[DocumentComplete]

Otra opcion seria usar el evento DocumentComplete. Algo asi como:

Código [Seleccionar] Expandir


Private Sub Web1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
    Static Cuenta As Integer
    If Cuenta <= 100 Then
        Cuenta = Cuenta + 1
        Web1.Document.Forms(0).NOMBREDELBOTON.Value = Cuenta
        Web1.Document.getelementbyid("Boton").Click
    End If
End Sub


Espero q te sirva, saludos.-

[i]

Si tienes un bucle

Código [Seleccionar] Expandir


Dim i as Integer

For i = 0 to 5
     MsgBox i
Next i


La variable i es la que va a ir aumentando hasta llegar a 5. Por ejemplo, si queres agregar en un ListBox 100 numeros, en vez de poner

Código [Seleccionar] Expandir


List1.Additem "1"
List1.Additem "2"
List1.Additem "3"
List1.Additem "4"
...
List1.Additem "100"

Pones:

Código [Seleccionar] Expandir


For i = 1 to 100
      List1.AddItem i
next i


En resumen, la variable es la que va a ir cambiando de valor.

Mi duda es en visual basic.net 2003

Entonces postea en el subforo correspondiente 

Saludos.-

Jajajajaja en donde cabe la idea de usar 254 controles en un solo form?? Probablemente el 90% del codigo sea solo para esconder y mostrar controles xDDDDDD

"Todos los dias se aprende algo nuevo", dijo uno...


jajajaj saludos.-

[Reached Limit: cannot create any more controls for this form]

Hice la prueba y... quien lo hubiera creido:
Reached Limit: cannot create any more controls for this form

Puse exactamente 254 Frames. Asi que supongo que el limite de controles es 255 (contando el Form).

Mira que noticia... Igual, creo que nunca llegare a usar tantos controles en un solo form 


Saludos.-

[wb.(nombre o form(indice)).nombredeltext.value=a tu valor]

Bueno este tema se hablo mucho en el foro. Si lo que no sabes hacer es darle click en la imagen Enviar Mensaje, lo puedes hacer por medio de su nombre o de su ID. Un ejemplo utilizando el ID:

Código [Seleccionar] Expandir


Web1.Document.GetElementById("ImageButton1").Click


Si necesitas llenar los campos busca en el foro que se hablo 23332542354e532534 veces.



PD: Hans, hay un error en tu codigo. No es wb.(nombre o form(indice)).nombredeltext.value=a tu valor, es wb.Document.(nombre o form(indice)).nombredeltext.value=a tu valor


Saludos.-

Perdon, no habia entendido. Es que no se nada de C++ xD.
Que yo sepa no hay ninguna instruccion asi. Si lo que queres hacer es usar un comando en vez de escribir la suma muchas veces (por comodidad) podes hacer lo siguiente:
Declaras la variable a nivel modulo y creas una Sub:

Código [Seleccionar] Expandir


Dim X As Integer

Private Sub Suma()
     X = X + 1
End Sub


Y cada vez que le quieras sumar +1 a la variable simplemente llamas a la Sub:

Código [Seleccionar] Expandir


     Call Suma


Espero que te sirva, saludos.-

Si bueno es mejor que las a variables les asignes un textbox

No, no es mejor. Los textbox ocupan mas espacio en memoria.

ahora para VB hay algo similar?

Código [Seleccionar] Expandir


Dim X as Integer

X = X + 1


xD

[.Text]

Los 2 casos estan bien. Todos los controles tienen una propiedad algo asi como 'por defecto'. Por ejemplo si pones Text1 es lo mismo que poner Text1.Text, ya que .Text es la propiedad por defecto de los TextBoxs. Si usamos un label podemos poner Label1 = "Hola", que seria lo mismo que poner Label1.Caption = "Hola".

Volviendo a la pregunta de las variables: Las variables sirven para almacenar datos temporalmente. Tenes distintos tipos de variables: integer, string, long, byte, variant, etc. Estos tipos de variables se diferencian ya que ocupan diferente espacio en memoria y almacenan diferentes tipos de datos (cadenas de texto, numeros, fechas...).  Bueno, en tu caso queres hacer una calculadora. Lo que podrias hacer es usar un solo textbox. Algo mas o menos asi: introducis el primer numero, luego el boton SUMAR y en ese momento, almacenas el valor del textbox. Luego limpias el textbox para que puedas ingresar otro numero, total el 1ro ya lo tenes almacenado en una variable. Un mini ejemplo:

Código [Seleccionar] Expandir


Dim Num1 As Integer
Dim Num2 As Integer

Private Sub COmmand1_Click()
     If Num1 = 0 Then 'Si en Num1 no se metio nada todavia
          Num1 = Text1.Text 'Almacenamos el 1er numero en la variable
          Text1.Text = "" 'Limpiamos el Text1 para que se pueda ingresar el proximo numero
     Else
          Num2 = Text1.Text 'Agregamos el segundo numero a la variable
          Text1 = Num1 + Num2 'Y ponemos el resultado de la suma en el Text1
     End If
End Sub


Este codigo lo que hace es:
-Introducis el 1er numero a sumar
-Apretas el Command1 (boton de suma en este caso)
-Introducis el 2do numero
-Apretas el Command1
-Te da el resultado

A decir verdad, no es tan necesario usar variables para una calculador sencilla. Si queres hacer algo mas avanzado tendrias que investigar sobre que tipo de numeros soporta cada variable, etc.

No se si quedo muy claro con el ejemplo, pero si necesitas mas ayuda postea.

Saludos.-

Mira, aca te dejo 2 funciones. Una para bajar y otra para subir archivos de cualquier FTP. Si queres vos despues las adaptas a lo que necesites.
