Hola, como puedo hacer para conocer los valores de los datos de una  GUID (por ejemplo GUID_DEVINTERFACE_PARTITION) para luego ser usados con las APIS SetupDiGetClassDevs,  SetupDiEnumDeviceInterfaces, etc, etc. :

Identificador
GUID_DEVINTERFACE_PARTITION

Clase GUID

Que lástima.. No ???

Una boludez, pero a veces puede servir, con este code se puede saber la ruta (Path) del ejetutable al  que pertenece a una ventana, solo hay que pasar el puntero del mouse sobre la ventana que se quiere "investigar".

Ich muß den freien Raum einer Teilung wissen(kennen), es ist wichtig, dass die Teilung es Geheimnis (zu wissen, hat Brief(Buchstaben)) nicht, oder dass mit der API GetDiskFreeSpaceEx ich nicht, keiner mit WMI (Win32_LogicalDisk-FreeSpace) konnte, da die obengenannte erwähnte Teilung als eine logische Teilung nicht genommen wird, um Brief(Buchstaben) nicht zu haben. 

PD: WMI auch, seit dieser für einen Manager bestimmten Anwendung.(ADM)

Hola, hace unos dias que estoy buscando pero no le encuentro la vuelta, necesito saber el espacio libre (u ocupado) de una particion, es importante saber que la particion está oculta (no tiene letra) o sea que con la API GetDiskFreeSpaceEx no pude, tampoco con WMI (Win32_LogicalDisk-FreeSpace) ya que dicha particion no
es tomada como particion logica por no tener letra.

PD: WMI tambien me sirviria ya que la aplicacion esta destinada a un administrador.

Hola, dejo un ejemplo de como mandar una variable por memoria desde una aplicacion a otra y viceversa. Uso SendMessage con SETTEXT para enviar y SendMessage con GETTEXT para recibir.
Hay que compilar los dos Proyectos (Proyecto1 y Proyecto2) y luego ejecutar Proyecto1.

Este es un simple ejemplo de como interceptar Clcks en botones de una aplicación externa, en este caso la calculadora de windows XP (en vista y seven hay que cambiar las clases) usando la constante BM_GETSTATE para SendMessage cuyo valor de retorno es de 512 si el button recibe un click, retorno de 620 si el button tiene el foco y retono 0 si no tiene foco, son retornos "especiales" para la calculadora ya que los retornos de casi todos los button de otras aplicaciones son de 44 si reciben el click o de 108 si el click se provoca con la barra espaciadora. se pueden saber los retornos con:

MsgBox SendMessage(Hndl, BM_GETSTATE, 0, 0) 

otras constantes para aprovechar

Private Const BM_GETSTATE = &HF2
Private Const WM_SETFOCUS = &H7
Private Const WM_KILLFOCUS = &H8
Private Const WM_ENABLE = &HA

Termino de bajar la version Beta 1 del windows7 (en ingles), me pareció otra version del "vista" con menos requerimientos de harware, bueno, lo primero que hice fue probar algunas Apis (funcionaron todas las que usé) y lo segundo instalar VB6 Studio, me tiró un par de carteles  sobre Setup.exe y Acmboot.exe (mi ingles es limitado) pero se instaló completa y a primera "vista" funciona.

las version 32 bits (x86) y la version 64 bits (x64) se pueden bajar desde:

http://www.mundowindows.com/

como es obvio, son imagenes iso para dvd de 2.43 GB y 3.15 GB


PD1: segun la informacion que tengo Microsoft limitará a 2.500.000 las activaciones de esta version, el que lo quiera, a apurarse


PD2: Tal vez el mensaje no se encuadre totalmente el este foro pero quize compartir la información con la gente del foro donde participo.

[Nota1: Hay que compilar y guardar para ejecutarlo]

Con este código intento cerrar todas Aplicaciones (no procesos) con ventanas (visibles con y sin bordes) que se encuentran abiertas, con el Api SendMesssage (que me permite guardar los cambios) o con Taskkill (que cierra todo sin pedir permiso, ignorando todos los cambios), por lo tanto no se olviden de guardar todo antes de aplicar con Taskkill.

La pregunta es como puedo evitar que se cierre el explorer cuando tengo que cerrar las pantallas sin bordes, para no tener que ejecutarlo de nuevo al final ?,

If Check1.Value = 1 Then
  Dim x As Long: x = GetTickCount: While GetTickCount < x + 500: Wend

End If
End Sub


No doy con la clase del explorer para poder agregarla al if de EnumWindowsProc 

Public Function EnumWindowsProc(ByVal Hwnd As Long, ByVal lParam As Long) As Boolean
  If TaskWindow(Hwnd) Then
    If GetClsName(Hwnd) <> "Shell_TrayWnd" or GetClsName(Hwnd) <> "Classe_explorer" Then

No hay mucho que agregar, solo hace falta el nombre del ejecutable del proceso y para el que no sepa reestablecer el explorer luego de ejecutar el code del ejemplo (desaparecen los iconos, barra de inicio, menús de contexto, Etc, Etc) lo haga desde CTL-ALT-SUP (Aministrador, aplicaciones, tarea neva..., explorer, aceptar)

Private Sub Form_Load()
Shell "cmd.exe /c Taskkill /f /IM " + "EXPLORER.EXE"

PD: para enumerar los procesos que esten corriendo "WMI" o "API EnumProcesses"

[Para que funcione hay que compilar el proyecto, y ejucutar el exe creado.]

Hola, con este code Trato de evitar que cierren mi aplicacion  o un proceso "X" desde el Administrador de tareas de XP, en el Timer1 busco el HWn del"SyslistView32" de  procesos en el administrador, luego con la funcion "GetItemSelected" busco el numero de item que el usuario intenta seleccionar, con este item y la funcion "ListViewGetText" obtengo el string del item que se seleccionó, si este string es igual al nombre de mi aplicación (en este caso App.EXEName + ".exe" o EXPLORER.EXE) automaticamente con la funcion SelectedItem selecciono el item siguiente , pero solo cuando el usuario selecciona mi aplicación o el proceso que no se quiera cerrar.

If t = App.EXEName + ".exe" Then Call SelectedItem(Handle, x)
If t = "EXPLORER.EXE" Then Call SelectedItem(Handle, x)

Para que funcione hay que compilar el proyecto, y ejucutar el exe creado.

Por último lo probé en windows Xp (pro) , seria bueno probarlo en otros windows.

Function GetItemSelected(hwnd As Long) As Long
Dim i As Long, Index As Long
For i = 1 To GetListViewCount(hwnd)
Index = SendMessage(hwnd, LVM_GETITEMSTATE, i - 1, ByVal LVIS_SELECTED)
If Index > 0 Then
GetItemSelected = i
Exit For
End If
Next
End Function




PD 1: Las Funciones "GetItemSelected" y "ListViewGetText" me las pasó Leandro hace unos meses.

PD 2: Si el code le sirve a alguien y lo podemos mejorar seria buenisimo, y si no sirve lo descartamos

EDITADO 09/12/2008

PD 3: A continuación dejo el código original del formulario que publiqué en este mensaje, mantengo este code (que modifiqué mas arriba) porque las respuestas de Seba123neo y de Leandro que siguen a continuación se refieren a este code, pero repito el que vale es el code del formulario que está mas arriba
