How do I have to set a breakpoint in WinDGB in order to see the call to GC.Collect()? I already tried bp clr!SVR::GCHeap::GarbageCollect but it doesn't work...
I'm using .NET 4.5.1.
Never mind! I just figured it out:
bp clr!WKS::GCHeap::GarbageCollect

I need help. Is there any way to make a child in the firebase database from android studios with a variable? I want to create a child with text that the user enters into the application and it is saved in a variable.
Etc.: mFirebaseDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(MailVariable)
I try this line of code but my app was crash every time.
Is there any way? Please answer or refer me to the site where the solution is located.
Thank you.
(Note: I'm beginner and I'm getting ready for competition)
if your mFirebaseDatabase variable returning an instance of the FirebaseDatabase then that is wrong. Be careful with the return types of the sdks.
FirebaseDatabase.getInstance().getReference().child("Users").child(MailVariable)
the above will not return a type of FIrebaseDatabase
Yes you can! But you have to set value of that particular child too.
In Visual Studio, you get this when you step over a line while debugging:
I can't seem to find an equivalent in Rider. Is there something like it?
As per the comments to my original question, this feature still hasn't been implemented yet
As a workaround, if I really need to know the elapsed time, I've just been using a stop watch.
Example:
var sw = new Stopwatch();
sw.Start();
// Code you care about goes here
sw.Stop();
// Put breakpoint here, then use debugger to look at sw.ElapsedMilliseconds
I tried
#posts = Post.page(params[:page]).per_page(10)
and
#posts = Post.paginate(:page => 1, :per_page => 10)
but neither method works
undefined method `page' for Post:Class
undefined method `paginate' for Post:Class
How do you do pagination with mongoid?
You should use Kaminari https://github.com/amatsuda/kaminari
This works fine for me:
#posts = Post.paginate(:page => 1, :limit => 10).desc(:_id)
desc(:_id) is added so that latest posts could be listed first.
Still using will_paginate is also okay.
This thread has same issue: undefined method `paginate' for Array on Rails 3 with mongoid
The main point to fix the error is to add this line before the controller call paginate library:
require 'will_paginate/array'
It should be added to default config file if you use mongoid for the whole project.
Hope the explanation helpful.
Reference from origin gem source: https://github.com/mislav/will_paginate/wiki/Backwards-incompatibility at "WillPaginate::Collection" section.
P/S: this is just a work around if your query is not very large. If you want better performance, let's try mongoid-pagination gem, custom will_pagination gem or another pagination gem which supported Mongoid like kaminari.
A bit late, but for anyone else looking, I found 'will_paginate_mongoid'
https://github.com/lucasas/will_paginate_mongoid
Really straight forward and lets you simply do
collection.skip(20).limit(10)
Use the following gem.
Very helpful.

To update a bit the answers, now exists the Pagy gem, also much more performant (cpu/mem) than will_paginate and kaminari. This is a migration guide
silly thing, but it worked for me in sinatra after i added require 'mongoid-pagination'
to app.rb
Posting several years later, in case someone else faces the same challenge.
kaminari-mongoid was released in 2016, and is currently maintained.

All the goodness of Kaminiari for Mongoid, including appropriate handling of Mongoid::Criteria results, which was possibly the cause of the OP's error.
I've embedded an nsIWebBrowser in my application. Because I'm just generating HTML for it on the fly, I'm using OpenStream, AppendToStream, and CloseStream to add content. What I need is to add event listeners for mouse movement over the web browser as well as mouse clicks. I've read documentation and tried lots of different things, but nothing I have tried has worked. For instance, the code below would seem to do the right thing, but it does nothing:
nsCOMPtr<nsIDOMWindow> domWindow;
mWebBrowser->GetContentDOMWindow(getter_AddRefs(domWindow));
if (!mEventTarget) {
mEventTarget = do_QueryInterface(domWindow);
if (mEventTarget)
mEventTarget->AddEventListener(NS_LITERAL_STRING("mouseover"), (nsIDOMEventListener *)mEventListener, PR_FALSE);
}
Perhaps it isn't working because this is run during initialization, but before any content is actually added. However, if I add it during AppendStream, or CloseStream, it segfaults.
Please tell me a straightforward way to do this.
Well, here's the answer:
nsCOMPtr<nsIDOMEventTarget> cpEventTarget;
nsCOMPtr<nsIDOMWindow> cpDomWin;
m_pWebBrowser->GetContentDOMWindow (getter_AddRefs(cpDomWin));
nsCOMPtr<nsIDOMWindow2> cpDomWin2 (do_QueryInterface (cpDomWin));
cpDomWin2->GetWindowRoot(getter_AddRefs(cpEventTarget));
rv = cpEventTarget->AddEventListener(NS_LITERAL_STRING("mousedown"),
m_pBrowserImpl, PR_FALSE);
With the following code:
IEnumerable<int> LocalityIds = new List<int>();
PersonCollection pc =
new PersonCollection().
Where(Person.Columns.AddressLocalityId, SubSonic.Comparison.In, LocalityIds).
Load();
Although the initial collection is empty Subsonic still returns all records?!?!?!?!? Is this a bug or am i doing something wrong?
Thanks
I don't think we've setup collections to do this even though the Comparison is there. Have you tried Select().From().Where(..).In(LocalityIds).ExecuteAsCollection();
Just checked V2.2 and this still happens, when I have a bit of time I will try to submit a patch
