And a slightly slower search turns up the blog post &quot;[CSS parser class in .NET](http://blog.dynamicprogrammer.com/2008/01/20/CSSParserClassInNET.aspx)&quot; which embeds [this gist on GitHub](https://gist.github.com/561823) (in case the blog ever dies).

There is a CSS grammar file for GoldParser:

http://goldparser.org/grammars/files/css.zip

GoldParser is easy to include in a C# project, and generates an real LALR parser - not some regex hack.

Have you tried the [one featured in JsonFx][1]? It&#39;s written in C#, parses CSS3 syntax and is distributed under a MIT style license.


  [1]: http://code.google.com/p/jsonfx/source/browse#svn/trunk/JsonFx/JsonFx.BuildTools/CssCompactor

I wrote one, using the grammar specified in the CSS 2.1 spec. I have also released it now: for details, see http://www.modeltext.com/css/

[Here][1] you can find another one especially for C# with sample source.

I&#39;m trying to run the following command:

    find . -iname &#39;.#*&#39; -print0 | xargs -0 -L 1 foobar

where &quot;foobar&quot; is an alias or function defined in my .bashrc file (in my case, it&#39;s a function that takes one parameter).  Apparently xargs doesn&#39;t recognize these as things it can run.  Is there a clever way to remedy this?

I have been doing some OO Perl programming and I was wondering: which is the best way to perform unit tests?

So far I have been using the [Test::Simple][1] module to perform tests, but it feels 
insufficient for what I want. 

Can you point me to some nice modules for that?

Is it possible to pass parameters with an `HTTP` get request? If so, how should I then do it? I have found an `HTTP` post requst ([link][1]). In that example the string `postData` is sent to a webserver. I would like to do the same using *get* instead. Google found this example on `HTTP` get [here][2]. However no parameters are sent to the web server.

Recently I&#39;ve been thinking about securing some of my code. I&#39;m curious how one could make sure an object can never be created directly, but only via some method of a factory class. Let us say I have some &quot;business object&quot; class and I want to make sure any instance of this class will have a valid internal state. In order to achieve this I will need to perform some check before creating an object, probably in its constructor. This is all okay until I decide I want to make this check be a part of the business logic. So, how can I arrange for a business object to be creatable only through some method in my business logic class but never directly? The first natural desire to use a good old &quot;friend&quot; keyword of C++ will fall short with C#. So we need other options...

Let&#39;s try some example:

    public MyBusinessObjectClass
    {
        public string MyProperty { get; private set; }
    
        public MyBusinessObjectClass (string myProperty)
        {
            MyProperty = myProperty;
        }
    }
    
    public MyBusinessLogicClass
    {
        public MyBusinessObjectClass CreateBusinessObject (string myProperty)
        {
            // Perform some check on myProperty
    
            if (true /* check is okay */)
                return new MyBusinessObjectClass (myProperty);
    
            return null;
        }
    }

It&#39;s all okay until you remember you can still create MyBusinessObjectClass instance directly, without checking the input. I would like to exclude that technical possibility altogether.

So, what does the community think about this?

I&#39;m using log4net to log write log message to a rolling log file. 

Now I would also redirect all trace messages from &lt;code&gt;System.Diagnostics.Trace&lt;/code&gt; to that log file. How can I configure that? I tried to find anything about that in the log4net documentation, but without success. Is it possible at all?

The reason I want to do that is because I am interested in the Trace messages of a 3rd party library.

How to log Trace messages with log4net?

I have a combobox in C# and I want to use auto complete suggestions with it, however I want to be able to change the auto complete entries as the user types, because the possible valid entries are far too numerous to populate the `AutoCompleteStringCollection` at startup.

As an example, suppose I&#39;m letting the user type in a name.  I have a list of possible first names (&quot;Joe&quot;, &quot;John&quot;) and a list of surnames (&quot;Bloggs&quot;, &quot;Smith&quot;), but if I have a thousand of each, then that would be a million possible strings - too many to put in the auto complete entries.  So initially I want to have just the first names as suggestions (&quot;Joe&quot;, &quot;John&quot;) , and then once the user has typed the first name, (&quot;Joe&quot;), I want to remove the existing auto complete entries and replace them with a new set consisting of the chosen first name followed by the possible surnames (&quot;Joe Bloggs&quot;, &quot;Joe Smith&quot;).  In order to do this, I tried the following code:

