<p>Is it possible to get a breakdown of CPU utilization <strong>by database</strong>?</p>
<p>I'm ideally looking for a Task Manager type interface for SQL server, but instead of looking at the CPU utilization of each PID (like <code>taskmgr</code>) or each SPID (like <code>spwho2k5</code>), I want to view the total CPU utilization of each database. Assume a single SQL instance.</p>
<p>I realize that tools could be written to collect this data and report on it, but I'm wondering if there is any tool that lets me see a live view of which databases are contributing most to the <code>sqlservr.exe</code> CPU load.</p>

<p>Watching SO come online has been quite an education for me. I'd like to make a checklist of various vunerabilities and exploits used against web sites, and what programming techniques can be used to defend against them.</p>
<ul>
<li>What categories of vunerabilities?
<ul>
<li>crashing site</li>
<li>breaking into server</li>
<li>breaking into other people's logins</li>
<li>spam</li>
<li><a href="http://en.wikipedia.org/wiki/Internet_sock_puppet" rel="nofollow noreferrer">sockpuppeting</a>, <a href="http://en.wikipedia.org/wiki/Internet_sock_puppet#Meatpuppet" rel="nofollow noreferrer">meatpuppeting</a></li>
<li>etc...</li>
</ul></li>
<li>What kind of defensive programming techniques?</li>
<li>etc...</li>

<p>I've followed the <a href="http://incubator.apache.org/couchdb/index.html" rel="noreferrer">CouchDB</a> project with interest over the last couple of years, and see it is now an Apache Incubator project. Prior to that, the CouchDB web site was full of <em>do not use for production code</em> type disclaimers, so I'd done no more than keep an eye on it. I'd be interested to know your experiences if you've been using CouchDB either for a live project, or a technology pilot. </p>

<p>Sometimes I need to quickly extract some arbitrary data from XML files to put into a CSV format. What's your best practices for doing this in the Unix terminal? I would love some code examples, so for instance how can I get the following problem solved?</p>
<p>Example XML input:</p>
<pre class="lang-html prettyprint-override"><code><root>
<myel name="Foo" />
<myel name="Bar" />
</root>
</code></pre>
<p>My desired CSV output:</p>
<pre><code>Foo,
Bar,
</code></pre>

<p>I have one table "orders" with a foreing key "ProductID".</p>
<p>I want to show the orders in a grid with the <strong>product name</strong>, without <strong>LazyLoad</strong> for better performance, but I if use <strong>DataLoadOptions</strong> it retrieves <strong>all</strong> Product fields, which seams like a <strong>overkill</strong>.</p>
<p>Is there a way to retrieve <strong>only</strong> the Product name in the first query?
Can I set some attribute in the DBML?</p>
<p>In this <a href="http://visualstudiomagazine.com/listings/list.aspx?id=566" rel="nofollow noreferrer">table</a> says that "Foreign-key values" are "Visible" in Linq To SQL, but don't know what this means.</p>
<p><strong>Edit</strong>: Changed the title, because I'm not really sure the there is no solution.<br>
Can't believe no one has the same problem, it is a very common scenario.</p>

<p>Notice the extra comma in the array declaration.
The code above gives different outputs for various browsers:</p>

<p>Firefox: 5</p>
<p>IE: 6</p>
<p>The extra comma in the array is being ignored by Safari and FF while IE treats it as another object in the array.</p>
<p>On some search, I have found mixed opinions about which answer is correct. Most people say that IE is correct but then Safari is also doing the same thing as Firefox. I haven't tested this on other browsers like Opera but I assume that there are discrepancies.</p>

<p>i. <strong>Which one of these is correct?</strong></p>
<p><em>Edit: By general consensus (and ECMAScript guidelines) we assume that IE is again at fault.</em> </p>
<p>ii. <strong>Are there any other such Javascript browser quirks that I should be wary of?</strong></p>
<p><em>Edit: Yes, there are loads of Javascript quirks. <a href="http://www.quirksmode.org" rel="nofollow noreferrer">www.quirksmode.org</a> is a good resource for the same.</em></p>
<p>iii. <strong>How do I avoid errors such as these?</strong></p>
<p><em>Edit: Use <a href="http://www.jslint.com/" rel="nofollow noreferrer">JSLint</a> to validate your javascript. Or, use some external <a href="http://openjsan.org/" rel="nofollow noreferrer">libraries</a>. Or, <a href="https://stackoverflow.com/questions/29053/javascript-browser-quirks-arraylength#29062">sanitize</a> your code.</em></p>

<p>When I try to use an <strong>ssh</strong> command in a shell script, the command just sits there. Do you have an example of how to use <strong>ssh</strong> in a shell script?</p>

<p>I have a repeater that is bound to some data.</p>
<p>I bind to the <strong>ItemDataBound</strong> event, and I am attempting to <strong>programmatically</strong> create a <strong>UserControl</strong>:</p>
<p>In a nutshell:</p>
<pre><code>void rptrTaskList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
CCTask task = (CCTask)e.Item.DataItem;
if (task is ExecTask)
{
ExecTaskControl foo = new ExecTaskControl();
e.Item.Controls.Add(foo);
}
}
</code></pre>
<p>The problem is that while the binding works, the user control is not rendered to the main page.</p>

<p>Since debate without meaningful terms is <a href="https://stackoverflow.com/questions/24270/whats-the-point-of-oop">meaningless</a>, I figured I would point at the elephant in the room and ask: What exactly makes a language "object-oriented"? I'm not looking for a textbook answer here, but one based on your experiences with OO languages that work well in your domain, whatever it may be.</p>
<p>A related question that might help to answer first is: What is the archetype of object-oriented languages and why?</p>

<p>Can anyone suggest a good implementation of a generic collection class that implements the <code>IBindingListView</code> & <code>IBindingList</code> interfaces and provides Filtering and Searching capabilities?</p>
<p>I see my current options as:<br /></p>
<ul>
<li>Using a class that someone else has written and tested</li>
<li>Inheriting from <code>BindingList<T></code>, and implementing the <code>IBindingListView</code> interfaces</li>
<li>Write a custom collection from scratch, implementing <code>IBindingListView</code> and <code>IBindingList</code>.</li>
</ul>
<p>Obviously, the first option is my preferred choice.</p>

<p>The problem: Loading an excel spreadsheet template. Using the Save command with a different filename and then quitting the interop object. This ends up saving the original template file. Not the result that is liked.</p>
<pre><code>public void saveAndExit(string filename)
{
excelApplication.Save(filename);
excelApplication.Quit();
}
</code></pre>
<p>Original file opened is c:\testing\template.xls
The file name that is passed in is c:\testing\7777 (date).xls</p>
<p>Does anyone have an answer?</p>
<p>(The answer I chose was the most correct and thorough though the wbk.Close() requires parameters passed to it. Thanks.)</p>

