Otra duda con registros...

[ToNy_EsP]

Hola a todos, pues me gustaría saber qué código poner para por ejemplo, explico:

Tenemos un form con 1 checkbox (checkbox1) con el Value = 0, abrimos el form1 y marcamos el Checkbox (value = 1) y cierras el programa. Bien, lo que quiero hacer es guardar en el registro o en algún lado de alguna manera, hacer que cuando el checkbox este marcado y se cierra el programa, al abrirse el programa aparezca el checkbox marcado, y si abres de nuevo el programa y desclickas el checkbox (value = 0) y cierras el programa, que al abrirlo de nuevo aparezca el checkbox1 desclickado.

Yo más o menos tengo una idea, pero no sé construir el código :S, más que nada porque no llevo mucho en VB.

Un saludo y gracias de antemano a toda la comunidad ElHacker

un archivo de configuración.ini seria lo mejor

Gracias por tu respuesta  pero es que el código no lo entiendo :S, nunca he controlado archivos .INI con VB.

Podrias explicarlo un poco por favor?

Gracias de antemano!!

Algunas api's que puedes utilizar para el manejo de .ini son:
GetPrivateProfileString
WriteProfileString
WritePrivateProfileString
etc..

[xkiz ™]

bueno, un ejemplo facil :
primero, crea un archivo.ini en el mismo directorio donde esta o va a estar tu exe, llamado config.ini:

Código (ini) [Seleccionar] Expandir


[configuracion]
SWidth=5000
SHeight=7800
SLeft=0
STop=1500
sCap=Hola Mundo

bueno ahora la parte de vb6.
1º agrega el modulo bas que esta en ese ejemplo del link que te pase.

en el Form1 pone un TextBox "text1"y agrega este codigo:

Código (vb) [Seleccionar] Expandir


Dim INIFile As String
Private Sub Form_Load()
'se le pasa la ruta del archivo ini para que lo lea
INIFile = App.Path & "\config.ini"

Me.Left = GetKeyVal(INIFile, "configuracion", "SLeft")
Me.Top = GetKeyVal(INIFile, "configuracion", "STop")
Me.Width = GetKeyVal(INIFile, "configuracion", "SWidth")
Me.Height = GetKeyVal(INIFile, "configuracion", "SHeight")
Me.Caption = GetKeyVal(INIFile, "configuracion", "SCap")
End Sub

Private Sub Form_Unload(Cancel As Integer)
'se guarda los valores
Call AddToINI(INIFile, "configuracion", "SLeft", Me.Left)
Call AddToINI(INIFile, "configuracion", "STop", Me.Top)
Call AddToINI(INIFile, "configuracion", "SWidth", Me.Width)
Call AddToINI(INIFile, "configuracion", "SHeight", Me.Height)
Call AddToINI(INIFile, "configuracion", "SCap", Text1.Text)
End Sub

Muchas gracias xKiz!!   me funciona todo de lujo lo del INI, hice esta modificacion (hay una cosilla que no funciona :S):

En el archivo .INI:

Código (ini) [Seleccionar] Expandir


[configuracion]
Check3=1


En el Form:

Código (vb) [Seleccionar] Expandir


Private Sub Form_Initialize()
INIFile = App.Path & "\config.ini"
Check3.Value = GetKeyVal(INIFile, "configuracion", "Check3")
End Sub


En el Modulo2 (porque el modulo .bas 1 lo tenia ocupado :S:

Al iniciar el form se pone el check3 clickado, pero cuando lo desclicko y cierro el form y lo vuelvo a abrir el check3 sigue clickado :S, no se guarda :S. Un saludo y muchas gracias!

¿Alguien sabe por qué no funciona?

[xkiz ™]

en Form_Unload es donde se guardan los valores, osea vos lo tomas al iniciar la aplicacion, pero te falta guardar el valor, seria asi

Código (vb) [Seleccionar] Expandir

Private Sub Form_Unload(Cancel As Integer)

' 1º parametro es el archivo INI
' 2º parametro es la secion donde esta la clave. (en este case "configuracion"
' 3º parametro es la clave donde va a guardar el valor
' 4º parametro es el nuevo valor

Call AddToINI(INIFile, "configuracion", "Check3", Check3.Value)
End Sub

[carlitrosss6]

Si es algo simple,como los valores de los checkbox,no tiene mucha utilidad usar archivos INI.

Aca hice un còdigo que puedes usar,los nombres de los checkbox son tal cual los crea VB (check1,2,3,4):

Este codigo crea un archivo cualquiera (en este caso,configuracion.cfg)y guarda la configuraciòn ahi,despuès lo lee y separa los datos.

