362,489 | <p>Using <a href="https://numpy.org/" rel="nofollow noreferrer">NumPy</a>, a matrix A has n rows and m columns, and I want add a guard ring to matrix A. That guard ring is all zero.</p>
<p>What should I do? Use Reshape? But the element is not enough to make a n+1 m+1 matrix.</p>
<p>Or etc.?</p>
<p>Thanks in advance</p>
<h6>I mean an extra ring of cells that always contain 0 surround matrix A.Basically there is a Matrix B has n+2rows m+2columns where the first row and columns and the last row and columns are all zero,and the rest of it are same as matrix A.</h6>

362,503 | <p>I have been trying to remove the text before and after a particular character in each line of a text. It would be very hard to do manually since it contain 5000 lines and I need to remove text before that keyword in each line. Any software that could do it, would be great or any Perl scripts that could run on Windows. I run Perl scripts in ActivePerl, so scripts that could do this and run on ActivePerl would be helpful.</p>
<p>Thanks</p>

362,522 | <p>I recently tried switching from using <code>python-mode.el</code> to <code>python.el</code> for editing python files in emacs, found the experience a little alien and unproductive, and scurried back. I've been using <code>python-mode.el</code> for something like ten years, so perhaps I'm a little set in my ways. I'd be interested in hearing from anyone who's carefully evaluated the two modes, in particular of the pros and cons they perceive of each and how their work generally interacts with the features specific to <code>python.el</code>.</p>
<p>The two major issues for me with <code>python.el</code> were </p>
<ol>
<li><p>Each buffer visiting a python file gets its own inferior interactive python shell. I am used to doing development in one interactive shell and sharing data between python files. (Might seem like bad practice from a software-engineering perspective, but I'm usually working with huge datasets which take a while to load into memory.)</p></li>
<li><p>The skeleton-mode support in python.el, which seemed absolutely gratuitous (python's syntax makes such automation unnecessary) and badly designed (for instance, it has no knowledge of "<code>for</code>" loop generator expressions or "<code><expr 1> if <cond> else <expr 2></code>" expressions, so you have to go back and remove the colons it helpfully inserts after insisting that you enter the expression clauses in the minibuffer.) I couldn't figure out how to turn it off. There was a <code>python.el</code> variable which claimed to control this, but it didn't seem to work. It could be that the version of <code>python.el</code> I was using was broken (it came from the debian emacs-snapshot package) so if anyone knows of an up-to-date version of it, I'd like to hear about it. (I had the same problem with the version in CVS emacs as of approximately two weeks ago.)</p></li>

362,541 | <p>I'm new to TDD. So any help would be appreciated. I'm using NUnit and Rhino mocks.
How can I set the ID value to 1 in my mock object?</p>

but the reflection doesn't seem to work against interfaces.</p>
<pre><code> public interface IBatchInfo
{
int ID { get;}
Branches Branch { get; set; }
string Description { get; set; }
}
[SetUp]
public void PerFixtureSetup()
{
_mocks = new MockRepository();
_testRepository = _mocks.StrictMock<IOLERepository>();
}
[Test]
public void ItemsAreReturned()
{
IBatchInfo aBatchItem= _mocks.Stub<IBatchInfo>();
aBatchItem.ID = 1; //fails because ID is a readonly property
aBatchItem.Branch = Branches.Edinburgh;
List<IBatchInfo> list = new List<IBatchInfo>();
list.Add( aBatchItem);
Expect.Call(_testRepository.BatchListActive()).Return(list);
_mocks.ReplayAll();
BatchList bf = new BatchList(_testRepository, "usercreated", (IDBUpdateNotifier)DBUpdateNotifier.Instance);
List<Batch> listofBatch = bf.Items;
Assert.AreEqual(1, listofBatch.Count);
Assert.AreEqual(1, listofBatch[0].ID);
Assert.AreEqual( Branches.Edinburgh,listofBatch[0].Branch);

362,544 | <p>I was trying to find online some exercises to practice scaling techniques (memchached, SQL Optimization, sharding dbs), but I could only find descriptions of these techniques, not any project on which to try them.</p>
<p>This link with <a href="http://www.slideshare.net/Georgio_1999/how-to-scale-your-web-app" rel="nofollow noreferrer">slides on scaling techniques</a>, is an interesting one, as it sums up some tools to achieve scalability quite well.</p>
<p>Is there a projecteuler kind of site for these kind of activities? Or at least some excercises (such as a downloadable ASP.NET/PHP site with obvious slowdowns, concurrency issues, subtle bugs) for people to try and learn how to fight this issue?</p>

362,548 | <p>I am trying to find the best practice for generating and outputting html which would require a database query first to obtain the info. Currently in the aspx page I have a div with runat server:</p>
<pre><code><div runat="server" id="leaflet"></div>
</code></pre>
<p>Now just as a start to do a bit of testing I have a method that runs on page_load that basically does:</p>
<pre><code>private void BuildLeaflet(string qnid)
{
//gets leaflet details
QueryLeafletDetails();
//return concatenated content string
leaflet.InnerHtml "<h1>" + dr["LSC Descriptor"] + "</h1>";
}
</code></pre>
<p>In the real solution the return is a concatenation of about 10 fields some very long as they are content. </p>
<p>I don't by any means think this is the best solution, but what is? A StringBuilder? Can I Write Each Part in turn to the site avoiding the concatenation in the method? Is the server div even best?</p>
<p>Edit: Forgot to put some of my content sections have simple (limited) html in them already such as paragraph, list... This allows me to easily produce documents for web and printing, I just use different stylesheets.</p>

<pre><code>select a.refnum, b.refnum, c.refnum
from myTable a
left outer join myTable b on (a.contid = b.contid)
left outer join myTable c on (a.contid = c.contid)
where a.id_tp_cd = 90000
and b.id_tp_cd = 10000
and c.id_tp_cd = 20000
</code></pre>
<p>so the values should be:</p>
<pre><code>1, null, 6
2, 4, 7
3, 5, 8
</code></pre>
<p>but its only returning:</p>
<pre><code>2, 4, 7
3, 5, 8
</code></pre>
<p>i thought left joins would show all values in the left and create a null for the right.</p>
<p>help :(</p>

362,560 | <p>In a nutshell: I want to do the same thing "Dependency Walker" does.</p>
<p>Is there any Win32 API function which can enumerate the dependencies of a EXE and/or DLL file?</p>
<p>And is there any safe way to detect dependencies on ActiveX classes? (I doubt it is possible, but who knows ...)</p>
<p><strong>EDIT:</strong> I'm aware of available tools which provide the same core functionality (Dependency Walker, ProcessExplorer, AQTime, ...) but I want to create my own program which dumps a text file containing the required modules. </p>

