URLDownloadToCacheFile

Hi,

When I use URLDownloadToCacheFile in my VB Code, I receive the following error:

DLL-Entry Point URLDownloadToCacheFile in URLMON.dll not found

My system is Windows 2000 Professional. urlmon.dll is very likely the most recent version, since it just got updated during a Windows Update (got the same error before the update).
Version Number: 6.0.2800.1400

To make things more confusing: URLDownloadToFile works without a problem, EVEN when I UNREGISTER c:\winnt\system32\urlmon.dll ! How is that possible?

Thanks for your help.

Well, URLDownloadToFile works, but URLDownloadToCacheFile doesn´t.

Code:

Private Declare Sub URLDownloadToCacheFile Lib "URLMON.dll" ( _
    ByVal lpunknown As Long, _
    ByVal lpcstr As String, _
    ByVal lptstr As String, _
    ByVal dword As Long, _
    ByVal dword As Long, _
    ByRef TLPBINDSTATUSCALLBACK As Long)
   
Private Sub Test()
   Dim url As String
   Dim localFileName As String
   
   On Error GoTo trackError
   
   url = "http://www.google.com/images/logo.gif"
     
   localFileName = Space(255)
   
   URLDownloadToCacheFile 0, url, localFileName, Len(localFileName), 0, 0
     
trackError:

Debug.Print Err.Description

End Sub

Found the solution to my problem. Have to use an alias in the API declaration. This works:

Private Declare Function URLDownloadToCacheFile Lib "urlmon" Alias "URLDownloadToCacheFileA" ( _
   ByVal lpUnkcaller As Long, _
   ByVal szURL As String, _
   ByVal szFileName As String, _
   ByVal dwBufLength As Long, _
   ByVal dwReserved As Long, _
   ByVal IBindStatusCallback As Long) As Long
