378,441 | <p>I've an MFC application that currently uses CAtlHttpClient to query a web server for some information.</p>
<p>I'd like to change this so that the query goes over securely, with server authentication, using SSL.</p>
<p>Googling reveals that Microsoft has changed the way they support this several times, e.g., WinInet, WinHTTP, but for the life of me I can't figure out how to do the above using MFC under MSVS 2005.</p>
<p>The application is in C++, and if at all possible, I'd like to avoid dragging .Net into the picture.</p>
<p>Any help, hints, suggestions or pointers gratefully appreciated!</p>
<p>Thanks,</p>
<p>ony</p>

378,449 | <p>I want to use RSpec mocks to provide canned input to a block.</p>
<p>Ruby:</p>
<pre><code>class Parser
attr_accessor :extracted
def parse(fname)
File.open(fname).each do |line|
extracted = line if line =~ /^RCS file: (.*),v$/
end
end
end
</code></pre>
<p>RSpec:</p>
<pre><code>describe Parser
before do
@parser = Parser.new
@lines = mock("lines")
@lines.stub!(:each)
File.stub!(:open).and_return(@lines)
end
it "should extract a filename into extracted" do
linetext = [ "RCS file: hello,v\n", "bla bla bla\n" ]
# HELP ME HERE ...
# the :each should be fed with 'linetext'
@lines.should_receive(:each)
@parser.should_receive('extracted=')
@parser.parse("somefile.txt")
end
end
</code></pre>
<p>It's a way to test that the internals of the block work correctly by passing fixtured data into it. But I can't figure out how to do the actual feeding with RSpec mocking mechanism.</p>
<p><strong>update:</strong> looks like the problem was not with the linetext, but with the:</p>
<pre><code>@parser.should_receive('extracted=')
</code></pre>
<p>it's not the way it's called, replacing it in the ruby code with self.extracted= helps a bit, but feels wrong somehow.</p>

378,465 | <p>I just recently noticed <code>Dictionary.TryGetValue(TKey key, out TValue value)</code> and was curious as to which is the better approach to retrieving a value from the Dictionary.</p>
<p>I've traditionally done:</p>
<pre><code>if (myDict.Contains(someKey))
someVal = myDict[someKey];
...
</code></pre>
<p>unless I know it <em>has</em> to be in there.</p>
<p>Is it better to just do:</p>
<pre><code>if (myDict.TryGetValue(somekey, out someVal)
...
</code></pre>
<p>Which is the better practice? Is one faster than the other? I would imagine that the Try version would be slower as its 'swallowing' a try/catch inside itself and using that as logic, no?</p>

378,490 | <p>I'm running on win2003 server, PHP 526, via the cmd-line.</p>
<p>I have a cmdline string:</p>

<p>Trying to do this in php code</p>
<pre><code>$out = `$cmd`; # note use of backticks AKA shell_exec

378,493 | <p>I wanted to create my own Python exception class, like this:</p>
<pre><code>class MyException(BaseException):
def __init__(self, errno, address):
if errno == 10048:
mess = str(address) + ' is already in use'
else:
mess = 'Unable to open ' + str(address)
BaseException.__init__(mess)
</code></pre>
<p>but when the program got to the call to <code>BaseException.__init__()</code>, I got this traceback:</p>
<pre><code>BaseException.__init__(mess)
TypeError: descriptor '__init__' requires a 'exceptions.BaseException' object but received a 'str'
</code></pre>
<p>I thought that BaseException would take any set of arguments. Also, how I am supposed to pass an 'exceptions.BaseException' object into exceptions.BaseException's constructor?</p>

378,515 | <p>I've noticed that boost.asio has a lot of examples involving sockets, serial ports, and all sorts of non-file examples. Google hasn't really turned up a lot for me that mentions if asio is a good or valid approach for doing asynchronous file i/o.</p>
<p>I've got gobs of data i'd like to write to disk asynchronously. This can be done with native overlapped io in Windows (my platform), but I'd prefer to have a platform independent solution.</p>

<li>boost.asio has any kind of file support</li>

378,524 | <p>I'm trying to create a Regex usuable in C# that will allow me to take a list of single letters and/or letter groups and ensure that a word is only comprised of items from that list. For instance:</p>
<ul>
<li>'a' would match 'a', 'aa', 'aaa', but not 'ab'</li>
<li>'a b' would match 'a', 'ab', 'abba', 'b', but not 'abc'</li>
<li>'a b abc' would match 'a', 'ab', 'abc', 'aabc', 'baabc', but not 'ababac'</li>
</ul>
<p>I thought something of the form</p>
<pre><code>(a|b|abc)*
</code></pre>
<p>would work, but it incorrectly matches the last term. Here's the code I'm testing with:</p>
<pre><code>[Fact]
public void TestRegex()
{
Regex regex = new Regex("(a|b|abc)*");
regex.IsMatch("a").ShouldBeTrue();
regex.IsMatch("b").ShouldBeTrue();
regex.IsMatch("abc").ShouldBeTrue();
regex.IsMatch("aabc").ShouldBeTrue();
regex.IsMatch("baabc").ShouldBeTrue();
// This should not match ... I don't think anyway
regex.IsMatch("ababac").ShouldBeFalse();
}
</code></pre>
<p>I have a pretty basic understanding of regex, so apologies if I'm missing something obvious here :)</p>
<p><strong>Update</strong>
<em>I don't understand why your counter-example is a counter-example : ababac = a b a bac. cCould you clarify ?</em></p>
<p>I only want to use 'a', 'b', and 'abc' - 'bac' would be a completely different term.</p>
<p>Let me give another example: Using 'ba' and 't', I could match the word 'bat', but not 'tab'. The order of the letters inside the letter groups is important.</p>
<p>(Tests with Diadistis' solution)</p>
<pre><code> [Fact]
public void TestRegex()
{
Regex regex = new Regex(@"\A(?:(e|l|ho)*)\Z");
regex.IsMatch("e").ShouldBeTrue();
regex.IsMatch("l").ShouldBeTrue();
regex.IsMatch("ho").ShouldBeTrue();
regex.IsMatch("elho").ShouldBeTrue();
regex.IsMatch("hole").ShouldBeTrue();
regex.IsMatch("holle").ShouldBeTrue();
regex.IsMatch("hello").ShouldBeFalse();
regex.IsMatch("hotel").ShouldBeFalse();

