  • Creando controles personalizados para asp.net

    - by jaullo
    Si bien es cierto que asp.net contiene muchos controles que nos facilitan la vida, en muchas ocasiones requerimos funcionalidades adicionales. Una de las opciones es recurrir a la creación de controles personalizados. Este será el Primero de varios post que dedicare a mostrar como crear algunos controles personalizados utilizando elementos sumamente sencillos y faciles de entender. Para ello utilizaremos unicamente los regularexpressionvalidator y unas cuantas expresiones regulares. Para este ejemplo extenderemos la funcionalidad de un textbox para que valide números de tarjetas de crédito. Nuestro textbox deberá verificar que existan 16 números, en grupos de 4, separados por un - Entonces, creamos un nuevo proyecto de tipo control de servidor asp.net Primeramente importamos los espacios de nombres Imports System.ComponentModel Imports System.Web Imports System.Web.UI.WebControls Imports System.Web.UI   Segundo creamos nuestra clase Public Class TextboxCreditCardNumber end class Ahora,  le decimos a nuestra clase que vamos a heredar de textbox Public Class TextboxCreditCardNumber           Inherits TextBox end class Una vez que tenemos esto, nuestra base de programación esta lista, asi que vamos a codificar nuestra nueva funcionalidad Declaramos nuestra variables y una propiedad pública que contendrá el mensaje de error que debe ser devuelto al usuario, esta será publica para que pueda ser personalizada.    Private req As New RegularExpressionValidator     Private mstrmensaje As String = "Número de Tarjeta Invalido"     Public Property MensajeError() As String         Get             Return mstrmensaje         End Get         Set(ByVal value As String)             mstrmensaje = value         End Set     End Property   Ahora definimos el metodo OnInit de nuestro control, en el cual asignaremos las propiedad e inicializaremos nuestras funciones    Protected Overrides Sub OnInit(ByVal e As System.EventArgs)         req.ControlToValidate = MyBase.ID         req.ErrorMessage = mstrmensaje         req.Display = ValidatorDisplay.Dynamic         req.ValidationExpression = "^(\d{4}-){3}\d{4}$|^(\d{4} ){3}\d{4}$|^\d{16}$"         Controls.Add(New LiteralControl("&nbsp;"))         Controls.Add(req)         MyBase.OnInit(e)     End Sub   Y por último, definimos el evento render (que es el encarado de dibujar nuestro control) Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)         MyBase.Render(writer)         req.RenderControl(writer)     End Sub   Lo unico que nos queda ahora es compilar nuestra clase y añadir nuestro nuevo control al ToolBox de Controles para que pueda ser utilizado.

  • Validar Textbox para aceptar solo n&uacute;meros

    - by Jason Ulloa
    Una de las necesidades más habituales en el desarrollo es poder validar los controles Textbox para que solo acepten valore numéricos. En este post eso es lo que haremos, nos apoyaremos en el lenguaje javascript para validar nuestro textbox del lado del cliente. Nuestro primer paso será crear la función JavaScript que hará el trabajo, para ello agregamos las etiquetas de javascript <script type="text/javascript"> </script> Posteriormente dentro de esas etiquetas agregaremos el script que hará el trabajo function ValidNum(e) { var tecla= document.all ? tecla = e.keyCode : tecla = e.which; return ((tecla > 47 && tecla < 58) || tecla == 46); } Por último iremos al code behind de la página y en el evento Load agregaremos un nuevo evento al textbox para que reconozca el script. protected void Page_Load(object sender, EventArgs e) { TextBox1.Attributes.Add("onkeypress", "javascript:return ValidNum(event);"); } Con esto, tenemos el textbox validado para aceptar solo números y el punto.

  • La Customer Satisfaction non basta più!

