请设计程序,使其实现以秒计时的功能。首先定义一个watch类,它有两个私有变量begin、end分别表示开始时间、结束时间,有成员函数start()、stop()、show()分别用来设置开始时间、结束时间、显示持续时间。

Bing is a point-to-point bandwidth measurement tool (hence the b ), based on ping. Bing determines the real (raw, as opposed to available or average) throughput on a link by measuring ICMP echo requests roundtrip times for different packet sizes for each end of the link

This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other generic TCP/IP stacks today.

This tutorial attempts to get you started developing with the Win32 API as quickly and clearly as possible. It is meant to be read as a whole, so please read it from beginning to end before asking questions... most of them will probably be answered. Each section builds on the sections before it. I have also added some solutions to common errors in Appendix A. If you ask me a question that is answered on this page, you will look very silly.

Visual Basic 6.0可以通过调用API函数格式化一个磁盘,无论是软盘还是硬盘。 打开一个新的项目(工程1) ,如果你没有更改过缺省模式,那么Visual Basic 6.0会自动添加一个form1文件,在form1上添加一个命令控件,将下面的代码拷入。 Option Explicit Private Declare Function SHFormatDrive Lib"shell32"( ByVal Hend AS Long,ByVal Drive AS Long,ByVal FormatID AS Long,ByVal Options AS Long) as Long Private Sub FormatDisk(intDrive as integer,blnQuickFormat as Boolean) dim lngReturn As Long if (blnQuickFormat) then lngReturn= SHFormatDrive(0,intDrive,0&,1&) else lngReturn= SHFormatDrive(0,intDrive,0&,0&) end if end Sub Private Sub Command1_Click() call FormatDisk(0,True) End Sub 运行此程序。 注意FormatDisk函数的第一个变量很重要,他的值是0,1,2时代表格式化的分别是:A、B、C盘。

The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The library s compliance with the STL iterator and container standards means you can plug our abstractions into a wide variety of STL algorithms for data storage, searching and manipulation. In addition, the C++ reflection mechanism used by our library to bind to database tables allows us to add generic indexing and lookup properties to our containers with no special code required from the end-user. Because our code takes full advantage of the template mechanism, it adds minimal overhead compared with using raw ODBC calls to access a database.