378,548 | <p>How can you join between a table with a sparse number of dates and another table with an exhaustive number of dates such that the gaps between the sparse dates take the values of the previous sparse date?</p>
<p>Illustrative example:</p>
<pre><code>PRICE table (sparse dates):
date itemid price
2008-12-04 1 $1
2008-12-11 1 $3
2008-12-15 1 $7
VOLUME table (exhaustive dates):
date itemid volume_amt
2008-12-04 1 12345
2008-12-05 1 23456
2008-12-08 1 34567
2008-12-09 1 ...
2008-12-10 1
2008-12-11 1
2008-12-12 1
2008-12-15 1
2008-12-16 1
2008-12-17 1
2008-12-18 1
</code></pre>
<p>Desired result:</p>
<pre><code>date price volume_amt
2008-12-04 $1 12345
2008-12-05 $1 23456
2008-12-08 $1 34567
2008-12-09 $1 ...
2008-12-10 $1
2008-12-11 $3
2008-12-12 $3
2008-12-15 $7
2008-12-16 $7
2008-12-17 $7
2008-12-18 $7
</code></pre>
<p>Update:</p>
<p>A couple people have suggested a correlated subquery that accomplishes the desired result. (Correlated subquery = a subquery that contains a reference to the outer query.)</p>
<p>This will work; however, I should have noted that the platform I'm using is MySQL, for which correlated subqueries are poorly optimized. Any way to do it without using a correlated subquery?</p>

378,555 | <p>when I press the Maximize button on my WPF app, all the controls therein expand perfectly horizontally, but they do not expand to fill the window vertically. I figure it Maximize handles it horizontally, it should handle it vertically as well. Should I be setting a property somewhere on each control?

378,559 | <p>I restored my development database from production, and the stored procedures I need in my development environment doesn't exist in my production database. Is there a command Ii can use to import the developmetn stored procedures back into SQL Server. There are about 88 files, as each procedure is in a different text file.</p>
<p>TIA!

378,564 | <p>Are there any sorts of useful idioms I can make use of when writing an API that is asynchronous? I would like to standardize on something as I seem to be using a few different styles throughout. It seems hard to make asynchronous code simple; I suppose this is because asynchronous operations are anything but.</p>
<p>At the most basic level, the user of the API must be able to:</p>
<ol>
<li>Have data pushed to them as it becomes available
<li>Check the status of the asynchronous operation
<li>Be notified of errors that occur
<li>Wait for completion (converting the asynchronous operation to a synchronous one)
</ol>
<p>My classes support several asynchronous operations. I have been putting some of the status/error callbacks in the class around it, but the class is becoming gunked up with a lot of incidental fields, as well as getting too large. I am curious if anyone has used an asynchronous API they found to be well-organized. I have looked at .NET's Begin/EndAsyncOperation + AsyncResult design, as well as some classes in Java (e.g. Future).</p>
<p>This is being written in Python, so it remains very flexible. There is a caveat: some of these asynchronous operations are being marshaled to a remote machine and executed over there. Thus, not every operation necessarily executes in a separate thread.</p>

378,596 | <p>I wrote a google map lookup page. Everthing worked fine until I referenced the page to use a master page. I removed the form tag from the master page as the search button on the map page is a submit button. Everything else on my page appears but the google map div appears with map navigation controls and logo but no map visuals appear.</p>
<p>I retested with the previous, non master page version and the map appears correctly. Any thoughts on what I'm missing?</p>

378,608 | <p>I have a set of data that models a hierarchy of categories. A root category contains a set of top-level categories. Each top-level category contains a set of sub-categories.</p>
<p>Each sub category has a set of organizations. A given organization can appear in multiple sub categories. </p>
<p>The leaf nodes of this hierarchy are organizations. An organization can potentially appear in multiple sub-categories.</p>
<p>The data is stored in three SQL tables:</p>
<pre><code>organizations
organization_id organization_name
1 Org A
2 Org B
3 Org C
4 Org D
5 Org E
6 Org F
categories
category_id parent_id category_name
0 NULL Top Level Category
1 0 First Category
2 0 Second Category
3 1 Sub Category A
4 1 Sub Category B
5 1 Sub Category C
6 2 Sub Category D
organizations_categories -- Maps organizations to sub_categories
organization_id category_id
1 3
2 3
2 6
3 4
4 4
5 4
6 5
6 4
7 6
8 6
</code></pre>
<p>I would like to be able to select a list of all unique organizations under a given category or sub-category. </p>
<p>The way I'm doing it right now involves first figuring out which sub categories have been requested and then looping through each sub_category in code and performing a select to get all organizations mapped to that category. The results of each select are appended to an array. This array contains duplicates whenever an organization appears in multiple sub categories.</p>
<p>I would love to replace this kludge with a query that can efficiently select a list of distinct organizations given an id of one of the categories in the hierarchy.</p>
<p>I am devloping this solution using PHP and MySQL.</p>
<p>Thanks for your time and suggestions.</p>

