID1/26/2012 1:57:52 PM Exception SSOSignIn.SignIn The security timestamp is invalid because its creation time ('2012-01-26T08:34:52.767Z') is in the future. Current time is '2012-01-26T08:27:52.987Z' and allowed clock skew is '00:05:00'.1/26/2012 1:57:52 PM Exception SSOSignIn.SignIn  Although the Windows 7 Clients successfully synchronized time to the domain controller for the domain, the domain controller was not configured to synchronize time with external NTP servers. This caused a gradual drift in time on the network thus resulting in the above issue. Reconfigured the domain controller holding the PDC FSMO role to synchronize time with external time source ( time.nist.gov ) and edited the system policy on the ISA server firewall to allow NTP traffic to time.nist.gov Configure the time source for the forest:Windows Time Servicehttp://technet.microsoft.com/en-us/library/cc794937(WS.10).aspx Forced synchronization of Windows time using the command w32tm /resync on the domain controller and later on the clients each of which had corrected the seven minutes difference. This resolved the problem with logon to Microsoft Online Services Sign In.

  • InvalidOperationException: The Undo operation encountered a context that is different from what was

    - by McN
    I got the following exception: Exception Type: System.InvalidOperationException Exception Message: The Undo operation encountered a context that is different from what was applied in the corresponding Set operation. The possible cause is that a context was Set on the thread and not reverted(undone). Exception Stack: at System.Threading.SynchronizationContextSwitcher.Undo() at System.Threading.ExecutionContextSwitcher.Undo() at System.Threading.ExecutionContext.runFinallyCode(Object userData, Boolean exceptionThrown) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteBackoutCodeHelper(Object backoutCode, Object userData, Boolean exceptionThrown) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Net.ContextAwareResult.Complete(IntPtr userToken) at System.Net.LazyAsyncResult.ProtectedInvokeCallback(Object result, IntPtr userToken) at System.Net.Sockets.BaseOverlappedAsyncResult.CompletionPortCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* nativeOverlapped) at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP) Exception Source: mscorlib Exception TargetSite.Name: Undo Exception HelpLink: The application is a Visual Studio 2005 (.Net 2.0) console application. It is a server for multiple TCP/IP connections, doing asynchronous socket reads and synchronous socket writes. In searching for an answer I came across this post which talks about a call to Application.Doevents() which I don't use in my code. I also found this post which has a resolution involved with Component which I also don't use in my code. The application does reference a library that I created that contains custom user controls and components, but they are not being used by the application. Question: What caused this to happen and how do I prevent this from happening again? Or a more realistic question: What does this exception actually mean? How is "context" defined in this situation? Anything that can help me understand what is going on would be very much appreciated.

  • Creating Ruby applications for Windows.

    - by Omega
    I want to develop a Windows application. Honestly I care little about cross-platforms for now (but still would be good) I want to use Ruby, since it has quite a simple syntax and is so.. well, simple and easy to learn. My application is like a "game level creator", where you can design your own level and then run it with another application which is a "game level player" by reading the project file created by the creator app. You get the idea. Now, I got a new PC and is completely clean. Absolutely no trace of my old Ruby experiments and fails. First of all, I will need to choose a GUI platform for my Ruby application! Can you recommend me one? I have heard of Shoes and Tk, but want to know what you think.

  • Calling a WPF Appliaction and modify exposed properties?

    - by Justin
    I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to. Right now I have a file *.Keys.Set which tells the appliaction (on open) to style itself according to that new style. I know this file could be passed as a command line argument into the appliaction. That would not be a problem. My concern is, is thier a way via a managed environment to change the properties of the executable as long as they are exposed properly, an example: 'Creates a new instance of the Keyboard Appliaction Dim e_key as new WpfAppliaction("C:\egt\components\keyboard.exe") 'Sets the style path e_key.SetStylePath("c:\users\joe\apps\me\default.keys.set") e_key.Refresh() 'Applies the style e_key.HideMenu() 'Hides the menu e_key.ShowDeck("PIN") 'Shows the custom "deck" of keyboard keys the developer 'Created in the style appliaction. ''work with events and resposne 'Clear the instance from memory e_key.close e_key.dispose e_key = nothing This would allow my application to become easily accessible to other Touch Screen Application Developers, allowing them to use my key_board and keep the functionality they need. It seems like it might be possible because (name of executable).application shows all the exposed functions, properties, and values. I just have never done this before. Any help would be appreciated, thank you in advance.

