Control Events- Revit API - revit-api

I would like to control events of Load Families and Create Type with revit api. Someone can give me a direction ? I don't understand very well the documentation that I read.

First you need to subscribe to an event by creating an event listener in the IExternalApplication OnStartup method.
public class AppCommand : IExternalApplication
{
public Result OnStartup(UIControlledApplication application)
{
application.ControlledApplication.FamilyLoadedIntoDocument += OnFamilyLoaded;
return Result.Succeeded;
}
}
Next you need a handler for that event:
private void OnFamilyLoaded(object sender, FamilyLoadedIntoDocumentEventArgs args)
{
// do work here
}
When finished you need to unregister the event handler:
public Result OnShutdown(UIControlledApplication application)
{
application.FamilyLoadedIntoDocument -= OnFamilyLoaded;
return Result.Succeeded;
}
The other events available that you can subscribe to are these:

Controlling the event ElementTypeDuplicated

I am controlling the event "application.ControlledApplication.ElementTypeDuplicated" and this event raise after the name of the new type is imputed, but after that I would like to override the result of the dialog box ( ID: "IDD_SYMBOL_ATTRIB") that were raised before the event ElementTypeDuplicated. I already try to get a Object Args and override the result inside the method that is suubscribing the event ElementTypeDuplicated, but is not working. Is there a way of doing this?
Example:
public void OnElementTypeDuplicated(object o, ElementTypeDuplicatedEventArgs args)
{
//doing things
duplicatingTypeArgs.OverrideResult(0);
}
}
}
public void OnDialogDuplicatingELement(object o, DialogBoxShowingEventArgs args)
{
if (args.DialogId=="IDD_SYMBOL_ATTRIB")
{
duplicatingTypeArgs = args;
}
}
Haven't tested this yet, but how about implementing IUpdater with "Element.GetChangeTypeElementAddition" instead subscribing to the duplicating type event
You could subscribe to the DocumentChanged event before duplicating the symbol. That will provide you with the element ids of all newly created elements. An example of using that is provided by the place family instance sample.
After the duplication, unsubscribe again.
You can use the Idling event to be notified when the duplication has terminated.

What's the alternative of onAfterLayout() of GXT2 in GXT3?

I migrate a project from GXT2 to GXT3. I can't find an alternative of the method onAfterLayout(). Any one have an idea please?
One option is to onAttach handler with a schedule deferred wrapped around a function should provide the behavior you want in the next event loop.
final GridWithRadiosWidget grid = new GridWithRadiosWidget();
grid.asWidget().addAttachHandler(new Handler() {
#Override
public void onAttachOrDetach(AttachEvent event) {
if (grid.asWidget().isAttached()) {
Scheduler.get().scheduleDeferred(new ScheduledCommand() {
#Override
public void execute() {
// Do something in the next event loop after it's rendered
}
});
}
}
});
And another option is to extend the layout container and extend onResize.

Background Task UWP - Pass Object with Data

I need to pass an object with some information to consume in my Background Task. I try to search in web but not found any solution. It is possible?
One workarround is save information what I need to pass in isolated storage in my MainProjet and in my BackgroundTask project consume information saved before. But this solution is not beautiful to use.
Someone help me?
Thanks in advance
You can use SendMessageToBackground method
var message = new ValueSet();
message.Add("key",value);
BackgroundMediaPlayer.SendMessageToBackground(message);
In background task listen to this method
public void Run(IBackgroundTaskInstance taskInstance)
{
BackgroundMediaPlayer.MessageReceivedFromForeground += BackgroundMediaPlayer_MessageReceivedFromForeground;
}
private void BackgroundMediaPlayer_MessageReceivedFromForeground(object sender, MediaPlayerDataReceivedEventArgs e)
{
foreach (string key in e.Data.Keys)
{
switch (key.ToLower())
{
}
}
}

Is it possible to exclude a url from Application Insights?

