Combobox Color Picker 2

This class, CColorComboEx, is a combobox that instead of displaying strings, displays the standard colors much like the one in Developer Studio. It also has support for the "Automatic" color option. To add a color combobox to your project, first add the ColorComboEx.h and ColorComboEx.cpp files into your project. Next, in the resource editor, add a combobox. Make sure that the combobox has the "Drop List" type, the "Fixed" owner draw type, and the "Has Strings" checkbox checked. Now using ClassWizard, add a member variable for the control based on the CColorComboEx class. Just compile and run, and you will have a color combobox.

  • Using the CColorComboEx example...

    Hey there!

    I needed a combo box to let the user choose a color. Fortunately Codeguru provides an example in combo box section! But then I had a problem...

    As a test I inserted a normal combo box to a dialog ressource and created a control variable (CComboBox m_cTest). Of course it worked.

    Then I replaced CComboBox by CColorComboEx in the header file just for a test. It worked too. Fine!

    In my program I have to create the color box at runtime. First I tried it with a normal combo box. No probs! Then with the CColorComboEx:

    Header -

    CColorComboEx* m_pcTest;

    Source -

    BOOL CMyDialog::OnInitDialog()
    {
    CDialog::OnInitDialog();
    CRect ItemRect(10,10,100,50);

    m_pcTest = new CColorComboEx();
    m_pcTest->Create(WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_TABSTOP | CBS_DROPDOWNLIST | CBS_OWNERDRAWFIXED | CBS_SORT | CBS_HASSTRINGS, ItemRect,this,IDC_COMBOTEST);
    return TRUE;
    }

    Result: Assertion error in winctrl1.cpp, line 186

    I got the same result for a normal combo box with the CBS_OWNERDRAWFIXED style!!!

    Why can I use CBS_OWNERDRAWFIXED in the resource editor but not when I have to create the control manually? Is anything wrong with the styles???

    I have no idea!

    Is anybody out there who can help me?

    Thanks in advance

    combo boxes work.
