Download a text file using HTTP
Can anyone give me an EXAMPLE of how to download a text file from a server onto the local machine without any user interaction (ie no prompts to run from current location or save).
Ie the answer I am looking for is a complete version of the following
Public Function GetFile(byval sURL as string, byval sFileName as string) as Boolean
'Download and store file at sURL as sFilename
'Return True/False based on success of operation
End Function
I have seen a very similar question posted here before but the accepted answer wasnt a complete solution and I cant get it to work.
Anybody able to provide me with a complete example in the format above ?
Cheers

are you partial against using the inet control?
ASKER
Nope... thats fine.
well you can stick an inet control on your form and try this:
Dim b() As Byte
Dim intCount As Integer
Dim strData As String
Inet1.Cancel ' Stops any current operations
b() = Inet1.OpenURL("http://www.vbsquare.com/index.html", icByteArray)
For intCount = 0 To UBound(b) - 1
strData = strData & Chr(b(intCount))
Next intCount
Open "myfile.txt" For Binary Access Write As #1
Put #1, , b()
Close #1
Dim b() As Byte
Dim intCount As Integer
Dim strData As String
Inet1.Cancel ' Stops any current operations
b() = Inet1.OpenURL("http://www.vbsquare.com/index.html", icByteArray)
For intCount = 0 To UBound(b) - 1
strData = strData & Chr(b(intCount))
Next intCount
Open "myfile.txt" For Binary Access Write As #1
Put #1, , b()
Close #1

Hi
What do you meen "Text File?" Page?
Add Internet Transfer Control(Inet1) at your form
Private Function GetPage(sURL As String, sFile As String) As Boolean
Dim nFile As Integer
GetPage = True
On Error GoTo ERROR_GetPage
Dim b() As Byte
Inet1.Cancel
Inet1.Protocol = icHTTP
Inet1.URL = sURL
b() = Inet1.OpenURL(, icByteArray)
nFile = FreeFile
Open sFile For Binary Access Write As nFile
Put nFile, , b()
Close nFile
EXIT_GetPage:
Exit Function
ERROR_GetPage:
Select Case MsgBox("Error " & Err.Number & ": " & Err.Description & " at line: " & Erl, vbAbortRetryIgnore + vbCritical, "Error")
Case vbAbort
Screen.MousePointer = vbDefault
GetPage = False
Resume EXIT_GetPage:
Case vbRetry
Resume
Case vbIgnore
GetPage = False
Resume Next
End Select
Resume EXIT_GetPage
End Function

Not a problem....the more the merrier for those who need answers =)

Thanks AzraSound... thats pretty much what I needed. Only two minor problems :
a) Unfortunately it puts quotes around the data in the file but thats not a big issue.
b) It seems to be cacheing the file somewhere : The situation is I'm writing a vb front end to a web-based system (I'm writing both sides of the equation), and when I modify the text file on my web site I still seem to be getting the file I first downloaded.
Any ideas (not to worry if you havent - you have already answered my real question).
