Contains dynamic registry data , such as that used by virtual device drivers 包含动态注册表数据，例如，虚拟设备驱动程序使用的数据。
Some programs , such as virtual device drivers , do not require this default stack - growth mechanism 某些程序（如虚拟设备驱动程序）并不需要这种默认堆栈增长机制。
Design of a signal processing card for diode array detector and development of its virtual device driver 二极管阵列检测器信号处理卡的研制及其虚拟设备驱动程序的开发
A virtual device driver ( vxd ) for the card had to be designed to make the pci card work well in win9x operating system 作者开发了虚拟设备驱动程序vxd ，使该卡工作在windows9x环境中。
A new method that making use of vxd to enable win32 application to perform real - time control function is proposed . 4 提出了利用虚拟设备驱动程序技术使基于windows平台的应用程序实现实时控制的新方法。
For in the experiment system operator system ( os ) is windows9x , vxd is programed for a / d data acquisition card 由于系统采用了基于windows9x的操作平台，所以对所使用的数据采集卡编写了虚拟设备驱动程序( vxd ) 。
Is used to store dynamic registry data , such as that used by virtual device drivers and is supported only on windows 95 98 systems 用于存储动态注册表数据，如由虚拟设备驱动程序使用并仅受windows 95 98系统支持的数据。
So , the technique of developing virtual device driver with vtoolsd is presented after a brief introduction of windows98 virtual machine structure and primary knowledge of vxd 为此，本文在简单介绍windows98的虚拟机结构和一些vxd的基本知识的基础上，给出了用vtoolsd开发保护卡的虚拟设备驱动程序的方法。
Four main aspects of development of virtual device driver are analyzed . they are device initialization , communication of win32 application process and vxd , access of vxd to hardware and hardware interruption process in vxd 主要从设备初始化、 win32应用程序对vxd的通信、 vxd访问硬件设备和vxd处理硬件中断四个方面分析了虚拟设备驱动程序的开发。
Based on the hardware platform , the principle and development method of device driver under windows operating system are introduced . the development process of virtual device driver based on pci9052 is also provided 在完成硬件平台设计的基础上，本文还介绍了windows下设备驱动程序的原理及开发方法，并给出了基于pci9052的虚拟设备驱动程序的开发过程。
