Hello,

I have created small program to download files from website. I am using  
netbeans and JRuby. When I run program, it downloads files no problem,  
however, if I run it outside netbeans, it downloads files of similar  
size, but they are corrupted and compare by content shows many  
differences.

Code:

def download\_to\_folder(folder, replay\_name,id)  
Dir.chdir(“D:\Starcraft\Replays\”+folder)  
writeout = open(replay\_name, “w”)  
writeout.write(open(“[http://www.sc2rep.com/replays/download?id=](http://www.sc2rep.com/replays/download?id=)”+id.to\_s).read)  
writeout.close  
end

Configuration (maybe it helps): Windows 7 64bit, Ruby 1.9.1-p243,  
Netbeans 6.8 with JRuby 1.8.7 (2009-11-04 patchlevel 174) [java]

Try it with open(replay\_name, “wb”) to open the file in binary mode.
