CopyFile()

[qing760416112]

#include<windows.h>
int main()
{

HANDLE hFile;
HANDLE h;
CHAR written[1024]="first";
DWORD w;

hFile=CreateFile("first.txt",GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
h=CreateFile("second.txt",GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);

WriteFile(hFile,written,lstrlen(written),&w,NULL);
CopyFile("D:\Program Files\Microsoft Visual Studio\MyProjects\ab\first.txt","C:\Documents and Settings\Administrator\桌面\KJJ\third.txt",FALSE);


CloseHandle(hFile);
CloseHandle(h);


//DeleteFile("first.txt");


return 0;
}

大家帮我看看这个为什么就没有复制过去呢？？？？？

感觉是在路径上出错了，但又不清楚怎么改

[奔跑的北极熊]

CopyFile("D:\Program Files\Microsoft Visual Studio\MyProjects\ab\first.txt","C:\Documents and Settings\Administrator\桌面\KJJ\third.txt",FALSE);

将字符串中的‘\’改成'\\'

CopyFile("D:\\Program Files\\Microsoft Visual Studio\\MyProjects\\ab\\first.txt","C:\\Documents and Settings\\Administrator\\桌面\\KJJ\\third.txt",FALSE);

谢谢大家了 就是以上大家说的这个错误

[qing760416112]

#include<windows.h>
#include<stdio.h>

DWORD ReadFileContent(LPSTR szFilePath)
{
HANDLE hFileRead;
LARGE_INTEGER liFileSize;
BYTE lpFileDataBuffer[32];
DWORD dwReadSize;
LONGLONG liTotalRead=0;

hFileRead=CreateFile(szFilePath,GENERIC_READ,GENERIC_READ ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);//OPEN_EXISTING 文件必须已经存在。由设备提出要求

if(hFileRead==INVALID_HANDLE_VALUE)
{

printf("打开文件失败: %d\n",GetLastError());


}
if(!GetFileSize(hFileRead,NULL))//这里把NULL改为&liTotalRead，为什么出错

{

printf("获取文件大小失败：%d",GetLastError());


}


else
{
printf("文件大小为: %d",liFileSize.QuadPart);

}


while(TRUE)
{

DWORD i;



if(!ReadFile(hFileRead,lpFileDataBuffer,32,&dwReadSize,NULL))
{

printf("读文件错误: %d",GetLastError);
break;
}

printf("读取了%d个字节,文件的内容是：",dwReadSize);

for(i=0;i<dwReadSize;i++);
{

printf("0x%x",lpFileDataBuffer[i]);

}


printf("\n");
liTotalRead+=dwReadSize;
if(liTotalRead==liFileSize.QuadPart)
{
printf("读文件结束\n");
break;

}



}




CloseHandle(hFileRead);
return 0;
}


int main(void )
{

ReadFileContent("C:\\Documents and Settings\\Administrator\\桌面\\TEST.txt");

return 0;
}
//运行的时候出现打开文件失败：87
//帮忙修改下

CopyFile("D:\Program Files\Microsoft Visual Studio\MyProjects\ab\first.txt","C:\Documents and Settings\Administrator\桌面\KJJ\third.txt",FALSE);




将字符串中的‘\’改成'\\'

这样的程序编译时应该会报错啊 （警告？） 当你的程序需要用 """ "\" 等字符时 都需要在前面加上转义字符"\" .最常见的应该是 \n\t 吧

[zwhate]

确实路径错了，“\”应该用"\\"来表示

[na_he]

CloseHandle(hFile);
CloseHandle(h);

这两句最好也放在copyfile之前比较合理。

怎么没人回答呀。哎 ，过了12点要是还不能解决的话 只能再发帖了

用SHFileOperation()