    void InitializeComboBox()
    {
        ComboName.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        ComboName.AutoCompleteSource = AutoCompleteSource.CustomSource;
        ComboName.AutoCompleteCustomSource = new AutoCompleteStringCollection();
        ComboName.TextChanged += new EventHandler( ComboName_TextChanged );
    }
    
    void ComboName_TextChanged( object sender, EventArgs e )
    {
        string text = this.ComboName.Text;
        string[] suggestions = GetNameSuggestions( text );

        this.ComboQuery.AutoCompleteCustomSource.Clear();
        this.ComboQuery.AutoCompleteCustomSource.AddRange( suggestions );
    }

However, this does not work properly.  It seems that the call to Clear() causes the auto complete mechanism to &quot;turn off&quot; until the next character appears in the combo box, but of course when the next character appears the above code calls Clear() again, so the user never actually sees the auto complete functionality.  It also causes the entire contents of the combo box to become selected, so between every keypress you have to deselect the existing text, which makes it unusable.  If I remove the call to Clear() then the auto complete works, but it seems that then the `AddRange()` call has no effect, because the new suggestions that I add do not appear in the auto complete dropdown.

I have been searching for a solution to this, and seen various things suggested, but I cannot get any of them to work - either the auto complete functionality appears disabled, or new strings do not appear.  Here is a list of things I have tried:

- Calling `BeginUpdate()` before changing the strings and `EndUpdate()` afterward.
- Calling `Remove()` on all the existing strings instead of Clear().
- Clearing the text from the combobox while I update the strings, and adding it back afterward.
- Setting the `AutoCompleteMode` to &quot;None&quot; while I change the strings, and setting it back to &quot;SuggestAppend&quot; afterwards.
- Hooking the` TextUpdate` or `KeyPress` event instead of `TextChanged`.
- Replacing the existing `AutoCompleteCustomSource` with a new `AutoCompleteStringCollection` each time.

None of these helped, even in various combinations.  [Spence](https://stackoverflow.com/users/53771/spence) suggested that I try overriding the `ComboBox` function that gets the list of strings to use in auto complete.  Using a reflector I found a couple of methods in the `ComboBox` class that look promising - `GetStringsForAutoComplete()` and `SetAutoComplete()`, but they are both private so I can&#39;t access them from a derived class.  I couldn&#39;t take that any further.

I tried replacing the `ComboBox` with a `TextBox`, because the auto complete interface is the same, and I found that the behaviour is slightly different. With the `TextBox` it appears to work better, in that the Append part of the auto complete works properly, but the Suggest part doesn&#39;t - the suggestion box briefly flashes to life but then immediately disappears.

So I thought &quot;Okay, I&#39;ll live without the Suggest functionality and just use Append instead&quot;, however when I set the `AutoCompleteMode` to Append, I get an access violation exception. The same thing happens with Suggest - the only mode that doesn&#39;t throw exceptions is `SuggestAppend`, even though the Suggest part doesn&#39;t then behave correctly. 

I thought that it was supposed to be impossible to get access violation exceptions when using C# managed code.  [Avram](https://stackoverflow.com/users/61883/avram) suggested I use &quot;lock&quot; to fix this, but I don&#39;t know what I should lock - the only thing that has a SyncRoot member is the `AutoCompleteStringCollection`, and locking that doesn&#39;t prevent the access violation exceptions. I also tried locking the `ComboBox` or `TextBox`, but that didn&#39;t help either. As I understand it, lock only prevents other locks, so if the underlying code isn&#39;t using lock then my using it won&#39;t make any difference.

The upshot of all this is that I can&#39;t currently use a `TextBox` or a `ComboBox` with dynamic auto complete.  Does anyone have any insights into how I could achieve this?

### Update:

I still haven&#39;t got this working, but I have found out some more.  Maybe some of this will inspire someone else to come up with a solution.

### Update 2:

After trying various other things such as changing the autocomplete in a worker thread, and using `BeginInvoke()` to simulate PostMessage() type behaviour, I finally gave up and just implemented my own auto complete dropdown using a list box.  It&#39;s much more responsive than the built-in one, and I spent less time doing that than I did trying to get the built-in one to work, so the lesson for anyone else who wants this behaviour is - you&#39;re probably better off implementing it yourself.

