Can someone tell me whats wrong with this:
Code:
case ID_GETLIST:
{
char *ListSel;
PSTR ListStr;
int x;
x = SendMessage(list,LB_GETTEXTLEN,0,0);
ListStr = (PSTR) VirtualAlloc((LPVOID) NULL,
(DWORD) (x + 1), MEM_COMMIT,
PAGE_READWRITE);
SendMessage(list,LB_GETTEXT,0,ListStr);
//GetWindowText(edit, ListStr,x + 1);
ListSel = ListStr;
SetWindowText(edit,ListSel);
}
