<p>Despite my lack of coding knowledge I managed to write a small little app in VB net that a lot of people are now using. Since I made it for free I have no way of knowing how popular it really is and was thinking I could make it ping some sort of online stat counter so I could figure out if I should port it to other languages. Any idea of how I could ping a url via vb without actually opening a window or asking to receive any data? When I google a lot of terms for this I end up with examples with 50+ lines of code for what I would think should only take one line or so, similar to opening an IE window.</p>
<p>Side Note: Would of course fully inform all users this was happening.</p>

<p>I have 3 PDF documents that are generated on the fly by a legacy library that we use, and written to disk. What's the easiest way for my JAVA server code to grab these 3 documents and turn them into one long PDF document where it's just all the pages from document #1, followed by all the pages from document #2, etc.</p>
<p>Ideally I would like this to happen in memory so I can return it as a stream to the client, but writing it to disk is also an option.</p>

<p>I was investigating the rapid growth of a SQL Server 2005 transaction log when I found that transaction logs will only truncate correctly - if the sys.databases "log_reuse_wait" column is set to 0 - meaning that nothing is keeping the transaction log from reusing existing space. </p>
<p>One day when I was intending to backup/truncate a log file, I found that this column had a 4, or ACTIVE_TRANSACTION going on in the tempdb. I then checked for any open transactions using DBCC OPENTRAN('tempdb'), and the open_tran column from sysprocesses. The result was that I could find no active transactions anywhere in the system.</p>
<p>Are the settings in the log_reuse_wait column accurate? Are there transactions going on that are not detectable using the methods I described above? Am I just missing something obvious?</p>

<p>I'm trying to read a .doc file into a database so that I can index it's contents. Is there an easy way for PHP on Linux to read .doc files? Failing that is it possible to convert .doc files to rtf, pdf or some other 'open' format that is easy to read?</p>
<p>Note, I am not interested in .docx files. </p>

<p>I recently started using Rake to build some of my (non-ruby) packages. Rake is nice, but what I found missing is a way to do hierarchical builds (aggregate Rakefiles in subdirectories). Since this is a common feature in most other build tools, I'm wondering if someone more familiar with Rake has a good solution.</p>

<p>I want to extend an existing application I made to make it set mixer volume by wheel-scrolling over it's notification area icon.</p>
<p>As far as I know, the notification area doesn't receive any WM_MOUSEWHEEL messages, but still I found an application that does exactly what I want to achieve (<a href="http://www.actualsolution.com/power_mixer/" rel="nofollow noreferrer">http://www.actualsolution.com/power_mixer</a>).
Using WinspectorSpy I've noticed some strange messages the application's form receives: 0x000003d0 and 0x000003d1, but I found no references about them.</p>
<p>Does anyone have any idea on how I could achieve the desired functionality?</p>

<p>I'm looking for an LDAP libracy in C or C++ that allows me to specify a list of LDAP hostnames instead of a single hostname. The library should then use the first one it can connect to in case one or more of the servers is/are down. I'm sure it'd be easy to wrap an existing library to create this, but why reinvent the wheel?</p>

<p>How can I cast long to HWND (C++ visual studio 8)?</p>
<pre><code>Long lWindowHandler;
HWND oHwnd = (HWND)lWindowHandler;
</code></pre>
<p>But I got the following warning:</p>
<blockquote>
<p>warning C4312: 'type cast' : conversion from 'LONG' to 'HWND' of greater size</p>
</blockquote>
<p>Thanks.</p>

<p>Basically, I would like a brief explanation of how I can access a SQL database in C# code. I gather that a connection and a command is required, but what's going on? I guess what I'm asking is for someone to de-mystify the process a bit. Thanks.</p>
<p>For clarity, in my case I'm doing web apps, e-commerce stuff. It's all ASP.NET, C#, and SQL databases.</p>
<p>I'm going to go ahead and close this thread. It's a little to general and I am going to post some more pointed and tutorial-esque questions and answers on the subject.</p>

<p>When a user goes to my site, my script checks for 2 cookies which store the user id + part of the password, to automatically log them in. </p>
<p>It's possible to edit the contents of cookies via a cookie editor, so I guess it's possible to add some malicious content to a written cookie?</p>
<p>Should I add <code>mysql_real_escape_string</code> (or something else) to all my cookie calls or is there some kind of built in procedure that will not allow this to happen?</p>

<p>I've kind of backed myself into a corner here.</p>
<p>I have a series of UserControls that inherit from a parent, which contains a couple of methods and events to simplify things so I don't have to write lines and lines of near-identical code. As you do. The parent contains no other controls.</p>
<p>What I want to do is just have one event handler, in the parent UserControl, which goes and does stuff that only the parent control can do (that is, conditionally calling an event, as the event's defined in the parent). I'd then hook up this event handler to all my input boxes in my child controls, and the child controls would sort out the task of parsing the input and telling the parent control whether to throw that event. Nice and clean, no repetitive, copy-paste code (which for me <em>always</em> results in a bug).</p>
<p>Here's my question. Visual Studio thinks I'm being too clever by half, and warns me that "the method 'CheckReadiness' [the event handler in the parent] cannot be the method for an event because a class this class derives from already defines the method." Yes, Visual Studio, <em>that's the point</em>. I <em>want</em> to have an event handler that only handles events thrown by child classes, and its only job is to enable me to hook up the children without having to write a single line of code. I don't need those extra handlers - all the functionality I need is naturally called as the children process the user input.</p>
<p>I'm not sure why Visual Studio has started complaining about this now (as it let me do it before), and I'm not sure how to make it go away. Preferably, I'd like to do it without having to define a method that just calls CheckReadiness. What's causing this warning, what's causing it to come up now when it didn't an hour ago, and how can I make it go away without resorting to making little handlers in all the child classes?</p>

