Visionneuse PDF avec dynawrap

bonjour,

pour tester la version am=E9lior=E9e du composant dynawrap
(la version initiale datait de 1998) =E9crit par Gilles Laurent:
http://glsft.free.fr/index.php?option=3Dcom_content&task=3Dview&id=3D47&Ite=
mid=3D33
j'ai imagin=E9 une visionneuse pdf basique qui utilise les services du
freeware
sorax reader dispo ici: http://www.soraxsoft.com/index.html

il convient d'y ajouter une petite dll =E9crite par mes soins dispo ici:
http://rapidshare.com/files/133592229/PdfScript.dll.html

je dois dire que je n'ai pas tr=E8s bien compris la syntaxe
de la fonction SetMemInBSTRAddr avec nDataType=3Ddw_BSTR
mais =E7a n'a pas d'incidence sur le bon fonctionnement du code...

ps: la gestion des bookmarks n'a pas =E9t=E9 achev=E9e ;-)