362,618 | <p>Among the data my application sends to a third-party SOA server are complex XMLs. The server owner does provide the XML schemas (<code>.xsd</code>) and, since the server rejects invalid XMLs with a meaningless message, I need to validate them locally before sending.</p>
<p>I could use a stand-alone XML schema validator but they are slow, mainly because of the time required to parse the schema files. So I wrote my own schema validator (in Java, if that matters) in the form of an <em>HTTP Server</em> which caches the already parsed schemas.</p>
<p>The problem is: many things can go wrong in the course of the validation process. Other than unexpected exceptions and successful validation:</p>
<ul>
<li>the server may not find the schema file specified</li>
<li>the file specified may not be a valid schema file</li>
<li>the XML is invalid against the schema file</li>
</ul>
<p>Since it's an HTTP Server I'd like to provide the client with meaningful <em>status codes</em>. Should the server answer with a <em>400</em> error (<em>Bad request</em>) for all the above cases? Or they have nothing to do with HTTP and it should answer <em>200</em> with a message in the body? Any other suggestion?</p>
<p><em>Update</em>: the main application is written in <em>Ruby</em>, which doesn't have a good xml schema validation library, so a separate validation server is not over-engineering.</p>

362,632 | <p>the other day a colleague of mine stated that using static classes can cause performance issues on multi-core systems, because the static instance cannot be shared between the processor caches. Is that right? Are there some benchmarks around proofing this statement? This statement was made in the context of .Net development (with C#) related discussion, but it sounds to me like a language and environment independent problem.</p>

362,674 | <p>I am trying to work out the overhead of the ASP.NET auto-naming of server controls. I have a page which contains 7,000 lines of HTML rendered from hundreds of nested ASP.NET controls, many of which have id / name attributes that are hundreds of characters in length. </p>
<p>What I would ideally like is something that would extract every HTML attribute value that begins with "ctl00" into a list. The regex Find function in Notepad++ would be perfect, if only I knew what the regex should be?</p>
<p>As an example, if the HTML is:<br>
<input name="ctl00$Header$Search$Keywords" type="text" maxlength="50" class="search" /></p>
<p>I would like the output to be something like:<br>
name="ctl00$Header$Search$Keywords"<br>
A more advanced search might include the element name as well (e.g. control type):<br>
input|name="ctl00$Header$Search$Keywords" </p>
<p>In order to cope with both Id and Name attributes I will simply rerun the search looking for Id instead of Name (i.e. I don't need something that will search for both at the same time).</p>
<p>The final output will be an excel report that lists the number of server controls on the page, and the length of the name of each, possibly sorted by control type.</p>

362,737 | <p>I am developing an interface that takes as input an encrypted byte stream -- probably a very <em>large</em> one -- that generates output of more or less the same format.</p>
<p>The input format is this:</p>
<pre><code>{N byte envelope}
- encryption key IDs &c.
{X byte encrypted body}
</code></pre>
<p>The output format is the same.</p>
<p>Here's the usual use case (heavily pseudocoded, of course):</p>
<pre><code>Message incomingMessage = new Message (inputStream);
ProcessingResults results = process (incomingMessage);
MessageEnvelope messageEnvelope = new MessageEnvelope ();
// set message encryption options &c. ...
Message outgoingMessage = new Message ();
outgoingMessage.setEnvelope (messageEnvelope);
writeProcessingResults (results, message);
message.writeToOutput (outputStream);
</code></pre>
<p>To me, it seems to make sense to use the same object to encapsulate this behaviour, but I'm at a bit of a loss as to how I should go about this. It isn't practical to load all of the encrypted body in at a time; I need to be able to stream it (so, I'll be using some kind of input stream filter to decrypt it) but at the same time I need to be able to write out new instances of this object. What's a good approach to making this work? What should <code>Message</code> look like internally?</p>

<p>I have approximately 35 websites and I can't afford browsing the websites one by one....</p>

362,740 | <p>For years and years, I've tried to understand the <a href="http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.4" rel="noreferrer">part</a> of Java specification that deals with memory model and concurrency. I have to admit that I've failed miserably. Yes' I understand about locks and "synchronized" and wait() and notify(). And I can use them just fine, thank you. I even have a vague idea about what "volatile" does. But all of that was not derived from the language spec - rather from general experience.</p>
<p>Here are two sample questions that I am asking. I am not so much interested in particular answers, as I need to understand how the answers are derived from the spec (or may be how I conclude that the spec has no answer).</p>
<ul>
<li>What does "volatile" do, exactly?</li>
<li>Are writes to variable atomic? Does it depend on variable's type?</li>
</ul>

362,748 | <p>I have a product registration form that allows the user to add additional product fields by clicking "add product". When the user clicks add product, Javascript creates new product field in an existing div.</p>
<p>I currently allow up to 10 products to be added on the form, so I setup a div structure like this:</p>
<pre><code><div id="product1"></div>
<div id="product2"></div>
<div id="product3"></div> etc...
</code></pre>
<p>I have one empty div for each product box that may be added by the user. I use Javascript's innerHTML method to populate the divs.</p>
<p>On to my question: How can I allow an unlimited number of products to be added at once? Obviously, my current setup won't support this since I need to hard code separate div's for each potential product so Javascript has a specific place to drop more data. </p>
<p>NOTE: Before someone suggests using a single div and appending new data into it, that doesn't work. Sadly, all data entered in previous fields is cleared whenever another field is added to the div by appending data like this: </p>
<pre><code>document.getElementById('product').innerHTML += <input name="product">
</code></pre>

<ol>
<li><p>Do <code>realloc()</code> and <code>memcpy()</code> copy the entries in an array to another in a way faster than just iterating on each element <code>O(N)</code> ? If the answer is yes then what do you think is its complexity ?</p></li>

362,770 | <p>My question is, if an interface that is implemented implicitly by extending a class that already implements it, should be explicitly implemented by the class, if the class wants to advertise the fact, that it fulfills the contract of that interface. </p>
<p>For instance, if you want to write a class, that fulfills the contract of the interface <code>java.util.List</code>. You implement this, extending the class <code>java.util.AbstractList</code>, that already implements the interface <code>List</code>. Do you explicitly declare, that you implement List?</p>
<pre><code>public class MyList extends AbstractList implements List
</code></pre>
<p>Or do you save typing by using the implicit way?</p>
<pre><code>public class MyList extends AbstractList
</code></pre>
<p>Which way is considered better style? What reasons do you have to prefer one way or another? In which situations you would prefer way 1 or way 2?</p>

362,808 | <p>I have a fresh install of django 1.0 and a simple page served from it takes 5 secs to load. On my colleague's computer it takes almost no time.</p>
<p>I start the server using </p>
<pre>
python manage.py testserver
</pre>
<p>I can see each GET request (PNGs and style sheets) take about half a second.</p>
<p>Another weird thing, which I think is related, is that the functional tests for the app run much slower on my machine with MySQL (on order of 100 times slower than on my colleague's machine). When I set the app to use sqlite, they run pretty quickly. I would like to exclaim that sqlite doesn't much change the time it takes to load a page, but it does speed up server startup.</p>
<p>It looks like IO problem, but I don't see general performance problems on my machine, apart from django at least.</p>
<p>Django runs on python2.4, I'm running Vista. I have also checked python2.5.</p>
<p>Thanks ΤΖΩΤΖΙΟΥ, It must totaly be a DNS problem, because the page loads up quickly as soon as
instead of <a href="http://localhost:8000/app" rel="noreferrer">http://localhost:8000/app</a> I go to <a href="http://127.0.0.1:8000/app" rel="noreferrer">http://127.0.0.1:8000/app</a>.</p>
<p>But what could it be caused by? My host file has only two entries:</p>
<pre>
127.0.0.1 localhost
::1 localhost
</pre>

