Private Const LWA_ALPHA = H2

Private Const LWA_COLORKEY = H1Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Const WM_KEYDOWN = H100

Const WM_KEYUP = H101

Const WM_CHAR = H102

Const VK_F1 = H70

Private Sub SendF1(hwnd) '调用这个过程即可对目标窗体发送F1键

Call PostMessage(hwnd, WM_KEYDOWN, VK_F1, 0)

Call PostMessage(hwnd, WM_KEYUP, VK_F1, 0)

End Sub这里是发送F1的实例，各个按键对应的虚拟键码，要到网上查

vb.net中，如何通过键盘上的按键触发button _click事件

1、将窗口的KeyPreview属性设置为True

Me.KeyPreview = True

2、处理窗口的KeyDown事件

Sub MainFormKeyDown(sender As Object, e As KeyEventArgs)

Select Case e.KeyCode

Case Keys.Escape

Me.button1.PerformClick

Case Keys.Enter

Me.button2.PerformClick

End Select

End Sub

VB.NET添加快捷键

你是要在程序里面按q相当于单击按钮

还是焦点不在程序里面的时候任意按q实现这个功能？

要是前者的话楼上的已经正解

要是后者的话需要全局钩子实现