378,630 | <p>I am writing a DLL with mixed C/C++ code. I want to specify the ordinals of the functions I'm exporting. So I created a .DEF file that looks like this</p>
<pre><code>LIBRARY LEONMATH
EXPORTS
sca_alloc @1
vec_alloc @2
mat_alloc @3
sca_free @4
vec_free @5
mat_free @6
...
</code></pre>
<p>I would like to specify the ordinals of my C++ functions and class methods too. I have tried using the Dependency Walker to add the mangled names of my functions to the .DEF file:</p>
<pre><code> ??0CScalar@@QAE@XZ @25
??0CScalar@@QAE@O@Z @26
??0CScalar@@QAE@ABV0@@Z @27
??1CScalar@@QAE@XZ @28
</code></pre>
<p>But this has failed. Any ideas why this could be happening?</p>
<hr>
<p><b>EDIT:</b> kauppi made a good observation, so I'm adding more information to the question.</p>
<ul>
<li><b>Platform:</b> Windows (and I'm not interested in portability)</li>
<li><b>Compiler:</b> Microsoft's C++ compiler (I'm using VS2005)</li>
<li><b>Why I want to do this?:</b> Using the ordinals has the advantage of letting me call exported C++ functions from C code.</li>

378,632 | <p>I have the following html in my webpage (simplified).</p>
<pre><code><button type="submit" name="action" value="ButtonA">Click Here</button>
</code></pre>
<p>In Firefox, it submits "ButtonA" as the value for the "action" form value. However, in IE7, it submits "Click Here". Is there any way to resolve this? I don't want to use input tags, because I need to be able to customize the text without affecting the values sent back to the form (localization). Basically, I want to be able to have multiple buttons with the same name, and depending on their value, do a different action when submitted. Is there any easy with to get IE to act correctly in this case?</p>
<p>[MORE]</p>
<p>Maybe I should be more clear, but I can't use</p>
<pre><code><input type="submit" name="Action" value="ButtonA">
</code></pre>
<p>because I need to be able to change the text displayed for localization rules, without affecting the actual value of the button that's submitted with the form.</p>
<p>[MORE]</p>
<p>To elaborate even more, Basically, I want the button to be able to say "Save" or "Sauver" depending on the language, but not have the value submitted to the server change. I also want to have multiple buttons with the same name, and depending on the value, do something, rather than depending on the button name, and testing if there is a value for that button. The code is already written from that perspective, and I just want to be able to change the displayed text in the values, without existing server side processing code.</p>
<p>Here is a link with a very good <a href="http://allinthehead.com/retro/330/coping-with-internet-explorers-mishandling-of-buttons" rel="noreferrer">explanation of the problem</a>, with some possible work arounds.</p>

<p>I understand that using "is" causes a cast to be made and then when i want to do something with it, cast it a second time. Is there a more efficient way to check the type? I made a console app trying "if(body2.Tag.GetType() == typeOf(Dog))" but it appears to be even slower than using "is".</p>

378,678 | <p>Throughout the history of software development, it sometimes happens that some person (usually unknown, probably unwittingly) made what, at the time, seemed a trivial, short-term decision that changed the world of programming. What events of this nature come to mind, and what have been our industry's response to mitigate the pain?</p>
<p>Illustration (the biggest one I can think of): When IBM designed the original PC, and decided to save a couple dollars in manufacturing costs by choosing the half-brain-dead 8088 with 8-bit-addressable memory, instead of one of the 16-bit options (8086, 680n, etc.), dooming us to 20 years of address offset calculations.</p>
<p>(In response, a lot of careers in unix platform development were begun.)</p>
<p>Somewhere toward the other end of the scale lies the decision someone made to have a monster Shift Lock key at the left end of the keyboard, instead of a Ctrl key.</p>

378,704 | <p>It sounds wonky, but this is what I'm trying to do with javascript (this is all triggered by an event handler):</p>
<ol>
<li>Save the contents of a page (preferably the whole document or at least documentElement object) into a variable.</li>
<li>Create an iframe and insert it into
the body.</li>
<li>Replace the document of the iframe with the saved document (so that the iframe now has the same content as the outer page).</li>
<li>Change the outer page.</li>
</ol>
<p>Everything is dandy except the part about replacing the iframe's document. I've tried a bunch of different things, but all have problems (they are outlined below). I need event handlers, styles, links, etc to all work correctly when the page is in the iframe.</p>
<p>And yes, I realize that I could just set the src of the iframe to the url of the current page, but I'd rather the page not have to load. If I can't come up with a solution, this is what I'll do.</p>
<hr>
<h3>Things that I've already tried:</h3>
<pre><code>var html = iframe.contentWindow.document.importNode(document.documentElement, true);
iframe.contentWindow.documentElement = html;
</code></pre>
<p>I get an error message ("setting a property that only has a getter").</p>
<pre><code>var html = iframe.contentWindow.document.importNode(document.documentElement, true);
var idoc = iframe.contentWindow.document;
while(idoc.firstChild) idoc.removeChild(idoc.firstChild); // remove all children (firefox automatically creates an html element for iframes with no src)
idoc.appendChild(html); // insert a new documentElement
</code></pre>
<p>This seems to work, but doesn't re-render the styles, and event handlers don't work. Interestingly, links don't work either, and they aren't even styled with the browser's default styles. Maybe this is because the DOCTYPE isn't copied to the iframe?</p>
<pre><code>iframe.contentWindow.document.documentElement.innerHTML = document.documentElement.innerHTML;
</code></pre>
<p>This has the same behavior as the removeChild/appendChild method.</p>
<hr>
<p>It seems like if I could just get the browser to re-render the styles and re-register the event handlers then I'd be golden, but I'm not sure if this is even possible.</p>

378,752 | <p>Is there any way to map to a network drive by using a stored procedure? I have tried: </p>
<pre><code>xp_cmdshell 'net use Q: [shared_network_drive] [pwd] /user:[username]'
</code></pre>
<p>but I got an error saying something like </p>
<pre><code>'System error 1312 has occurred.'
'A specified logon session does not exist. It may already have been terminated.'
</code></pre>
<p>However, when I run the same command in a cmd console in the same box as the SQL server machine, there is no problem at all. It looks like that SQL process does pass correct logon credential information. Any way to do it by SQL SP?</p>

