Poblème avec un pointeur...

Bonsoir,

J'essaye tant bien que mal de mettre en place une ListView...Le seul problème est malheureusement cette ligne de code...je n'arrive pas a savoir d'ou vient l'erreur...

wpOrigEditProc = (PVOID)SetWindowLong(hEdit, GWL_WNDPROC, (LONG)EditProc);

 invalid conversion from `void*' to `LRESULT (*)(HWND__*, UINT, WPARAM, LPARAM)'

Tout conseils sont les bien-venus...

Voici le code complet.....