362,830 | <p>I have a circular dependency between two functions. I would like each of these functions to reside in its own dll. Is it possible to build this with visual studio?</p>
<pre><code>foo(int i)
{
if (i > 0)
bar(i -i);
}
</code></pre>
<p>-> should compile into foo.dll</p>
<pre><code>bar(int i)
{
if (i > 0)
foo(i - i);
}
</code></pre>
<p>-> should compile into bar.dll</p>
<p>I have created two projects in visual studio, one for foo and one for bar. By playing with the 'References' and compiling a few times, I managed to get the dll's that I want. I would like to know however whether visual studio offers a way to do this in a clean way.</p>
<p>If foo changes, bar does not need to be recompiled, because I only depend on the signature of bar, not on the implementation of bar. If both dll's have the lib present, I can recompile new functionality into either of the two and the whole system still works.</p>
<p>The reason I am trying this is that I have a legacy system with circular dependencies, which is currently statically linked. We want to move towards dll's for various reasons. We don't want to wait until we clean up all the circular dependencies. I was thinking about solutions and tried out some things with gcc on linux and there it is possible to do what I suggest. So you can have two shared libraries that depend on each other and can be built independent of each other.</p>
<p>I know that circular dependencies are not a good thing to have, but that is not the discussion I want to have.</p>

362,861 | <p>I'm implementing a COM interface that should return int values either <code>S_OK</code> or <code>E_FAIL</code>. I'm ok returning <code>S_OK</code> as I get that back from another call (Marshal.QueryInterface), but if I want to return a failure value what actual value do I use for <code>E_FAIL</code>?</p>
<p>(It's such a basic fundamental question that it's hard to find an answer to)</p>
<p>Assuming it's a specific number defined in the Win32 API, is there way to use it within .net code without declaring my own constant?</p>
<p>thanks!</p>
<p><strong>Update (answered below):</strong></p>
<p>Maybe I'm being a complete plonker, but I'm having problems with this. According to my Platform SDK, <code>HRESULT</code> is a <code>LONG</code>, which is a 32-bit signed integer, right? So possible values –2,147,483,648 to 2,147,483,647. But 0x80004005 = 2,147,500,037 which is > 2,147,483,647. What gives!?</p>
<p>This means when I try to put this in my code:</p>
<pre><code>const int E_FAIL = 0x80004005;
</code></pre>
<p>I get a compiler error <em>Cannot implicitly convert type 'uint' to 'int'</em>.</p>
<p><strong>Update 2:</strong></p>
<p>I'm going to declare it like this:</p>
<pre><code>const int E_FAIL = -2147467259;
</code></pre>
<p>because if I try to do something like this:</p>
<pre><code>const UInt32 E_FAIL = 0x80004005;
return (Int32)E_FAIL;
</code></pre>
<p>I get a compiler error <em>Constant value '2147500037' cannot be converted to a 'int' (use 'unchecked' syntax to override)</em></p>
<p>Phew! Who knew how tricky it would be to declare a standard return value.... Somewhere there must be a class lurking that I should have used like <strong>return Win32ReturnCodes.E_FAIL;</strong> ... <em>sigh</em></p>
<p><strong>ULTIMATE SOLUTION:</strong></p>
<p>I now do this by getting the (massive but very useful) HRESULT enum from <a href="http://www.pinvoke.net/default.aspx/Enums/HRESULT.html" rel="nofollow noreferrer">pinvoke.net</a> and adding it to my solution. Then use it something like this:</p>
<pre><code>return HRESULT.S_OK;
</code></pre>

362,902 | <p>I have a two-page SSRS report. When I exported it to PDF it was taking 4 pages due to its width, where the 2nd and 4th pages were displaying one of my fields from the table. I tried to set the layout size in report properties as width=18in and height =8.5in.</p>
<p>It gave me the whole table in a single page of PDF, but I am still getting the 2nd and 4th pages blank. </p>
<p>Is the way I am doing it incorrect? How else can I get rid of those blank pages?</p>

362,907 | <p>In a custom role provider (inheriting from RoleProvider) in .NET 2.0, the IsUserInRole method has been hard-coded to always return true:</p>
<pre><code>public override bool IsUserInRole(string username, string roleName) { return true; }
</code></pre>
<p>In an ASP.NET application configured to use this role provider, the following code returns true (as expected):</p>
<pre><code>Roles.IsUserInRole("any username", "any rolename"); // results in true
</code></pre>
<p>However, the following code returns false:</p>
<pre><code>Roles.IsUserInRole("any rolename"); // results in false
</code></pre>
<p>Note that User.IsInRole("any rolename") is also returning false.</p>
<ol>
<li>Is this the expected behavior?</li>
<li>Is it incorrect to assume that the overload that only takes a role name would still be invoking the overridden IsUserInRole?</li>
</ol>
<p><strong>Update</strong>: Note that there doesn't seem to be an override available for the version that takes a single string, which has led to my assumption in #2.</p>

362,911 | <p>I'm working with NHibernate and need to retrieve and process up to 2 million rows. Ideally, I could process each row - one at a time - without NHibernate loading all 2 million in memory at once (because, you know, that hurts). </p>
<p>I'd prefer to get an IEnumerable which would call the data reader iteratively for each read so I could process the data read - then discard it. By doing it this way I save a boatload of memory, and begin processing results far faster. I could also improve performance through multithreading and/or the use of PLinq.</p>
<p>Is this possible with NHibernate's ICriteria? Everything it returns seems to be IList, and fully loaded before handing the collection reference off. Why IList instead of IEnumerable?!</p>
<p>I don't mean "lazy" in the traditional sense that NHibernate uses with regards to loading child or parent objects. I want a <strong>lazy IEnumerable meaning someway of getting a IEnumerable from an ICriteria object</strong>. ICriteria only has a List() method which loads the results in an ArrayList.</p>

362,918 | <p>I'm looking for a good pattern to resolve the following circular reference in a Windows Form application:</p>
<ul>
<li>Assembly 1 contains a Windows Form with an Infragistics menu item ".Show"ing a Form in Assembly 2</li>
<li>Assembly 2 contains a Windows Form with an Infragistics menu item ".Show"ing a Form in Assembly 1</li>
</ul>
<p>The menu has generally the same items on it throughout the application. So both Assembly 1 and Assembly 2 have references to one another to "New up" one anothers' forms and .Show them.</p>
<p>A note about size: My app is an existing app, so the situation is not quite as simple as the above two-assembly situation. But if I can solve the above simply (probably not implementing a , I can apply that to a much larger application (about 20 components, all with several forms that pop each other up across components).</p>
<p>I've thought through a few solutions, but they all seem cumbersome. Is there a simple solution I'm missing?</p>

