Re: [amibroker] how to? with script, download data from web

["Prashanth" <prash454@xxxxxxxxxxxxxxxxx>]

Hi,
 
I had a similar problem and TJ gave me this 
script, but there is a small prob which I have given at the end of this 
messge,
 

URLGet is not a JScript function. 
You can not type it directly in JScript. It is an external program that you have 
to "run" from JScript via Run method WshShell object, 
as shown in the newsletter, <FONT face=Arial 
size=2>that I pointed to you before: <A 
href="">http://www.amibroker.com/newsletter/02-2001.html
 

/* first, create Shell object that 
allows us to run external programs */WshShell = new 
ActiveXObject( "WScript.Shell" );
/* this handy function takes just URL 
and local file name and calls URLGet program to do the work 
*/function Download( URL, 
filename ){

  if( WshShell.Run( "URLGet " + URL + " " + 
  filename, 0, true ) == 0 ) return true;
  WScript.echo("Download of " + URL + " failed." 
  );
  return false;
}
/* Now you can use above function 
to download and store the file */  
Download( "My Http Address/ACC.txt" 
"c:\\mydata\\ACC.txt" ); 
But I still have a 
small problem, When I run the script, nothing happens. What can be the problem. 
I can download the file using URLget, but using this Script I wanted to update 
the said file - I do not want to download the whole file again and again. All 
ideas welcome since I badly have to use this feature.
