• be sure the button has BS_BITMAP style; you can do this in the resource editor or by calling ModifyStyle.
  
• call ::LoadImage Windows API function to load the bitmap fromthe file
  
• call CButton::SetBitmap
  

BOOL CMyDialog::OnInitDialog()
{
   CDialog::OnInitDialog();
   LoadButtonBitmapImage(IDC_BUTTON3, _T("c:\\mybutton.bmp"));

// ...
}
// NOTE: this is just an example - to be easier to read, no error is handled
void  CMyDialog::LoadButtonBitmapImage(UINT nButtonResID,
                                       LPCTSTR pszBitmapFile)
{
   CButton* pButton = (CButton*)GetDlgItem(nButtonResID);
   // be sure the button has BS_BITMAP style
   pButton->ModifyStyle(BS_ICON, BS_BITMAP);
   // load bitmap from file
   HBITMAP hBitmap = (HBITMAP)::LoadImage(NULL,
                                          pszBitmapFile,
                                          IMAGE_BITMAP, 0, 0,
                                          LR_DEFAULTCOLOR|LR_LOADFROMFILE);
   // set the button bitmap
   pButton->SetBitmap(hBitmap);
}

• somehow you have alread set the BS_OVNERDRAW style for the button? Remove it from resource editor or to be sure anyway change ModifyStyle function like this
  

  pButton->ModifyStyle(BS_ICON|BS_OWNERDRAW, BS_BITMAP);

  
  
• be sure the full-path-and-file-name (pszBitmapFile) is correct. Anyhow, check the returned value of LoadImage. If something goes wrong then it returns NULL:
  

  if(NULL == hBitmap)
  {
     DWORD dwError = GetLastError();
     // use "Error Lookup" tool to see the sescription or call ::FormatMessage.
  }
  

  
  
• be sure IDC_BUTTON1 is indeed the ID of your button control; also verify in resource.h file if you have unique IDs.