<p>NHibernate is not really a good fit for our environment due to all the dependencies. (Castle, log4net etc.)</p>
<p>Is there a good lightweight alternative?</p>
<p>Support for simple file based databases such as Access/SQLite/VistaDB is essential.</p>
<p>Ideally, something contained in a single assembly that only references .NET assemblies. If it only requires .NET framework 2.0 or 3.0 that is a bonus.</p>

<p>I've recently started developing applications for the Blackberry. Consequently, I've had to jump to Java-ME and learn that and its associated tools. The syntax is easy, but I keep having issues with various gotchas and the environment. </p>
<p>For instance, something that surprised me and wasted a lot of time is absence of real properties on a class object (something I assumed all OOP languages had). There are many gotchas. I've been to various places where they compare Java syntax vs C#, but there don't seem to be any sites that tell of things to look out for when moving to Java. </p>
<p>The environment is a whole other issue all together. The Blackberry IDE is simply horrible. The look reminds me Borland C++ for Windows 3.1 - it's that outdated. Some of the other issues included spotty intellisense, weak debugging, etc... Blackberry does have a beta of the Eclipse plugin, but without debugging support, it's just an editor with fancy refactoring tools.</p>
<p>So, any advice on how to blend in to Java-ME?</p>

<p>How to center text over an image in a table cell using javascript, css, and/or html?</p>
<p>I have an HTML table containing images - all the same size - and I want to center a text label over each image. The text in the labels may vary in size. Horizontal centering is not difficult, but vertical centering is.</p>
<p>ADDENDUM: i did end up having to use javascript to center the text reliably using a fixed-size div with absolute positioning; i just could not get it to work any other way</p>

<p>Without getting a degree in information retrieval, I'd like to know if there exists any algorithms for counting the frequency that words occur in a given body of text. The goal is to get a "general feel" of what people are saying over a set of textual comments. Along the lines of <a href="http://wordle.net/" rel="noreferrer">Wordle</a>.</p>
<p>What I'd like:</p>
<ul>
<li>ignore articles, pronouns, etc ('a', 'an', 'the', 'him', 'them' etc)</li>
<li>preserve proper nouns</li>
<li>ignore hyphenation, except for soft kind</li>
</ul>
<p>Reaching for the stars, these would be peachy:</p>
<ul>
<li>handling stemming & plurals (e.g. like, likes, liked, liking match the same result)</li>
<li>grouping of adjectives (adverbs, etc) with their subjects ("great service" as opposed to "great", "service")</li>
</ul>
<p>I've attempted some basic stuff using Wordnet but I'm just tweaking things blindly and hoping it works for my specific data. Something more generic would be great.</p>

<p>How to implement a web page that scales when the browser window is resized?</p>
<p>I can lay out the elements of the page using either a table or CSS float sections, but i want the display to rescale when the browser window is resized</p>
<p>i have a working solution using AJAX PRO and DIVs with overflow:auto and an onwindowresize hook, but it is cumbersome. Is there a better way?</p>
<ul>
<li><p>thanks everyone for the answers so far, i intend to try them all (or at least most of them) and then choose the best solution as the answer to this thread</p></li>
<li><p>using CSS and percentages seems to work best, which is what I did in the original solution; using a visibility:hidden div set to 100% by 100% gives a way to measure the client area of the window [difficult in IE otherwise], and an onwindowresize javascript function lets the AJAXPRO methods kick in when the window is resized to redraw the layout-cell contents at the new resolution</p></li>
</ul>
<p>EDIT: my apologies for not being completely clear; i needed a 'liquid layout' where the major elements ('panes') would scale as the browser window was resized. I found that i had to use an AJAX call to re-display the 'pane' contents after resizing, and keep overflow:auto turned on to avoid scrolling</p>

<p>I'm trying to find a way to fake the result of a method called from within another method.</p>
<p>I have a "LoadData" method which calls a separate helper to get some data and then it will transform it (I'm interested in testing the transformed result).</p>
<p>So I have code like this:</p>
<pre><code>public class MyClass(){
public void LoadData(){
SomeProperty = Helper.GetSomeData();
}
public object SomeProperty {get;set;}
}
</code></pre>
<p>I want to have a known result from the Helper.GetSomeData() method. Can I use a mocking framework (I've got fairly limited experience with Rhino Mocks but am open to anything) to force an expected result? If so, how?</p>
<p>*Edit - yeah as expected I couldn't achieve the hack I wanted, I'll have to work out a better way to set up the data.</p>

<p>I'm a CompSci student, and fairly new at C#, and I was doing a "Josephus Problem" program for a class, and I created an Exit button that calls Application.Exit() to exit at anytime, but if C# is still working on painting and the button is pressed it throws an ObjectDisposedExeception for the Graphics object. Is there any way to prevent this?. I was thinking of try{}catch or change a boolean to tell the painting process to stop before exiting, but I want to know if there's another solution.</p>

<p>Is it possible to get a thread dump of a Java Web Start application? And if so, how?</p>
<p>It would be nice if there were a simple solution, which would enable a non-developer (customer) to create a thread dump. Alternatively, is it possible to create a thread dump programmatically?</p>
<p>In the Java Web Start Console I can get a list of threads by pressing 't' but stacktraces are not included.</p>
<p>If answers require certain java versions, please say so.</p>

<p>I have tree control object created using CTreeCtrl MFC class. The tree control needs to support rename.
When I left click on any of item in Tree the TVN_SELCHANGED event is called from which I can get the selected item of the tree as below :
HTREEITEM h = m_moveListTree.GetSelectedItem();
CString s = m_moveListTree.GetItemText(h);</p>
<p>However when I rightclick on any item in tree I do not get any TVN_SELCHANGED event and hence my selected item still remains the same from left click event. This is causing following problem :
1)User leftclicks on item A
2)user right clicks on item B and says rename
3)Since the selected item is still A the rename is applying for item A.</p>
<p>Please help in solving problem.</p>

