Use the cToolTipTextSourceProperty property of the control to specify a different source for the tooltip texts. For example, set it to "StatusBarText" if you want to use the StatusBarText value as tooltip text. You can also use your own property, etc. If the specified property does not exist for a control or it is empty, the default ToolTipText value is used. This allows you to have tooltips as long as you want! No more limitations to 52, 127, 256, etc!

Thanks to Petras Virzintas for this idea.
