Connection Remote | [quote="Kleyton":3fn9t82d]ADS and remote server, where have examples ???[/quote:3fn9t82d]
Check these samples:
<!-- m --><a class="postlink" href="http://www.google.d2g.com/ads/demos/">http://www.google.d2g.com/ads/demos/</a><!-- m -->
There are several samples, written in different GUIs, they all connect to our DBFs in mexico via internet using the RDD ADS and Advantage Internet Server.
Source code included.
Forgot to mention.... open ports 2000 and 2001 if you are working behind a firewall. |
Connection Remote | -xBScript + ASP
Almost 100% compatible to xHarbour code

Connection to XPlane Flight Simulator | Dear Alvaro,
C language does not allow to declare variables after code, in example: (for error in line 106)

Ahora me da este error

Connection to XPlane Flight Simulator | Estimado Alvaro,
Las funciones en C no se pueden llamar directamente desde Harbour, sino que hay que usar lo que se denomina "el sistema extendido":
despues de todos los includes inciales añade este:
#include <hbapi.h>

Connection to XPlane Flight Simulator | Hola Antonio,
Thanks a lot for your help. Everything is working know. I can read and write data from the simulator. I will upload the code when it is finish, just in case someone wants to program de X-Plane simulator. One last question:
I have an array in Fivewin like this
[code=fw:3tsl9k1q]<div class="fw" id="{CB}" style="font-family: monospace;"><br />oSocket<span style="color: #000000;">[</span><span style="color: #000000;">1</span><span style="color: #000000;">]</span>= <span style="color: #000000;">34433</span><br />oSocket<span style="color: #000000;">[</span><span style="color: #000000;">2</span><span style="color: #000000;">]</span>= <span style="color: #ff0000;">"192.168.1.25"</span><br />oSocket<span style="color: #000000;">[</span><span style="color: #000000;">3</span><span style="color: #000000;">]</span>= <span style="color: #000000;">49009</span><br />oSocket<span style="color: #000000;">[</span><span style="color: #000000;">4</span><span style="color: #000000;">]</span>= <span style="color: #000000;">15851</span><br /> </div>[/code:3tsl9k1q]
How can I send the array to a HB_FUNC( )
I use:
pauseSim( oSocket[1],oSocket[2],oSocket[3],oSocket[4] )
and then
[code=fw:3tsl9k1q]<div class="fw" id="{CB}" style="font-family: monospace;"><br /><span style="color: #00C800;">HB_FUNC</span><span style="color: #000000;">(</span> PAUSESIM <span style="color: #000000;">)</span><br /><span style="color: #000000;">{</span><br /> XPCSocket sock;<br /> sock.port = hb_parni<span style="color: #000000;">(</span><span style="color: #000000;">1</span><span style="color: #000000;">)</span>;<br /> strcpy<span style="color: #000000;">(</span> sock.xpIP , hb_parc<span style="color: #000000;">(</span><span style="color: #000000;">2</span><span style="color: #000000;">)</span> <span style="color: #000000;">)</span> ;<br /> sock.xpPort = hb_parni<span style="color: #000000;">(</span><span style="color: #000000;">3</span><span style="color: #000000;">)</span>;<br /> sock.sock = hb_parni<span style="color: #000000;">(</span><span style="color: #000000;">4</span><span style="color: #000000;">)</span>;<br /> <br /> pauseSim<span style="color: #000000;">(</span>sock, <span style="color: #000000;">2</span> <span style="color: #000000;">)</span> ;<br /> </div>[/code:3tsl9k1q]
I there a way to send the array:
[code=fw:3tsl9k1q]<div class="fw" id="{CB}" style="font-family: monospace;">pauseSim<span style="color: #000000;">(</span> oSocket <span style="color: #000000;">)</span></div>[/code:3tsl9k1q]
instead of:
[code=fw:3tsl9k1q]<div class="fw" id="{CB}" style="font-family: monospace;">pauseSim<span style="color: #000000;">(</span> oSocket<span style="color: #000000;">[</span><span style="color: #000000;">1</span><span style="color: #000000;">]</span>,oSocket<span style="color: #000000;">[</span><span style="color: #000000;">2</span><span style="color: #000000;">]</span>,oSocket<span style="color: #000000;">[</span><span style="color: #000000;">3</span><span style="color: #000000;">]</span>,oSocket<span style="color: #000000;">[</span><span style="color: #000000;">4</span><span style="color: #000000;">]</span> <span style="color: #000000;">)</span></div>[/code:3tsl9k1q]
How can I get the array in the HB_FUNC function?
Thank you and regards,

