Hi, there

I use NETBEAN IDE 6.1. I tried to run CCC.exe by calling exec. But,  
don’t know why it keeps throwing error message,

“C:\Documents and Settings\cheynel\My  
Documents\NetBeansProjects\task1\lib\fexc.rb:8: No such file or  
directory - cannot execute (Errno::ENOENT)”

code is as following,

8 Dir.chdir(“C:\AAA\BBB”)  
9 if File.exist?(“CCC.exe”)  
10 puts “existed”  
11 end  
12 exec(“CCC.exe”)

Does any one have any idea what’s wrong here? Thanks in advance

Try passing the entire path of the file.exe.
