Is there a way to customize/edit the default template of the event handling methods in Visual Studios 2008/2010 such that upon creation, the event handler already has a try/catch block in it?
the default behavior is
private void button1_Click(object sender, EventArgs e)
{
}
I'd like to be able to set the development environment to do
private void button1_Click(object sender, EventArgs e)
{
try
{
///TODO: Add logic here
}
catch
{
throw;
}
finally
{
}
}
I've already edited the templates located in the ItemTemplates folder so that they meet the coding standard where I work, but I'd also like to edit the method templates if possible. I've searched the 'Net for the better part of a week and found nothing. Any assistance would be greatly appreciated.

Have you considered Editing Event method stub in the Code Snippet manager or adding a new snippet?

I am trying to configure my installer so that it will close any instances of the application before installation starts and relaunch the application once installation has finished.
The MS documents provide and example similar to the one below and indicate that the [RunInstaller(true)] annotation specifies whether the Visual Studio Custom Action Installer or the Installutil.exe (Installer Tool) should be invoked when the assembly is installed.
Of course this could mean just about anything...
I am using the Visual Studio Project Installer NuGet package to create the install files (setup.exe and APP.msi files). When configuring the Project Installer there is an option set configure the Custom Actions - I assume this is what the documentation means.
However the Custom Actions has options to add things to the Install, Commit sections - what has to be added to these sections and how does this relate to the Installer class defined below.
This whole area of installation seems to be poorly documented and there seem to be so many options, none of which seem to work properly.
You would think closing any running instances before installing an update and then relaunching after completing the installation would be a no brainer but it seems anything but simple.
Appreciate any assistance with a working example of how this can be achieved.
namespace FocusBracketer
{
[RunInstaller(true)]
public partial class Installer: System.Configuration.Install.Installer
{
public Installer() : base()
{
InitializeComponent();
// Attach the 'BeforeInstall' event.
this.BeforeInstall += new InstallEventHandler(Installer_BeforeInstall);
// Attach the 'Committed' event.
this.Committed += new InstallEventHandler(Installer_Committed);
// Attach the 'Committing' event.
this.Committing += new InstallEventHandler(Installer_Committing);
}
// Event handler for 'BeforeInstall' event.
private void Installer_BeforeInstall(object sender, InstallEventArgs e)
{
Console.WriteLine("");
Console.WriteLine("BeforeInstall Event occurred.");
Console.WriteLine("");
}
// Event handler for 'AfterInstall' event.
private void Installer_AfterInstall(object sender, InstallEventArgs e)
{
Console.WriteLine("");
Console.WriteLine("AfterInstall Event occurred.");
Console.WriteLine("");
System.Diagnostics.Process.Start(System.IO.Path.GetDirectoryName(this.Context.Parameters["AssemblyPath"]) + #"\FocusBracketer.exe");
}
// Event handler for 'Committing' event.
private void Installer_Committing(object sender, InstallEventArgs e)
{
Console.WriteLine("");
Console.WriteLine("Committing Event occurred.");
Console.WriteLine("");
}
// Event handler for 'Committed' event.
private void Installer_Committed(object sender, InstallEventArgs e)
{
Console.WriteLine("");
Console.WriteLine("Committed Event occurred.");
Console.WriteLine("");
}
// Override the 'Install' method.
public override void Install(IDictionary savedState)
{
base.Install(savedState);
}
// Override the 'Commit' method.
public override void Commit(IDictionary savedState)
{
base.Commit(savedState);
}
// Override the 'Rollback' method.
public override void Rollback(IDictionary savedState)
{
base.Rollback(savedState);
}
public static void Main()
{
Console.WriteLine("Usage : installutil.exe Installer.exe ");
}
}
}
I have these code, according to document from sitefinity:
protected void Application_Start(object sender, EventArgs e)
{
Bootstrapper.Initialized += new EventHandler<ExecutedEventArgs>(Bootstrapper_Initialized);
}
public void Bootstrapper_Initialized(object sender, ExecutedEventArgs args)
{
if (args.CommandName == "Bootstrapped")
{
EventHub.Subscribe<ICommentEvent>(evt => CommentsEvent.CommentEventHandler(evt));
}
}
And the handler:
public static void CommentEventHandler(ICommentEvent evt)
{
// My code here
}
The problem is this handler always runs twice when a comment event happens (post a comment or approve a comment).
Could you please tell me why this happens and any possible way to avoid this? (I don't believe static boolean is a good idea).
Thanks
ICommentEvent is a base interface that is implemented by multiple events such as ICommentCreatingEvent, ICommentCreatedEvent, ICommentUpdatingEvent, ICommentUpdatedEvent and some others.
In your case it is fired twice due to firing of both ICommentCreatingEvent and ICommentCreatedEvent.
You can subscribe to just one of them and it should fire just once.
I am trying to get a function to be called everytime an event occurs. In the KinectRegion class there is an event called HandPointerGrip: http://msdn.microsoft.com/en-us/library/microsoft.kinect.toolkit.controls.kinectregion.handpointergrip.aspx.
I see that it has declared the event and it seems to me that the event has already been set to be invoked(HandPointerEventArgs)? How do I attach a function to this event?
public Menu()
{
KinectRegion.HandPointerGripEvent+=Hand_Gripped; // why doesn't this work? :(
}
private void Hand_Gripped(object sender, HandPointerEvnetArgs e)
{
