Download file with progress meter in VBA

I have done this using the wininet.dll functions. Unfortunately I cannot paste my code as it is owned by my employer.

Use InternetOpen and InternetOpenUrl to start the download, HttpQueryInfoLong to get the content length and then repeatedly call InternetReadFile to read data into a buffer (I use a 128k buffer), writing the data to a file and updating the progress bar as you go.

Declarations to get you started:

Private Declare Function InternetOpen Lib "wininet.dll" Alias "InternetOpenA" (ByVal sAgent As String, ByVal lAccessType As Long, ByVal sProxyName As String, ByVal sProxyBypass As String, ByVal lFlags As Long) As Long
Private Declare Function HttpQueryInfo Lib "wininet.dll" Alias "HttpQueryInfoA" (ByVal hHttpRequest As Long, ByVal lInfoLevel As Long, ByRef sBuffer As Any, ByRef lBufferLength As Long, ByRef lIndex As Long) As Long
Private Declare Function InternetCloseHandle Lib "wininet.dll" (ByVal hInet As Long) As Integer
Private Declare Function InternetReadFile Lib "wininet.dll" (ByVal hFile As Long, ByRef Buffer As Any, ByVal lNumberOfBytesToRead As Long, lNumberOfBytesRead As Long) As Integer
Private Declare Function InternetOpenUrl Lib "wininet.dll" Alias "InternetOpenUrlA" (ByVal hInternet As Long, ByVal lpszUrl As String, ByVal lpszHeaders As String, ByVal dwHeadersLength As Long, ByVal dwFlags As Long, ByVal dwContext As Long) As Long

Private Const INTERNET_OPEN_TYPE_PRECONFIG = 0
Private Const INTERNET_FLAG_RELOAD = &H80000000
Private Const INTERNET_FLAG_KEEP_CONNECTION = &H400000 ' use keep-alive semantics - required for NTLM proxy authentication
Private Const HTTP_QUERY_CONTENT_LENGTH = 5
Private Const HTTP_QUERY_FLAG_NUMBER = &H20000000
