A C/C++ application is one of the popular applications used by the business world. It contains various functions and tasks which are performed by the business world. There are many companies that use C/C++ applications for running their business. Now, if you want to change the database structure of the application you have to redesign it. If you don’t want to redesign it then you can use third-party software that will allow you to connect the C/C++ application with a SQL Server database old version.
There are many databases available in the market, but not all of them are compatible with the C/C++ applications. As you might have heard that many C/C++ applications are being used in Windows environments, but now the world has changed a lot because now there are a number of cross-platform application development platforms available in the market. So, here I am going to share with you the best way to connect a C/C++ application to a SQL Server database.
As the name suggests, SQL Server is a database that has been designed to store data. It is very popular among programmers and database administrators because of its flexibility and scalability. The database was developed by Microsoft Corporation and was first introduced in the year 2000. The SQL Server is not only used for storing the data, but it is also used for various other purposes.
C/C++ is a programming language that is used to create applications for the Windows operating system. The C/C++ application is used to manage the data.
There are two ways to connect the C/C++ application to the database:
- SQL Server Native Client (SQNIC)
- SQL Server 2005 ODBC Driver
How to connect a C/C++ application to a SQL Server Database old version?
Steps to follow:
First of all, you have to create a project for the application, in which you can perform all the tasks related to the application. Then, you have to compile the project and run it on the system.
- Create a Project: In this step you have to create a new project and give a name to the project. Open Visual Studio, click on File and then New, then select the project type as Console Application.
- Give a name to the project: After this step, you have to add the code to the project.
Now, you have to add a new class. In this step, you have to add the following code to the class.
#include
using namespace System;
using namespace System::Collections;
using namespace System::Data::SqlClient;
class Database : public List<string^></string^>
{
public:
Database()
{
}
void Add(String^ str)
{
this->Add(str);
}
};
In this step, you have to add the above class as a member of a new class called “Database”. Add the class Database into the main function.
int main()
{
Database^ db = gcnew Database;
db->Add("C++");
return 0;
}
After this step, you have to compile the project. Now, you have to run the project on the system.
- If you are using a 64 bit operating system then you have to change the following path to “C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x64\Microsoft.VC90.CRT\msvcrt.dll”.
- If you are using a 32 bit operating system then you have to change the above path to “C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT\msvcrt.dll”.
Now, you have to run the program on the system. If it shows the error message then you can download the appropriate version of the Microsoft Visual C++ Redistributable package.
In this article, I have discussed the steps to connect a C/C++ application to a SQL Server database old version. You can also use third-party software for this purpose.
