292,167 | <p>I have the following regex expression to match html links:</p>
<pre><code><a\s*href=['|"](http:\/\/(.*?)\S['|"]>
</code></pre>
<p>it kind of works. Except not really. Because it grabs everything after the < a href...
and just keeps going. I want to exclude the quote characters from that last \S match. Is there any way of doing that?</p>
<p><strong>EDIT:</strong> This would make it grab only up to the quotes instead of everything after the < a href btw</p>

292,169 | <p>I'm already familiar with the standard Java package naming convention of using a domain name to create a unique package name (i.e. package <code>com.stackoverflow.widgets</code>). However, I've never seen any recommendations for how to choose package names for personal projects. I assume because this is because this is really a matter of personal taste.</p>
<p>So, how do you choose package names for personal projects that will never make it into production (you might be experimenting with a new framework in your spare time). Assuming you don't have a personal website whose domain you can use to create your package structure, what do (or would) you do? Do you have a logical system in place for generating new package names for hobby projects, or do you just use simple throw-away package names like <code>mypackage</code>?</p>
<p>Since I'm just curious to see what different people's thoughts are on this, I've made this a community wiki.</p>
<p>For me personally, I've never given it much thought, but I wanted to play around with <a href="http://wicket.apache.org/" rel="noreferrer">Wicket</a> tonight and it occurred to me that I don't have a clear idea of how I want to organize my hobby projects. A separate, distinct package naming convention for hobby projects (in my mind, at least) would serve as a good way to keep personal and work-related code clearly separate from each other.</p>
<p>I was thinking of a simple hierarchal naming convention, to keep the source for my personal projects in a single root folder:</p>
<ul>
<li>Use <code>myprojects</code> as the root folder </li>
<li>Append the project name </li>
<li>Add any additional subpackage names</li>
</ul>
<p>So, my Wicket project would be in the package <code>myprojects.learningwicket</code> and unit tests would be in the package <code>myprojects.learningwicket.tests</code> (for example).</p>

292,230 | <p>I have the following table structure</p>
<pre><code>CREATE TABLE `table` (
`id` int(11) NOT NULL auto_increment,
`date_expired` datetime NOT NULL,
`user_id` int(11) NOT NULL,
`foreign_id` int(11) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `date_expired` (`date_expired`,`user_id`,`foreign_id`),
KEY `user_id` (`user_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
</code></pre>
<p>As you'll notice, I have duplicate indexes on user_id: <code>date_expired</code> & <code>user_id</code>. I of course want the unique index because I want to ensure the data is unique.</p>
<p>The reason for the duplicate indexes is because without the <code>user_id</code> index, my main search query takes 4 seconds. With the extra index it takes 1 second. The query is joining the table on <code>user_id</code> and checking <code>date_expired</code>.</p>
<p>The table only has 275 records.</p>
<ul>
<li>How bad is it to have a unique and normal index on the same field?</li>
<li>How bad is it to have larger indexes than data when the table is purely ids?</li>
</ul>

292,257 | <p>My page has two components that depend on JavaScript. On the left-hand side, there is attribute-based navigation (abn). And the right-hand side is the Result of the abn.</p>
<p>There is an event handler for abn and an event handler for the result (both are on clicks)
Whenever the user clicks on the abn, I do an Ajax call which returns a JSON object where the HTML result is a value of one of the key/value pair. The HTML is being inserted into the result component.</p>
<p>The event handler for the result of the page works fine on a page refresh. It stops working when I insert the HTML content into the result slot after the Ajax call. I have verified that the result has all the divs and class that my JavaScript depends on.</p>
<p>I think when I replaced the HTML content, the JavaScript handler just stop working. Can someone explain why this is happening and how I can solve this?</p>

292,279 | <p>I have a function which gets a key from the user and generates a Hashtable (on a pattern specified by the key). After creating a Hashtable, I would like to populate a JTable so that each each column represents a key and every rows represents the values associated with the key. I tried everything but couldn't get this work. I'm not creating the table from within the constructor as I need to get input from the user.</p>

292,363 | <p>I recently wrote a class for an assignment in which I had to store names in an ArrayList (in java). I initialized the ArrayList as an instance variable <code>private ArrayList<String> names</code>. Later when I checked my work against the solution, I noticed that they had initialized their ArrayList in the <code>run()</code> method instead.</p>
<p>I thought about this for a bit and I kind of feel it might be a matter of taste, but in general how does one choose in situations like this? Does one take up less memory or something?</p>
<p>PS I like the instance variables in Ruby that start with an @ symbol: they are lovelier.</p>
<p>(meta-question: What would be a better title for this question?)</p>

292,378 | <p>I have a number of user permissions that are tested throughout my ASP.NET application. These permission values are referenced in an Enum so that I can conveniently test permissions like so:</p>
<ul>
<li>btnCreate.Enabled = PermissionManager.TestPermission(Permission.AllowCreate);</li>
</ul>
<p>However, I also have these permissions stored in the database because I need hold more info about them than just their Id. But this creates a horrible dependency between the enum values and those in the database, an ill considered change to either and I have problems throughout my application. Is there a better way around this issue? Has anyone dealt with this before?</p>

292,395 | <p>I'm writing a simple templating layer in PHP but I've got myself a little stuck. Here's how it works at the moment:</p>
<p>Firstly I use <code>fetch_template</code> to load the template contents from the database - this works (and I collect all the templates at startup if you're interested).</p>
<p>I use PHP variables in my template code and in the logic - e.g.:</p>
<pre><code>// PHP:
$name = 'Ross';
// Tpl:
<p>Hello, my name is $name.</p>
</code></pre>
<p>I then use <code>output_template</code> (below) to parse through the variables in the template and replace them. Previously I was using template tags with a glorified <code>str_replace</code> template class but it was too inefficient.</p>
<pre><code>/**
* Returns a template after evaluating it
* @param string $template Template contents
* @return string Template output
*/
function output_template($template) {
eval('return "' . $template . '";');
}
</code></pre>
<p>My problem, if you haven't already guessed, is that the variables are not declared inside the function - therefore the function can't parse them in <code>$template</code> unless I put them in the global scope - which I'm not sure I want to do. That or have an array of variables as a parameter in the function (which sounds even more tedious but possible).</p>
<p>Does anyone have any solutions other than using the code from the function (it is only a one-liner) in my code, rather than using the function?</p>
<p>Thanks,
Ross</p>
<p><em>P.s. I know about Smarty and the vast range of templating engines out there - I'm not looking to use them so please don't suggest them. Thanks!</em></p>

