[英]VBA interaction with internet explorer
我正在構建的宏從Excel電子表格中獲取名稱,打開Internet Explorer,然后搜索在線目錄。 在搜索目錄之后,它會提取一個包含管理器名稱的Java表單。 我可以手動選項卡到管理器名稱,右鍵單擊,復制快捷方式,然后將其發布回電子表格。 但是,我遇到了一致標簽和復制快捷方式的問題。
碼:
Sub Macro1()
'
Dim ie As Object
Set ie = CreateObject("internetexplorer.application")
ie.Visible = True
ie.navigate "****url****"
While ie.busy
DoEvents
Wend
ie.document.getElementById("SSOID").Value = "Z19516732"
ie.document.getElementById("Advanced").Checked = False
ie.document.all("Search").Click
'this loop is to slow the macro as the java form is filled from the search
For i = 1 To 400000000
i = i + 1
Next i
'ie.Object.Activate
ie.document.getElementById("Advanced").Checked = False
ie.document.getElementById("SSOID").Focus
Application.SendKeys "{TAB 6}" ', True
'bring up the control menu/right click
Application.SendKeys "+{F10}"
'copy shortcut is 8 items down on the list
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
Application.SendKeys "{DOWN}"
'enter was not working so the shortcut for the menu is 't'
'SendKeys "{ENTER}"
Application.SendKeys "{t}"
Windows("Book21").Activate
Range("A1").Select
ActiveSheet.Paste
End Sub
在你的模塊的開頭,把這行代碼:
Public Declare Function SetForegroundWindow Lib "user32" (ByVal HWND As Long) As Long
這稱為Declare Statement
,允許您訪問Windows內置的SetForegroundWindow
函數。 此函數位於Windows系統的user32
DLL中。 實際上,VBA可以通過這種方式訪問多個DLL中的許多其他函數(有關更多示例,請參閱鏈接)。
在你的代碼,而與你的IE對象交互,記錄HWND
( 句柄到窗口),如下所示:
Dim HWNDSrc As Long
HWNDSrc = ie.HWND
然后,在與Java交互之后,使用它繼續:
SetForegroundWindow HWNDSrc
這告訴Windows系統將HWND
標識的窗口設置為前景窗口(顧名思義)。
但是,這可能沒有必要,具體取決於您與IE的交互方式。 換句話說,如果您不需要查看/觸摸窗口,您仍然可以使用該代碼中的對象進行交互。
有一些方法可以使用GetElementById()
和GetElementsByTagName()
等代碼獲取您正在尋找的快捷方式( 有關詳細信息 , 請參閱此處 ),但這取決於如何創建源。 例如,如果你知道HTML源代碼,那么<a href="...>
鏈接應該相對容易拉動。
在第二次檢查您的代碼后,我注意到您使用循環來“減慢”宏。 我有一個功能,我一直使用自己的類似方法。 希望這有助於您完成所需的工作。 我已經從我原來的代碼中修改了我的代碼,因為我有其他細節不適用於您的情況。 如果有任何錯誤,我可以根據需要進行調整。
Public Sub WaitForIE(myIEwindow As InternetExplorer, HWND As Long, WaitTime As Integer)
' Add pauses/waits so that window action can actually
' begin AND finish before trying to read from myIEWindow.
' myIEWindow is the IE object currently in use
' HWND is the HWND for myIEWindow
' The above two variables are both used for redundancy/failsafe purposes.
' WaitTime is the amount of time (in seconds) to wait at each step below.
' This is variablized because some pages are known to take longer than
' others to load, and some pages with frames may be partially loaded,
' which can incorrectly return an READYSTATE_COMPLETE status, etc.
Dim OpenIETitle As SHDocVw.InternetExplorer
Application.Wait DateAdd("s", WaitTime, Now())
Do Until myIEwindow.ReadyState = READYSTATE_COMPLETE
' Wait until IE is done loading page and/or user actions are done.
Loop
Application.Wait DateAdd("s", WaitTime, Now())
While myIEwindow.Busy
DoEvents ' Wait until IE is done loading page and/or user actions are done.
Wend
On Error Resume Next
' Make sure our window still exists and was not closed for some reason...
For Each OpenIETitle In objShellWindows
If OpenIETitle.HWND = HWND Then
If Err.Number = 0 Then
Set myIEwindow = OpenIETitle
Exit For
Else
Err.Clear
End If
End If
Next OpenIETitle
On Error GoTo 0
End Sub
