SHFileOperation
函数功能描述:文件操作，与 Shell 的动作相同.
函数原型：
#include<shellapi.h>
WINSHELLAPI int WINAPI SHFileOperation(LPSHFILEOPSTRUCT lpFileOp);
参数：
typedef struct _SHFILEOPSTRUCT
{
HWND hwnd; //父窗口句柄
UINT wFunc; //要执行的动作
LPCTSTR pFrom; //源文件路径，可以是多个文件
LPCTSTR pTo; //目标路径，可以是路径或文件名
FILEOP_FLAGS fFlags; //标志，附加选项
BOOL fAnyOperationsAborted; //是否可被中断
LPVOID hNameMappings; //文件映射名字，可在其它 Shell 函数中使用
LPCTSTR lpszProgressTitle; // 只在 FOF_SIMPLEPROGRESS 时，指定对话框的标题。
} SHFILEOPSTRUCT, FAR *LPSHFILEOPSTRUCT;
=======================
wFunc 可以为：
/FO_MOVE 0x0001 移动文件
FO_COPY 0x0002 复制文件
FO_DELETE 0x0003 删除文件，只使用 pFrom
FO_RENAME 0x0004 文件重命名
fFlags可以为：
FOF_MULTIDESTFILES 0x0001 //pTo 指定了多个目标文件，而不是单个目录
FOF_CONFIRMMOUSE 0x0002
FOF_SILENT 0x00044 // 不显示一个进度对话框
FOF_RENAMEONCOLLISION 0x0008 // 碰到有抵触的名字时，自动分配前缀
FOF_NOCONFIRMATION 0x0010 // 不对用户显示提示
FOF_WANTMAPPINGHANDLE 0x0020 // 填充 hNameMappings 字段，必须使用 SHFreeNameMappings 释放
FOF_ALLOWUNDO 0x0040 // 允许撤销
FOF_FILESONLY 0x0080 // 使用 *.* 时, 只对文件操作
FOF_SIMPLEPROGRESS 0x0100 // 简单进度条，意味者不显示文件名。
FOF_NOCONFIRMMKDIR 0x0200 // 建新目录时不需要用户确定
FOF_NOERRORUI 0x0400 // 不显示出错用户界面
FOF_NOCOPYSECURITYATTRIBS 0x0800 // 不复制 NT 文件的安全属性
FOF_NORECURSION 0x1000 // 不递归目录
返回值：
函数成功返回 0 ，失败返回非 0 。
例子：
1. 将 C:\Test.txt 拷贝到 D:\
SHFILEOPSTRUCT lpsh;
ZeroMemory(&lpsh,sizeof(lpsh));
lpsh.hwnd= HWND_DESKTOP;
lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
lpsh.wFunc=FO_COPY; // FO_MOVE 则是移动
lpsh.pFrom= "C:\Test.txt";
lpsh.pTo = "D:\"
if( 0 != SHFileOperation(&lpsh))
{
AfxMessageBox("复制文件出错,请检查");
return ;
}
2. 删除 D:\Test.txt
SHFILEOPSTRUCT lpsh;
ZeroMemory(&lpsh,sizeof(lpsh));
lpsh.hwnd= HWND_DESKTOP;
lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
lpsh.wFunc=FO_DELETE;
lpsh.pFrom= "D:\Test.txt";
if( 0 != SHFileOperation(&lpsh))
{
AfxMessageBox("删除文件出错,请检查");
return ;
}
3.重命名
SHFILEOPSTRUCT lpsh;
ZeroMemory(&lpsh,sizeof(lpsh));
lpsh.hwnd= HWND_DESKTOP;
lpsh.fFlags=FOF_NOCONFIRMATION|FOF_SIMPLEPROGRESS ;
lpsh.wFunc=FO_RENAME;
lpsh.pFrom= "D:\Test.txt";
lpsh.pTo = "D:\Test2.txt";
if( 0 != SHFileOperation(&lpsh))
{
AfxMessageBox("重命名文件出错!");
return ;
}
注意事项：
参数pTo、pFrom必须是以双0 结束的，原文为：
pFrom
Pointer to a buffer that specifies one or more source file names. Multiple names must be null-separated. The list of names must be double null-terminated.
a.如果是直接赋值：
WCHAR strSrc[MAX_PATH] = _T("g:\\123");
WCHAR strDst[MAX_PATH] = _T("g:\\456");
这样就可以成功编译。
b.如果pTo、pFrom从CString获得，则：
WCHAR SrcFolder[MAX_PATH],DestFolder[MAX_PATH];
wcscpy_s(SrcFolder, Source);
wcscpy_s(DestFolder,m_Path);
SrcFolder[wcslen(SrcFolder) + 1] = 0;
DestFolder[wcslen(DestFolder) + 1] = 0;（其中，Source与m_Path是在其他地方获取的值）
造成这种差异的原因是：CString在结尾并没有"\0"，所以需要我们添加。