362,948 | <p>I spent several hours yesterday trying to digitally sign a short file using an X509 certificate (one of the "freemail" certificates from thawte). I finally got openssl to sign it as an SMIME message, but I can't successfully verify it, AND it's in the SMIME format -- I don't have access to a "sendmail" program which can actually send out the SMIME file.</p>
<p>I just want to create some file that is "excerptable" via plain cut & paste, like:</p>
<pre><code>===BEGIN SIGNED DOCUMENT===
===BEGIN DOCUMENT===
blah blah blah this is the plaintext ...
===END DOCUMENT===
===BEGIN SIGNATURE===
AFab12121abadAF ...
===END SIGNATURE===
===END SIGNED DOCUMENT===
</code></pre>
<p>Alternatively I guess I could make a .zip file that contains the original file and also the signature.</p>
<p>so I guess my requirements are:</p>
<ol>
<li>input plaintext = arbitrary file</li>
<li>input signkey = from X509 certificate</li>
<li>output = something I can easily email to someone else by cut&paste or by attaching a single .zip file</li>
<li>program = something that is free & open source like openssl or gpg</li>
<li>program != a magic GUI where I don't understand what's going on</li>
<li>ability to easily use the program to generate output from inputs</li>
<li>ability to easily extract the plaintext from the output (e.g. either directly by eye or as a component of the .zip file)</li>
<li>ability to verify that the plaintext was signed by the grantee of the X509 certificate (i.e. me) and that the grantor (CA) of the certificate is a Well-Known CA... assuming that I am a rational person who keeps the certificate secure from use by other parties (otherwise someone could sign things as me).</li>
</ol>
<p>Is there a good tutorial for X509 certificates & how they are used in practice for this stuff? I have the 2nd edition of Schneier's "Applied Cryptography" & have a fair amount of experience with cryptographic algorithms + protocols, but don't know much at all about X509 and I'm really confused as to what a certificate actually is in practical terms. (In other words, "a certificate is a cryptographic assertion by the issuing party CA that the party X named in the certificate is an identity known to the CA?" AND "a certificate enables its bearer to _____")</p>
<p>When I get one it shows up in Firefox's "Your Certificates" tab of the Certificate Manager, and I can export it and read it with openssl, but I want to make sure that it's not stored in any way that someone else can use it w/o knowing the cert. passphrase -- and I get really confused because it seems like some certificates only have the public key & others have encrypted private keys.</p>
<p>Is there a good, simple GUI wrapper around openssl that allows you to have it explain what it's doing?</p>
<hr>
<p><strong>edit:</strong> thawte doesn't easily let you use certificate requests directly; instead it talks to web browsers (I use Firefox) & that generatese the private key and handles all the certificate protocol. So I can export that as a PKCS12 file but am not exactly sure how to use that.</p>

362,953 | <p>I just learned about the C++ construct called "placement new". It allows you to exactly control where a pointer points to in memory. It looks like this:</p>
<pre><code> #include <new> // Must #include this to use "placement new"
#include "Fred.h" // Declaration of class Fred
void someCode()
{
char memory[sizeof(Fred)];
void* place = memory;
Fred* f = new(place) Fred(); // Create a pointer to a Fred(),
// stored at "place"
// The pointers f and place will be equal
...
}
</code></pre>
<p>(example from <a href="http://www.parashift.com/c++-faq-lite/dtors.html#faq-11.10" rel="noreferrer" title="C++ FAQ Lite">C++ FAQ Lite</a>)<br><br>
In this example, the <code>this</code> pointer of Fred will be equal to <code>place</code>.</p>
<hr>
<p>I've seen it used in our team's code once or twice. In your experience, what does this construct enable? Do other pointer languages have similar constructs? To me, it seems reminiscent of <code>equivalence</code> in FORTRAN, which allows disparate variables to occupy the same location in memory.</p>

362,955 | <p>Is it a good idea to have a factory class using generics to instantiate objects?</p>
<p>Let's say I have a class Animal and some subclasses (Cat, Dog, etc):</p>
<pre><code>abstract class Animal
{
public abstract void MakeSound();
}
class Cat : Animal
{
public override void MakeSound()
{
Console.Write("Mew mew");
}
}
class Dog : Animal
{
public override void MakeSound()
{
Console.Write("Woof woof");
}
}
static class AnimalFactory
{
public static T Create<T>() where T : Animal, new()
{
return new T();
}
}
</code></pre>
<p>Then in my code I would use AnimalFactory like this:</p>
<pre><code>class Program
{
static void Main(string[] args)
{
Dog d = AnimalFactory.Create<Dog>();
d.MakeSound();
}
}
</code></pre>

<p>My Gsp code is:</p>
<pre><code><g:uploadForm action="saveImage">

flash.message = 'Image uploaded'
redirect(action: 'uploadImage')

<p>In this code if i upload some other files like text files it throws Exception.For that i want to check the file Extension and I want to use If loop that ensures the uploaded file is image file or not.But i dont know how to find the file extension in grails.</p>
<p>Is there any other way to upload images in grails application.It has to accept only image files.</p>
<p>can anyone provide help?</p>

362,979 | <p>As the name suggests I am trying to group rows in a datatable. To go into further detail this table has identical rows except for one field(column). Basically what I am trying to do is put all the different fields of the identical rows and put them in single field whilst deleting the other rows.</p>
<p>Here is the syntax that I am currently using</p>
<pre><code> Dim i As Integer
Dim j As Integer
For i = 0 To (ds.Tables(0).Rows.Count() - 1) Step 1
If (i < ds.Tables(0).Rows.Count()) Then
roleHtml = "<table><tr><td>" + ds.Tables(0).Rows(i).Item("roleName") + "</td></tr>"
For j = (ds.Tables(0).Rows.Count() - 1) To 0 Step -1
If (ds.Tables(0).Rows(i).Item("UserName") = ds.Tables(0).Rows(j).Item("UserName")) And (ds.Tables(0).Rows(i).Item("roleName") IsNot ds.Tables(0).Rows(j).Item("roleName")) Then
roleHtml += "<tr><td>" + ds.Tables(0).Rows(j).Item("roleName") + "</td></tr>"
ds.Tables(0).Rows.Remove(ds.Tables(0).Rows(j))
i -= 1
End If
Next j
roleHtml += "</table>"
ds.Tables(0).Rows(i).Item("roleName") = roleHtml
End If
Next i
</code></pre>
<p>The problem is when deleting the rows their index changes and basically the field gets thrown in another row that has nothing to do with it.</p>

362,983 | <p>I am trying to get a list of all unit test assemblies under the root of my project. I can do this as follows:</p>
<pre><code><CreateItem Include="**\bin\**\*.UnitTest.*.dll">
<Output TaskParameter="Include" ItemName="Items"/>
</CreateItem>
</code></pre>
<p>However, this will find the same DLLs multiple times since they exist in multiple sub-directories. Is there an easy way for me to normalize based on item metadata (ie. the file name and extension) so that I get a list of unique unit test DLLs? Or do I have to resort to writing my own task?</p>

