[Paradox] Insertion d'une Image

Bonjour,

Je cherche à insérer une image dans une base de données paradox.
Le truc c'est que j'utilise les requêtes SQL, donc ce que j'ai composants c'est un TDataSource et un TQuery, je charge le nom de l'image dans un Edit et maintenant je cherche comment construire ma requête pour mettre l'image dedans.
Est-ce que je dois charger l'image dans une dbimage pour pouvoir le faire? ou est-ce que le chemin vers cette image peut suffir? Comment faire?

Merci d'avance :)

Salut

Tu auras beaucoup d'images à stocker ?
Parce que ce n'est pas forcément une bonne idée. Ta table PDX va très vite prendre de l'ampleur. :aie:

Je verrais plus stocker le chemin d'accès vers ton image, et la charger dans un simple TImage.

Ben le prof a demandé ca :/
Au départ j'avais pensé à faire comme ca aussi..
Bon je vais plutôt stocker le nom de l'image alors. Mais comme mon application devrait se lancer sur n'importe quelle machine, je voudrais avoir une meilleure gestion des répertoires, genre comment récupérer le chemin complet vers le mon application ?

Tu peux obtenir cette information avec Application.ExeName ou directement avec ParamStr(0).

Merci beaucoup je vais faire ainsi :)

Voici ci-après une architecture pour visualiser 4 images 3 *.bmp + 1 *.jpg à partir d'une librairie..
