In my code, the Shutdown() routine was being called twice by mistake.  I fix it and the crash went away, but I believe you new changes should be done anyway.   Thanks.

loadman: You are very close. I added a few extra bits and pieces so it's basically identical to the C++ dll now. Here is the latest plugin with both C++ and Delphi plugin examples.


--- Code: ---library JukePlugin;

uses
  Dialogs,
  SysUtils,
  Classes;

{$R *.res}

var
PLUGIN_NAME : PChar = 'LCD Display';
PLUGIN_AUTHOR : PChar = 'Loadman';
PLUGIN_VERSION : PChar = 'Beta A';
PLUGIN_DESCRIPTION : PChar = 'This is a plugin';

Buffer: array[0..8192] of Char;

function Juke_Initialize(Value: Integer):Integer; stdcall;
begin
  // Showmessage('DLL has recieved Juke_Shutdown message');
  Result := 1
end;

function Juke_Shutdown(Value: Integer):Integer; stdcall;
begin
  // Showmessage('DLL has recieved Juke_Shutdown message');
  Result := 1
end;

function Juke_GetPluginInfo(Value:integer):PChar; stdcall;
begin
  Result := PChar(PLUGIN_NAME + '|' + PLUGIN_AUTHOR + '|' + PLUGIN_VERSION + '|' + PLUGIN_DESCRIPTION);
end;

function Juke_Command(Name:PChar; Value:PChar):PChar; stdcall;
begin
  StrCopy(Buffer, Value);
  Result := Buffer
end;

exports
  Juke_GetPluginInfo,
  Juke_Initialize,
  Juke_Shutdown,
  Juke_Command;

begin
end.

hehe yeah sorry that should be about it for a while ;) I just wanted to add the corrected Delphi example for loadman. Now he's ready to code his plugin :)

Space Fractal should post a Power Basic plugin example using the new plugin system, then someone should write up some docs and include a list of the common commands and then your just about ready to release the JPS SDK v1.0.

unclet:
I still think the command name and value formats need to be agreed on.

Hey, I really can not stand the "|" character since it is hard to read next to characters like "I", "L" and "1" so how about we use the ">" instead as a separator character like I previously recommended? 

Unless the "|" character is some kind of standard.....
