vc中，如何判断键盘没有按键按下？

[hzsszmy]

在c中，这个很好办，察看bioskey即可，

但是在vc中，如何判断键盘没有按键按下？

[qhplqhp2004]

BOOL CExeSecond::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if (pMsg->message==WM_KEYDOWN)//键盘按下,!= 没按下就相反
{
//处理函数
}

return CDialog::PreTranslateMessage(pMsg);
}

[Snovate]

先在类向导里加：PreTranslateMessage
pMsg->message==WM_KeyDown就行了

WM_KEYDOWN 和 WM_SYSKEYDOWN都要判断

[hzsszmy]

我希望在onMouseMove(...)函数中，检测检测键盘状态，码将安出？

[Snovate]

onMouseMove？那就在onMouseDown里设一个标志位改变其值，然后在onMouseMove里判别就OK了吧

[xladykiller]

那就要onMouseMove中判断WM_KEYDOWN 和 WM_SYSKEYDOWN
不过如果你的mouse不动得时候，就不会进行判断

SHORT GetKeyState(int nVirtKey);

Parameters

nVirtKey
[in] Specifies a virtual key. If the desired virtual key is a letter or digit (A through Z, a through z, or 0 through 9), nVirtKey must be set to the ASCII value of that character. For other keys, it must be a virtual-key code. 
If a non-English keyboard layout is used, virtual keys with values in the range ASCII A through Z and 0 through 9 are used to specify most of the character keys. For example, for the German keyboard layout, the virtual key of value ASCII O (0x4F) refers to the "o" key, whereas VK_OEM_1 refers to the "o with umlaut" key.

Return Value

The return value specifies the status of the specified virtual key, as follows: 

If the high-order bit is 1, the key is down; otherwise, it is up.
If the low-order bit is 1, the key is toggled. A key, such as the CAPS LOCK key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0. A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off when the key is untoggled.
