问题描述

大家好.我正在创建用于更改投影仪投影图像的简单应用程序.
现在，我要实现的是投影图像与桌面图像不同.
考虑简单的例子.我的应用程序将打印一个屏幕，并向其中添加一些位图.比它将发送到投影仪.虽然笔记本显示器上的原始图像仍然是相同的，但投影图像仍将包含此添加的位图.我正在使用GDI更改图像和c ++/cli，Windows窗体作为我的应用程序的基础.
希望你们能够理解并且更重要的是，你们知道解决此任务的方法.
提前谢谢.


好吧，至少我想出了一种肮脏"的方式来做到这一点.仅使用无边界的表格和扩展的第二个显示.还没有测试过，但是我强烈希望它可以解决问题.但是，仍然非常需要正确的方法



将OP的文本从答案带到这里

Hello everybody. I am creating simple application for altering image projected by projector.
Now what I want to achieve is for projected image to be different than desktop.
Consider simple example. My application would take a print-screen and add some bitmap to it. Than it will sent it to projector. While original image on notebook monitor is still the same projected image will contain this added bitmap. I am using GDI for altering image and c++/cli , windows forms as a base for my app.
Hope it is understandable and more importantly, that you guys know a way to solve this task.
Thanks in advance.


Well, at least I figured out a "dirty" way to do this. Just using form without borders and extended second display. No tested it yet but i have a strong feeling that it should do the trick. However correct way to do this is still desired very much
