Recently a client has complained about the appearance of a system font in IE6. Basically th issue is that IE6 doesn&#39;t support font-smoothing/anti-aliasing (I know you can turn it on in an OS setting or something). But someone threw out this gem:

&quot;You can force font anti-alias in css by using pt instead of px.&quot;

I did a quick POC in various browsers and saw no difference. I found one reference to it online, last post on this forum:

http://www.webmasterworld.com/css/3280638.htm

This sounds like the equivalent of a web developer urban myth, my feeling is it&#39;s BS. Has anyone ever encountered it?

What is the need for the conditional operator? Functionally it is redundant, since it implements an if-else construct. If the conditional operator is more efficient than the equivalent if-else assignment, why can&#39;t if-else be interpreted more efficiently by the compiler?

What does the `#DEN` signify/stand for?

I have been programming in C# for a while and now I want to brush up on my C++ skills. 

Having the class:

    class Foo
    {
        const std::string&amp; name_;
        ...
    };

What would be the best approach (I only want to allow read access to the name_ field):

 - use a getter method: `inline const std::string&amp; name() const { return name_; }`
 - make the field public since it&#39;s a constant

Thanks.

As an extension to this question [Are `const_iterators` faster?][1], I have another question on `const_iterators`. How to remove constness of a `const_iterator`? 
Though iterators are generalised form of pointers but still `const_iterator` and `iterator`s are two different things. Hence, I  believe, I also cannot use `const_cast&lt;&gt;` to covert from `const_iterator` to `iterator`s.

One approach could be that you define an iterator which moves &#39;til the element to which `const_iterator` points. But this looks to be a linear time algorithm.

Any idea on what is the best way to achieve this?

How to remove constness of const_iterator?

I&#39;m trying to export classes from a DLL that contain objects such as `std::vectors` and `std::strings` - the whole class is declared as DLL export through:

    class DLL_EXPORT FontManager {

The problem is that for members of the complex types I get this warning:

&gt;     warning C4251: &#39;FontManager::m__fonts&#39; : class &#39;std::map&lt;_Kty,_Ty&gt;&#39; needs to have dll-interface to be used by clients of class &#39;FontManager&#39;
&gt;           with
&gt;           [
&gt;               _Kty=std::string,
&gt;               _Ty=tFontInfoRef
&gt;           ]


I&#39;m able to remove some of the warnings by putting the following forward class declaration before them even though I&#39;m not changing the type of the member variables themselves:

    template class DLL_EXPORT std::allocator&lt;tCharGlyphProviderRef&gt;;
    template class DLL_EXPORT std::vector&lt;tCharGlyphProviderRef,std::allocator&lt;tCharGlyphProviderRef&gt; &gt;;
    std::vector&lt;tCharGlyphProviderRef&gt; m_glyphProviders;

Looks like the forward declaration &quot;injects&quot; the `DLL_EXPORT` for when the member is compiled but is it safe?  
Does it really change anything when the client compiles this header and uses the `std::` container on his side?  
Will it make all future uses of such a container `DLL_EXPORT` (and possibly not inline)?  
And does it really solve the problem that the warning tries to warn about?

Is this warning anything I should be worried about or would it be best to disable it in the scope of these constructs?  
The clients and the DLL will always be built using the same set of libraries and compilers and those are header only classes...

I&#39;m using Visual Studio 2003 with the standard STD library.

### Update

I&#39;d like to target you more though as I see the answers are general and here we&#39;re talking about std containers and types (such as `std::string`) - maybe the question really is:

Can we disable the warning for standard containers and types available to both the client and the DLL through the same library headers and treat them just as we&#39;d treat an `int` or any other built-in type? (It does seem to work correctly on my side)  
If so would should be the conditions under which we can do this?

Or should maybe using such containers be prohibited or at least ultra care taken to make sure no assignment operators, copy constructors etc will get inlined into the DLL client?

