最小化，当检测keypression托盘图标 [英] detect keypression when minimized and trayicon

问题描述

有关我的测试，我在C＃中创建了一个小程序，以检测与此代码按键：

For my test I've created a little program in C# to detect key presses with this code:

protected override void OnKeyDown(KeyEventArgs e)
{
    if (e.KeyCode == Keys.F12)  MessageBox.Show("f12 pressed");
}

在表单集中和主动这工作得很好。我花了很多时间去寻找如何最小化时设置它的作品，我发现了一个解决方案，这里添加系统托盘图标。我也跟着解决方案，但没有工作了。

This works fine when the form is focused and active. I've spent many time to find how to set it for works when minimized, I found a solution here to add system tray icon. I followed solution but didn't work anymore.

当我将其最小化，图标托盘显示和工作，但我没有检测到按键。

When i minimize it, the icon tray appears and works, but i didn't detect key presses.

推荐答案

您的形式将只接收按键事件，当它具有焦点，接受你需要注册一个全局热键其他按键事件。

Your form will only receive keypress events when it has focus, to receive other keypress events you would need to register a global hotkey.
