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
