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
方法一:
Clipboard.SetText "123321"
Shell "notepad.exe /c "
方法二:
a = Shell("notepad.exe", vbNormalFocus)
AppActivate a
SendKeys "123321", True

Private Sub SendBlogTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SendBlogTimer.Tick
Dim textboxUserId As HtmlElement
Dim textboxPassword As HtmlElement
Dim buttonSubmit As HtmlElement
textboxUserId = SendBlogBrowser.Document.All("username")'获取用户名输入框
textboxPassword = SendBlogBrowser.Document.All("password")'获取密码输入框
buttonSubmit = SendBlogBrowser.Document.All("btnLogin")'获取登陆按钮
textboxUserId.SetAttribute("value","用户名")'给用户名输入框赋值
textboxPassword.SetAttribute("value","密码")'给密码框赋值
buttonSubmit.InvokeMember("click")’执行登陆按钮的单击
End Sub
其中的SendBlogBrowser为WebBrowser控件
