Description
1. How can i read the width and height of the scroll bars of a DBGrid?

2. When a field is empty (contains NULL), its "value" do not show in DBGrid (empty). How can i set NULL fields to zero in a complex SQL query, like:

SELECT Name AS Csapat, M, GY, (M-GY-V)*(:Draw) AS D, V, LG, KG, GY*(:Win)+(M-GY-V)*(:Draw) AS P
FROM "m.sql" FULL OUTER JOIN TmpTeam ON "m.sql".IDTeam=TmpTeam.IDTeam
FULL OUTER JOIN "lg.sql" ON "lg.sql".IDTeam=TmpTeam.IDTeam
FULL OUTER JOIN "kg.sql" ON "kg.sql".IDTeam=TmpTeam.IDTeam
FULL OUTER JOIN "ny.sql" ON "ny.sql".IDTeam=TmpTeam.IDTeam
FULL OUTER JOIN "v.sql" ON "v.sql".IDTeam=TmpTeam.IDTeam
ORDER BY P DESC, KG ASC

3. How can i remove the vertical scroll bar from a DBGrid without any flash when i press up or down cursor keys?
