I have a TDBEdit that is not enabled and thus not showing the Hint.
What would be the best way to have it display the Hint while staying disabled?

Answer Snippets (Read the full thread at stackoverflow):
Drop your disabled TWinControl (TDBEdit is a TWinControl) onto an enabled TWinControl container (a TPanel for example) and set the TPanel hint.
ShowHint set to True and a Hint property set.

Say I have a table in a SQL 2005 database with 2,000,000+ records and a few indexes. What advantage is there to using index hints in my queries? Are there ever disadvantages to using index hints in queries?

In that case you provide the index hint telling the database engine which index to use.
The index hint will only come into play where.

I want a TPageControl and some TTabSheets, with 'per tabsheet' tooltip hints visible as I hover over each tab in turn.
Is there any way of getting this effect in Delphi 2009?

I am not sure how to make it change the hint based tab the mouse is hovering over.

Best I can think of is to surround the subject of the hint with a conditional define, and use will get: Hint: variable "i" is declared but never used
So try this instead:
procedure MyProc never get a hint.
