Win32 複製檔案

第一種方法：

#include "stdafx.h"#include <Windows.h>#include <stdio.h>#define BUF_SIZE 256int _tmain(int argc, _TCHAR* argv[]){HANDLE hIn,hOut;DWORD nIn,nOut;CHAR Buffer[BUF_SIZE];if (argc!=3){printf("Usage: cpW file1 file2\n");return 1;}hIn=CreateFile(argv[1],GENERIC_READ,0,NULL,OPEN_EXISTING,0,NULL);if (hIn==INVALID_HANDLE_VALUE){printf("Cannot open input file. Error:%x\n",GetLastError());return 2;}hOut=CreateFile(argv[2],GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);if (hOut==INVALID_HANDLE_VALUE){printf("Cannot open output file. Error:%x\n",GetLastError());return 3;}while (ReadFile(hIn,Buffer,BUF_SIZE,&nIn,NULL)&&nIn>0){WriteFile(hOut,Buffer,nIn,&nOut,NULL);if (nIn!=nOut){printf("Fatal write error:%x\n",GetLastError());return 4;}}CloseHandle(hIn);CloseHandle(hOut);return 0;}

第二種方法： 用win32便利函數

#include "stdafx.h"#include <Windows.h>#include <stdio.h>int _tmain(int argc, _TCHAR* argv[]){if (argc!=3){printf("Usage: cpW file1 file2\n");return 1;}if (!CopyFile(argv[1],argv[2],false)){printf("copy file Error:%x\n",GetLastError());return 2;}return 0;}

程式運行，dos下，3個參數。

*.exe "源檔案名稱" "目標檔案名稱"

三個檔案在同一目錄下