Connection to XPlane Flight Simulator | sock.port = hb_parvni( 1, 1 );
strcpy( sock.xpIP , hb_parvc( 1, 2 ) ) ;
sock.xpPort = hb_parvni( 1, 3 );

If there is some interest I will write a short tutorial and upload the code.

Connection to XPlane Flight Simulator | I made this program to connect Fivewin to the flight simulator “X-Plane”
This could be used to develop an external program for: virtual instructor, flight recording, flight analyzer, moving map, instructor console, and other applications.
The simulator is:
[url:1hs3su6q]https://www.x-plane.com/[/url:1hs3su6q]
I have tested it with x-plane 11, but I think it also works with 9,10 and the newest, 12
I used an API made by someone in the NASA
[url:1hs3su6q]https://github.com/nasa/XPlaneConnect/wiki[/url:1hs3su6q]
[url:1hs3su6q]https://software.nasa.gov/software/ARC-17185-1[/url:1hs3su6q]
You need to install a “plugin” in xplane, as said here:
[url:1hs3su6q]https://github.com/nasa/XPlaneConnect/wiki/XPC-Developer-Information#plugin-information[/url:1hs3su6q]
download the lastest binary of the plugin here:
[url:1hs3su6q]https://github.com/nasa/XPlaneConnect/releases[/url:1hs3su6q]
I modified the C code to adapt it to harbour and I made a class to manage the plugin.
You can read and write almost any data in the sim. I list of the data you can read and modify is here:
[url:1hs3su6q]https://www.siminnovations.com/xplane/dataref/[/url:1hs3su6q]

Connection to XPlane Flight Simulator | Estimado Alvaro,
Muchas gracias por compartirlo.
Podrias publicar aqui algunas capturas de pantalla para que veamos como se ve la aplicación ?
Basicamente lo que tu has programado que utilidad tiene ?
gracias nuevamente |
Connection to XPlane Flight Simulator | Good morning,
What I have programmed serves to create an external application, in this case in Fivewin, to control what is happening inside the simulator from another computer. The simulator usually has one or several dedicated computers.
A typical application is to create an instructor console, where the instructor can see what the student flying the simulator is doing, even over internet, whether he is performing maneuvers correctly, maintaining speeds, altitudes, etc.
For example, take a look at this commercial application; something similar can be done in Fivewin using the connection posted.
[url:21haqvtc]https://www.fs-flightcontrol.com/en/[/url:21haqvtc]
I created a similar application in 2009 for a previous version of the simulator, which I am now updating for the current version of X-Plane.
The simulator currently has 5224 data references, called datarefs, which you can view on this website:
[url:21haqvtc]https://www.siminnovations.com/xplane/dataref/[/url:21haqvtc]
These data range from aircraft altitude, position, and speed to variables related to weather, electrical systems, engines, etc. Some data can only be read, while the majority can be both read and written from the external application.
Here is a photo of the simulator I have been building gradually using OpenCockpits electronics and my own programming.
[url:21haqvtc]https://www.opencockpits.com/catalog/tarjetas-electronicas-iocards-c-21.html[/url:21haqvtc]
[img:21haqvtc]https://live.staticflickr.com/65535/52958764057_3eb94a0010_b.jpg[/img:21haqvtc]
The external view is displayed on a projector positioned behind the simulator.
Best regards,
Alvaro |

