如何用API实现文件COPY？

[wsansan]

程序段如下：

int nOk;
char strSrc[]= "d:\\temp.txt" ;
char strDst[]= "c:\\temp1.txt" ;
char strTitle[]= "File copying" ;

//进度题头
SHFILEOPSTRUCT FileOp;
//FileOp.hwnd = m_hWnd
FileOp.wFunc = FO_COPY ;
FileOp.pFrom = strSrc ;
FileOp.pTo = strDst ;
FileOp.fFlags = FOF_ALLOWUNDO ;
FileOp.hNameMappings = NULL ;
FileOp.lpszProgressTitle = strTitle ;

//执行文件拷贝
nOk=SHFileOperation(&FileOp);

if(nOk)
ShowMessage("There is an error!");
else
ShowMessage("File copy sucessfull!");

if(FileOp.fAnyOperationsAborted)
ShowMessage("Operation was aborted!");

但一直执行不对，请高手指教！

char strSrc[]= "d:\\temp.txt\0" ;
char strDst[]= "c:\\temp1.txt\0" ;
char strTitle[]= "File copying" ;