292,403 | <p>Say that I have two models- Users and Accounts. Each account can have at most n users associated with it, and a user can only be associated with one account. </p>
<p>It would seem natural to say that User </p>
<pre><code>belongs_to :account
</code></pre>
<p>and Account </p>
<pre><code>has_many :users
</code></pre>
<p>However, I'm not clear on the best practice when it comes to limiting the number of associations through that has_many declaration. I know that there is a :limit argument, but that that only limits the number of associations returned, not the number that are able to exist.</p>
<p>I suspect that the answer is to use something like :before_add. However, that approach seems only to apply to associations created via << . So it would get called when you used</p>
<pre><code>@account.users << someuser
</code></pre>
<p>but not if you used </p>
<pre><code>@account.users.create
</code></pre>
<p>I had also considered that it might be more practical to implement the limit using before_save within the User model, but it seems like it would be a bit off to implement Account business rules within the User model.</p>
<p>What is the best practice for limiting the number of associations?</p>
<p>Edit: the n users per account would be some business data that is stored within the individual accounts, rather than being a straight up magic number that would be floating around willy nilly in the code.</p>

292,437 | <p>In .net (C#), If you have two types discovered through reflection is it possible to determine if one can be cast to the other? (implicit and/or explicit).</p>
<p>What I'm trying to do is create a library that allows users to specify that a property on one type is mapped to a property on another type. Everything is fine if the two properties have matching types, but I'd like to be able to allow them to map properties where an implicit/explicit cast is available. So if they have </p>
<pre><code>class from
{
public int IntProp{get;set;}
}
class to
{
public long LongProp{get;set;}
public DateTime DateTimeProp{get;set;}
}
</code></pre>
<p>they would be able to say that from.IntProp will be assigned to to.LongProp (as an implicity cast exists). But if they said that it mapped to DateTimeProp I'd be able to determine that there's no available cast and throw an exception.</p>

292,450 | <p>I need to do some process injection using C++ but I would prefer to use C# for everything other than the low level stuff.

<p>How can I wrap all the lower level stuff (native C++) in C# so I can easily command those functions in a language I am more comfortable with, C#? </p>

292,453 | <p>I'm looking into the feasibility of adding a function to my Rails-based intranet site that allows users to upload files.</p>
<p>Two purposes:
My users are widely distributed geographically and linking to documents on the shared network storage doesn't always work (different addresses, DNS entries and stuff outside my control or interest) so I'm thinking about providing a database-oriented alternative.
We have a number of files from which we parse data at the client end. I'd rather like to be able to push that up to the server.</p>
<p>I've looked at attachment_fu, Paperclip and another one (forgotten the name!) all of which seem very image-oriented, although attachment_fu at least can work without a image processing library present, thank goodness.</p>
<p>The big problem is that my server does not permit my application to write files locally, and these plugins all seem to want to create a Tempfile.</p>
<p>The questions (finally!)</p>
<p>Is there a reasonable way to upload binary data and process it in memory and/or store it as a BLOB without any server-side file saves?</p>
<p>Or should I give up on the file distribution idea and give the users a second-best option of copy-and-paste text boxes where possible?</p>
<p>(Closest I could find on SO was <a href="https://stackoverflow.com/questions/116353/uploading-files-in-ruby-on-rails">this</a> which doesn't really help)</p>

292,464 | <p>Since I've started using NetBeans, I've learned of some <a href="http://www.netbeans.org/kb/60/java/gui-db.html" rel="nofollow noreferrer">powerful ways</a> to abstract away the process of creating Java database applications with automatically generated UI, beans bindings, and a bunch of other stuff I only vaguely understand the workings of at the moment (I hate being a newb). Problem is, <em>how do I do the basic stuff I actually want to do</em>? The tutorials I've read make a big deal about being able to connect to and mess around with a database from within the IDE, or how to create and bind some UI sliders and checkboxes to table columns, etc. But where can I learn about how to make my own code do that stuff? Abstraction is nice and all, but it's quite useless to me at the moment for what I need done.</p>
<p>Can anyone refer me to some good resources or tutorials to learn this? The few I've found aren't proving as useful as I'd hoped to get my project underway...</p>

What about using regular expressions? Can anyone point me in the right direction?</p>

somefile.msi /a<br>

292,551 | <p>Here's the problem: </p>
<p>I have to modify an existing Excel spreadsheet using .NET. The spreadsheet is hugely complex, and I just have to add data in some predefined areas.</p>
<p>I'm investigating my options, and Excel Automation/InterOp is out of the question, as I'm implementing an ASP.NET website, and Excel probably isn't installed on the server. From what I find online, InterOp is also a very expensive solution performancewise.</p>
<p>Creating a CSV file is also ruled out because of the complex nature of the original spreadsheet.</p>
<p>Currently I'm leaning towards an ADO.NET OleDb solution, but I find that mentioned very rarely (Google and Stackoverflow.com) so I'm kinda worried: What's the catch with OldDb for Excel?
The only drawback I can find on MSDN so far, is that I can't create cells with formulas, but that's really not an issue in my case.</p>
<p>I've also considered SSIS, but that's only based on my assumption that you can use existing Excel files when you generate spreadsheets. I don't know if that possible or not.</p>
<p>Then there's OpenXml. It seems overly complicated compared to OldDb, plus it's still undetermined which of the older Excel versions I have to support.</p>
<p>Am I missing something? Are there more alternatives?</p>

292,552 | <p>I'm wondering to using extension method to avoid checking for null in hierarchy.
The example:</p>
<pre><code>// GetItems(), GetFirstOrDefault(), GetProduct(), GetIDProduct() are extension methods like:
public static SomeType GetSomeProperty( this XYZ obj ) {
if ( object.ReferenceEquals( obj, null ) ) { return default( SomeType ); }
return obj.SomeProperty;
}
// the code with extension methods
Guid? idProduct = this.Invoice.GetItems().GetFirstOrDefault().GetProduct().GetIDProduct();
// instead of
Guid? idProduct = null;
Invoice invoice = this.Invoce;
if ( null != invoice ) {
InvoiceItems items = invoice.Items;
if ( null != items && items.Count > 0 ) {
InvoiceItem item = items[0];
if ( null != item ) {
idProduct = item.IDProduct();
}
}
}
</code></pre>
<p>I know, there is available Null Object pattern, but the solution with this type of extension methods looks better.</p>
<p>Do you think, this solution is good or bad (because bad/good design, lucidity, whatever else)?</p>
<p>Please vote "Good" or "Bad" and why do you think so.

