What is the best way to store the font for a TDBGrid. I can change it fine with a 
Font Dialog but how can i store those settings so they take effect the next time 
the user fires up the program ?

Answer:

Save a font:


1   function SaveFont(F_Font: TFont): boolean;
2   var
3     FLog: TLogFont;
4     Reggy: TRegistry;
5   begin
6     GetObject(F_Font.Handle, SizeOf(FLog), @FLog);
7     Reggy := TRegistry.Create;
8     try
9       Reggy.OpenKey({'\REGKEYNAME'}, true);
10      Reggy.WriteBinaryData({'VALUENAME'}, FLog, SizeOf(FLog));
11      result := true;
12    finally
13      Reggy.Free;
14    end;
15  end;
16  
17  
18  //Get a font:
19  
20  
21  function SetFont(F_Font: TFont): boolean;
22  var
23    FLog: TLogFont;
24    Reggy: TRegistry;
25    NewFHnd: longint;
26  begin
27    result := false;
28    Reggy := TRegistry.Create;
29    try
30      if Reggy.OpenKey({'\REGKEYNAME'}, false) and
31        Reggy.ValueExists({'VALUENAME'}) then
32      begin
33        Reggy.ReadBinaryData({'VALUENAME'}, FLog, SizeOf(FLog));
34        {set Font to the retrieved font}
35        NewFHnd := CreateFontIndirect(FLog);
36        result := (NewFHnd <> 0);
37        if result then
38          F_Font.Handle := NewFHnd;
39      end;
40    finally
41      Reggy.Free;
42    end;
43  end;
