[C++] 批量删除文件名多余的一个相同字符串

使用C++方法：

// ++++++++

#include <string>
#include <io.h>
#include <iostream>

{
continue;
}
//cout<<file.name<<endl;

{

}

int ilen = file_name.length();

if(access_rs == 0)
//if ((fopen(path_new.c_str(),"r"))!=0)
{
cout<<"Files has existed!"<<path_new.c_str()<<endl;
}
else
{
rename(path_old.c_str(),path_new.c_str());
}
}
}
else
{
cout<<"Not find any file!"<<endl;
}
}
}
_findclose(lf);
//cin.get();
return true;
}

void OnBnClickedButton1()
{

}

在VS2010上面测试没问题
