Hello,
I have a visual C# project and i'm trying to insert data in a MS Access Database when i press a button. Here is the code:
private void button1_Click(object sender, EventArgs e)
{
try
{
OleDbDataAdapter adapter=new OleDbDataAdapter();
adapter.InsertCommand = new OleDbCommand();
adapter.InsertCommand.CommandText =
"insert into Candidati values ('" + maskedTextBox1.Text.Trim() + "','" + textBox1.Text.Trim() + "', '" + textBox2.Text.Trim() + "', '" + textBox3.Text.Trim() + "','" + Convert.ToDouble(maskedTextBox2.Text) + "','" + Convert.ToDouble(maskedTextBox3.Text) + "')";
con.Open();
adapter.InsertCommand.Connection = con;
adapter.InsertCommand.ExecuteNonQuery();
con.Close();
MessageBox.Show("Inregistrare adaugata cu succes!");
maskedTextBox1.Text = null;
maskedTextBox2.Text = null;
maskedTextBox3.Text = null;
textBox1.Text = null;
textBox2.Text = null;
textBox3.Text = null;
maskedTextBox1.Focus();
}
catch (AdmitereException exc)
{
MessageBox.Show("A aparut o exceptie: "+exc.Message, "Eroare!", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
The connection string is:
private static string connectionString;
OleDbConnection con;
public AddCandidati()
{
connectionString = "Provider=Microsoft.JET.OLEDB.4.0;Data Source=Admitere.mdb";
con = new OleDbConnection(connectionString);
InitializeComponent();
}
Where AddCandidati is the form.
The data is not saved in the database, why? I have the .mdb file in the project folder.. What i'm doing wrong? I did not got any exception when i press the button..
Thanks!
