Smiley (image dans un RichEdit)

Salut à tous !
Je developpe un chat et je voudrais integrer des smiley.
Le probleme c'est que je ne sais pas comment insérer une image dans un memo ou un richedit. Quelcun pourrait m'aider ?
Merci a tous.
Nicolas

Pour le memo, je pense pas que ce soit possible. Vu que c'est un fichier texte (txt) et qui n'y a pas d'image dans ce type de fichier.
Pour les RichEdit, on en a déjà parlé.

Sinon, j'ai trouvé ca (pas testé :oops: ) :

Voici un composant Richedit qui supporte des images :
