问题描述

朋友，
我使用了WDK(7600.16385.1)镜像驱动程序，但仅显示一个简单的空白窗口，但我想将整个桌面复制到该窗口中.我尝试了一些实验，但没有成功.我在内核模式下看到驱动程序drvCopyBits()/DrvBitBlt()不会将数据从源表面复制到目标表面.这是窗口空白的原因吗?

我对镜像驱动程序非常陌生，因此任何帮助或任何指针都将对我有很大帮助.

如果您有任何示例代码可以将活动桌面复制到新窗口/文件中，请告诉我?

Hi frineds,
I have used WDK(7600.16385.1) mirror driver but i.e. only shows a simple blank window but I wanted to copy complete desktop into that window. I tried some experiments but could not get success. I saw in kernel mode driver drvCopyBits()/DrvBitBlt() are not copying data from source surface to destination surface. Is this the reason why window is showing blank?

I am very new to mirror driver so any help or any pointer will help me a lot.

If you have any sample code which will copy active desktop into a new window/file, please let me know?

推荐答案

朋友，我听说这个社区非常活跃，请帮帮我.

目前，我正在尝试实现DrvTransparentBlt().我读过，此功能的目的是将数据从设备控制的表面复制到GDI表面，反之亦然.但是我不知道如何实现它.任何示例代码也将帮助我了解在此函数中需要执行的所有计算.

我的主要目的是获取用户级别的显示/任何活动，并通过GDI调用将其发送给驱动程序.

任何信息来源都会对我有很大帮助.

期待您的回复.

Friends, I have heard that this community is very active, Please help me out.

Currently I am trying to implement DrvTransparentBlt(). I have read, purpose of this function is to copy data from device controlled surface to GDI surface and vice versa. But I have no clue how to implement it. Any sample code will also help me to understand what all calculation I need to do inside this function.

My main intension is to grab the display/any activity at user level and send it to driver through GDI calls.

Any source of information will help me a lot.

Looking forward to your response.
