188,452 | <p>Is it possible to read and write Word (2003 and 2007) files in PHP without using a COM object?
I know that I can:</p>
<pre><code>$file = fopen('c:\file.doc', 'w+');
fwrite($file, $text);
fclose();
</code></pre>
<p>but Word will read it as an HTML file not a native .doc file.</p>

188,461 | <p>For as long as I can remember I have avoided using switch statement fall-through. Actually, I can't remember it ever entering my consciousness as a possible way to do things as it was drilled into my head early on that it was nothing more than a bug in the switch statement. However, today I ran across some code that uses it by design, which got me immediately wondering what everyone in the community thinks about switch statement fall-through.</p>
<p>Is it something that a programming language should explicitly not allow (like C# does, though it supplies a workaround) or is it a feature of any language that is powerful enough to leave in the programmer's hands?</p>
<p><strong>Edit:</strong>
I wasn't specific enough to what I meant by fall-through. I use this type a lot:</p>
<pre class="lang-js prettyprint-override"><code> switch(m_loadAnimSubCt){
case 0:
case 1:
// Do something
break;
case 2:
case 3:
case 4:
// Do something
break;
}
</code></pre>
<p>However, I'm concerned about something like this.</p>
<pre class="lang-js prettyprint-override"><code> switch(m_loadAnimSubCt){
case 0:
case 1:
// Do something, but fall through to the other cases
// after doing it.
case 2:
case 3:
case 4:
// Do something else.
break;
}
</code></pre>
<p>This way whenever the case is 0, 1 it will do everything in the switch statement. I've seen this by design and I just don't know if I agree that switch statements should be used this way. I think the first code example is very useful and safe. The second seems kind of dangerous.</p>

188,473 | <p>I have a C# object with a critical resource that needs to be flushed very specific points in time making it a bad candidate to leave around for the garbage collector to take care of whenever it gets around to it, how should I handle this? Is there something like C++'s delete operator that will let me manually kill the instance of this object when needed?</p>

188,488 | <p>The problem is following: I want to automate the way my emacs starts.
It has to be split in two buffers and the slime-repl has to be started in the smallest (bottom) buffer. Plus, I want my file to be opened in the bigger (upper) buffer.
In my .emacs there are lines:</p>
<pre><code>(slime)
...
(split-window-vertically -6)
(switch-to-buffer (other-buffer))
(find-file "g:/Private/pa/pa2.lsp")
</code></pre>
<p>SLIME opens o.k. in the bottom buffer, but the file is opened in one of the background buffers, while I want it to be in front.</p>
<p>How to fix this?</p>

188,510 | <p>I have a string "1112224444' it is a telephone number. I want to format as 111-222-4444 before I store it in a file. It is on a datarecord and I would prefer to be able to do this without assigning a new variable.</p>
<p>I was thinking:</p>
<pre><code>String.Format("{0:###-###-####}", i["MyPhone"].ToString() );
</code></pre>
<p>but that does not seem to do the trick.</p>
<p>** UPDATE **</p>
<p>Ok. I went with this solution</p>
<pre><code>Convert.ToInt64(i["Customer Phone"]).ToString("###-###-#### ####")
</code></pre>
<p>Now its gets messed up when the extension is less than 4 digits. It will fill in the numbers from the right. so</p>
<pre><code>1112224444 333 becomes
11-221-244 3334
</code></pre>
<p>Any ideas?</p>

188,639 | <p>I normally don't work on Windows development, and am completely unfamiliar with the toolchain and build system. My embedded product includes some Windows DLLs from a third party in its filesystem (which are used by a Windows machine which mounts the filesystem).</p>
<p>I have a problem: the most recent release of these DLLs have tripled in size compared to previous builds, and they no longer fit in the filesystem. There have not been many changes in the functionality of the DLLs, so I suspect the developers simply forgot to strip debug symbols in this drop. I will ask them, but getting an answer often takes days due to timezone and language differences.</p>
<p>Could someone explain, using simple steps for someone unfamiliar with VisualC, how to determine if a DLL still contains debugging information and how to strip it out?</p>