    - by Silvia Valgoi
    La partita per la conquista della fedeltà dei clienti si gioca sempre meno sul prodotto e sempre più sul servizio. Dal momento che il consumatore di oggi è molto più evoluto e autonomo nelle scelte, il servizio deve andare ben oltre la classica interazione da Customer Service: deve rappresentare una vera e propria esperienza d’acquisto positiva. Questo è il risultato, che poi è una conferma, di Oracle Customer Experience Index, una ricerca che Oracle ha commissionato alla società LoudHouse la quale ha raccolto le opinioni di 1400 consumatori europei, di cui 200 italiani. Addirittura, l'81% di chi fa acquisti sarebbe disposto a pagare di più per una migliore customer experience. Un risultato non banale che la dice lunga su quanto il consumatore oggi sia evoluto e pretenda molto dall’azienda con la quale sta interagendo. Il 70% di coloro che hanno risposto al questionario afferma che se l’esperienza d’acquisto fosse negativa smetterebbe di rivolgersi a una determinata azienda e il 92% di questi comprerebbe da un concorrente. Ecco perchè il Customer Service non è più sufficiente, l’esperienza d’acquisto deve essere a 360° a partire dall’approccio al sito web per acquisire informazioni, all’analisi delle interazioni sui social media, fino alla consistenza delle informazioni e delle risposte che vengono fornite attraverso tutti i canali sia fisici sia virtuali. Per far questo Oracle ha dato vita a un’insieme di soluzioni che ha chiamato proprio Customer Experience Suite e spaziano dalla creazione di siti web evoluti, alla possibilità di fare Intelligence sui Social Media, alla capacità di creare un proficuo dialogo con i clienti in fase di postvendita.

  • Membership Provider Parte 1

    - by Jason Ulloa
    Asp.net ha sido una de las tecnologías creadas por Microsoft de mas rápido crecimiento por la facilidad para los desarrolladores de crear sitios web. Una de las partes de mayor importancia que tiene asp.net es el contar con el Membership Provider o proveedor de Membrecía, que permite la creación, manejo y mantenimiento de un sistema completo de control y autenticación de usuarios. Para dar inicio a la serie de post que escribiré sobre que es Membeship y cuáles son las funcionalidades principales daremos unas definiciones. Tal como se menciono anteriormente con el membership provider podemos crear un sistema de control de usuarios completos, entre las funcionalidades principales podemos encontrar: * Creación de usuarios * Almacenamiento de información en base de datos * Autenticación, bloqueos y seguimiento Otras de las ventajas que cabe resaltar, es que, algunos de los controles de asp.net ya traen "naturalmente" en sus funciones la implementación del membership provider, tal como el control "Login" o los controles de estado de usuario, lo cual nos permite que con solo arrastrarlos al diseñador estén funcionando. Membership provider es poderoso, pero su funcionalidad y seguridad se ven aumentadas cuando se integra con otros proveedores de asp.net como lo son RoleProvider y Profile Provider (estos los discutiremos en otros post). En la siguiente figura, podemos ver como se distribuyen algunoS provider creados por Microsoft Antes de iniciar con la implementación de membership debes conocer cosas básicas como el espacio de nombres al que pertenece, el cual es: System.Web.Security que se encuentra dentro del ensamblado System.Web. Algo que debe tomarse en cuenta, es que, para poder utilizar cualquiera de los miembros de la clase, debemos hacer la referencia respectiva. Por defecto, el membership provider está diseñado para trabajar directamente con SQL Server, de ahí que su nombre completo seria SQL Membership Provider. Sin embargo, debido a su gran flexibilidad podemos extenderlo a cualquier base de datos o bien modificarlo para adapatarlo a nuestras necesidades. En los siguientes posts, discutiremos como crear un proveedor personalizado utilizando Entity Framework, separando las capas de acceso y datos y cuáles son las principales funciones que podemos aplicar. En palabras básicas y sin entrar muy hondo en el tema, hemos descrito el objetivo del Membership Provider, para todos los que desean ampliar pueden hacerlo en: http://msdn.microsoft.com/es-es/library/system.web.security.membership%28v=vs.100%29.aspx

  • Google Search not displaying results from sub-pages

    - by nlovric
    I published a new site with some delicate content on September 26, 2012 UTC and no results from sub-pages - only from the main page - appear in Google Search. Entering "neven lovric" "cat out of the bag" into Google Search finds the main page. Is this type of behavior normal? I ask this because the first site was ceased - my account was locked - by the NameCheap, Inc. Risk Assessment Team, allegedly due to PayPal, Inc. reversing my payment for the extension of the registration of the domain before I was able to publish any content on it. In 2011 UTC, Google, Inc. blocked all results for certain keywords from being displayed to their users in the Arab Republic of Egypt during the demonstrations there. So, considering previous events, this is not an unlikely scenario in this case, also.

