Hi guys, I'm trying to link a Micro-controller board to my C++ program to control the relays on it. The vendor provided a test software in VB that involved entering the COM port number (4 in my case) and clicking a button to sync up with it, the full software and info on the board is here: [
http://www.oceancontrols.com.au/KTA-223.html] under the link 'VB6 test software' link. I've tried converting the code to C++ along with using namespaces, etc, but I seem to have hit some problems. The code is pretty long so I'll post the relevant things and the errors.
namespaces being used

using namespace System;
using namespace System::ComponentModel::Container;
using namespace System::ComponentModel;
using namespace System::Windows;
using namespace System::Windows::Forms;

Component Initialisation from VB changed to C++

public ref class zebra
{
public:
void InitializeComponent()
{
int components = gcnew System.ComponentModel.Container();
System.ComponentModel.ComponentResourceManager ^resources = gcnew System.ComponentModel.ComponentResourceManager(CzebraDlg.typeid);
int SerialPort1 = gcnew System.IO.Ports.SerialPort(this->components);
}
}
internal:
{
array<System.IO.Ports.SerialPort^> ^SerialPort1 = gcnew array<System.IO.Ports.SerialPort^>(this->components + 1);
};

For this part, I keep getting errors like
'error C2882: 'System' : illegal use of namespace identifier in expression'
and
'error C2228: left of '.ComponentModel' must have class/struct/union along with others.
I suspect I may gave failed to include something or that my syntax symbols and function calls are in error.
Lastly, the button that reads the COM port number from a text box to sync with the device (code below).

void CzebraDlg::OnBnClickedButton5()
{
try
{
if (SerialPort1::IsOpen)
{
SerialPort1->Close();
}
SerialPort1->PortName = "COM" + IDC_EDIT2->Text;
SerialPort1->Open();
}
catch (Exception ^ex)
{
CerrorDlg cid; //*** Create an instance of our dialog
cid.DoModal(); //Display Dialog box
}
}

For the button control, I get errors like
error C2227: left of '->Close' must point to class/struct/union/generic type
error C2227: left of '->PortName' must point to class/struct/union/generic type
and others all dealing with the '->' symbols.
I'm not really sure what the compiler is telling me but I suspect it is just a few lines I may not have. Can anyone help? The VB code I derived it from is from the link above. Thanks a lot in advance!! I'm using MFC to build the GUI.
