vbnet按键设置 vbnet button

IT技术快捷键

vb.net 如何实现自定义的快捷键及对应的文件保存用户的自定义设置一般可以存在app.config文件中
在程序开启后可以定义全局变量存储这些配置，这样就不必每次都读配置文件了
你可以在你的项目属性里面找到资源选项，里面可以直接添加静态的配置（此处添加的项会直接存储在app.config中)
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
如何用VB.NET设置菜单项的热键不清楚热键和快捷键是什么区别
1.如果你是指Chrl+S这样的快捷键，可以设置ShortCutKeys属性，属性窗口就有可视化编辑器 。
2.如果你是指"保存(S)"，其中s有下划线这样的用Alt+字母来访问的设置 ， 应该在菜单项的Text属性中使用符号 。符号后面的字母将被作为快速访问字符，显示的时候不会被显示出来，而字母会自动加上下划线 。比如"保存(s)" 。
3.和选中标记有关的属性有两个
CheckOnClick在菜单项上单击时是否改变Checked属性
Checked设置/获取 菜单项是否被选中
4.设置菜单项的Enabled属性为False
vb.net怎么设置快捷键新建一个Form1把Form1vbnet按键设置的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 = https://www.04ip.com/post/(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 = "vbnet按键设置我被局部快捷键给召唤vbnet按键设置了~"
End Sub
