Please let e know your response.
Thanks in advance!!

You should use one of the CorDapp templates:
Java
Kotlin
These show you how to set up your project using Gradle.
You can then extend the template by following the Hello, World! tutorial here.

Symfony 3 - Add debug on each view render

I develop on a big new website some features.
There is lot of views and it's difficult to understand where the code is executed. I would like to add html comments on each render view of this website to help all developer to see where there are i try with kernel view but this listener is never lauch
If you known how i can do please ?
thx by advance
With your Symfony 3 app use http://localhost/app_dev.php/
When you call that URL Symfony will load the tool bar at the bottom that will provide the details you are looking for.
With Symfony 4 this is controlled by your environment settings.

Getting image from Class Library

I am doing a refactor of my Xamarin project, in which I want to build nuget-packages for my platform specific projects.
And since you can't make your "App.Droid", "App.iOS" and "App.UWP" into nugets I am using class libraries for this.
My problem is when I put my images (ordinary *.png-files) in my UWP-class library it won't work. It is working in both iOS and Android.
So my question is if anyone knows if this is possible, and if so how?
My current setup is as follows:
My UWP-project is named "App.UWP". This is the project i build and the project has the "App.xaml" and "MainPage.xaml".
I then created a "Class library (Universal Windows)" named "Company.Mobile.Core.UWP".
My "App.UWP" is referencing "Company.Mobile.Core.UWP".
I know I have a working connection between the two. My Custom renderers are in the "Company.Mobile.Core.UWP"-project and not in "App.UWP" and is working fine.
Cheers,
Tobias

IdentityServer4.Services.InMemory not working

I google a lot but not find any solution. Below is my problem :
I make a simple project where I use reference "IdentityServer4.Postgresql": "1.0.0"
where "using IdentityServer4.Services.InMemory" works perfectly.
But when I use "IdentityServer4.Postgresql": "2.0.0" then IdentityServer4.Services.InMemory always shows error.
That means version 2 of IdentityServer4.Postgresql not support IdentityServer4.Services.InMemory.
How can I use IdentityServer4.Services.InMemory for "IdentityServer4.Postgresql": "2.0.0"?
Thanks in advance.
IdentityServer4.Postgresql is not a part of the IdentityServer project, but sounds like a community contribution. You may have a better result by contacting the library creator.
Otherwise, you could try the official IdentityServer4.EntityFramework package that is maintained by the IdentityServer team in combination with an Entity Framework Core database provider for PostgreSQL.
The official quickstarts only show adding Entity Framework in the 8th quickstart. You'll have to do each one in succession up to the eighth one to fully understand / make sure to have the code you need.
After you have Entity Framework added to the configuration, you can support a Postgres database by just adding dependencies.

Has anyone created a TypeScript definition file for ractivejs?

I am working with ractivejs in a large team project where all of our client side javascript is created using TypeScript. I am wondering if anyone else has run in to the need for a TypeScript definition file for ractivejs? Thanks for any replies.
I have now started create a ractive.d.ts :)

In Flex, is it posible to identify if the code is runing on Web or AIR?

I'm coding an app that runs both in the web and on AIR, to avoid copying code arround, I figured I should do 3 kinds of projects on flex builder: Library, Web and AIR projects.
So all my code is on the Library project.
I have accessData.as that extends EventDispatcher to fetch web services and return them as an event. I plan on using this class to also fetch SQLite data for the desktop version, but to do so I need it to decide from wich source to get the data depending on if its Web or AIR.
Anyone know how to do this?
Please refer to this link Detect AIR versus Flash Player from an actionscript library Its more detailed.
You really should have two build targets, one for Web and one for AIR. And your code should be designed in a way that the rest of the system doesnt care what the implementing part is doing, only that it conforms to a certain interface. This way, each build simply replaces the implementing code for each desired platform.
You may find something useful under System or Capabilities in the docs.
Create 2 projects Air and Standalone and create 2 conditional compilation variables for example "standalone" and "air". (more here).
Go to Project->Properties->Flex Compiler and add
For air project:
-define=CONFIG::standalone,false -define=CONFIG::air,true
and for stanalone:
-define=CONFIG::debugging,true -define=CONFIG::air,false
In your code set:
CONFIG::standalone {
trace("this code will be compiled only when air=false and standalone=true");
}
CONFIG::air {
trace("this code will be compiled only when air=true and standalone=false");
}
umm... I just found out a way
var appName:String = Application.application.name;
this works since the web version is called "" and the desktop version is called " desktop"
but if anyone has a better way please go ahead.
thanks.
