Constante et énumération LVITEM dans API SendMessage

Question

Bonjour
Dans la déclaration ci-dessous de l'API SendMessage employée avec une ListView, à quelle constante correspond Int32 wMsg?
static extern Int32 SendMessageA (Int32 hwnd, Int32 wMsg, Int32 wParam, LVITEM pitem); 
Le contexte: saisie d'e lettre(s) dans une TextBox et sélection par l4API de l'item correspondant dans la ListBox.
Par ailleurs, dans l'énumération LVITEM, il y a mask qui, je crois, permet de définir le subitem objet de la recherche. Comment s'en sert-on?. 
Merci.

Pour le LVITEM :

Ex :

lvItem.mask=LVIF_TEXT|LVIF_IMAGE|LVIF_PARAM;

List Const :

Public Const LVIF_TEXT = &H1
Public Const LVIF_IMAGE = &H2
Public Const LVIF_PARAM = &H4
Public Const LVIF_STATE = &H8
Public Const LVIF_INDENT = &H10           'IE 3+ only
Public Const LVIF_NORECOMPUTE = &H800     'IE 3+ only
Public Const LVIF_DI_SETITEM = &H1000

CA te permet de definir les champs valide dans le domaine d'application.

Si tu veux faire une recherche tu dois utiliser la methode getITem avec un lvitem du style :

lvi.iItem = nItemIndex;
lvi.iSubItem = 0;
lvi.mask = LVIF_TEXT;
lvi.pszText = szBuffer;
lvi.cchTextMax = cchBuf;
cListCtrl.GetItem(adresseof(lvi));

Merci pour ta réponse.
Les outils sont bien là :) ...
... mais le mode d'emploi me manque  ;) .
J'ai essayé d'arriver à faire quelque chose, mais les erreurs pleuvent de partout, à tel point que je ne sais plus du tout ce qu'il en est.