188,663 | <p>I'm curious as to if there are any best practices relating to JQuery when constructing encapsulated code blocks.</p>
<p>Generally, when I construct a page I like to encapsulate the functions used within that page inside an object. This allows me some encapsulation when building applications. There's nothing I hate more than seeing a JavaScript file with a bunch of this</p>
<pre><code>function doSomethingOnlyRelevantOnThisPage() {
// do some stuff
}
</code></pre>
<p>I this makes for messy design, and doesn't really encapsulate functionality nicely.</p>
<p>Commonly in many frameworks, there is a standard that is used to perform this encapsulation. </p>
<p>In Mootools they favor the Object Literal Notation:</p>
<pre><code>var Site = {
// properties and methods
}
</code></pre>
<p>In YUI they favor the Self Executing Function notation:</p>
<pre><code>(function() { // properties and methods })()
</code></pre>
<p>The nice thing about the second example is that a closure is created, thus allowing you to define private properties and methods.</p>
<p>My question is this: Do any JQuery aficionados have any best practices for creating these cleanly encapsulated structures? What is the rationale behind their use?</p>

188,687 | <p>Is there a way to change the way asp.net generates elements in the WSDL generated from a .asmx file? Specifically, it seems to mark all elements minoccurs="0" and there are some elements that I want to be minoccurs="1" (aka required fields). </p>
<p>One of these is an argument to the web service (e.g. foo(arg1, arg2) where I want arg2 to be generated in the WSDL as minoccurs="1") the other is a particular field in the class that corresponds to arg1. Do I have to forego auto WSDL generation and take a "contract first" approach?</p>

188,692 | <p>I recall reading, on multiple occasions and in multiple locations, that when firing the typical event:</p>
<pre><code>protected virtual OnSomethingHappened()
{
this.SomethingHappened(this, EventArgs.Empty);
}
</code></pre>
<p>e should be EventArgs.Empty if there are no interesting event args, not null.</p>
<p>I've followed the guidance in my code, but I realized that I'm not clear on why that's the preferred technique. Why does the stated contract prefer EventArgs.Empty over null?</p>

188,719 | <p>A friend and I are about to embark on creating a machine that performs some image comparison for sorting. I know about histogram comparison and am generally confident that a small grid of histograms per image precalculated and stored in columns in a database table will generally give us pretty good matches on the first pass because we are matching like things.</p>
<p>The second comparison we want to perform is to use a <a href="http://tinyurl.com/4lo8nl" rel="nofollow noreferrer">color coherence vector</a> (CCV) of images which passed the histogram match test from our subject image to the candidate images. I know that this sort of comparison is more precise.</p>
<p>My friend is confident that he can develop CCV in C# using the <a href="http://www.codeproject.com/KB/cs/Intel_OpenCV.aspx" rel="nofollow noreferrer">C# wrapper</a> to <a href="http://sourceforge.net/projects/opencvlibrary/" rel="nofollow noreferrer">OpenCV</a>. I am pretty sure he can too. However I would like to know:</p>
<ol>
<li>Has anyone already done this in C# and released the source code? Or a C# wrapper?</li>
<li>Are we barking up the wrong tree? (Should we just use CCV and forgo histogram comparisons at the database level? Or is CCV too much?)</li>
</ol>

188,720 | <p>Is there any way in the SQL language or in MySQL (or other DBMA) to transfer a value from one cell to another? For example, say there is a table called user_cars with the following structure:</p>
<pre><code>|id| |user_name| |num_cars|
</code></pre>
<p>Bob has 5 cars, and John has 3 cars. Is there any way to in one query subtract 2 cars from Bob and add 2 to John? I know this can be done with two update queries, but I'd just like to know if there was a more efficient way.</p>

188,769 | <p>I'm trying to show someone a use for interfaces in a crazy situation they've created. They have several unrelated objects in lists, and need to perform an operation on two string properties in each object. I'm pointing out that if they define the properties as part of an interface, they can use the interface object as the type for a method parameter that acts on it; for example:</p>
<pre><code>void PrintProperties(IEnumerable<ISpecialProperties> list)
{
foreach (var item in list)
{
Console.WriteLine("{0} {1}", item.Prop1, item.Prop2);
}
}</code></pre>
<p>This seems like it's all good, but the lists that need to be worked on aren't (and shouldn't) be declared with the interface as the type parameter. However, it doesn't seem like you can cast to a different type parameter. For example, this fails and I can't understand why:</p>
<pre><code>using System;
using System.Collections.Generic;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
List<Test> myList = new List<Test>();
for (int i = 0; i < 5; i++)
{
myList.Add(new Test());
}
PrintList((IEnumerable<IDoSomething>)myList);
}
static void PrintList(IEnumerable<IDoSomething> list)
{
foreach (IDoSomething item in list)
{
item.DoSomething();
}
}
}
interface IDoSomething
{
void DoSomething();
}
public class Test : IDoSomething
{
public void DoSomething()
{
Console.WriteLine("Test did it!");
}
}
}</code></pre>
<p>I <em>can</em> use the <code>Enumerable.Cast<T></code> member to do this, but I was looking for a method that might work in .NET 2.0 as well. It seems like this should be possible; what am I missing? </p>

