【问题描述】：

继这部出色的作品之后，这里： Batch copy files to SharePoint site

我现在可以通过单击按钮将我的压缩文件上传到 Sharepoint。

我现在的问题是：如何删除使用相同方法上传的文件？

我稍微修改了代码以将不同的文件保存到不同的 SharePoint 文件夹。 示例如下：

 
Public Sub CopyToSharePoint()

Dim xmlhttp
Dim sharepointUrl
Dim sharepointFolder
Dim sharepointFileName
Dim LstrFileName, strFilePath, strMonthYear, PstrFullfileName, PstrTargetURL As String
Dim LlFileLength As Long
Dim Lvarbin() As Byte
Dim LvarBinData As Variant
Dim fso, LobjXML As Object
Set fso = CreateObject("Scripting.FileSystemObject")
Dim fldr As folder
Dim f As File

'Parent Sharepoint
sharepointUrl = "[SHAREPOINT PATH HERE]"

'Sets the Month%20Year
strMonthYear = Format(Now(), "mmmm yyyy") & "\"

'File Path
strFilePath = "[ARCHIVE DRIVE]" & strMonthYear

'Check to see if DRA for current month%20year exists
If Len(Dir(strFilePath, vbDirectory)) = 0 Then
    MkDir "strFilePath"
End If

Set LobjXML = CreateObject("Microsoft.XMLHTTP")

'Where we're uploading files from
Set fldr = fso.GetFolder(strFilePath)

For Each f In fldr.Files

If Format(f.DateCreated, "dd/mm/yyyy") = Format(Now(), "dd/mm/yyyy") Then

If InStr(1, f.Name, "[FILESTRING1]", vbTextCompare) > 0 Then
sharepointFolder = "[SHAREPOINTSTRING1]/"
    ElseIf InStr(1, f.Name, "[FILESTRING2]", vbTextCompare) > 0 Then
    sharepointFolder = "[SHAREPOINTSTRING2]"
        ElseIf InStr(1, f.Name, "[DONOTUPLOADTHISFILE]", vbTextCompare) > 0 Then
        GoTo NextF:
            Else
            sharepointFolder = "[SHAREPOINTMAINFOLDER]"
End If


sharepointFileName = sharepointUrl & sharepointFolder & f.Name

PstrFullfileName = strFilePath & f.Name
LlFileLength = FileLen(PstrFullfileName) - 1

' Read the file into a byte array.
ReDim Lvarbin(LlFileLength)
Open PstrFullfileName For Binary As #1
Get #1, , Lvarbin
Close #1

' Convert to variant to PUT.
LvarBinData = Lvarbin
PstrTargetURL = sharepointUrl & sharepointFolder & f.Name

' Put the data to the server, false means synchronous.
LobjXML.Open "PUT", PstrTargetURL, False


' Send the file in.
    LobjXML.Send LvarBinData

End If

NextF:
Next f

Set LobjXML = Nothing
  Set fso = Nothing

End Sub

【问题讨论】：

您是否已经尝试过 "LobjXML.Open "DELETE", PstrTargetURL, False" "LobjXML.Send Nothing" ？

是的，我做到了。抱歉没有添加。出现：运行时错误'-2147024809（80070057）'：参数不正确。

MSDN 示例在这里：msdn.microsoft.com/en-us/library/ie/ms535874(v=vs.85).aspx（对我的格式表示歉意）

【参考方案1】：

我没有关闭对服务器的请求，哦！ 在单独的实例中设置它为我解决了它。

我没有将文件名转换为二进制然后再转换为变体，只是将其保存为字符串。 您必须从 LastCoder 的示例中给出的最后一个 LobjXML.SEND 中省略 NOTHING。添加这个会重现我上面给出的运行时错误。

感谢 LastCoder 的帮助。 这是修改后的代码：

Public Sub DeleteFromSharePoint()

Dim xmlhttp
Dim sharepointUrl, sharepointFolder, sharepointFileName
Dim f, strZip As String
Dim LobjXML As Object

' Parent Sharepoint
sharepointUrl = "[SHAREPOINT URL]"

' In this test module, we're just deleting from the parent directory
sharepointFolder = ""

' Sets the report name we want to remove
f = "test"

' Sets the full .ZIP filename
' This is how reports are archived by date
strZip = f & "%20-%20" & Format(Now() - 1, "YYYY.MM.DD") & ".zip"

Set LobjXML = CreateObject("Microsoft.XMLHTTP")

    sharepointFileName = sharepointUrl & sharepointFolder & strZip

    ' Removes the data from the server, false means synchronous
    LobjXML.Open "DELETE", sharepointFileName, False

    ' Sends the request to remove the file
    LobjXML.Send

  Set LobjXML = Nothing

End Sub