<p>GNU/Linux text console, X11 not involved, indeed not even
installed. Keyboard is US layout, keymap US default. Kernel
version 2.20.x or later.</p>
<p>An application written in C is getting keyboard input in
translation mode, i.e. <code>XLATE</code> or <code>UNICODE</code>. When a key is
pressed, the application receives the corresponding
keystring. As an example, you press F1, the application
reads <code>"\033[[A"</code>.</p>
<p>Before the kernel sends the keystring to the application, it
must know which key is pressed, i.e. it must know its
scancode. In the F1 example above, the scancode for the key
pressed is 59 or 0x3b.</p>
<p>That's to say even when the keyboard is in translation mode,
the scancodes are held somewhere in memory. How can the
application access them without switching the keyboard to
<code>RAW</code> or <code>MEDIUMRAW</code> mode? A code snippet would help.</p>

<p>i've created a Form Panel, and i'm rendering couple of Combo Boxes in the panel with a store which is populated via an response handler.
the problem if i want to render the panel again it renders the combo boxes without the store, though i'm re-constructing the panel.
i tried to debug to figure out the cause and surprisingly though for combo box the Store is null on calling - comboBox.setStore(store) it checks for the property (isRendered) and finds it to be true and hence doesn't add the store but just keep the existing store which is still null.</p>
<p>i've seen this problem in another scenaio where i had created a collapsible field set containing the Combobox, On minimize and maximize of the fieldset the store vanishes for the same reasons.</p>
<p>can someone please help me here, i'm completely struck here i tried various option but nothing works.</p>

<p>How do I get a list of the active IP-addresses, MAC-addresses and <a href="http://en.wikipedia.org/wiki/NetBIOS" rel="nofollow noreferrer">NetBIOS</a> names on the LAN?</p>
<p>I'd like to get NetBIOS name, IP and <a href="http://en.wikipedia.org/wiki/MAC_address" rel="nofollow noreferrer">MAC addresses</a> for every host on the LAN, preferably not having to walk to every single PC and take note of the stuff myself.</p>
<p>How to do that with <a href="http://en.wikipedia.org/wiki/Windows_Script_Host" rel="nofollow noreferrer">Windows Script Host</a>/PowerShell/whatever?</p>

<p>I'm currently using ImageMagick to determine the size of images uploaded to the website. By calling ImageMagick's "identify" on the command line it takes about 0.42 seconds to determine a 1MB JPEG's dimensions along with the fact that it's a JPEG. I find that a bit slow.</p>
<p>Using the Imagick PHP library is even slower as it attemps to load the whole 1MB in memory before doing any treatment to the image (in this case, simply determining its size and type).</p>
<p>Are there any solutions to speed up this process of determining which file type and which dimensions an arbitrary image file has? I can live with it only supporting JPEG and PNG. It's important to me that the file type is determined by looking at the file's headers and not simply the extension.</p>
<p><strong>Edit: The solution can be a command-line tool UNIX called by PHP, much like the way I'm using ImageMagick at the moment</strong></p>

<p>I have an exe file generated with py2exe. In the setup.py I specify an icon to be embedded in the exe:</p>
<pre><code>windows=[{'script': 'my_script.py','icon_resources': [(0, 'my_icon.ico')], ...
</code></pre>
<p>I tried loading the icon using:</p>
<pre><code>hinst = win32api.GetModuleHandle(None)
hicon = win32gui.LoadImage(hinst, 0, win32con.IMAGE_ICON, 0, 0, win32con.LR_DEFAULTSIZE)
</code></pre>
<p>But this produces an (very unspecific) error:<br>
<strong>pywintypes.error: (0, 'LoadImage', 'No error message is available')</strong><br>
<br>
If I try specifying 0 as a string</p>
<pre><code>hicon = win32gui.LoadImage(hinst, '0', win32con.IMAGE_ICON, 0, 0, win32con.LR_DEFAULTSIZE)
</code></pre>
<p>then I get the error:<br>
<strong>pywintypes.error: (1813, 'LoadImage', 'The specified resource type cannot be found in the image file.')</strong><br>
<br>So, what's the correct method/syntax to load the icon?<br>
<em>Also please notice that I don't use any GUI toolkit - just the Windows API via PyWin32.</em></p>

<p>In our application, we receive text files (<code>.txt</code>, <code>.csv</code>, etc.) from diverse sources. When reading, these files sometimes contain garbage, because the files where created in a different/unknown codepage.</p>
<p>Is there a way to (automatically) detect the codepage of a text file? </p>
<p>The <code>detectEncodingFromByteOrderMarks</code>, on the <code>StreamReader</code> constructor, works for <code>UTF8</code> and other unicode marked files, but I'm looking for a way to detect code pages, like <code>ibm850</code>, <code>windows1252</code>. </p>
<hr>
<p>Thanks for your answers, this is what I've done.</p>
<p>The files we receive are from end-users, they do not have a clue about codepages. The receivers are also end-users, by now this is what they know about codepages: Codepages exist, and are annoying.</p>
<p><strong>Solution:</strong> </p>
<ul>
<li>Open the received file in Notepad, look at a garbled piece of text. If somebody is called François or something, with your human intelligence you can guess this.</li>
<li>I've created a small app that the user can use to open the file with, and enter a text that user knows it will appear in the file, when the correct codepage is used. </li>
<li>Loop through all codepages, and display the ones that give a solution with the user provided text. </li>
<li>If more as one codepage pops up, ask the user to specify more text.</li>
</ul>

<p>I'd like to offer my users correct links to an upgraded version of my program based on what platform they're running on, so I need to know whether I'm currently running on an x86 OS or an x64 OS.</p>
<p>The best I've found is using <code>Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE")</code>, but I would think there would be some built-in facility for this?</p>

<p>Continuing from my <a href="https://stackoverflow.com/questions/90751/double-and-floats-in-c">previous question</a>, is there a comprehensive document that lists all available differences between debug and release modes in a C# application, and particularly in a web application?</p>
<p>What differences are there?</p>

