Thanks all guys. I was thinking about this, but i would not be sure. I have programmed in VBA for about 3 years and before that about 4 years in Delphi.
when i want something done in Delphi, i first create a macro in VBA to know how i should do it in Delphi. Of course, when i program in VBA i do not create Macro's :) When creating the macro, VBA tells me that i need to use 1.5 for setting my bottom margin. That Delhi sees this as 1.5 points, that was unclear to me. Thanks for pointing this out to me guys.