188,787 | <p>I need to find occurrences of "(+)" in my sql scripts, (i.e., Oracle outer join expressions). Realizing that "+", "(", and ")" are all special regex characters, I tried:</p>
<pre>
grep "\(\+\)" *
</pre>
<p>Now this does return occurrences of "(+)", but other lines as well. (Seemingly anything with open and close parens on the same line.) Recalling that parens are only special for extended grep, I tried:</p>
<pre>
grep "(\+)" *
grep "(\\+)" *
</pre>
<p>Both of these returned only lines that contain "()". So assuming that "+" can't be escaped, I tried an old trick:</p>
<pre>
grep "([+])" *
</pre>
<p>That works. I cross-checked the result with a non-regex tool.</p>
<p><strong>Question</strong>: Can someone explain what exactly is going on with the "+" character? Is there a less kludgy way to match on "(+)"?</p>
<p>(I am using the cygwin grep command.)</p>
<p><strong>EDIT</strong>: Thanks for the solutions. -- And now I see that, per the GNU grep manual that Bruno referenced, "<code>\+</code>" when used in a <em>basic</em> expression gives "+" its <em>extended</em> meaning, and therefore matches one-or-more "("s followed by a ")". And in my files that's always "()".</p>

188,808 | <p>I have a Winform application built with C# and .Net 2.0. I have a textbox set with the MultiLine property.</p>
<p>The problem is when someone writes text with multiple lines (press few enters), presses the save button, and then closes and loads the form again, all the new lines disappear (the text is there at least).</p>
<p>For example, if the textbox had this in it:</p>
<pre><code>Line1
Line3
</code></pre>
<p>It will look like this after I save and load:</p>
<pre><code>Line1 Line3
</code></pre>
<p>Any idea why?</p>
<p><strong>Update</strong></p>
<p>The database is PostGres and when I use PGAdmin I can see all the line AND the "enters". So the persistence seem to have save all the line... the problem seem to be when I put back the string in the Textbox.</p>

188,828 | <p>I've just learned ( yesterday ) to use "exists" instead of "in".</p>
<pre><code> BAD
select * from table where nameid in (
select nameid from othertable where otherdesc = 'SomeDesc' )
GOOD
select * from table t where exists (
select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' )
</code></pre>
<p>And I have some questions about this:</p>
<p>1) The explanation as I understood was: <em>"The reason why this is better is because only the matching values will be returned instead of building a massive list of possible results"</em>. Does that mean that while the first subquery might return 900 results the second will return only 1 ( yes or no )?</p>
<p>2) In the past I have had the RDBMS complainin: "only the first 1000 rows might be retrieved", this second approach would solve that problem?</p>
<p>3) What is the scope of the alias in the second subquery?... does the alias only lives in the parenthesis? </p>
<p>for example </p>
<pre><code> select * from table t where exists (
select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' )
AND
select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeOtherDesc' )
</code></pre>
<p>That is, if I use the same alias ( o for table othertable ) In the second "exist" will it present any problem with the first exists? or are they totally independent?</p>
<p>Is this something Oracle only related or it is valid for most RDBMS?</p>
<p>Thanks a lot</p>

188,834 | <p>I need to dynamically construct an XPath query for an element attribute, where the attribute value is provided by the user. I'm unsure how to go about cleaning or sanitizing this value to prevent the XPath equivalent of a SQL injection attack. For example (in PHP):</p>
<pre><code><?php
function xPathQuery($attr) {
$xml = simplexml_load_file('example.xml');
return $xml->xpath("//myElement[@content='{$attr}']");
}
xPathQuery('This should work fine');
# //myElement[@content='This should work fine']
xPathQuery('As should "this"');
# //myElement[@content='As should "this"']
xPathQuery('This\'ll cause problems');
# //myElement[@content='This'll cause problems']
xPathQuery('\']/../privateElement[@content=\'private data');
# //myElement[@content='']/../privateElement[@content='private data']
</code></pre>
<p>The last one in particular is reminiscent to the SQL injection attacks of yore.</p>
<p>Now, I know for a fact there will be attributes containing single quotes and attributes containing double quotes. Since these are provided as an argument to a function, what would be the ideal way to sanitize the input for these?</p>