<p>I want to make an entity that has an autogenerated primary key, but also a unique compound key made up of two other fields. How do I do this in JPA?<br>
I want to do this because the primary key should be used as foreign key in another table and making it compound would not be good.</p>
<p>In the following snippet, I need the command and model to be unique. pk is of course the primary key.</p>
<pre><code>@Entity
@Table(name = "dm_action_plan")
public class ActionPlan {
@Id
private int pk;
@Column(name = "command", nullable = false)
private String command;
@Column(name = "model", nullable = false)
String model;
}
</code></pre>

<p>Is there a way to control the Fujitsu Softune debugger with an other application(e.g. Eclipse)? I think about sending the command mentioned in the documentation of Softune and parse the output, but also other approaches are welcome.</p>

<p>How can I get all items from a specific calendar (for a specific date).
Lets say for instance that I have a calendar with a recurring item every Monday evening. When I request all items like this:</p>
<pre><code>CalendarItems = CalendarFolder.Items;
CalendarItems.IncludeRecurrences = true;
</code></pre>
<p>I only get 1 item...</p>
<p>Is there an easy way to get <strong>all</strong> items (main item + derived items) from a calendar?
In my specific situation it can be possible to set a date limit but it would be cool just to get all items (my recurring items are time limited themselves).</p>
<p><strong>I'm using the Microsoft Outlook 12 Object library (Microsoft.Office.Interop.Outlook)</strong>.</p>

<p>I would like to know what would be the best way to do unit testing of a servlet. </p>
<p>Testing internal methods is not a problem as long as they don't refer to the servlet context, but what about testing the doGet/doPost methods as well as the internal method that refer to the context or make use of session parameters?</p>
<p>Is there a way to do this simply using classical tools such as JUnit, or preferrably TestNG? Did I need to embed a tomcat server or something like that?</p>

<p>I'm writing the memory manager for an application, as part of a team of twenty-odd coders. We're running out of memory quota and we need to be able to see what's going on, since we only appear to be using about 700Mb. I need to be able to report where it's all going - fragmentation etc. Any ideas?</p>

<p>Let's say I have a class:</p>
<pre><code>class Foo
{
public string Bar
{
get { ... }
}
public string this[int index]
{
get { ... }
}
}
</code></pre>
<p>I can bind to these two properties using "{Binding Path=Bar}" and "{Binding Path=[x]}". Fine.</p>
<p>Now let's say I want to implement INotifyPropertyChanged:</p>
<pre><code>class Foo : INotifyPropertyChanged
{
public string Bar
{
get { ... }
set
{
...
if( PropertyChanged != null )
{
PropertyChanged( this, new PropertyChangedEventArgs( "Bar" ) );
}
}
}
public string this[int index]
{
get { ... }
set
{
...
if( PropertyChanged != null )
{
PropertyChanged( this, new PropertyChangedEventArgs( "????" ) );
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
</code></pre>
<p>What goes in the part marked ????? (I've tried string.Format("[{0}]", index) and it doesn't work). Is this a bug in WPF, is there an alternative syntax, or is it simply that INotifyPropertyChanged isn't as powerful as normal binding?</p>

<p>Emacs Lisp has <code>replace-string</code> but has no <code>replace-char</code>. I want to replace "typographic" curly quotes (Emacs code for this character is hexadecimal 53979) with regular ASCII quotes, and I can do so with:</p>
<pre><code>(replace-string (make-string 1 ?\x53979) "'")
</code></pre>
<p>I think it would be better with <code>replace-char</code>. </p>
<p>What is the best way to do this?</p>

<p>I'm looking for a good, clean way to go around the fact that PHP5 still doesn't support multiple inheritance. Here's the class hierarchy:</p>
<p>Message<br>
-- TextMessage<br>
-------- InvitationTextMessage<br>
-- EmailMessage<br>
-------- InvitationEmailMessage </p>
<p>The two types of Invitation* classes have a lot in common; i'd love to have a common parent class, Invitation, that they both would inherit from. Unfortunately, they also have a lot in common with their current ancestors... TextMessage and EmailMessage. Classical desire for multiple inheritance here. </p>
<p>What's the most light-weight approach to solve the issue? </p>
<p>Thanks!</p>

<p>Using eclipse 3.3.2 with MyEclipse installed. For some reason if a file isn't called build.xml then it isnt' recognised as an ant file. The file association for *.xml includes ant and says "locked by 'Ant Buildfile' content type.</p>
<p>The run-as menu is broken. Even if the editor association works run-as doesn't.</p>
<p>The ant buildfiles in question are correctly formatted. They work fine if you call them build.xml or if you use them anywhere else. Eclipse just won't recognise and thus wont allow you to run them.</p>

<li>mydomain.com/specificPage -> newdomain.com/newSpecificPage</li>
<li>mydomain.com/anyOtherPage -> mydomain.com/anyOtherPage (no redirect here)</li>

<p>How can I do that on a JBoss server ?</p>

<p>I'm using this formula to calculate the distance between entries in my (My)SQL database which have latitude and longitude fields in decimal format:</p>
<pre><code>6371 * ACOS(SIN(RADIANS( %lat1% )) * SIN(RADIANS( %lat2% )) +
COS(RADIANS( %lat1% )) * COS(RADIANS( %lat2% )) * COS(RADIANS( %lon2% ) -
RADIANS( %lon1% )))
</code></pre>
<p>Substituting %lat1% and %lat2% appropriately it can be used in the WHERE clause to find entries within a certain radius of another entry, using it in the ORDER BY clause together with LIMIT will find the nearest x entries etc.</p>
<p>I'm writing this mostly as a note for myself, but improvements are always welcome. :)</p>
<p>Note: As mentioned by Valerion below, this calculates in kilometers. Substitute 6371 by an <a href="http://en.wikipedia.org/wiki/Earth_radius" rel="nofollow noreferrer">appropriate alternative number</a> to use meters, miles etc.</p>

