private void btnfrench_Click(object sender, EventArgs e)
{
    getlanguage("fr-FR");
}

private void getlanguage(string lan)

    foreach (Control c in this.Controls)
    {
        ComponentResourceManager cmp = 
            new ComponentResourceManager(typeof(BanksForm));
        cmp.ApplyResources(c, c.Name, new CultureInfo(lan));
    }
}

This worked:

private void button1_Click(object sender, EventArgs e)
{
    System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("fr-BE");
    ComponentResourceManager resources = new ComponentResourceManager(typeof(Form1));
    resources.ApplyResources(this, "$this");
    applyResources(resources, this.Controls);
}

private void applyResources(ComponentResourceManager resources, Control.ControlCollection ctls)
{
    foreach (Control ctl in ctls)
    {
        resources.ApplyResources(ctl, ctl.Name);
        applyResources(resources, ctl.Controls);
    }
}

Be careful to avoid adding whistles like this that nobody will ever use. It at best is a demo feature, in practice users don't change their native language on-the-fly.
