請問各位大大!!我從RS232 接收到資料,顯示出來是ASCII碼,請問怎麼把它轉成10進制??
以下是我的程式碼 感謝各位幫忙!!


void __fastcall TForm1::Button1Click(TObject *Sender)
{
char *ComNo;
DCB dcb;
String Temp;
//取得想要開啟的port
Temp = "COM" IntToStr(RadioGroup1->ItemIndex 1);
//轉換成指標形態
ComNo = Temp.c_str();
hComm = CreateFile(ComNo,GENERIC_READ | GENERIC_WRITE,
0, NULL, OPEN_EXISTING, 0, 0);
if (hComm == INVALID_HANDLE_VALUE) //if COM 未開啟
{
MessageBox(0, "開啟port error!!","Comm Error",MB_OK);
return;
}
//will dcb address 傳入取得通訊參數
GetCommState(hComm,&dcb); //得知目前COM狀態
dcb.BaudRate = CBR_9600; //set BaudRate 9600;
dcb.ByteSize = 8;
dcb.Parity = NOPARITY;
dcb.StopBits = ONESTOPBIT;
if(!SetCommState(hComm, &dcb)) //set COM state
{
MessageBox(0, "port set error!!","set error",MB_OK);
CloseHandle(hComm);
return;
}
Timer1->Enabled = True;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
String Temp;
char inbuff[1024];
DWORD nBytesRead, dwEvent, dwError;
COMSTAT cs;
//取得state
ClearCommError(hComm,&dwError,&cs);
// 資料是否大於buffer
if(cs.cbInQue > sizeof(inbuff))
{
PurgeComm(hComm, PURGE_RXCLEAR); //clear COM data
return;
}
ReadFile(hComm, inbuff,cs.cbInQue,&nBytesRead,NULL);//接收COM data
inbuff[cs.cbInQue] = '\0'; //轉移資料到變數中
Memo1->Text =Memo1->Text inbuff;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Button2Click(TObject *Sender)
{
if (hComm!=INVALID_HANDLE_VALUE) CloseHandle(hComm);
exit(EXIT_SUCCESS);
}

int n;
n=atoi(inbuff);
printf("string = %s integer = %d\n", inbuff, n);
