I am trying to manipulate Style Sheets through:
GeckoFXWebBrowser.Document.StyleSheets
as mentioned here, but clearing or adding any rules as mentioned there throwing exceptions related to JSContext, also I tried to use nsIStyleSheetService similarly to what mentioned here as follows:
Dim SSS = Gecko.Xpcom.CreateInstance(Of Gecko.nsIStyleSheetService)("#mozilla.org/content/style-sheet-service;1")
Dim mUri = Gecko.IOService.CreateNsIUri("myCSSUri")
SSS.LoadAndRegisterSheet(mUri, Gecko.nsIDOMWindowUtilsConsts.USER_SHEET)
But this also throwing ambigious COM related exception.
I tried all this in DocumentCompleted event.
Any ideas what is wrong here? or how to accomplish task? (GeckoFX 29)
Since the FAQ entry was written Firefox has had some security changes which is prolly the cause of the initial exceptions.
Check out the Geckofx 29 unittests here in particular :
[Test]
public void GetCssRules_DoesNotThrowException()
{
GeckoStyleSheet styleSheet = _browser.Document.StyleSheets.First();
GeckoStyleSheet.StyleRuleCollection cssRules = null;
Assert.DoesNotThrow(() => { cssRules = styleSheet.CssRules; });
Assert.DoesNotThrow(() => { cssRules.Insert(0, "#blanc { color: white }"); });
Assert.DoesNotThrow(() => { cssRules.RemoveAt(0); });
Assert.DoesNotThrow(() => { cssRules.Clear(); });
}
As for the second method using nsIStyleSheetService:
Dim mUri = Gecko.IOService.CreateNsIUri("myCSSUri")
Is likely to work better if you specify a valid uri. (eg. http://www.google.com)

I'm trying to convert the JavaScript code
if (window.ifEdit.editIsDirty()) { }
into Typescript. I got as far as the following
var iframe = document.getElementById('ifEdit');
var iWindow = <HTMLIFrameElement>(iframe).contentWindow;
var _editIsDirty = iWindow.editIsDirty();
I get the red squiggles under 'contentWindow' and 'editIsDirty' saying the method/property does not exist on the type. The .ts doesn't compile to a .js file.
I have searched, but did not manage to find a solution.
For the contentWindow part, the problem with your code is that the casting is done wrong, should be:
var iWindow = (<HTMLIFrameElement> iframe).contentWindow;
As for the editIsDirty, it's not a standard property of Window.
If it's something which is added in the environment in which you are running your javascript then you need to declare it like so:
interface IfEdit {
editIsDirty(): boolean;
}
interface Window {
ifEdit: IfEdit;
}
var iframe = document.getElementById("ifEdit");
var iWindow = (<HTMLIFrameElement> iframe).contentWindow;
var _editIsDirty = iWindow.ifEdit.editIsDirty();
Use the code in Playground.
Casting will be through as. this assures .contentWindow is accessible.
const iframe = document.getElementById('embed-player') as HTMLIFrameElement;
if (!iframe) {
// Handle case where iframe not found
return;
}
const contentWindow = iframe.contentWindow;
// Note: You will likely need more null handling for contentWindow's properties
console.log(contentWindow?.document);
I receive the following error when I try to run my code. I haven't managed to solve it yet, please Help:
edit: Marked with * where it fails.
>
public IQueryable<Video> GetVideos([QueryString("id")] int? categorieId)
{
var _db = new TeleviziuneAcademicaAspSilverlight.Models.VideoContext();
IQueryable<Video> query = *_db.Videos;*
if (categorieId.HasValue && categorieId > 0)
{
query = query.Where(v => v.CategorieID == categorieId);
}
return query;
Change
IQueryable<Video> query =
to
IQueryable<Appname.Models.Video> query =
The reason for your error is that you have the type Video defined twice and because of using a short type name you accidentally reference not the one Video you should.
Also change it in the method's return value
public IQueryable<Appname.Models.Video> GetVideos( ... )
You seem to have two classes called Video. If you need both, you'll need to project from one to the other before your return statement:
return query.Select(dbVideo => new Appname.Video()
{
Prop1 = dbVideo.Prop1,
Prop2 = dbVideo.Prop2,
// etc.
});
Though you'll probably need to change the return type to an IEnumerable<> if you do that.