Conocer datos de quien me descarga una aplicación | Hola amigos
necesito hacerles la siguiente consulta:
Tengo una aplicación demo, que en realidad es el mismo sistema, pero
con una clave que permite el uso limitado del mismo.
Cada vez que se conecta el usuario de prueba con la misma IP, registra el ingreso, y grabo en
una tabla Mysql la IP y la cantidad de veces que entró.
Habrá alguna forma de tomar de la maquina que instala la aplicación, algún dato más?
Para poder controlar que no hagan mal uso de ésta aplicación de prueba? Por ejemplo, copiar ideas...
Voy a utilizar el NetName para saber el nombre de la compu, pero se podrá tomar algo más
del registro de Windows? Obvio que sin invadir su privacidad, solo para conocer y tratar de
contactar a la persona que descarga el demo.
Desde ya, muchas gracias!

can I see the password of this user ? |
Conocer datos de quien me descarga una aplicación | Creo que los password de usuario de windows no puedes decodificarse, probablemente sean
hash similar a las generadas por md5, las cuales solo puede codificar, mas no decodificar.
hasta la fecha no he visto ningun programa que lo haga, por ejemplo todas las utilidades para desbloquear usuarios a los cuales se le
ha extraviado el password de usuario de windows, optan por dejarlo en blanco, o reemplazarlo, ninguno he visto que diga: tu password de usuario es tal o cual.

Conocer ip pública desde FWH | Patricio,
Ya tengo implementado algo así desde hace algún tiempo. Tengo en mi casa configurado un servidor con una pc viejita, ahí puse un pequeño script php que me devuelve la ip pública obtenida al conectarme con ese script php.
La cuestión es que dependo del servidor para conocer mi ip pública y, quisiera poder hacerlo con alguna función directamente desde FWH.
Por esto consulté si alguien conoce o hizo alguna función para tal fin, y es lo que sigo interesado en conocer.

y me funciona bien en WVista pero al correr el sistema en WXP solo muestra la caratura inicial del MediaPlayer e inmediatamente aparecen errores. Sabes tu a que se debe? No te ha pasado lo mismo? Aun no lo pruebo en W7.

Conocer las veces que una cadena es parte de una matriz | Estimados:
Tengo el siguiente problema y no le encuentro una solución adecuada con una función propia de FW o xHarbour (quizá una combinación entre AEval y AScan sea lo adecuado, pero no he podido dar con la sintaxis adecuada). Lo resumo: si tengo una matriz con varios elementos y quiero conocer la cantidad de veces que un valor especifico se encuentra contenido en la matriz.
Ejemplo_
aMatriz:={"XYZ", "ABC", "ABC", "DEF", "D12345", "ABC", "UVW"", "DEF"}
¿Como hago para conocer la cantidad de veces que la cadena "ABC" está repetida en aMatriz?

Conocer mas información de quien envio un email... | Carlos,
Si el envio del email se hace a través de Yahoo, ó de un proveedor similar, la IP de origen es la de Yahoo, no la de quien escribe el email.
De todas formas puedes revisar la cabecera del email pulsando el botón derecho del ratón sobre el email, en Outlook, y seleccionando Opciones > Encabezados de Internet. Ahí puedes ver si la IP original está indicada ó no. |

Conocer número de columna en TXBrowse | Amigos del foro:
En un browse con TXBrowse tengo 10 columnas de las cuales en pantalla solo caben 5, para ver las restantes 5 columnas el usuario se mueve hacia la derecha hasta aparecer las 5 columnas restantes.
Ahora bien, con el código
[code=fw:2fx153hx]<div class="fw" id="{CB}" style="font-family: monospace;"><br />oCol:<span style="color: #000000;">bLClickHeader</span><br /> </div>[/code:2fx153hx]
Obtengo el número de columna sobre la que el usuario dio clic sobre su header, si en la primera pantalla el usuario da el clic sobre la columna 5 el valor devuelto es 5 y eso es correcto, sin embargo si el usuario se mueve hacia la derecha y da clic sobre la quinta columna que hay en pantalla tambien me devuelve 5, cómo puedo obtener el valor absoluto de la columna ?, en este ejemplo necesito obtener 10, cinco columnas de la primera pantalla y 5 columnas de la segunda pantalla en la que el usuario dio clic. Espero haberme explicado.

