How to put this to .NET code?

VB Code:

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
Public Function DownloadFile(URL As String, LocalFilename As String) As Boolean
Dim lngRetVal As Long
lngRetVal = URLDownloadToFile(0, URL, LocalFilename, 0, 0)
If lngRetVal = 0 Then DownloadFile = True
End Function
Private Sub Form_Load()
DownloadFile "http://www.allapi.net", "c:\allapi.htm"
End Sub

how do i put this to .NET code? i already tryed but it seems to take no effect :(

The problem is just that in .net the long data type has changed. If you want that api call to work just replace where you have used long to use integer. However, you should use the framework classes instead. To achieve the same function just use
Dim downloadfile As New System.Net.WebClient()
downloadfile.DownloadFile ("http://www.allapi.net", "C:\allapi.htm")

ah...i mistaken the API ..there was an API around that if u put the download file it would call that IE prompt message if u want to save the file bla bla bla...is that function that i am looking around...anyone know what is it?
