MFC ComboBox dropdown list too short

Question

I have dropped ComboBox on dialog form. Also I have added some text to it:

BOOL CMyAppDlg::OnInitDialog()
{

    CComboBox *combo= (CComboBox *)GetDlgItem(IDC_COMBO_TT);
    combo->AddString("s1");
    combo->AddString("s2");

//...
return TRUE;
}

When I drop down ComboBox it shows only one selection line and adds arrows to select other items. How to increase dropdown size?

You are the same person who asked [this question](http://stackoverflow.com/questions/23738212/add-strings-to-mfc-combobox), with *the exact same code*. Why have you posted a new question, instead of editing the original? — Cody Gray - on strike, May 19 '14 at 13:35

I have done two apps with the same code. One app DDList shows nothing while other shows one position. That is why code is the same. Now I see the problem — vico, May 19 '14 at 13:42

Click the combo button in dialog editor. You can now drag down to set the open size.
