VB.NET 向指定(網(wǎng)頁或軟件)的輸入框內(nèi)輸入字符,如何實(shí)現(xiàn)?

假如Form1有個(gè)TextBox1，雙擊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

原碼：

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

用vb.net怎么樣輸入密碼時(shí)顯示****

例如：TextBox控件，只要在屬性窗口將 PasswordChar 設(shè)置為你想要顯示的符號即可。如“*”、“？”等

vb.net如何在文本框里輸入字符，已經(jīng)綁定數(shù)據(jù)源的Listbox里面就自動跳轉(zhuǎn)到該條目

Private Sub Text1_Change()

For x = 0 To List1.ListCount - 1

If Text1.Text = List1.List(x) Then

List1.Selected(x) = True

End If

Next x

End Sub
