How do I remove a tooltip currently bound to a control?

Question

I\'m currently adding a tooltip to a label like so:

ToolTip LabelToolTip = new System.Windows.Forms.ToolTip();
LabelToolTip.SetToolTip(this.LocationLabel, te

I modified Gavin Stevens's code to make it all static like so:

class ToolTipHelper
{
    private static readonly Dictionary tooltips = new Dictionary();

    public static ToolTip GetControlToolTip(string controlName)
    {
        
    }
}

Now you no longer have to instantiate a ToolTipHelper (hence it has no need for constructor), and thus you can now access this from any class like so:

ToolTip tt = ToolTipHelper.GetControlToolTip("button1");
tt.SetToolTip(button1, "This is my button1 tooltip");

Also useful with either version is to turn a ToolTip on and off, you can just set tt.Active true or false.

Further improved on this:

class ToolTipHelper
{
    private static readonly Dictionary tooltips = new Dictionary();
    public static ToolTip GetControlToolTip(string controlName)
    {
        
    }
    public static ToolTip GetControlToolTip(Control control)
    {
        return GetControlToolTip(control.Name);
    }
    public static void SetToolTip(Control control, string text)
    {
        ToolTip tt = GetControlToolTip(control);
        tt.SetToolTip(control, text);
    }
}

So now, setting a ToolTip from anywhere in the program is just one line:

ToolTipHelper.SetToolTip(button1, "This is my button1 tooltip");

If you don't need access to the old functions, you could combine them and/or make them private, so the SetToolTip() is the only one you'd ever use.