  • Converting a Matrix to a grid of colors

    - by Zach
    I'm currently making a console application in C# (will be going to a Windows Form application in the future. Sooner if needed). My current objective is to have a matrix (current size 52x42) be exported as an image (bitmap, jpeg, png, I'm flexible) where each value in the matrix (0, 1, 2, 3) is portrayed as a white, black, blue, or red square of size 20px x 20px with a grid 1px wide seperating each 'cell'. Can this even be done in a console application, and if so how? If not, what would I need to get it working in a Windows Form application?

  • How to Use a Windows App with Embeded files and folders to copy to a destination. In C#

    - by Mark Sweetman
    I am trying to write a small application, whose only purpose is to copy some folders and .cs source files into a user specified Directory, I can do it easy enough by simply having the application look for the files and folders in its own install directory then copy them to thier destination Directory, but I was wondering if its possible to Embed the Folders and Files into the Application, so that when you run the application it creates or copies the folders and files from the exe app directly to the install directory, rather than searching for them in the apps install directory then copying them over. Basically Im trying to only have a single exe file rather than having an exe file and a bunch of folders and files along side it. Is this possible to do with just a Windows Form App without using an actual Installer Class?

  • Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

    Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core.  Made for an easy cut-and-paste operation with a few items being switched from one to another.  Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview?  Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar.  The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM.  We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase.  This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this.  Then you can add-on functionality as needed.  Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03.    private int _applicantID; 04.    public int ApplicantID 05.    { 06.        get { return this._applicantID; } 07.        set 08.        { 09.            if (_applicantID != value) 10.            { 11.                _applicantID = value; 12.                OnPropertyChanged("ApplicantID"); 13.            } 14.        } 15.    } 16.   17.    private int _postingID; 18.    public int PostingID 19.    { 20.        get { return _postingID; } 21.        set 22.        { 23.            if (_postingID != value) 24.            { 25.                _postingID = value; 26.                OnPropertyChanged("PostingID"); 27.            } 28.        } 29.    } 30.   31.    private string _body; 32.    public string Body 33.    { 34.        get { return _body; } 35.        set 36.        { 37.            if (_body != value) 38.            { 39.                _body = value; 40.                OnPropertyChanged("Body"); 41.            } 42.        } 43.    } 44.   45.    private int _interviewID; 46.    public int InterviewID 47.    { 48.        get { return _interviewID; } 49.        set 50.        { 51.            if (_interviewID != value) 52.            { 53.                _interviewID = value; 54.                OnPropertyChanged("InterviewID"); 55.            } 56.        } 57.    } 58.   59.    public override IAppointment Copy() 60.    { 61.        IAppointment appointment = new InterviewAppointment(); 62.        appointment.CopyFrom(this);             63.        return appointment; 64.    } 65.   66.    public override void CopyFrom(IAppointment other) 67.    {             68.        base.CopyFrom(other); 69.        var appointment = other as InterviewAppointment; 70.        if (appointment != null) 71.        { 72.            ApplicantID = appointment.ApplicantID; 73.            PostingID = appointment.PostingID; 74.            Body = appointment.Body; 75.            InterviewID = appointment.InterviewID; 76.        } 77.    } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc.  But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is.  The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased.  For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control.  I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog.  Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.    <!-- begin Necessary Windows 7 Theme Resources for

template. Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting.  The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection.  You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  AppointmentsSource="{Binding Interviews}" 09.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 10.                  command:AppointmentAddedEventClass.Command="{Binding AddAppointmentCommand}" 11.                  command:ApptCreatedEventClass.Command="{Binding ApptCreatingCommand}" 12.                  command:ApptEditedEventClass.Command="{Binding ApptEditedCommand}" 13.                  command:ApptDeletedEventClass.Command="{Binding ApptDeletedCommand}"> 14.</telerikScheduler:RadScheduler> Now, we get to the ViewModel and what it takes to get that rigged up.  And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events.  This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.  Of course, feel free to ask me questions about anything that isn't clear (by line number, ideally) so I can help out if I have missed anything important: 001.public class SchedulerViewModel : ViewModelBase 002.{ 003.    private readonly IEventAggregator eventAggregator;

