copied!<p>Windows does not have cron, but it does have an equivalent task scheduler.</p> <p>See <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29.aspx" rel="nofollow">this overview</a> of the scheduler and <a href="http://technet.microsoft.com/en-us/library/cc725744.aspx#BKMK_spec_day" rel="nofollow">this specific example</a> for configuring a "Wednesday-only" task.</p> <p>A counter like you are describing does seem like the kind of value that you would normally store in a database, e.g. <a href="http://www.sqlite.org/" rel="nofollow">SQLite</a> is lightweight/convenient. You could take a look at <a href="http://www.skorks.com/2009/08/installing-and-using-sqlite-with-ruby-on-windows/" rel="nofollow">this nice intro on SQLite in Windows</a>.</p> <p><strong>Update</strong></p> <p>In answer to your question in the comments...</p> <blockquote> <p>so I can run .rb file or ruby task with this ?</p> </blockquote> <p>Yes, you can. Here is a small recipe:</p> <p>1) Install Ruby with this installer: <a href="http://rubyinstaller.org/" rel="nofollow">http://rubyinstaller.org/</a> Note: Make sure to check the checkboxes that set it up to be able to run standalone Ruby scripts as-is.</p> <p>2) Write a sample ruby script to periodically run. E.g., here's one that will throw a Windows dialog:</p> <pre><code>require 'Win32API' title = "Test" text = "Testing..." dialog = Win32API.new('user32', 'MessageBox', 'LPPL', 'I') result = dialog.call(0, text, title, 1) </code></pre> <p>3) And here's an example of "cron" setup from cmd.exe: schtasks /create /sc minute /mo 1 /tn "Test Script" /tr c:\Users\manzoid\dev\test.rb</p>