188,839 | <p>I use a structure of function pointers to implement an interface for different backends. The signatures are very different, but the return values are almost all void, void * or int.</p>
<pre><code>
struct my_interface {
void (*func_a)(int i);
void *(*func_b)(const char *bla);
...
int (*func_z)(char foo);
};
</code></pre>
<p>But it is not required that a backends supports functions for every interface function. So I have two possibilities, first option is to check before every call if the pointer is unequal NULL. I don't like that very much, because of the readability and because I fear the performance impacts (I haven't measured it, however). The other option is to have a dummy function, for the rare cases an interface function doesn't exist.</p>
<p>Therefore I'd need a dummy function for every signature, I wonder if it is possible to have only one for the different return values. And cast it to the given signature.</p>
<pre><code>
#include <stdio.h>
int nothing(void) {return 0;}
typedef int (*cb_t)(int);
int main(void)
{
cb_t func;
int i;
func = (cb_t) nothing;
i = func(1);
printf("%d\n", i);
return 0;
}
</code></pre>
<p>I tested this code with gcc and it works. But is it sane? Or can it corrupt the stack or can it cause other problems?</p>
<p>EDIT: Thanks to all the answers, I learned now much about calling conventions, after a bit of further reading. And have now a much better understanding of what happens under the hood.</p>

188,850 | <p>I would like a batch file to launch two separate programs then have the command line window close. Actually, to clarify, I am launching Internet Explorer with two different URLs.</p>
<p>So far I have something like this:</p>
<pre><code>start "~\iexplore.exe" "url1"
start "~\iexplore.exe" "url2"
</code></pre>
<p>What I get is one instance of Internet Explorer with only the second URL loaded. Seems the second is replacing the second. I seem to remember a syntax where I would load a new command line window and pass the command to execute on load, but can't find the reference.</p>
<p>As a second part of the question: what is a good reference URL to keep for the times you need to write a quick batch file?</p>
<p>Edit: I have marked an answer, because it does work. I now have two windows open, one for each URL. (thanks!) The funny thing is that without the /d approach using my original syntax I get different results based on whether I have a pre-existing Internet Explorer instance open. </p>
<ul>
<li>If I do I get two new tabs added for
my two URLs (sweet!) </li>
<li>If not I get only one final tab for the second URL I passed in.</li>

188,864 | <p>So C# now allows you to use <code>default(Foo)</code> to get a recognized "not filled in yet"/empty instance of a class -- I'm not sure if it is exactly the same as <code>new Foo()</code> or not. Many library classes also implement a <code>Foo.Empty</code> property, which returns a similar instance. And of course any reference type can point to <code>null</code>. So really, what's the difference? When is one right or wrong? What's more consistent, or performs better? What tests should I use when checking if an object is conceptually "not ready for prime time"? Not everybody has <code>Foo.IsNullOrEmpty()</code>.</p>

188,886 | <p>After my <code>form.Form</code> validates the user input values I pass them to a separate (external) process for further processing. This external process can potentially find further errors in the values.</p>
<p>Is there a way to inject these errors into the already validated form so they can be displayed via the usual form error display methods (or are there better alternative approaches)?</p>
<p>One suggestions was to include the external processing in the form validation, which is not ideal because the external process does a lot more than merely validate.</p>

188,889 | <p>how do I pass additional information to the service method returning the collection of items? I'll attempt to explain what I mean, I have 2 text boxes on a form, I need to fill out names, based of a specific account id in a database. so, I need to pass an integer to the getNamesForDropDown method. I couldn't figure out what to do, so I did the wrong thing, and used the CompletionSetCount to actually pass the information I needed:</p>
<pre><code>[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public string[] getNamesForDropDown(string prefixText, int count)
{
String sql = "Select fldName From idAccountReps Where idAccount = " + count.ToString();
//... rest of the method removed, this should be enough code to understand
//... the evil wrongness I did.
}
</code></pre>
<p>in my front side aspx file, i set the CompletionSetCount based off the Account id the user is currently viewing on that page. </p>
<pre><code><ajaxtk:AutoCompleteExtender
runat="server"
ID="AC1"
TargetControlID="txtAccName"
ServiceMethod="getNamesForDropDown"
ServicePath="AccountInfo.asmx"
MinimumPrefixLength="1"
EnableCaching="true"
CompletionSetCount='<%# Eval("idAccount") %>'
/>
</code></pre>
<p>So, that's definitely a wrong way... what would be the right way?</p>

