嘿，我想弄清楚如何一直走到它说的地方：

窗口 00211286 "" QWidget

在此处输入图像描述

以绿色突出显示的是我试图用下面的代码找到的内容：

在此处输入图像描述 目前我有这个：

Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Declare Function FindWindowEx Lib "user32.dll" Alias "FindWindowExA" (ByVal hWndParent As IntPtr, ByVal hWndChildAfter As Integer, ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As IntPtr) As IntPtr
Private Declare Function PostMessage Lib "user32.dll" Alias "PostMessageA" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As IntPtr) As IntPtr
Public Declare Function SendMessageLong& Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long)

Public Const WM_CHAR = &H102
Private Const BM_CLICK = &HF5
Public Const WM_LBUTTONDBLCLK = &H203
Public Const ENTER_KEY = 13

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim hwndParent As Long = FindWindow(vbNullString, "Genymotion")
    Dim hwndButton As Long = FindWindowEx(hwndParent, IntPtr.Zero, "QWidget", "")
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "content")
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "mainFrame")
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "")
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "qt_scrollarea_viewport")
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "")
End Sub

我得到了 FindWindow 的值，然后也得到了第一个 findwindowEx .... 但之后我得到了一个很大的 0。然后对于最后一个 FindWindowEx，我得到的数字与我在第一个 findwindowEx 上的数字相同。

任何帮助都会很棒！

试试这个：

    Dim hwndParent As Long = FindWindow(vbNullString, "Genymotion") ' Parent Window by Caption
    Dim hwndButton As Long = FindWindowEx(hwndParent, IntPtr.Zero, "QWidget", "") ' First Child QWidget
    hwndButton = FindWindowEx(hwndParent, hwndButton, "QWidget", "") ' Second Child QWidget
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "content") ' "content" QWidget
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "mainFrame") ' "mainFrame" QWidget
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "") ' First Child QWidget
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "qt_scrollarea_viewport") ' "qt_scrollarea_viewport" QWidget
    hwndButton = FindWindowEx(hwndButton, IntPtr.Zero, "QWidget", "") ' First Child QWidget

注意这两行发生了什么：

    Dim hwndButton As Long = FindWindowEx(hwndParent, IntPtr.Zero, "QWidget", "") ' First Child QWidget
    hwndButton = FindWindowEx(hwndParent, hwndButton, "QWidget", "") ' Second Child QWidget

第一行获取第一个具有 001816EC 句柄的 QWidget。在第二行中，我们使用相同的父句柄，但我们将先前找到的小部件的句柄传递给名为“hWndChildAfter”的第二个参数。这将获得第二个具有 0011686A 句柄的 QWidget。这两个窗口是彼此的“兄弟姐妹”。
