ToolTip property
Use the ToolTip property to specify text to be displayed as a "tool tip" for a component.
A tool tip is a short line of text displayed when the mouse pointer moves over a component.
The ToolTip property accepts substitution keywords as values for component tool tips. When a form is opened, the keywords are processed by the internal string substitution method, enabling the dynamic tooltip content that contains statements and the applicable keywords.
The substitution method processes the keywords when the form opens, that enables the dynamic tool tip content that includes statements with the applicable substitution keywords.
Text can consist of alphanumeric characters only, with no tabs or hard returns. The maximum length is 256 characters.