Conseguir la maxima velocidad del EXE creado por Harbour | Hola foro,
Basado en sus experiencias, ¿cuáles son los procedimientos a seguir para conseguir la velocidad máxima del EXE generado por Harbour + FWH?
Por ejemplo, estoy pensando en lo siguiente:
1. Sustituir código Harbour por código C (en funciones que pueden ser, o deberían ser, optimizadas mediante el uso de código C).
2. Usar variables locales en lugar de variables globales.
3. Para bases de datos usar ADS/ADT en lugar de DBF (no estoy seguro cual sera mas rapido).
4. Uso de tablas HASH en lugar de arrays
5. Uso de los bloques de código y funciones eval()
Algunas preguntas:
Fivetechsoft o algun compañero del foro han hecho pruebas comparando las velocidades de EXE de harbour vs. EXE de lenguaje C?
Seria posible llamar codigo "assembler" desde Harbour?
Es el P-Code, generado por Harbour, una gran limitación para obtener EXE que corran rapido, comparable a los EXE generados por el lenguage C?
Se pudiera anular (o disminuir notablemente) , esta limitación, llamando a funciones escritas en lenguaje C (o assembler) desde el codigo Harbour?
Saludos,
George |
Conseguir la maxima velocidad del EXE creado por Harbour | George,
La velocidad del .exe depende _MUCHO_ del compilador C que utilices. Te hablo sobre lo que he leído en el foro de Harbour.

Conseguir la maxima velocidad del EXE creado por Harbour | George,
Una aplicación en Harbour finalmente genera un EXE a partir de lenguaje C, luego no hay diferencia, salvo que usamos una máquina virtual que interpreta pcode, pero esa máquina virtual está programada en C y es muy eficiente, posiblemente de las más rápidas que existan <!-- s:-) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":-)" title="Smile" /><!-- s:-) -->
Pero tu pregunta me hace pensar en por que te planteas esto ? Es que tu aplicación va "lenta" ? De ser asi, en que va lenta ? Que partes de ella ?
Y aqui es en donde aparece el concepto de "profiling": [url:kjuufjiv]http://en.wikipedia.org/wiki/Profiling_(computer_programming)[/url:kjuufjiv]
Para acelerar la ejecución de una aplicación hay que identificar los "cuellos de botella" que enlentecen la aplicación. Harbour implementa un profiler (yo lo diseñé) que basicamente mide los tiempos de ejecución de cada función (ó método) y además informa de cuantas veces cada proceso es llamado. Los que se llamen más veces obviamente son los mejores candidatos a ser optimizados, para ganar en velocidad de ejecución.
Otra posible razón de lentitud es el consumo de memoria. Los sistemas operativos usan "memoria virtual" que basicamente se traduce en usar tanto la ram como los discos duros para almacenar información. A mayor consumo de memoria, mayor necesidad de memoria virtual y mayor lentitud. Hoy en día parecería que esto es "improbable" pero, por ejemplo, estos dias estoy probando la nueva versión Mountain Lion de OSX y uno puede experimentar esto perfectamente. A mayor complejidad de los sistemas operativos, más consumo de memoria y mayor lentitud. De ahi que se hace necesario el usar de hardware más rápido. |
Conseguir la maxima velocidad del EXE creado por Harbour | Antonio,
Como siempre, te agradezco tu pronta respuesta asi como tus consejos tecnicos y tu disposicion de ayuda.
Pero antes de seguir quiero aclararte que TODAS las aplicaciones que he desarrollado con Harbour + Fivewin NO son lentas en modo alguno.
Por el contrario son mas rapidas que todos los otros entornos de desarrollo (IDE) que he utilizado y que no lo voy a mencionar para no entrar en discusiones irrelevantes.
Lo que me refiero es a la *optimizacion* del codigo EXE generado por Harbour (aunque gracias al comentario der hmpaquito y al tuyo creo que entiendo mejor ahora).
Por ejemplo si tenemos una database con decenas de millones de records donde los campos pueden ser tratados como un 'string" de bits, talvez podemos usar FWH64 para representar una informacion "binaria" de longitud 64 bits almacenado como un numero entero en formato hexadecimal.
En este caso podemos aplicar el concepto de Bit Map (como expresado en el libro "Clipper 5.2 - Power Programmer Guide", autor Rick Spencer, pags. 688-694), para accesar directamente (y manipular) esta informacion a nivel de bits.
Supongamos que en nuestra database tenemos un tipo de producto X particular, representado por el string de 64 bits expresado en hexadecimal, y que la posicion No. 32 (dentro de ese string de 64 bits) representa un atributo especifico (del producto X) cuando esta "1" y la carencia de ese atributo cuando esta "0". Aqui podemos, de forma muy rapida, mediante operaciones bitwise (AND, OR, o XOR) investigar cuales productos tienen esa caracteristicas y cuales no,
Lo anterior es posible ya que estas operaciones "bitwise" se ejecutan en "computer's clock cycle" asi que nuestros programas realizarian millones de estas operaciones por segundo.
La pregunta mia es, si debido al factor P-Code, que tipo de limitaciones tendremos al usar las operaciones bitwise desde Harbour64 + FWH64?
Si hay limitaciones, en lo que se refiere a la velocidad, podemos evitarlas desarrollando funciones escritas en lenguaje C y llamandolas desde nuestro programas Harbour64?
Cual es tu opinion referente al codigo siguiente que esta siendo llamado desde Harbour64 + FWH64?
Se estaria ejecutando a una velocidad diferente (menor) que si lo llamaramos desde un programa escrito enteramente en C, aunque utilizemos el mismo compilador?

