Re: Out of Memory

  Alt 3. Aug 2007, 10:08
So, ich hab wie gesagt mal laufen lassen, der Fehler ist wie erwartet nochmal aufgetreten.
Zur allgemeinen Info, ich lese aus Outlook Mails aus, ziehe gezielt Informationen heraus und speichere diese ab.
Zurzeit ist eine Mail ein Datensatz. Später werden aber immer 2 Mails zusammengehären, welche an unterschiedlichen Orten liegen und ich weiß zu Beginn nicht, wo, was später eine Schwierigkeit darstellt wegen OutOfMemory.

Der Quelltext: (Delphi 7)
€: Die wichtigsten Prozeduren sind die, die weiter unten stehen...
€2: musste noch ein paar Zensuren vornehmen
Delphi-Quellcode:
// Datensatz

TDataSetLic1 = record
  PurchaseOption : string;
  TypeOfPlatform : string;
  TypeOf_License : string;
  Clients_name : string;

  Contact_person : string;
  Clients_email : string;
  Clients_phone : string;
  Expiration : string;
  Price : string;
  server : string;
  note : string;

  license_user : string;
  license_pass : string;

  folder : string;
  art : string;
  subject : string;
  from : string;
end;

TMail = record
  body : string;
  from : string;
  subject : string;
  folder : string;
  time: string;
end;


var
  Form1: TForm1;
  // für Outlook-Zugriff
  Outlook: _Application; // OutlookApplication; for D5 users
  NmSpace: NameSpace;
  //der aktuelle Order in Outlook
  Folder: MAPIFolder;

  // keine großen Arrays, max. 20 Felder
  folderStrings: array of string;
  forbiddenFolders: array of string;

  // großes Array, bisher liegen hier all Datensätze
  licenseSet1: array of TDataSetLic1;

  //Unwichtig
  testbereich: boolean;

  // Für die Statistik
  start_global_timer: boolean;
  st_timerAll, st_counterAll : integer;