<p>This is a follow-on question to the <a href="https://stackoverflow.com/questions/29061/how-do-you-use-ssh-in-a-shell-script">How do you use ssh in a shell script?</a> question. If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return? When I try to just include the ampersand (&) at the end of the command it just hangs. The exact form of the command looks like this:</p>
<pre><code>ssh user@target "cd /some/directory; program-to-execute &"
</code></pre>
<p>Any ideas? One thing to note is that logins to the target machine always produce a text banner and I have <strong>SSH</strong> keys set up so no password is required.</p>

<p>I know that there are a few (automatic) ways to create a data access layer to manipulate an existing database (LINQ to SQL, Hibernate, etc...). But I'm getting kind of tired (and I believe that there should be a better way of doing things) of stuff like:</p>
<ol>
<li>Creating/altering tables in Visio</li>
<li>Using Visio's "Update Database" to create/alter the database</li>
<li>Importing the tables into a "LINQ to SQL classes" object</li>
<li>Changing the code accordingly</li>
<li>Compiling</li>
</ol>
<p>What about a way to generate the database schema from the objects/entities definition? I can't seem to find good references for tools like this (and I would expect some kind of built-in support in at least some frameworks).</p>
<p>It would be perfect if I could just:</p>
<ol>
<li>Change the object definition</li>
<li>Change the code that manipulates the object</li>
<li>Compile (the database changes are done auto-magically)</li>
</ol>

<p>My master branch layout is like this:</p>
<p><strong>/</strong> <-- top level</p>
<p><strong>/client</strong> <-- desktop client source files</p>
<p><strong>/server</strong> <-- Rails app</p>
<p>What I'd like to do is only pull down the /server directory in my <code>deploy.rb</code>, but I can't seem to find any way to do that. The /client directory is huge, so setting up a hook to copy /server to / won't work very well, it needs to only pull down the Rails app.</p>

<p>I'm using <a href="http://jquery.com/" rel="noreferrer">jQuery</a> and <a href="http://www.ericmmartin.com/projects/simplemodal/" rel="noreferrer">SimpleModal</a> in an ASP.Net project to make some nice dialogs for a web app. Unfortunately, any buttons in a modal dialog can no longer execute their postbacks, which is not really acceptable.</p>
<p>There is one source I've found with a <a href="http://blog.hurlman.com/post/jQuery2c-simpleModal2c-and-ASPNet-postbacks-do-not-play-well-together.aspx" rel="noreferrer">workaround</a>, but for the life of me I can't get it to work, mostly because I am not fully understanding all of the necessary steps.</p>
<p>I also have a workaround, which is to replace the postbacks, but it's ugly and probably not the most reliable. I would really like to make the postbacks work again. Any ideas?</p>
<p>UPDATE: I should clarify, the postbacks are not working because the Javascript used to execute the post backs has broken in some way, so nothing happens at all when the button is clicked.</p>

<p>I work a lot with network and serial communications software, so it is often necessary for me to have code to display or log hex dumps of data packets.</p>
<p>Every time I do this, I write yet another hex-dump routine from scratch. I'm about to do so again, but figured I'd ask here: Is there any good free hex dump code for C++ out there somewhere?</p>
<p>Features I'd like:</p>
<ul>
<li>N bytes per line (where N is somehow configurable)</li>
<li>optional ASCII/UTF8 dump alongside the hex</li>
<li>configurable indentation, per-line prefixes, per-line suffixes, etc.</li>
<li>minimal dependencies (ideally, I'd like the code to all be in a header file, or be a snippet I can just paste in)</li>
</ul>
<p><strong>Edit:</strong> Clarification: I am looking for code that I can easily drop in to my own programs to write to stderr, stdout, log files, or other such output streams. I'm not looking for a command-line hex dump utility.</p>

<p>Here is my sample code:</p>
<pre><code>from xml.dom.minidom import *
def make_xml():
doc = Document()
node = doc.createElement('foo')
node.innerText = 'bar'
doc.appendChild(node)
return doc
if __name__ == '__main__':
make_xml().writexml(sys.stdout)
</code></pre>
<p>when I run the above code I get this:</p>
<pre><code><?xml version="1.0" ?>
<foo/>
</code></pre>
<p>I would like to get:</p>
<pre><code><?xml version="1.0" ?>
<foo>bar</foo>
</code></pre>
<p>I just guessed that there was an innerText property, it gives no compiler error, but does not seem to work... how do I go about creating a text node?</p>

<p>I have the following HTML (note the CSS making the background black and text white)</p>
<pre><code><html>
<select id="opts" style="background-color: black; color: white;">
<option>first</option>
<option>second</option>
</select>
</html>
</code></pre>
<p>Safari is smart enough to make the small triangle that appears to the right of the text the same color as the foreground text.</p>
<p>Other browsers basically ignore the CSS, so they're fine too.</p>
<p>Firefox 3 however applies the background color but leaves the triangle black, so you can't see it, like this</p>
<p><img src="https://i.stack.imgur.com/Mvc7a.jpg" alt="Example"></p>
<p>I can't find out how to fix this - can anyone help? Is there a <code>-moz-select-triangle-color</code> or something obscure like that?</p>

<p>I was testing on a customer's box this afternoon which has Windows Vista (He had home, but I am testing on a Business Edition with same results).</p>
<p>We make use of a .DLL that gets the Hardware ID of the computer. It's usage is very simple and the sample program I have created works. The Dll is <a href="http://www.azsdk.com/hardwareid.html" rel="nofollow noreferrer">This from AzSdk</a>.
In fact, this works perfectly under Windows XP. However, for some strange reason, inside our project (way bigger), we get this exception: </p>
<pre><code>Exception Type: System.DllNotFoundException
Exception Message: Unable to load DLL 'HardwareID.dll': Invalid access to memory location. (Exception from HRESULT: 0x800703E6)
Exception Target Site: GetHardwareID
</code></pre>
<p>I don't know what can be causing the problem, since I have full control over the folder. The project is a c#.net Windows Forms application and everything works fine, except the call for the external library. </p>
<p>I am declaring it like this: (note: it's <em>not</em> a COM library and it doesn't need to be registered).</p>
<pre><code>[DllImport("HardwareID.dll")]
public static extern String GetHardwareID(bool HDD,
bool NIC, bool CPU, bool BIOS, string sRegistrationCode);
</code></pre>
<p>And then the calling code is quite simple:</p>
<pre><code>private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = GetHardwareID(cb_HDD.Checked,
cb_NIC.Checked,
cb_CPU.Checked,
cb_BIOS.Checked,
"*Registration Code*");
}
</code></pre>
<p>When you create a sample application, it works, but inside my projectit doesn't. Under XP works fine. Any ideas about what should I do in Vista to make this work?
As I've said, the folder and its sub-folders have Full Control for "Everybody". </p>
<p><strong>UPDATE:</strong> I do not have Vista SP 1 installed. </p>
<p><strong>UPDATE 2:</strong> I have installed Vista SP1 and now, with UAC disabled, not even the simple sample works!!! :( Damn Vista.</p>

