The HelpText property is typically obtained from tooltip text associated with the element. The property can also be supported with placeholder text appearing in edit or list controls. For example, "Type text here for search" is a good candidate the HelpText property for an edit control that places the text prior to the user’s actual input. However, it is not adequate for the name property of the edit control.
When HelpText is supported, the string must match the application UI language or the operating system default UI language.
The HelpText property has a variant type of VT_BSTR; the default value is NULL.
