Subject: Implementation of Win32Api with "WNetUseConnection"

Hi!

I am new on RUBY and I have difficulty with the Win32API call.


I receive thise message : "rb18.tmp:43:in `call': can't convert
NETRESSOURCE into Integer (TypeError)"

How I send a struture in the declaration of the API fouction? It is
not an Integer and not an String....
 Api_ConnectIPC  = Win32API.new( 'mpr', 'WNetUseConnection',
['P','P','P','P','P','P','P','P'], 'L'


That is my code :


require 'Win32API'


#DECLARATION DES CLASSES ET CONSTANTE
NO_ERROR = 0
CONNECT_LOCALDRIVE = 256
CONNECT_REDIRECT = 128
RESOURCE_GLOBALNET = '2'.hex
RESOURCETYPE_DISK = '1'.hex
RESOURCEDISPLAYTYPE_SHARE = '3'.hex
RESOURCEUSAGE_CONNECTABLE = '1'.hex
CONNECT_UPDATE_PROFILE = 1

class NETRESSOURCE
 
attr_accessor :dwScope, :dwType, :dwDisplayType, :dwUsage, :pLocalName, :pRemoteName, :pComment, :pProvider
    def initialize
	@dwScope = @dwType = @dwDisplayType = @dwUsage = @pLocalName=
@pRemoteName = @pComment = @pProvider  = ""
    end
end


#ICI Je déclare mon API qui deviens un Objet
Api_ConnectIPC  = Win32API.new( 'mpr', 'WNetUseConnection',
['P','P','P','P','P','P','P','P'], 'L' )



#Ici je déclare une fonction qui va utilisé l'Objet
def Connect_to_server(server, user, password)
	serveur_cible = NETRESSOURCE.new
	serveur_cible.dwScope = RESOURCE_GLOBALNET
	serveur_cible.dwType = RESOURCETYPE_DISK
	serveur_cible.dwDisplayType = RESOURCEDISPLAYTYPE_SHARE
	serveur_cible.dwUsage = RESOURCEUSAGE_CONNECTABLE
	serveur_cible.pLocalName = nil
	serveur_cible.pRemoteName = server
    lpResult = nil

	hwndOwner = ""
    dwFlags = CONNECT_REDIRECT
    lpAccessName = " " * 32
    lpBufferSize = lpAccessName.length

	rep = Api_ConnectIPC.call(hwndOwner, serveur_cible, user, password,
dwFlags, lpAccessName, lpBufferSize, lpResult )
end


And I receive this message : /rb18.tmp:43:in `call': can't convert
NETRESSOURCE into Integer (TypeError)


Thanks for your help
