vb.net按键代码 vbnet button

VB.net 怎么制作按键连发功能用API函数,以下代码Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As LongPrivate Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As LongPrivate Const WS_EX_LAYERED = H80000
Private Const GWL_EXSTYLE = (-20)
Private Const LWA_ALPHA = H2
Private Const LWA_COLORKEY = H1Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Const HWND_TOPMosT = -1
Private Const SWP_NOMOVE = H2
Private Const SWP_NosIZE = H1
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_KEYDOWN = H100
Const WM_KEYUP = H101
Const WM_CHAR = H102
Const VK_F1 = H70
Private Sub SendF1(hwnd)'调用这个过程即可对目标窗体发送F1键
Call PostMessage(hwnd, WM_KEYDOWN, VK_F1, 0)
Call PostMessage(hwnd, WM_KEYUP, VK_F1, 0)
End Sub这里是发送F1的实例 , 各个按键对应的虚拟键码,要到网上查
VB.NET添加按钮代码⒃谙允景磁サ氖录?刑砑?br /me.backgroundimage=system.drawing.bitmap.fromfile("vb.net按键代码你vb.net按键代码的图片文件路径")
命令按钮1.Visable=False'或者命令按钮1.Hide
命令按钮2.Visable=False'或者命令按钮2.Hide
在窗体vb.net按键代码的Click事件中添加
命令按钮1.Visable=True'或者命令按钮1.show
命令按钮2.Visable=True'或者命令按钮2.show
me.backgroundimage=nothing
在退出按钮vb.net按键代码的事件中添加
End
2、这里应该还有两个Timer,Timer1和Timer2
在开始按钮的事件中添加
timer1.interval=1000
Timer1.enable=True
timer2.interval=500
timer2.enable=true
在Timer1的Tick事件中添加
label1.text=timeofday
在Timer2的Tick事件中添加
label2.left=label2.left10
if label2.left

vb.netbutton改名由代码找到buttonvb.net教程之vb.net的Button控件
vb.net的Button控件
Button(按钮)控件一般接受鼠标单击事件被用来启动、中断或结束一个进程(相当于Visual Basic以前版本的CommandButton控件) 。单击Button控件时将调用已写入Click事件过程中的过程 。Button控件在大多数Visual Basic应用程序中都会用到vb.net按键代码,用户可以单击按钮执行操作 。单击时,按钮不仅能执行相应的操作,而且看起来与被按下和松开一样 。Button控件在工具箱中的图标如图所示vb.net按键代码:
