Im useng visual basic to make a control program for a usb relay board
This is the c# code that i know works
private void button1_ON_Click(object sender, EventArgs e)
{
serialPort1.Write(new byte[] { 0xFF, 0x01, 0x01 }, 0, 3);
panel1.BackColor = Color.Lime;
}
or
VB 6
Private Sub cmdOn_Click()
With MSComm1
'make sure the serial port is open
If .PortOpen = False Then .PortOpen = True
'send the data
.Output = Chr$(255)
.Output = Chr$(1)
.Output = Chr$(1)
End With 'MSComm1
End Sub
Any ideas on how to get it to work for VB? I really dont want to rewrite the entire thing, any help much appicated.
