This answer will help in case, If you are working with Data Bases then mostly take the help of try-catch block statement, which will help and guide you with your code. Here i am showing you that how to insert some values in Data Base with a Button Click Event.
private void button2_Click(object sender, EventArgs e)
{
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" +
@"Data source= C:\Users\pir fahim shah\Documents\TravelAgency.accdb";
try
{
conn.Open();
String ticketno=textBox1.Text.ToString();
String Purchaseprice=textBox2.Text.ToString();
String sellprice=textBox3.Text.ToString();
String my_querry = "INSERT INTO Table1(TicketNo,Sellprice,Purchaseprice)VALUES('"+ticketno+"','"+sellprice+"','"+Purchaseprice+"')";
OleDbCommand cmd = new OleDbCommand(my_querry, conn);
cmd.ExecuteNonQuery();
MessageBox.Show("Data saved successfuly...!");
}
catch (Exception ex)
{
MessageBox.Show("Failed due to"+ex.Message);
}
finally
{
conn.Close();
}