<p>In the <a href="http://herdingcode.com/" rel="nofollow noreferrer">herding code</a> podcast 14 someone mentions that stackoverflow displayed the queries that were executed during a request at the bottom of the page. </p>
<p>It sounds like an excellent idea to me. Every time a page loads I want to know what sql statements are executed and also a count of the total number of DB round trips.
Does anyone have a neat solution to this problem? </p>
<p>What do you think is an acceptable number of queries? I was thinking that during development I might have my application throw an exception if more than 30 queries are required to render a page.</p>
<p>EDIT: I think I must not have explained my question clearly. During a HTTP request a web application might execute a dozen or more sql statements. I want to have those statements appended to the bottom of the page, along with a count of the number of statements.</p>
<p>HERE IS MY SOLUTION:</p>
<p>I created a TextWriter class that the DataContext can write to:</p>
<pre><code>public class Logger : StreamWriter
{
public string Buffer { get; private set; }
public int QueryCounter { get; private set; }
public Logger() : base(new MemoryStream())
{}
public override void Write(string value)
{
Buffer += value + "<br/><br/>";
if (!value.StartsWith("--")) QueryCounter++;
}
public override void WriteLine(string value)
{
Buffer += value + "<br/><br/>";
if (!value.StartsWith("--")) QueryCounter++;
}
}
</code></pre>
<p>In the DataContext's constructor I setup the logger:</p>
<pre><code>public HeraldDBDataContext()
: base(ConfigurationManager.ConnectionStrings["Herald"].ConnectionString, mappingSource)
{
Log = new Logger();
}
</code></pre>
<p>Finally, I use the <code>Application_OnEndRequest</code> event to add the results to the bottom of the page:</p>
<pre><code>protected void Application_OnEndRequest(Object sender, EventArgs e)
{
Logger logger = DataContextFactory.Context.Log as Logger;
Response.Write("Query count : " + logger.QueryCounter);
Response.Write("<br/><br/>");
Response.Write(logger.Buffer);
}
</code></pre>

<p>What is the most straightforward way to create a hash table (or associative array...) in Java? My google-fu has turned up a couple examples, but is there a standard way to do this?</p>
<p>And is there a way to populate the table with a list of key->value pairs without individually calling an add method on the object for each pair?</p>

<p>My current employer uses a 3rd party hosted CRM provider and we have a fairly sophisticated integration tier between the two systems. Amongst the capabilities of the CRM provider is for developers to author business logic in a Java like language and on events such as the user clicking a button or submitting a new account into the system, have validation and/or business logic fire off. </p>
<p>One of the capabilities that we make use of is for that business code running on the hosted provider to invoke web services that we host. The canonical example is a sales rep entering in a new sales lead and hitting a button to ping our systems to see if we can identify that new lead based on email address, company/first/last name, etc, and if so, return back an internal GUID that represents that individual. This all works for us fine, but we've run into a wall again and again in trying to setup a sane dev environment to work against.</p>
<p>So while our use case is a bit nuanced, this can generally apply to any development house that builds APIs for 3rd party consumption: <b>what are some best practices when designing a development pipeline and environment when you're building APIs to be consumed by the outside world?</b></p>
<p>At our office, all our devs are behind a firewall, so code in progress can't be hit by the outside world, in our case the CRM provider. We could poke holes in the firewall but that's less than ideal from a security surface area standpoint. Especially if the # of devs who need to be in a DMZ like area is high. We currently are trying a single dev machine in the DMZ and then remoting into it as needed to do dev work, but that's created a resource scarcity issue if multiple devs need the box, let alone they're making potentially conflicting changes (e.g. different branches).</p>
<p>We've considered just mocking/faking incoming requests by building fake clients for these services, but that's a pretty major overhead in building out feature sets (though it does by nature reinforce a testability of our APIs). This also doesn't obviate the fact that sometimes we really do need to diagnose/debug issues coming from the real client itself, not some faked request payload.</p>
<p>What have others done in these types of scenarios? In this day and age of mashups, there have to be a lot of folks out there w/ experiences of developing APIs--what's worked (and not worked so) well for the folks out there?</p>

<p>I have a web application that needs to read (and possibly write) files from a network share. I was wondering what the best way to do this would be?</p>
<p>I can't give the network service or aspnet accounts access to the network share. I could possibly use impersonation.</p>
<p>The network share and the web application are both hosted on the same domain and I can create a new user on the domain specifically for this purpose however I'm not quite sure how to join the dots between creating the filestream and specifying the credentials to use in the web application.</p>
<hr>
<p>Unfortunately the drive isn't mapped as a network drive on the machine, it's only available to me as a network share so unfortunately I can't make a transparent call.</p>
<p>There is one problem I can think of with impersonation... I can only impersonate one user per application domain I <em>think</em> but I'm happy to be corrected. I may need to write this file to several different shares which means I may have to impersonate several users.</p>
<p>I like the idea of creating a token... if I can do that I'll be able to ask the use up front for their credentials and then dynamically apply the security and give them meaningful error messages if access is denied... I'm off to play but I'll be back with an update.</p>

<p>Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to "true" and 0 turns to "false"? I could just use an if statement, but it would be nice to know if there is a way to do that with the language or standard libraries. Plus, I'm a pedant. :)</p>

<p>I'm using the .NET CF 3.5. The type I want to create does not have a default constructor so I want to pass a string to an overloaded constructor. How do I do this?</p>
<p>Code:</p>
<pre><code>Assembly a = Assembly.LoadFrom("my.dll");
Type t = a.GetType("type info here");
// All ok so far, assembly loads and I can get my type
string s = "Pass me to the constructor of Type t";
MyObj o = Activator.CreateInstance(t); // throws MissMethodException
</code></pre>

<p>I want to shift the contents of an array of bytes by 12-bit to the left.</p>
<p>For example, starting with this array of type <code>uint8_t shift[10]</code>:</p>
<pre><code>{0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0A, 0xBC}

<p>I'd like to shift it to the left by 12-bits resulting in:</p>

<p>I'd like to write a script/batch that will bunch up my daily IIS logs and zip them up by month.</p>
<p>ex080801.log which is in the format of ex<em>yymmdd</em>.log</p>
<p>ex080801.log - ex080831.log gets zipped up and the log files deleted.</p>
<p>The reason we do this is because on a heavy site a log file for one day could be 500mb to 1gb so we zip them up which compresses them by 98% and dump the real log file. We use webtrend to analyze the log files and it is capable of reading into a zip file.</p>
<p>Does anyone have any ideas on how to script this or would be willing to share some code?</p>

<p>In Ruby, trying to print out the individual elements of a String is giving me trouble. Instead of seeing each character, I'm seeing their ASCII values instead: </p>
<pre><code>>> a = "0123"
=> "0123"
>> a[0]
=> 48
</code></pre>
<p>I've looked online but can't find any way to get the original "0" back out of it. I'm a little new to Ruby to I know it has to be something simple but I just can't seem to find it.</p>

<p>I want to use CodeDOM to both declare and initialize my static field in one statement. How can I do this?</p>
<pre><code>// for example
public static int MyField = 5;
</code></pre>
<p>I can seem to figure out how to declare a static field, and I can set its value later, but I can't seem to get the above effect.</p>
<p>@lomaxx,
Naw, I just want static. I don't want const. This value can change. I just wanted the simplicity of declaring and init'ing in one fell swoop. As if anything in the codedom world is simple. Every type name is 20+ characters long and you end up building these huge expression trees. Makes my eyes bug out. I'm only alive today thanks to resharper's reformatting.</p>