Si, lo mas problabe es que tengas un optimizacion de 0.00000001 segundo... que lo vas a perder 1.000.000 de veces en el siguiente Do While.. que no esta optimizado.
Lo mejor cuando trabajas con compiladores, especialmente con aquellos que generan codigo C puro y duro, es la optimizacion del procedimiento o funcion que ejecuta ciclos, ahi es donde los problemas aparecen, no en la ejecucion lineal de tu programa.
1.-Evita lo que mas puedas las escrituras y lecturas a disco.
2.-Optimiza al maximo los ciclos. (Do While...End / For...Next etc)
3.-Controla al maximo las excepciones (calculos o recuperaciones de divisiones por cero por ej) Aqui en el foro habia un post muy interesante sobre eso.
4.-Cuida el flujo de tu programa, evita pasos innecesarios, respuestas del usuario.
5.-Menos es mas
6.-Crea consultas inteligentes (en el caso de SQL)
7.-Crea indices de acuerdo a lo que vas a necesitar. Con la seguridad de usarlos y de que te permitan mejorar la respuesta de la DB.
Con eso tienes mas que suficiente para "acelerar" tu exe.
Los internals de C, pueden mejorar tu velocidad, pero en cuanto.. casi imperceptible para el usuario.

Conseguir la maxima velocidad del EXE creado por Harbour | Adolfo,
Muy clara tu respuesta.
Estoy de acuerdo contigo en tus sugerencias y sobretodo en que las instrucciones tipo "loops" y de toma de decisiones nos hacen perder en mucho lo poco que gananos.
Por otro lado imaginate un escenario donde usemos unicamente operaciones bitwise, no "for-next" , no "do while - enddo", no "if-else-endif"
Lo que me gustaria saber es como las operaciones "bitwise" se verian afectadas por P-Code.
Bueno, creo que tendria yo mismo que hacer estas pruebas <!-- s:| --><img src="{SMILIES_PATH}/icon_neutral.gif" alt=":|" title="Neutral" /><!-- s:| -->

Conseguir la maxima velocidad del EXE creado por Harbour | Bueno , algunas mejoras, es insignificante pero, te aseguro que esto es una cuello de botella enorme;

La explicación es simple, en el primero , evalua LEN() por cada vuelta, en el otro, no.
Lo mejor que puedes hacer es poner el PROFILE , pero para ello tienes que construir Harbour con ese soporte, porque la aplicación no estará pensada para el cliente final, si no para encontrar los cuellos de botella. |