292,564 | <p>I have looked at the SQL Server 2008 feature comparison matrix and it lists the express/web and workgroup editions as having the SSIS runtime. Does this mean it is possible to develop SSIS packages using the developer edition, and then deploy and run them on a server running one of the lowly SQL Server editions such as SQL Server 2008 Express edition?</p>

292,587 | <p>I'm writing a J2ME application. One of the pieces is something that polls the contents of a directory periodically, and, if there are any new things, paints them on the screen. I've done this by having the UI form launch a polling thread with a pointer back to itself, and when the polling thread finds something it calls back to the form and calls a syncrhonized method to update it's display. This seems to work fine.</p>
<p>The question I have is this. In C#/.NET I know it is not nice to have non-UI threads updating the UI, and the correct way to handle this is to delegate it up to the UI thread. </p>
<p>E.g. the following:</p>
<pre><code>public void DoSomeUIThing()
{
if (this.uiComponent.InvokeRequired)
{
this.uiComponent.Invoke(someDelegateThatCallsBackToThis);
}
else
{
this.uiComponent.Text = "This is the update I want to happen";
}
}
</code></pre>
<p>Is there a J2ME equivalent for how to manage this process? How about Java? Or does Java/J2ME just play nicer in regard to this? If not, how is this done?</p>
<p>[EDIT] It appears that Swing supports what I'm asking about via the SwingUtilities.invokeLater() and invokeAndWait() methods. Is there an equivalent framework for J2ME?</p>

292,646 | <p>I need to pick up list items from an list, and then perform operations like adding event handlers on them. I can think of two ways of doing this.</p>
<p>HTML:</p>
<pre><code> <ul id="list">
<li id="listItem-0"> first item </li>
<li id="listItem-1"> second item </li>
<li id="listItem-2"> third item </li>
</ul>
</code></pre>
<ol>
<li><p>Using the IDs-</p>
<pre><code>for(i=0;i<3;i++)
{
document.getElementById("listItem-"+i).addEventListener("click",foo,false);
}
</code></pre></li>
<li><p>Using childNodes property-</p>
<pre><code>for(i=0;i<3;i++)
{
document.getElementById("list").childNodes[i]
.addEventListener("click",foo,false);
}
</code></pre></li>
</ol>
<p>The reason i'm using the first approach is that in the function foo, if I want the index at which the item is located in the list, i can do it by splitting the id -</p>
<pre><code> function foo()
{
tempArr = this.id.split('-');
index = tempArr[tempArr.length-1]; // the last element in the array
}
</code></pre>
<p>I can't think of a way of doing it by using the second method, that is, without using the id naming scheme.</p>
<p>The questions:</p>
<ol>
<li>How do I get the index using the second method or any better method</li>
<li>Are there some very bad affects of following the first method ? </li>
</ol>

292,667 | <p>Let's start with the following snippet:</p>
<pre><code>Foreach(Record item in RecordList){
..
item = UpdateRecord(item, 5);
..
}
</code></pre>
<p>The UpdateRecode function changes some field of item and returns the altered object. In this case the compiler throws an exception saying that the item can not be updated in a foreach iteration. </p>
<p>Now the UpdateRecord method is changed so that it returns void and the snippet would look like this:</p>
<pre><code>Foreach(Record item in RecordList){
..
UpdateRecord(item, 5);
..
}
</code></pre>
<p>In this case the item would be updated because Record is a reference type. But it makes the code unreadable.</p>
<p>The project I'm working on has lots of foreach-loops with the almost the same code over and over, so I would like to create methods that update parts of the records. Is there a nice way to do this? One that make the code more readable instead of trashing it further more?</p>

292,676 | <p>Unlike C++, in C# you can't overload the assignment operator. </p>
<p>I'm doing a custom Number class for arithmetic operations with very large numbers and I want it to have the look-and-feel of the built-in numerical types like int, decimal, etc. I've overloaded the arithmetic operators, but the assignment remains...</p>
<p>Here's an example:</p>
<pre><code>Number a = new Number(55);
Number b = a; //I want to copy the value, not the reference
</code></pre>
<p>Is there a workaround for that issue?</p>

292,706 | <p>I have a table like the following:</p>
<pre><code>transaction_id
user_id
other_user_id
trans_type
amount
</code></pre>
<p>This table is used to maintain the account transactions for a finance type app.</p>
<p>Its double entry accounting so a transfer from User A to B would insert two rows into the table looking like.</p>
<pre><code>1, A, B, Sent, -100
1, B, A, Received, 100
</code></pre>
<p>The balance on any account is calculated by summing up the transactions for that account.</p>
<p>For example:</p>
<pre><code>select sum(amount) from transactions where user_id=A
</code></pre>
<p>What is the best way to lock down transferring of funds? My current code looks like:</p>
<pre><code>Start Transaction
Debit the sender's account
check the balance of the sender's account
if new balance is negative then the sender didn't have enough money and rollback
if the balance is positive then credit the receiver and commit
</code></pre>
<p>This seems not to be working exactly as expected. I see a lot of examples online about transactions that say basically: start, debit sender, credit receiver, commit. But what is the best way to check the sender's balance in between?</p>
<p>I have transactions getting through that shouldn't. Say a user has a balance of 3K and two transactions come in at exactly the same time for 3K, both of these are getting through when only one should.</p>
<p>Thank you</p>

<p>Is there anyway that I can do this without flash or silverlight?

292,711 | <p>How are you managing your usage of <a href="http://dojotoolkit.org/projects/dojox" rel="nofollow noreferrer">DojoX</a> code or widgets in a production application?</p>
<p>The <a href="http://dojotoolkit.org/" rel="nofollow noreferrer">Dojo Toolkit</a> is comprised of Core, Dijit, and DojoX. As an incubator for new ideas to extend the toolkit, DojoX code and widgets are functional with varying degrees of instability. </p>
<p>DojoX Code like <em><a href="http://dojotoolkit.org/book/book-dojo/part-3-javascript-programming-dojo-and-dijit/using-dojo-data/available-stores/dojox-d" rel="nofollow noreferrer">QueryReadStore</a></em> (for fetching batches of data from the server) or widgets like <em><a href="http://dojotoolkit.org/book/dojo-book-0-9/docx-documentation-under-development/grid" rel="nofollow noreferrer">Grid</a></em> (for utilizing a user interface grid component) are not included in Core or Dijit. But they are functional enough to utilize in some cases, with the caveat "developer beware", because in future Toolkit versions the API or the component location in the source tree might change. Another catch is that you may have to tweak the DojoX component you are using for it to function properly in your environment, as there's not yet a high degree of robustness in the code. </p>
<p>So, how are you ensuring that as the DojoX components you use evolve, your application stays on a smooth track?</p>

292,740 | <p>I am implementing a very simple file database. I have 2 basic operations: </p>
<pre><code>void Insert(const std::string & i_record)

m_fileStream.open(m_fileName.c_str(), std::ios::out | std::ios::app);

m_fileStream.flush();

*/
std::vector<std::string> SelectAll()
{
std::vector<std::string> results;
m_fileStream.open(m_fileName.c_str(), std::ios::in);
std::string line;
if (m_fileStream.is_open())
{
while (!m_fileStream.eof())
{
getline (m_fileStream, line);
results.push_back(line);
}
}
m_fileStream.close();
return results;
}
</code></pre>
<p>the class has m_fileStream and m_fileName as private members. </p>
<p>OK - here's the problem: </p>
<p>If I do something like: </p>
<pre><code>db->Insert("a");
db->SelectAll();
db->Insert("b");
</code></pre>
<p>The end result is that the file will contain <em>only</em> "a"; WHY? </p>
<p>NOTE: it seems that getline() will set the fail bit. but why?</p>