How can I dynamically change auto complete entries in a C# combobox or textbox?

I&#39;ve come across a few examples recently that do things like:

&lt;!-- language: lang-html --&gt;

    &lt;dl&gt;
      &lt;dt&gt;Full Name:&lt;/dt&gt;
      &lt;dd&gt;&lt;input type=&quot;text&quot; name=&quot;fullname&quot;&gt;&lt;/dd&gt;
      &lt;dt&gt;Email Address:&lt;/dt&gt;
      &lt;dd&gt;&lt;input type=&quot;text&quot; name=&quot;email&quot;&gt;&lt;/dd&gt;
    &lt;/dl&gt;

for doing HTML forms.  Why is that?  What is the advantage over using tables?

Why use definition lists (DL,DD,DT) tags for HTML forms instead of tables?

There have been a few articles recently about Google&#39;s new imageless buttons:

- http://stopdesign.com/archive/2009/02/04/recreating-the-button.html
- http://stopdesign.com/eg/buttons/3.0/code.html
- http://stopdesign.com/eg/buttons/3.1/code.html
- http://gmailblog.blogspot.com/2009/02/new-ways-to-label-with-move-to-and-auto.html

I really like how these new buttons work in Gmail.  How can I use these or similar buttons on my site?  Are there any open source projects with a similar look &amp; feel?

If I wanted to roll my own button package like this using JQuery/XHTML/CSS, what elements could I use?  My initial thoughts are:

1. Standard `&lt;input type=&quot;button&quot;&gt;` with css to improve the look (the design article talked mostly about the css/imges involves.)

2. Jquery javascript to bring up a custom dialog rooted to the button on the &quot;onclick&quot; event which would have `&lt;a&gt;` tags in them and a search bar for filtering?  Would a table layout for that popup be sane?


I&#39;m terrible at reverse engineering things on the web, what are some of the tools that I could use to help reverse engineer these buttons?  Using Firefox&#39;s web developer toolbar I can&#39;t really see the css or javascript (even if it is minified) that is used on the buttons popup dialogs.  What browser tool or other method could I use to peek at them and get some ideas?

I&#39;m not looking to steal any of Google&#39;s IP, just get an idea of how I could create similar button functionality.

Google&#39;s Imageless Buttons

Ok, I had a simple layout problem a week or two ago.  Namely sections of a page needed a header:

&lt;!-- language: lang-none --&gt;

    +---------------------------------------------------------+
    | Title                                            Button |
    +---------------------------------------------------------+

Pretty simple stuff.  Thing is table hatred seems to have taken over in the Web world, which I was reminded of when I asked [Why use definition lists (DL,DD,DT) tags for HTML forms instead of tables?][1]  Now the general topic of tables vs divs/CSS has previously been discussed, for example:

 - [DIV vs Table][3]; and
 - [Tables instead of DIVs][4].

So this isn&#39;t intended to be a general discussion about CSS vs tables for layout.  This is simply the solution to one problem.  I tried various solutions to the above using CSS including:

 - Float right for the button or a div containing the button;
 - Position relative for the button; and
 - Position relative+absolute.

None of these solutions were satisfactory for different reasons.  For example the relative positioning resulted in a z-index issue where my dropdown menu appeared under the content.

So I ended up going back to:

&lt;!-- language: lang-html --&gt;

    &lt;style type=&quot;text/css&quot;&gt;
    .group-header { background-color: yellow; width: 100%; }
    .group-header td { padding: 8px; }
    .group-title { text-align: left; font-weight: bold; }
    .group-buttons { text-align: right; }
    &lt;/style&gt;
    &lt;table class=&quot;group-header&quot;&gt;
    &lt;tr&gt;
      &lt;td class=&quot;group-title&quot;&gt;Title&lt;/td&gt;
      &lt;td class=&quot;group-buttons&quot;&gt;&lt;input type=&quot;button&quot; name=&quot;Button&quot;&gt;&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;

And it works perfectly.  It&#39;s simple, as backward compatibile as it gets (that&#39;ll work probably even on IE5) and it just works.  No messing about with positioning or floats.

So can anyone do the equivalent without tables?

The requirements are:

 - **Backwards compatible:** to FF2 and IE6;
 - **Reasonably consistent:** across different browsers;
 - **Vertically centered:** the button and title are of different heights; and
 - **Flexible:** allow reasonably precise control over positioning (padding and/or margin) and styling.