188,896 | <p>This has been driving me crazy. We have IIS (6) and windows 2008 and ActiveState Perl 5.10. For some reason whenever we do a warn or a carp it eventually corrupts the app pool. Of course, that's a pretty big deal since it means that our errors actually cause problems.</p>
<p>This happened with the previous version of Perl (5.8) and Windows (2003) and IIS (5.) Anyway, basically I put in a <code>carp</code> or a <code>warn</code> and I get an error message and then some garbage text. Any thoughts?</p>

188,940 | <p>I have a project with a formidable data access layer using LinqtoSQL for just about anything touching our databases. I needed to build a helper class that bridges some common crud operations from CLSA objects to LinqToSql ones. Everything has been operating swimmingly until I needed to do a truncate on a table and all I had were “delete” methods.</p>
<p>Uh-oh. A quick search reveals that some people are using YourContext.ExecuteCommand(), which is nice and all, but I am trying to go “t-sql-less” as much as possible these days.</p>
<p>Is there a LINQ way to perform a <a href="http://msdn.microsoft.com/en-us/library/aa260621(SQL.80).aspx" rel="nofollow noreferrer">truncate on a table</a>? Or am I just <a href="http://en.wikipedia.org/wiki/Clueless_(film)" rel="nofollow noreferrer">clueless</a>?</p>

188,942 | <p>I'm writing some cross-platform code between Windows and Mac.</p>
<p>If list::end() "returns an iterator that addresses the location succeeding the last element in a list" and can be checked when traversing a list forward, what is the best way to traverse backwards?</p>
<p>This code workson the Mac but not on Windows (can't decrement beyond first element):</p>
<pre><code>list<DVFGfxObj*>::iterator iter = m_Objs.end();
for (iter--; iter!=m_Objs.end(); iter--)// By accident discovered that the iterator is circular ?
{
}
</code></pre>
<p>this works on Windows:</p>
<pre><code>list<DVFGfxObj*>::iterator iter = m_Objs.end();
do{
iter--;
} while (*iter != *m_Objs.begin());
</code></pre>
<p>Is there another way to traverse backward that could be implemented in a for loop?</p>

188,963 | <p>I find it odd that in Visual C# 2008 Express edition, when you use the database explorer, your options are:</p>
<ol>
<li>Microsoft Access</li>
<li>SQL Server Compact 3.5, and </li>
<li>SQL Server Database File. </li>
</ol>
<p>BUT if you use Visual Web Developer 2008 Express, you can connect to a regular SQL Server, Oracle, ODBC, etc.</p>
<p>For people developing command-line or other C# apps that need to talk to a SQL Server database, do you really need to build your LINQ/Data Access code with one IDE (Visual Web Developer) and your program in another (Visual C#)? </p>
<p>It's not a hard workaround, but it seems weird. If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server, why would they include that feature in one of their free IDEs but not the other? I feel like I might be missing something (like how to do it all in Visual C#).</p>

188,968 | <p>I would like a constraint on a SQL Server 2000 table column that is sort of a combination of a foreign key and a check constraint. The value of my column must exist in the other table, but I am only concerned with values in the other table where one of its columns equal a specified value. The simplified tables are:</p>
<pre>
import_table:
part_number varchar(30)
quantity int
inventory_master:
part_number varchar(30)
type char(1)
</pre>
<p>So I want to ensure the <code>part_number</code> exists in <code>inventory_master</code>, but only if the type is 'C'. Is this possible? Thanks.</p>

