For x = 0 To List1.ListCount - 1
If Text1.Text = List1.List(x) Then
List1.Selected(x) = True
End If
Next x
End Sub
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
有甚多办法,我说个最简单的
dim xstr as string = "abcde"
Xstr = "(" xstr ")"
dim Userlist() as string
redim Userlist(10)
for i=0 to 10
userlist(i) = i
Next
这样就行
