了解橙色按钮的摩托罗拉MC65状态 [英] Knowing the state of orange button in motorola MC65

问题描述

我需要能够知道什么是橙色按钮的当前状态，并得到通知，如果这种状态已经改变摩托罗拉设备MC65。 可悲的是我不能使用Symbol.Keyboard.KeyPad类，因为它不支持MC65

I need to be able to know what is the current state of orange button and be notified if this state has changed on Motorola device MC65. Sadly I can't use Symbol.Keyboard.KeyPad class since it is not supported on MC65

推荐答案

在docos状态：

键盘支持的功能 - 只有以下两个API的是   在MC65支持。

Keyboard Supported feature - Only the following two API’s are supported on MC65.

Symbol.Keyboard.KeyPad.SetKeyState。   Symbol.Keyboard.KeyPad.GetKeyStateEx。

Symbol.Keyboard.KeyPad.SetKeyState. Symbol.Keyboard.KeyPad.GetKeyStateEx.

以下键不MC65支持。 KEYSTATE_ALT，KEYSTATE_CTRL，   KEYSTATE_NUMLOCK，KEYSTATE_NUMERIC_LOCK，KEYSTATE_CAPSLOCK

Following keys are not supported in MC65. KEYSTATE_ALT, KEYSTATE_CTRL, KEYSTATE_NUMLOCK, KEYSTATE_NUMERIC_LOCK, KEYSTATE_CAPSLOCK

有关的MC65，微软API，不能用于获取橙键   状态。 的Symbol.Keyboard.KeyPad类提供了一个新的   GetKeyStateEx（）函数来获取改性剂的当前状态   键。参考API函数的页为这个API的说明。

For the MC65, Microsoft APIs cannot be used to get the Orange key states. The Symbol.Keyboard.KeyPad class provides a new GetKeyStateEx() function to get the current state of the modifier keys. Refer to the API function’s page for a description of this API.

和它有这个code样品：<​​/ P>

And it has this code sample:

// Get the key states
int keyState = keypad.GetKeyStateEx();

bool lockedState = false;

// Checking for a lock state first as it cannot be combined with others
switch (keyState)
{
    case KeyStates.KEYSTATE_ORANGE_SHIFT_LOCK:
        checkBoxOrangeShiftLock.Checked = true;
        lockedState = true;
        break;
    case KeyStates.KEYSTATE_FUNCTION_LOCK:
        checkBoxFuncLock.Checked = true;
        lockedState = true;
        break;
    case KeyStates.KEYSTATE_ORANGE_LOCK:
        checkBoxOrangeLock.Checked = true;
        lockedState = true;
        break;
    case KeyStates.KEYSTATE_NUMERIC_LOCK:
        checkBoxNumLock.Checked = true;
        lockedState = true;
        break;
    case KeyStates.KEYSTATE_SHIFT_LOCK:
        checkBoxShiftLock.Checked = true;
        lockedState = true;
        break;
    default:
        break;
}

if (lockedState)
{
    // No need to continue if a locked state
    this.Update();
    return;
}

// Process unlock or temp lock states if any
this.checkBoxUnShift.Checked = (keyState & KeyStates.KEYSTATE_UNSHIFT) != 0;
this.checkBoxShift.Checked = (keyState & KeyStates.KEYSTATE_SHIFT) != 0;
this.checkBoxCtrl.Checked  = (keyState & KeyStates.KEYSTATE_CTRL) != 0;
this.checkBoxAlt.Checked    = (keyState & KeyStates.KEYSTATE_ALT) != 0;
this.checkBoxNum.Checked = (keyState & KeyStates.KEYSTATE_NUMLOCK) != 0;
this.checkBoxCaps.Checked = (keyState & KeyStates.KEYSTATE_CAPSLOCK) != 0;
this.checkBoxFunc.Checked = (keyState & KeyStates.KEYSTATE_FUNC) != 0;
this.checkBoxOrangeTemp.Checked = (keyState & KeyStates.KEYSTATE_ORANGE_TEMP) != 0;