The example code below shows two methods: The first method, handleButtonPress is a public method exposed on a managed bean. public void handleButtonPress(ActionEvent event){   System.out.println("Event handled");   //optional: partially refresh changed components if command   //issued as a partial submit } The second method is called in response to a user interaction or on page load and dynamically creates and adds a command button. When the button is pressed, the managed bean method – the action handler – defined above is called. The action handler is referenced using EL in the created MethodExpression instance. If the managed bean is in viewScope, backingBeanScope or pageFlowsScope, then you need to add these scopes as a prefix to the EL (as you would when configuring the managed bean reference at design time) //Create command button and add it as a child to the parent component that is passed as an //argument to this method private void reateCommandButton(UIComponent parent){   RichCommandButton edit = new RichCommandButton();   //make the request partial   edit.setPartialSubmit(true);   edit.setText("Edit");                             //compose the method expression to invoke the event handler   FacesContext fctx = FacesContext.getCurrentInstance();   Application application = fctx.getApplication();   ExpressionFactory elFactory = application.getExpressionFactory();   ELContext elContext = facesCtx.getELContext();   MethodExpression methodExpressio = null;   //Make sure the EL expression references a valid managed bean method. Ensure   //the bean scope is properly addressed    methodExpression =  elFactory.createMethodExpression(                              elContext,"#{myRequestScopeBean.handleButtonPress}",                             Object.class,new Class[] {ActionEvent.class});   //Create the command buttonaction listener reference   MethodExpressionActionListener al = null;          al= new MethodExpressionActionListener(methodExpression);    edit.addActionListener(al);     //add new command button to parent component and PPR the component for     //the button to show    parent.getChildren().add(edit);    AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();     adfFacesContext.addPartialTarget(parent);  }

  • What is required to use LODSB in assembly?

    - by Harvey
    What is the minimum set of steps required to use LODSB to load a relative address to a string in my code? I have the following test program that I'm using PXE to boot. I boot it two ways: via pxelinux.0 and directly. If I boot it directly, my program prints both strings. If I boot via pxelinux.0, it only prints the first string. Why? Working technique (for both): Set the direction flag to increment, cld Set ds to cs Put the address (from start) of string in si Add the starting offset to si Non-working technique (just for pxelinux): Calculate a new segment address based on (((cs << 4) + offset) >> 4) Set ds to that. (either A000 or 07C0) text here to fix bug in markdown // Note: If you try this code, don't forget to set // the "#if 0" below appropriately! .text .globl start, _start start: _start: _start1: .code16 jmp real_start . = _start1 + 0x1fe .byte 0x55, 0xAA // Next sector . = _start1 + 0x200 jmp real_start test1_str: .asciz "\r\nTest: 9020:fe00" test2_str: .asciz "\r\nTest: a000:0000" real_start: cld // Make sure %si gets incremented. #if 0 // When loaded by pxelinux, we're here: // 9020:fe00 ==> a000:0000 // This works. movw $0x9020, %bx movw %bx, %ds movw $(test1_str - _start1), %si addw $0xfe00, %si call print_message // This does not. movw $0xA000, %bx movw %bx, %ds movw $(test2_str - _start1), %si call print_message #else // If we are loaded directly without pxelinux, we're here: // 0000:7c00 ==> 07c0:0000 // This works. movw $0x0000, %bx movw %bx, %ds movw $(test1_str - _start1), %si addw $0x7c00, %si call print_message // This does, too. movw $0x07c0, %bx movw %bx, %ds movw $(test2_str - _start1), %si call print_message #endif // Hang the computer sti 1: jmp 1b // Prints string DS:SI (modifies AX BX SI) print_message: pushw %ax jmp 2f 3: movb $0x0e, %ah /* print char in AL */ int $0x10 /* via TTY mode */ 2: lodsb (%si), %al /* get token */ cmpb $0, %al /* end of string? */ jne 3b popw %ax ret .balign 0x200 Here's the compilation: /usr/bin/ccache gcc -Os -fno-stack-protector -fno-builtin -nostdinc -DSUPPORT_SERIAL=1 -DSUPPORT_HERCULES=1 -DSUPPORT_GRAPHICS=1 -DHAVE_CONFIG_H -I. -Wall -ggdb3 -Wmissing-prototypes -Wunused -Wshadow -Wpointer-arith -falign-jumps=1 -falign-loops=1 -falign-functions=1 -Wundef -g -c -o ds_teststart_exec-ds_teststart.o ds_test.S /usr/bin/ccache gcc -g -o ds_teststart.exec -nostdlib -Wl,-N -Wl,-Ttext -Wl,8000 ds_teststart_exec-ds_teststart.o objcopy -O binary ds_teststart.exec ds_teststart

