請問各位大大,要如何在VBA的環境中使用SendMessage或PostMessage來對"檔案下載"對話盒進行操作?
如網址 http://www.twse.com.tw/ch/trading/fund/BFI82U/BFI82U_print.php?begin_date=20120611&end_date=&report_type=day&language=ch&save=csv
以下是我使用過的方法,但依舊無法成功- Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
- Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
- Private Declare Function PostMessage& Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any)
- Private Declare Function SetForegroundWindow Lib "user32" (ByVal hwnd As Long) As Long
- Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
- Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)
- Private Const WM_LBUTTONDOWN = &H201
- Private Const WM_LBUTTONUP = &H202
- Private Const BM_CLICK = &HF5
- Private Const MOUSEEVENTF_LEFTDOWN = &H2
- Private Const MOUSEEVENTF_LEFTUP = &H4
- Sub test()
- Dim IE As Object
- Dim hpwnd As Long, hcwnd As Long
- Dim iRet As Long
-
- Set IE = CreateObject("InternetExplorer.Application") '設定InternetExplorer物件
-
- strLink = "http://www.twse.com.tw/ch/trading/fund/BFI82U/BFI82U_print.php?begin_date=20120611&end_date=&report_type=day&language=ch&save=csv" '檔案下載網址
-
-
- With IE
- .Visible = True '開啟IE
- .Navigate strLink '連結網址
- End With
-
-
- Do
- hpwnd = FindWindow("#32770", "檔案下載") '抓取對話盒的handle
- DoEvents
- Loop While hpwnd = 0
-
- Do
- hcwnd = FindWindowEx(hpwnd, 0, "Button", "儲存(&S)") '抓取對話盒按鈕的handle
- DoEvents
- Loop While hcwnd = 0
- iRet = SetForegroundWindow(hcwnd) '設定焦點
- '在以下五種方法經皆由windows發送訊息模仿滑鼠按鍵,,依然無法請問各位是否有其他方法可以做到windows發送訊息模仿滑鼠按鍵
- '方法一
- iRet = SendMessage(hcwnd, BM_CLICK, 0, 0) '透過windows發送訊息模仿滑鼠按鍵
- '方法二
- 'iRet = SendMessage(hcwnd, WM_LBUTTONDOWN, 0, 0) '滑鼠左鍵按下
- 'iRet = SendMessage(hcwnd, WM_LBUTTONUP, 0, 0) '滑鼠左鍵釋放
- '方法三
- 'PostMessage hcwnd, WM_LBUTTONDOWN, 0&, CLng(&H90009) '滑鼠左鍵按下
- 'PostMessage hcwnd, WM_LBUTTONUP, 0&, CLng(&H90009) '滑鼠左鍵釋放
- 'PostMessage hcwnd, WM_LBUTTONDOWN, 0&, CLng(&H90009) '滑鼠左鍵按下
- 'PostMessage hcwnd, WM_LBUTTONUP, 0&, CLng(&H90009) '滑鼠左鍵釋放
- '方法四
- 'mouse_event MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0 '透過滑鼠事件, 滑鼠左鍵按下
- 'mouse_event MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 '透過滑鼠事件, 滑鼠左鍵釋放
-
- '方法五
- 'SendKeys "%s", True '透過按下Alt + s 儲存檔案
- Set IE = Nothing '釋放資源
- End Sub
