Question

我遇到了这个问题。

我有一个页面，我需要上传文件。当我点击“浏览器”时，会打开“选择要上传的文件”窗口，我需要选择（双击）TXT文件。

我尝试使用Set fd = Application.FileDialog（msoFileDialogFilePicker），但无法识别此对象。

任何帮助将不胜感激！

    Sub Main
    ' Get the browser object belonging to the active/topmost IE tab
    Dim objIe
    Dim activeDocument
    Dim Button
    Set activeDocument = Nothing


    ' Try and get the window object of the active IE tab
    Set objIe = GetActiveBrowserObj 'this is a function previously defined that allows me to work on the active browser window
        If objIe Is Nothing Then
          MsgBox "Could not get active IE document object”
          Exit Sub
        End If

    ' Assign the document object to the activeDocument variable
    Set activeDocument = objIe.Document
        If activeDocument Is Nothing Then
          MsgBox "Could not get active IE document object"
          Exit Sub
        End If
    'Click the browse button to upload the first TXT file
    Set Button = objIe.Document.getElementById("txtfile1")
        Button.Click

    chooseFile()

End Sub

Private Sub chooseFile()

    Dim fd
    Dim strTxt As String

    Start:
    'Set fd = Application.FileDialog(msoFileDialogFilePicker)
    With fd
       .Title = "Choose File to Upload" 'Change the title to suit
       .Filters.Add "txt files", "*.txt", 1 'Change the filters to suit, or omit for none
       .AllowMultiSelect = False
       If .Show = -1 Then
           'The user made a selection.  The variable strWorkBook will contain the path\name of the file
           strTxt = .SelectedItems(1)
       Else
           response = MsgBox("You have not selected a txt file")
           If response = vbRetry Then
               GoTo Start
           Else
               Exit Sub
           End If
       End If
    End With
    Set fd = Nothing
End Sub

您必须使用API与该窗口进行互动，方法是找到名称为“选择要上传的文件”的窗口

这是一个例子

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Sub Sample()
    Dim Ret

    Ret = FindWindow(vbNullString, "Choose File To Upload")

    If Ret <> 0 Then
        MsgBox "File upload window Found"
    Else
        MsgBox "File upload window Not Found"
    End If
End Sub

一旦锁定了RELavnt窗口，就必须找到Handle的{{1}}，然后在那里粘贴您的文件名。完成后，您会找到Textbox按钮的句柄，最后单击它。

我已广泛报道here。虽然在我在链接中发布的示例中，我使用Open保存文件，但您必须使用相同的方法来查找句柄并上传文件。
