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如何在文本框里输入字符，已经绑定数据源的Listbox里面就自动跳转到该条目Private Sub Text1_Change()
For x = 0 To List1.ListCount - 1
If Text1.Text = List1.List(x) Then
List1.Selected(x) = True
【vb.net输入符号 vb输入代码】End If
Next x
End Sub
用vb.net怎么样输入密码时显示****例如：TextBox控件，只要在属性窗口将 PasswordChar 设置为你想要显示的符号即可 。如“*”、“？”等