<p>This might be on the "discussy" side, but I would really like to hear your view on this.</p>
<p>Previously I have often written data access classes that handled both reading and writing, which often led to poor naming, like FooIoHandler etc. The rule of thumb that classes that are hard to name probably are poorly designed suggests that this is not a good solution.</p>
<p>So, I have recently started splitting the data access into FooWriter and FooReader, which leads to nicer names and gives some additional flexibility, but at the same time I kind of like keeping it together, if the classes are not to big.</p>
<p>Is a reader/writer separation a better design, or should I combine them? If I should combine them, what the heck should I name the class?</p>
<p>Thanks /Erik</p>

<p>I wrote a quick program in python to add a gtk GUI to a cli program. I was wondering how I can create an installer using distutils. Since it's just a GUI frontend for a command line app it only works in *nix anyway so I'm not worried about it being cross platform.</p>
<p>my main goal is to create a .deb package for debian/ubuntu users, but I don't understand make/configure files. I've primarily been a web developer up until now.</p>
<p><strong>edit</strong>: Does anyone know of a project that uses distutils so I could see it in action and, you know, actually try building it?</p>
<h2>Here are a few useful links</h2>
<ul>
<li><p><a href="https://wiki.ubuntu.com/PackagingGuide/Python" rel="nofollow noreferrer">Ubuntu Python Packaging Guide</a></p>
<p>This Guide is <strong><em>very</em></strong> helpful. I don't know how I missed it during my initial wave of gooling. It even walks you through packaging up an existing python application</p></li>
<li><p><a href="https://wiki.ubuntu.com/MOTU/GettingStarted" rel="nofollow noreferrer">The Ubuntu MOTU Project</a></p>
<p>This is the official package maintaining project at ubuntu. Anyone can join, and there are lots of tutorials and info about creating packages, of all types, which include the above 'python packaging guide'.</p></li>
<li><p><a href="http://episteme.arstechnica.com/eve/forums/a/tpc/f/96509133/m/808004952931" rel="nofollow noreferrer">"Python distutils to deb?" - Ars Technica Forum discussion</a></p>
<p>According to this conversation, you can't just use distutils. It doesn't follow the debian packaging format (or something like that). I guess that's why you need dh_make as seen in the Ubuntu Packaging guide</p></li>
<li><p><a href="http://osdir.com/ml/linux.debian.devel.python/2004-10/msg00013.html" rel="nofollow noreferrer">"A bdist_deb command for distutils</a></p>
<p>This one has some interesting discussion (it's also how I found the ubuntu guide) about concatenating a zip-file and a shell script to create some kind of universal executable (anything with python and bash that is). weird. Let me know if anyone finds more info on this practice because I've never heard of it.</p></li>
<li><p><A href="http://mail.python.org/pipermail/distutils-sig/2000-May/001000.html" rel="nofollow noreferrer">Description of the deb format and how distutils fit in - python mailing list</a></p></li>

<p>It's one of those things that seems to have an odd curve where the more I think about it, the more it makes sense. To a certain extent, of course. And then it doesn't make sense to me at all.</p>
<p>Care to enlighten me?</p>

<p>I have a form element that contains multiple lines of inputs. Think of each line as attributes of a new object that I want to create in my web application. And, I want to be able to create multiple new objects in one HTTP POST. I'm using Javascript's built-in cloneNode(true) method to clone each line. The problem is that each input-line also has a removal link attached to its onclick-event:</p>
<pre><code>// prototype based
<div class="input-line">
<input .../>
<a href="#" onclick="$(this).up().remove();"> Remove </a>
</div>
</code></pre>
<p>When the cloned input-line's removal link is clicked, it also removes any input-lines that were cloned from the same dom object. Is it possible to rebind the "this" object to the proper anchor tag after using cloneNode(true) on the above DOM element?</p>

<p>In a VB.NET WinForms project, I get an exception</p>
<blockquote>
<p>Cannot access a disposed of object</p>
</blockquote>
<p>when closing a form. It occurs very rarely and I cannot recreate it on demand. The stack trace looks like this:</p>
<pre><code>Cannot access a disposed object. Object name: 'dbiSchedule'.
at System.Windows.Forms.Control.CreateHandle()
at System.Windows.Forms.Control.get_Handle()
at System.Windows.Forms.Control.PointToScreen(Point p)
at Dbi.WinControl.Schedule.dbiSchedule.a(Boolean A_0)
at Dbi.WinControl.Schedule.dbiSchedule.a(Object A_0, EventArgs A_1)
at System.Windows.Forms.Timer.OnTick(EventArgs e)
at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
</code></pre>
<p>The dbiSchedule is a schedule control from Dbi-tech. There is a timer on the form that updates the schedule on the screen every few minutes.</p>
<p>Any ideas what is causing the exception and how I might go about fixing it? or even just being able to recreate it on demand?</p>
<hr>
<p>Hej! Thanks for all the answers. We do stop the Timer on the FormClosing event and we do check the IsDisposed property on the schedule component before using it in the Timer Tick event but it doesn't help.</p>
<p>It's a really annoying problem because if someone did come up with a solution that worked - I wouldn't be able to confirm the solution because I cannot recreate the problem manually.</p>

<p>I've writen an Excel-based, database reporting tool. Currentely, all the VBA code is associated with a single XLS file. The user generates the report by clicking a button on the toolbar. Unfortunately, unless the user has saved the file under another file name, all the reported data gets wiped-out.</p>
<p>When I have created similar tools in Word, I can put all the code in a template (.dot) file and call it from there. If I put the template file in the Office startup folder, it will launch everytime I start Word. Is there a similar way, to package and distribute my code in Excel? I've tried using Add-ins, but I didn't find a way to call the code from the application window.</p>

<p>I have a few lines of PowerShell code that I would like to use as an automated script. The way I would like it to be able to work is to be able to call it using one of the following options:</p>
<ol>
<li>One command line that opens PowerShell, executes script and closes PowerShell (this would be used for a global build-routine)</li>
<li>A file that I can double-click to run the above (I would use this method when manually testing components of my build process)</li>
</ol>
<p>I have been going through PowerShell documentation online, and although I can find lots of scripts, I have been unable to find instructions on how to do what I need. Thanks for the help.</p>

