How could I know if I'm developing a c++/cx or c++/WinRT UWP application?












3















I'm creating a c++ UWP application and I want this app to be c++/WinRT because I read that c++/cx is not supported anymore.

And this is how I created my application.

VS 2017 -> File -> New -> Project... -> Visual C++ -> Windows Universal -> Blank App (Universal Windows)


I'm sorry for this basic question but I couldn't find out if my app is a c++/WinRT or not.

    Both C++/CX and C++/WinRT are supported. That said, some newer compiler features (like two-phase name lookup) are not compatible with the C++/CX extensions. The default C++ Blank App is using C++/CX which you can see because of the use of ref class.

C++/CX and C++/WinRT do not generate different application types. Even if C++/CX weren't supported anymore (it still is), an application compiled using C++/CX would still continue to run. C++/CX is purely a language-level compiler setting, that generates native code just like C++/WinRT.



You opt in to C++/CX by setting the /ZW (Windows Runtime Compilation) compiler option. If that compiler option isn't present, you aren't using C++/CX. The Blank App (C++/WinRT) project template (available after installing the C++/WinRT Visual Studio extension) doesn't set the /ZW compiler option. The Blank App (Windows Universal), on the other hand, does set the /ZW compiler option.

    Most of the UWP templates that come with Visual Studio are set up to use the C++/CX extensions (i.e. /ZW). You can install C++/WinRT project and item templates from Visual Studio Marketplace. I also have C++/WinRT variants of basic Direct3D projects on GitHub.

Create new schema in PostgreSQL using DBeaver

Image
0 At the beginning of my current job I had limited access to DB but recently my role is changed to superuser, admin, and owner. My colleague who was the previous DB admin is able to create a schema or change the permissions as there is a permission tab in the properties and he can change permissions by clicking easily. Would you please let me know how I can create schema and change permissions as well? Why his dbeaver looks different from me? He can easily right click on the schema folder on top of all schemas on the left side column and select create new schema while I do not have that, like the following picture I found on the internet. postgresql database-schema dbeaver share | improve this question

Deepest pit of an array with Javascript: test on Codility

Image
0 $begingroup$ This is the question from a Codility test, as a task in an interview: DeepestPit - problem description A non-empty zero-indexed array A consisting of N integers is given. A pit in this array is any triplet of integers (P, Q, R) such that: ·         0 ≤ P < Q < R < N; ·         sequence [A[P], A[P+1], ..., A[Q]] is strictly decreasing, i.e. A[P] > A[P+1] > ... > A[Q]; ·         sequence A[Q], A[Q+1], ..., A[R] is strictly increasing, i.e. A[Q] < A[Q+1] < ... < A[R]. The depth of a pit (P, Q, R) is the number min {A[P] − A[Q], A[R] − A[Q]}. For example, consider array A consisting of 10 elements such that: A[0] = 0 A[1] = 1 A[2] = 3 A[3] = -2 A[4] = 0 A[5] = 1 A[6] = 0 A[7] = -3 A[8] = 2 A[9] = 3 Triplet (2, 3, 4) is
