WNetUseConnection And FTP?

[rorubin]

Hi,

I have seen some commercial products that allow you to map an ftp site to a Drive letter, and have decided to take a go at it. (I want to be able to use in my code.) Anyway I have code that works great for UNC paths can anyone give me some information, help, ideas anything that would lead me to getting this to work with an FTP site. Also if I am completely on the wrong track, I would appreciate it if you would let me know. The code I am working from is from the Microsoft Web Site and it is the following:


Option Explicit

' CONSTANTS
Private Const NO_ERROR = 0
Private Const CONNECT_LOCALDRIVE = 256
Private Const CONNECT_REDIRECT = 128
Private Const RESOURCE_GLOBALNET = &H2
Private Const RESOURCETYPE_DISK = &H1
Private Const RESOURCEDISPLAYTYPE_SHARE = &H3
Private Const RESOURCEUSAGE_CONNECTABLE = &H1
Private Const CONNECT_UPDATE_PROFILE = 1

' LOCAL VARIABLES
Private MappedDrive As String

' CUSTOM TYPES
Private Type NETRESOURCE
dwScope As Long
dwType As Long
dwDisplayType As Long
dwUsage As Long
lpLocalName As String
lpRemoteName As String
lpComment As String
lpProvider As String
End Type

' API DECLARATIONS
Private Declare Function WNetUseConnection Lib "mpr.dll" _
Alias "WNetUseConnectionA" ( _
ByVal hwndOwner As Long, _
ByRef lpNetResource As NETRESOURCE, _
ByVal lpUsername As String, _
ByVal lpPassword As String, _
ByVal dwFlags As Long, _

As Long

Private Declare Function WNetCancelConnection2 Lib "mpr.dll" _
Alias "WNetCancelConnection2A" ( _
ByVal lpName As String, _
ByVal dwFlags As Long, _
ByVal fForce As Long) _
As Long

Private Sub Command1_Click()
Dim NetR As NETRESOURCE ' NetResouce structure
Dim ErrInfo As Long ' Return value from API
Dim buffer As String ' Drive letter assigned to resource
Dim bufferlen As Long ' Size of the buffer
Dim success As Long ' Additional info about API call

' Initialize the NetResouce structure
NetR.dwScope = RESOURCE_GLOBALNET
NetR.dwType = RESOURCETYPE_DISK
NetR.dwDisplayType = RESOURCEDISPLAYTYPE_SHARE
NetR.dwUsage = RESOURCEUSAGE_CONNECTABLE
NetR.lpLocalName = vbNullString
NetR.lpRemoteName = txtUNC.Text

' Initialize the return buffer and buffer size
buffer = Space(32)
bufferlen = Len(buffer)

' Call API to map the drive
ErrInfo = WNetUseConnection(Me.hWnd, NetR, txtPWD.Text, txtUser.Text, _
CONNECT_REDIRECT, buffer, bufferlen, success)

' Check if call to API failed. According to the MSDN help, there
' are some versions of the operating system that expect the userid
' as the 3rd parameter and the password as the 4th, while other
' versions of the operating system have them in reverse order, so
' if first call to API fails, try reversing these two parameters.
If ErrInfo <> NO_ERROR Then
' Call API with userid and password switched
ErrInfo = WNetUseConnection(Me.hWnd, NetR, txtUser.Text, _
txtPWD.Text, CONNECT_REDIRECT, buffer, bufferlen, success)
End If

' Check for success
If (ErrInfo = NO_ERROR) And (success = CONNECT_LOCALDRIVE) Then
' Store the mapped drive letter for later usage
MappedDrive = Left$(buffer, InStr(1, buffer, &quot;:&quot)

' Display the mapped drive letter
MsgBox &quot;Connect Succeeded to &quot; & MappedDrive
Else
MsgBox &quot;ERROR: &quot; & Str(ErrInfo) & &quot; - Connect Failed!&quot;
End If
End Sub

Private Sub Command2_Click()
Dim ErrInfo As Long ' Return value from API

' Call API to disconnect the drive
ErrInfo = WNetCancelConnection2(MappedDrive, _
CONNECT_UPDATE_PROFILE, False)

' Check for success
If ErrInfo = NO_ERROR Then
MsgBox &quot;Disconnect of '&quot; & MappedDrive & &quot;' Succeeded&quot;

' Clear the mapped drive letter
MappedDrive = &quot;&quot;
Else
MsgBox &quot;ERROR: &quot; & Str(ErrInfo) & &quot; - Disconnect Failed!&quot;
End If
End Sub

Again Thanks

Here is a quick way to map a FTP. Write a something.bat file to look like this.

net use l: /delete
net use l: \\sla\sys access /user:mr
l:
cd\sla\coz
copy *.* d:\ftproot\coznet use l: /delete

' Not use the /delete if you don't want to disconnect.

The command &quot;net use l:&quot; assign the drive l: to the path of
\\sla\sys access, and the /user:mr is the login

Then just shell out to the something.bat

Hope this helps

Not exactly what i am looking for. This still uses a unc path. What i want is to map i: to let's say ftp.microsoft.com.