<p>I want to verify a drag & drop operation is allowed. A valid item can come from another one of our "controls", or internally from within the custom treeview. Currently I have this:</p>
<pre><code>bool CanDrop(DragEventArgs e)
{
bool allow = false;
Point point = tree.PointToClient(new Point(e.X, e.Y));
TreeNode target = tree.GetNodeAt(point);
if (target != null)
{
if (CanWrite(target)) //user permissions
{
if (e.Data.GetData(typeof(DataInfoObject)) != null) //from internal application
{
DataInfoObject info = (DataInfoObject)e.Data.GetData(typeof(DataInfoObject));
DragDataCollection data = info.GetData(typeof(DragDataCollection)) as DragDataCollection;
if (data != null)
{
allow = true;
}
}
else if (tree.SelectedNode.Tag.GetType() != typeof(TreeRow)) //node belongs to this & not a root node
{
if (TargetExistsInNode(tree.SelectedNode, target) == false)
{
if (e.Effect == DragDropEffects.Copy)
{
allow = true;
}
else if (e.Effect == DragDropEffects.Move)
{
allow = true;
}
}
}
}
}
return allow;
}
</code></pre>
<p>I've moved all the checking code to this method to try to improve things, but to me this is still horrible!</p>
<p>So much logic, and so much of it to do things that I'd expect the treeview would do itself (eg. "TargetExistsInNode" checks whether the dragged node is being dragged to one of its children).</p>
<p>What is the best way to validate input to a control?</p>

<p>I've been thinking about this object oriented design question for a while now and have unable to come up with a satisfactory solution, so thought I'd throw it open to the crowds here for some opinions.</p>
<p>I have a <em>Game</em> class that represents a turn based board game, we can assume it's similar to Monopoly for the purposes of this question.
In my design I have a <em>Player</em> class containing a method <em>TakeTurn</em>.</p>
<p>The <em>Game</em> loops through all <em>Player</em>s and calls the TakeTurn method to do all the necessary things to complete the turn.
I want to be able to have n number of players, and be able to set an arbitrary number of them to be computer players.
So, my thought was to have a HumanPlayer class and a <em>ComputerPlayer</em> class, both of which derive from Player.</p>
<p>The <em>Game</em> knows only the <em>Player</em> class and simply calls the <em>TakeTurn</em> method on each <em>Player</em> in turn.
My problem comes in the fact that <em>ComputerPlayer</em> objects can be completely automated, i.e. keeping with the Monopoly example, can decide to buy a property using some piece of logic.
Now, with the <em>HumanPlayer</em> object, it needs to get an input from the actual user to be able to buy a property for instance, which seems to imply a different interface and potentially mean they shouldn't derive</p>
<p>I haven't been able to come up with a good solution to the problem without having the <em>Game</em> class know the actual implementations of the various <em>Player</em> classes explicitly.
I could always make the assumption in the <em>Game</em> class that there will only ever be human and computer players and effectively close it for extension, but it doesn't seem like good OO programming.</p>
<p>Any opinions on this would be appreciated.</p>

<p>So I log into a Solaris box, try to start Apache, and find that there is already a process listening on port 80, and it's not Apache. Our boxes don't have lsof installed, so I can't query with that. I guess I could do:</p>
<pre><code>pfiles `ls /proc` | less
</code></pre>
<p>and look for "port: 80", but if anyone has a better solution, I'm all ears! Even better if I can look for the listening process without being root. I'm open to both shell and C solutions; I wouldn't mind having a little custom executable to carry with me for the next time this comes up.</p>
<p>Updated: I'm talking about generic installs of solaris for which I am not the administrator (although I do have superuser access), so installing things from the freeware disk isn't an option. Obviously neither are using Linux-specific extensions to fuser, netstat, or other tools. So far running pfiles on <strong>all</strong> processes seems to be the best solution, unfortunately. If that remains the case, I'll probably post an answer with some slightly more efficient code that the clip above.</p>

<p>What options are there for building automated tests for GUIs written in Java Swing?</p>
<p>I'd like to test some GUIs which have been written using the <a href="http://www.netbeans.org/features/java/swing.html" rel="noreferrer">NetBeans Swing GUI Builder</a>, so something that works without requiring special tampering of the code under test would be ideal.</p>

<p>this is my first question to stackoverflow so here it goes...</p>
<p>I use cruise control for my continuous integration scheme, i want to use obfuscation in order to add another protection layer to my assemblies. The thing is that i don't know how to go about it since i couldn't find articles describing about this. Suggestions that include other CI tools such as NAnt are also accepted. </p>
<p>Commercial tools are also an option so don't hesitate to include them in your answer. The applications that i am building and want to obfuscate are mostly written in Compact Framework 2.0, Dot Net 2.0-3.5.</p>
<p>At the moment cruise control checks for changes in the repository, then based on the script for the specific solution downloads and builds the project by using devenv, after the setup project has been run it copies the setup file into a different folder and thats more or less it. So i need obfuscate somewhere in this process..</p>

<p>I'm trying to draw a polygon using c# and directx</p>
<p>All I get is an ordered list of points from a file and I need to draw the flat polygon in a 3d world.</p>
<p>I can load the points and draw a convex shape using a trianglefan and drawuserprimitives.</p>
<p>This obviously leads to incorrect results when the polygon is very concave (which it may be).</p>
<p>I can't imagine I'm the only person to grapple with this problem (tho I'm a gfx/directx neophyte - my background is in gui\windows application development). </p>
<p>Can anyone point me towards a simple to follow resource\tutorial\algorithm which may assist me?</p>