On a side note, I came across a couple of interesting articles today:

 - [Why CSS should not be used for layout][5]; and
 - [Tables vs CSS: CSS Trolls begone][6]

**EDIT:** Let me elaborate on the float issue.  This sort of works:

&lt;!-- language: lang-html --&gt;

    &lt;html&gt;
      &lt;head&gt;
        &lt;title&gt;Layout&lt;/title&gt;
        &lt;style type=&quot;text/css&quot;&gt;
          .group-header, .group-content { width: 500px; margin: 0 auto; }
          .group-header { border: 1px solid red; background: yellow; overflow: hidden; }
          .group-content { border: 1px solid black; background: #DDD; }
          .group-title { float: left; padding: 8px; }
          .group-buttons { float: right; padding: 8px; }
        &lt;/style&gt;
      &lt;/head&gt;
      &lt;body&gt;
        &lt;div class=&quot;group-header&quot;&gt;
          &lt;div class=&quot;group-title&quot;&gt;This is my title&lt;/div&gt;
          &lt;div class=&quot;group-buttons&quot;&gt;&lt;input type=&quot;button&quot; value=&quot;Collapse&quot;&gt;&lt;/div&gt;
        &lt;/div&gt;
        &lt;div class=&quot;group-content&quot;&gt;
          &lt;p&gt;And it works perfectly. It&#39;s simple, as backward compatibile as it gets (that&#39;ll work probably even on IE5) and it just works. No messing about with positioning or floats.&lt;/p&gt;
          &lt;p&gt;So can anyone do the equivalent without tables that is backwards compatible to at least FF2 and IE6?&lt;/p&gt;
          &lt;p&gt;On a side note, I came across a couple of interesting articles today:&lt;/p&gt;
        &lt;/div&gt;
      &lt;/body&gt;
    &lt;/html&gt;

Thanks to [Ant P][7] for the `overflow: hidden` part (still don&#39;t get why though).  Here&#39;s where the problem comes in.  Say I want the title and button to be vertically centered.  This is problematic because the elements are of different height.  Compare this to:

&lt;!-- language: lang-html --&gt;

    &lt;html&gt;
      &lt;head&gt;
        &lt;title&gt;Layout&lt;/title&gt;
        &lt;style type=&quot;text/css&quot;&gt;
          .group-header, .group-content { width: 500px; margin: 0 auto; }
          .group-header { border: 1px solid red; background: yellow; overflow: hidden; }
          .group-content { border: 1px solid black; background: #DDD; }
          .group-header td { vertical-align: middle; }
          .group-title { padding: 8px; }
          .group-buttons { text-align: right; }
        &lt;/style&gt;
      &lt;/head&gt;
      &lt;body&gt;
        &lt;table class=&quot;group-header&quot;&gt;
        &lt;tr&gt;
          &lt;td class=&quot;group-title&quot;&gt;This is my title&lt;/td&gt;
          &lt;td class=&quot;group-buttons&quot;&gt;&lt;input type=&quot;button&quot; value=&quot;Collapse&quot;&gt;&lt;/td&gt;
        &lt;/tr&gt;
        &lt;/table&gt;
        &lt;div class=&quot;group-content&quot;&gt;
          &lt;p&gt;And it works perfectly. It&#39;s simple, as backward compatibile as it gets (that&#39;ll work probably even on IE5) and it just works. No messing about with positioning or floats.&lt;/p&gt;

      &lt;/body&gt;
    &lt;/html&gt;

Can you do this HTML layout without using tables?

I&#39;m looking for a way to insert a `&lt;style&gt;` tag into an HTML page with JavaScript.

The best way I found so far:

    var divNode = document.createElement(&quot;div&quot;);
    divNode.innerHTML = &quot;&lt;br&gt;&lt;style&gt;h1 { background: red; }&lt;/style&gt;&quot;;
    document.body.appendChild(divNode);

This works in Firefox, Opera and Internet Explorer but not in Google Chrome. Also it&#39;s a bit ugly with the `&lt;br&gt;` in front for IE.

Does anyone know of a way to create a `&lt;style&gt;` tag that

 1. Is nicer

 2. Works with Chrome?

Or maybe

 1. This is a non-standard thing I should avoid

 2. Three working browsers are great and who uses Chrome anyway?

What are some good tools for getting a quick start for parsing and analyzing C/C++ code?

