receiving the data from serial port and show a new screen (C# .net micro framework)

[zelov]

Hi,

I am creating an interface which contains the listbox(C# .net micro framework). When the listbox item is seletected, it will send a character to the serial port and show a "send command" screen. When receiving the data from serial port, it will show another "receive command" screen. The problem i am facing now is the program not able to show out the "receive command" screen. The following is some part of the code:

public class MainMenu : PresentationWin dow
{
public MainMenu(myAppl ication app)
: base(app)
{
System.Threadin g.Thread serialThread = new
System.Threadin g.Thread(update Data);
serialThread.St art();
// do something here
}

public void updateData()
{
while (true)
{
importData();
}
}

int bytecount = 0;

public int importData()
{
UTF8Encoding enc = new UTF8Encoding();
byte[] buffer = new byte[32];
count = serialPort.Read (buffer, 0, buffer.Length, 1000);

int count;
if (count > 0)
{
serialPort.Writ e(buffer, 0, count);
bytecount += count;
new WarningScreen(m yApp);
}
return byteCount.ToStr ing();
}
}

public class WarningScreen : PresentationWin dow
{
public WarningScreen(m yApplication app)
: base(app)
{
// do something here...
}
}

I think maybe is because the while loop part cause the problem, but i don't
have any idea to solve it. Is there anyone can help me?

Thanks,
Celine
