[解决办法]

C/C++ code

#include <stdio.h>void __fastcall TForm1::Button1Click(TObject *Sender){    char *s = "41424344";    char out[5]= {0};    for (int i = 0; i < 8; i+= 2)    {        sscanf(s + i, "%02x", &out[i / 2]);    }    ShowMessage(out);}

string areturn = "";

     while(sourestr.Length() >0)  
     {  
         BYTE it=StrToInt(sourestr.SubString(1,1))*16+StrToInt(sourestr.SubString(2,1));  
         areturn+= it
         sourestr=sourestr.SubString(3,sourestr.Length());  
     }

AnsiString s1="41424344";
AnsiString s2=IntToHex(StrToInt(s1),4);
ShowMessage(s2);
