2,902,571 | 2,902,572 | C# - display information about custom objects in VS during debugging | <p>I have a set of C# classes, extending an abstract class. There is an abstract method <code>void Show()</code> on the parent. The extending classes are part of a graph with cycles. The implementations of Show invoke many times <code>Console.Write()</code>. Between the console writes there are recursive and other calls.</p>
<p>My problem - it is very hard to debug without an easy way to see the state of the graph. I've tried to make that method <code>string Show()</code>, but it is very hard to do properly with all the recursion and cycles. Can you suggest a better approach?</p>
<p>Thanks, Sam</p>

4,695,711 | 4,695,712 | Can a java Map return a size of -1? | <p>I have some code that creates a List, initialized with the size of a Map:</p>
<pre><code>private Set<String> mKeys = new HashSet<String>(64);
....
List<String> keyList = new ArrayList<String>(mKeys.size());
</code></pre>
<p>I am seeing an exception: java.lang.IllegalArgumentException: Illegal Capacity: -1</p>
<p>Can a Map return a size of -1? I am looking at the source code for HashSet, which backed by a HashMap. The source code for HashMap shows the internals where elementCount is always decremented on a removeEntry() call. Also, the methods for HashMap.empty() reply on elementCount being == 0, which would return false if elementCount was -1.</p>
<p>Has anyone run into this before? I can code around it, but that feels like a hack, which makes me think I am doing something wrong with the current code.</p>
<p>EDIT: I was trying to simplify the problem originally. The Set I'm using is actually defined as</p>
<pre><code>private static Set<String> mKeys = Collections.synchronizedSet(new HashSet<String>(64));
</code></pre>
<p>EDIT: The key here may be in the synchronizedSet. From the JavaDoc</p>
<pre><code>It is imperative that the user manually synchronize on the returned set when iterating over it:
Set s = Collections.synchronizedSet(new HashSet());
...
synchronized(s) {
Iterator i = s.iterator(); // Must be in the synchronized block
while (i.hasNext())
foo(i.next());
}
Failure to follow this advice may result in non-deterministic behavior.
</code></pre>
<p>Non-deterministic behavior to me might include a size of -1. I need to go back and make sure I an synchronizing correctly when iterating over the set, but I suspect this is the problem.</p>

814,808 | 814,809 | Specific types in implementing class when using an interface | <p>Consider the following code sample:</p>
<pre><code>interface IData {
int Count();
}
interface IOperations {
IData Foo();
double Bar(IData a);
}
class Data1 : IData {
public int Count() { return 37; }
public double SomethingElse { get; set; }
}
class Ops1 : IOperations
{
public Data1 Foo() { return new Data1(); } // want to return specific type here
public double Bar(Data1 x) { ... } // want to get specific type here
// and not use operator as everywhere
}
// more definitions of classes Data2, Ops2, Data3, Ops3, ...
// some code:
Ops1 a = new Ops1();
Data1 data = a.Foo(); // want Data1 here not IData!
double x = a.Bar(data);
</code></pre>
<p>I could of course just use <code>public IData Foo() { return new Data1(); }</code>:</p>
<pre><code>// some code
Ops1 a = new Ops1();
Data1 data = a.Foo() as Data1;
</code></pre>
<p>but with <code>as</code> everywhere, the code is quickly becoming confusing.</p>
<p>I wonder if there is a good design pattern to achieve this in a clear and strong way?</p>
<p><strong>Edit:</strong> Is is important, that Ops and Data share a common base class:</p>
<pre><code>List<IOperations> ops = ...;
List<IData> data = ...;
List<double> result = ...;
for(int i=0; i<ops.Count; i++)
result[i] = ops[i].Bar(data[i]);
</code></pre>
<p>So for the case with the return type, I wonder that this is forbidden, because I satisfy the requirement of the interface. In the case with parameters probably there is some additional (template) layer required.</p>

<p>this is a small code which serializes my message object(this object contains some text message) and writes it to a binary file. This works perfectly if the object carries only one word for a text but if many words are sent, obviously it is overwritten in the binary file. So how do i alter the snippet to create multiple files dynamically and then store different message in different file? </p>

<pre><code> ...
success: function(msg) {
$("[id$='_btnUpdateGrid']").trigger('click');
$("#new_dialog").dialog('close');

<p>This has worked just fine with 1.3.2. Updated to 1.4.1 and it no longer hits the code-behind. The AJAX still works but I have to manually refresh the page to update the grid. </p>
<p>Also, I can hit client side event handlers (e.g OnClientClick="alert('hello')") so I know the click is still happening just not the code-behind event handler. It's like jquery is somehow blocking the page from doing just that now. I have verified this by just changing the version number in the script reference path and seeing the functionality change.</p>

If I set an alarm using my app, say for 5 minutes from now, and then close the app, how would I code it so that my app activity comes back to the front? </p>
<p>This is basically the same as the clock app already on most android phones. I'm doing this to allow the user to stop the alarm. Would I be right in saying that I would have to modify my existing code to, when the alarm is run, launch a new intent to bring the activity to the front? Or can I simplify this and only have an alertdialog or something open instead of opening the entire app?</p>
<p>Any links would be appreciated</p>