<p>I'm developing a WinForms application (.Net 3.5, no WPF) where I want to be able to display foreign key lookups in a databound DataGridView. </p>
<p>An example of the sort of relationship is that I have a table of OrderLines. Orderlines have a foreign key relationship to Products and Products in turn have a foreign key relationship to ProductTypes. </p>
<p>I'd like to have a databound DataGridView where each row represents an orderline, displaying the line's product and producttype.</p>
<p>Users can add or edit orderlines direct to the grid and choose the product for the order line from a comboBoxColumn - this should then update the producttype column, showing the producttype for the selected product, in the same row.</p>
<p>The closest to a good fit that I've found so far is to introduce a domain object representing an orderline then bind the DataGridView to a collection of these orderlines. I then add properties to the orderline object that expose the product and the producttype, and raise relevant notifypropertychanged events to keep everything up to date. In my orderline repository I can then wire up the mappings between this orderline object and the three tables in my database.</p>
<p>This works for the databinding side of things, but having to hand code all that OR-mapping in the repository seems bad. I thought nHibernate would be able to help with this wiring up but am struggling with the mappings through all the foreign keys - they seem to work ok (the foreignkey lookup for an orderline's product creates the correct product object based on the foreign key) until I try to do the databinding, I can't get the databound id columns to update my product or producttype objects.</p>
<p>Is my general approach even in the right ballpark? If it is, what is a good solution to the mapping problem?</p>
<p>Or, is there a better solution to databinding rows including foreign key lookups that I haven't even considered?</p>

//some code
}
catch (SqlException ex)
{
if (ex.Message.Contains("Timeout"))
{
//handle timeout
}
else

throw;

<p>I have two machines in two different domains. On both I have VS 2005 installed. I want remote debug between them. Without authentication it is possible but I want to debug managed code. I don't want to debug directly since it is really crappy machine.</p>
<p>When I try to attach with debugger I get message "The trust relationship between this workstation and primary domain failed." Any idea how to overcome this ? I tried tricks with adding same local username on both machines but with no luck.</p>
<p>EDIT: I have same local users on both machines. I started both VS2005 and Debugging monitor with RunAs using local users. I turned Windows Auditing on debug machine and I see that local user from VS2005 machine is trying to logon. But he fails with error 0xC000018D (ERROR_TRUSTED_RELATIONSHIP_FAILURE)</p>

<p>I'll have an ASP.net page that creates some Excel Sheets and sends them to the user. The problem is, sometimes I get Http timeouts, presumably because the Request runs longer than executionTimeout (110 seconds per default).</p>
<p>I just wonder what my options are to prevent this, without wanting to generally increase the executionTimeout in <code>web.config</code>?</p>
<p>In PHP, <a href="http://fr.php.net/manual/en/function.set-time-limit.php" rel="nofollow noreferrer"><code>set_time_limit</code></a> exists which can be used in a function to extend its life, but I did not see anything like that in C#/ASP.net?</p>
<p>How do you handle long-running functions in ASP.net?</p>

<p>JAutodoc is what I was looking for. It has Ant tasks, an Eclipse plugin, and uses Velocity for the template definition.</p>

<pre><code>SELECT * FROM PEOPLE WHERE SURNAME='O'Keefe'

<p>I (understandably) get an error.</p>
<p>How do I prevent this error from occurring. I am using Oracle and PLSQL.</p>

<p>I am using jQuery and trying to find a cross browser way to get the pixel coordinates of the caret in <code><textarea></code>s and <code>input</code> boxes such that I can place an absolutely positioned div around this location.</p>
<p>Is there some jQuery plugin? Or JavaScript snippet to do just that?</p>

<p>I have done a bit of research into this and it seems that the only way to sort a data bound combo box is to sort the data source itself (a DataTable in a DataSet in this case). </p>
<p>If that is the case then the question becomes what is the best way to sort a DataTable?</p>
<p>The combo box bindings are set in the designer initialize using</p>
<p><pre><code>myCombo.DataSource = this.typedDataSet;
myCombo.DataMember = "Table1";
myCombo.DisplayMember = "ColumnB";
myCombo.ValueMember = "ColumnA";</pre></code></p>
<p>I have tried setting
<pre><code>this.typedDataSet.Table1.DefaultView.Sort = "ColumnB DESC";</pre></code>
But that makes no difference, I have tried setting this in the control constructor, before and after a typedDataSet.Merge call.</p>

<p>I'm looking for something that will show me the size of each folder within my main folder recursively.</p>
<p>This is a <a href="http://en.wikipedia.org/wiki/LAMP_%28software_bundle%29" rel="nofollow noreferrer">LAMP</a> server with a CGI-Bin so most any PHP script should work or anything that will work in the CGI-Bin.</p>
<p>My hosting company does not provide an interface for me to see which folders are consuming the most amount of space. I don't know of anything on the Internet and did a few searches however I came up with no results. </p>
<p>Something implementing graphs (<a href="http://en.wikipedia.org/wiki/GD_Graphics_Library" rel="nofollow noreferrer">GD</a>/<a href="http://en.wikipedia.org/wiki/ImageMagick" rel="nofollow noreferrer">ImageMagick</a>) would be best but not required.</p>
<p>My host supports only Perl in the CGI-BIN.</p>

<p>I am having problems submitting forms which contain UTF-8 strings with Ajax. I am developing a <a href="http://en.wikipedia.org/wiki/Apache_Struts" rel="noreferrer">Struts</a> web application which runs in a <a href="http://en.wikipedia.org/wiki/Apache_Tomcat" rel="noreferrer">Tomcat</a> server. This is the environment I set up to work with UTF-8:</p>
<ul>
<li><p>I have added the attributes <code>URIEncoding="UTF-8" useBodyEncodingForURI="true"</code> into the <code>Connector</code> tag to Tomcat's <code>conf/server.xml</code> file.</p></li>
<li><p>I have a <code>utf-8_general_ci</code> database</p></li>
<li><p>I am using the next filter to ensure my request and responses are encoded in UTF-8</p>
<pre><code>package filters;
import java.io.IOException;
import javax.servlet.*;
public class UTF8Filter implements Filter {
public void destroy() {}
public void doFilter(ServletRequest request,ServletResponse response, FilterChain chain)
throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
}
}
</code></pre></li>
<li><p>I use this filter in WEB-INF/web.xml</p></li>
<li><p>I am using the next code for my JSON responses:</p>
<pre><code>public static void populateWithJSON(HttpServletResponse response,JSONObject json)
{
String CONTENT_TYPE="text/x-json;charset=UTF-8";
response.setContentType(CONTENT_TYPE);
response.setHeader("Cache-Control", "no-cache");
try {
response.getWriter().write(json.toString());
} catch (IOException e) {
throw new ApplicationException("Application Exception raised in RetrievedStories", e);
}
}
</code></pre></li>
</ul>
<p>Everything seems to work fine (content coming from the database is displayed properly, and I am able to submit forms which are stored in UTF-8 in the database). The problem is that I am <strong>not able to submit forms with Ajax</strong>. I use jQuery, and I thought the problem was the lack of contentType field in the Ajax request. But I was wrong. I have a really simple form to submit comments which contains of an id and a body. The body field can be in different languages such as Spanish, German, or whatever.</p>
<p>If I submit my form with body textarea containing <code>contraseña</code>, <a href="http://en.wikipedia.org/wiki/Firebug_%28software%29" rel="noreferrer">Firebug</a> shows me:</p>
<blockquote>
<h3>Request Headers</h3>
<ul>
<li><strong><em>Host</em></strong> localhost:8080</li>
<li><strong><em>Accept-Charset</em></strong> ISO-8859-1, utf-8;q=0.7;*q=0.7</li>
<li><strong><em>Content-Type</em></strong> application/x-www-form-urlencoded; charset UTF-8</li>
</ul>
</blockquote>
<p>If I execute <em>Copy Location with parameters</em> in Firebug, the encoding seems already wrong:</p>
<pre><code>http://localhost:8080/Cerepedia/corporate/postStoryComment.do?&body=contrase%C3%B1a&id=88
</code></pre>
<p>This is my jQuery code:</p>
<pre><code>function addComment() {
var comment_body = $("#postCommentForm textarea").val();
var item_id = $("#postCommentForm input:hidden").val();
var url = rooturl+"corporate/postStoryComment.do?";
$.post(url, { id: item_id, body: comment_body } ,
function(data){
/* Do stuff with the answer */
}, "json"); }
</code></pre>
<p>A submission of a form with jQuery is causing the next error server side (note I am using <a href="http://en.wikipedia.org/wiki/Hibernate_%28Java%29" rel="noreferrer">Hibernate</a>).</p>