<p>Part of the install for an app I am responsible for, compiles some C code libraries. This is done in a console using GNU Make.</p>
<p>So, as part of the install, a console window pops open, you see the make file output wiz by as it compiles and links, when finished the console window closes and the installer continues.</p>
<p>All good, unless there is a compilation error. Then the make file bugs out and the console window closes before you have a chance to figure out what is happening.</p>
<p>So, what I'd like to happen is have the console window pause with a 'press a key to continue' type functionality, if there is an error from the makefile so that the console stays open. Otherwise, just exit as normal and close the console.</p>
<p>I can't work out how to do this in a GNU Makefile or from a batch file that could run the Make. </p>

<p>I'm writing a small tool in C# which will need to send and receive data to/from a website using POST and json formatting. I've never done anything like this before in C# (or any language really) so I'm struggling to find some useful information to get me started.</p>
<p>I've found some information on the WebRequest class in C# (specifically from <a href="http://msdn.microsoft.com/en-us/library/debx8sh9.aspx" rel="noreferrer">here</a>) but before I start diving into it, I wondered if this was the right tool for the job.</p>
<p>I've found plenty of tools to convert data into the json format but not much else, so any information would be really helpful here in case I end up down a dead end.</p>

<p>I have a migration that runs an SQL script to create a new Postgres schema. When creating a new database in Postgres by default it creates a schema called 'public', which is the main schema we use. The migration to create the new database schema seems to be working fine, however the problem occurs after the migration has run, when rails tries to update the 'schema_info' table that it relies on it says that it does not exist, as if it is looking for it in the new database schema and not the default 'public' schema where the table actually is.</p>
<p>Does anybody know how I can tell rails to look at the 'public' schema for this table?</p>
<p>Example of SQL being executed: ~</p>
<pre><code>CREATE SCHEMA new_schema;
COMMENT ON SCHEMA new_schema IS 'this is the new Postgres database schema to sit along side the "public" schema';
-- various tables, triggers and functions created in new_schema
</code></pre>
<p>Error being thrown: ~</p>
<pre><code>RuntimeError: ERROR C42P01 Mrelation "schema_info" does not exist
L221 RRangeVarGetRelid: UPDATE schema_info SET version = ??
</code></pre>
<p>Thanks for your help</p>

<p>Coming from a Classic ASP background, I'm used to multiple forms on a page, but this clearly limited in a ASP.NET page.</p>
<p>However, I have a situation where I have a form that gathers input from the user, saves the data to a DB, and afterwards I want to render (and tweak the values of) a special form that posts to the PayPal website.</p>
<p>If the PayPal form's field values were static, there would be no problem, but since I want to manipulate the form server-side (to tweak the qty, desc, price fields etc) this <em>will</em> be a problem.</p>
<p>I was considering redirecting to a different page after writing to the DB, and I suspect this would work fairly well, but it's a bit of extra effort that may be unneccessary.</p>
<p>It has also been suggested to me that I could programmatically render a different form, depending on where in the cycle I am. That is, use a placeholder, and on Page_Load I would add a DB Form (complete with child controls) initially, and the PayPal form after a Postback.</p>
<p>This scenario has got to be a common one for you guys, so I'm looking for opinions advice and any relevant code samples if you have preferred approach.</p>
<p>I know I can get by, but this project is a learning vehicle so I want to adopt what passes for best practice.</p>

<p>Environment: HP laptop with Windows XP SP2</p>
<p>I had created some encrypted files using GnuPG (gpg) for Windows. Yesterday, my hard disk failed so I had reimage the hard disk. I have now reinstalled gpg and regenerated my keys using the same passphrase as earlier. But, I am now unable to decrypt the files. I get the following error:</p>
<pre>
C:\sureshr>gpg -a c:\sureshr\work\passwords.gpg
gpg: encrypted with 1024-bit ELG-E key, ID 279AB302, created 2008-07-21
"Suresh Ramaswamy (AAA) BBB"
gpg: decryption failed: secret key not available
C:\sureshr>gpg --list-keys
C:/Documents and Settings/sureshr/Application Data/gnupg\pubring.gpg
--------------------------------------------------------------------
pub 1024D/80059241 2008-07-21
uid Suresh Ramaswamy (AAA) BBB
sub 1024g/279AB302 2008-07-21
</pre>
<p>AAA = gpg comment <br>
BBB = my email address</p>
<p>I am sure that I am using the correct passphrase. What exactly does this error mean? How do I tell gpg where to find my secret key?</p>
<p>Thanks,</p>
<p>Suresh</p>

<p>I need to sum points on each level earned by a tree of users. Level 1 is the sum of users' points of the users 1 level below the user. Level 2 is the Level 1 points of the users 2 levels below the user, etc...</p>
<p>The calculation happens once a month on a non production server, no worries about performance.</p>
<p>What would the SQL look like to do it?</p>
<p>If you're confused, don't worry, I am as well!</p>
<p>User table:</p>
<pre><code>ID ParentID Points
1 0 230
2 1 150
3 0 80
4 1 110
5 4 54
6 4 342
Tree:
0
|---\
1 3
| \
2 4---
\ \
5 6
</code></pre>
<p>Output should be:</p>
<pre><code>ID Points Level1 Level2
1 230 150+110 150+110+54+342
2 150
3 80
4 110 54+342
5 54
6 342
</code></pre>
<p>SQL Server Syntax and functions preferably...</p>

<p>How can brackets be escaped in using <code>string.Format</code>?</p>
<p>For example:</p>
<pre><code>String val = "1,2,3"
String.Format(" foo {{0}}", val);
</code></pre>
<p>This example doesn't throw an exception, but it outputs the string <code>foo {0}</code>.</p>
<p>Is there a way to escape the brackets?</p>

