481  Programación / Programación Visual Basic / Re: Ayua con winsock y multiconexiones !! en: 31 Mayo 2005, 00:45 am
Enviale la IP como parámetros de la linea de comandos y luego la obtenés utilizando la función Command$.

Código:
Call Shell ("C:\MyApp.exe" & "127.0.0.1")


Código:
'Procedimiento Sub Main del módulo principal.
'
Sub Main()
       Dim sIp$

  'Obtiene los parámetros de la linea de comandos. En este caso
  'puntual sIp valdrá 127.0.0.1
  '
  sIp = Command$

End Sub

Y no insistas con las preguntas que nadie es ciego, con una vez alcanza y sobra.

Saludos.

Mira el RFC del protocolo FTP, necesitas implementar todo lo que se describe en este RFC.

Desde DirectX no sé si se puede hacer (seguro que si) pero sino lo podés hacer al inicio de la aplicación utilizando la función ChangeDisplaySettings y luego reestablecerla al finalizar el proceso.

Crea una matriz de handles o mejor aún, crea un módulo de clase para cada conexión.

485  Programación / Programación Visual Basic / Re: Microsegundos en: 29 Mayo 2005, 19:35 pm
Todo depende del micro. Para consultar la frecuencia del timer del sistema utiliza la función QueryPerformanceFrequency . Para consultar los ciclos por segundo (no es la frecuencia) utiliza QueryPerformanceCounter . Luego con la función timeGetTime obtenés la hora del sistema en milisegundos y lo podés usar como referencia para realizar las cuentas.

Todo esto no sé si te va a servir para hacer un oscilador de alta frecuencia porque todo depende del hardware. Generalmente el ancho de banda es muy reducido y está en el orden de los 44KHz (la velocidad de muestreo de la placa de sonido).

No se puede, sólo usando proxies o spoofing.

487  Programación / Programación Visual Basic / Re: proyecto final,, ayudenme porfass.. coincidencias en un texto en: 29 Mayo 2005, 00:38 am
La función InStr busca una cadena dentro de otra y, en el caso que la encuentre te devuelve la posición del primer caracter de la cadena, de lo contrario devuelve cero.

Código:
Sub FindStr()
       Dim sText$, sFnd$
       Dim lPos&

  'Texto en el cual se va a buscar, puede ser un cuadro de texto o cualquier String.
  '
  sText = "El conocimiento es el poder de los dioses"
  sFnd = "poder" 'Texto buscado.

  lPos = InStr(1, sText, sFnd)

  If lPos>0 Then
    'Se encontró la cadena. En este caso lPos va a valer 23 porque
    'el primer caracter de la cadena de búsqueda se encuentra en esa posición.
    '
    Call MsgBox("La cadena se encontró en la posición "& lPos, vbExclamation)
  Else
    Call MsgBox("No se encontró la cadena")
  End If
End Sub

Todo esto lo encontrás en un tutorial básico de VB... mejor busca alguno por internet que hay muchos y buenos.

Saludos.

Muy bien explicado el tutorial, sobre todo para los principantes ya que a parte explica los conceptos de programación.

Revisando mis codes encontré un módulo que tiene todos los procedimientos para manipular el registro del sistema usando las funciones de la API. Es un código muy viejo así que disculpen pero mi gramática de código no era muy buena :P.