In particular, I&#39;m looking for open source tools that handle the C/C++ preprocessor and language.  Preferably, these tools would use lex/yacc (or flex/bison) for the grammar, and not be too complicated.  They should handle the latest ANSI C/C++ definitions.

Here&#39;s what I&#39;ve found so far, but haven&#39;t looked at them in detail (thoughts?):

 - [CScope][1] - Old-school C analyzer.  Doesn&#39;t seem to do a full parse, though.  Described as a glorified &#39;grep&#39; for finding C functions.
 - [GCC][2] - Everybody&#39;s favorite open source compiler.  Very complicated, but seems to do it all.  There&#39;s a related project for creating GCC extensions called [GEM][3], but hasn&#39;t been updated since GCC 4.1 (2006).
 - [PUMA][4] - The PUre MAnipulator.  (from the page: &quot;The intention of this project is to
provide a library of classes for the analysis and manipulation of C/C++ sources. For this
purpose PUMA provides classes for scanning, parsing and of course manipulating C/C++
sources.&quot;).  This looks promising, but hasn&#39;t been updated since 2001.  Apparently PUMA has been incorporated into [AspectC++][5], but even this project hasn&#39;t been updated since 2006.
 - Various C/C++ raw grammars.  You can get [c-c++-grammars-1.2.tar.gz][6], but this has been unmaintained since 1997.  A little Google searching pulls up other basic lex/yacc grammars that could serve as a starting place.
 - Any others?

I&#39;m hoping to use this as a starting point for translating C/C++ source into a new toy language.

Thanks!
-Matt

(Added 2/9): Just a clarification: I want to extract semantic information from the preprocessor in addition to the C/C++ code itself.  I don&#39;t want &quot;#define foo 42&quot; to disappear into the integer &quot;42&quot;, but remain attached to the name &quot;foo&quot;.  This, unfortunately, excludes several solutions that run the preprocessor first and only deliver the C/C++ parse tree)

      Convert.ToDouble(regionData, CultureInfo.CurrentCulture);
      dic.Add(key, regionData.ToString());
    }
    catch (InvalidCastException)
    {
      // is not a number
    }
or

    double d;
    string str = data.ToString();
    if (Double.TryParse(str, out d)) // if done, then is a number
    {
      dic.Add(key, str);
    }

I have to use `StringDictionary` instead of `Dictionary&lt;string, double&gt;` because of the following parsing algorithm issues.

My questions: Which way is faster? Which is safer?

And is it better to call `Convert.ToDouble(object)` or `Convert.ToDouble(string)` ?

Double.TryParse or Convert.ToDouble - which is faster and safer?

&gt; Edit: I recently learned about a project called CommonMark, which
&gt; correctly identifies and deals with the ambiguities in the original
&gt; Markdown specification. http://commonmark.org/ It has great C# library
&gt; support.

You can find the syntax [here][1].

The source that follows with the download is written in [Perl][2], which I have no intentions of honoring. It is riddled with regular expressions, and it relies on [MD5][3] hashes to escape certain characters. Something is just wrong about that!

I&#39;m about to hard code a parser for [Markdown][4]. What is experience with this?

If you don&#39;t have anything meaningful to say about the actual parsing of Markdown, spare me the time. (This might sound harsh, but yes, I&#39;m looking for insight, not a solution, that is, a third-party library).

To help a bit with the answers, regular expressions are meant to **identify patterns**! NOT to parse an entire grammar. That people consider doing so is foobar.

* If you think about Markdown, it&#39;s fundamentally based around the concept of paragraphs.
* As such, a reasonable approach might be to split the input into paragraphs. 
* There are many kinds of paragraphs, for example, heading, text, list, blockquote, and code.
* The challenge is thus to identify these paragraphs and in what context they occur.

I&#39;ll be back with a solution, once I find it&#39;s worthy to be shared.

How would you go about parsing Markdown?

In Java, given a `java.net.URL` or a `String` in the form of `http://www.example.com/some/path/to/a/file.xml` , what is the easiest way to get the file name, minus the extension? So, in this example, I&#39;m looking for something that returns `&quot;file&quot;`. 

I can think of several ways to do this, but I&#39;m looking for something that&#39;s easy to read and short.
