I do it with a Dialog Box app. In the resource editor properties for the dialog resource, set Border=None and Title Bar=False to eliminate all border elements. In OnInitDialog, use the following to resize the dialog to the entire desktop:
我用一个对话框应用程序来做到这一点。在对话框资源的资源编辑器属性中，设置 Border=None 和 Title Bar=False 以消除所有边框元素。在 OnInitDialog 中，使用以下命令将对话框的大小调整为整个桌面：
CRect rcDesktop;
rcDesktop.left = GetSystemMetrics(SM_XVIRTUALSCREEN);
rcDesktop.right = rcDesktop.left + GetSystemMetrics(SM_CXVIRTUALSCREEN);
rcDesktop.top = GetSystemMetrics(SM_YVIRTUALSCREEN);
rcDesktop.bottom = rcDesktop.top + GetSystemMetrics(SM_CYVIRTUALSCREEN);
MoveWindow(rcDesktop, FALSE);
This code works on multiple monitors, unlike maximizing the window.
与最大化窗口不同，此代码适用于多个监视器。
No need to worry about making the window topmost, Windows will display it on a dedicated desktop with no other windows present.
无需担心将窗口置于最上方，Windows 会将其显示在没有其他窗口的专用桌面上。

I think removing the border from the dialog resource and showing the window as maximized (ShowWindow(SW_SHOWMAXIMIZED)) should do the job.
我认为从对话框资源中删除边框并将窗口显示为最大化 ( ShowWindow(SW_SHOWMAXIMIZED)) 应该可以完成这项工作。
As for topmost use the System Modalstyle in the dialog resource.
至于 topmost 使用对话框资源中的System Modal样式。