292,756 | <p>In my master pages I have <code><form ... action="" ...></code>, in pre SP1, if I viewed the source the action attribute would be an empty string. In SP1 the action attribute is overridden "MyPage.aspx?MyParams", unfortunately, this causes my postbacks to fail as I have additional pathinfo in the URL (ie. MyPage.aspx\CustomerData?MyParams). I have checked the action attribute in the OnLoad event and it is still blank at this time, so somewhere SP1 is overriding this :(.</p>
<p>Sorry, I just realized that part of my post was missing since I did not use the markdown correctly.</p>

292,767 | <p>So, I'm reasonably new to both unit testing and mocking in C# and .NET; I'm using xUnit.net and Rhino Mocks respectively. I'm a convert, and I'm focussing on writing behaviour specifications, I guess, instead of being purely TDD. Bah, semantics; I want an automated safety net to work above, essentially.</p>
<p>A thought struck me though. I get programming against interfaces, and the benefits as far as breaking apart dependencies goes there. Sold. However, in my behaviour verification suite (aka unit tests ;-) ), I'm asserting behaviour one interface at a time. As in, one implementation of an interface at a time, with all of its dependencies mocked out and expectations set up.</p>
<p>The approach seems to be that if we verify that a class behaves as it should against its collaborating dependencies, and in turn relies on each of those collaborating dependencies to have signed that same quality contract, we're golden. Seems reasonable enough.</p>
<p>Back to the thought, though. Is there any value in semi-integration tests, where a test-fixture is asserting against a unit of concrete implementations that are wired together, and we're testing its internal behaviour against mocked dependencies? I just re-read that and I think I could probably have worded it better. Obviously, there's going to be a certain amount of "well, if it adds value for you, keep doing it", I suppose - but has anyone else thought about doing that, and reaped benefits from it outweighing the costs?</p>

292,806 | <p>I'm not sure how to search for this answer, so I'll go ahead and ask it.</p>
<p>In my rails project I have a User model and a foo model. A user can have one or more foo models assigned to it. I have accomplished this by adding </p>
<pre><code>has_many :foo, :through => :user_foo
</code></pre>
<p>in my user model. </p>
<p>Now, over in my view, I want to display a list of all foos. Not just the ones that are selected (i will be making these radio buttons, but that's another question). When I try to do this (yes, i'm using haml):</p>
<pre><code> - for foo in @foos
</code></pre>
<p>I get this error:</p>
<pre><code>You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
</code></pre>
<p>My assumption is that this is caused because the @foos collection is empty. What is the proper way to get access to this collection within my user view?</p>
<p>** edit **</p>
<p>I think my initial question was a bit confusing. the first issue i'm trying to figure out is how to access a collection of foos from within my user view. the relationship doesn't matter. I just want a list of all foos in the system. not just the ones assigned to the user.</p>

292,820 | <p>In a code review, I stumbled over this (simplified) code fragment to unregister an event handler:</p>
<pre><code> Fire -= new MyDelegate(OnFire);
</code></pre>
<p>I thought that this does not unregister the event handler because it creates a new delegate which had never been registered before. But searching MSDN I found several code samples which use this idiom.</p>
<p>So I started an experiment:</p>
<pre><code>internal class Program
{
public delegate void MyDelegate(string msg);
public static event MyDelegate Fire;
private static void Main(string[] args)
{
Fire += new MyDelegate(OnFire);
Fire += new MyDelegate(OnFire);
Fire("Hello 1");
Fire -= new MyDelegate(OnFire);
Fire("Hello 2");
Fire -= new MyDelegate(OnFire);
Fire("Hello 3");
}
private static void OnFire(string msg)
{
Console.WriteLine("OnFire: {0}", msg);
}
}
</code></pre>
<p>To my surprise, the following happened:</p>
<ol>
<li><code>Fire("Hello 1");</code> produced two messages, as expected.</li>
<li><code>Fire("Hello 2");</code> produced one message!<br>
This convinced me that unregistering <code>new</code> delegates works!</li>
<li><code>Fire("Hello 3");</code> threw a <code>NullReferenceException</code>.<br>
Debugging the code showed that <code>Fire</code> is <code>null</code> after unregistering the event.</li>
</ol>
<p>I know that for event handlers and delegate, the compiler generates a lot of code behind the scene. But I still don't understand why my reasoning is wrong.</p>
<p>What am I missing?</p>
<p>Additional question: from the fact that <code>Fire</code> is <code>null</code> when there are no events registered, I conclude that everywhere an event is fired, a check against <code>null</code> is required.</p>

292,826 | <p>I have a canvas in Flex that shall be able only to be scrolled in vertical direction, so I set the attributes of the canvas as follows:</p>
<pre><code>verticalScrollPolicy="auto" horizontalScrollPolicy="off"
</code></pre>
<p>The problem here is that the vertical scrollbar covers the content when it appears - altough there is enough horizontal room left. I would have expected that the content size would have been automatically adjusted.</p>
<p>When setting the vertical scroll policy to "on", no content is covered also.</p>
<p>In case I set both scroll policies to 'auto' I also get a horizontal scroll bar just for scrolling to the area that is covered by the vertical scroll bar.</p>
<p>Is there a workaround how I can relayout the content of the canvas when the vertical scroll bar is shown so that it does not cover any content?</p>

292,844 | <p>I try to keep it brief and concise. I have to write a program that takes queries in SQL form and searches an XML. Right now I am trying to disassemble a string into logical pieces so I can work with them. I have a string as input and want to get a MatchCollection as output.</p>
<p>Please not that the test string below is of a special format that I impose on the user to keep things simple. Only one statement per line is permitted and nested queries are excluded-</p>
<p>string testString = "select apples \n from dblp \r where we ate \n group by all of them \r HAVING NO SHAME \n";</p>
<p>I use Regex with the following pattern:</p>
<pre><code>Regex reg = new Regex(@"(?<select> \A\bselect\b .)" +
@"(?<from> ^\bfrom\b .)" +
@"(?<where> ^\bwhere\b .)" +
@"(?<groupBy> ^\bgroup by\b .)" +
@"(?<having> ^\bhaving\b .)"
, RegexOptions.IgnoreCase | RegexOptions.Multiline
);
</code></pre>
<p>As far as I know this should give me matches for every group with the test string. I would be looking for an exact match of "select" at the start of each line followed by any characters except newlines.</p>
<p>Now I create the collection:</p>
<pre><code>MatchCollection matches = reg.Matches(testString);
</code></pre>
<p>To makes sure it worked I used a foreach and printed the matches like:</p>
<pre><code>foreach(Match match in matches)
{
Console.WriteLine("Select: {0}", match.Groups["select"]);
//and so on
}
</code></pre>
<p>The problem is that the collection is always empty. There must be a flaw in the Regex somewhere but I am too inexperienced to find it. Could you please assist me? Thank you very much!</p>
<hr>
<p>I tried using .* instead of just . until I was told that . would even mathc multiple character. I have no doubt that this could be a problem but even when replacing it I get no result.</p>
<p>I fail to see why it is so difficult to match a line starting with a defined word and having any characters appended to it until the regex finds a newline. Seems to me that this should be a relatively easy task.</p>