<p>I have a virtual machine (VMware) with Mercury Quick Test Professional 9.2 installed. I have a script to test an application, written in VB.NET using the Infragistics library.</p>
<p>If I access this virtual machine using my laptop (using Remote Desktop), everything works fine, the script completes without a problem. My laptop runs XP, with Windows Classic theme.</p>
<p>If I access this virtual machine using another machine (using Remote Desktop), the script starts fine, but stops halfway through, without no error message from QTP, nothing. This machine runs XP, with Windows Classic theme.</p>
<p>One difference between the two setups is the size of the screen, the laptop is 1920x1280, other machine 1280x1024.</p>
<p>The step where the script stops involves checking a checkbox within an UltraWinGrid. The checkbox itself is displayed, is on the screen in both cases.</p>
<p>Has anyone had this problem before, or have any idea why the behaviour is different between the two machines?</p>
<p>Thanks.</p>

<p>Is there a way to debug or trace every JavaScript event in Internet Explorer 7?</p>
<p>I have a bug that prevents scrolling after text-selecting, and I have no idea which event or action creates the bug. I really want to see which events are being triggered when I move the mouse for example. </p>
<p>It's too much work to rewire the source and I kind of hoped there was something like a sniffer which shows me all the events that are triggered.</p>

<p>Something similar to this</p>
<pre class="lang-sh prettyprint-override"><code>if [ -e /some/dir/* ]; then echo "huzzah"; fi;
</code></pre>
<p>but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files).</p>

<p>I'm working on a large c++ system that is has been in development for a few years now. As part of an effort to improve the quality of the existing code we engaged on a large long-term refactoring project.</p>
<p>Do you know a good tool that can help me write unit tests in C++? Maybe something similar to Junit or Nunit?</p>
<p>Can anyone give some good advice on the methodology of writing unit tests for modules that were written without unit testing in mind?</p>

<p>JSON text (<a href="http://www.ietf.org/rfc/rfc4627.txt?number=4627" rel="noreferrer">RFC 4627</a>) has unambigious representation of objects, arrays, strings, numbers, Boolean values (literally <code>true</code> or <code>false</code>) and <code>null</code>. However, it has nothing defined for representing time information like date and time of day, which is very common in applications. What are the current methods in use to represent time in JSON given the constraints and grammar laid out in <a href="http://www.ietf.org/rfc/rfc4627.txt?number=4627" rel="noreferrer">RFC 4627</a>?</p>
<p>Note to respondents: The purpose of this question is to document the various methods known to be in circulation along with examples and relative pros and cons (ideally from field experience).</p>

<p>I have a static library written in C++ and I have a structure describing data format, i.e.<br></p>
<pre><code>struct Format{
long fmtId;
long dataChunkSize;
long headerSize;
Format(long, long, long);
bool operator==(Format const & other) const;
};
</code></pre>
<p>Some of data formats are widely used, like <code>{fmtId=0, dataChunkSize=128, headerSize=0}</code> and <code>{fmtId=0, dataChunkSize=256, headerSize=0}</code><br><br>
Some data structure classes receive format in constructor. I'd like to have some sort of shortcuts for those widely used formats, like a couple of global <code>Format</code> members <code>gFmt128, gFmt256</code> that I can pass by reference. I instantiate them in a .cpp file like </p>
<p><code>Format gFmt128(0, 128, 0);</code></p>
<p>and in .h there is</p>
<p><code>extern Format gFmt128;</code></p>
<p>also, I declare <code>Format const & Format::Fmt128(){return gFmt128;}</code> and try to use it in the main module.</p>
<p>But if I try and do it in the main module that uses the lib, the linker complains about unresolved external <code>gFmt128</code>.</p>
<p>How can I make my library 'export' those global vars, so I can use them from other modules?</p>

<p>I seem to recall reading about an Amazon S3-compatible test server that you could run on your own server for unit tests or whatever. However, I've just exhausted my patience looking for this with both Google and AWS. Does such a thing exist? If not, I think I'll write one.</p>
<p>Note: I'm asking about Amazon S3 (the storage system) rather than Amazon EC2 (cloud computing).</p>

<p>I keep running into this problem when debugging JSP pages in OpenNMS. The Jetty wiki talks about keepGenerated (<a href="http://docs.codehaus.org/display/JETTY/KeepGenerated" rel="nofollow noreferrer">http://docs.codehaus.org/display/JETTY/KeepGenerated</a>) in webdefault.xml but it seems unclear how this works in embedded setups.</p>

<p>I have a memory buffer corresponding to my screen resolution (1280x800 at 24-bits-per-pixel) that contains my screen contents at 24bpp. I want to convert this to 8-bpp (ie. Halftone color palette in Windows).
I currently do this:
1. Use CreateDIBSection to allocate a new 1280x800 24-bpp buffer and access it as a DC, as well as a plain memory buffer
2. Use memcpy to copy from my original buffer to this new buffer from step 1
3. Use BitBlt to let GDI perform the color conversion</p>
<p>I want to avoid the extra memcpy of step 2. To do this, I can think of two approaches:</p>
<p>a. Wrap my original mem buf in a DC to perform BitBlt directly from it</p>
<p>b. Write my own 24-bpp to 8-bpp color conversion. I can't find any info on how Windows implements this halftone color conversion. Besides even if I find out, I won't be using the accelerated features of GDI that BitBlt has access to.</p>
<p>So how do I do either (a) or (b)?</p>
<p>thanks!</p>

<p>Suppose I have a simple XHTML document that uses a custom namespace for attributes:</p>
<pre><code><html xmlns="..." xmlns:custom="http://www.example.com/ns">
...
<div class="foo" custom:attr="bla"/>
...
</html>
</code></pre>
<p>How do I match each element that has a certain custom attribute using jQuery? Using</p>
<pre><code>$("div[custom:attr]")
</code></pre>
<p>does not work. (Tried with Firefox only, so far.)</p>

<p>I'm building a project using a GNU tool chain and everything works fine until I get to linking it, where the linker complains that it is missing/can't find <code>crti.o</code>. This is not one of my object files, it seems to be related to libc but I can't understand why it would need this <code>crti.o</code>, wouldn't it use a library file, e.g. <code>libc.a</code>?</p>
<p>I'm cross compiling for the arm platform. I have the file in the toolchain, but how do I get the linker to include it? </p>
<p><code>crti.o</code> is on one of the 'libraries' search path, but should it look for <code>.o</code> file on the library path? </p>
<p>Is the search path the same for <code>gcc</code> and <code>ld</code>?</p>

