vbnet按键设置 vbnet输入输出方法

vb.net 平面按钮

本来有个属性FlatStyle设置为Popup基本上能实现这个情况，怎奈有个线框怎么也弄不掉。FlatAppearance.BorderSize设置为0不起作用，只对Flat有用，所以用代码在Flat和Popup两种风格之间切换。

'在鼠标进入时设置为浮雕风格

Private Sub Button1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseEnter

Button1.FlatStyle = FlatStyle.Popup

End Sub

'离开时设置为平面风格，这样像标签一样只剩下文字，当然要FlatAppearance.BorderSize设置为0

Private Sub Button1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseLeave

Button1.FlatStyle = FlatStyle.Flat

End Sub

'另外把UseVisualStyleBackColor 设置为 False也会好看一点。

请问VB.net中该如何设置按键输入与Button有相同的作用？

这个好办！！在form1 keydown事件中输入if e.keycode=keys.F1 then

加语句即可!!

vb.net怎么设置快捷键

新建一个Form1把Form1的KeyPreview改成True

拖入一个Button1到Form1上面

然后加入以下代码

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)

'快捷键Alt+G触发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 = "我被局部快捷键给召唤了~"

End Sub

vb.net 如何添加菜单快捷键

ToolStripMenuItem.ShortcutKeys 属性

获取或设置与 ToolStripMenuItem 关联的快捷键。

使用 ShortcutKeys 属性可以将组合键分配给菜单命令，例如，将 Ctrl+C 分配给“复制”命令。 您可以使用快捷键而不使用访问键，也可以同时使用快捷键和访问键，访问键是菜单或菜单项中与 Alt 键一起使用的带下划线的字母。 通过在要用于访问键的字母前面键入一个“and”符 ()，可以在代码中定义访问键。

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