4.    base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments.  End result?  I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm.  I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version.  For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09.                  AppointmentAdded="xJobsScheduler_AppointmentAdded" 10.                  AppointmentCreating="xJobsScheduler_AppointmentCreating" 11.                  AppointmentEdited="xJobsScheduler_AppointmentEdited" 12.                  AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right?  Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate.  The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event.  Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003.    public RecruitingContext context;

So what have we learned here today?  One, for the most part this MVVM thing is somewhat easy.  Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow.  Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4.  Brilliant!  MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development.  Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view.  Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

    Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core.  Made for an easy cut-and-paste operation with a few items being switched from one to another.  Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview?  Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar.  The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM.  We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase.  This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this.  Then you can add-on functionality as needed.  Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03.    private int _applicantID; 04.    public int ApplicantID 05.    { 06.        get { return this._applicantID; } 07.        set 08.        { 09.            if (_applicantID != value) 10.            { 11.                _applicantID = value; 12.                OnPropertyChanged("ApplicantID"); 13.            } 14.        } 15.    } 16.   17.    private int _postingID; 18.    public int PostingID 19.    { 20.        get { return _postingID; } 21.        set 22.        { 23.            if (_postingID != value) 24.            { 25.                _postingID = value; 26.                OnPropertyChanged("PostingID"); 27.            } 28.        } 29.    } 30.   31.    private string _body; 32.    public string Body 33.    { 34.        get { return _body; } 35.        set 36.        { 37.            if (_body != value) 38.            { 39.                _body = value; 40.                OnPropertyChanged("Body"); 41.            } 42.        } 43.    } 44.   45.    private int _interviewID; 46.    public int InterviewID 47.    { 48.        get { return _interviewID; } 49.        set 50.        { 51.            if (_interviewID != value) 52.            { 53.                _interviewID = value; 54.                OnPropertyChanged("InterviewID"); 55.            } 56.        } 57.    } 58.   59.    public override IAppointment Copy() 60.    { 61.        IAppointment appointment = new InterviewAppointment(); 62.        appointment.CopyFrom(this);             63.        return appointment; 64.    } 65.   66.    public override void CopyFrom(IAppointment other) 67.    {             68.        base.CopyFrom(other); 69.        var appointment = other as InterviewAppointment; 70.        if (appointment != null) 71.        { 72.            ApplicantID = appointment.ApplicantID; 73.            PostingID = appointment.PostingID; 74.            Body = appointment.Body; 75.            InterviewID = appointment.InterviewID; 76.        } 77.    } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc.  But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is.  The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased.  For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control.  I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog.  Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.    <!-- begin Necessary Windows 7 Theme Resources for

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting.  The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection.  You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  AppointmentsSource="{Binding Interviews}" 09.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 10.                  command:AppointmentAddedEventClass.Command="{Binding AddAppointmentCommand}" 11.                  command:ApptCreatedEventClass.Command="{Binding ApptCreatingCommand}" 12.                  command:ApptEditedEventClass.Command="{Binding ApptEditedCommand}" 13.                  command:ApptDeletedEventClass.Command="{Binding ApptDeletedCommand}"> 14.</telerikScheduler:RadScheduler> Now, we get to the ViewModel and what it takes to get that rigged up.  And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events.  This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.  Of course, feel free to ask me questions about anything that isn't clear (by line number, ideally) so I can help out if I have missed anything important: 001.public class SchedulerViewModel : ViewModelBase 002.{ 003.    private readonly IEventAggregator eventAggregator;

4.    base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments.  End result?  I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm.  I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version.  For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.                  Grid.Row="1" 03.                  Grid.Column="1" 04.                  Width="800" 05.                  MinWidth="600" 06.                  Height="500" 07.                  MinHeight="300" 08.                  EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09.                  AppointmentAdded="xJobsScheduler_AppointmentAdded" 10.                  AppointmentCreating="xJobsScheduler_AppointmentCreating" 11.                  AppointmentEdited="xJobsScheduler_AppointmentEdited" 12.                  AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right?  Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate.  The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event.  Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003.    public RecruitingContext context;

So what have we learned here today?  One, for the most part this MVVM thing is somewhat easy.  Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow.  Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4.  Brilliant!  MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development.  Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view.  Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Windows Server 2008 / SQL 2008 Licensing for Authenticated Web Application

