When using the Visual Studio shortcut/snippets is it possible to specify the collection in advance/automagically, rather than fill in the green boxes afterwards? In this case, I'm trying to come up with something like the following with the fewest possible number of keystrokes: foreach (ListItem item in ListBox1.Items) { // } For...
I have something like this: Map<String, String> myMap = ...; for(String key : myMap.keySet()) { System.out.println(key); System.out.println(myMap.get(key)); } So is myMap.keySet() called once in the foreach loop? I think it is, but want your opinion. I would like to know if using foreach in this way (myMap.keySet()) has a pe...

I need to serialize a proxy class. The class uses __set and __get to store values in an array. I want the serialization to look like it is just a flat object. In other words, my class looks like: class Proxy { public $data = array(); public function __get($name) { return $data[$name] } } and I want a foreach ...
Imagine the following code: class foreach_convert { public static void method2() { List<IComparable> x = new List<IComparable>(); x.Add(5); foreach (string s in x) { //InvalidCastException in runtime } } } I wonder, why is this foreach behavior so... not C#-like? What ha...

I have a BOOST_FOREACH loop to iterate over a list. Unfortunately, I also need to cache an iterator to a particular item. typedef List::iterator savedIterator; BOOST_FOREACH(Item &item, list) { // stuff... if (condition) savedIterator = &item; // this won't work // do more stuff... } Obviously I can do this using a list.b...
Hello, I am trying to create an object from an Active Directory base on a simple login. The problem is that some of the login information is valid. How could I just use a try-catch so that if an exception is thrown, just skip to the next login? Here is the code: foreach (var PharosUserItem in ListRef) { ADUser User; try {...
If I have the following array in Perl: @x = qw(a b c); and I iterate over it with foreach, then $_ will refer to the current element in the array: foreach (@x) { print; } will print: abc Is there a similar way to get the index of the current element, without manually updating a counter? Something such as: foreach (@x) { ...

I am looking for the equivalent of a foreach loop with keys in Actionscript. In PHP this would be: foreach($array as $key => $value) { } I found two solutions that will work, but I am wondering if there is a better way to do this. The first solution is to use the for..in loop. Which gives you the keys, but you still have to use the ke...
Yes, I know, yet another question about mutable objects. See this for general background and this for the closest analogue to my question. (though it has some C++ specific overtones that don't apply here) Let's assume that the following pseudo code represents the best interface design. That is, it's the clearest expression of the busin...
So, I never knew this and I want to get some clarifcation on it. I know if you do foreach (@list){ if you change $_ in that loop it will affect the actual data. But, I did not know that if you did foreach my $var1 (@list){ If you changed $var1 in the loop it would change the actual data. :-/ So, is there a way to loop over @list ...