362,993 | <p>I'm developing a basic dip-switch user control as a personal learning exercise. Originally I had it set up where you could declare some custom color properties on the user control, and they would be used on elements inside the control.</p>
<p>However, I recenly discovered ToggleButtons, and rebuilt my control to take advantage of them. Since then, my custom color properties (SwitchColor and SwitchBkgndColor) no longer work properly. They are always rendered with the default colors, not the colors I specified when I place them in my Window. Here's some code:</p>
<pre><code> <UserControl x:Class="DipSwitchToggleBtn"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:app="clr-namespace:SwitchesApp"
Width="20" Height="40">
<ToggleButton Name="ToggleBtn" IsThreeState="False">
<ToggleButton.Template>
<ControlTemplate>
<Canvas Name="SwitchBkgnd"
Background="{TemplateBinding app:DipSwitchToggleBtn.SwitchBkgndColor}"
>
<Rectangle Name="SwitchBlock"
Fill="{TemplateBinding app:DipSwitchToggleBtn.SwitchColor}"
Width="16" Height="16"
Canvas.Top="22"
Canvas.Left="2"
/>
</Canvas>
<ControlTemplate.Triggers>
<Trigger Property="ToggleButton.IsChecked" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SwitchBlock"
Duration="00:00:00.05"
Storyboard.TargetProperty="(Canvas.Top)" To="2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SwitchBlock"
Duration="00:00:00.05"
Storyboard.TargetProperty="(Canvas.Top)" To="22" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</ToggleButton.Template>
</ToggleButton>
</UserControl>
</code></pre>
<p>...and the code behind:</p>
<pre><code>Partial Public Class DipSwitchToggleBtn
Public Property State() As Boolean
Get
Return Me.ToggleBtn.IsChecked
End Get
Set(ByVal value As Boolean)
Me.ToggleBtn.IsChecked = value
End Set
End Property
Public Sub Toggle()
Me.State = Not Me.State
End Sub
#Region " Visual Properties "
Public Shared ReadOnly SwitchColorProperty As DependencyProperty = _
DependencyProperty.Register("SwitchColor", _
GetType(Brush), GetType(DipSwitchToggleBtn), _
New FrameworkPropertyMetadata(Brushes.LightGray))
Public Property SwitchColor() As Brush
Get
Return GetValue(SwitchColorProperty)
End Get
Set(ByVal value As Brush)
SetValue(SwitchColorProperty, value)
End Set
End Property
Public Shared ReadOnly SwitchBkgndColorProperty As DependencyProperty = _
DependencyProperty.Register("SwitchBkgndColor", _
GetType(Brush), GetType(DipSwitchToggleBtn), _
New FrameworkPropertyMetadata(Brushes.Gray))
Public Property SwitchBkgndColor() As Brush
Get
Return GetValue(SwitchBkgndColorProperty)
End Get
Set(ByVal value As Brush)
SetValue(SwitchBkgndColorProperty, value)
End Set
End Property
#End Region
End Class
</code></pre>
<p>The default Gray and LightGray show up in the VS2008 designer and the compiled app, but when I do something like this in my window:</p>
<pre><code><app:DipSwitchToggleBtn x:Name="DipSwitchTest" SwitchColor="#0000FF" SwitchBkgndColor="#000000" />
</code></pre>
<p>The colors I specified for this instance do not get used. Everything compiles without error, but my control is still displayed with the default colors.</p>
<p>I believe there is some new hierarchy at play since I nested my items in the ToggleButton.</p>
<p>Any help would be appreciated. Thank you.</p>

363,026 | <p>I have the following linq code...</p>
<pre><code>CMSDataContext dc = new CMSDataContext();
var q = from u in dc.CMSUsers
join d in dc.tblDistricts
on u.DistrictCode equals d.District into orders
select u;
</code></pre>
<p>District shows this error:
Ambiguity between 'tblDistrict.District' and 'tblDistrict.District'</p>
<p>Any ideas?</p>
<p>EDIT:</p>
<p>It turns out that I had the same table in two different dbml files. Apparently, I cannot do this. I will have to end up joining a table from one dbml file with another table from a different dbml file. If anyone can enlighten me on how to do this, I will deem it as an answer. Thanks.</p>

363,031 | <p>I want to open a ZIP-file, that have no entries with java.util.zip.ZipFile. But on the constructor I get the following exception: 'java.util.zip.ZipException: error in opening zip file'. How can I open the empty ZIP?</p>
<p>That ZIP-file is created by the commandline zip-program under linux. I simply deleted all entries from a ZIP-file.</p>
<p>I need this as testdata for a class I write. The class should simply return an empty list for this case, but broken ZIP-files should return an error.</p>
<p>For some more explanation on the problem. I have an interface, for extracting some documents from different sources. Other implementations gather them from webservices or directories, this implementation from ZIP-files. The interface give an Iterator with some more functionality. So I want to decide, if the ZIP-file is empty or broken.</p>

363,038 | <p>I am messing around with different PHP logging frameworks. I am currently trying PEAR::Log. I figured that I would use its <code>singleton</code> function to make sure there was only one instance of the class around.</p>
<p>I have a small daemon-like script I wanted to add logging to because it was probably the simplest script in the system to test. This script has several functions. I will probably want to log things inside the functions.</p>
<p>The question I have is how do I best manage this singleton? </p>
<p>To me calling this:</p>
<pre><code>&Log::singleton($handler, $name, $ident, $conf, $maxLevel);
</code></pre>
<p>in every function doesn't seem ideal especially since I already specified all of the options in the initial call. Pear::Log serializes this info, but from what it looks like you still have to provide all of those variables to get the instance.</p>
<p>Another alternative is passing the instance into every function. Again, seems like it's less than ideal.</p>
<p>I suppose you could make the instance a 'global' as well.</p>
<p>What do you in this situation? Are there better solutions? </p>

363,086 | <p>I want to create custom tooltips where I can put any kind of controls. I have derived from CDialog and used the <code>WS_POPUP | WS_BORDER</code> styles. I also add the <code>CS_DROPSHADOW</code> style in the OnInitDialog to get the tooltip shadow.</p>
<p>Then I manage myself the <code>WM_MOUSEHOVER</code> and <code>WM_MOUSELEAVE</code> events to show/hide the tooltips.</p>
<p>I display the tooltip using <code>SetWindowPos</code> and <code>SWP_NOACTIVATE</code> to prevent the parent from becoming inactive and the new dialog from becoming active. But anyway, when I create the dialog using <code>CDialog::Create</code> method...the main window becomes inactive...what makes a very bad effect.</p>
<p>So my custion is how can I create a CDialog with the WS_POPUP style without my main window (or the parent window of the dialog) becomening inactive when the new dialog shows up???</p>
<p>Thanks for helping!</p>
<p>Edited: I do not use the WS_VISIBLE style to create the dialog...this this the resource:</p>
<pre><code> IDD_LABEL_TOOLTIP_DLG DIALOGEX 0, 0, 100, 9
STYLE DS_SETFONT | WS_POPUP | WS_BORDER
FONT 8, "Tahoma", 0, 0, 0x0
BEGIN
LTEXT "##################",IDC_TOOLTIP_LBL_TEXT,0,0,99,9
END
</code></pre>
<p>The code that display the tooltip is something like that:</p>
<pre><code>if(!pTooltipDlg)
{
pTooltipDlg = new MyCustomTooltipDlg();
pTooltipDlg->Create( MyCustomTooltipDlg::IDD, this);
}
pTooltipDlg->ShowWindow(SW_SHOWNOACTIVATE);
</code></pre>
<p>The first time (ie when the create is being call) the main windows lose the focus...the rest of them this ugly effect is not happening...so I am sure is because of the Create.</p>