We have an Azure web role deployed that has been using Application Insights (ver. 1.0.0.4220), however, we're going over our data quota. Is it possible to configure Application Insights ignore a specific URL?
We have a status web service that gets a huge amount of traffic but never throws any errors. If I could exclude this one service URL I could cut my data usage in half.
Out of the box it is not supported. Sampling feature is coming but that would not be configurable by specific url. You can implement your own channel that would have your custom filtering. Basically your channel will get event to be sent, you check if you want to send it or not and then if yes pass to standard AI channel. Here you can read more about custom channels.
There are two things that changed since this blog post has been written:
channel should implement only ITelemetryChannel interface (ISupportConfiguration was removed)
and instead of PersistenceChannel you should use Microsoft.ApplicationInsights.Extensibility.Web.TelemetryChannel
UPDATE: Latest version has filtering support: https://azure.microsoft.com/en-us/blog/request-filtering-in-application-insights-with-telemetry-processor/
My team had a similiar situation where we needed to filter out urls that were successful image requests (we had a lot of these which made us hit the 30k datapoints/min limit).
We ended up using a modified version of the class in Sergey Kanzhelevs blog post to filter these out.
We created a RequestFilterChannel class which is an instance of ServerTelemetryChannel and extended the Send method. In this method we test each telemetry item to be sent to see if it is an image request and if so, we prevent it from being sent.
public class RequestFilterChannel : ITelemetryChannel, ITelemetryModule
{
private ServerTelemetryChannel channel;
public RequestFilterChannel()
{
this.channel = new ServerTelemetryChannel();
}
public void Initialize(TelemetryConfiguration configuration)
{
this.channel.Initialize(configuration);
}
public void Send(ITelemetry item)
{
if (item is RequestTelemetry)
{
var requestTelemetry = (RequestTelemetry) item;
if (requestTelemetry.Success && isImageRequest((RequestTelemetry) item))
{
// do nothing
}
else
{
this.channel.Send(item);
}
}
else
{
this.channel.Send(item);
}
}
public bool? DeveloperMode
{
get { return this.channel.DeveloperMode; }
set { this.channel.DeveloperMode = value; }
}
public string EndpointAddress
{
get { return this.channel.EndpointAddress; }
set { this.channel.EndpointAddress = value; }
}
public void Flush()
{
this.channel.Flush();
}
public void Dispose()
{
this.channel.Dispose();
}
private bool IsImageRequest(RequestTelemetry request)
{
if (request.Url.AbsolutePath.StartsWith("/image.axd"))
{
return true;
}
return false;
}
}
Once the class has been created you need to add it to your ApplicationInsights.config file.
Replace this line:
<TelemetryChannel Type="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel.ServerTelemetryChannel, Microsoft.AI.ServerTelemetryChannel"/>
with a link to your class:
<TelemetryChannel Type="XXX.RequestFilterChannel, XXX" />
Alternatively, you can disable the automated request collection and keep only exception auto-collection, just remove the RequestTrackingModule line from applicationinsights.config.
If you still need to collect some of the requests, not just filter all out, you can then call TrackRequest() (in the object of TelemetryClient class) from your code in the appropriate place after you know that you certainly need to log this request to AI.
Update: Filtering feature has been released some time ago and allows for exclusion of certain telemetry items way easier.