189,055 | <p>Typically you will find STL code like this:</p>
<pre><code>for (SomeClass::SomeContainer::iterator Iter = m_SomeMemberContainerVar.begin(); Iter != m_SomeMemberContainerVar.end(); ++Iter)
{
}
</code></pre>
<p>But we actually have the recommendation to write it like this:</p>
<pre><code>SomeClass::SomeContainer::iterator Iter = m_SomeMemberContainerVar.begin();
SomeClass::SomeContainer::iterator IterEnd = m_SomeMemberContainerVar.end();
for (; Iter != IterEnd; ++Iter)
{
}
</code></pre>
<p>If you're worried about scoping, add enclosing braces:</p>
<pre><code>{
SomeClass::SomeContainer::iterator Iter = m_SomeMemberContainerVar.begin();
SomeClass::SomeContainer::iterator IterEnd = m_SomeMemberContainerVar.end();
for (; Iter != IterEnd; ++Iter)
{
}
}
</code></pre>
<p>This is supposed to give a speed and efficiency gain, especially if you are programming consoles, because the .end() function is not called on each iteration of the loop. I just take the performance improvement for granted, it sounds reasonable but i don't know how much and it certainly depends on the type of container and actual STL implementation in use. But having used this style for a couple months now i actually prefer it over the first anyway.</p>
<p>The reason being readability: the for line is neat and tidy. With qualifiers and member variables in real production code it is quite easy to have <strong>really</strong> long for lines if you use the style in the first example. That's why i intentionally made it to have a horizontal scrollbar in this example, just so you see what i'm talking about. ;)</p>
<p>On the other hand, you suddenly introduce the Iter variables to the outer scope of the for loop. But then, at least in the environment i work in, the Iter would have been accessible in the outer scope even in the first example.</p>
<p>What is your take on this? Are there any pro's to the first style other than possibly limiting the scope of Iter?</p>

189,062 | <p>When I navigate on a website utilizing MasterPages, does the application know what page I am on? If so, does it store it in an object I can access?</p>
<p>The reason I am asking is so I can replace this:</p>
<pre><code>//masterpage
<div id="nav_main">
<ul><asp:ContentPlaceHolder ID="navigation" runat="server">
</asp:ContentPlaceHolder></ul>
</div>
//content page(s)
<asp:Content ContentPlaceHolderID="navigation" ID="theNav" runat="server">
<li><a href="default.aspx">Home</a></li>
<li id="current"><a href="faq.aspx">FAQ</a></li>
<li><a href="videos.aspx">Videos</a></li>
<li><a href="#">Button 4</a></li>
<li><a href="#">Button 5</a></li>
</asp:Content>
</code></pre>
<p>With a more elegant solution for the navigation, which highlights the link to the page by having the list item's ID set to "current". Currently each page recreates the navigation with its respective link's ID set to current.</p>

<div id="div2">
More Stuff...

<p>Each of these divs has a drop shadow applied to it via jQuery plugin (jquery.dropshadow.js).</p>

<p>Is there a way that I can update the status of my shadows periodically throughout the course of the animation or can anyone recommend a better drop shadow library that would fix the problem? It doesn't have to be jQuery plugin.</p>

<p>In my case, the #1 desire is for the browser to display an error message. No matter how uninformative.</p>
<p>Closing the ServletResponse outputStream obviously doesn't work. Neither does throwing an exception, even if I don't close first (tested on Tomcat 6.0.16). I think that what I want is either a RST packet, FIN in the middle of a chunk, or badly formed chunk headers.</p>
<p>After that I can worry about how various browsers respond.</p>
<p>Edited for clarification: This is for a file download, perhaps several gigabytes of binary data. I can't make certain that all of the data can be successfully read or decrypted before I have to start sending some of it.</p>

189,156 | <p>Running FxCop on my code, I get this warning:</p>
<blockquote>
<p>Microsoft.Maintainability :
'FooBar.ctor is coupled with 99
different types from 9 different
namespaces. Rewrite or refactor the
method to decrease its class coupling,
or consider moving the method to one
of the other types it is tightly
coupled with. A class coupling above
40 indicates poor maintainability, a
class coupling between 40 and 30
indicates moderate maintainability,
and a class coupling below 30
indicates good maintainability.</p>
</blockquote>
<p>My class is a landing zone for all messages from the server. The server can send us messages of different EventArgs types:</p>
<pre><code>public FooBar()
{
var messageHandlers = new Dictionary<Type, Action<EventArgs>>();
messageHandlers.Add(typeof(YouHaveBeenLoggedOutEventArgs), HandleSignOut);
messageHandlers.Add(typeof(TestConnectionEventArgs), HandleConnectionTest);
// ... etc for 90 other types
}
</code></pre>
<p>The "HandleSignOut" and "HandleConnectionTest" methods have little code in them; they usually pass the work off to a function in another class.</p>
<p>How can I make this class better with lower coupling?</p>

