    • In a computer system having a display and a keyboard, a computer readable medium includes instructions for invoking a message hook procedure based on a mouse message indicative of a mouse event. Instructions also provide for identifying at least one focus application that has a current keyboard focus and of converting the mouse message into a command for the focus application. The command is then sent to the focus application and the mouse message is prevented from being routed to any other applications. In one embodiment, the commands include the command to page forward or backward through pages of Internet documents. In other embodiments, instead of converting the mouse message into a command, the message hook procedure displays a graphical user interface based on the focus application and the mouse message. The graphical user interface includes one or more commands that the user may select. Based on the selection made by the user, the message hook procedure sends a corresponding command to the focus application.
    • 在具有显示器和键盘的计算机系统中,计算机可读介质包括用于基于指示鼠标事件的鼠标消息来调用消息挂钩过程的指令。 指令还提供了识别至少一个具有当前键盘焦点的焦点应用程序,并将鼠标消息转换为焦点应用程序的命令。 然后将命令发送到焦点应用程序,并且防止鼠标消息被路由到任何其他应用程序。 在一个实施例中,命令包括通过因特网文档的页面向前或向后翻页的命令。 在其他实施例中,消息挂钩过程不是将鼠标消息转换成命令,而是基于焦点应用和鼠标消息来显示图形用户界面。 图形用户界面包括用户可以选择的一个或多个命令。 基于用户做出的选择,消息挂钩过程向对焦应用发送相应的命令。

    • A circuit using a single transistor to detect the interface type to Which a combination pointing device is connected. The pointing device may be connected to a PS/2 interface, which generates a voltage greater than or equal to 0 volts, or a serial interface which generates a negative voltage. The transistor is activated when connected to the serial interface, and is inactive when connected to the PS/2 interface. The output of the transistor is sensed by a microcontroller within the pointing device. The microcontroller generates data for transmission to the PS/2 interface if the transistor is not active, and generates data for transmission to the serial interface if the transistor is active. An I/O pin in the microcontroller is used to sense the interface type and can also be used as an output in which the microcontroller generates control signals for use by the pointing device. This multitasking operation reduces the required pin count of the microcontroller, thus reducing cost.
    • 使用单个晶体管检测组合指示装置所连接的接口类型的电路。 指示装置可以连接到产生大于或等于0伏特的电压的PS / 2接口或产生负电压的串行接口。 晶体管连接到串行接口时被激活,当连接到PS / 2接口时,晶体管不活动。 晶体管的输出由定点设备内的微控制器感测。 如果晶体管不工作,微控制器产生传输到PS / 2接口的数据,并且如果晶体管有效,则生成用于传输到串行接口的数据。 微控制器中的I / O引脚用于检测接口类型,也可以用作微控制器产生控制信号以供指示设备使用的输出。 这种多任务操作减少了微控制器所需的引脚数,从而降低了成本。
