QUESTION
Going nuts here...
Model:
...ANSWER
Answered 2020-May-22 at 08:59You're mapping code is fine and should work fine if everything is configured properly. I believe the issue that you are having is that while you have configured AM properly for your example, the actual mapper that is doing the work to translate from model to entity is not using your actual configuration. Like Eric, I ran the code you provided and it works fine....unless I comment out the actual mapping in the configuration. I think the reason you get this exception is because AM is attempting to convert using it's own convention mapping rather than your defined mapping. AM can figure out Id and Name automatically without configuration, but fails on city. You need to make sure that your _mapper is actually pointing to a "configured mapper".
If I run this (as you have it), the code works fine.

I have a route where I built two GET APIs
. I would like one to redirect from /download
to /zip
all while passing a parameter. The problem is I am getting a 404 for some reason the routes url is not being included in the redirect()
Here are the APIs.

is expecting a path parameter not a query parameter.
You should redirect like this
QUESTION
i am new to programming and especialy at programming ai. I am sorry if the problem is stupid or easy to fix. I have created a primitive flappy bird game with neural network to controll it. Every thing goes ok until all the birds die. After all birds die i am choosing the best bird, create Array of new population , set the new birds "brain" to equal to the best bird "brain", and finally i am mutate all the new population birds brain a tiny so they are not be the same. I tried to mutate using probability, mutate all the weights of new birds brain, set if statement so weights doesnt go below 1.0 or under -1.0. The result is the same , all the birds at the next generation (second) act like they are having the same "brain". Here are some code that i think is worth to check. I can place all the code but it is big.

...ANSWER
Answered 2020-May-12 at 06:40When you assign the brain of the i th bird to the lastbird.brain
in all of the new generation birds at birds.get(i).brain=lastbird.brain
, you are setting the references of all the brains of all the new birds to the same brain object. ie. any bird.brain reference points to the same brain object. So when you change (ie. mutate) one bird's brain, it is done on the common object pointed by all the references and it is reflected on all the birds at the same time.
You need to copy the contents of the brain object instead of pointing to the same object. You can do this by cloning or using copy constructors. Copy constructors are preferred over cloning. You need to replace birds.get(i).brain=lastbird.brain
with

I am trying to select the Wireless button on the pop-up that is generated in the same window. It does not generate any iFrames and I cannot locate any elements inside this Wifi-Connect window.
Anyone got any ideas?
I've tried

Answered 2019-Apr-18 at 11:29If it is not showing any locators and if its getting generated in the same window then chances are it can be an alert. If it is an alert then simply try driver.switchTo().alert().accept() or (any other action u want to perform). Hope that helped ...

Answered 2019-Apr-09 at 15:26As I see it you're trying to "start" the Mainwindow from another function. This works for all "Windows" by first creating an instance of them and then showing them as well.
QUESTION
I need to run a task to check the connection.
My windows should not be frozen during this check.
So I start the Task, and close my window at the end of this task.
But this returns an exception: InvalidOperationException:'The calling thread cannot access this object because another thread owns it'.
Like this :
...ANSWER
Answered 2019-Apr-09 at 09:37Use Dispatcher
to queue window closing logic on the unique UI thread.
Something like
Dispatcher.Invoke(
() =>
{
// close window here
});
Whatever is passed into .Invoke(...)
as a delegate, is invoked on the UI thread and hence has right to access all UI elements. It is common (and the only correct) way to deal with UI-mutations within non-UI threads.
QUESTION
I have a simple socket listener application. It needs to be able to receive requests and give a response and also send requests itself and receive the responses for them.
As soon as my application starts, it will start receiving in a separate thread and send a response. This part works fine.
However when I send requests through the SendRequest()
-Method, I need to filter incoming responses, so the correct responses go to the correct requets earlier made. I do this (as seen in code below) with the class ResponseHandler
, which lets me register a request and in return notifies my registered request, as soon as the correct response came in. A placed request should however time out after 10 seconds, so I used a CountdownEvent
, which waits these 10 seconds, but releases earlier, if the response came in earlier.
Problem: My CountdownEvent
waits always the whole 10 seconds and only after that, the thread, where I receive messages will continue and thus receive the response. How is this possible, when I receive on a different thread?
I would think, that my program continues to receive in that separate thread, even when the CountdownEvent.Wait()
is active.
Note: The awaited response really comes back instantly after I placed the request as seen with the NetworkTool WireShark. So the timeout is not correct.
Edit: In a simple WPF-Application, where the SendRequest() is called from a button, it works. Unfortunately, this means my big program is the problem.

...ANSWER
Answered 2018-Sep-07 at 15:21So, your PendingRequest
and ResponseHandler
classes are being accessed from different threads. So, there are a couple of things you need to do, for the sanity of your program:
a) Make sure that when you are adding and removing requests from your pending requests dictionary, you get a lock, because you are simultaneously accessing a shared datastructure from different threads. Otherwise you can corrupt your datastructure.
b) Your more immediate problem is the Await()
method in PendingRequest
. You are calling CountdownEvent.Wait()
without verifying if your response is already set. If your response is already set, it would mean that you would wait for 10 seconds before you process it. This can happen if your response arrives, even before you invoke CountdownEvent.Wait()
. In that case, CountdownEvent.Signal()
will just be ignored. You should change the PendingRequest.Wait()
as follows:
QUESTION
I try to display an array which I fetch from mongodb (Chrome networktool shows that I get it (response with articles)). I dont get any error but the articles arent shown in the template.
Here is the template:
...ANSWER
Answered 2017-Feb-18 at 19:37I once asked a similar question to this: custom created method error: "is not a function" with an answer from Günter Zöchbauer:
"If you cast JSON to a TypeScript class, all is happening is that you indicat to the static analysis it can safely assume the value being of that class, that doesn't actually change the JSON value at all and also doesn't make it an instance of that class."
Your problem is here: .then((r: Response) => r.json().data as Article[])
. You declared them as array of Article
but they aren't. It'll work but in reality they are (correct me if I'm wrong. It's a new topic for me too) simple objects.
You can add objects to an array of Article
but that doesn't mean the added objects turns into an Article
