vb.net打开软件并输入账号密码登录

你可以使用以下代码来打开软件并自动输入账号密码登录：

'引用 Windows API
Imports System.Runtime.InteropServices

Public Class Form1
    '定义 API 函数
    Private Declare Auto Function FindWindow Lib "user32.dll" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
    Private Declare Auto Function SendMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer

    '定义常量
    Private Const WM_SETTEXT As Integer = &HC
    Private Const WM_KEYDOWN As Integer = &H100
    Private Const VK_RETURN As Integer = &HD

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        '打开软件
        Process.Start("C:\Program Files\YourSoftware\YourSoftware.exe")
        '等待软件启动
        Threading.Thread.Sleep(5000)
        '查找窗口
        Dim hWnd As IntPtr = FindWindow(Nothing, "YourSoftwareTitle")
        If hWnd <> IntPtr.Zero Then
            '输入账号
            SendMessage(hWnd, WM_SETTEXT, 0, "YourAccount")
            '输入密码
            SendMessage(hWnd, WM_SETTEXT, 0, "YourPassword")
            '按下回车键登录
            SendMessage(hWnd, WM_KEYDOWN, VK_RETURN, 0)
        End If
    End Sub
End Class

在代码中，你需要将 `YourSoftware` 替换为你要打开的软件的安装路径，将 `YourSoftwareTitle` 替换为你要打开的软件的窗口标题，将 `YourAccount` 替换为你的账号，将 `YourPassword` 替换为你的密码。