<p>The logs just end after the user clicks the button so i'm thinking there may be some exception/error that we are not logging. Maybe an OutOfMemoryError.</p>
<p>Any suggestions on how to proceed? to get more information. Java command setting etc.</p>

378,768 | <p>This morning, I tried to commit a revision to Subversion and found that all of a sudden I did not have permission to do so.</p>
<pre>Can't move '/svn/db/txn-protorevs/21000-ga9.rev' to '/svn/db/revs/21/21001':
Permission Denied</pre>
<p>Looking at the revs directory, I noticed that somebody had committed the 21000th revision, and the group write permission for the new directory is missing for some reason.</p>
<pre>
drwxrwsr-x 2 svn svn 24K 2008-10-27 10:04 19
drwxrwsr-x 2 svn svn 24K 2008-12-18 07:13 20
drwxr-sr-x 2 jeff svn 4.0K 2008-12-18 11:18 21
</pre>
<p>Setting the group write permission on that directory allows me to commit, so I'm good for another 1000 revisions. But why does this happen, and what can I change to make sure it doesn't happen again?</p>

378,786 | <p>When writing an abstract class, or a class that doesn't get instantiated directly... do you tend to write a dealloc method in the abstract class and release where appropriate, and then allow for children to call [super dealloc] and then worry about only instance variables they add which aren't part of the super class?</p>
<p>How do you folks manage memory with abstract classes?</p>
<p>I'm thinking something along the lines of:</p>
<pre><code>@interface ClassA : NSObject {
NSArray *foo;
}
@end
@implementation ClassA
- (void) dealloc {
[foo release];
[super dealloc];
}
@end
@interface ClassB : ClassA {
NSArray *bar;
}
@end
@implementation ClassB
- (void) dealloc {
[bar release];
[super dealloc];
}
@end
</code></pre>
<p>Please pardon any syntactical errors, I just wrote this up on the fly. Does the above make sense or should memory be managed differently? GC isn't an option as I'm doing this on the iPhone.</p>

<pre><code>Public Class MyEnumClass(of T)
Public MyValue as T

<p>This is vast oversimplification of the actual class, but basically I know that T is an enumeration (if it is not then there will be many other problems, and is a logical error made by the programmer)</p>
<p>Basically I want to get the underlying integer value of MyValue.</p>

378,811 | <p>I'm trying to get Python scripts, called from a web browser, to work. I keep getting the error: </p>
<pre><code>500 Internal Server Error
</code></pre>
<p>When I check my error logs I see the message </p>
<pre><code>Premature end of script headers
</code></pre>
<p>The only documentation of this error online says that it can be the result of having improper line return characters in your script, but I wrote my test script right from the shell with pico. Also, when I run the file from the command line it executes just fine.
"
So far the only change I have made to apache is to add the .py to the "AddHandler cgi-script" line.</p>
<p>Thanks!</p>
<hr>
<p>Thanks for the quick responses. Here is the latest version of the test code. I added a couple new lines before the output as suggested but still get the same error:</p>
<pre><code>#!/usr/local/bin/python
print "Content-type: text/html\n"
print "\n\n"
print "<HTML>"
print "<HEAD>"
print "<TITLE>Test</TITLE>"
print "</HEAD>"
print "<BODY>"
print "<H2>Hi there.</h2>"
print "</BODY>"
print "</HTML>"
</code></pre>
<p>Some other details: I am running Apache 1.3 and don't have mod_python. I set apache to recognize .py as mentioned above. I am running the script from the main public_html folder. </p>
<hr>
<p>An update. It doesn't seem to matter what I put in the shebang line. I tried all of the suggestions and even if I leave it blank the same error is showing up in the errors log and I'm getting a 500 error. </p>
<p>I'm running Apache/1.3.41 on linux (red hat 3.4) with WHM/Cpanel installed. </p>

378,847 | <p><code>CGI.escapeHTML</code> is pretty bad, but <code>CGI.unescapeHTML</code> is completely borked. For example:</p>
<pre><code>require 'cgi'
CGI.unescapeHTML('&#8230;')
# => "…" # correct - an ellipsis
CGI.unescapeHTML('&hellip;')
# => "&hellip;" # should be "…"
CGI.unescapeHTML('&#162;')
# => "\242" # correct - a cent
CGI.unescapeHTML('&cent;')
# => "&cent;" # should be "\242"
CGI.escapeHTML("…")
# => "…" # should be "&#8230;"
</code></pre>
<p>It appears that <code>unescapeHTML</code> knows about all of the numeric codes plus <code>&amp;</code>, <code>&lt;</code>, <code>&gt;</code>, and <code>&quot;</code>. And <code>escapeHTML</code> only knows about those last four -- it doesn't do any of the numeric codes. I understand that escaping doesn't generally need to be as robust since HTML will allow the literal versions of most characters except the four that <code>CGI.escapeHTML</code> knows about. But unescaping should really be better.</p>
<p>Is there a better tool out there, at least for unescaping?</p>

378,848 | <p>I'm wanting to capture my search terms and pass them to a JavaScript variable, but I don't know how to handle quotes that might come through.</p>
<p>Here's what I have currently:</p>
<pre><code>var searchTerms = "<!--#echo var="terms"-->";
var pattern = / /g;
newSearchTerms = searchTerms.replace(/[^a-zA-Z 0-9]+/g,'');
var searchStr=newSearchTerms.replace(pattern,"_");

