В качестве альтернативы, UIAutomationCOM объект может быть использован:
Sub GetFilesAutomation()
Dim o As IUIAutomation
Dim e As IUIAutomationElement
Dim SaveAsHwnd As LongPtr
Dim ie As New InternetExplorer
Set o = New CUIAutomation
ie.Navigate "http://daccess-ods.un.org/access.nsf/Get?Open&DS=A/HRC/WGAD/2015/28&Lang=E"
ie.Visible = True
Sleep 10000
ie.ExecWB 4, 1
Sleep 5000
SaveAsHwnd = FindWindow(vbNullString, "Save As")
Set e = o.ElementFromHandle(ByVal SaveAsHwnd)
Dim iCnd As IUIAutomationCondition
Set iCnd = o.CreatePropertyCondition(UIA_NamePropertyId, "Save")
Dim Button As IUIAutomationElement
Set Button = e.FindFirst(TreeScope_Subtree, iCnd)
Dim InvokePattern As IUIAutomationInvokePattern
Set InvokePattern = Button.GetCurrentPattern(UIA_InvokePatternId)
InvokePattern.Invoke
End Sub
Вы, очевидно, дали хороший ответ, который решает проблему. Но только одно: вы говорите, что 'mech-> get ($ link)' не будет работать без полного URL-адреса. Это неверно. Я могу получить относительные ссылки с 'get'. – CJ7
Извините. Я не знаю, почему я так думал. Я, должно быть, сделал еще одну ошибку. Я обновлю ответ. Вы можете использовать '-> follow_link' или' -> get' по своему усмотрению. Если вы используете '-> get', вы можете отправить объект WWW :: Mechanize :: Link. – bolav
