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添加字符

有甚多办法，我说个最简单的

dim xstr as string = "abcde"

Xstr = "(" xstr ")"

VB.net中如何给字符串组赋值?

dim Userlist() as string

redim Userlist(10)

for i=0 to 10

userlist(i) = i

Next

这样就行

vb.net 实现ComboBox输入字符自动补充字符

Public Sub AutoComplete(ByVal cmb As ComboBox, ByVal e As System.Windows.Forms.KeyPressEventArgs)

If cmb.DataSource Is Nothing Then

Return

End If

If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Enter) Then

Return

End If

Dim strFindStr As String = ""

If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Back) Then

If (cmb.SelectionStart = cmb.Text.Length) Then

If cmb.Text.Length  0 Then

strFindStr = cmb.Text.Substring(0, cmb.Text.Length - 1)

End If

Else

If cmb.SelectionStart  0 Then

strFindStr = cmb.Text.Substring(0, cmb.SelectionStart - 1)

End If

End If

e.Handled = False

Else

If (cmb.SelectionLength = 0) Then

strFindStr = cmb.Text + e.KeyChar

Else

If (cmb.SelectionStart = cmb.Text.Length) Then

strFindStr = e.KeyChar

Else

If cmb.SelectionStart  0 Then

strFindStr = cmb.Text.Substring(0, cmb.SelectionStart - 1) + e.KeyChar

Else

strFindStr = e.KeyChar

End If

End If

End If

End If

Dim intIdx As Integer = -1

Dim dv As DataView

If TypeOf (cmb.DataSource) Is DataTable Then

dv = CType(cmb.DataSource, DataTable).DefaultView

End If

cmb.DataSource = dv

cmb.SelectedIndex = -1

cmb.Text = strFindStr

AutoComplete(sender, e)
