    Probably the combobox is not designed and is not suitable for multiple selections. Consider an alternative: CCheckListBox.

    Hi, @abc abc

    You could try to create CCheckListBox by CListBox:

    1. Drag List Box to the Dialog and modify Has Strings and Owner Draw in properties:

    2. Add CCheckListBox m_CheckListBox; in dialog's .h file.
    3. Add snippet below in dialog's OnInitDialog() function m_CheckListBox.SubclassDlgItem(IDC_LIST1, this);
      m_CheckListBox.SetCheckStyle(BS_AUTOCHECKBOX);
      m_CheckListBox.AddString(L"Test String");
      m_CheckListBox.AddString(L"Test String");
