vb.nettxt无法输入

你是用输入法的吧，这个是.Net Framework的Bug吧，用输入法的步骤如下：

3、切换到自己要用的输入法

这样一般都可以了

VB.NET 向指定(网页或软件)的输入框内输入字符,如何实现?

假如Form1有个TextBox1，双击TextBox1填入123

Public Class Form1

Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Integer

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub TextBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.DoubleClick

System.Windows.Forms.SendKeys.Send("123")

End Sub

End Class

看你的VB.NET 版本了

用 My.Computer.Keyboard.SendKeys("123", True) 代替 System.Windows.Forms.SendKeys.Send("123") 也可以

原码：

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub TextBox1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.DoubleClick

My.Computer.Keyboard.SendKeys("123", True)

End Sub

End Class

VB.net 软键盘 制作

Public Class Form2

Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

AddHandler Label1.MouseEnter, AddressOf LabelMouseEnter

AddHandler Label2.MouseEnter, AddressOf LabelMouseEnter

AddHandler Label1.MouseLeave, AddressOf LabelMouseLeave

AddHandler Label2.MouseLeave, AddressOf LabelMouseLeave

AddHandler Label1.MouseDown, AddressOf LabelMouseDown

AddHandler Label2.MouseDown, AddressOf LabelMouseDown

End Sub

Private Sub LabelMouseEnter(ByVal sender As Object, ByVal e As System.EventArgs)

Dim c As Label = DirectCast(sender, Label)

c.BackColor = Color.DodgerBlue

End Sub

Private Sub LabelMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)

Dim c As Label = DirectCast(sender, Label)

Form1.TextBox1.Text = c.Text

End Sub

Private Sub LabelMouseLeave(ByVal sender As Object, ByVal e As System.EventArgs)

Dim c As Label = DirectCast(sender, Label)

c.BackColor = SystemColors.Control

End Sub

End Class

vb.net请教各位高手，谁有用VB.NET写输入法的实例?

输入法编程是件很繁锁的事情,

你可以在网上找找, 记得曾经我进入过, [输入法编程爱好者] 的一个论坛, 你找找看.
