Donde puedo conseguir la última versión de ADORDD.PRG y

Deseo ver que funciones están desarrolladas hoy en día y saber que puedo hacer y que no.

Saludos

Carlos,

La versión más reciente está en el SVN de Harbour. Existe una versión modificada para xHarbour que está en el CVS de xHarbour.

El código del ADORDD es muy facil de entender, por lo que revisándolo verás como usa el ADO y lo que está operativo de momento.

Gracias Antonio, a eso voy.

No tengo instalado y no se como acceder a SVN de Harbour (de hecho preferiría no hacerlo).
Alguna ayuda? O directamente ADORDD.PRG?

Antonio,

intentando compilar adordd me da este error:

Error: Unresolved external '_HB_FUN_HB_SYMBOL_UNUSED' referenced from C:\LAVWIN\WP32\OBJ\ADORDD.OBJ

uso xharbour.

by **Antonio Linares** » Fri Jul 18, 2008 2:14 pm

Pedro,

Puedes anadir esta funcion en tu PRG:

function HB_SYMBOL_UNUSED( x )

return nil

Editado: Esta es la forma correcta:

#define HB_SYMBOL_UNUSED( symbol ) ( symbol := ( symbol ) )

by **pymsoft** » Fri Jul 18, 2008 4:32 pm

ahora me da este mensaje de error a correr a funcionar un ejemplo:

---------------------------
Stop
---------------------------
Error ADORDD/0 Operation not supported from Errorsys, line: 0
---------------------------
OK
---------------------------

Saludos

Pedro,

Has recompilado adordd.prg con el build de Harbour/xHarbour que estes usando ?

by **MGA** » Fri Jul 18, 2008 5:56 pm

SR. Antonio pode arrumar um exemplo PRG de como conectar ao BD MYSQL com ADORDD?

COM SQLLIB faço assim:

SQL CONNECT ON 'localhost';
PORT 3306 ;
DATABASE "test" ;
USER "root";
PASSWORD '';
LIB 'MySQL'

Obrigado

by **Antonio Linares** » Fri Jul 18, 2008 6:28 pm

En www.fivetechsoft.com/files/adordd.zip hay un ejemplo para acceder a MySQL.

by **Willi Quintana** » Fri Jul 18, 2008 8:40 pm

y para xHarbour?? , hay alguna diferencia o se puede compilar de plano..
Salu2

by **Antonio Linares** » Fri Jul 18, 2008 8:51 pm

Willy,

Puedes compilarlo tal cual. Debe funcionar bien.

Si, compilado con la version de xharbour en uso (incluso he probado con otras mas nuevas que la mia, de hecho, de tantas pruebas ya no se que version estoy usando.. je, je..)

Saludos, ya mañana seguiré con este tema hasta hacerlo funcionar.

Preguntonta...

estoy haciendo pruebas con un servidor mysql en la red local, abro una table que tiene 90.417 registros, demora 4 o 5 segundos en abrirla, y luego cuando hago el browse, es como si trabajara en local, cierro el browse y abro el mismo browse y no demora nada en mostrar los datos.

Me equivoco o los datos que pasan por el cable son solo los visualizados en el browse?? Luego haré las pruebas desde otra adsl y comentaré los resultados.

Saludos

pongo aqui mi codigo:

Code: Select all Expand view: nSecIni := SECONDS() SELECT 0 USE (cDatabase) VIA "ADORDD" TABLE "corpo" MYSQL FROM cServer USER cUser PASSWORD cPass ALIAS corpoSQL NEW msginfo( NTRIM( corpoSQL->( reccount() ) ) + " in " + NTRIM( SECONDS() - nSecIni ) + " secondi..." ) corpoSQL->( browse() ) nSecIni := SECONDS() msginfo( NTRIM( corpoSQL->( reccount() ) ) + " in " + NTRIM( SECONDS() - nSecIni ) + " secondi...(la seconda volta con la tabella aperta)" ) corpoSQL->( browse() ) corpoSQL->( dbCloseArea() )
