1. Introducción Microsoft Visual Studio Microsoft Visual Studio es un entorno de desarrollo integrado (IDE, por sus siglas en inglés) para sistemas operativos Windows. Soporta varios lenguajes de programación tales como Visual C++, Visual C#, Visual J#, y Visual Basic .NET, al igual que entornos de desarrollo web como ASP.NET. aunque actualmente se han desarrollado

2. Herramientas La barra de herramientas estándar de Visual Basic es otro componente de Visual Basic es donde tienen agrupaos los botones utilizados con frecuencia La barra de herramientas no estándar dentro de visual Basic es donde se agrupan la gran mayoría de objetos y controles que se incluirán en nuestro proyecto.

las extensiones necesarias para muchos otros. Visual Studio permite a los desarrolladores crear aplicaciones, sitios y aplicaciones web, así como servicios web en cualquier entorno que soporte la plataforma .NET (a partir de la versión .NET 2002). Así se pueden crear aplicaciones que se intercomuniquen entre estaciones de trabajo, páginas web y dispositivos móviles.

Herramientas a usar

2.1.1

TextBox

El control TextBox o Caja de texto se utiliza para Ingresar y/o visualizar

sueldo, etc.), en cierta forma hace las funciones de printf, cout, writeln, print, display, etc., pero solo cuando se consideran en su parte de mensajes.

Texto (es un control de entrada de datos)

2.1.3 Button

La propiedad principal de este control

Este control " Botón de comando ", nos

se llama Text. Mediante ella podemos

permite ejecutar alguna rutina, función

asignarle un texto ya sea en tiempo de

o procedimiento, generalmente en el

diseño o tiempo de ejecución al control.

evento click del mismo, para realizar de

2.1.2

Label

Este componente se utiliza para desplegar textos o mensajes estáticos dentro de las formas, textos tales como encabezados, solicitud al usuario del programa para que proporcione algún dato o información(edad, dame

esta manera alguna tarea dentro del programa Como se dijo, se utiliza generalmente en el evento Click par ejecutar alguna acción cuando se produce dicho evento, y es precisamente el evento Click, el que por defecto añade Visual Basic al control

3. Programas Los programas que vamos a realizar son muy fáciles y sencillos solo utilizaremos las 3 herramientas anterior mente comentadas Lo primero que siempre aremos es darle la forma al programa comenzaremos diseñando la forma de nuestro programa a conveniencia 3.1

Programa las 4 operaciones básicas Lavel

Lo primero será crear el formato En este he usado las 3 herramientas De las que hemos estado hablando Ahora vamos al código Lo que tenemos que hacer es Configurar los Buttons Y declarar variadles dependiendo del Programa Se ara eso usando el siguiente código

Button

Damos doble clik en el button “suma” TextBox3.Text = Val(TextBox2.Text) + Val(TextBox1.Text)

El button ”resta” TextBox3.Text = Val(TextBox2.Text) - Val(TextBox1.Text)

El button “multiplication” TextBox3.Text = Val(TextBox2.Text) Val(TextBox1.Text)

El button “divicion”

TextBox3.Text = Val(TextBox2.Text) / Val(TextBox1.Text) Y el codigo final queda Public Class Form1 Dim Text3 As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click TextBox3.Text = Val(TextBox2.Text) + Val(TextBox1.Text) End Sub Private Sub Button2_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click TextBox3.Text = Val(TextBox2.Text) - Val(TextBox1.Text) End Sub Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click TextBox3.Text = Val(TextBox2.Text) * Val(TextBox1.Text) End Sub Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click TextBox3.Text = Val(TextBox2.Text) / Val(TextBox1.Text) End Sub End Class

3.2

Calculadora

Diseñaremos el programa

Después de a ver diseñado la calculadora vamos a programar Comenzaremos con los números Damos doble clik en el button 0 Y escribiremos lo siguiente TextBox1.Text = TextBox1.Text & "0"

Aremos eso con todos lo numero Ahora vamos a los buttons de suma, resta, multiplicación y división En el button suma escribimos

OPE = 1 DATO = Val(TextBox1.Text) TextBox1.Clear() BT2.Enabled = True

En el button resta OPE = 2 DATO = Val(TextBox1.Text) TextBox1.Clear() BT2.Enabled = True

En el button multiplication OPE = 3 DATO = Val(TextBox1.Text) TextBox1.Clear() BT2.Enabled = True

En el button division OPE = 4 DATO = Val(TextBox1.Text) TextBox1.Clear() BT2.Enabled = True

Después el button del igual DATO2 = Val(TextBox1.Text) If OPE = 1 Then RESUL = DATO + DATO2 TextBox1.Text = RESUL BT2.Enabled = True Else If OPE = 2 Then RESUL = DATO - DATO2 TextBox1.Text = RESUL BT2.Enabled = True Else If OPE = 3 Then RESUL = DATO * DATO2 TextBox1.Text = RESUL BT2.Enabled = True Else If OPE = 4 Then RESUL = DATO / DATO2 TextBox1.Text = RESUL BT2.Enabled = True End If End If End If End If

Después el button de borrar

TextBox1.clear () Al inicio del programa declararemos las siguientes variables Dim Dim Dim Dim Dim

DATO As Double DATO2 As Double RESUL As Double OPE As Double PUN As Double

3.3 Horas a minutos y segundos Los siguientes programas son variaciones de los c贸digos que ya hemos visto

El c贸digo Private Sub cal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cal.Click COMBER = Val(TextBox1.Text) TextBox2.Text = COMBER * 60 TextBox3.Text = COMBER * 3600 End Sub Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
