The Visual C++ Weekly Vol. 1 Issue 5 (Jan 29, 2011)

Posted: 29 Jan 2011 01:54 PM PST

This week comes with an article to help you set your application for parallelization; C++ MVP Dan Rollins researches on various ways to implement properties in C++; Issam Iqbal, C++ MVP, gives another twist to the TO CLI or NOT TO CLI debate when creating unit tests for our unmanaged code (voting for "NOT TO CLI"). There are also a couple of code samples, one for creating Dynamic Link Libraries and the other one on Internationalization. We are also complementing for the first time our C++ coverage with entrepreneurial stuff for micro independent software vendors (micro ISVs, organizations composed for as few people as one –yourself- and as many as… few anyway). Read all that and more in the latest issue of The Visual C++ Weekly.

HTML5 & CSS3 in Visual Studio 2010 SP1

Posted: 27 Jan 2011 03:47 PM PST

Since the release of Visual Studio 2010 SP1 beta last month, there has been a lot of questions regarding the support for HTML5 and CSS3. HTML5 Visual Studio 2010 was originally released without HTML5 support, so does SP1 finally add support for it? Yes, to some extent. The entire HTML5 specification isn't supported but most of the new elements and attributes are. That means you get both intellisense and validation for HTML5 with SP1. Turn it on After installing SP1 you have to tell Visual Studio to start using the HTML5 schema. Go to Tools -> Options, and then select Text Editor -> HTML -> Validation . You should now be able to select HTML5 or XHTML5 as the target schema. Or if you have the HTML Source Editing toolbar enabled, you can...(read more)

Heritage Shared

Posted: 28 Jan 2011 12:44 AM PST

A few days ago, we posted two C++ quizzes based on a question posted in a forum. Let's review the first question

 

Quiz 1
  1. #include <iostream>
  2.   
  3. class Foo {
  4. public:
  5.     virtual void DoStuff()=0;
  6. };
  7.   
  8. class Bar : public Foo {
  9. public:
  10.     virtual void DoStuff(int a)=0;
  11. };
  12.   
  13. class Baz : public Bar {
  14. public:
  15.     void DoStuff(int a) override
  16.     {
  17.         std::cout << "Baz::DoStuff(int)";
  18.     }
  19.   
  20.     void DoStuff() override
  21.     {
  22.         std::cout << "Baz::DoStuff()";
  23.     }
  24. };
  25.   
  26. int main() {
  27.     Baz baz;
  28.     Bar *pBar = &baz;
  29.   
  30.     pBar->DoStuff();
  31. }

 

The guy was frustrated because he expected two things:

  • The code would compile without errors.
  • Line 30 would end up by calling Baz::DoStuff() which in turn would have printed that same in the output console.

Instead, he got the following compile-time error at that same line

e:\foo.cpp(30): error C2660: 'Bar::DoStuff' : function does not take 0 arguments

The root of this compilation error is at line 11: as we are closing the definition of class Bar without saying anything about method DoStuff without arguments but, instead, having overloaded DoStuff in line 10 with a version that takes an argument of type int, what we just did was hide the original Foo::Stuff() declaration. With that said, the compilation error makes sense.

The fact that Foo::Stuff() is a pure virtual method is not a necessary condition for this to happen at all. It would have happened with virtual and non-virtual methods as well.

I have the feeling that Java and C# developers may have experienced this when coding artifacts in C++ as, in those languages, this notion of hiding declarations is not available (there's an alternative consisting in declaring members as private, so subclasses won't get them visible, but in that case the decision of what is hidden belongs to the coder of the superclass. In C++, the decision is to be taken by the coder of the derived class.

How could my friend overcome this error in order to get the application working as he expected? By including a using declaration in the definition of Bar like the one at line 5 here:

 

  1. class Bar : public Foo {
  2. public:
  3.     // using introduces a name from a base
  4.     // class into a derived class scope.
  5.     using Foo::DoStuff;
  6.     virtual void DoStuff(int a)=0;
  7. };

 

Now the application runs as initially intended.

Quiz 1 running

In quiz 2, the C++ principle we just reviewed applies as well, but if hiding was not what we wanted to do, this issue could turn into something more dangerous because the application will compile anyway and the undesired behavior will have to be discovered at runtime.

 

Quiz 2
  1. #include <iostream>
  2.   
  3. class Foo {
  4. public:
  5.     virtual void DoStuff(char a)=0;
  6. };
  7.   
  8. class Bar : public Foo {
  9. public:
  10.     virtual void DoStuff(int a)=0;
  11. };
  12.   
  13. class Baz : public Bar {
  14. public:
  15.     void DoStuff(int a) override
  16.     {
  17.         std::cout << "Baz::DoStuff(int)";
  18.     }
  19.   
  20.     void DoStuff(char a) override
  21.     {
  22.         std::cout << "Baz::DoStuff(char)";
  23.     }
  24. };
  25.   
  26. int main() {
  27.     Baz baz;
  28.     Bar *pBar = &baz;
  29.   
  30.     pBar->DoStuff('a');
  31. }

 

Despite the fact that Foo::DoStuff(char) isn't visible in line 30, the 'a' received as argument is implicitly converted to the int type, producing:

Implicit conversion

Again, the solution here is based on a using declaration as before:

 

  1. class Bar : public Foo {
  2. public:
  3.     using Foo::DoStuff;
  4.     virtual void DoStuff(int a)=0;
  5. };

 

Once declared, we just compile, run and… voilà

Quiz 2 fixed

 

As a conclusion, hiding a base class method is neither a bad thing nor something to avoid as long as it's exactly what you wanted to get.

Parallel Programming with Microsoft Visual C++ (Book in Progress)

Posted: 26 Jan 2011 11:28 PM PST

Parallel Programming with MS Visual C++

The patterns & practices group is writing a new guide that will introduce Visual C++ programmers to patterns for including parallelism in their applications. Examples of these patterns are parallel loops, parallel tasks and data aggregation with map-reduce. Each pattern has its own chapter. Each chapter includes a description of the problem, an example of where the pattern is applicable, and code that implements the solution. On this site you will find; a preliminary draft of the book, the accompanying code samples and answers to the end of chapter questions.

The authors just dropped chapters 4 and 5 in CodePlex, looking for feedback by Wednesday February 2nd. You'll get here these draft chapters and information about how to enter a review.