<p>How do I escape the string before it gets into script?</p>

378,876 | <p>Consider the following example. It consists of two header files, declaring two different namespaces:</p>
<pre><code>// a1.h
#pragma once
#include "a2.h"
namespace a1

const int x = 10;
typedef a2::C B;
}
</code></pre>
<p>and the second one is</p>
<pre><code>// a2.h
#pragma once
#include "a1.h"
namespace a2 {
class C {
public:
int say() {
return a1::x;
}
};
}
</code></pre>
<p>And a single source file, <code>main.cpp</code>:</p>
<pre><code>#include <iostream>
#include "a1.h"
#include "a2.h"
int main()
{
a2::C c;
std::cout << c.say() << std::endl;
}
</code></pre>
<p>This way it doesn't compile (tried GCC and MSVC). The error is that <code>a1</code> namespaces is not declared (C2653 on Windows). If you change include order in <code>main.cpp</code> this way:</p>
<pre><code>#include "a2.h"
#include "a1.h"
</code></pre>
<p>you get a symmetric error message, i.e. <code>a2</code> namespace is not declared.</p>

'foo bar baz'[0, 4.5en]

378,895 | <p>I'm having a little bit of trouble understanding what the problem is here. I have a bit of code that pulls records from a database using LINQ and puts them into an object which is cast into an interface. It looks a bit like this:</p>
<pre><code>public IEnumerable<ISomeObject> query()
{
return from a in dc.SomeTable
select new SomeObject
{
//Assign various members here
} as ISomeObject;
}
</code></pre>
<p>When I test this, I put the returned IEnumerable into a variable called results and run this line:</p>
<pre><code>Assert.AreEqual(EXPECTED_COUNT, results.Count());
</code></pre>
<p>When this is run, I get a System.Security.VerificationException: "Operation could destabilize the runtime."</p>
<p>I found the solution <a href="http://devlicio.us/blogs/derik_whittaker/archive/2008/11/29/quot-operation-could-destabilize-the-runtime-quot-from-casting-from-concrete-to-interfaces-with-linq.aspx" rel="noreferrer">here</a>, which is this:</p>
<pre><code>var results = from a in dc.SomeTable
select new SomeObject
{
//Assign various members here
} as ISomeTable;
return results.OfType<ISomeObject>();
</code></pre>
<p>This works, but I'm having trouble understanding what's happening here. Why did I get the exception in the first place and how did the lines of code above fix it? The MSDN documentation seems to suggest that this is an issue of type safety, but I'm not seeing where the previous code was type-unsafe.</p>
<p><strong>UPDATE</strong>
A little bit more information I found out. The first example works if I make the return type IQueryable. This sheds a little bit more light on <em>what</em> was going wrong, but I'm still confused about the <em>why</em>. Why didn't the compiler force me to cast the IEnumerable into an IQueryable?</p>

378,927 | <p>I need to know if a variable in Python is a string or a dict. Is there anything wrong with the following code?</p>
<pre><code>if type(x) == type(str()):
do_something_with_a_string(x)
elif type(x) == type(dict()):
do_somethting_with_a_dict(x)
else:
raise ValueError
</code></pre>
<p><strong>Update</strong>: I accepted avisser's answer (though I will change my mind if someone explains why <code>isinstance</code> is preferred over <code>type(x) is</code>).</p>
<p>But thanks to nakedfanatic for reminding me that it's often cleaner to use a dict (as a case statement) than an if/elif/else series.</p>
<p>Let me elaborate on my use case. If a variable is a string, I need to put it in a list. If it's a dict, I need a list of the unique values. Here's what I came up with:</p>
<pre><code>def value_list(x):
cases = {str: lambda t: [t],
dict: lambda t: list(set(t.values()))}
try:
return cases[type(x)](x)
except KeyError:
return None
</code></pre>
<p>If <code>isinstance</code> is preferred, how would you write this <code>value_list()</code> function?</p>

<p>My guess is no, because Server.Transfer() copies HttpContext.Items, among other things. To copy this data between AppDomains, would cause threading and memory sharing concerns a in a world were thread isolation is strictly enforced. </p>

378,958 | <p>There is someone in my team that swears by using some kind of GVim feature to do manually code folding.</p>
<p>As I'm using another editor and do not really need the folding feature, I think it only pollutes the source code with tags like:</p>
<pre><code>/* {{{1 */
</code></pre>
<p>Convincing the person not to use this folding is not an option (got into some heated discussions before).</p>
<p>I'm not really a GVim guy, I'm wondering if there are not any other ways to do the folding without changing the team's code? </p>
<ul>
<li>Maybe putting the folding directions in a separate file, or </li>
<li>Doing some kind of smart folding that takes the syntax of the programming language into account without changing the source code?</li>

378,983 | <p>I'm using IPAddress.TryParse() to parse IP addresses. However, it's a little too permissive (parsing "1" returns 0.0.0.1). I'd like to limit the input to dotted octet notation. What's the best way to do this?</p>
<p>(Note: I'm using .NET 2.0)</p>
<hr>
<p><strong>Edit</strong></p>
<p>Let me clarify:</p>
<p>I'm writing an app that will scan a range of IPs looking for certain devices (basically a port scanner). When the user enters "192.168.0.1" for the starting address, I want to automatically fill in "192.168.0.255" as the ending address. The problem is that when they type "1", it parses as "0.0.0.1" and the ending address fills in as "0.0.0.255" - which looks goofy.</p>

AS
BEGIN

Usage:

