Hi all,
I'm using C# and I'd like to check to see if a checkbox on the main form is checked and if so run some code, the problem is I'm in a class file (file with no form, is class file correct?). What is the easiest way to do this?
Thanks Jamie

In SVN you can Check Out (to block others from working on the same file). Can you do this in GIT? It seems like you have to set up a second system that tells people what files are being edited by who with GIT?

If this isn't an option, you can use ajax:
call a page, passing in a request parameter of the file....

I'm iterating through a list of links on a page, creating a URI object for each. When the URI object is created, I don't know whether the URL has a scheme, so when I later call $uri->host() , I will sometimes get

You could also check it's type:
if ($uri->isa('URI::_generic')) { die 'A generic type - not good indeed; it contains:

to see if it's available.

In SVN you can checkout a portion of a repository ie:
http://some-url.com/repo/app1/trunk/plugins/plugin1
Can you do the same when you git clone? As I cannot get this to work