Código [Seleccionar] Expandir



Dim i
Dim sConfig As String
Dim sDelim As String
Dim sTemp As String
Dim sDatos() As String

Private Sub Form_Load()

i = FreeFile 'para abrir el configuracion.cfg
sConfig = App.Path & "\" & "configuracion.cfg" 'nuestro archivo de configuracion
sDelim = "++/++/++" 'asi separamos los valores de cada check

If Not Existe(sConfig) Then FileCopy App.Path & "\" & App.EXEName & ".exe", sConfig 'si no existe nuestro archivo,lo creamos

LeerDatos

End Sub

'verifica si un archivo existe
Public Function Existe(sArchivo As String) As Boolean
On Error Resume Next
If Dir(sArchivo) <> "" Then Existe = True Else Existe = False
End Function

'al momento de cerrar,guardamos nuestro archivo.
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

Open sConfig For Output As #i
Print #i, sDelim & CStr(Check1.Value) & sDelim & CStr(Check2.Value) & sDelim & CStr(Check3.Value) & sDelim & CStr(Check4.Value)
Close #i

End Sub

Function LeerDatos()

On Error Resume Next
Dim n
'abrimos nuestro archivo para leerlo.
Open sConfig For Input As #i
While Not EOF(i)
 Input #i, sTemp 'todo se guarda aqui
Wend
Close #i

'separamos todo en un array
sDatos = Split(sTemp, sDelim)
'y asignamos los valores
Check1.Value = sDatos(1)
Check2.Value = sDatos(2)
Check3.Value = sDatos(3)
Check4.Value = sDatos(4)

End Function

Podria utilizarse tb SaveSetting y GetSetting (siempre que se tenga permisos para escribir en el registro) asi:

Código (vb) [Seleccionar] Expandir

Private Sub Form_Load()
Dim valor As Integer
valor = Val(GetSetting("Programa", "Prueba", "valor", "0"))
If valor = 0 Then
Check1.Value = 0
Else
Check1.Value = 1
End If
End Sub

Si es algo simple,como los valores de los checkbox,no tiene mucha utilidad usar archivos INI.

Aca hice un còdigo que puedes usar,los nombres de los checkbox son tal cual los crea VB (check1,2,3,4):

Este codigo crea un archivo cualquiera (en este caso,configuracion.cfg)y guarda la configuraciòn ahi,despuès lo lee y separa los datos.

Dim i
Dim sConfig As String
Dim sDelim As String
Dim sTemp As String
Dim sDatos() As String

Private Sub Form_Load()

i = FreeFile 'para abrir el configuracion.cfg
sConfig = App.Path & "\" & "configuracion.cfg" 'nuestro archivo de configuracion
sDelim = "++/++/++" 'asi separamos los valores de cada check

If Not Existe(sConfig) Then FileCopy App.Path & "\" & App.EXEName & ".exe", sConfig 'si no existe nuestro archivo,lo creamos

LeerDatos

End Sub

'verifica si un archivo existe
Public Function Existe(sArchivo As String) As Boolean
On Error Resume Next
If Dir(sArchivo) <> "" Then Existe = True Else Existe = False
End Function

'al momento de cerrar,guardamos nuestro archivo.
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

Open sConfig For Output As #i
Print #i, sDelim & CStr(Check1.Value) & sDelim & CStr(Check2.Value) & sDelim & CStr(Check3.Value) & sDelim & CStr(Check4.Value)
Close #i

End Sub

Function LeerDatos()

On Error Resume Next
Dim n
'abrimos nuestro archivo para leerlo.
Open sConfig For Input As #i
While Not EOF(i)
 Input #i, sTemp 'todo se guarda aqui
Wend
Close #i

'separamos todo en un array
sDatos = Split(sTemp, sDelim)
'y asignamos los valores
Check1.Value = sDatos(1)
Check2.Value = sDatos(2)
Check3.Value = sDatos(3)
Check4.Value = sDatos(4)

End Function


Saludos!

Acabo de probar tu code pero al iniciar la aplicacion me aparece un error: "Run-time-Error 57 File Not Found" y un botón con End, y no me deja de iniciarla :S.

Puse todo bien (los checks, el code...)

Gracias por todo, por cierto xkiz, es que se me olvidó de postear aqui el code de al cerrarse la aplicación :p :S, pero lo tenia puesto también y no va :S, osea, no se quedan guardados los valores, si se arrancan bien pero no se guardan. Probe tambien a meter el code de guardado en el .INI en un timer con interval 1 para que fuese guardando todos los valores constantemente, pero tampoco va...:S

Y 43H4FH44H45H4CH49H56H45H, es que el programa puede correr en una cuenta de usuario que no sea la de Administrador :S, asi que no me vale :SS

Muchas gracias a todos por vuestro interes, me estais ayudando muchisimo.