292,861 | <p>I have a form that has default values describing what should go into the field (replacing a label). When the user focuses a field this function is called:</p>
<pre><code>function clear_input(element)
{
element.value = "";
element.onfocus = null;
}
</code></pre>
<p>The onfocus is set to null so that if the user puts something in the field and decides to change it, their input is not erased (so it is only erased once). Now, if the user moves on to the next field without entering any data, then the default value is restored with this function (called onblur):</p>
<pre><code>function restore_default(element)
{
if(element.value == '')
{
element.value = element.name.substring(0, 1).toUpperCase()
+ element.name.substring(1, element.name.length);
}
}
</code></pre>
<p>It just so happened that the default values were the names of the elements so instead of adding an ID, I just manipulated the name property. The problem is that if they do skip over the element then the onfocus event is nullified with clear_input but then never restored.</p>
<p>I added</p>
<pre><code>element.onfocus = "javascript:clear_input(this);";
</code></pre>
<p>In restore_default function but that doesn't work. How do I do this?</p>

292,887 | <p>What is the best way to store DateTime in SQL for different timezones and different locales<br>
There a few questions/answers about timezones, but none is addressing the locale problems.
DateTime.ToUniversalTime is locale specific, and I need it locale independent.</p>
<p>For example:</p>
<pre><code> DateTime.Now.ToUniversalTime.ToString()
In US locale returns something like: 11/23/2008 8:20:00
In France locale returns 23/11/2008 8:20:00
Notice that day/month are inverted
</code></pre>
<p>If you save the DateTime while in France Locale on a US SQL DB - you get an error, because it is a wrong date format. </p>
<p>Best would be a C# code snippet for</p>
<ol>
<li>Get a DateTime in a specific locale and store it in SQL datetime field</li>
<li>Retrieved a SQL datetime field and convert it to a locale DateTime</li>
</ol>
<p>Thanks</p>

292,893 | <p>This code is causing a memory leak for me, and I'm not sure why.</p>
<p>[EDIT] Included code from <a href="http://paste.pocoo.org/show/91254/" rel="nofollow noreferrer">here</a> into question:</p>
<pre><code>#include "src/base.cpp"
typedef std::map<std::string, AlObj*, std::less<std::string>,
gc_allocator<std::pair<const std::string, AlObj*> > > KWARG_TYPE;
AlInt::AlInt(int val) {
this->value = val;
this->setup();
}
// attrs is of type KWARG_TYPE
void AlInt::setup() {
this->attrs["__add__"] = new AddInts();
this->attrs["__sub__"] = new SubtractInts();
this->attrs["__mul__"] = new MultiplyInts();
this->attrs["__div__"] = new DivideInts();
this->attrs["__pow__"] = new PowerInts();
this->attrs["__str__"] = new PrintInt();
}
int main() {
while (true) {
AlObj* a = new AlInt(3);
}
}
</code></pre>
<p>AlInt inherits from AlObj, which in turn inherits from gc. When I comment out the contents of setup() then I don't have a memory leak, this leads me to believe the issue is with the map not cleaning up, however I'm using the gc allocator, so I'm not sure where to look next. Thoughts?</p>

292,941 | <p>I've rewritten my family web site using JavaScript (JQuery) making Ajax calls to PHP on the back end. It's your standard "bunch of image thumbnails and one main image, and when you click on a thumbnail image the main image changes" kind of thing. Everything is working as expected when using Firefox, but on IE, when I click on a thumbnail, the main image changes to the one I clicked and then immediately changes back to the first one. I have tried MS Script Debugger to no avail; I set a breakpoint in the JavaScript code that starts the Ajax call, and when I click the thumbnail the breakpoint fires. Then I hit F5 and it continues but does not fire again. If I use Wireshark to watch the actual TCP packets over the network, I can see that we are definitely sending more than one request to the server. I cannot figure out where the second query (the one to revert back to the original image) comes from.</p>
<p>Any suggestions? One example of what I'm talking about is <a href="http://perrow.ca/gallery.php?tag=nicholas-1" rel="nofollow noreferrer">here</a>.</p>

292,991 | <p>I need to allow the vertical scrollbar in a multiselect listbox (VB6) however, when the control is disabled, I can't scroll.</p>
<p>I would think there is an API to allow this, but my favorite <a href="http://vbnet.mvps.org" rel="nofollow noreferrer">VB6 site (MVPS VB.NET)</a> does not have a way.</p>
<p>I toyed with pretending it was disabled, and ignore the clicks... but to do that with VB6 code is really ugly... so if this is a solution, I need an API to ignore the clicks.</p>
<p>Thanks for your help.</p>

292,993 | <p>What's the secret to getting ClaimsResponse working with <a href="http://code.google.com/p/dotnetopenid/" rel="noreferrer">DotNetOpenId</a>?</p>
<p>For example, in this bit of code (from <a href="http://www.hanselman.com/blog/CategoryView.aspx?category=DasBlog" rel="noreferrer">Scott Hanselman's blog</a>) the ClaimsResponse object should have lots of nice little things like 'nickname' and 'email address', but the ClaimsResponse object itself is 'null':</p>
<pre><code> OpenIdRelyingParty openid = new OpenIdRelyingParty();
if (openid.Response != null)
{
// Stage 3: OpenID Provider sending assertion response
switch (openid.Response.Status)
{
case AuthenticationStatus.Authenticated:
ClaimsResponse fetch = openid.Response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse;
string nick = fetch.Nickname;
string homepage = openid.Response.ClaimedIdentifier;
string email = fetch.Email;
string comment = Session["pendingComment"] as string;
string entryId = Session["pendingEntryId"] as string;
if (String.IsNullOrEmpty(comment) == false && String.IsNullOrEmpty(entryId) == false)
{
AddNewComment(nick, email, homepage, comment, entryId, true);
}
break;
}
}
</code></pre>
<p>At first, I thought it was because I wasn't redirecting to the provider with a 'ClaimsRequest' ... but using this code to redirect to the OpenId provider still doesn't help:</p>
<pre><code>OpenIdRelyingParty openid = new OpenIdRelyingParty();
IAuthenticationRequest req = openid.CreateRequest(openid_identifier.Text);
ClaimsRequest fetch = new ClaimsRequest();
fetch.Email = DemandLevel.Require;
fetch.Nickname = DemandLevel.Require;
req.AddExtension(fetch);
req.RedirectToProvider();
</code></pre>
<p>What am I doing wrong? Or have other devs experienced the same pain?</p>

