Recorre todos los controles de "X" tipo en un container.

Código
  1. #Region " Disable Controls "
  2.  
  3.    ' [ Disable Controls ]
  4.    '
  5.    ' // By Elektro H@cker
  6.    '
  7.    ' Examples:
  8.    '
  9.    ' Disable_Controls(Of CheckBox)(Me.Controls, False)
  10.    ' Disable_Controls(Of Button)(GroupBox1.Controls, False)
  11.  
  12.    Public Sub Disable_Controls(Of T As Control)(ByVal Container As Object, ByVal Enabled As Boolean)
  13.        For Each control As T In Container : control.Enabled = Enabled : Next
  14.    End Sub
  15.  
  16. #End Region





Pequeño ejemplo de como saber el tipo de objeto:

Código
  1. MsgBox(TypeName(Me))      ' Result: Form1
  2. MsgBox(TypeName(Me.Text)) ' Result: String
  3. MsgBox(TypeName(Panel1))  ' Result: Panel

Hide-Restore Process

Para ocultar o reestablecer la visibilidad de un proceso,
Esto solo oculta la ventana del proceso, no lo oculta del administrador de tareas,
la función "Restore" no está muy pulida, para perfeccionarlo habría que guardar cada handle de los procesos escondidos en un tipo de diccionario si se quiere usar con más de un proceso simultáneamente, ya que cuando ocultas una ventana, el handle se vuelve "0".

EDITO: Código mejorado:

· Ocultar uno o varios procesos en el Task Manager (Si, en el administrador de tareas!)

(Este código es originálmente de un anónimo (La class "TMListViewDelete", no sé ni me voy a molestar en buscar el nombre del autor), modificado por Kub0x, y vuelto a modificar por mí.)

-> http://foro.elhacker.net/net/aporte_ocultar_aplicacion_en_administrador_de_tareas-t359259.0.html

· Añadida compatibilidad para Windows en el lenguaje Inglés y Alemán, y con posibilidad de añadir fácilmente más soporte para otros lenguajes.

· Ahora se puede ocultar varios procesos al mismo tiempo.

· Añadida opción para poder especificar el/los proceso(s) que queremos ocultar.

· Añadida opción para controlar el intervalo de tiempo en el que se procesa la lista del TaskManager (Por defecto 3 ms, para evitar efectos visuales sospechosos en el TaskManager).

· Reorganización de la estructura del código original (Contenía demasiadas regiones para mi gusto y me dificultaba la lectura).

NOTAS: Si se ocultan varios procesos al mismo tiempo, aunque se use 1 ms para el intervalo del timer puede dar esos efectos visuales extraños en la lista del task manager, así que no excederse si se requiere perfección xD.

Lo he testeado en:
Código:
WinXP x86 Inglés
WinXP x86 Español
Win7 x86 Inglés
Win7 x64 Español
Win7 x64 Inglés
Win7 x64 Español

En Windows 8 No funciona.
A menos que se utilice el replacamiento NO oficial del TaskManager por el TaskManager de Windows 7 (como hago yo) porque el TaskManager de windows 8 no me gusta)


Ejemplos de uso:

Código
  1. Hide_Process_From_TaskManager.Processes_Names = _
  2. {Process.GetCurrentProcess.ProcessName, "cmd", "notepad.exe"} ' Processes to hide.
  3.  
  4. Hide_Process_From_TaskManager.Task_Manager_Window_Titles = _
  5. {"Administrador de tareas de Windows", "Windows Task Manager"} ' Support for unknown TaskManager Window Titles.
  6.  
  7. Hide_Process_From_TaskManager.Hide_Interval = 3 ' Hidding Interval.
  8.  
  9. Hide_Process_From_TaskManager.Running = True ' Start hidding processes.
  10.  
  11. Hide_Process_From_TaskManager.Running = False ' Stop hidding processes.

Los créditos son por orden para el creador de la Class TMListViewDelete que ronda por internet,
luego para las modificaciones de Kub0x y por tener la generosidad de haber compartido el código,
y por último para mis modificaciones y compartirlo con vosotros.    :)

Es anónimo xq me da la gana xD, vi el code del TMListViewDelete posteado por un "guiri" hace mucho tiempo (código que solo funcionaba en XP), lo cierto es que ví la Class en varios sitios buscando una manera de ocultar procesos en el TaskManager, pero no recuerdo el autor, y Kub0x no lo nombra en su code tampoco, así que... anonymous!
