module interesnte para modificar el registro

[rembolso]

hola tengo un module que no me acuerdo de donde me lo descargue . pero cuando intento yamar a esta funcion   me da argumento no opcional

Public Function GetStringVal(ByVal Hkey As HKEYRegConstants, ByVal SubKey As String, ByVal strValue As String) As String
    Dim KeyHnd As Long
    Dim datatype As Long
    Dim lResult As Long
    Dim strBuf As String
    Dim lDataBufSize As Long
    Dim lValueType As Long
    Dim intZeroPos As Integer
    r = RegOpenKey(Hkey, SubKey, KeyHnd)
    lResult = RegQueryValueEx(KeyHnd, strValue, 0&, lValueType, ByVal 0&, lDataBufSize)


    If lValueType = REG_SZ Then

        strBuf = String$(lDataBufSize, " ")
        lResult = RegQueryValueEx(KeyHnd, strValue, 0&, 0&, ByVal strBuf, lDataBufSize)

        If lResult = ERROR_SUCCESS Then
            intZeroPos = InStr(strBuf, Chr$(0))

            If intZeroPos > 0 Then
                GetStringVal = Left$(strBuf, intZeroPos - 1)
            Else
                GetStringVal = strBuf
            End If
        End If
    Else
        Err.Raise vbObjectError + 513, strValue, strValue
    End If
End Function

COMO HAGO PARA Q TODO ESO SE CARGUE EN UN TXTBOX  PARA DESPUES PASARLO A UNA LISTA O A OTRA COSA

hola tengo un module que no me acuerdo de donde me lo descargue . pero cuando intento yamar a esta funcion   me da argumento no opcional

Ese error aparece cuando FALTAN ARGUMENTOS EN UNA FUNCION (Estos argumentos deben ser del mismo tipo del argumento de la funcion/proceso/etc.) para que esta Trabaje adecuadamente por ejemplo:

Código (vb) [Seleccionar] Expandir


public function sumar(byval num1 as integer,byval num2 as integer,optional byval num3 as integer) as integer
    'Se requiere que metas el valor de la variable Num1 y de Num2 sIEMPRE NUMERICOS DE TIPO ENTERO 'Integer'
    'NUM3 es opcionla y puede o no ser asignado un 'X' Numero
    suma=num1+num2+num3
end function


En algún proceso 'X'
Por ende esta se puede llamar de DOS formas

Código (vb) [Seleccionar] Expandir


    dim res as integer
    res= sumar(10,10)
    msgbox res

o de igual forma

Código (vb) [Seleccionar] Expandir


    dim res as integer
    res=sumar(10+10+12)
    msgbox res


Cabe destacar que cuando se asigna opcional un parametro de una funcion este si no le es asignado un valor al momento de llamalo obtiene el valor POR DEFAULT esn este caso será cero por ser tipo numerico y si es textual seria nada de texto, igual podria ser el valor que se le implanta a la Funcion/Proseso/X en cuention

Código (vb) [Seleccionar] Expandir


public function sumar(byval num1 as integer,byval num2 as integer,optional byval num3 as integer=999) as integer
    'Se requiere que metas el valor de la variable Num1 y de Num2 sIEMPRE NUMERICOS DE TIPO ENTERO 'Integer'
    'NUM3 es opcionla y puede o no ser asignado un 'X' Numero
    suma=num1+num2+num3
end function


en la funcion anterior si no se asigna un valor a num3 este por default obtendra el valor 999 si es que se llegase a llamar de la siguiente manera

Código (vb) [Seleccionar] Expandir


dim res=sumar(10,10)
msgbox res 'Da como resultado 1019 por el valor de Num3 q se tomo el valor por default

ok gracias ya lo entendi . haora ya consegui un modulo mejor donde ise un  proyecto igual q el editor de registro . saludos