293,006 | <p>We've trying to separate a big code base into logical modules. I would like some recommendations for tools as well as whatever experiences you might have had with this sort of thing. </p>
<p>The application consists of a server WAR and several rich-clients distributed in JARs. The trouble is that it's all in one big, hairy code base, one source tree of > 2k files war. Each JAR has a dedicated class with a <code>main</code> method, but the tangle of dependencies ensnares quickly. It's not all that bad, good practices were followed consistently and there are components with specific tasks. It just needs some improvement to help our team scale as it grows.</p>
<p>The modules will each be in a maven project, built by a parent POM. The process has already started on moving each JAR/WAR into it's own project, but it's obvious that this will only scratch the surface: a few classes in each app JAR and a mammoth "legacy" project with everything else. Also, there are already some unit and integration tests.</p>
<p>Anyway, I'm interesting in tools, techniques, and general advice to breaking up an overly large and entangled code base into something more manageable. Free/open source is preferred.</p>

293,007 | <p>I want do something like this:</p>
<pre><code>Button btn1 = new Button();
btn1.Click += new EventHandler(btn1_Click);
Button btn2 = new Button();
// Take whatever event got assigned to btn1 and assign it to btn2.
btn2.Click += btn1.Click; // The compiler says no...
</code></pre>
<p>Where btn1_Click is already defined in the class:</p>
<pre><code>void btn1_Click(object sender, EventArgs e)
{
//
}
</code></pre>
<p>This won't compile, of course ("The event 'System.Windows.Forms.Control.Click' can only appear on the left hand side of += or -="). Is there a way to take the event handler from one control and assign it to another at runtime? If that's not possible, is duplicating the event handler and assigning it to another control at runtime doable?</p>
<p>A couple of points: I have googled the heck out of this one for awhile and found no way of doing it yet. Most of the attempted approaches involve reflection, so if you read my question and think the answer is incredibly obvious, please try to compile the code in Visual Studio first. Or if the answer really is incredibly obvious, please feel free to slap me with it. Thanks, I'm really looking forward to seeing if this is possible.</p>
<p>I know I could just do this:</p>
<pre><code>btn2.Click += new EventHandler(btn1_Click);
</code></pre>
<p>That's not what I'm looking for here.</p>
<p>This is also not what I'm looking for:</p>
<pre><code>EventHandler handy = new EventHandler(btn1_Click);
Button btn1 = new Button();
btn1.Click += handy;
Button btn2 = new Button();
btn2.Click += handy;

293,021 | <p>I have a working TYPO3 extension. It is attached <a href="http://wiki.orbeon.com/forms/doc/developer-guide/form-runner-typo3-extension" rel="nofollow noreferrer">this wiki page</a>. How can I change the code of this extension so it is of the USER_INT type? I.e. I don't want TYPO3 to cache the output of this plugin, and want TYPO3 to invoke the extension ever time a page that uses the extension, i.e. disable the caching for this extension.</p>

<p>They show up in AX - but in the SQL-database, they are not mentioned at all... I have a hunch that all custom fields are stored somewhere else in the database, so that the original state of the tables does not get alterd - but where? </p>

293,070 | <p>I'm trying to build a Java regular expression to match "<code>.jar!</code>"</p>
<p>The catch is that I don't want the matcher to consume the exclamation mark. I tried using <code>Pattern.compile("\\.jar(?=!)")</code> but that failed. As did escaping the exclamation mark.</p>
<p>Can anyone get this to work or is this a JDK bug?</p>
<p><strong>UPDATE</strong>: I feel like an idiot, <code>Pattern.compile("\\.jar(?=!)")</code> does work. I was using Matcher.matches() instead of Matcher.find().</p>

293,081 | <p>So standard Agile philosophy would recommend making your domain classes simple POCOs which are Persisted using a separate proxy layer via data access objects (like NHibernate does it). It also recommends getting as high unit test coverage as possible. </p>
<p>Does it make any sense to write tests for these simple POCO objects? Say I have a class which looks like this:</p>
<pre><code>public class Container {
public int ContainerId { get; set;}
public string Name { get; set;}
public IList<Item> Contents { get; set;}
}
</code></pre>
<p>What useful unit tests can I write for this?</p>

293,090 | <p>I think I'm pretty good at using semantic markup on my pages but I still have a handful of classes like this:</p>
<pre><code>/**** Aligns ****/
.right_align { text-align: right; }
.left_align { text-align: left; }
.center_align { text-align: center; }
</code></pre>
<p>Which, technically, is a no-no. But when you just want to position some text in a table, how crazy am I supposed to get with the semantic markup?</p>

293,100 | <p>I have a do-while loop that's supposed to do three things, go through a text file line by line, the text file contains pathnames and filenames (C:\Folder\file1.txt).</p>
<p>If the line contains a certain string, it then copies a file to that location, renames it to what it is named in the text file, and then replaces a string within the copied file.<br />
If not, it goes on to the next line.</p>
<p>I thought this would be fairly straight forward but it doesn't seem to be working. I'm currently unable to even compile as I'm getting errors saying the loop's syntax is wrong.</p>
<p>Any help would be appreciated, here's the entire function's code:</p>
<pre class="lang-vb prettyprint-override"><code>Private Sub Command2_Click()
Dim LineData As String
Dim FileHandle As Integer
FileHandle = FreeFile
Open "C:\textfile.txt" For Input As #FileHandle
Do While Not EOF(FileHandle)
Line Input #FileHandle, LineData
If InStr(LineData, ".log") Then
FileCopy "C:\thefile.log",LineData
Open LineData For Input As #3
#3 = Replace$(#3, "abc", "xyz")
Else
End If
Loop
Close #FileHandle
Close #3
MsgBox "Copy, Replace, Complete!"
End Sub
</code></pre>

293,117 | <p>By convention our DB only alows the use of stored procedures for INSERT, UPDATE and DELETE. For some tables / types there is no DELETE stored procedure, because it is not allowed to delete rows. (You can only update the status of such a type to "deleted"). e.g. a customer may be marked as deleted but is never really removed from the DB.</p>
<p><strong>How do I prevent the use of Delete() for certain types in the Data Access Layer = in the DMBL?</strong></p>
<p>The "Default Methods" for Insert and Update are mapped to the corresponding stored procedure. But for Delete it says <strong>"use runtime"</strong>. I would like to set it to "not allowed".</p>
<p>Is there a way to achieve this on the DB model layer?</p>
<p>Many thanks</p>

