VB 如何设置快捷键?

最简单的方法是按Ctrl+E打开菜单编辑器，然后设置个菜单项为退出什么的，设置其快捷键为Ctrl+D，勾选掉“可见”属性（如果是“不可见”属性请勾上）。然后运行就可以了。
还有的方法：（代码）
方法①：
Private
Sub
Form_KeyDown(KeyCode
As
Integer,
Shift
As
Integer)
Me.KeyPreview
=
True
If
KeyCode
=
vbKeyD
And
Shift
=
2
Then
End
End
Sub
方法②：
Private
Sub
Form_KeyUp(KeyCode
As
Integer,
Shift
As
Integer)
Me.KeyPreview
=
True
If
KeyCode
=
vbKeyD
And
Shift
=
2
Then
End
End
Sub
方法③：
Private
Sub
Form_KeyPress(KeyAscii
As
Integer)
If
KeyAscii
=
4
Then
End
End
Sub
方法①②③的灵敏度不一样，③里面的KeyAscii=4是Ctrl+D的Ascii值，是测试出来的。
至于Ascii值测试代码，只要将方法③的语句换为MsgBox
KeyAscii就行了

很简单，在窗体的keydown事件中写

===================================
keydown事件不可行，因为这是全局热键，给你一个完整的代码：

自己写的。。不过我的原程序比这个多了一个功能。。如果你想要的话，我传给你，留下邮箱

alt+f4
这个不用，默认系统就是用来关闭当前程序的~
private
sub
form_keydown(keycode
as
integer,
shift
as
integer)
if
keycode
=
vbkeyf1
then
image1_click
if
keycode
=

then
image2_click
。。。。
