OneCore.Net.WIN.WinAPI 1.0.0

OneCore.Net.WIN.WinAPI Library

Overview

OneCore.Net.WIN.WinAPI is an internal library that provides low-level WinAPI bindings used by other OneCore libraries; it is not intended for standalone use and remains incomplete by design.

Features

• Dwmapi: Access to the WinAPI methods within the "dwmapi.dll"
• Kernel32: Access to WinAPI methods within the "kernel32.dll".
• Shell32: Access to WinAPI methods within the "shell32.dll".
• User32: Access to WinAPI methods within the "user32.dll".
• UxTheme: Access to WinAPI methods within the "uxtheme.dll".
• Data: Values and structures to use within any of those above. Like WM (WindowMessages), WH (WindowHandle) and many more.

Getting Started

1. Installation:

   • Install the OneCore.Net.WIN.WinAPI library via NuGet Package Manager:

   dotnet add package OneCore.Net.WIN.WinAPI
   

2. Usage:

   • Direct access the objects like

   User32.ShowWindow(windowHandle, WindowShowStyle.Restore);
   

   • Or a wrapper

   public class Demo
   {
       public Demo(IUser32 user32)
       {
           _user32 = user32;
       }
   
       public void RestoreWindow(Window window)
       {
           var windowHandle = ((HwndSource)PresentationSource.FromVisual(window))!.Handle;
           _user32.ShowWindow(windowHandle, WindowShowStyle.Restore);
       }
   }
   

Example

• Target

  public class Demo
  {
      public Demo(IUser32 user32)
      {
          _user32 = user32;
      }
  
      public void RestoreWindow(Window window)
      {
          var windowHandle = ((HwndSource)PresentationSource.FromVisual(window))!.Handle;
          _user32.ShowWindow(windowHandle, WindowShowStyle.Restore);
      }
  }
  

• UnitTest

  public class DemoTests
  {
      private Demo _target,
  
      [Setup]
      public void Setup()
      {
          _user32 = new Mock<IUser32>();
          _target = new Demo(_user32.Object);
      }
  
      [Test]
      public void RestoreWindow_CalledAfterMinimizedFromNormal_RestoresTheWindowBackToNormal()
      {
          var window = Utils.OpenDummyWindow();
          window.WindowState = WindowState.Normal;
  
          window.WindowState = WindowState.Minimized;
          _target.RestoreWindow(window);
  
          _user32.Verify(x => x.ShowWindow(It.IsAny<nint>(), WindowShowStyle.Restore), Times.Once());
          Assert.That(window.WindowState, Is.EqualTo(WindowState.Normal));
      }
  
      [Test]
      public void RestoreWindow_CalledAfterMinimizedFromNormal_RestoresTheWindowBackToMaximized()
      {
          var window = Utils.OpenDummyWindow();
          window.WindowState = WindowState.Maximized;
  
          window.WindowState = WindowState.Minimized;
          _target.RestoreWindow(window);
  
          _user32.Verify(x => x.ShowWindow(It.IsAny<nint>(), WindowShowStyle.Restore), Times.Once());
          Assert.That(window.WindowState, Is.EqualTo(WindowState.Maximized));
      }
  }