293,158 | <p>I'm attempting to create a Wizard type control in VB6 and have run into a stumbling block.</p>
<p>I'd like to allow users of the control to be able to add and manage CWizardPage(s) to the design time control using a property page.</p>
<p>The first approach I used was to add the Wizard pages to the OCX directly using a Collection, however I ran into two problems in that the Collection class is not persistable (and I couldn't find an easy way to make it so) and that VB6 seems very limited in it's ability to instantiate controls at run time - so it would seem to be a struggle to actually re-instantiate them.</p>
<p>My next thought was to just allow the users to draw the wizard pages at design time. This sort of works, however it's far too easy to draw one of the wizard pages inside another wizard page instead of inside the CWizardContainer.</p>
<p>So can anyone please tell me how to add controls to a form at design time without using drag 'n' drop?</p>

293,160 | <p>I'm writing an application that includes a plugin system in a different assembly.</p>
<p>The problem is that the plugin system needs to get application settings from the main app (like the directory to look for plugins).</p>
<p>How is this done, or am I going about this the wrong way?</p>
<p>Edit: I was encouraged to add some details about how the plugin system works. I haven't completely worked that out and I've only just begun implementing it, but I basically went by <a href="http://divil.co.uk/net/articles/plugins/plugins.asp" rel="nofollow noreferrer">this article</a>.</p>

293,215 | <p>In the early days of .NET, I <i>believe</i> there was an attribute you could decorate a class with to specify a default property.</p>
<p>According to some articles I've found, this appears to have been yanked from the framework at some point, because it was a little confusing, and I can see how that is the case. </p>
<p>Still, is there another way to get the functionality it provided?</p>
<p>It looked something like this:</p>
<pre><code><DefaultProperty("Value")> _
Public Class GenericStat
...
Public Property Value() As Integer
...
End Property
...
End Class
</code></pre>
<p>This allowed you to do <code>Response.Write(MyObject)</code> instead of <code>Response.Write(MyObject.Value)</code>... This is not a terribly clunky example, but in some complex object-oriented contexts it gets a little hideous. Please let me know if there is a better way. </p>
<p><b>Note:</b> I am not looking for the Default keyword, which can only be used on properties that take a parameter.</p>

293,216 | <p>I ran into a scenario where LINQ to SQL acts very strangely. I would like to know if I'm doing something wrong. But I think there is a real possibility that it's a bug.</p>
<p>The code pasted below isn't my real code. It is a simplified version I created for this post, using the Northwind database.</p>
<p>A little background: I have a method that takes an <code>IQueryable</code> of <code>Product</code> and a "filter object" (which I will describe in a minute). It should run some "Where" extension methods on the <code>IQueryable</code>, based on the "filter object", and then return the <code>IQueryable</code>.</p>
<p>The so-called "filter object" is a <code>System.Collections.Generic.List</code> of an anonymous type of this structure: <code>{ column = fieldEnum, id = int }</code></p>
<p>The fieldEnum is an enum of the different columns of the <code>Products</code> table that I would possibly like to use for the filtering.</p>
<p>Instead of explaining further how my code works, it's easier if you just take a look at it. It's simple to follow.</p>
<pre><code>enum filterType { supplier = 1, category }
public IQueryable<Product> getIQueryableProducts()
{
NorthwindDataClassesDataContext db = new NorthwindDataClassesDataContext();
IQueryable<Product> query = db.Products.AsQueryable();
//this section is just for the example. It creates a Generic List of an Anonymous Type
//with two objects. In real life I get the same kind of collection, but it isn't hard coded like here
var filter1 = new { column = filterType.supplier, id = 7 };
var filter2 = new { column = filterType.category, id = 3 };
var filterList = (new[] { filter1 }).ToList();
filterList.Add(filter2);
foreach(var oFilter in filterList)
{
switch (oFilter.column)
{
case filterType.supplier:
query = query.Where(p => p.SupplierID == oFilter.id);
break;
case filterType.category:
query = query.Where(p => p.CategoryID == oFilter.id);
break;
default:
break;
}
}
return query;
}
</code></pre>
<p>So here is an example. Let's say the List contains two items of this anonymous type, <code>{ column = fieldEnum.Supplier, id = 7 }</code> and <code>{ column = fieldEnum.Category, id = 3}</code>.</p>
<p>After running the code above, the underlying SQL query of the <code>IQueryable</code> object should contain:</p>
<pre><code>WHERE SupplierID = 7 AND CategoryID = 3
</code></pre>
<p>But in reality, after the code runs the SQL that gets executed is</p>
<pre><code>WHERE SupplierID = 3 AND CategoryID = 3
</code></pre>
<p>I tried defining <code>query</code> as a property and setting a breakpoint on the setter, thinking I could catch what's changing it when it shouldn't be. But everything was supposedly fine. So instead I just checked the underlying SQL after every command. I realized that the first <code>Where</code> runs fine, and <code>query</code> stays fine (meaning <code>SupplierID = 7</code>) until right after the <code>foreach</code> loop runs the second time. Right after <code>oFilter</code> becomes the second anonymous type item, and not the first, the 'query' SQL changes to <code>Supplier = 3</code>. So what must be happening here under-the-hood is that instead of just remembering that <code>Supplier</code> should equal 7, LINQ to SQL remembers that Supplier should equal <code>oFilter.id</code>. But <code>oFilter</code> is a name of a single item of a <code>foreach</code> loop, and it means something different after it iterates.</p>

293,236 | <p>I'm slowly moving from PHP5 to Python on some personal projects, and I'm currently loving the experience. Before choosing to go down the Python route I looked at Ruby. What I did notice from the ruby community was that monkey-patching was both common and highly-regarded. I also came across a <strong>lot</strong> of horror stories regarding the trials of debugging ruby s/w because someone included a relatively harmless library to do a little job but which patched some heavily used core object without telling anyone. </p>
<p>I chose Python for (among other reasons) its cleaner syntax and the fact that it could do everything Ruby can. Python is making OO click much better than PHP ever has, and I'm reading more and more on OO principles to enhance this better understanding.</p>
<p>This evening I've been reading about <a href="http://butunclebob.com/ArticleS.UncleBob.PrinciplesOfOod" rel="noreferrer">Robert Martin's SOLID</a> principles:</p>
<ul>
<li><strong>S</strong>ingle responsibility principle,</li>
<li><strong>O</strong>pen/closed principle,</li>
<li><strong>L</strong>iskov substitution principle,</li>
<li><strong>I</strong>nterface segregation principle, and</li>
<li><strong>D</strong>ependency inversion principle</li>
</ul>
<p>I'm currently up to <strong>O</strong>: <em>SOFTWARE ENTITIES (CLASSES, MODULES, FUNCTIONS, ETC.) SHOULD BE OPEN FOR EXTENSION, BUT CLOSED FOR MODIFICATION</em>. </p>
<p>My head's in a spin over the conflict between ensuring consistency in OO design and the whole monkey-patching thing. I understand that its possible to do monkey-patching in Python. I also understand that being "pythonic" is to follow common, well-tested, oop best-practices & principles.</p>
<p><strong>What I'd like to know is the community's opinion on the two opposing subjects;</strong> how they interoperate, when its best to use one over the other, whether the monkey-patching should be done at all... hopefully you can provide a resolution to the matter for me.</p>

