This document contains C# code for inserting buttons that perform database operations. It defines a form class with buttons for searching, inserting, updating, and deleting data from a Microsoft Access database table called "Tabla1". The buttons use OleDb to connect to the database, build SQL queries, execute them, and handle the results. Searching populates text boxes and a data grid. Inserting, updating, and deleting execute SQL commands and show success messages.
![OleDbCommandBuilder cb = new OleDbCommandBuilder(da);
DataTable dt = new DataTable();
da.Fill(dt);
int fila1 = 0;
if (dt.Rows.Count > 0)
{
DataRow dr = dt.Rows[fila1];
textNombre.Text = dr["vNombre"].ToString();
OleDbDataAdapter da2 = new OleDbDataAdapter("select * from Tabla1", conexion);
OleDbCommandBuilder cb2 = new OleDbCommandBuilder(da2);
//DataTable dt2 = new DataTable();
DataSet dsDatos = new DataSet();
da2.Fill(dsDatos, "Vendedores");
this.dataGridView1.DataMember = "Vendedores";
this.dataGridView1.DataSource = dsDatos;
}
else

textNombre.Text = "";
MessageBox.Show("No hay datos");
}
