Very interesting - but all this occurs way to quickly and without allowing us to investigate the your actual code - which particuarly as we are not natively Delphi Dev's is problematic.

Please supply a simplified project with a full set of your Delphi source files - zipped) and with NO license info and we will try and assist.

Without these there is little we can do.

Also please advise which build of our products you are using (version info)

Hi John
problem is

Delphi 7 sample definition is:
procedure TForm1.CoPDFXCview1Event(ASender: TObject; Type_: Integer;
const Name: WideString; const DataIn: OleVariant; out DataOut: OleVariant;
Flags: Integer);

Delphi 2007 and 2009
procedure TForm1.CoPDFXCview2Event(ASender: TObject; Type_: Integer;
const Name: WideString; DataIn: OleVariant; out DataOut: OleVariant;
Flags: Integer);

Hello Miro,

Just to confirm - the text in red in your above post is the cause of the problems and we shall consider this as solved right?

Best,
Stefan

Hi Stefan,
yes
Delphi 2007 and 2009 generates event method without "const" for DataIn parameter.
The method causes crash.

Just add "const" before DataIn parameter then method works OK.
