Hello at all

I have found my solution for remote a browser with PhantomJS
Unfortunately, since yesterday i try several code for read and write in a PIPE or Std

I have found one for read the PIPE of the create process, but i have two problem :

1/ Why Phantom finish alone ?
2/ How can i write in the PIPE created for send the command to Phantom

If someone can help me

Nobody can or want answer

Then.... just a little question perhaps...

Is it possible to run an exe with runprogram or createprocess, and write or read/write in his pipe or stdin/out during all the time that the exe run ??

Because i have also try with the fred code runprogram, readstringprogram, writestringprogram and i can't communicate permanently with phantomjs

Hi KCC,

If I followed (the different topics that you open), what you want to do ultimately is to automate a dialogue via a browser?
There are very effective programs for it (about $ 60)

-- Fr
Si j'ai bien suivi (les différents topics que tu as ouverts), ce que tu veux faire au final est d'automatiser un dialogue via un navigateur ?
Il existe des outils très efficaces pour cela. (non, ce n'est pas autoit)
Les applications web ont la particularité de brouiller volontairement leur code source le plus souvent pour imposer leurs pubs, donc chercher à automatiser via le code source de la page est ch... et souvent presque impossible.
La meilleure manière d'automatiser est donc de mimer le comportement humain en utilisant la reconnaissance d'images, mais pas simplement des morceaux de copie écran: Un outils élaboré sait non seulement comparer des images (sur l'écran ou en mémoire vidéo), mais le faire avec un certain degré de tolérance tant au niveau pixels que % de correspondance (ce qui lui permet de voir un bouton existant grisé ou non par exemple). Il sait aussi utiliser des masques, ce qui permet d'exclure des zones variables (par exemple des coches sur des images).
C'est un outil d'automatisation utilisé aussi comme outil de test. (Programme commercial, donc je ne le cite pas ici)

Hello Mar56UnitedState

Glad to talk to you

Yes, they are numerous years i turn around the subject of remoting browser without 100% of succes

Before i use, OLE and IE, and that's works nearly good
But now, IE is always to late, and not always good updating on all machines

So i try Firefox, all advantage (Portable, last version, add-on, etc...)
But remote FF, is not also simple than IE because not OLE

So, since several years, i try all the ways for do this job
Before, i try SELENIUM, but OOP and i cannot using it directly with PB

And lastly, i see PhantomJS...exactely what i want

Only one executable, open source
But for the moment not really kind with KCC and PB

Other, i know one program, who recognize part of the webrowser by cut little pictures
But i search a more professional method, it's for my office

So thanks for your advice

"FRANCHE"

Oui j'ai croisé ce genre de programme
On prenait des portions de la page en capture et il se chargeait de les retrouver
Y'a même un code de ouf sur ce forum qui fait ça, j'ai essayé de l'utiliser mais pour la recherche de toute une page il etait trop long

Mais, je cherche un truc un peu plus "top moumoute" pour mon boulot

En attendant SELENIUM est vraiment cool, je l'ai essayé il trouve même des balises grace à leur PATH

Il est juste compliqué à programmer car POO et PYTHON sous ses allures simples, ne l'est pas tant que ça

C'est un truc de guedin.....

y'a whatmilles codes de oufs pour utiliser les PIPES, les STD et tout le toutim...
Et pas un ne marche vraiment pour un EXE non PB, sauf la lecture à la creation du process
A croire que une fois lancé, on peut plus causer avec l'EXE
Remarque peut être que c'est pas prevu .....
Y'a des codes qui pilotent la console, mais pour ce qui est de piloter un EXE non PB, c'est le désert de gergovie..

Quoi qu'il en soit merci de ton avis, car je me sent un peu seul sur cette action

Hi KCC,

I thought I found a working solution, but it works only 25% of the time

So I have to investigate it a bit more...

Added a Delay(10) above to avoid high CPU load.

Hello my friend INFRATEC !!!!

it's been several days that I felt alone , me and my phantomJS

And see it's not only the JS, but also the help must be a Phantom

Very sad, i open my webbrowser on my favorite blue page...and what i see...my subject at the begin with a little yellow icon

I look in the right side, and see another time the name of my saver INFRATEC

you never will imagine how you cheers me

I put your splendid code into my IDE and the miracle appears !!!
That's works very well

Never i believe, an also complex code it necessary

Without you, never i can create it

I know now, why i don't have answers, because it's very difficult to remote an EXE with his STDIN

Never i can thank you, your code allow me to manage several EXE, when DLL not exist or if the code is OOP

Again thank you very much, from background of my heart

Kcc is happy and go immediately play with his new toy

I love you....
Your french fan

Kcc

Hello.
Really I liked this program.
I do have a question:
How to modify this program to run the console - OpenConsole() (for StdIn / StdOut) rather than RunProgram("phantomjs.exe").
I dream to launch this another program instead of phantomjs.ehe and talk to her through the pipe StdIO.
That is, this program have to run a modified version of itself(with OpenConsole() only), and be able to exchange messages.
I do not have enough knowledge of purebasic language.
That's what I want to do and to understand how it have to be done.
Help me please.
