How do I set the size of the visible area of a form, minus heading and borders?

Question

I would like to set my form to be exactly 300*300 excluding heading and borders.

If I use Size property, it does include these values.

Is there any way how t

There is workaround to set proper Size by designer tool: 1. Set FormBorderSize to "None". 2. Set prefered Size (e.g. "300; 300"). 3. Set FormBorderSize to prefered border (additional needed space will be added to Size property automaticly).