If you can just work with Appname.Models.Video, change IQueryable<Video> to IQueryable<Appname.Models.Video> in the method signature and the method body.
I am using this code to invalidate CloudFront Files using ASP.NET AWS SDK.
public bool InvalidateFiles(string[] arrayofpaths)
{
try
{
var client = AWSClientFactory.CreateAmazonCloudFrontClient(MY_AWS_ACCESS_KEY_ID, MY_AWS_SECRET_KEY);
CreateInvalidationResponse r = client.CreateInvalidation(new CreateInvalidationRequest
{
DistributionId = ConfigurationManager.AppSettings["DistributionId"],
InvalidationBatch = new InvalidationBatch
{
Paths = new Paths
{
Quantity = arrayofpaths.Length,
Items = arrayofpaths.ToList()
},
CallerReference = DateTime.Now.Ticks.ToString()
}
});
}
catch
{
return false;
}
return true;
}
I supplied a path like "/images/1.jpg" but it seems that the invalidation doesn't take place. I've waited half and hour and used hard refresh and cleared the cache and the image is the same. I've changed the image to look different so I can notice the difference if invalidation has occurred.
In the console I see that the invalidation took place, because I have the ID and in the status I see 'completed', but again, nothing changed in the image.
My question is how can I check that the invalidation takes place and make it work, it seems that I am missing something.
Also, is there an option to create is asynchronous, so I won't need to answer from Amazon.
Thanks.
We are rying to use WF with multiple tracking participants which essentially listen to different queries - one for activity states, one for custom tracknig records which are a subclass of CustomTrackingRecord.
The problem is that we can use both TrackingParticipants indivisually, but not together - we never get our subclass from CustomTrackingRecord but A CustomTrackingRecord.
If I put bopth queries into one TrackingParticipant and then handle everythign in one, both work perfectly (which indicates teh error is not where we throw them).
The code in question for the combined one is:
public WorkflowServiceTrackingParticipant ()
{
this.TrackingProfile = new TrackingProfile()
{
ActivityDefinitionId = "*",
ImplementationVisibility = ImplementationVisibility.All,
Name = "WorkflowServiceTrackingProfile",
Queries = {
new CustomTrackingQuery() { Name = "*", ActivityName = "*" },
new ActivityStateQuery() {
States = {
ActivityStates.Canceled,
ActivityStates.Closed,
ActivityStates.Executing,
ActivityStates.Faulted
}
},
}
};
}
When using two TrackingParticipants we have two TrackingProfile (with different names) that each have one of the queries.
in the track method, when using both separate, the lines:
protected override void Track(TrackingRecord record, TimeSpan timeout)
{
Console.WriteLine("*** ActivityTracking: " + record.GetType());
if (record is ActivityBasedTrackingRecord)
{
System.Diagnostics.Debugger.Break();
}
never result in the debugger hitting, when using only the one to track our CustomTrackingRecord subclass (ActivityBasedTrackingRecord) then it works.
Anyone else knows about this? For now we have combined both TrackingParticipants into one, but this has the bad side effect that we can not dynamically expand the logging possibilities, which we would love to. Is this a known issue with WWF somewhere?
Version used: 4.0 Sp1 Feature Update 1.
I guess I encounterad the exact same problem.
This problem occurs due to the restrictions of the extension mechanism. There can be only one instance per extension type per workflow instance (according to Microsoft's documentation). Interesting enough though, one can add multiple instances of the same type to one workflow's extensions which - in case of TrackingParticipant derivates - causes weird behavior, because only one of their tracking profiles is used for all participants of the respective type, but all their overrides of the Track method are getting invoked.
There is a (imho) ugly workaround to this: derive a new participant class from TrackingParticipant for each task (task1, task2, logging ...)

I think that this problem isn't caused by extension mechanism, since DerivedParticipant 1 and DerivedParticipant 2 are not the same type(WF internals just use polymorphism on the base class).
I was running on the same issue, my Derived1 was tracking records that weren't described in its profile.
Derived1.TrackingProfile.Name was "Foo" and Derived2.TrackingProfile.Name was null
I changed the name from null to "Bar" and it worked as expected.