  • Quick, beginner MASM register question - DX:AX

    - by Francisco P.
    Hello, I am currently studying for an exam I'll have on x86 assembly. I didn't have much luck googling for ":", too common of a punctuation mark :/ IDIV - Signed Integer Division Usage: IDIV src Modifies flags: (AF,CF,OF,PF,SF,ZF undefined) Signed binary division of accumulator by source. If source is a byte value, AX is divided by "src" and the quotient is stored in AL and the remainder in AH. If source is a word value, DX:AX is divided by "src", and the quotient is stored in AL and the remainder in DX. Taken from "Intel Opcodes and Mnemonics" What does DX:AX mean? Thanks a lot for your time :)

  • MBR Booting from DOS

    - by eflukx
    For a project I would like to invoke the MBR on the first harddisk directly from DOS. I've written a small assembler program that loads the MBR in memory at 0:7c00h an does a far jump to it. I've put my util on a bootable floppy. The disk (HD0, 0x80) i'm trying to boot has a TrueCrypt boot loader on it. It shows up the TrueCrypt screen, but after typing in the password it crashes the system. When I run my little utlility (w00t.com) on a normal WinXP machine it seams to crash immedealty. Apparently I'm forgetting some crucial stuff the BIOS normally does, my guess is it's something trivial. Can someone with better bare-metal DOS and BIOS experience help me out? Heres my code: .MODEL tiny .386 _TEXT SEGMENT USE16 INCLUDE BootDefs.i ORG 100h start: ; http://vxheavens.com/lib/vbw05.html ; Before DOS has booted the BIOS stores the amount of usable lower memory ; in a word located at 0:413h in memory.

    Lets say within my program I want to execute two child processes, one to to execute a "ls -al" command and then pipe that into "wc" command and display the output on the terminal. How can I do this using pipe file descriptors so far the code I have written: An example would be greatly helpful int main(int argc, char *argv[]) { int pipefd[2] pipe(pipefd2); if ((fork()) == 0) { dup2(pipefd2[1],STDOUT_FILENO); close(pipefd2[0]); close(pipefd2[1]); execl("ls", "ls","-al", NULL); exit(EXIT_FAILURE); } if ((fork()) == 0){ dup2(pipefd2[0],STDIN_FILENO); close(pipefd2[0]); close(pipefd2[1]); execl("/usr/bin/wc","wc",NULL); exit(EXIT_FAILURE); } close(pipefd[0]); close(pipefd[1]); close(pipefd2[0]); close(pipefd2[1]); }

  • Must I loop to search results for a specific value?

    - by tag
    I have a table in the database: name Opinion Tim Tim has an opinion John other random text Dan Dan's random text Al Al says something else I call this data and get it back in getRecords.lastResult To access John's opinion, I could use: getRecords.lastResult[1].opinion But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion. My guess is I need some sort of a loop? Is there an easier way to search for John directly without a loop?

At the same time, if I wanted to reuse this button, so that other event listeners can register with it, are these the appropriate steps I should do: override addActionListener(ActionListener action) override removeActionListener(ActionListener action) have a private variable like List <ActionListener> list = new List <ActionListener>() to keep track of when events get added and some sort of function with for loop to run all the actions: public void runListeners() { for (ActionListener al : list) { al.actionPerfomed; } } I'm not really sure if this is the way you can do it or if there are other things I am missing. Like does my custom class have to be implements ActionListener? Thanks.