363,099 | <p>I am using <a href="http://msdn.microsoft.com/en-us/library/system.drawing.graphics.fillpolygon.aspx" rel="nofollow noreferrer">FillPolygon</a> with a semi-transparent color to draw a triangle (an arrow pointer). I have noticed that FillPolygon gives awkward results with an isocel triangle. One of the sides is overlapping <a href="http://msdn.microsoft.com/en-us/library/system.drawing.graphics.drawpolygon.aspx" rel="nofollow noreferrer">DrawPolygon</a>'s side, while the two others aren't. I would have expected none or all, but not something in between.</p>
<p>Here's a sample: DrawPolygon uses a semi-transparent red, while FillPolygon uses a semi-transparent green. You can see one side is brown, the two other sides are red.</p>
<p><a href="http://www.slimcode.com/downloads/arrow.png" rel="nofollow noreferrer">alt text http://www.slimcode.com/downloads/arrow.png</a></p>
<p>The coordinates for this example are: {X=36,Y=201}, {X=42,Y=207}, {X=30,Y=207}.</p>
<p>Using an opaque color would solve everything as I could call both DrawPolygon and FillPolygon, but I need to use a semi-transparent color. I'm drawing into an image if it can make a difference.</p>

363,111 | <p>I use Vim and Vim plugins for Visual Studio when writing C++. Often, I find myself wanting to search for a string within a function, for example every call to <code>object->public_member.memberfunc()</code>.</p>
<p>I know Vim offers a convenient way to search for a single word, by pressing <code>*</code> and <code>#</code>, and it can also search for typed strings using the ubiquitous slash <code>/</code> command. When trying to search for all the instances of a longer string like the one above, it takes a while to re-type after <code>/</code>.</p>
<p>Is there a way to search for the selection? For example, highlight with <code>v</code>, then copy with <code>y</code>, is there a way to paste after <code>/</code>? Is there an easier shortcut?</p>

363,189 | <p>I have a sql statement that consists of multiple SELECT statements. I want to limit the total number of rows coming back to let's say 1000 rows. I thought that using the SET ROWCOUNT 1000 directive would do this...but it does not. For example:</p>
<pre><code>SET ROWCOUNT 1000
select orderId from TableA
select name from TableB
</code></pre>
<p>My initial thought was that SET ROWCOUNT would apply to the <strong>entire</strong> batch, not the individual statements within it. The behavior I'm seeing is it will limit the first select to 1000 and then the second one to 1000 for a total of 2000 rows returned. Is there any way to have the 1000 limit applied to the batch as a whole?</p>

363,200 | <p>I have a QTreeWidget with a column filled with some numbers, how can I sort them?</p>
<p>If I use setSortingEnabled(true); I can sort correctly only strings, so my column is sorted:</p>
<p>1
10
100
2
20
200</p>
<p>but this is not the thing I want!
Suggestions?</p>

363,209 | <p>I would like to know if it is possible to copy/move files to a destination based on the origin name.</p>
<p>Basically, I have a /mail folder, which has several subfolders such as cur and new etc. I then have an extracted backup in /mail/home/username that is a duplicate. mv -f will not work, as I do not have permission to overwrite the directories, but only the files within.</p>
<p>I get errors such as mv: cannot overwrite directory `/home/username/mail/username.com'</p>
<p>What I want to do is for each file in the directory username.com, move it to the folder of the same name in /mail. There could be any number of folders in place of username.com, with seperate sub sirectories of their own.</p>
<p>What is the best way to do this?</p>
<p>I have to do it this way as due to circumstances I only have access to my host with ftp and bash via php.</p>
<p>edit: clarification</p>
<p>I think I need to clarify what happened. I am on a shared host, and apparently do not have write access to the directories themselves. At least the main ones such as mail and public_html. I made a backup of ~/mail with tar, but when trying to extract it extracted to ~/mail/home/mail etc, as I forgot about the full path. Now, I cannot simply untar because the path is wrong, and I cannot mv -f because I only have write access to files, not directories.</p>

363,211 | <p>ASP.NET MVC routes have names when mapped:</p>
<pre><code>routes.MapRoute(
"Debug", // Route name -- how can I use this later????
"debug/{controller}/{action}/{id}",

<p>Is there a way to get the route name, e.g. "Debug" in the above example? I'd like to access it in the controller's OnActionExecuting so that I can set up stuff in the ViewData when debugging, for example, by prefixing a URL with /debug/...</p>

363,223 | <p>I have a script which will be run interactively by non-technical users. The script writes status updates to STDOUT so that the user can be sure that the script is running OK.</p>
<p>I want both STDOUT and STDERR redirected to the terminal (so that the user can see that the script is working as well as see if there was a problem). I also want both streams redirected to a log file.</p>
<p>I've seen a bunch of solutions on the net. Some don't work and others are horribly complicated. I've developed a workable solution (which I'll enter as an answer), but it's kludgy.</p>
<p>The perfect solution would be a single line of code that could be incorporated into the beginning of any script that sends both streams to both the terminal and a log file.</p>
<p><strong>EDIT:</strong> Redirecting STDERR to STDOUT and piping the result to tee works, but it depends on the users remembering to redirect and pipe the output. I want the logging to be fool-proof and automatic (which is why I'd like to be able to embed the solution into the script itself.)</p>

363,231 | <p>i'm using ASP.net with .NET 3.5 on IIS7 (Vista) with the URL Rewrite Module from Microsoft.</p>
<p>This means, that i have a </p>
<pre><code><system.webServer>
<rewrite>...</rewrite>
...
</system.webServer>
</code></pre>
<p>section within the web.config, but i get a warning, that within the system.webServer the element "rewrite" is not allowed.</p>
<p>How can i configure my system to allow (and maybe even have Intellisense) on the rewrite-part of the web.config?</p>
<p>Thank you
Christoph</p>

363,234 | <p>Is it possible to get a URL from an action without knowing ViewContext (e.g., in a controller)? Something like this:</p>
<pre><code>LinkBuilder.BuildUrlFromExpression(ViewContext context, Expression<Action<T>> action)
</code></pre>
<p>...but using Controller.RouteData instead of ViewContext. I seem to have metal block on this.</p>

