Open form button:
frmCatalogos formulario = new frmCatalogos();
this.Hide();
formulario.ShowDialog();
this.Show();
All right up there.
The problem arises when I click on a button in the following form.
performs all the complete tour and then returns to this.Show(); as this may be because if you see the operation I intend only to create a single instance of form.
To have only 1 instance of the form, you should do something like this:
public partial class Form1 : Form
{
private Form2 formulario;//Declarar aqui la variable del formulario
public Form1()
{
InitializeComponent();
this.formulario = new Form2();//Inicializarlo una sola vez
}
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
this.formulario.ShowDialog();//Llamarlo de este modo, sin poner el New
this.Show();
}
}
