This following procedures show you how to create the sample for Walkthrough: Analyzing C/C++ Code for Defects. The procedures create:

A Visual Studio solution named CppDemo.
A static library project named CodeDefects.
A static library project named Annotations.

The procedures also provide the code for the header and .cpp files for the static libraries.

Create the CppDemo solution and the CodeDefects project

Click the File menu, point to New, and then click New Project.
In the Project types tree list, if Visual C++ is not your default language in VS expand Other Languages.
Expand Visual C++, and then click General.
In Templates, click Empty Project.
In the Name text box, type CodeDefects.
Select the Create directory for solution check box.
In the Solution Name text box, type CppDemo.

Configure the CodeDefects project as a static library

In Solution Explorer, right-click CodeDefects and then click Properties.
Expand Configuration Properties and then click General.
In the General list, select the text in the column next to Target Extension, and then type .lib.
In Project Defaults, click the column next to Configuration Type, and then click Static Lib (.lib).

Add the header and source file to the CodeDefects project

In Solution Explorer, expand CodeDefects, right-click Header Files, click Add, and then click New Item.
In the Add New Item dialog box, click Code, and then click Header File (.h).
In the Name box, type Bug.cpp and then click Add.

Copy the following code and paste it into the Bug.cpp file in the Visual Studio editor.

#include <windows.h>  

//    
//These 3 functions are consumed by the sample  
//  but are not defined. This project cannot be linked!  
//  

bool CheckDomain( LPCSTR );  
HRESULT ReadUserAccount();  

//  
//These constants define the common sizes of the   
//  user account information throughout the program  
//  

const int USER_ACCOUNT_LEN = 256;  
const int ACCOUNT_DOMAIN_LEN = 128;

In Solution Explorer, right-click Source Files, point to New, and then click New Item.
In the Add New Item dialog box, click C++ File (.cpp)
In the Name box, type Bug.cpp and then click Add.

Copy the following code and paste it into the Bug.h file in the Visual Studio editor.

#include <stdlib.h>  
#include "Bug.h"  

// the user account   
TCHAR g_userAccount[USER_ACCOUNT_LEN] = "";  
int len = 0;  

bool ProcessDomain()  
{  
    TCHAR* domain = new TCHAR[ACCOUNT_DOMAIN_LEN];  
    // ReadUserAccount gets a 'domain\user' input from   
    //the user into the global 'g_userAccount'  
    if (ReadUserAccount() )  
    {  

        // Copies part of the string prior to the '\'   
        // character onto the 'domain' buffer  
        for( len = 0 ; (len < ACCOUNT_DOMAIN_LEN) && (g_userAccount[len] != '\0') ; len++  )  
        {  
            if ( g_userAccount[len] == '\\' )   
            {  
                // Stops copying on the domain and user separator ('\')   
                break;  
            }  
            domain[len] = g_userAccount[len];          
        }  
        if((len= ACCOUNT_DOMAIN_LEN) || (g_userAccount[len] != '\\'))  
        {  
            // '\' was not found. Invalid domain\user string.  
            delete [] domain;  
            return false;  
        }  
        else  
        {  
            domain[len]='\0';  
        }  
        // Process domain string  
        bool result = CheckDomain( domain );  

        delete[] domain;  
        return result;  
    }  
    return false;  
}  

int path_dependent(int n)  
{  
    int i;  
    int j;  
    if (n == 0)  
        i = 1;  
    else  
        j = 1;  
    return i+j;   
}

Click the File menu, and then click Save All.

Add the Annotations project and configure it as a static library

In Solution Explorer, click CppDemo, point to Add, and then click New Project.
In the Add New Project dialog box, expand Visual C++, click General, and then click Empty Project.
In the Name text box, type Annotations, and then click Add.
In Solution Explorer, right-click Annotations and then click Properties.
Expand Configuration Properties and then click General.
In the General list, select the text in the column next to Target Extension, and then type .lib.
In Project Defaults, click the column next to Configuration Type, and then click Static Lib (.lib).

Add the header file and source file to the Annotations project

In Solution Explorer, expand Annotations, right-click Header Files, click Add, and then click New Item.
In the Add New Item dialog box, click Header File (.h).
In the Name box, type annotations.h and then click Add.

Copy the following code and paste it into the annotations.h file in the Visual Studio editor.

#include <CodeAnalysis/SourceAnnotations.h>  

struct LinkedList  
{  
    struct LinkedList* next;  
    int data;  
};  

typedef struct LinkedList LinkedList;  

[returnvalue:SA_Post( Null=SA_Maybe )] LinkedList* AllocateNode();

In Solution Explorer, right-click Source Files, point to New, and then click New Item.
In the Add New Item dialog box, click Code and then click C++ File (.cpp)
In the Name box, type annotations.cpp and then click Add.

Copy the following code and paste it into the annotations.cpp file in the Visual Studio editor.

#include <CodeAnalysis/SourceAnnotations.h>  
#include <windows.h>  
#include <stdlib.h>    
#include "annotations.h"  

LinkedList* AddTail( LinkedList *node, int value )  
{  
    LinkedList *newNode = NULL;   

    // finds the last node  
    while ( node->next != NULL )   
    {  
        node = node->next;  
    }  

    // appends the new node  
    newNode = AllocateNode();   
    newNode->data = value;  
    newNode->next = 0;  
    node->next = newNode;  

    return newNode;  
}

Click the File menu, and then click Save All.