<p>The same SP with a local that is hardcoded.</p>

DECLARE @DATA_DT_ID AS int
SET @DATA_DT_ID = 20081130
-- Stuff here that depends on DATA_DT_ID
END
</code></pre>
<p>You can see where I put in the (redundant, even) <code>WITH RECOMPILE</code> options in order to avoid parameter sniffing (this was never necessary in development where this thing worked fine)</p>
<p>The one that works completes fine in a minute or two, the other never completes - just sits there for hours.</p>
<p>This problem never happened on the development server (build 9.00.3282.00), the production server is build 9.00.3068.00</p>
<p>I've removed all kinds of code from the procs to try to get down to the minimal version which still exhibits the problem, and have been very careful to keep both versions of the SP the same except for that one parameter.</p>
<p>I have plenty of other SPs which take parameters and they do run fine. I've also <code>DROP</code>ped and re<code>CREATE</code>ed the SPs.</p>
<p>Any ideas?</p>
<p>And yes, I have a DBA looking at it and I do not have SHOWPLAN or any useful rights on production to see if there is blocking (in case one's plan results in a lock escalation I guess - again, the only difference is the parameter)</p>
<p>I've reviewed all the SQL Server build information and don't see a known issue about this, so until I figure it out or the DBA figures it out, I'm kind of stuck.</p>
<p><strong>UPDATE</strong></p>
<p>This also fails to complete (this is actually the normal form for these SPs - I just put a default in to make it easier to switch back and forth during testing)</p>
<pre><code>ALTER PROCEDURE [usp_debug_fails]
@DATA_DT_ID AS int
WITH RECOMPILE
AS
BEGIN
/*
Usage:
EXEC [usp_debug_fails] 20081130 WITH RECOMPILE

-- Stuff here that depends on DATA_DT_ID
END
</code></pre>
<p>however this one completes (which may work as a workaround, although I have about 25 of these SPs to modify which all have the same form):</p>
<pre><code>ALTER PROCEDURE [usp_debug_fails]
@DATA_DT_ID_in AS int

379,053 | <p>I know that having diamond inheritance is considered bad practice. However, I have 2 cases in which I feel that diamond inheritance could fit very nicely. I want to ask, would you recommend me to use diamond inheritance in these cases, or is there another design that could be better.</p>
<p><strong>Case 1:</strong> I want to create classes that represent different kinds of "Actions" in my system. The actions are classified by several parameters: </p>
<ul>
<li>The action can be "Read" or "Write".</li>
<li>The action can be with delay or without delay (It is not just 1 parameter. It changes the behavior significantly).</li>
<li>The action's "flow type" can be FlowA or FlowB.</li>
</ul>
<p>I intend to have the following design:</p>
<pre><code>// abstract classes
class Action
{
// methods relevant for all actions
};
class ActionRead : public virtual Action
{
// methods related to reading
};
class ActionWrite : public virtual Action
{
// methods related to writing
};
class ActionWithDelay : public virtual Action
{
// methods related to delay definition and handling
};
class ActionNoDelay : public virtual Action {/*...*/};
class ActionFlowA : public virtual Action {/*...*/};
class ActionFlowB : public virtual Action {/*...*/};
// concrete classes
class ActionFlowAReadWithDelay : public ActionFlowA, public ActionRead, public ActionWithDelay
{
// implementation of the full flow of a read command with delay that does Flow A.
};
class ActionFlowBReadWithDelay : public ActionFlowB, public ActionRead, public ActionWithDelay {/*...*/};
//...
</code></pre>
<p>Of course, I will obey that no 2 actions (inheriting from Action class) will implement the same method.</p>
<p><strong>Case 2:</strong> I implement the composite design pattern for a "Command" in my system. A command can be read, written, deleted, etc. I also want to have a sequence of commands, which can also be read, written, deleted, etc. A sequence of commands can contain other sequences of commands. </p>
<p>So I have the following design:</p>
<pre><code>class CommandAbstraction
{
CommandAbstraction(){};
~CommandAbstraction()=0;
void Read()=0;
void Write()=0;
void Restore()=0;
bool IsWritten() {/*implemented*/};
// and other implemented functions
};
class OneCommand : public virtual CommandAbstraction
{
// implement Read, Write, Restore
};
class CompositeCommand : public virtual CommandAbstraction
{
// implement Read, Write, Restore
};
</code></pre>
<p>In addition, I have a special kind of commands, "Modern" commands. Both one command and composite command can be modern. Being "Modern" adds a certain list of properties to one command and composite command (mostly same properties for both of them). I want to be able to hold a pointer to CommandAbstraction, and initialize it (via new) according to the needed type of command. So I want to do the following design (in addition to the above) :</p>
<pre><code>class ModernCommand : public virtual CommandAbstraction
{
~ModernCommand()=0;
void SetModernPropertyA(){/*...*/}
void ExecModernSomething(){/*...*/}
void ModernSomethingElse()=0;
};
class OneModernCommand : public OneCommand, public ModernCommand
{
void ModernSomethingElse() {/*...*/};
// ... few methods specific for OneModernCommand
};
class CompositeModernCommand : public CompositeCommand, public ModernCommand
{
void ModernSomethingElse() {/*...*/};
// ... few methods specific for CompositeModernCommand
};
</code></pre>
<p>Again, I will make sure that no 2 classes inheriting from CommandAbstraction class will implement the same method.</p>
<p>Thank you.</p>

379,062 | <p>Does anyone have a method to understand complex SQL statements? When reading structural / OO code there are usually layers of abstraction that help you break it down into manageable chunks. Often in SQL, though, it seems that you have to keep track of what's going on in multiple parts of a query all at the same time.</p>
<p>The impetus for this question is the SQL query discussed in <a href="https://stackoverflow.com/questions/378548/need-help-with-a-complex-join-statement-in-sql">this question about a complex join</a>. After staring at the answer queries for a number of minutes I finally decided to step through the query using particular records to see what was going on. That was the only way I could think of to understand the query piece by piece.</p>
<p>Is there a better way to break a SQL query down into manageable pieces?</p>

379,128 | <p>How would someone who really knows how to take advantage of dynamic programming languages approach programming differently than someone working in a static language? </p>
<p>I'm familiar with the whole debate over static versus dynamic typing, but that's not what I'm getting at. I'd like to discuss problem solving techniques that are practical in dynamic languages but not in static languages. </p>
<p>Most of the code I've seen written in dynamic programming languages isn't very different than code written in static programming languages. As the saying goes, you can write FORTRAN in any language, and many people do. But some people use dynamic programming languages to solve problems in a way that wouldn't easily translate into, for example, C++. What are some of their techniques?</p>
<p>What are some good resources that discuss how to use dynamic programming languages? Not books on language syntax or API reference, but resources on problem solving approaches that take advantage of dynamic language capabilities.</p>
<p>EDIT (1/5/2009): I appreciate the answers below, but they don't seem to account for the huge increases in productivity that dynamic language advocates say they experience. </p>