Here is a WF internal reference code, describing how is the Profile selected
// System.Activities.Tracking.RuntimeTrackingProfile.RuntimeTrackingProfileCache
public RuntimeTrackingProfile GetRuntimeTrackingProfile(TrackingProfile profile, Activity rootElement)
{
RuntimeTrackingProfile runtimeTrackingProfile = null;
HybridCollection<RuntimeTrackingProfile> hybridCollection = null;
lock (this.cache)
{
if (!this.cache.TryGetValue(rootElement, out hybridCollection))
{
runtimeTrackingProfile = new RuntimeTrackingProfile(profile, rootElement);
hybridCollection = new HybridCollection<RuntimeTrackingProfile>();
hybridCollection.Add(runtimeTrackingProfile);
this.cache.Add(rootElement, hybridCollection);
}
else
{
ReadOnlyCollection<RuntimeTrackingProfile> readOnlyCollection = hybridCollection.AsReadOnly();
foreach (RuntimeTrackingProfile current in readOnlyCollection)
{
if (string.CompareOrdinal(profile.Name, current.associatedProfile.Name) == 0 && string.CompareOrdinal(profile.ActivityDefinitionId, current.associatedProfile.ActivityDefinitionId) == 0)
{
runtimeTrackingProfile = current;
break;
}
}
if (runtimeTrackingProfile == null)
{
runtimeTrackingProfile = new RuntimeTrackingProfile(profile, rootElement);
hybridCollection.Add(runtimeTrackingProfile);
}
}
}
return runtimeTrackingProfile;
}
Have a real puzzler here. I'm using Atalasoft DotImage to allow the user to add some annotations to an image. When I add two annotations of the same type that contain text that have the same name, I get a javascript permission denied error in the Atalasoft's compressed js. The error is accessing the style member of a rule:
In the debugger (Visual Studio 2010 .Net 4.0) I can access
h._rule
but not
h._rule.style
What in javascript would cause permission denied when accessing a membere of an object?
Just wondering if anyone else has encountered this. I see several people using Atalasoft on SO and I even saw a response from someone with Atalasoft. And yes, I'm talking to them, but it never hurts to throw it out to the crowd. This only happens in IE8, not FireFox.
Thanks, Brian
Updates: Yes, using latest version: 9.0.2.43666
By same name (see comment below) I mean, I created default annotations and they are named so they can be added with javascript later.
// create a default annotation
TextData text = new TextData();
text.Name = "DefaultTextAnnotation";
text.Text = "Default Text Annotation:\n double-click to edit";
//text.Font = new AnnotationFont("Arial", 12f);
text.Font = new AnnotationFont(_strAnnotationFontName, _fltAnnotationFontSize);
text.Font.Bold = true;
text.FontBrush = new AnnotationBrush(Color.Black);
text.Fill = new AnnotationBrush(Color.Ivory);
text.Outline = new AnnotationPen(new AnnotationBrush(Color.White), 2);
WebAnnotationViewer1.Annotations.DefaultAnnotations.Add(text);
In javascript:
CreateAnnotation('TextData', 'DefaultTextAnnotation');
function CreateAnnotation(type, name) {
SetAnnotationModified(true);
WebAnnotationViewer1.DeselectAll();
var ann = WebAnnotationViewer1.CreateAnnotation(type, name);
WebThumbnailViewer1.Update();
}
There was a bug in an earlier version that allowed annotations to be saved with the same unique id's. This generally doesn't cause problems for any annotations except for TextAnnotations, since they use the unique id to create a CSS class for the text editor. CSS doesn't like having two or more classes defined by the same name, this is what causes the "Permission denied" error.
You can remove the unique id's from the annotations without it causing problems. I have provided a few code snippets below that demonstrate how this can be done. Calling ResetUniques() after you load the annotation data (on the server side) should make everything run smoothly.
-Dave C. from Atalasoft
protected void ResetUniques()
{
foreach (LayerAnnotation layerAnn in WebAnnotationViewer1.Annotations.Layers)
{
ResetLayer(layerAnn.Data as LayerData);
}
}
protected void ResetLayer(LayerData layer)
{
ResetUniqueID(layer);
foreach (AnnotationData data in layer.Items)
{
LayerData group = data as LayerData;
if (group != null)
{
ResetLayer(data as LayerData);
}
else
{
ResetUniqueID(data);
}
}
}
protected void ResetUniqueID(AnnotationData data)
{
data.SetExtraProperty("_atalaUniqueIndex", null);
}