363,244 | <p>I chose AjaxToolKit to build a WebForm login. Has anyone else had problems trying to do this? I'm planning to use DropShadow Extender and RoundedCorners with Panels, but this is my first time working with panels.</p>
<p>Please check <a href="http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ConfirmButton/ConfirmButton.aspx" rel="nofollow noreferrer">this link</a>.</p>
<p>I want to put a login panel into something like the screenshot shows, whenever the user clicks a button. This would be similar functionality to what happens on StackOverflow when you try to insert an image or hyperlink in 'ask a question'. Is this possible? How much effort is it?</p>

363,268 | <p>I'm using the jQuery validation plugin to validate a form, and I'd like to remove the validation and submit the form if a certain link is clicked.</p>
<p>I am submitting form with javascript like <code>jQuery('form#listing').submit()</code>, so I must remove the validation rules/function with javascript.</p>
<p>The problem is that I can't figure out how to do this. I've tried things like <code>jQuery('form#listing').validate({});</code> and <code>jQuery('form#listing').validate = null</code>, but with no luck.</p>

363,276 | <p>How can I hide the div without using <code>display:none</code> or JavaScript?</p>
<p>In my country, a lot of Blackberrys come with the CSS support disabled (the mobile companies here are not so good to developers). I have text that says</p>
<pre><code><div class="BBwarn">
please activate your css support and a link
</div>
</code></pre>
<p>I want to hide that once the user activates CSS support, but i can't use <code>display:none;</code> because it is only supported in BB firmware 4.6. It is a public site and I can't make all my visitors upgrade.</p>
<p>Does anybody knows a solution to this? I hope the question is easier to understand now.</p>
<p>Update:
Thank you all for the answers but I can't use </p>
<ul>
<li>position:absolute</li>
<li>overflow</li>
</ul>
<p>because they are available from Blackberry firmware 4.6 and up</p>

363,295 | <p>I'm trying to follow code-to-interface on a project. Should I be creating an interface first then implementing that interface for entity classes? I'm thinking this might be taking the interface first approach too far and entities should be ignored. This is what I mean...</p>
<pre><code>public interface Address {
public String getStreet();
public void setStreet(String street);
}
@Entity
public class AddressImpl implements Address {
private String street;
public String getStreet(){
return this.street;
}
public void setStreet(String street){
this.street = street;
}
}
@Entity
public class OfficeImpl /* implements Office */ {
private Address location;
public Address getLocation(){
return this.location;
}
public void setLocation(Address location){
this.location = location;
}
}
public class Driver {
public static void main(String[] args) {
Office work = new OfficeImpl();
Address workAddress = new AddressImpl();
workAddress.setStreet("Main St.");

363,302 | <p>I'm trying to display a picture in an openGL environment. The picture's origninal dimensions are 3648x2432, and I want to display it with a 256x384 image. The problem is, 384 is not a power of 2, and when I try to display it, it looks stretched. How can I fix that?</p>

363,320 | <p>I've seen the designer code, and I have seen code which builds the ObjectDataSource in the code-behind, however both methods communicate directly with the database via either text commands or stored procs. This seems like unnecessary code duplication to me since my data access layer has a method already which returns a datatable with the data I need for this report. </p>
<p>How can I programmatically build and link the ODS to my data access layer's method?</p>
<p>EDIT: </p>
<p>Thanks to everyone who answered. This was very poorly phrased on my part. There was too much that I did not understand when I wrote this question originally. What I should have asked is: </p>
<p>How do I programmatically bind a .Net Reporting Services Report (*.rdlc) to a method in my Data Access Layer instead of an ADO.Net DataSet.</p>
<p>See my answer below. </p>

363,325 | <p>I would like to parse a document using SAX, and create a subdocument from some of the elements, while processing others purely with SAX. So, given this document:</p>
<pre><code> <DOC>
<small>
<element />
</small>
<entries>
<!-- thousands here -->
</entries>
</DOC>
</code></pre>
<p>I would like to parse the DOC and DOC/entries elements using the SAX ContentHandler, but when I hit <code><small></code> I want to create a new document containing just the <code><small></code> and its children.</p>
<p>Is there an easy way to do this, or do I have to build the DOM myself, by hand?</p>

363,336 | <p>This is driving me nuts. I am using some 3rd-party code in a Windows .lib that, in debug mode, is causing an error similar to the following:</p>
<pre><code>Run-Time Check Failure #2 - Stack around the variable 'foo' was corrupted.
</code></pre>
<p>The error is thrown when either the object goes out of scope or is deleted. Simply allocating one of these objects and then deleting it will throw the error. I therefore think the problem is either in one of the many constructors/destructors but despite stepping through every line of code I cannot find the problem.</p>
<p>However, this only happens when creating one of these objects in a static library. If I create one in my EXE application, the error does not appear. The 3rd-party code itself lives in a static lib. For example, this fails:</p>
<pre><code>**3RDPARTY.LIB**
class Foo : public Base
{
...
};
**MY.LIB**
void Test()
{
Foo* foo = new Foo;
delete foo; // CRASH!
}
**MY.EXE**
void Func()
{
Test();
}
</code></pre>
<p>But this will work:</p>
<pre><code>**3RDPARTY.LIB**
class Foo : public Base
{
...
};
**MY.EXE**
void Func()
{
Foo* foo = new Foo;
delete foo; // NO ERROR
}
</code></pre>
<p>So, cutting out the 'middle' .lib file makes the problem go away and it is this weridness that is driving me mad. The EXE and 2 libs all use the same CRT library. There are no errors linking. The 3rd-party code uses inheritance and there are 5 base classes. I've commented out as much code as I can whilst still getting it to build and I just can't see what's up.</p>
<p>So if anyone knows why code in a .lib would act differently to the same code in a .exe, I would love to hear it. Ditto any tips for tracking down memory overwrites! I am using Visual Studio 2008.</p>

363,341 | <p>As someone in the world of <a href="http://en.wikipedia.org/wiki/High-performance_computing" rel="noreferrer">HPC</a> who came from the world of enterprise web development, I'm always curious to see how developers back in the "real world" are taking advantage of parallel computing. This is much more relevant now that <a href="http://www.gotw.ca/publications/concurrency-ddj.htm" rel="noreferrer">all chips are going multicore</a>, and it'll be even more relevant when there are thousands of cores on a chip instead of just a few.</p>
<p>My questions are: </p>
<ol>
<li>How does this affect your software roadmap?</li>
<li>I'm particularly interested in real stories about how multicore is affecting different software domains, so specify what kind of development you do in your answer (<em>e.g.</em> server side, client-side apps, scientific computing, etc).</li>
<li>What are you doing with your existing code to take advantage of multicore machines, and what challenges have you faced? Are you using <a href="http://www.openmp.org/" rel="noreferrer">OpenMP</a>, <a href="http://www.erlang.org/" rel="noreferrer">Erlang</a>, <a href="http://www.haskell.org/" rel="noreferrer">Haskell</a>, <a href="http://en.wikipedia.org/wiki/CUDA" rel="noreferrer">CUDA</a>, <a href="http://www.threadingbuildingblocks.org/" rel="noreferrer">TBB</a>, <a href="http://upc.lbl.gov/" rel="noreferrer">UPC</a> or something else?</li>
<li>What do you plan to do as concurrency levels continue to increase, and how will you deal with hundreds or thousands of cores?</li>
<li>If your domain <em>doesn't</em> easily benefit from parallel computation, then explaining why is interesting, too.</li>
</ol>
<p>Finally, I've framed this as a multicore question, but feel free to talk about other types of parallel computing. If you're porting part of your app to use <a href="http://labs.google.com/papers/mapreduce.html" rel="noreferrer">MapReduce</a>, or if <a href="http://www.open-mpi.org/" rel="noreferrer">MPI</a> on large clusters is the paradigm for you, then definitely mention that, too.</p>
<p><strong>Update:</strong> If you do answer #5, mention whether you think things will change if there get to be more cores (100, 1000, etc) than you can feed with available memory bandwidth (seeing as how bandwidth is getting smaller and smaller per core). Can you still use the remaining cores for your application?</p>

