Re: unable to display check/radio box with transparent background

Try this: (Note: Not sure if it will work for PocketPC)

#pragma once

// CTransparentCheckBox

class CTransparentCheckBox : public CButton
{
 DECLARE_DYNAMIC(CTransparentCheckBox)

public:
 CTransparentCheckBox();
 virtual ~CTransparentCheckBox();

protected:
 DECLARE_MESSAGE_MAP()
public:
   afx_msg HBRUSH CtlColor(CDC* /*pDC*/, UINT /*nCtlColor*/);
   afx_msg BOOL OnEraseBkgnd(CDC* pDC);
};

// TransparentCheckBox1.cpp : implementation file
//

#include "stdafx.h"
#include "TransparentCheckbox1.h"

// CTransparentCheckBox

IMPLEMENT_DYNAMIC(CTransparentCheckBox, CButton)
CTransparentCheckBox::CTransparentCheckBox()
{
}

CTransparentCheckBox::~CTransparentCheckBox()
{
}

BEGIN_MESSAGE_MAP(CTransparentCheckBox, CButton)
   ON_WM_CTLCOLOR_REFLECT()
   ON_WM_ERASEBKGND()
END_MESSAGE_MAP()

// CTransparentCheckBox message handlers

HBRUSH CTransparentCheckBox::CtlColor(CDC* pDC, UINT /*nCtlColor*/)
{
   pDC->SetBkMode(TRANSPARENT);
   return (HBRUSH)GetStockObject(HOLLOW_BRUSH);
}

BOOL CTransparentCheckBox::OnEraseBkgnd(CDC* pDC)
{
   return TRUE;
}
