I don't get any error or exception.

Button in one Window:

private void button1_Click(object sender, EventArgs e)
{
    ControlPort.Output(0x378, 0xff);
}

and inpout.dll interface:

class ControlPort
{
    [DllImport("inpout32.dll", EntryPoint = "Out32")]
    public static extern void Output(int adress, int value);
}

What is wrong? LED on D2 is on all the time.

I have Windows 7 x64 Ultimate.

Answer

For x64 you should use "InpOutx64.dll".
