C＃LPT inpout32.dll [英] C# LPT inpout32.dll

问题描述

我没有得到任何错误或异常。

按钮在一个窗口：

 私人无效的button1_Click（对象发件人，EventArgs的）
{
    ControlPort.Output（的0x378，为0xFF）;
}
 

和inpout.dll接口：

 类ControlPort
{
    [的DllImport（inpout32.dll，入口点=Out32）]
    公共静态外部无效输出（INT联系地址，int值）;
}
 

什么是错的？ D2上的LED是在所有的时间。

我的Windows 7 64位旗舰版。

解决方案

对于x64你应该使用InpOutx64.dll。

请访问：<一href="http://www.highrez.co.uk/Downloads/InpOut32/default.htm">http://www.highrez.co.uk/Downloads/InpOut32/default.htm 在那里，你可以阅读更多，找到样本。

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.

解决方案

For x64 you should use "InpOutx64.dll".