<p>I've got a problem here with an MSI deployment that I'm working on (using <a href="http://en.wikipedia.org/wiki/InstallShield" rel="nofollow noreferrer">InstallShield</a>). We have a program running in the background that needs to run per-user, and it needs to start automatically without user intervention.</p>
<p>The problem is with <a href="http://en.wikipedia.org/wiki/Group_Policy#Operation" rel="nofollow noreferrer">Group Policy Object</a>/<a href="http://en.wikipedia.org/wiki/Active_Directory" rel="nofollow noreferrer">Active Directory</a> (GPO/AD) deployment the application is started in the SYSTEM context before anyone is logged in rather than as the user who is about to log in. The application can only run once per user, and it seems that the SYSTEM process prevents the USER process from starting. This means the PCs need to be rebooted twice before the software can be deployed to the users. How do we to stop this?</p>
<p>Basically the current workflow is: </p>
<ol>
<li>Installation/upgrade runs... kill background application</li>
<li>Install new files</li>
<li>Startup background application</li>
</ol>
<p>This works for published applications and interactive <a href="http://en.wikipedia.org/wiki/Windows_Installer" rel="nofollow noreferrer">MSI</a> installations - it's only 'assigned' applications that seem to have the problem. As step 3 happens in the SYSTEM context rather than the user context :(</p>
<p>Ideally, I'd have the development team patch the EXE file to prevent launching in the SYSTEM context, but that's a release cycle away, and I'm looking for an installer-based solution for the interim.</p>
<p>(I don't know Installscript... So I'm guessing <a href="http://en.wikipedia.org/wiki/VBScript" rel="nofollow noreferrer">VBScript</a> is probably the way to go if there's no native InstallShield stuff I can use.)</p>

<p>Can anyone recommend a good repository viewer for Git, similar to gitk, that works on Mac OS X Leopard? (I'm not saying gitk doesn't work)</p>
<p>Of course I would like a native Mac application, but as I haven't found any, what are the best options to gitk?</p>
<p>I know about gitview, but I'm looking forward to evaluate as many alternatives as possible.</p>

<p>I am in charge of about 100+ documents (word document, not source code) that needs revision by different people in my department. Currently all the documents are in a shared folder where they will retrieve, revise and save back into the folder. </p>
<p>What I am doing now is looking up the "date modified" in the shared folder, opened up recent modified documents and use the "Track Change" function in MS Word to apply the changes. I find this a bit tedious.</p>
<p>So will it be better and easier if I commit this in a version control database?</p>
<p>Basically I want to keep different version of a file.</p>
<p><hr>
What have I learn from answers:</p>
<ul>
<li><p>Use Time Machine to save different
version (or Shadow copy in Vista)</p></li>
<li><p>There is a difference between text
and binary documents when you use
version control app. (I didn't know
that)</p></li>
<li><p>Diff won't work on binary files</p></li>
<li><p>A notification system (ie email) for revision is great</p></li>
<li><p>Google Docs revision feature.</p></li>
</ul>
<p><strong>Update</strong> : </p>
<p>I played around with Google Docs revision feature and feel that it is almost right for me. Just a bit annoyed with the too frequent versioning (autosaving). </p>
<p>But what feels right for me doesn't mean it feels right for my dept. Will they be okay with saving all these documents with Google? </p>

<p>In Java, say you have a class that wraps an <code>ArrayList</code> (or any collection) of objects. </p>
<p>How would you return one of those objects such that the caller will not see any future changes to the object made in the ArrayList? </p>
<p>i.e. you want to return a deep copy of the object, but you don't know if it is cloneable.</p>

<p>One of our weblogic 8.1s has suddenly started logging giant amounts of logs and filling the disk.</p>
<p>The logs giving us hassle resides in </p>
<pre><code>mydrive:\bea\weblogic81\common\nodemanager\NodeManagerLogs\generatedManagedServer1\managedserveroutput.log

<p>and the entries in the logfile is just the some kind of entries repeated again and again. Stuff like</p>

<p>I can't find any debug settings set anywhere.
I've looked in the Remote Start classpath and Arguments for the managed server.</p>
<p>Can anyone point me in the direction to gain control over this logfile?</p>

<p>We have a Windows Service written in C#. The service spawns a thread that does this: </p>
<pre><code>private void ThreadWorkerFunction()
{
while(false == _stop) // stop flag set by other thread
{
try
{
openConnection();
doStuff();
closeConnection();
}
catch (Exception ex)
{
log.Error("Something went wrong.", ex);
Thread.Sleep(TimeSpan.FromMinutes(10));
}
}
}
</code></pre>
<p>We put the Thread.Sleep in after a couple of times when the database had gone away and we came back to 3Gb logs files full of database connection errors. </p>
<p>This has been running fine for months, but recently we've seen a few instances where the log.Error() statement logs a "System.InvalidOperationException: This SqlTransaction has completed; it is no longer usable" exception and then never ever comes back. The service can be left running for days but nothing more will be logged.</p>
<p>Having done some reading I know that Thread.Sleep is not ideal, but why would it simply never come back?</p>

<p>I have an application on which I am implementing localization.</p>
<p>I now need to dynamically reference a name in the resouce file.</p>
<p>assume I have a resource file called Login.resx, an a number of strings: foo="hello", bar="cruel" and baz="world"</p>
<p>normally, I will refer as:
String result =Login.foo;
and result=="hello";</p>
<p>my problem is, that at code time, I do not know if I want to refer to foo, bar or baz - I have a string that contains either "foo", "bar" or "baz". </p>
<p>I need something like:</p>
<p>Login["foo"];</p>
<p>Does anyone know if there is any way to dynamically reference a string in a resource file?</p>