189,228 | <p>When writing async method implementations using the BeginInvoke/EndInvoke pattern the code might look something like the following (and to save you guessing this is an async wrapper around a cache):</p>
<pre><code>IAsyncResult BeginPut(string key, object value)
{
Action<string, object> put = this.cache.Put;
return put.BeginInvoke(key, value, null, null);
}
void EndPut(IAsyncResult asyncResult)
{
var put = (Action<string, object>)((AsyncResult)asyncResult).AsyncDelegate;
put.EndInvoke(asyncResult);
}
</code></pre>
<p>This works perfectly well because it's known what the type of delegate is, so it can be cast. However it starts to get messy when you have two <code>Put</code> methods, because although the method returns void you seemingly have to cast it to a strongly typed delegate to end the invocation, e.g.</p>
<pre><code>IAsyncResult BeginPut(string key, object value)
{
Action<string, object> put = this.cache.Put;
return put.BeginInvoke(key, value, null, null);
}
IAsyncResult BeginPut(string region, string key, object value)
{
Action<string, string, object> put = this.cache.Put;
return put.BeginInvoke(region, key, value, null, null);
}
void EndPut(IAsyncResult asyncResult)
{
var put = ((AsyncResult)asyncResult).AsyncDelegate;
var put1 = put as Action<string, object>;
if (put1 != null)
{
put1.EndInvoke(asyncResult);
return;
}
var put2 = put as Action<string, string, object>;
if (put2 != null)
{
put2.EndInvoke(asyncResult);
return;
}
throw new ArgumentException("Invalid async result", "asyncResult");
}
</code></pre>
<p>I'm hoping there is a cleaner way to do this, because the only thing I care about the delegate is the return type (in this case void) and not the arguments that were supplied to it. But I've racked my brains and asked others in the office, and nobody can think of the answer.</p>
<p>I know one solution is to write a custom <code>IAsyncResult</code>, but that's such a difficult task with the potential threading issues around things like lazy instantiation of the <code>WaitHandle</code> that I'd rather have this slightly hacky looking code than go down that route.</p>
<p>Any ideas on how to end the invocation without a cascading set of <code>is</code> checks?</p>

189,451 | <p>My team is trying to setup an Apache reverse proxy from a customer's site into one of our web applications. </p>
<p><a href="http://www.example.com/app1/some-path" rel="noreferrer">http://www.example.com/app1/some-path</a> maps to <a href="http://internal1.example.com/some-path" rel="noreferrer">http://internal1.example.com/some-path</a> </p>
<p>Inside our application we use struts and have redirect = true set on certain actions in order to provide certain functionality. The 302 status messages from these re-directs cause the user to break out of the proxy resulting in an error page for the end user.</p>
<p>HTTP/1.1 302 Found
Location: <a href="http://internal.example.com/some-path/redirect" rel="noreferrer">http://internal.example.com/some-path/redirect</a></p>
<p>Is there any way to setup the reverse proxy in apache so that the redirects work correctly?</p>
<p><a href="http://www.example.com/app1/some-path/redirect" rel="noreferrer">http://www.example.com/app1/some-path/redirect</a></p>

189,468 | <p>I've had nothing but good luck from SO, so why not try again?</p>
<p>I have an application that needs to show a different image based on the season of the year (spring, summer, winter, fall). I have very specific start and end dates for these seasons.</p>
<p>What I would like from you geniuses is a method called GetSeason that takes a date as input and returns a String value of Spring, Summer, Winter or Fall. Here are the date ranges and their associated seasons:<br></p>
<p>Spring:3/1-4/30<br>
Summer:5/1-8/31<br>
Fall:9/1-10/31<br>
Winter: 11/1-2/28</p>
<p>Can someone provide a working method to return the proper season?
Thanks everyone!</p>

