How to download a file from Sharepoint with VBA

问题:

I am trying to download a file from Sharepoint with VBA and can not figure out how to do it! The file is actually a picture (not sure if that matters?) and the download goes fine, but the picture isn't view-able once it gets onto the system. (Code below) I'm thinking that I'm downloading it in the wrong format, but (like I said) I can't figure it out.

Sub DownloadFromSharepoint()
    Dim myURL As String
    myURL = "https://MYSHAREPOINTSITE"

    Dim WinHttpReq As Object
    Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")
    WinHttpReq.Open "GET", myURL, False
    WinHttpReq.Send

    If WinHttpReq.Status = 200 Then
        Set oStream = CreateObject("ADODB.Stream")
        oStream.Open
        oStream.Type = 1
        oStream.Write WinHttpReq.ResponseBody
        oStream.SaveToFile ("C:\Users\DOMAIN\temp.jpg")
        oStream.Close
    End If
End Sub

Here is the wrapper code I currently use to download files from our Sharepoint site:

Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" (ByVal pCaller As Long, _
    ByVal szURL As String, ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long

Function DownloadFileFromWeb(strURL As String, strSavePath As String) As Long
    ' strSavePath includes filename
    DownloadFileFromWeb = URLDownloadToFile(0, strURL, strSavePath, 0, 0)
End Function

The function DownloadFileFromWeb returns 0 if the download was successful.
