Windows:是否*可能*创建(虚拟)视频卡驱动程序? [英] Windows: Is it *possible* to create a (virtual) video card driver?

问题描述

我想创建一个虚拟监视器.这将起作用的方式是虚拟监视器将出现在我桌面上的窗口中.就 Windows 而言，它只是另一台显示器.

i want to create a virtual monitor. The way this would work is that the virtual monitor would appear in a window on my desktop. As far as Windows knows it is just another monitor.

我突然想到，作为一个实际问题，它必须作为视频卡驱动程序来完成(即视频不是通过电线连接到 LCD 面板，而是进入桌面上的另一个窗口).

It occurs to me that it would, as a practical matter, have to be done as video card driver (i.e. rather than the video going out a wire to an LCD panel, it would go into another window on the desktop).

从技术上讲，我所描述的事情可能吗?(从 DDK 的角度来看)

Does what i'm describing sound, technically, possible? (from a DDK point of view)

注意:我不能使用虚拟电脑，因为没有任何虚拟电脑的分辨率足以满足我的需要.也因为这不是我所要求的.

Note: i can't use a virtual pc, because no virtual PC has resolutions high enough for my needs. Also because it's not what i asked for.

注意:我的理由不重要，但我可以补充一些:

Note: My reasons are unimportant, but i can make some up:

• 我想在高 dpi 设置 (288dpi) 下测试我的应用程序)
• 我想创建一个我的 iPad 可以 VNC 的显示器
• 家庭电视在主显示器上运行
• 劫机者正在监视公交车，如果他怀疑我们让乘客下车
• 我正在努力扩展人类知识和理解的极限，以造福全人类

推荐答案

我想说这绝对是可能的，因为这就是虚拟化工具为他们的来宾实用程序所做的事情，但我无法详细告诉您如何做到这一点.我建议以 VirtualBox 来宾驱动程序代码为起点:http://www.virtualbox.org/browser/trunk/src/VBox/Additions/WINNT/Graphics

I'd say it's definitely possible, since that's what virtualization tools do for their guest utilities, but I wouldn't be able to tell you how in details. I'd suggest looking at the VirtualBox guest driver code as a starting point: http://www.virtualbox.org/browser/trunk/src/VBox/Additions/WINNT/Graphics
