Question

vb.net,怎么做全局快捷键？？

Answer 1

'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
