How to use it:

 The
steps for usage are as follows:


1.
Add code in those head files
where you want to display Color Picker Dialog.

#include "FODropColorButton.h"

enum { IDD = IDD_DIALOG_COLORPICKER };
CFODropColorButton m_wndColor3;
CFODropColorButton m_wndColor2;
CFODropColorButton m_wndColor1;
CFOHyperLink m_newVersion;
//}}AFX_DATA


2.
Add code in those files/events
when you need to get color value.

CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CNewPickerDlg)
DDX_Control(pDX, IDC_FO_TEST_BUTTON3, m_wndColor3);
DDX_Control(pDX, IDC_FO_TEST_BUTTON2, m_wndColor2);
DDX_Control(pDX, IDC_FO_TEST_BUTTON1, m_wndColor1);
//}}AFX_DATA_MAP
DDX_FODropColorButton(pDX,IDC_FO_TEST_BUTTON1,crColor1);
DDX_FODropColorButton(pDX,IDC_FO_TEST_BUTTON2,crColor2);
