Question

void CJob1Dlg::OnButton1() 
{
// TODO: Add your control notification handler code here CFile cFile;
char pbuf[100000];
char* pFileName = "D:\SearchEngine\1.txt";
if( cFile.Open( pFileName, CFile::modeCreate | CFile::modeWrite) )
{ UINT nBytesRead = cFile.Read( pbuf, cFile.GetLength());
CString str;
        str=pbuf;
str=str.Right((str.GetLength()-str.Find("value=")));
str=str.Left(str.Find("35303920"));
AfxMessageBox(str);

大家帮分析下原因吧，谢谢~~~

Answer 1

你想要的是什么字符串？ 注意那文件里有好多个“value=”

Answer 2

"D:\SearchEngine\1.txt";
"D:\\SearchEngine\\1.txt"; 

Answer 3

这点提醒我了：“value=”我换成了第一个数字："37122368"
结果还是弹不出来。

Answer 4

char* pFileName = "D:\\SearchEngine\\1.txt"; cFile.Open( pFileName, CFile::modeCreate  ¦ CFile::modeWrite)
模式不对吧，这是创建和写入模式应该是cFile.Open( pFileName, CFile::modeRead)

Answer 5

str.Right(int n);你用错了吧！
从右边截取n个字符长度
