How can I mapp a network drive using Delphi

function NetUse(LokaleRessource,RemoteRessource: String) : Integer;
{ This routine allows you to connect a network drive.
  Example: NetUse(U:,\\GENTKBF1\SYS connects the local drive u: with the network
  volume SYS from server \\GENTKBF1
  Possible returne values are:

  Value                         Meaning
  ERROR_ACCESS_DENIED         Access is denied.
  ERROR_ALREADY_ASSIGNED The device specified in the lpLocalName parameter is already connected.
  ERROR_BAD_DEV_TYPE         The device type and the resource type do not match.
  ERROR_BAD_DEVICE         The value specified in lpLocalName is invalid.
  ERROR_BAD_NET_NAME         The value specified in the lpRemoteName parameter is not valid or cannot be located.
  ERROR_BAD_PROFILE         The user profile is in an incorrect format.
  ERROR_CANNOT_OPEN_PROFILE The system is unable to open the user profile to process persistent connections.
  ERROR_DEVICE_ALREADY_REMEMBERED An entry for the device specified in lpLocalName is already in the user profile.
  ERROR_EXTENDED_ERROR         A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
  ERROR_INVALID_PASSWORD The specified password is invalid.

  ERROR_NO_NETWORK         The network is not present.

begin
  Result:= WNetAddConnection(PChar(RemoteRessource),Nil,PChar(LokaleRessource));
end;

function NetUseDelete(LokaleRessource: String) : Integer;
{ This function coses an existing networc connection.
  Example: the function call NetUseDelete('O:') cancels the connection from
  drive O: to the actually used network recource.
