Read data web - 10/21/18 16:59

Hello,

I'm using :

file_append("cot.txt",
http_transfer("http://www.zorro-trader.com/",0),1024);

contentWeb=file_content ("cot.txt");
printf("Webpage %s",contentWeb);

and I Works perfectly but there is a problema because the size of web is bigger than 1024 and when I get the web completely ( without 1024) the file is correct but the Zorro crash.....

Any idea ?
Thanks in advance

The lines look unsuspicious. Can you post the complete script in a version that crashes?

This is the complete code:


string contentWeb;
string copy="";


function main(){

file_delete("cot.txt"); // delete previous report
file_append("cot.txt",
http_transfer("https://www.zorro.com",0),0);

contentWeb=file_content ("cot.txt");
strcpy(copy,contentWeb);
printf("Content es %s",copy);

printf("nfinished");



}

it crash...........if I change http_transfer("https://www.zorro.com",0),0);
by
http_transfer("https://www.zorro.com",0),1024); -> There is not problem

Copying a large website into an empty string is no good idea.

Of course it crashes. You need a string of sufficient length for copying a website. Define it either as a static char array, or allocate it with mem_alloc. Look into the links by AndrewAMD. And also consider looking in a C book: when you begin to work with arrays and allocations, it's a bit beyond the simple C from the workshops in the manual.
