这个程序主要是利用GetAsyncKeyState函数, NSxDCTw
使用GetAsyncKeyState可以获得键盘的动作。 alq>|,\x GetAsyncKeyState函数根据虚拟键表判断按键的类型。 q k !Q2W 返回值为一个16位的二进值数,如果被按下则最高位为1, l lQ<x 即返回-32767。下面是API函数及鼠标中左右键在虚拟键表中的定义: F35e/YfG Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer h5Z%|J>;0 好了,函数就先介绍这么多,下面开始动手实战了 DB?[h<^m first,当然是创建窗口了 ]A_)&`"Cb (+9@j( 2Qn%p[#n 在时间控件的Timer时间中定义检查按键类型,代码如下: &<L+;k~P% Dim AddKey M T{^=F ] KeyResult = GetAsyncKeyState(13) '回车键 H1q>UU: If KeyResult = -32767 Then or(Z-8a_ AddKey = "[ENTER]" br0gB3 r GoTo KeyFound YRB,jwne End If z<)?8tAgq KeyResult = GetAsyncKeyState(17) 'Ctrl键 }n8,Ga% If KeyResult = -32767 Then '?q|7[SU AddKey = "[CTRL]" u0N1+-6kr+ GoTo KeyFound 'os-+m@ End If YsDn?pD@ KeyResult = GetAsyncKeyState(8) '退格键 ZJd1Lx If KeyResult = -32767 Then M)Y`u AddKey = "[BKSPACE]" Y]ZOvA5W GoTo KeyFound 0gxbo End If -<qci3Ba} aQkgkV;~ KeyResult = GetAsyncKeyState(9) :fo%)_Jc!
