Delphi XE2 Cannot get BPL plugin work -

-

i tried implement simple module system xe2 couldn't work. when try run under ide, can handle loadpackage() cannot class getclass() (even though registerclass()ed within initialization section of bpl). when try run under windows, "this application has failed start because rtl160.bpl not found" error, , cannot load package.

module code

type   tfrmodule = class(tframe)     button1: tbutton;     procedure button1click(sender: tobject);   private     { private declarations }   public     { public declarations }   end;  implementation  {$r *.dfm}  procedure tfrmodule.button1click(sender: tobject); begin   showmessage('hello'); end;  initialization   registerclass(tfrmodule);   showmessage('registered');  finalization   unregisterclass(tfrmodule);   showmessage('unregistered');

also, initialization section not being executed because see no 'registered' message box.

and host app this;

var   hmod: hmodule;   fcmod: tpersistentclass;   frmod: tframe;  procedure tform4.button1click(sender: tobject); begin   hmod := loadpackage('module.bpl');   if (hmod = 0) exit;    fcmod := getclass('tfrmodule');   if assigned(fcmod)   begin     frmod := tframe(fcmod.create);     frmod.parent := panel1;   end; end;

host app linked runtime packages true. module doesn't have runtime packages option.

another question. saw basic example on net plan add more similar modules , what's going happen if try registerclass() second module's tfrmodule class in initialization? if need give different name each module, there's no point of modules anyway. mean, if host must know module's classes like.

everything works fine here. host app uses runtime packages vcl , rtl. module requires rtl , vcl packages. these packages have deployed. see 'registered' message box , getclass function succesfully called ...

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