<p>I have a History Table in SQL Server that basically tracks an item through a process. The item has some fixed fields that don't change throughout the process, but has a few other fields including status and Id which increment as the steps of the process increase.</p>
<p>Basically I want to retrieve the last step for each item given a Batch Reference. So if I do a </p>
<pre><code>Select * from HistoryTable where BatchRef = @BatchRef
</code></pre>
<p>It will return all the steps for all the items in the batch - eg</p>
<pre>
<b>Id Status BatchRef ItemCount</b>
1 1 Batch001 100
1 2 Batch001 110
2 1 Batch001 60
2 2 Batch001 100
</pre>
<p>But what I really want is:</p>
<pre>
<b>Id Status BatchRef ItemCount</b>
1 2 Batch001 110
2 2 Batch001 100
</pre>
<p>Edit: Appologies - can't seem to get the TABLE tags to work with Markdown - followed the help to the letter, and looks fine in the preview</p>

<p>The default Python install on OS X 10.5 is 2.5.1 with a FAT 32 bit (Intel and PPC) client. I want to setup apache and mysql to run django. In the past, I have run Apache and MySQL to match this install in 32 bit mode (even stripping out the 64 bit stuff from Apache to make it work).</p>
<p>I want to upgrade Python to 64 bit. I am completely comfortable with compiling it from source with one caveat. How do I match the way that the default install is laid out? Especially, with regards to site-packages being in <code>/Library/Python/2.5/</code> and not the one in buried at the top of the framework once I compile it. </p>

<p>I need to match and remove all tags using a regular expression in Perl. I have the following:</p>
<pre><code><\\??(?!p).+?>
</code></pre>
<p>But this still matches with the closing <code></p></code> tag. Any hint on how to match with the closing tag as well?</p>
<p>Note, this is being performed on xhtml.</p>

<p>I'm writing a simple photo album app using ASP.NET Ajax.<br>
The app uses async Ajax calls to pre-load the next photo in the album, without changing the URL in the browser.</p>
<p>The problem is that when the user clicks the <strong>back</strong> button in the browser, the app doesn't go back to the previous photo, instead, it navigates to the home page of the application.</p>
<p>Is there a way to trick the browser into adding each Ajax call to the browsing history?</p>

<p>We have a couple of ASP.Net dataview column templates that are dynamically added to the dataview depending on columns selected by users.</p>
<p>These templated cells need to handle custom databindings:</p>
<pre><code>public class CustomColumnTemplate:
ITemplate
{
public void InstantiateIn( Control container )
{
//create a new label
Label contentLabel = new Label();
//add a custom data binding
contentLabel.DataBinding +=
( sender, e ) =>
{
//do custom stuff at databind time
contentLabel.Text = //bound content
};
//add the label to the cell
container.Controls.Add( contentLabel );
}
}
...
myGridView.Columns.Add( new TemplateField
{
ItemTemplate = new CustomColumnTemplate(),
HeaderText = "Custom column"
} );
</code></pre>
<p>Firstly this seems rather messy, but there is also a resource issue. The <code>Label</code> is generated, and can't be disposed in the <code>InstantiateIn</code> because then it wouldn't be there to databind.</p>
<p>Is there a better pattern for these controls? </p>
<p>Is there a way to make sure that the label is disposed after the databind and render?</p>

<p>So I'm working on some legacy code that's heavy on the manual database operations. I'm trying to maintain some semblance of quality here, so I'm going TDD as much as possible.</p>
<p>The code I'm working on needs to populate, let's say a <code>List<Foo></code> from a DataReader that returns all the fields required for a functioning Foo. However, if I want to verify that the code in fact returns one list item per one database row, I'm writing test code that looks something like this:</p>
<pre><code>Expect.Call(reader.Read()).Return(true);
Expect.Call(reader["foo_id"]).Return((long) 1);
// ....
Expect.Call(reader.Read()).Return(true);
Expect.Call(reader["foo_id"]).Return((long) 2);
// ....
Expect.Call(reader.Read()).Return(false);
</code></pre>
<p>Which is rather tedious and rather easily broken, too. </p>
<p>How should I be approaching this issue so that the result won't be a huge mess of brittle tests?</p>
<p>Btw I'm currently using Rhino.Mocks for this, but I can change it if the result is convincing enough. Just as long as the alternative isn't TypeMock, because their EULA was a bit too scary for my tastes last I checked.</p>
<p>Edit: I'm also currently limited to C# 2.</p>

<p>I'd like my program to be able to email me error reports. How can I do this without hard-coding a username/password/SMTP server/etc. into the code? (Doing so would allow users to decompile the program and take over this email account.)</p>
<p>I've been told you could do some stuff with telneting to port 25, but I'm very fuzzy on the details. Most of the code snippets on Google assume you have a preexisting account, which doesn't work in this situation.</p>
<p>I am using .NET v3.5 (C# in particular), but I would imagine the ideas are similar enough in most languages. As long as you realize I'm doing this for an offline app, and don't supply me with PHP code or something, we should be fine.</p>

<p>I have the following html code: </p>
<pre><code><h3 id="headerid"><span onclick="expandCollapse('headerid')">&uArr;</span>Header title</h3>
</code></pre>
<p>I would like to toggle between up arrow and down arrow each time the user clicks the span tag. </p>
<pre><code>function expandCollapse(id) {
var arrow = $("#"+id+" span").html(); // I have tried with .text() too
if(arrow == "&dArr;") {
$("#"+id+" span").html("&uArr;");
} else {
$("#"+id+" span").html("&dArr;");
}
}
</code></pre>
<p>My function is going always the else path. If I make a javacript:alert of <code>arrow</code> variable I am getting the html entity represented as an arrow. How can I tell jQuery to interpret the <code>arrow</code> variable as a string and not as html. </p>

<p>I've seen a lot of commonality in regex capabilities of different regex-enabled tools/languages (e.g. perl, sed, java, vim, etc), but I've also many differences.</p>
<p>Is there a <em>standard</em> subset of regex capabilities that all regex-enabled tools/languages will support? How do regex capabilities vary between tools/languages?</p>

<p>I got embroiled in a discussion about DOM implementation quirks yesterday, with gave rise to an interesting question regarding Text.splitText and Element.normalise behaviours, and how they should behave.</p>
<p>In <a href="http://www.w3.org/TR/1998/REC-DOM-Level-1-19981001/level-one-core.html" rel="nofollow noreferrer">DOM Level 1 Core</a>, Text.splitText is defined as...</p>
<blockquote>
<p>Breaks this Text node into two Text nodes at the specified offset, keeping both in the tree as siblings. This node then only contains all the content up to the offset point. And a new Text node, which is inserted as the next sibling of this node, contains all the content at and after the offset point.</p>
</blockquote>
<p>Normalise is...</p>
<blockquote>
<p>Puts all Text nodes in the full depth of the sub-tree underneath this Element into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.</p>
</blockquote>
<p>So, if I take a text node containing "Hello World", referenced in textNode, and do</p>
<pre><code>textNode.splitText(3)
</code></pre>
<p>textNode now has the content "Hello", and a new sibling containing " World"</p>
<p>If I then</p>
<pre><code>textNode.parent.normalize()
</code></pre>
<p><em>what is textNode</em>? The specification doesn't make it clear that textNode has to still be a child of it's previous parent, just updated to contain all adjacent text nodes (which are then removed). It seems to be to be a conforment behaviour to remove all the adjacent text nodes, and then recreate a new node with the concatenation of the values, leaving textNode pointing to something that is no longer part of the tree. Or, we can update textNode in the same fashion as in splitText, so it retains it's tree position, and gets a new value.</p>
<p>The choice of behaviour is really quite different, and I can't find a clarification on which is correct, or if this is simply an oversight in the specification (it doesn't seem to be clarified in levels 2 or 3). Can any DOM/XML gurus out there shed some light?</p>

