kandi X-RAY | CControl Summary
CControl is a library written in 100% C code. No external libraries and 100% platform independent. The purpose with this library is to fit advanced tools for really small embedded systems or desktop as well. Here I have focused on practical numerical methods and selected the methods that works best in practice. It has been a lot of work finding the best methods and best algorithms. Many examples can be found in the scr folder.

QUESTION
I know there are questions similar to this one, but nothing seems to help make things click. I know in MVVM there is a Model, ViewModel, and View. I will try to make this simple so I can understand what components go inside which. In this particular code I want to be able to control the visibility of the side bar menu with the top bar menu. Then I will create a navigation for the side bar menu, but trying to figure out what goes where seems very hard and I am not sure why.
FYI: If you are trying to recreate the namespaces were changed and I am using Material Design NuGet Package
This should be the Base Model known as the BindableBase (I Think?) The Model contains the INotifyPropertyChanged, but because this is a base I shouldn't have any variables in this or should I?
Model:
...ANSWER
Answered 2021-Mar-16 at 18:02Now, I'm no expert on MVVM, but I have worked with it in the past, so let me try to clarify some things. To anyone more knowledgeable: please feel free to correct me.
This should be the Base Model known as the BindableBase (I Think?) The Model contains the INotifyPropertyChanged, [...]
Since you didn't post the ViewModelBase
source I'm going assume it just inherits from BindableBase
and doesn't add anything else. In that case he only reason for the separation I could think of is to allow models to inherit from BindableBase
.
This is not part of the code idea behind MVVM, models are expected to be completely separate from any ui logic and therefore usually do not implement the INotifyPropertyChanged
interface.
(As an aside, it is of course possible to have models implement INotifyPropertyChanged
, but as you're trying to understand the core MVVM concepts I think this just adds confusion).
As explained here, the model itself does not contain any logic related to interaction with the UI, but just the data and logic required for the underlying tasks your application is trying to solve.
I usually think of it this way:
If I want to have both a command line version and a UI app, which parts would I move to a library that can be included by both versions?
The answer to that is most likely what should be in your models.
If the application's sole purpose is to experiment with the WPF bindings, it doesn't need any such logic and therefore won't have any models.
Let's take a more detailed look at your BindableBase
class. My first advice would be to merge it with the ViewModelBase
class and have all view models inherit from it.
Its purpose is to handle everything around the PropertyChanged
event so you don't have to include that code in every view model, and it should indeed not contain any fields or properties apart from the PropertyChanged
event.
The OnPropertyChanged
method is supposed to receive the name of the changed property and call the PropertyChanged
event handler. Note that your implementation erroneously always passes the string "sender"
as the property name due to the nameof
operator. This is most likely why your visibility change events are never received.
The name sender
is also usually used to refer to the object firing an event (note how the first parameter of the PropertyChangedEventHandler
delegate is called sender
and you're passing this
).
In addition you might want to look at the CallerMemberName
attribute, with it you don't always have to manually specify the property name.
Apart from that I'm a bit confused what the purpose of the ObjectSender
property and your constructor is. If I'm not missing anything, ObjectSender
will likely be null
when the Task
in the constructor is run and the PropertyChanged
event won't have any subscribers, so nobody is going to act on that fired event anyway.
Applying all of these points, we end up with something like this:
QUESTION
I did a program that I wished to distribute to my co-workers, they are not VBA oriented. So I wish to distribute it easily.
I created an Add-in, when install the add-in needs to create a custom Ribbon. I tried my best, but I cannot find easy to understand documentation.
My code is as follow :
...ANSWER
Answered 2021-Jan-28 at 23:44Here's an example of how you can do it without using any external application, just a text editor. But you will have to be careful to write XML code properly, or the excel file may not open correctly (make a backup copy).
You will create a folder named "customUI" and, inside that folder, a file named "customUI.xml"
You will write all your Ribbon details inside "customUI.xml". I wrote this example, covering the issues you listed: Big buttons and icons (Images list in https://bert-toolkit.com/imagemso-list.html) / Tooltip description (screentip and supertip) / Ribbon name (tab label) / Group names (group labels)
QUESTION
We are sending logs directly from Filebeats to Elasticsearch without Logstash.
Logs can contain JSON in different fields that also need to be parsed. I have created a pipeline to parse logs, tested it in the developer console, and output was as expected. I have set Filebeat to send logs to this pipeline by adding 'pipeline: application_pipeline' to filebeat.yml. But in Index Management, I see only my docs.
How to check if Filebeat is sending these logs to the pipeline?
log example:
...ANSWER
Answered 2020-Jul-31 at 08:59If you run GET _nodes/stats/ingest
, you're going to see the usage statistics for your pipeline in nodes.xyz.ingest.pipelines.application_pipeline
Another thing worth noting is that you could also do the same thing in Filebeat itself without resorting to using an ingest pipeline simply by defining a decode_json_fields
processor, like this:
QUESTION
This is a follow-up to the following question: Can't set Userform.KeyPreview to true
To recap: the goal is to build a form with some command buttons and a frame containing check boxes. The check boxes are dynamically populated at userform_initialize
in the frame so the user can scroll through them. My problem was with keyboard shortcuts. It wasn't possible to brute force write KeyDown handlers for each of the checkboxes because I don't know which ones will exist. Unfortunately, Excel doesn't support KeyPreview
so I had to mock up my own version. Thank you to @UGP for giving me promising avenues that seem to work, but not quite...
First, this is my class module called clsReasonPickKP
. I create a new instance for each checkbox to listen for KeyDown
events:
ANSWER
Answered 2017-Aug-13 at 20:46It turns out that the problem was so simple and right in front of my eyes. I just had to make the keyPreviewer
and keyPreviewCollection
variables public in my userform code module.
That still doesn't answer why breaking code execution after adding the object to the collection made VBA treat it as public, but just happy that it all works.

QUESTION
I have a search box which is using the jqueryUI .autocomplete
to get data via AJAX to give suggestions. The problem is that when a user hits enter before the autocomplete AJAX call to the source is done an error pops up in an alert box. "AJAX Error 0"
I assume when the user hits "Enter" when in the search box the browser is automatically stopping the AJAX call which resulting in a bad AJAX response which is triggering jqueryui to pop an error. Is there anyway to make this not happen? Here is some of the sample code of the autocomplete:
...ANSWER
Answered 2019-Oct-08 at 08:12The browser submits the form by default if you hit enter. While the ajax-request needs time (if not delivered from browser-cache), the browser-form-submit fires immediately and breaks your running ajax-request. As result you see those ajax error.
Maybe you can set a helper-variable if you press Enter and skip the JSON-function, if this var is true.

QUESTION
I can't find out, where my problem is. I get the following error:
Nest can't resolve dependencies of the BService (?, AService). Please make sure that the argument at index [0] is available in the CModule context.
I have 3 Modules, A, B, C.
C should be able to use services from B, and B should call services from A.
A and B have TypeOrm imports and an entity each.
Here is the code:
app.modules.ts:
...ANSWER
Answered 2019-Aug-06 at 16:38In your CModule
you do not need to define providers: [BModule]
as you will overwrite the value given from BModule
. As BModule
already exports BService
you shouldn't need to do anything other than import BModule
into your CModule
then you can use BService
with no problems.
Side remark: is there any reason you have dependencies across your modules? Most of the time if you can keep from importing other modules if it isn't necessary it'll make a lot of your code easier to work with.
