Hallo Leute!
Ich bin neu hier und hab ein mehr oder weniger großes Problem.
Ich hab ein Remote Administration Tool für meinen Server geschrieben, die Funktionen sind folgende:
- Server ausschalten
- Laufwerke auflisten
- Bildschirm "sperren"(ist einfach eine 2. Form wo auf schwarzem Hintergrund ein Text steht)
- Ordner Auflisten
- Beliebige Daten downloaden
Mein Problem ist nun, dass dieses Programm viel zu viel Arbeitsspeicher verbraucht, und ich diesen geren für meinen Server zur Verfügung haben möchte.
Ich post gleich mal meinen Code hier unten mit dazu, damit ihr euch das ganze leichter anschauen könnt :)

Zu viel Arbeitsspeicherverbrauch
