How to show form in front in C#

Question

Folks,

Please does anyone know how to show a Form from an otherwise invisible application, and have it get the focus (i.e. appear on top of other windows)?

Answer 1

This is the final solution I wrote after 20 different attempts:

/* A workaround for showing a form on the foreground and with focus,
 * even if it is run by a process other than the main one
 */
public static void ShowInForeground(this Form form, bool showDialog = false)
{
    if (showDialog)
    {
        //it's an hack, thanks to http://stackoverflow.com/a/1463479/505893
        form.WindowState = FormWindowState.Minimized;
        form.Shown += delegate(Object sender, EventArgs e) {
            ((Form)sender).WindowState = FormWindowState.Normal;
        };
        form.ShowDialog();
    }
    else
    {
        //it's an hack, thanks to http://stackoverflow.com/a/11941579/505893
        form.WindowState = FormWindowState.Minimized;
        form.Show();
        form.WindowState = FormWindowState.Normal;

        //set focus on the first control
        form.SelectNextControl(form.ActiveControl, true, true, true, true);
    }
}