Comando With Object
WITH OBJECT ... END
Esta es otro de los nuevos comandos de xHarbour que permiten ahorrar
tiempo en tareas repetitivas.
Este comando realiza una cache de un objeto y junto con algunos PCODEs
permite acelerar el acceso a metodos y datas de un objeto.
La sintáxis más común es:
WITH OBJECT oGet
...:Name := "Nombre"
...:VarPut( "Walter" )
END
También se puede usar la función HB_SetWith().
Al pasarle el dato, lo guarda en la cache, y al llamar a esta función
sin parámetros, lo quita.
Para acceder al objeto en el cache se usa la función HB_QWith().
Hay que destacar, que tanto HB_SetWith() como HB_QWith() no son
funciones reales, sino que en tiempo de compilación se transforman en
los mismos PCODEs usados en WITH OBJECT.
HB_SetWith( oGet )
...HB_QWith():Name := "Nombre"
...HB_QWith():VarPut( "Walter" )
HB_SetWith()
Este código genera el mismo PCODE que el ejemplo anterior.
Es posible usar HB_QWith() dentro de WITH OBJECT, pero no es posible
usar la sintáxis reducida (:Name), con HB_SetWith().
WITH OBJECT oGet
...oOtro := HB_QWith() // Correcto
END
HB_SetWith( oGet )
...? :Name // Error
HB_SetWith()
También es posible usar el WITH OBJECT dentro de una macro.
WITH OBJECT oGet
...&(":Name := 'Nombre'")
...&(":VarPut( 'Walter' )")
END
Y el HB_SetWith() también en una macro
&("HB_SetWith( oGet )")
...HB_QWith():Name := "Nombre"
...HB_QWith():VarPut( "Walter" )
&("HB_SetWith()")
WITH OBJECT y HB_SetWith() soportan hasta 32 niveles de anidamiento.
Cada END y cada HB_SetWith() sin parámetros o con parámetro NIL,
"desanidan" un nivel.
Aquí hay un ejemplo de los usos, tomado desde el CVS de xHarbour
xharbour estswith.prg

FOR EACH
Acelerando los recorridos sobre un array.
Es muy común que tengamos que recorrer arrays para hacer diferentes
tipos de tareas, buscar, imprimir, copiar, modificar masivamente, etc.
Además de poder hacerlo con un AEVAL(), podemos usar un bucle FOR-NEXT o
un bucle DO WHILE-ENDDO.
En xHarbour se agrega un nuevo bucle exclusivo para la tarea de recorrer
arrays, el FOR EACH-NEXT.
Veremos más adelante que este bucle tiene algunas particularidades muy
interesantes que son su punto fuerte y razón de ser.
La sintáxis de uso es la siguiente:
FOR EACH _var_ IN _array_
[LOOP]
[HB_ENUMINDEX()]
[EXIT]
NEXT
_array_ puede ser cualquier expresión que retorne un array, un objeto o
una cadena de caracteres.
_var_ puede ser cualquier variable previamente declarada, pero es
recomendable que sea una variable local.
Esta variable va a apuntar a una posición del array, comenzando por la
primera posición.
El FOR EACH va a recorrer todo el array completamente, a menos que se
fuerze la salida anticipada con el comando EXIT.
También es posible usar el comando LOOP de la misma forma que se usa en
el comando FOR-NEXT.
La pseudo-función HB_ENUMINDEX() retorna el número de posición del array
que se está procesando en ese momento.
Funcionamiento:
El comando FOR EACH recorre todo el array _array_ y en cada iteración
guarda en la variable _var_ una referencia a la posición actual del array.
Al finalizar el bucle FOR EACH, la variable _var_ queda con valor NIL,
asi que si necesitamos preservar el valor de dicha variable para usarlo
fuera del bucle, debemos copiarla a otra variable antes de salir.
Qué es eso de que la variable es una referencia ?
La variable del FOR EACH funciona de forma similar a los parámetros de
una función que reciben los datos por referencia.
Es como si fuera algo así: (la siguiente sintáxis es de ejemplo, no es
válida)
_var_ := @_array_[n]
Qué ventajas tiene ?
La ventaja de tener en _var_ una referencia a la posición del array es
que para modificar la posición del array, solo es necesario asignar el
dato que queremos a la variable _var_, y lo que realmente estaremos
haciendo, es modificar el contenido del array.
Donde aplicarlo?
Este comando está especialmente diseñado para recorrer arrays
rápidamente y poder usar o modificar su contenido también de la forma
más rápida posible.
Todas los bucles que recorren un array pueden beneficiarse con el uso de
For each.
Cualquier construcción del tipo:
for n:=1 to Len(aArray)
...
next
puede ser convertida a
for each x in aArray
...
next
Los que usan Fivewin, encontrarán muchas construcciones que pueden
optimizarse usando FOR EACH, en muchos de los fuentes del sistema.
También en otras clases como TSBrowse el desempeño mejora notablemente
al usar FOR EACH.
Encontrarán ejemplos y pruebas aquí: foreach.prg
<http://cvs.sourceforge.net/viewcvs.py/*checkout*/xharbour/xharbour/tests/foreach.prg?rev=1.1>
objlist.prg
<http://cvs.sourceforge.net/viewcvs.py/*checkout*/xharbour/xharbour/tests/objlist.prg?rev=1.1>
ivarref.prg
<http://cvs.sourceforge.net/viewcvs.py/*checkout*/xharbour/xharbour/tests/ivarref.prg?rev=1.3>
Los siguientes ejemplos producen el mismo resultado, pero con tiempos de
ejecución diferentes.
El for-next y el aeval, tardan aproximadamente lo mismo, pero el for
each demora la mitad de tiempo.
aArray := arrray(500000)
nLen := Len(aArray)
for n:=1 to nLen
...aArray[n] := n
next
for n:=1 to nLen
...nSum += aArrray[n]
next
------------------------
aeval( aArray, {|a,n| aArray[n]:=n} )
aeval( aArray, {|a,n| nSum += a} )
------------------------
for each x in aArray
...x := HB_EnumIndex()
next
for each x in aArray
...nSum += x
next

