拖入一个Button1到Form1上面

然后加入以下代码

Private

Sub

Form1_KeyDown(sender

As

Object,

e

As

KeyEventArgs)

Handles

Me.KeyDown

If

e.KeyData

=

(Keys.Alt

Or

Keys.G)

Then

Button1.PerformClick()

'或者用Button1_Click(Nothing,

New

EventArgs)

'快捷键Alt+G触发Button1_Click()事件。

End

If

End

Sub

Private

Sub

Button1_Click(sender

As

Object,

e

As

EventArgs)

Handles

Button1.Click

Button1.Size

=

New

23)

Button1.Text

vb.net,怎么做全局快捷键??

'vb全局快捷键是个大大滴难题,不好整。以下是个演示,办法比较笨,本人自用的,你试试。

'窗体放上控件:Command1、Label1、Check1、Check2、Text1、Text2、Timer1

'加入以下代码,运行,设置"确定"键的快捷键

'可选"CTRL+某键"或者"SHIFT+某键"

'"某键"自己设置,只能设置为字母或数字

Private Declare Function GetAsyncKeyState Lib "user32" _

(ByVal vKey As Long) As Integer 'API声明

Dim i

'================================================================

'这部分是设置各控件的大小、位置和初始属性,为了便于演示才加的,

'你可以自行设计好各控件的大小、位置和初始属性,无需这些代码。

Private Sub Form_Load()

Form1.Width = 2690: Form1.Height = 2100

Command1.Width = 1215: Command1.Height = 495

Command1.Top = 120: Command1.Left = 120

Command1.Caption = "确定"

Label1.Width = 2175: Label1.Height = 255

Label1.Top = 720: Label1.Left = 120

Label1.Caption = "设置 确定 键的快捷键:"

Check1.Width = 975: Check1.Height = 255

Check1.Top = 960: Check1.Left = 120

Check1.Caption = "CTRL +"

Check2.Width = 975: Check2.Height = 255

Check2.Top = 1320: Check2.Left = 120

Check2.Caption = "SHIFT +"

Text1.Width = 255: Text1.Height = 270

Text1.Top = 960: Text1.Left = 1080

Text1.Text = ""

Text2.Width = 255: Text2.Height = 270

Text2.Top = 1320: Text2.Left = 1080

Text2.Text = ""

Timer1.Interval = 10 'Timer的属性,必须设置

End Sub

Private Sub Timer1_Timer()

If Text1 "" Then

If Len(Text1) 1 Then Text1 = Left(Text1, 1)

Then Text1 = Chr(Asc(Text1) - 32)

Private Sub Command1_Click()

print "你好"

SendKeys "你好"

vb.net 全局热键

见下面的代码

Public Class Form1

Public Declare Auto Function RegisterHotKey Lib "user32.dll" Alias "RegisterHotKey" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Boolean

Public Declare Auto Function UnRegisterHotKey Lib "user32.dll" Alias "UnregisterHotKey" (ByVal hwnd As IntPtr, ByVal id As Integer) As Boolean

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

'注册全局热键 

RegisterHotKey(Handle, 0, 0, Keys.F4)

'第3个参数意义: 0=nothing 1 -alt 2-ctrl 3-ctrl+alt 4-shift 5-alt+shift 6-ctrl+shift 7-ctrl+shift+alt

End Sub

Private Sub Form1_Closed(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Closed

UnRegisterHotKey(Handle, 0)

End Sub

Protected Overrides Sub WndProc(ByRef m As Message)

If m.Msg = 786 Then

Me.Activate()

End If

MyBase.WndProc(m)

End Sub

End Class
