VB 从零开始编外挂(四)

--------------------------------------------------------------------------------------------------------------------------------------------------------
**添加快捷键
** --------------------------------------------------------------------------------------------------------------------------------------------------------
需要VB API函数：
GetAsyncKeyState **←判断函数调用时指定虚拟键的状态
** --------------------------------------------------------------------------------------------------------------------------------------------------------
相关API声明：
GetAsyncKeyState
↓
Private Declare Function GetAsyncKeyState Lib "user32" ( ByVal vkey As Long ) As Integer
Private Function MyHotKey(vKeyCode) As Boolean
--------------------------------------------------------------------------------------------------------------------------------------------------------
需要的控件： ** Timer（interval不为空）
** --------------------------------------------------------------------------------------------------------------------------------------------------------
代码：
Private Declare Function GetAsyncKeyState Lib "user32" ( ByVal vkey As Long ) As Integer
Private Function MyHotKey(vKeyCode) As Boolean
MyHotKey = (GetAsyncKeyState(vKeyCode) < 0)
End Function
'然后在循环中或Timer的Timer事件中检测:
Private Sub Timer1_Timer()
If MyHotKey(vbKeyA) And vbKeyControl Then 'ctrl+A
End '关闭
End If
'其中vbkeyA是键盘″A″的常数，其他键可按F1查得。
End Sub
--------------------------------------------------------------------------------------------------------------------------------------------------------
**其它方法：
** 比如按下"ctrl+A"就退出!
' 可以设置Form的KeyPreview属性为True，然后在Form_KeyDown事件中添加代码：
Private Sub Form_KeyDown(KeyCode As Integer , Shift As Integer )
If KeyCode = Asc("A") And Shift = vbCtrlMask Then unload me '如果ctrl+A键被按下就退出
End Sub
