Access Violation on Application Close

1. offizieller Beitrag

    Hi

    This problem cause only on registered version!!! (It was ok on DEMO)

    It is the only code:

    Code
    procedure TForm1.Button1Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
    if OpenDialog1.FileName<>'' then WPViewPDF1.filename:=OpenDialog1.FileName;
end;

    http://www.zuzlan.name/pdf-error.zip - test exe + wPDFView03.dll

    Program work fine until i'm trying close my app.

    Should i do some uninitialize or something?
    (D7, win XP)

    I have fix it by myself:

    Code
    procedure TForm1.FormCreate(Sender: TObject);begin  WPViewPDFDLLHandle:=0;end;

    Queerly, because it present on initializing section of WPViewPDF3.pas

    Code
    initialization


WPViewPDFDLLHandle := 0;
