I've tried almost everything to Invoke that API and I always failed... I suceed with InternetOpen/InternetOpelUrl/InternetCloseHandle but not that one :/ Private Declare Function InternetReadFile Lib "wininet.dll" (ByVal hFile As Long, ByVal lpBuffer As String, ByVal dwNumberOfBytesToRead As Long, lNumberOfBytesRead As Long) As Integer
bDoLoop = InternetReadFile(hInternetOpen, strArray, Len(strArray), lNumberOfBytes) Can anyone help please?
