Follow the Video Tutorial here
Follow the below mentioned Steps
(2) Add the reference of DBcon.dll in your Project
(i) Right click on project in Solution Explorer -> Add Reference
(ii) Go to Browse Tab->select DBcon.dll you have downloaded->click OK
(3) Start Doing Database Connection
- using DBCon ; //include this namespace in forms
- Initialize Connection, you need to do this only once in your application
DBConClass dc;// create this obect in your form class
Go to Load event of First form in your application
private void Form1_Load(object sender, EventArgs e)
{
//Establishing Connection
//This is one time Process in Entire Project . You need to do this only
//one time in your project
dc = new DBConClass();
dc.setSQLConnection(".", "test", "sa", "sql");
}
private void button1_Click(object sender, EventArgs e)
{
//Here after Whenever you need database operation Only need to do as follows
string query = "Insert into Student values("+txtRoll.Text+",'"+txtName.Text+"')";
dc = new DBConClass();
int res = dc.ExecNonQuery(query);
{
//Here after Whenever you need database operation Only need to do as follows
string query = "Insert into Student values("+txtRoll.Text+",'"+txtName.Text+"')";
dc = new DBConClass();
int res = dc.ExecNonQuery(query);
}
5.Fetch data in Form 2
DBConClass dcon;
private void button1_Click(object sender, EventArgs e)
{
string query = "Select * From Student";
dcon = new DBConClass();
dcon.ExecuteQuery(query);
try
{
dataGridView1.DataSource = dcon.dtable;
}
catch
{
}
}
{
string query = "Select * From Student";
dcon = new DBConClass();
dcon.ExecuteQuery(query);
try
{
dataGridView1.DataSource = dcon.dtable;
}
catch
{
}
}