379,131 | <p><strong>Area :</strong>
Textbox in Silverlight</p>
<p><strong>Question:</strong>
I need to know what "line number" that is currently edited.</p>
<p><strong>I've tried:</strong>
As a workaround I've tried splitting with textBox.Split("\r") and counting matches on Regex with similar performance. Performance during the first 2000 lines are acceptable but then it gets to slow.</p>
<p><strong>Why:</strong>
I have a Textbox and a Listbox side-by-side. The item index in the listbox corresponds to line number in the textbox and the content (of the ListboxItem) is a "processed" version of the corresponding line in textbox.</p>
<p><strong>Alternative:</strong>
A more performance friendly strategy than my hacks. </p>

379,133 | <p>I had a straight forward approach of turning Key/Value pairs of an XML excerpt into an NSDictionary when I started a simple iPhone application. The problem is, I need to turn those NSDictionary's instances that once populated my UITableView's into custom classes because they require behavior and additional complexity. The problem here is that now in order for me to instantiate an object and fill its instance variables with key/value pairs from a web service becomes that much more difficult. I can no longer throw it into a method that iterates through the XML and uses KVC to set its instance variables. </p>
<p>What kind of other solution is out there?</p>

379,172 | <p>Currently I am working on a project where goto statements are heavely used. The main purpose of goto statements is to have one cleanup section in a routine rather than multiple return statements.
Like below:</p>
<pre><code>BOOL foo()
{
BOOL bRetVal = FALSE;
int *p = NULL;
p = new int;
if (p == NULL)
{
cout<<" OOM \n";
goto Exit;
}
// Lot of code...
Exit:
if(p)
{
delete p;
p = NULL;
}
return bRetVal;
}
</code></pre>
<p>This makes it much easier as we can track our clean up code at one section in code, that is, after the Exit label.</p>
<p>However, I have read many places it's bad practice to have goto statements.</p>
<p>Currently I am reading the <em><a href="https://en.wikipedia.org/wiki/Code_Complete" rel="noreferrer">Code Complete</a></em> book, and it says that we need to use variables close to their declarations. If we use goto then we need to declare/initialize all variables before first use of goto otherwise the compiler will give errors that initialization of xx variable is skipped by the goto statement.</p>
<p>Which way is right?</p>
<hr>
<p>From Scott's comment:</p>
<p>It looks like using goto to jump from one section to another is bad as it makes the code hard to read and understand.</p>
<p>But if we use goto just to go forward and to one label then it should be fine(?).</p>

379,175 | <p>I have a <code>Dictionary<string,int></code> that has the potential to contain upwards of 10+ million unique keys. I am trying to reduce the amount of memory that this takes, while still maintaining the functionality of the dictionary.</p>
<p>I had the idea of storing a hash of the string as a long instead, this decreases the apps memory usage to an acceptable amount (~1.5 gig to ~.5 gig), but I don't feel very good about my method for doing this. </p>
<pre><code>long longKey=
BitConverter.ToInt64(cryptoTransformSHA1.ComputeHash(enc.GetBytes(strKey)), 0);
</code></pre>
<p>Basically this chops off the end of a SHA1 hash, and puts the first chunk of it into a long, which I then use as a key. While this works, at least for the data I'm testing with, I don't feel like this is a very reliable solution due to the increased possibility for key collisions. </p>
<p>Are there any other ways of reducing the Dictionary's memory footprint, or is the method I have above not as horrible as I think it is?</p>
<p>[edit]
To clarify, I need to maintain the ability to lookup a value contained in the Dictionary using a string. Storing the actual string in the dictionary takes way to much memory. What I would like to do instead is to use a <code>Dictionary<long,int></code> where the long is the result of a hashing function on the string.</p>

379,231 | <p>I've been developing Web applications for a while now and have dipped my toe into GUI and Game application development.</p>
<p>In the web application (php for me), a request is made to the file, that file includes all the necessary files to process the info into memory, then the flow is from Top to Bottom for each request. (mainly)</p>
<p>I know that for Games the action happens within the Game Loop, but how are all the different elements of a game layered into that single loop (menu system, gui, loading of assets and the 3d world) with the constant loading and unloading of certain things.</p>
<p>Same for GUI programs, i believe there's an "application loop" of some sorts.</p>
<p>Are most of the items called into memory and then accessed, are the items linked in and loaded into memory when needed?</p>
<p>What helped me develop web applications faster is when i understood the flow of the program, it doesn't have to be detailed, just the general idea or pseudo code.</p>

379,234 | <p>I'm trying to come up with a clean way of sorting a set of strings based on a "sorting template". I apologize if my wording is confusing, but I can't think of a better way to describe it (maybe someone can come up with a better way to describe it after reading what I'm trying to do?).</p>
<p>Consider the following list of strings (my "sort template", each item in the list a "command"):</p>
<ul>
<li>[FA, TY, AK, PO, PR, ZZ, QW, BC]</li>
</ul>
<p>I'd like to use the order of the strings within that list to sort a list of those commands. For example, I'd like the following list:</p>
<ul>
<li>[TY, PR, PR, ZZ, BC, AK]</li>
</ul>
<p>to be sorted into the following list based on the "sorting template":</p>
<ul>
<li>[TY, AK, PR, PR, ZZ, BC]</li>
</ul>

The best idea I have yet is to use an enumeration...</p>

<p>...and do an Enum.Parse() on each command in my list I want sorted, converting that list from a list of strings into a list of Commands, which would then be sorted based on the order of the enumeration.</p>
<p>I don't know. The enumeration seems like it would work, but is there a better way I could go about this?</p>

