Kan man på något enkelt sätt inifår programmet kolla hur mycket minne projektet använder?

Patrik

Om du kompilerar och gör en exefil, sedan startar projektet så kan du via aktivitetshanteraren se hur mycket minne din exefil tar.

Jo, det vet jag om men jag tänkte använda värdet inne i programmet

/Patrik

Hittade info om systemets minne men inte programmet. Tror dock att det finns något API som kan ta reda på detta genom att först kalla på vilken process man är och därefter fånga minnesåtgången.
