SerialPort.Write Method

$0sir,$0 $0this is my sample program written in c++ (Visual Studio 2008 IDE). My problem is that there is no error in the code but there is problem with the command passed. It is not passed as integer but as string. so the irobo could not recognize the command.$0 $0can you suggest me some alternatives or correction in my code.$0 $0$0 $0 $0/* the code follows*/$0 $0$0 $0 $0//This example implements serial communication$0 $0//with an arduino microcontroller on COM4 and the$0 $0//Picasso robot on COM5, your ports will vary:$0 $0//#include<stdafx.h>$0 $0#include <stdio.h>$0 $0#include<stdlib.h>$0 $0#using <System.dll>$0 $0using namespace System;$0 $0using namespace System::IO::Ports;$0 $0$0 $0 $0SerialPort^ OpenSerialPort(System::String ^port, int baud);$0 $0void CloseSerialPorts(SerialPort ^Port);$0 $0void TurnOnRobotServos(SerialPort ^RBPort);$0 $0$0 $0 $0SerialPort^ OpenSerialPort(System::String ^port, int baud)$0 $0{$0 $0SerialPort^ newport;$0 $0try$0 $0{$0 $0newport = gcnew SerialPort(port, baud);$0 $0newport->Open();$0 $0}$0 $0    catch (IO::IOException^ e  )$0 $0{$0 $0Console::WriteLine(e->GetType()->Name+": Port is not ready");$0 $0}$0 $0catch (ArgumentException^ e)$0 $0{$0 $0Console::WriteLine(e->GetType()->Name+": incorrect port name syntax, must start with COM/com");$0 $0}$0 $0return newport;$0 $0}$0 $0$0 $0 $0void TurnOnRobotServos(SerialPort ^RBPort)$0 $0{$0 $0char* msg="128 132 137 0 100 128 0";$0 $0$0 $0RBPort->Write(msg.toString());$0 $0}$0 $0$0 $0 $0void CloseSerialPorts(SerialPort ^Port)$0 $0{$0 $0Port->Close();$0 $0}$0 $0$0 $0 $0int main(array<System::String ^> ^args)$0 $0{$0 $0SerialPort^ Robot;$0 $0System::String^ RBPort = "COM1";$0 $0int RBbaud = 57600;$0 $0int ardbaud = 57600;$0 $0printf("done");$0 $0Robot = OpenSerialPort(RBPort,RBbaud);$0 $0TurnOnRobotServos(Robot);$0 $0$0 $0$0 $0$0 $0//CloseSerialPorts(ard);$0 $0CloseSerialPorts(Robot);$0 $0printf("exit");$0 $0while(1);$0 $0return 0;$0 $0}$0 $0$0 $0 $0Thanks in advance$0