189,493 | <p>Every so often when I'm debugging, I get this message in nice brown text on an ASP.NET error page:</p>
<blockquote>
<p><em>Access to the path
"c:\windows\microsoft.net\framework\(version)\Temporary ASP.NET Files\(blah)"
is denied.</em></p>
</blockquote>
<p>I've never been able to figure out what causes it, what really fixes it, and why it happens.</p>
<p>Often times the path after the "Temporary ASP.NET Files" portion (the "(blah)") does not exist, so I'm not sure why it's looking there.</p>
<p>Sometimes an IISRESET fixes it, and sometimes it doesn't.</p>
<p>Sometimes an aspnet_regiis fixes it, and sometimes it doesn't. </p>
<p>Sometimes a reboot fixes it, and sometimes it doesn't.</p>
<p>For what it's worth I ran into this today with some .NET 1.1 code (yes, still maintaining some - hoping to upgrade it soon) and I'm not sure if I've ever seen it with .NET 2.0 and above. </p>
<p>Does anyone know what causes this and what should fix it? I assume it has multiple possible causes but I'm just curious if someone could shed some light on it.</p>

189,499 | <p>According to the doucmentation for "Directory.Delete( "path", true )", it remove directories, subdirectories, and files in the path.</p>
<p>What does Directory.Delete( "path", false ) do? According to the doucmentation it does "otherwise".</p>
<p>I mean how can you delete a directory without removing the directory, subdirectories, and files?</p>

189,516 | <p>For ActionScript 2, I've used <a href="http://www.naturaldocs.org/" rel="noreferrer">NaturalDocs</a>. However it has pretty poor support for PHP. I've looked so far at <a href="http://www.doxygen.nl/" rel="noreferrer">doxygen</a> and <a href="http://www.phpdoc.org/" rel="noreferrer">phpDocumentor</a>, but their output is pretty ugly in my opinion. Does anyone have any experience with automatic documentation generation for PHP? I'd prefer to be able to use javadoc-style tags, they are short to write and easy to remember.</p>

189,522 | <p>any thoughts on this would be appreciated:</p>
<pre><code>std::string s1 = "hello";
std::string s2 = std::string(s1);
</code></pre>
<p>I'd now expect these two strings to be independent, i.e. I could append ", world" to s2 and s1 would still read "hello". This is what I find on windows and linux but running the code on a HP_UX machine it seems that s2 and s1 are the same string, so modifying s2 changes s1.</p>
<p>Does this sound absolutely crazy, anyone seen anything similar?</p>

189,552 | <p>I'm trying to host a subdomain for my site with a different hosting company and I'm running into issues on how to set it up.</p>
<p>Here are the specifics:</p>
<ul>
<li>Domain is registered with GoDaddy.</li>
<li>Nameservers are pointing to DiscountASP.net where ASP.NET app has been happily running for couple of years.</li>
<li>Would like <code>blog.mydomain.example</code> to point to my account with DreamHost.com to take advantage of their LAMP stack.</li>
</ul>
<p>I have added <code>blog.mydomain.example</code> to DreamHost (after adding <code>mydomain.example</code>) via their control panel. I thought I would be able to add a subdomain entry on GoDaddy to point to DreamHost, but all they allow is <code>blog.mydomain.example</code> = new URL.</p>
<p>In theory I could just take our .biz or .net domain and host it on DreamHost but was hoping I could do it all with a subdomain.</p>
<p>So, to summarize I'd like to know if what I want to do is feasible and if so, how do I go about it (given the constraints of GoDaddy, DiscountASP, & DreamHost).</p>

189,555 | <p>I want to download and parse webpage using python, but to access it I need a couple of cookies set. Therefore I need to login over https to the webpage first. The login moment involves sending two POST params (username, password) to /login.php. During the login request I want to retrieve the cookies from the response header and store them so I can use them in the request to download the webpage /data.php.</p>
<p>How would I do this in python (preferably 2.6)? If possible I only want to use builtin modules.</p>

189,557 | <p>We're running a java/hibernate app going against ORACLE 10g in TESTING. Once in a while, we're seeing this error:</p>
<blockquote>
<p>ORA-00942: table or view does not exist</p>
</blockquote>
<p>Is there a way to find out which table/view(s) ORACLE is talking about ?</p>
<p>I know that I can add extra levels of logging in hibernate which will show all the SQL that it executes on ORACLE and then run that SQL to figure out which TABLE/VIEW is missing or missing permission. But given that it is in TESTING/STAGING, that will slow down performance.</p>
<p>Is there a simple way to narrow down on the Table/View Name ?</p>
<h2>UPDATE :</h2>
<p>Just so you know, I don't have control over the Oracle DB Server Environment. <br>
I enabled Hibernate tracing/logging and found a VALID SQL. I even put Wireshark(which is a TCP packet filter) to see what hibernate actually sends and that was a valid SQL. So, why would Oracle complain about it once in a while and NOT always.</p>