Silverlight - limit application to one WCF call at a time

Silverlight can only send a certain number of simultaneous WCF requests at a time. I am trying to serialize the requests that a particular section of my application is performing because I don't need them to run concurrently.
The problem is as follows (summary below):
"WCF proxies in Silverlight applications use the SynchronizationContext of the thread from which the web service call is initiated to schedule the invocation of the async event handler when the response is received. When the web service call is initiated from the UI thread of a Silverlight application, the async event handler code will also execute on the UI thread."
http://tomasz.janczuk.org/2009/08/improving-performance-of-concurrent-wcf.html
summary: basically, if you block the thread that is calling the async method, it will never get called.
I can't figure out the right model of threading this such which would give me what I want in a reasonable way.
My only other requirement is that I don't want the UI thread to block.
As far as I can see, what should work is if the UI thread has a worker thread which queues up the calls as Action delegates, then uses an AutoResetEvent to execute a task one at a time in yet another worker thread. There are two problems:
1) The thread that calls async can't block, because then async will never get called. In fact, if you put that thread into a wait loop, I've noticed it doesn't get called either
2) You need a way to signal from the completed method of the async call that it is done.
Sorry that was so long, thanks for reading. Any ideas?
I have used a class that i build on my own to execute load operations synchronous. With the class you can register multiple load operations of diffrent domaincontexts and then execute them one by one. You can provide an Action to the constructor of the class that gets called, when all operations are finished (successful or failed).
Here´s the code of the class. I think it´s not complete and you have to change it to match your expectations. Maybe it can help you in your situation.
public class DomainContextQueryLoader {
private List<LoadOperation> _failedOperations;
private Action<DomainContextQueryLoader> _completeAction;
private List<QueuedQuery> _pendingQueries = new List<QueuedQuery>();
public DomainContextQueryLoader(Action<DomainContextQueryLoader> completeAction) {
if (completeAction == null) {
throw new ArgumentNullException("completeAction", "completeAction is null.");
}
this._completeAction = completeAction;
}
/// <summary>
/// Expose the count of failed operations
/// </summary>
public int FailedOperationCount {
get {
if (_failedOperations == null) {
return 0;
}
return _failedOperations.Count;
}
}
/// <summary>
/// Expose an enumerator for all of the failed operations
/// </summary>
public IList<LoadOperation> FailedOperations {
get {
if (_failedOperations == null) {
_failedOperations = new List<LoadOperation>();
}
return _failedOperations;
}
}
public IEnumerable<QueuedQuery> QueuedQueries {
get {
return _pendingQueries;
}
}
public bool IsExecuting {
get;
private set;
}
public void EnqueueQuery<T>(DomainContext context, EntityQuery<T> query) where T : Entity {
if (IsExecuting) {
throw new InvalidOperationException("Query cannot be queued, cause execution of queries is in progress");
}
var loadBatch = new QueuedQuery() {
Callback = null,
Context = context,
Query = query,
LoadOption = LoadBehavior.KeepCurrent,
UserState = null
};
_pendingQueries.Add(loadBatch);
}
public void ExecuteQueries() {
if (IsExecuting) {
throw new InvalidOperationException("Executing of queries is in progress");
}
if (_pendingQueries.Count == 0) {
throw new InvalidOperationException("No queries are queued to execute");
}
IsExecuting = true;
var query = DequeueQuery();
ExecuteQuery(query);
}
private void ExecuteQuery(QueuedQuery query) {
System.Diagnostics.Debug.WriteLine("Load data {0}", query.Query.EntityType);
var loadOperation = query.Load();
loadOperation.Completed += new EventHandler(OnOperationCompleted);
}
private QueuedQuery DequeueQuery() {
var query = _pendingQueries[0];
_pendingQueries.RemoveAt(0);
return query;
}
private void OnOperationCompleted(object sender, EventArgs e) {
LoadOperation loadOperation = sender as LoadOperation;
loadOperation.Completed -= new EventHandler(OnOperationCompleted);
if (loadOperation.HasError) {
FailedOperations.Add(loadOperation);
}
if (_pendingQueries.Count > 0) {
var query = DequeueQuery();
ExecuteQuery(query);
}
else {
IsExecuting = false;
System.Diagnostics.Debug.WriteLine("All data loaded");
if (_completeAction != null) {
_completeAction(this);
_completeAction = null;
}
}
}
}
Update:
I´ve just noticed that you are not using WCF RIA Services, so maybe this class will not help your.
There are some options:
- You can take a look at the Agatha-rrsl either by inspecting the implementation of it or by just using it instead of pure wcf. The framework allows you to queue requests. You can read more here.
- Another option is to use the Reactive extension. There is a SO example here and more info here and here.
- You can try the Power Thread library from Jeffrey Richter. He describes it on his book CLR via C#. You can find the library here. This webcast gives you some info about it.
- You can always roll your own implementation. The yield statement is a good help here. Error handling makes it very difficult to get the solution right.
