user32.dll FindWindowEx получение текста

Как я могу получить текст с lable окна другой программы используя user32.dll? Пытаюсь найти но не получается.
int i = 0; void Button1Click(object sender, EventArgs e) {
var m = FindWindow("WindowsForms10.Window.8.app.0.33c0d9d", null); var child = FindWindowEx(m, IntPtr.Zero + i, null, null); textBox2.Text += i + GetWindowTextRaw(child); i++;
}
Вот что "говорит" Inspector по клику на lable:

Спустя несколько дней разобрался. Может кому пригодится.
void FindWindow(){ var hWndParent = FindWindow("WindowsForms10.Window.8.app.0.33c0d9d", null); FindChild(hWndParent); } void FindChild(IntPtr hWndParent){ EnumChildWindows(hWndParent, new EnumWindowsProc(( hWnd, lParam ) => { if (GetParent(hWnd) != hWndParent){ return true; } FindChild(hWnd); if(GetText(hWnd).StartsWith("1P11321126F1#2PG#")){ if(label1.InvokeRequired){ label1.Invoke(new MethodInvoker(delegate { label1.Text = GetText(hWnd).Trim();})); } } return true; }), IntPtr.Zero); } string GetText(IntPtr hWnd){ StringBuilder sb = new StringBuilder(WM_GETTEXTLENGTH + 100000); string text = SendMessage(hWnd, WM_GETTEXT, WM_GETTEXTLENGTH + 100000, sb).ToString(); return sb.ToString(); }
