Hi, I want to iterate over an array of inputs that belong to certain class (eg."required"). How can I traverse it and get their values ? Something like $$('input required').invoke(function(e){ alert(?input value?) }); thanks ...
Just finished a basic implementation of RMI for a class project, and now I am interested in how it is actually done. Sun is kind enough to provide the source for the majority of the Java classes with the JDK, however an implementation of RemoteRef doesn't seem to be there. I have the source for the interface RemoteRef along with the Serv...

To pop-up a message box, I'm using MessageBox.Show(...). I usually wrap the call in an Invoke: BeginInvoke (new Action (() => { MessageBox.Show ()); })); (I removed a part of the original question which was answered elsewhere) Do I always need to wrap the MessageBox call in an (Begin-)Invoke if I'm calling from a non-GUI thread? ...
So, I was getting back into some .NET programming, and through a new feature in VS.NET 2010, it detected a case where I was trying to modify a control from a thread that didn't create that control, and pointed me to an article on MSDN about how you do this correctly... ' HOW TO WRITE TO A FORM CONTROL FROM A THREAD THAT DIDN'T CREATE TH...

Alternate question: Why is VS10 so keen to complain about Invoke? In my continuing quest to make my app work become the worlds best C# programmer, I have decided that threads are a Good Thing™. MSDN has a helpful article on making thread-safe calls to controls, but it (and seemingly every other article on the subject) obliquely referen...