In general I&#39;d like to know if you feel designing a DLL interface having such objects (and for example using them to return stuff to the client as return value types) is a good idea or not and why, I&#39;d like to have a &quot;high level&quot; interface to this functionality...  
Maybe the best solution is what Neil Butterworth suggested - creating a static library?

Exporting classes containing `std::` objects (vector, map etc.) from a DLL

I’m aware of the tutorial at boost.org addressing this: 
[Boost.org Signals Tutorial][1], but the examples are not complete and somewhat over simplified.  The examples there don’t show the include files and some sections of the code are a little vague.
  
**Here is what I need:**  
ClassA raises multiple events/signals  
ClassB subscribes to those events (Multiple classes may subscribe)  
  
In my project I have a lower-level message handler class that raises events to a business class that does some processing of those messages and notifies the UI (wxFrames). I need to know how these all might get wired up (what order, who calls who, etc).

Which is better (or faster), a C++ `for` loop or the `foreach` operator provided by Qt? For example, the following condition

    QList&lt;QString&gt; listofstrings;

Which is better?

    foreach(QString str, listofstrings)
    {
        //code
    }

or
   
    int count = listofstrings.count();
    QString str = QString();
    for(int i=0;i&lt;count;i++)
    {
        str = listofstrings.at(i);
        //Code
    }

When I create and compile a &quot;Hello, World!&quot; application in C#, I get three files in the Debug folder apart from the main exe (e.g. HelloWorld.exe)

1. HelloWorld.vshost.exe
2. HelloWorld.pdb
3. HelloWorld.vshost.exe.manifest

What purpose do these files serve?

Is it possible to add messages to  the built-in error console of Firefox from JavaScript code running in web pages?

I know that I there&#39;s Firebug, which provides a `console` object and its own error console, but I was looking for a quick fix earlier on and couldn&#39;t find anything.

I guess it might not be possible at all, to prevent malicious web pages from spamming the log?

I have IIS 5.1 on a XP machine, and visual studio 2005. How do I go about attaching my debugger to IIS instance.

BTW: I&#39;m not seeing the IIS process within the running processes or probably I don&#39;t know what to look for .

For example:

    BitmapImage bitmap = new BitmapImage();
     
    byte[] buffer = GetHugeByteArray(); // from some external source
    using (MemoryStream stream = new MemoryStream(buffer, false))
    {
        bitmap.BeginInit();
        bitmap.CacheOption = BitmapCacheOption.OnLoad;
        bitmap.StreamSource = stream;
        bitmap.EndInit();
        bitmap.Freeze();
    }

Can you tell me any more about `using`?

**Edit:**

As was discussed in the comments of JaredPar&#39;s post, this question is more concerned with an implementation of `Using` in VS2003.  It was pointed out that `Using` was not introduced until .NET 2.0 (VS2005).  JaredPar posted an equivalent workaround.

I am interested in formatting all the files in a Visual Studio (ver. 2005)  project all at once.

Currently, there is a way to format a single document by doing something like **Edit-&gt;Advanced-&gt;Format Document**. However, I don&#39;t see a single command to format all the files of a project all at once.

Any idea how to do that?

This is driving me crazy. Ever since I installed ReSharper 4, &lt;kbd&gt;F12&lt;/kbd&gt; no longer seems to work. If you look at the all the ReSharper short cuts in the Goto sub menu Declaration doesn&#39;t have any assigned!

The only way I can go to declaration is by using &lt;kbd&gt;Alt&lt;/kbd&gt; and &lt;kbd&gt;`&lt;/kbd&gt; and then selecting Declaration. 

I have tried un-installing and re-installing ReSharper with no luck, I have also, in ReSharper option asked it to use the default Visual Studio Key Bindings but that doesn&#39;t to work either. 

Interestingly, when I do use &lt;kbd&gt;Alt&lt;/kbd&gt; and &lt;kbd&gt;`&lt;/kbd&gt; I actually get two entries for the Declaration option.

Has anyone come across this problem?

I am using Visual Studio 2005 SP1.