<p>I'm one of the people involved in the <a href="http://testanything.org/wiki/index.php/TAP_at_IETF:_Notes" rel="noreferrer">Test Anything Protocol (TAP) IETF group</a> (if interested, feel free to join the mailing list). Many programming languages are starting to adopt TAP as their primary testing protocol and they want more from it than what we currently offer. As a result, we'd like to get feedback from people who have a background in xUnit, TestNG or any other testing framework/methodology.</p>
<p>Basically, aside from a simple pass/fail, what information do you need from a test harness? Just to give you some examples:</p>
<ul>
<li>Filename and line number (if applicable) </li>
<li>Start and end time</li>
<li>Diagnostic output such as the difference between what you got and what you expected.</li>
</ul>
<p>And so on ...</p>

<p>I am looking for a tool that can take a unit test, like </p>
<pre><code>IPerson p = new Person();
p.Name = "Sklivvz";
Assert.AreEqual("Sklivvz", p.Name);
</code></pre>
<p>and generate, automatically, the corresponding stub class and interface</p>
<pre><code>interface IPerson // inferred from IPerson p = new Person();
{
string Name
{
get; // inferred from Assert.AreEqual("Sklivvz", p.Name);
set; // inferred from p.Name = "Sklivvz";
}
}
class Person: IPerson // inferred from IPerson p = new Person();
{
private string name; // inferred from p.Name = "Sklivvz";
public string Name // inferred from p.Name = "Sklivvz";
{
get
{
return name; // inferred from Assert.AreEqual("Sklivvz", p.Name);
}
set
{
name = value; // inferred from p.Name = "Sklivvz";
}
}
public Person() // inferred from IPerson p = new Person();
{
}
}
</code></pre>
<p>I know ReSharper and Visual Studio do some of these, but I need a complete tool -- command line or whatnot -- that automatically infers what needs to be done.
If there is no such tool, how would you write it (e.g. extending ReSharper, from scratch, using which libraries)?</p>

<p>In static languages like Java you need interfaces because
otherwise the type system just won't let you do certain things.
But in dynamic languages like PHP and Python you just take
advantage of <em>duck-typing</em>.</p>
<p>PHP supports interfaces.
Ruby and Python don't have them.
So you can clearly live happily without them.</p>
<p>I've been mostly doing my work in PHP and have never really
made use of the ability to define interfaces. When I need a
set of classes to implement certain common interface, then
I just describe it in documentation.</p>
<p>So, what do you think? Aren't you better off without using
interfaces in dynamic languages at all?</p>

<p>I would like to automatically increment a field named `incrementID' anytime any field in any row within the table named 'tb_users' is updated.
Currently I am doing it via the sql update statement.
i.e "UPDATE tb_users SET name = @name, incrementID = incrementID + 1 .....WHERE id = @id;</p>
<p>I'm wondering how I can do this automatically. for example, by changing the way sql server treats the field - kind of like the increment setting of 'Identity'.
Before I update a row, I wish to check whether the incrementID of the object to be updated is different to the incrementID of the row of the db.</p>

<p>I'm trying to match elements with a name that is <code>'container1$container2$chkChecked'</code>, using a regex of <code>'.+\$chkChecked'</code>, but I'm not getting the matches I expect when the element name is as described. What am I doing wrong?</p>

<p>I am considering using Postsharp framework to ease the burden of application method logging.
It basically allows me to adorn methods with logging attribute and at compile time injects the logging code needed into the il. I like this solution as it keeps the noise out of the deign time code environment.
Any thoughts, experiences or better alternatives?</p>

<p>In an application where users can belong to multiple groups, I'm currently storing their groups in a column called <code>groups</code> as a binary. Every four bytes is a 32 bit integer which is the <code>GroupID</code>. However, this means that to enumerate all the users in a group I have to programatically select all users, and manually find out if they contain that group.</p>
<p>Another method was to use a unicode string, where each character is the integer denoting a group, and this makes searching easy, but is a bit of a fudge.</p>
<p>Another method is to create a separate table, linking users to groups. One column called <code>UserID</code> and another called <code>GroupID</code>.</p>
<p>Which of these ways would be the best to do it? Or is there a better way?</p>

<p>Can anyone recommend a framework for templating/formatting messages in a standalone application along the lines of the JSP EL (Expression Language)?</p>
<p>I would expect to be able to instantiate a an object of some sort, give it a template along the lines of</p>
<pre><code>Dear ${customer.firstName}. You order will be dispatched on ${order.estimatedDispatchDate}
</code></pre>
<p>provide it with a context which would include a value dictionary of parameter objects (in this case an object of type Customer with a name 'customer', say, and an object of type Order with a name 'order').</p>
<p>I know there are many template frameworks out there - many of which work outside the web application context, but I do not see this as a big heavyweight templating framework. Just a better version of the basic Message Format functionality Java already provides </p>
<p>For example, I can accomplish the above with java.text.MessageFormat by using a template (or a 'pattern' as they call it) such as</p>
<pre><code>Dear {0}. You order will be dispatched on {1,date,EEE dd MMM yyyy}
</code></pre>
<p>and I can pass it an Object array, in my calling Java program</p>
<pre><code>new Object[] { customer.getFirstName(), order.getEstimatedDispatchDate() };
</code></pre>
<p>However, in this usage, the code and the pattern are intimately linked. While I could put the pattern in a resource properties file, the code and the pattern need to know intimate details about each other. With an EL-like system, the contract between the code and the pattern would be at a much higher level (e.g. customer and order, rather then customer.firstName and order.estimatedDispatchDate), making it easier to change the structure, order and contents of the message without changing any code.</p>
