Rich Edit Alignment

Code:

case ID_ALIGN_LEFT:
                {


                    HWND Active = (HWND)SendMessage(MDIClient, WM_MDIGETACTIVE, NULL, NULL);
                    if(Active == NULL)
                    {
                        PARAFORMAT pf;
                        pf.cbSize = sizeof(PARAFORMAT);
                        pf.dwMask = PFM_ALIGNMENT;
                        pf.wAlignment = PFA_LEFT;

                        SendMessage(GetDlgItem(Active, CHILD_EDIT), EM_SETPARAFORMAT, NULL, (LPARAM)&pf);
                    }
                }
                break;

is what I have for setting the alignment to left.

This is a MDI program, first I get the active window, then I make a PARAFORMAT structure (this is where i think im doing something wrong). Then i send the message to the Rich Edit control.

Thanks.
