Question

VB全局快捷键问题

问下全局的快捷键
就是无论任何情况下按F10
就等于按了程序某个按钮的功能
还有一键呼出功能如何实现

Answer 1

呵呵

楼上俩位的，你们那个太占资源了，只有在没有办法的情况下才使用你们这个办法....

使用timer....如果使用这个功能，cup占用可不是一般的多阿~是非常多~

给你这个代码，只有在按下键盘的时候才会激发~不占资源~~

其实很简单的

Answer 4

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer

Private Sub Timer1_Timer()
If GetAsyncKeyState(vbkeyf10) < 0 Then XXX_click()
if .....其他键的... 呼出功能就是 form.show...其他自己发挥想象把..
End Sub

timer1.Interval = 1-100最好..不然会有点迟钝的..

Answer 5

请先定义一个模块，在模块中可以用Global完成你所说的全局快捷键。
