如何把文本框里输入的字符串转换为十六进制数啊？求高手指点
如题，因为最近在搞串口通信，涉及到很多类型的转换，比如把文本框里输入的PASSWORD转换为十六进制字符串，反过来又是怎样的呢？求指点。不甚感激~~

[解决办法]

C/C++ code

String AdressByteArrayToHexString(byte * address){   int length = sizeof(address) ;   String result = "";   for(int i = 0;i<length -1 ;  i++)   {      String temp;      temp.sprintf("%02X", address[i]);      result += temp;   }   return result.UpperCase();}void __fastcall TForm1::btn1Click(TObject *Sender){//这样更简洁:         AnsiString   Data   =   "020080A76354";        BYTE   bb[6];        BYTE   *p   =   (BYTE   *)Data.c_str();         for   (int   i   =   0;   i   <   6;   i++,   p   +=   2)        {                 sscanf(p,   "%02X ",   bb   +   i);         }        Caption = AdressByteArrayToHexString(bb);}