Y como lo hariamos si dependiendo de un criterio dado tenemos que ir BORRANDO algunos elementos del array.
Yo hago esto:[code=fw:1h0md43u]<div class="fw" id="{CB}" style="font-family: monospace;"><span style="color: #00C800;">for</span> x = <span style="color: #000000;">1</span> <span style="color: #0000ff;">to</span> len<span style="color: #000000;">(</span> aArray <span style="color: #000000;">)</span><br /> <span style="color: #00C800;">if</span> << Aquí la condicion deseada >><br /> adel<span style="color: #000000;">(</span> aArray , x , .T. <span style="color: #000000;">)</span><br /> <span style="color: #00C800;">endif</span><br /><span style="color: #00C800;">next</span> x</div>[/code:1h0md43u] |
Conseguir la maxima velocidad del EXE creado por Harbour | jm,
lo haríamos así:
[code=fw:32r4kuhi]<div class="fw" id="{CB}" style="font-family: monospace;">nLen:= Len<span style="color: #000000;">(</span> aArray<span style="color: #000000;">)</span><br />nBorrados:= <span style="color: #000000;">0</span><br /><span style="color: #00C800;">for</span> x = <span style="color: #000000;">1</span> <span style="color: #0000ff;">to</span> nLen- nBorrados<br /> <span style="color: #00C800;">if</span> << Aquí la condicion deseada >><br /> adel<span style="color: #000000;">(</span> aArray , x <span style="color: #000000;">)</span><br /> nBorrados++<br /> x--<br /> <span style="color: #00C800;">endif</span><br /><span style="color: #00C800;">next</span> x<br />aSize<span style="color: #000000;">(</span>aArray, nLen- nBorrados<span style="color: #000000;">)</span></div>[/code:32r4kuhi]
Y en este caso la mejora de velocidad sería doble: primero el Len(aArray) y luego que sólo se hace una operación de redimensionado del array al final del proceso.

Si el array es de muchos registros, como tu sample, te sugiero usar FOR EACH (la explicación en Optimizacion IV).

Conseguir la maxima velocidad del EXE creado por Harbour | Otra recomendacion.
SI se desea ganar velocidad no es recomendable usar ADS local. El uso de esta herramienta disminuye la velocidad de acceso a los archivos a veces hasta en un 40%.
Ads local tiene algunas ventajas como la encriptacion de archivos, manejo de diccionario de datos, uso de instrucciones SQL, etc. pero al costo de disminuir la velocidad de acceso.
Con ADS Servidor no disminuye la velocidad puesto que es cliente servidor.
Saludos. |
Conseguir la maxima velocidad del EXE creado por Harbour | Correcto, es más, mi recomendación es meter ADS y los RDD que necesitemos, y con un simple, usar uno u otro.
Así, si nos encontramos que debemos usar ADS , no tenemos que recompilar o tener 2 exes distintos.
Usar la version 7.0 de ADS, nos servirá para los servidores 7 y superiores.

