But when i am clicking on button, it doesn't work. i am using this code.

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));
    }
}

How can you create the form and manage at runtime?

The proper method to create dynamic forms at runtime is to add controls to and remove them from your form as needed, using the techniques discussed in this section. Just as you can create new instances of forms, you can also create new instances of any control and place them on a form.

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.

Updating the CultureInfo at runtime might reset component size. This code preserves the size and position of the controls (there will still be visible flickering though, which using SuspendLayout() couldn't fix)


    private void langItem_DropDownItemClicked(object sender, ToolStripItemClickedEventArgs e)
    {
        //I store the language codes in the Tag field of list items
        var itemClicked = e.ClickedItem;
        string culture = itemClicked.Tag.ToString().ToLower();

        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(culture);
        ApplyResourceToControl(
        this,
        new ComponentResourceManager(typeof(GUI)),
        new CultureInfo(culture));           
    }

    private void ApplyResourceToControl(
       Control control,
       ComponentResourceManager cmp,
       CultureInfo cultureInfo)
    {
        foreach (Control child in control.Controls)
        {
            //Store current position and size of the control
            var childSize = child.Size;
            var childLoc = child.Location;
            //Apply CultureInfo to child control
            ApplyResourceToControl(child, cmp, cultureInfo);
            //Restore position and size
            child.Location = childLoc;
            child.Size = childSize;
        }
        //Do the same with the parent control
        var parentSize = control.Size;
        var parentLoc = control.Location;
        cmp.ApplyResources(control, control.Name, cultureInfo);
        control.Location = parentLoc;
        control.Size = parentSize;
    }