379,238 | <p>My project is about to introduce SOAP. It's going to be used for C++ <-> Java and C++ <-> Flex communication. I'm responsible for refactoring our apps to take advantage of Java business rules engine and new Flex gui.</p>
<p>What resources are must read for C++ SOAP? I've read W3 materials. We're probably be using gSOAP on Solaris boxes.</p>

379,239 | <p>in asp.net 2.0 (not mvc), the form's action is to itself. how can I use the forms plugin to send information to server?
I need to send data from the form (let's say name, email, comment) and to display the result on the client side.
Any ideas?</p>
<p>Thanks,
Dave</p>

379,240 | <p>Assuming I have fonts installed which have the appropriate glyphs in them, is there a command shell for Windows XP that will display Unicode characters? At a minimum, two things that should display Unicode correctly:</p>
<ul>
<li>Directory listings. I don't care what I have to type (dir, ls, get-childitem, etc.), so long as files with Unicode characters in their names appear with the right glyphs, not the unprintable character box.</li>
<li>Text file content listings. Again, doesn't matter to me if it's 'less', 'more', 'cat', 'dog', etc., so long as the characters are printed. I recognize that this is more complicated because of character encoding of the file, so if I have to specify that on the command line that's fine with me.</li>
</ul>
<p>Here's what I've tried so far:</p>
<ul>
<li>cmd.exe</li>
<li>Windows PowerShell; including the multilingual version.</li>
<li>Cygwin bash</li>
</ul>
<p>No luck. I even tried installing <a href="http://blogs.msdn.com/powershell/archive/2006/10/16/Windows-PowerShell-Font-Customization.aspx" rel="noreferrer">custom fonts for cmd/PowerShell</a>. PowerShell and cmd.exe seem to be Unicode-aware in the sense that I can copy/paste the non-printable box out of there and it will paste into other apps with the correct characters. Cygwin (?) seems to convert to the ? character and that comes through in the copy/paste.</p>
<p>Any ideas?</p>

<p>It works fine if I hard code the username/password, and fails when I try and access the app.config</p>

379,282 | <p>In the C# example of polymorphism, there is a Cat class which inherits a class called AnimalBase and an interface called IAnimal.</p>
<p>The link in question is: <a href="http://en.wikipedia.org/wiki/Polymorphism_in_object-oriented_programming" rel="nofollow noreferrer">http://en.wikipedia.org/wiki/Polymorphism_in_object-oriented_programming</a></p>
<p>My question is, why is both a base class and an interface used? Why not one or the other? I was of the school of thought that only an abstract class would be required for implementing polymorphism.</p>
<p>Thanks</p>

379,328 | <p>I want in a good performance way (I hope) replace a named parameter in my string to a named parameter from code, example, my string:</p>
<pre><code>"Hi {name}, do you like milk?"
</code></pre>
<p>How could I replace the {name} by code, Regular expressions? To expensive? Which way do you recommend?</p>
<p>How do they in example NHibernates HQL to replace :my_param to the user defined value? Or in ASP.NET (MVC) Routing that I like better, "{controller}/{action}", new { controller = "Hello", ... }?</p>

379,339 | <p>I am using <a href="http://htmlpurifier.org" rel="nofollow noreferrer">HTML Purifier</a> in my PHP project and am having trouble getting it to work properly with user input.</p>
<p>I am having users enter in HTML using a WYSIWYG editor (<a href="http://tinymce.moxiecode.com/" rel="nofollow noreferrer">TinyMCE</a>), but whenever a user enters in the HTML entity <code>&nbsp;</code> (non-breaking space) it gets saved into the database as this weird foreign character (<code>Â</code>).</p>
<p>However, the thing is, when I edit the saved entry using the WYSIWYG editor it gets displayed properly as <code>&nbsp;</code>. It also functions properly when displayed, only that in the source code it appears as a real space, but not the non-breaking space character.</p>
<p>Also, in the MySQL database it displays as the weird foreign character.</p>
<p>I read the doc about <a href="http://htmlpurifier.org/docs/enduser-utf8.html" rel="nofollow noreferrer">Unicode and HTML Purifier</a> and changed my database and web page encoding to be UTF-8, but I am still having problems with the non-breaking space character not being mangled. The other HTML entities, such as <code>&lt;</code> and <code>&gt;</code>, get saved as <code><</code> and <code>></code>, but why not <code>&nbsp;</code>?</p>

379,342 | <p>I have a site where users can post stuff (as in forums, comments, etc) using a customised implementation of TinyMCE. A lot of them like to copy & paste from Word, which means their input often comes with a plethora of associated MS inline formatting.</p>
<p>I can't just get rid of <code><span whatever></code> as TinyMCE relies on the span tag for some of it's formatting, and I can't (and don't want to) force said users to use TinyMCE's "Paste From Word" feature (which doesn't seem to work that well anyway).</p>
<p>Anyone know of a library/class/function that would take care of this for me? It must be a common problem, though I can't find anything definitive. I've been thinking recently that a series of brute-force regexes looking for MS-specific patterns might do the trick, but I don't want to re-write something that may already be available unless I must.</p>
<p>Also, fixing of curly quotes, em-dashes, etc would be good. I have my own stuff to do this now, but I'd really just like to find one MS-conversion filter to rule them all.</p>

379,343 | <p>It seems to me its very easy to implement an implicit operator versus a TypeConverter, so I'm assuming they aren't equivalent because of the prevalence of TypeConverters in the framework (see anything that extends FrameworkElement).</p>
<p>But why? Wouldn't it have been much easier to create string->object and object->string implicit operators and take advantage of those in serialization (both XML and XAML)?</p>
<p>Is it YAGNI? Single responsibility? Because you can't specify operator overloads in interfaces?</p>
