I need help with sending strings to a ListBox

  • I'm programming with DEV C++.
    I creatred one form with 3 listboxes, but only on the first I can add items (rwos), the others two seems to be active but not managed by the program.

    To create the listboxes I worte, under the WM_CREATE:

    hWndListBox1 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
    30, 30, 200, 800, hwnd, (HMENU)IDC_LISTBOX_TEXT1, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
    if (!hwnd)
    MessageBox(NULL, "ListBox 1 Failed.", "Error", MB_OK | MB_ICONERROR);
    SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT1, WM_SETFONT, (WPARAM)hFont_list, TRUE);

    hWndListBox2 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
    330, 400, 200, 418, hwnd, (HMENU)IDC_LISTBOX_TEXT2, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
    if (!hwnd)
    MessageBox(NULL, "ListBox 2 Failed.", "Error", MB_OK | MB_ICONERROR);
    SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT2, WM_SETFONT, (WPARAM)hFont_list, TRUE);

    hWndListBox3 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
    600, 400, 200, 418, hwnd, (HMENU)IDC_LISTBOX_TEXT3, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
    if (!hwnd)
    MessageBox(NULL, "ListBox 3 Failed.", "Error", MB_OK | MB_ICONERROR);
    SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT3, WM_SETFONT, (WPARAM)hFont_list, TRUE);

    The first listbox runs with the call:
    SendMessage(GetDlgItem(hwnd, IDC_LISTBOX_TEXT1), LB_ADDSTRING, 0, (LPARAM)Testo_Val1);

    To add items on the listbox 2 I use:
    SendMessage(GetDlgItem(hWndListBox2, IDC_LISTBOX_TEXT2), LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

    but on the listbox 3 I tried with:
    SendMessage(hWndListBox2, LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

    I also tied with:
    SendMessage(GetDlgItem(hwnd, IDC_LISTBOX_TEXT3), LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

    but without any result.

    I can't understand why the listboxes 2 and 3 aren't managed.

    NOTE:

    char Testo_Val1[25];
    char Testo_Val2[25];
    char Testo_Val3[25];

    Thanks in advance for any help!!!
