上面写字符串。这里，读字符串。dll一样。    __int64 iFile;    int iFileLength;    iFile = FileOpen("a.exe",fmOpenRead);    iFileLength = FileSeek(iFile,0,2);    FileSeek(iFile,0,0);    FileSeek(iFile,iFileLength-12,0);    char buf[12];    FileRead(iFile,buf,12);    if(AnsiString(buf).Pos("你好")>0)MessageBox(this->Handle,"成功","提示",MB_ICONINFORMATION);esleMessageBox(this->Handle,"失败","提示",MB_ICONINFORMATION);