<p>The question asks:</p>
<blockquote>
<p>Write a Haskell programs that takes
the English sentence 'english', looks
up each word in the English-French
dictionary using binary search,
performs word-for-word substitution,
assembles the French translation, and
prints it out.</p>
<p>The function 'quicksort' rejects
duplicate entries (with 'error'/abort)
so that there is precisely one French
definition for any English word. Test
'quicksort' with both the original
'raw_data' and after having added
'("saves", "sauve")' to 'raw_data'.</p>
<p>Here is a von Neumann late-stopping
version of binary search. Make a
literal transliteration into Haskell.
Immediately upon entry, the Haskell
version must verify the recursive
"loop invariant", terminating with
'error'/abort if it fails to hold. It
also terminates in the same fashion if
the English word is not found.</p>
<pre><code>function binsearch (x : integer) : integer
local j, k, h : integer
j,k := 1,n
do j+1 <> k --->
h := (j+k) div 2
{a[j] <= x < a[k]} // loop invariant
if x < a[h] ---> k := h
| x >= a[h] ---> j := h
fi
od
{a[j] <= x < a[j+1]} // termination assertion
found := x = a[j]
if found ---> return j
| not found ---> return 0
fi
</code></pre>
<p>In the Haskell version</p>
<pre><code>binsearch :: String -> Integer -> Integer -> Entry
</code></pre>
<p>as the constant dictionary 'a' of type
'[Entry]' is globally visible. Hint:
Make your string (English word) into
an 'Entry' immediately upon entering
'binsearch'.</p>
<p>The programming value of the
high-level data type 'Entry' is that,
if you can design these two functions
over the integers, it is trivial to
lift them to to operate over Entry's.</p>
</blockquote>
<p>Anybody know how I'm supposed to go about my binarysearch function?</p>

293,247 | <p>I've read a lot about the pros and cons of sizing with either relative or absolute font sizes. Fixed sizes don't zoom in IE6 but that's not much of an issue these days. Accessibility is important, but I assume that all good accessibility software is built to deal with these issues?</p>
<p>I guess it mainly comes down to whether you want to be able to change all font sizes with one rule (i.e. the default font size you set) or whether you want to be able to change a font size somewhere without affecting nested elements (this is the thing that frustrates me most!).</p>
<p>Anyone have any tips?</p>

293,254 | <p>I'm using C# and .NET 3.5. I need to generate and store some T-SQL insert statements which will be executed later on a remote server.</p>
<p>For example, I have an array of Employees:</p>
<pre><code>new Employee[]
{
new Employee { ID = 5, Name = "Frank Grimes" },
new Employee { ID = 6, Name = "Tim O'Reilly" }
}
</code></pre>
<p>and I need to end up with an array of strings, like this:</p>
<pre><code>"INSERT INTO Employees (id, name) VALUES (5, 'Frank Grimes')",
"INSERT INTO Employees (id, name) VALUES (6, 'Tim O''Reilly')"
</code></pre>
<p>I'm looking at some code that creates the insert statements with String.Format, but that doesn't feel right. I considered using SqlCommand (hoping to do <a href="https://stackoverflow.com/questions/265192/how-to-get-the-generated-sql-statment-from-a-sqlcommand-object">something like this</a>), but it doesn't offer a way to combine the command text with parameters.</p>
<p>Is it enough just to replace single quotes and build a string?</p>
<pre><code>string.Format("INSERT INTO Employees (id, name) VALUES ({0}, '{1}')",
employee.ID,
replaceQuotes(employee.Name)
);
</code></pre>
<p>What should I be concerned about when doing this? The source data is fairly safe, but I don't want to make too many assumptions.</p>
<p>EDIT: Just want to point out that in this case, I don't have a SqlConnection or any way to directly connect to SQL Server. This particular app needs to generate sql statements and queue them up to be executed somewhere else - otherwise I'd be using SqlCommand.Parameters.AddWithValue()</p>

293,275 | <p>I am trying to <strong>synchronize</strong> the horizontal <strong>scroll position</strong> of 2 <strong>WPF DataGrid</strong> controls.</p>
<p>I am subscribing to the <strong>ScrollChanged</strong> event of the first DataGrid:</p>
<pre><code><toolkit:DataGrid x:Name="SourceGrid" ScrollViewer.ScrollChanged="SourceGrid_ScrollChanged">
</code></pre>
<p>I have a second DataGrid:</p>
<pre><code><toolkit:DataGrid x:Name="TargetGrid">
</code></pre>
<p>In the event handler I was attempting to use the <strong><code>IScrollInfo.SetHorizontalOffset</code></strong>, but alas, DataGrid doesn't expose <code>IScrollInfo</code>:</p>
<pre><code>private void SourceGrid_ScrollChanged(object sender, ScrollChangedEventArgs e)
{
((IScrollInfo)TargetGrid).SetHorizontalOffset(e.HorizontalOffset);
// cast to IScrollInfo fails
}
</code></pre>
<p>Is there another way to accomplish this? Or is there another element on TargetGrid that exposes the necessary <code>IScrollInfo</code> to achieve the synchronization of the scroll positions?</p>
<p>BTW, I am <strong>using frozen columns</strong>, so I cannot wrap both DataGrid controls with ScrollViewers.</p>

293,276 | <p>I have a custom security principal object which I set in the global.asax for the current thread and all is well, no problems normally.</p>
<p>However, I'm just adding a dynamic image feature by having a page serve up the image and whenever that dynamic image page is loaded the System.Web.HttpContext.Current.Session is null in global.asax which prevents me from setting the security principal as normal and cascading problems from that point onwards.</p>
<p>Normally the Session is null in global.asax only once during a session at the start when the user logs in, afterwards it's always available with this single exception.</p>
<p>The dynamic image page is loaded when the browser comes across an image tage in the original page i.e. </p>
<p>I'm guessing that this is some aspect of the fact that the browser is requesting that page without sending some credentials with it?</p>

293,302 | <p>I have a Rails app with some basic models. The website displays data retrieved from other sources. So I need to write a Ruby script that creates new instances in my database. I know I can do that with the test hooks, but I'm not sure that makes sense here.</p>
<p>I'm not sure what this task should look like, how I can invoke it, or where it should go in my source tree (lib\tasks?).</p>
<p>For example, here's my first try:</p>
<pre><code>require 'active_record'
require '../app/models/mymodel.rb'
test = MyModel.new
test.name = 'test'
test.save
</code></pre>
<p>This fails because it can't get a connection to the database. This makes sense in a vague way to my newbie brain, since presumably Rails is doing all the magic work behind the scenes to set all that stuff up. So how do I set up my little script?</p>
