Re: Using HBITMAP with CBitmpa/CBitmapButton

Here is a CBitmapButton dervied class that loads bitmaps from bitmap files
instead of resource

#pragma once

// CBitmapButtonEx

class CBitmapButtonEx : public CBitmapButton
{
   DECLARE_DYNAMIC(CBitmapButtonEx)

public:
   CBitmapButtonEx();
   virtual ~CBitmapButtonEx();

   BOOL LoadBitmapsFromFile(LPCTSTR lpszBitmapResource,LPCTSTR
lpszBitmapResourceSel = NULL,LPCTSTR lpszBitmapResourceFocus = NULL,LPCTSTR
lpszBitmapResourceDisabled = NULL );

protected:
   DECLARE_MESSAGE_MAP()
};

// BitmapButtonEx.cpp : implementation file
//

#include "stdafx.h"
#include "BitmapButton.h"
#include "BitmapButtonEx.h"

// CBitmapButtonEx

IMPLEMENT_DYNAMIC(CBitmapButtonEx, CBitmapButton)
CBitmapButtonEx::CBitmapButtonEx()
{
}

CBitmapButtonEx::~CBitmapButtonEx()
{
}

BEGIN_MESSAGE_MAP(CBitmapButtonEx, CBitmapButton)
END_MESSAGE_MAP()

// CBitmapButtonEx message handlers
BOOL CBitmapButtonEx::LoadBitmapsFromFile(LPCTSTR lpszBitmap,LPCTSTR
lpszBitmapSel,LPCTSTR lpszBitmapFocus,LPCTSTR lpszBitmapDisabled)
{
   HANDLE hBmp =
LoadImage(NULL,lpszBitmap,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
   if (hBmp == NULL)
   {
      return FALSE;
   }

   m_bitmap.Attach(hBmp);

   BOOL AllLoaded = TRUE;
   if (lpszBitmapSel != NULL)
   {
      hBmp =
LoadImage(NULL,lpszBitmap,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
      if (hBmp != NULL)
      {
       m_bitmapSel.Attach(hBmp);
      }
      else
      {
         AllLoaded = FALSE;
      }
   }
   if (lpszBitmapDisabled != NULL)
   {
      hBmp =
LoadImage(NULL,lpszBitmapDisabled,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
      if (hBmp != NULL)
      {
       m_bitmapDisabled.Attach(hBmp);
      }
      else
      {

   return AllLoaded;
}