363,370 | <p>I'm writing a database application that connects to SQL server. I'd like to implement a similar connection dialog box like the one in SQL Management Studio. I've already found a way to get the list of databases on a server, but I'd really like to get the list of available servers on the network so end users won't have to type in the name/IP of the server.</p>

363,377 | <p>I have a bit of code that I need to run in a different thread than the GUI as it currently causes the form to freeze whilst the code runs (10 seconds or so). </p>
<p>Assume I have never created a new thread before; what's a simple/basic example of how to do this in C# and using .NET Framework 2.0 or later? </p>

363,425 | <p>If a user types in a long line without any spaces or white space, it will break formating by going wider than the current element. Something like:</p>
<blockquote>
<p>HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA.............................................................................................................................................</p>
</blockquote>
<p>I've tried just using <code>wordwrap()</code> in PHP, but the problem with that is if there is a link or some other valid HTML, it breaks.</p>
<p>There seems to be a few options in CSS, but none of them work in all browsers. See word-wrap in IE.</p>
<p>How do you solve this problem?</p>

363,453 | <p>I have an application that has several objects (about 50 so far, but growing). There is only one instance of each of these objects in the app and these instances get shared among components.</p>
<p>What I've done is derive all of the objects from a base BrokeredObject class:</p>
<pre><code>class BrokeredObject
{
virtual int GetInterfaceId() = 0;
};
</code></pre>
<p>And each object type returns a unique ID. These IDs are maintained in a header file.</p>
<p>I then have an ObjectBroker "factory". When someone needs an object, then call GetObjectByID(). The boker looks in an STL list to see if the object already exists, if it does, it returns it. If not, it creates it, puts it in the list and returns it. All well and good.</p>
<pre><code>BrokeredObject *GetObjectByID(int id)
{
BrokeredObject *pObject;
ObjectMap::iterator = m_objectList.find(id);
// etc.
if(found) return pObject;
// not found, so create
switch(id)
{
case 0: pObject = new TypeA; break;
case 1: pObject = new TypeB; break;
// etc.
// I loathe this list
}
// add it to the list
return pObject;
}
</code></pre>
<p>What I find painful is maintaining this list of IDs and having to have each class implement it. I have at least made my consumer's lives slightly easier by having each type hold info about it's own ID like this:</p>
<pre><code>class TypeA : public BrokeredObject
{
static int get_InterfaceID() { return IID_TYPEA; }
int GetInterfaceID() { return get_InterfaceID(); }
};
</code></pre>
<p>So I can get an object like this:</p>
<pre><code>GetObjectByID(TypeA::get_InterfaceID());
</code></pre>
<p>Intead of having to actually know what the ID mapping is but I still am not thrilled with the maintenance and the potential for errors. It seems that if I know the type, why should I also have to know the ID?</p>
<p>What I long for is something like this in C#:</p>
<pre><code>BrokeredObject GetOrCreateObject<T>() where T : BrokeredObject
{
return new T();
}
</code></pre>
<p>Where the ObjectBroker would create the object based on the <em>type</em> passed in.</p>
<p>Has C# spoiled me and it's just a fact of life that C++ can't do this or is there a way to achieve this that I'm not seeing?</p>

363,465 | <p>So I totally buy into the basic tenents of ASP.NET, testability, SoC, HTML control...it's awesome. However being new to it I have a huge hang up with the markup. I know it comes from my hatred of classic ASP, and I can't help but feel like I've entered the twilight zone when <a href="http://www.flickr.com/photos/webjedi/3103009542/" rel="noreferrer">I see this</a>.</p>
<p>I don't know what the alternative is (can I use server controls, databinding etc...?)</p>

363,491 | <p>I have this PHP code</p>
<pre><code>echo '<a href="#" onclick="updateByQuery(\'Layer3\', ' . json_encode($query) . ');">Link 1</a>';
</code></pre>
<p>which generates a link like this:</p>
<pre><code><a href="#" onclick="updateByQuery('Layer3', "Ed Hardy");">Link 1</a><li>Link 2</li>
</code></pre>
<p>Causing the javascript to not be called. How would I make it generate single quotes around the result of $query, in this case ed hardy?</p>

363,504 | <p>I want to have a abstract view for any type of UI (web or window). In order to do that I must use Interface (IView ) in which I can only apply just rules about view. In fact, I want to set a some basic comple function to provide to its inheritances.</p>
<p>So in this way, I must use abstract class. The problem is</p>
<p>1) Interface only have rules
2) The view (web form or window form) can't inherit any more since that's already inherited from window or web form</p>
<p>How can I do that?
Many thanks</p>

363,528 | <p><strong>Question:</strong> How can I process a form using jQuery and the $.ajax request so that the data is passed to a script which writes it to a database?</p>
<p><strong>Problem:</strong>
I have a simple email signup form that when processed, adds the email along with the current date to a table in a MySQL database. Processing the form without jQuery works as intended, adding the email and date. With jQuery, the form submits successfully and returns the success message. However, no data is added to the database.</p>
<p>Any insight would be greatly appreciated! </p>
<pre><code> <!-- PROCESS.PHP -->

$dbpass = '#';
$dbname = '#';
// Open connection to db
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');
mysql_select_db($dbname);
// Form variables
$email = $_POST['email'];
$submitted = $_POST['submitted'];
// Clean up
function cleanData($str) {
$str = trim($str);
$str = strip_tags($str);
$str = strtolower($str);
return $str;

363,565 | <p>I'm looking for any examples anyone might have seen of how to effectively present a list of items (about 1500 in total) so that multiple items can be selected.</p>
<p>I've seen a couple of similar questions where the answer suggests an auto-complete, which works to select a single item, but that doesn't allow users to select multiple items.</p>
<p>Any suggestions, or especially pointers to web apps that might have a potential solution, would be most appreciated!</p>

363,569 | <p>If you use an <code>EnumSet</code> to store conventional binary values (1,2,4 etc), then when there are less than 64 items, I am led to believe that this is stored as a bit vector and is represented efficiently as a long. Is there a simple way to get the value of this long. I want a quick and simple way to store the contents of the set in either a file or database.</p>
<p>If I was doing this the old way, I'd just use a long, and do the bit twidling myself, despite all the issues of typesafety etc.</p>