<p>The <a href="http://developer.apple.com/documentation/AppleApplications/Reference/SafariWebContent/UsingiPhoneApplications/chapter_6_section_4.html" rel="nofollow noreferrer">Apple Developer Documentation</a> (link is dead now) explains that if you place a link in a web page and then click it whilst using Mobile Safari on the iPhone, the Google Maps application that is provided as standard with the iPhone will launch.</p>
<p>How can I launch the same Google Maps application with a specific address from within my own native iPhone application (i.e. not a web page through Mobile Safari) in the same way that tapping an address in Contacts launches the map?</p>
<p><strong>NOTE: THIS ONLY WORKS ON THE DEVICE ITSELF. NOT IN THE SIMULATOR.</strong></p>

<p>Yesterday I wanted to add a boolean field to an Oracle table. However, there isn't actually a boolean data type in Oracle. Does anyone here know the best way to simulate a boolean? Googling the subject discovered several approaches</p>
<ol>
<li><p>Use an integer and just don't bother assigning anything other than 0 or 1 to it.</p></li>
<li><p>Use a char field with 'Y' or 'N' as the only two values.</p></li>
<li><p>Use an enum with the CHECK constraint.</p></li>
</ol>
<p>Do experienced Oracle developers know which approach is preferred/canonical?</p>

<p>I'm looking for a way to redirect all the stderr streams in interactive bash (ideally to its calling parent process).</p>
<p>I don't want to redirect stderr stream from each individual command, which I could do by appending <code>2> a_file</code> to each command.</p>
<p>By default, these stderr streams are redirected to the stdout of an interactive bash. I would like to get them on the stderr of this interactive bash process in order to prevent my stdout to be polluted by error messages and be able to treat them separatly.</p>
<p>Any ideas?</p>
<p>I still haven't found an answer ... But maybe it's actually a tty parameter. Does anybody knows something about tty/interactive shell responsibility for handling stderr ?</p>

<p>We have several .NET applications that monitor a directory for new files, using FileSystemWatcher. The files are copied from another location, uploaded via FTP, etc. When they come in, the files are processed in one way or another. However, one problem that I have never seen a satisfactory answer for is: for large files, how does one know when the files being monitored are still being written to? Obviously, we need to wait until the files are complete and closed before we begin processing them. The event args in the FileSystemWatcher events do not seem to address this.</p>

<p>In my browsings amongst the Internet, I came across <a href="http://www.reddit.com/r/programming/comments/6y6lr/ask_proggit_which_is_more_useful_to_know_c_or_java/" rel="nofollow noreferrer">this post</a>, which includes this</p>
<blockquote>
<p>"(Well written) C++ goes to great
lengths to make stack automatic
objects work "just like" primitives,
as reflected in Stroustrup's advice to
"do as the ints do". This requires a
much greater adherence to the
principles of Object Oriented
development: your class isn't right
until it "works like" an int,
following the "Rule of Three" that
guarantees it can (just like an int)
be created, copied, and correctly
destroyed as a stack automatic."</p>
</blockquote>
<p>I've done a little C, and C++ code, but just in passing, never anything serious, but I'm just curious, what it means exactly?</p>
<p>Can someone give an example?</p>

<p>Are there any useful techniques for reducing the repetition of constants in a CSS file?</p>
<p>(For example, a bunch of different selectors which should all apply the same colour, or the same font size)?</p>

<p>Help! I have an Axis web service that is being consumed by a C# application. Everything works great, except that arrays of long values always come across as [0,0,0,0] - the right length, but the values aren't deserialized. I have tried with other primitives (ints, doubles) and the same thing happens. What do I do? I don't want to change the semantics of my service.</p>

<p>I am trying to set a <code>javascript</code> <code>date</code> so that it can be submitted via <code>JSON</code> to a <code>.NET</code> type, but when attempting to do this, <code>jQuery</code> sets the <code>date</code> to a full <code>string</code>, what format does it have to be in to be converted to a <code>.NET</code> type?</p>
<pre><code>var regDate = student.RegistrationDate.getMonth() + "/" + student.RegistrationDate.getDate() + "/" + student.RegistrationDate.getFullYear();
j("#student_registrationdate").val(regDate); // value to serialize
</code></pre>
<p>I am using <code>MonoRail</code> on the server to perform the binding to a <code>.NET</code> type, that aside I need to know what to set the form hidden field value to, to get properly sent to <code>.NET</code> code.</p>

<p>Is the ZIP compression that is built into Windows XP/Vista/2003/2008 able to be scripted at all? What executable would I have to call from a BAT/CMD file? or is it possible to do it with VBScript?</p>
<p>I realize that this is possible using <a href="http://en.wikipedia.org/wiki/WinZip" rel="noreferrer">WinZip</a>, <a href="http://en.wikipedia.org/wiki/7-Zip" rel="noreferrer">7-Zip</a> and other external applications, but I'm looking for something that requires no external applications to be installed.</p>

<p>I have some C# / asp.net code I inherited which has a textbox which I want to make multiline. I did so by adding textmode="multiline" but when I try to insert a newline, the enter key instead submits the form :P</p>
<p>I googled around and it seems like the default behavior should be for enter (or control-enter) to insert a newline. Like I said I inherited the code so I'm not sure if there's javascript monkeying around or if there's just a simple asp.net thing I have to do.</p>

<p>I'd like to ignore multiple wildcard routes. With asp.net mvc preview 4, they ship with:</p>
<pre><code>RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
</code></pre>
<p>I'd also like to add something like:</p>
<pre><code>RouteTable.Routes.IgnoreRoute("Content/{*pathInfo}");
</code></pre>
<p>but that seems to break some of the helpers that generate urls in my program. Thoughts?</p>

<p>I'm doing some PHP stuff on an Ubuntu server.</p>
<p>The path I'm working in is <strong>/mnt/dev-windows-data/Staging/mbiek/test_list</strong> but the PHP call <code>getcwd()</code> is returning <strong>/mnt/dev-windows/Staging/mbiek/test_list</strong> (notice how it's dev-windows instead of dev-windows-data).</p>
<p>There aren't any symbolic links anywhere. </p>
<p>Are there any other causes for <code>getcwd()</code> returning a different path from a local <code>pwd</code> call?</p>
<p><strong><em>Edit</em></strong> </p>
<p>I figured it out. The <strong>DOCUMENT_ROOT</strong> in PHP is set to <strong>/mnt/dev-windows</strong> which throws everything off.</p>

<p>I'd like to have dashes separate words in my URLs. So instead of:</p>
<pre><code>/MyController/MyAction
</code></pre>
<p>I'd like:</p>
<pre><code>/My-Controller/My-Action
</code></pre>
<p>Is this possible?</p>
