un pequeño ejemplo ...meteo.prg

[Silvio.Falconi]

I tried from test

cDir := "https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid in (select woeid from geo.places(1)"
cDir:= cDir + " where text= '"+ cCity +"' and lang='"+cLanguage+"' ) and u='"+cUnits+"'&format=" + Formato


but not run ---make error ...

[Silvio.Falconi]

strange very strange on console on yahoo web site I have the text in italian language but when I insert this string on fwh test not run ...and it not make error

select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="TERAMO,AB" and lang="it-IT")


why ?

Dear Acuellar ,
can post all source code with proxy funcs? ( because I not understood how)

If I insert

it run ok

but if I insert it on Meteo test not run

but it not request user and password ?

[mastintin]

silvio , has colocado el #define ? :

Manuel perhaps it need another command ?

[Silvio.Falconi]

Sorry, Manuel

Now run also with proxy

with My foot ( n.47) I moved the network cable

[Silvio.Falconi]

For all and also for my Great friend Manuel

Now it is complete ...what need also ?


Add the possibility to insert proxy setup

ON init it ask you if want use proxy if yes it ask you proxy datas and save them on inifile ( meteo.ini)

Manuel

Tengo un programa con éste ejemplo y dejó de funcionar. No conecta.
Será que Yahoo habrá realizado algún cambio.
Hay otra manera de hacerlo?

Gracias por la ayuda.

[mastintin]

Sin tocar nada aqui esta funcionando bien ...
