Getting HWND off of CoreWindow object in UWP

by

This COM interface is only directly accessible to C++ code. In C# you have to declare it yourself and make it match the interface declaration in C:\Program Files (x86)\Windows Kits\10\Include\10.0.10586.0\winrt\CoreWindow.idl. Like this: using System.Runtime.InteropServices; … [ComImport, Guid(“45D64A29-A63E-4CB6-B498-5781D298CB4F”)] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] interface ICoreWindowInterop { IntPtr WindowHandle { get; } bool MessageHandled { set; } } Obtaining the interface … Read more

For example, import win32gui def … Read more

It is not inaccurate. You create a top-level window with CreateWindowEx(). Which looks like this: HWND WINAPI CreateWindowEx( _In_ DWORD dwExStyle, _In_opt_ LPCTSTR lpClassName, _In_opt_ LPCTSTR lpWindowName, _In_ DWORD dwStyle, _In_ int x, _In_ int y, _In_ int nWidth, _In_ int nHeight, _In_opt_ HWND hWndParent, _In_opt_ HMENU hMenu, _In_opt_ HINSTANCE hInstance, _In_opt_ LPVOID lpParam ); … Read more
