Probably it is a trivial question, but the answer is not always obvious. The main rule is to follow the right link like this: https://www.java.com/en/download/help/firefox_online_install.xml. As the result you will get:

I’ve been working on some MFC application and to apply my WPF knowledge I added a WPF control written in C# to my MFC CView with the following code:
int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
try
{
gcroot<hwndsource ^> hwnd_source = gcnew HwndSource(0, WS_VISIBLE | WS_CHILD, 0, 0, 0, "HwndSource", IntPtr(m_hWnd));
MyWpfControl ^ control = gcnew MyWpfControl();
hwnd_source->RootVisual = control;
}
catch (Exception ^ ex)
{
String ^ msg = ex->Message;
}
return 0;
}
All that I needed to do is to follow the steps described in this post: How do I host WPF content in MFC Applications, fix VS2012 bug described here, and got rid of std::mutex and std::lock_guard replacing them with the following classes using typedefs:
It could be useful sometimes to know what variables are defined at particular point of PHP script in order to have a better understanding of the code you are debugging. In contrast with C++, PHP has a magic function get_defined_vars ( void ) that returns an array of all defined variables with their values so we can output all variable names with the following line of code:
print_r(array_keys(get_defined_vars()));
Fortunately, to compile BOOST with MS VC 2010 we need Visual Studio Command Prompt and five commands:
Navigate to BOOST directory, for example:
F: cd F:\Projects\Lib\boost_1_53_0
I believe that the simplest way to pass complex data from C# to PHP is through WCF service. See my previous post How to implement WCF service in PHP for more details.
Let assume we have a WCF service contract that has the following method with some nested dictionary as a parameter:
[ServiceContract]
public interface IStore
{
[OperationContract]
void UpdateRows(Dictionary<int, Dictionary<string, object>> rows);
}
Below I provided the sample implementation of UpdateRows in PHP that iterates through nested dictionaries (first level called ‘rows’ and second level called ‘properties’):
A long time ago, STL had auto_ptr<Type> class that automatically deleted a dynamically allocated C++ object when control leaves a block. Personally, I believe that auto_ptr<Type> was typically used in simple scenarios as a local variable or a class member but theoretically it is even possible to declare a vector of auto_ptr<Type> because auto_ptr<Type> stores an ownership indicator and its copy constructor transfers the ownership from the instance being copied, so vector::push_back(…) and vector::resize(…) functions works correctly.
Today I implemented my first PHP Web Service and successfully used it by C# client or, more precisely, I created WCF service contract in C# and implemented it in PHP. A new option “singlewsdl” in WCF 4.5 helped me a lot. Using this option I generated the service description as a single WSDL-file without additional XSD-files containing the data contracts of the service. Then I uploaded this WSDL-file on my Web Server and written PHP code for all the methods of the service.
While investigating how to make C# and PHP interact with each other I run into an interesting extension of WCF Service Model for working over XML-RPC protocol. I played a bit with this extension and after fixing some bug in its source code I made it work with my little custom XML-RPC server implemented as Joomla XML-RPC plugin.
While investigating how to create a Web Service in PHP I run into NuSoap library, that can generate WSDL based on some matadata describing Web Service method signatures and the data structures. I downloaded NuSoap library and found some trivial sample that started working after adding the highlighted line of code:
The first thing that we need to do to use millimeters in XAML is to define simple Mm2PixelConverter class that performs the conversion from millimeter to pixels:
[ValueConversion(typeof(double), typeof(double))]
class Mm2PixelConverter : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
double mm = (double)value;
return WinUtil.Mm2Pixel(mm);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
#endregion
}