Conseguir la maxima velocidad del EXE creado por Harbour | Hola,
Mi recomendacion es intentar optimizar procesos. Harbour tendra su limitación dentro de la ejecucion de pcode, pero afinar y obtener buenos ratios estriba mas en la logica del proceso. En cuanto al uso de RDD yo no escatimaria RDD de ADS Local o Server es igual, las ventajas q reporta son idiscutibles aun cuanto pierdes un "poco" de rendimiento, relativo segun como lo mires. Por ejemplo leer 1 millon de registros con DBFCDX estas 1 seg. y con ADSCDX el doble, y ? pero esto es un millon de registros. |
Conseguir la maxima velocidad del EXE creado por Harbour | Carles, correcto, por eso el usar el profile es super útil. Ahi puedes sacar muchas conclusiones y ver donde estás perdiendo el tiempo y ver como puedes llegar a optimizar
las funciones que están perdiendo mucho el tiempo.
Por ejemplo, una cosa tonta es
[code=fw:13gup4l7]<div class="fw" id="{CB}" style="font-family: monospace;"><span style="color: #00C800;">while</span> !eof<span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /> ... etc...<br /> cValor := Funcion_Mia<span style="color: #000000;">(</span><span style="color: #000000;">)</span> <span style="color: #B900B9;">// Devuelve siempre el mismo valor</span><br /> ... etc...<br /> <span style="color: #00C800;">if</span> !empty<span style="color: #000000;">(</span> cValor <span style="color: #000000;">)</span><br /> ...etc....<br /> <span style="color: #00C800;">endif</span><br />end <span style="color: #00C800;">while</span><br /> </div>[/code:13gup4l7]
Convertido a;
[code=fw:13gup4l7]<div class="fw" id="{CB}" style="font-family: monospace;"><br />cValor := Funcion_Mia<span style="color: #000000;">(</span><span style="color: #000000;">)</span> <span style="color: #B900B9;">// Devuelve siempre el mismo valor</span><br /><span style="color: #00C800;">while</span> !eof<span style="color: #000000;">(</span><span style="color: #000000;">)</span><br /> ... etc...<br /> ... etc...<br /> <span style="color: #00C800;">if</span> !empty<span style="color: #000000;">(</span> cValor <span style="color: #000000;">)</span><br /> ...etc....<br /> <span style="color: #00C800;">endif</span><br />end <span style="color: #00C800;">while</span><br /> </div>[/code:13gup4l7]
Estas pequeñas cosas pueden ser vistas por pistas del profile. Por ejemplo, aqui se llamará UNA SOLA LLAMADA, dentro del while, si tenemos 10.0000 regitros, tendremos , 10.0000 llamadas a la función
Funcion_Mia().

Conseguir la maxima velocidad del EXE creado por Harbour | Carles
Yo use por mucho tiempo en mis aplicaciones ADS local, que es gratuito, y en red con solo 10000 registros la velocidad dismiye casi un 40% comparado con el rdd nativo de xharbour teniendo solo tres terminales, y aun usando instrucciones sql. Si usas ads local en un solo equipo la diferencia de velocidad no es notable, ¡pero en red uff¡. Sobre todo notas la lentitud si manejas muchos browse. ADS Server, el que tiene costo, se supone que debe de ser mas rapido porque es cliente servidor aunque yo no lo he probado pero pero con la ventaja del uso del sql el rendimiento debe de ser buenisimo. Con el ADS loxal la velocidad disminuye bastante con cada terminal en la que corre el sistema (aunque el ads local solo permite que se conecten 5 computadoras corriendo la misma aplicacion). No se su opinion pero en mi experiencia el rendimiento de una aplicacion esta mas determinado por la velocidad de acceso a los archivos que por otra cosa. Claro suponiendo que se tiene el hardware adecuado y que no sea el culpable de la lentitud de los programas.