    - by MikeM
    Hello, I'm trying to crunch some numbers to see what the software costs involved are for hosting an application we are developing. Users will not be anonymous - they will need to log in. SQL Server 2008: SQL Server licensing is easy - it will be licensed per-processor. No real fuss there. The cost of CALs would be much higher for the number of users as compared to the processor licenses. Windows Server 2008: This is where it gets trickier. We need to license the OS for both the web servers (there will be a couple) plus the database servers (also a couple). The Web Servers could run on the Web Edition without a need for CALs, but if you continue reading, you will see that may not matter much because I will likely have user CALs for each user anyway. We can't use the "External Connector" for any of the Windows licenses, because that doesn't cover customers who are paying to access a hosted application. We can't use the Web Edition for the SQL Servers because that license only allows database running on Web Edition to host data for the local web application (i.e. other web servers can't connect to it). So that leaves us with the "full" editions of Windows Server for the database server OS. I find this a little rediculous, and I feel as though I must be missing something, but it looks to me like I will actually need to buy a CAL for every user who signs up to use our service. I feel like I'm missing something because that means that for every user, I have to shell out $40 for a CAL. That could be one or two years' worth of revenue from each user for an inexpensive service! Is there any way to serve a web application to authenticated users without paying for individual Windows Server CALs, if the web servers and SQL servers are seperate boxes?

  • Legacy non-dpi-aware application resolution scaling?

    - by Miles Erickson
    Our environment prominently featuers an outdated but absolutely mission-critical Win32 application that is not dpi-aware. It is optimized for an 800x600 display. Most of our users now have 17"-20" displays with native resolutions ranging from 1280x1024 to 1680x1050. However, they still operate these displays at 800x600 because the text in this legacy application is otherwise too small. Of course, it also means that nothing quite fits on the screen in Office 2007. Most of our workstations still run Windows XP, but some are on Windows 7 and there are more to come. About one-third of our users run the app remotely via MS Terminal Services, and the remainder run it locally. Is anyone aware of any method that could be used to scale this specific application to about 170%, so that it would fill a 1280x1024 screen, without affecting other applications that work best at the display's native resolution? I know how to do this in Mac OS X, but I have never found a way to do it in Windows. Of course, this ideally would be something that we could push out via Group Policy. I suppose we even could create a custom MSI package to re-deploy the legacy application with some sort of display virtualization layer, if such a thing exists.

  • help Add Any Application Shortcut in Desktop Context Menu

    - by blackjack
    i got the info here but after adding that i didn't get any shortcut on my desktop contest menu :( pls help me i want it only on my desktop context menu Open regedit and goto: CODEHKEY_CLASSES_ROOT\Directory\Background\shell now under this key create another key with any name and in right-side pane set its value to the label, which you want to show in desktop context menu, like Media Player, Winamp, Firefox, anything else. Now create another key under this newly created key with name command. and in right-side pane set its value to the exact path of application, like: C:\Program Files\Windows Media Player\wmplayer.exe C:\Program Files\Winamp\winamp.exe etc... Thats it. Now you can check your favorite application shortcut in desktop context menu. You can create as many shortcut as you want. Simply create a separate key for all the applications. Following is a ready-made code: CODEWindows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP] @="Windows Media Player" [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP\command] @="C:\Program Files\Windows Media Player\wmplayer.exe" Just change the label and path to ur desired application and save with the name "vishal.reg" (including the quotes) and run it. U can also set the application shortcut to show only when u press key by adding "Extended" String value in right-side pane of the newly created key: CODEWindows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP] @="Windows Media Player" "Extended"="" [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP\command] @="C:\Program Files\Windows Media Player\wmplayer.exe"

  • SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified data

    - by eulerfx
    I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.

  • Our application is responding different on client server

    - by WtFudgE
    I have an application running on our local server and it works perfect. However when I deploy my application to our client's server there are problems. If i copy all the sources to another local from their server, it works fine again.... I am talking about an ASP.NET application talking with windows server 2008. The server specs of our client are: intel Xeon 2.13 GHz 6 GB RAM 300 GB HDD windows server 2008 R2 Although I think it's not that important I will describe the problems I am talking about to give u a better idea: It is related to upating and deleting fields in the sql server. Whenever there is more than one user running the application, and updates or deletes (not even the same record!0, there seems to be fields updating/deleting wrongly. But as I said before, if we copy the source to another server it is not the case. So I assumed it is more configuration related. Do you guys have any idea what the issue could be? Thanks a lot EDIT: my client old me he disabled the sql related accounts Could this be related?

  • What is optimal hardware configuration for heavy load LAMP application

    - by Piotr K.
    I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).
