On the File menu, point to New, and then click Project to open the New Project dialog box.

Expand the Visual C++ node, and select CLR.

Click the CLR Console Application icon.

Change the name of the project to TempConvertClient3.

Click OK to create the project.

From Solution Explorer, select the TempConvert3Client project node. On the Project menu, click Add Web Reference.

In the URL box of the Add Web Reference dialog box, type the URL to obtain the service description of the XML Web service you want to access, such as http://localhost/TempConvert3WebSetup/TempConvert3.asmx. Then click the Go button to retrieve information about the XML Web service.

- or -

If the XML Web service exists on the local machine, click the Web services on the local machine link in the browser pane. Then click the link for the TempConvert3 XML Web service from the list provided to retrieve information about the XML Web service.

In the Web reference name box, rename the Web reference to ConvertSvc, which is the namespace you will use for this Web reference.

Click Add Reference to add a Web reference for the target XML Web service. For more information, see How to: Add and Remove Web References.

Visual Studio downloads the service description and adds it to your project. Then it generates a proxy class and compiles a DLL from the service description. Finally, Visual Studio adds a new header file, WebService.h, to your project. This header file references the necessary namespaces of the .NET Framework for using XML Web services and the DLL it created. If you explore the local project directory, you will also find the Visual C# source file for the DLL.

In Solution Explorer, locate TempConvertClient3.cpp in the Source Files folder and open this file for editing.

Replace the contents of this file with the following:

#include "stdafx.h"
#include "WebService.h"

using namespace System;

int main(void)
{
    while (true)
    {
        try
        {
            ConvertSvc::TempConvert3Class^ proxy =
                gcnew ConvertSvc::TempConvert3Class();
            Console::Write("Temperature in degrees Fahrenheit: ");
            System::String^ sInput = Console::ReadLine();
            double dFahrenheit = System::Convert::ToDouble(sInput);
            double dCelsius = proxy->ConvertTemperature(dFahrenheit);
            Console::Write("Temperature in degrees Celsius: ");
            Console::WriteLine(dCelsius.ToString());
        }
        catch (System::FormatException^ e)
        {
            Console::WriteLine("Invalid value...exiting: {0}", e->Message);
            break;
        }
    }
    return 0;
}

Note
The name of the XML Web service class generated when adding a Web reference may differ from the one shown above as TempConvert3Class.

Save the solution.

On the Build menu, click Build Solution.

In the Code Editor, place the cursor on the line of code that calls the proxy function:

double dCelsius = proxy->ConvertTemperature(dFahrenheit);

Press F9 to place a breakpoint on this line of code.

— Or —

Click to the left of that line of code in the indicator margin.

For more information, see How to: Debug Code in the Editor.

On the Debug menu, click Start Debugging.

This command instructs Visual Studio to run the application in the debugger. Visual Studio builds the project and launches the application.

In the console window, type the number 212 and press Enter.

When processing reaches the breakpoint, processing stops. The Visual Studio debugger highlights the line containing the breakpoint and while halted, you can perform a variety of tasks. For more information, see Debugger Roadmap and Viewing Data in the Debugger.

On the Debug menu, click Continue to continue processing.

The application creates a SOAP request message, which it sends to the XML Web service. In return, the application receives a SOAP response message. The application then parses the response and displays a message indicating that 212 degrees Fahrenheit is the equivalent of 100 degrees Celsius.

To stop running the application and return to the Code Editor, on the Debug menu, click Stop Debugging.

On the Debug menu, click Delete All Breakpoints.
