将其他进程的窗口移动到另一个虚拟桌面

Question

所以我在Windows 10下实现了类似win-tab的界面.我试图将其他进程的窗口移动到另一个虚拟桌面.使用此问题的 API,我已经可以将自己的应用程序移动到任何桌面.但是当我在调用MoveWindowToDesktop(IntPtr TopLevelWindow,Guid CurrentDesktop)时移动其他窗口时,我得到了E_ACCESSDENIED作为返回码.在这个Github项目中,有人设法将DLL挂钩到其他进程,因此用户可以成功触发此函数.

我怎样才能做到这一点？

这可以使用 com 来实现VirtualDesktopManagerInternal

该对象及其依赖对象具有不同的 CLSID，具体取决于 Windows 的构建版本。

这里的示例代码被高度精简，只够在 Windows build 22000 上运行（在我的例子中，在 Windows 11 上测试它工作正常）。

您可以在这里看到一个非常详细的 .NET 库，它可以处理具有虚拟桌面的所有 Windows 版本： github VirtualDesktop

无论如何，这是在 Windows 11 上经过测试并运行的最少代码。

COM 导入部分：

static Guid CLSID_VirtualDesktopManagerInternal = new Guid("c5e0cdca-7b6e-41b2-9fc4-d93975cc467b");
static Guid CLSID_IVirtualDesktopManagerInternal = new Guid("b2f925b9-5a0f-4d2e-9f4d-2b1507593c10"); //windows version 22000
static Guid CLSID_ImmersiveShell = new Guid("C2F03A33-21F5-47FA-B4BB-156362A2F239");

要放入您的方法中的代码：

IServiceProvider10 shell = (IServiceProvider10)Activator.CreateInstance(Type.GetTypeFromCLSID(CLSID_ImmersiveShell));
IVirtualDesktopManagerInternal managerInternal = (IVirtualDesktopManagerInternal)shell.QueryService(CLSID_VirtualDesktopManagerInternal, CLSID_IVirtualDesktopManagerInternal);
int numberOfDesktops = managerInternal.GetCount(IntPtr.Zero);
IApplicationViewCollection applicationViewCollection = (IApplicationViewCollection)shell.QueryService(CLSID_IApplicationViewCollection, CLSID_IApplicationViewCollection);
            
//window you want to move
IntPtr hwnd = PutHwndOfTheWindowYouWantToMoveHere;
IApplicationView applicationView = applicationViewCollection.GetViewForHwnd(hwnd);

//virtual desktop you want to move to, in this example the desktop at index 0
uint virtualDesktopIndex = 0; //index of the virtual desktop you want ot move the window into
IObjectArray allDesktops = managerInternal.GetDesktops(IntPtr.Zero);
IVirtualDesktop firstVVD = (IVirtualDesktop)allDesktops.GetAt(virtualDesktopIndex, typeof(IVirtualDesktop).GUID);

//the move function
managerInternal.MoveViewToDesktop(applicationView, firstVVD);