MessageBox.Show("I work!"); // I wish this would work
}
Been working hard on this problem and here is something I think will work. Afraid to test it. Learning a lot about routed events, delegates, and events.
namespace ...
{
public delegate void HandPointerEventHandler(object sender, HandPointerEventArgs e);
public partial class thePage : Page
{
public event HandPointerEventHandler HandGripped
{
add {this.AddHandler(KinectRegion.HandPointerGripEvent,value);}
remove {this.RemoveHandler(KinectRegion.HandPointerGripEvent,vlaue);}
}
public thePage()
{
InitializeComponent();
this.HandGripped += new HandPointerEventHandler(OnHandGripped);
}
protected virtual void OnHandGripped(object sender, HandPointerEventArgs e)
{
MessageBox.Show("hello"); //hopefully
}
}
}
The first block of code should work fine. My guess is that the HandPointerGripEvent is hooked up ok, it just never fires.
How are you setting up your KinectRegion?
Are you updating the interration library each frame?
Perhaps this helps?
Kinect SDK 1.7: Mapping Joint/Cursor Coordinates to screen Resolution
KinectRegion.AddHandPointerGripHandler(this.Button1, this.Button1_Click);
Here Button1 is:
< k:KinectTileButton x:Name="Button1" Height="150" Width="150" Content="Click"/ >
The namespaces:
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:k="http://schemas.microsoft.com/kinect/2013"
Button1_Click is the method itself, for example:
private void Button1_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("YOU GOT ME !!!");
}
If you want to add a grip handler for another interface object, you just do:
KinectRegion.AddHandPointerGripHandler(< object name >, < method name >);
And s.o.
I have a problem with two of my EventHandlers, they work the same, so here is one:
private void Form1_Load(object sender, EventArgs e)
{
webBrowserWebsite.Url = new System.Uri(textBoxURL.Text, System.UriKind.Absolute);
webBrowserWebsite.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowserWebsite_DocumentCompleted);
}
void webBrowserWebsite_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
StreamWriter(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\CurrentData.wfd");
sw.Write(webBrowserWebsite.Document.Body.InnerText);
sw.Close();
}
The problem is, that the EventHandler fires multiple times, it doesn't stop!
Why is it doing this?
Thanks in advance
The code that you have written won't compile (your StreamWriter in your EventHandler isn't assigned to anything) and without more context as to how you are calling this, it is difficult to say for certain.
But the most likely reason is you are calling Form1_Load multiple times, but using the same webBrowserWebsite object. Each time the form loads, you are adding a new Event Handler. And since you aren't showing any code showing where you removing the event handler, I'm guessing it fires once for each time you call Form_Load.
Depending on your design, you are better off adding the event handler in the constructor so it is only added once regardless of the number of times you load the form.
public Form1()
{
webBrowserWebsite.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowserWebsite_DocumentCompleted);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowserWebsite.Url = new System.Uri(textBoxURL.Text, System.UriKind.Absolute);
}
Or remove the event handler in the event handler:
void webBrowserWebsite_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
StreamWriter(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\CurrentData.wfd");
sw.Write(webBrowserWebsite.Document.Body.InnerText);
sw.Close();
webBrowserWebsite.DocumentCompleted -= webBrowserWebsite_DocumentCompleted;
}
Also, since StreamWriter implements IDisposible, you should be putting it inside of a using block or at least calling sw.Dispose() at the end of the method
Are there any exception logging components in Windows Phone applications? Do you have any suggestions about logging records in Windows Phone applications?
For logging to Visual Studio while running, you can use Debug.Write.
As far as logging exceptions to a file, WP7Contrib has an exception logging library that is available as part of WP7Contrib.Core on NuGet. WP7Contrib.Core's only dependencies are the Rx libraries.
Edit: You can use the WP7Contrib logging library like this:
private ILogManager logManager = new LoggingService();
private void Application_Launching(object sender, LaunchingEventArgs e)
{
logManager.Enable();
}
private void Application_Activated(object sender, ActivatedEventArgs e)
{
logManager.Enable();
}
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
logManager.Disable();
}
private void Application_Closing(object sender, ClosingEventArgs e)
{
logManager.Disable();
}
Edit 2:
Having said that, I'd probably just use an extention method:
// App.xaml.cs
private ILogManager logManager = new LoggingService();
public App()
{
logManager.Attach(PhoneApplicationService.Current);
}
// LogManagerExtensions.cs
public static class LogManagerExtensions
{
public static void Attach(this ILogManager logManager, PhoneApplicationService appService)
{
appService.Launching += (s,e) => logManager.Enable();
appService.Activated += (s,e) => logManager.Enable();
appService.Deactivated += (s,e) => logManager.Disable();
appService.Closing += (s,e) => logManager.Disable();
}
}
NLog is quite good

I saw Telerik are talking about releasing RadDiagnostics soon. I'm planning to get a look at it in the next app I release. Details from http://blogs.telerik.com/blogs/posts/12-02-01/introducing-raddiagnostics-for-windows-phone.aspx
well.you can try WP7Contrib OpenSource Project At CodePlex[http://wp7contrib.codeplex.com/] and get Exception Log Record in the Windows phone Application.
if you did't want to use opensource Project 。 you can define Component by yourself. Store Exception record as file in Isolated Storage。
