拖入一個(gè)Button1到Form1上面

然后加入以下代碼

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)

'快捷鍵Alt+G觸發(fā)Button1_Click()事件。

End

If

End

Sub

Private

Sub

Button1_Click(sender

As

Object,

e

As

EventArgs)

Handles

Button1.Click

Button1.Size

=

New

Size(180,

23)

Button1.Text

=

"我被局部快捷鍵給召喚了~"

End

Sub

vb.net,怎么做全局快捷鍵？？

'vb全局快捷鍵是個(gè)大大滴難題，不好整。以下是個(gè)演示，辦法比較笨，本人自用的，你試試。

'窗體放上控件：Command1、Label1、Check1、Check2、Text1、Text2、Timer1

'加入以下代碼，運(yùn)行，設(shè)置"確定"鍵的快捷鍵

'可選"CTRL+某鍵"或者"SHIFT+某鍵"

'"某鍵"自己設(shè)置，只能設(shè)置為字母或數(shù)字

(ByVal vKey As Long) As Integer 'API聲明

Dim i

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

'這部分是設(shè)置各控件的大小、位置和初始屬性，為了便于演示才加的，

'你可以自行設(shè)計(jì)好各控件的大小、位置和初始屬性，無需這些代碼。
