Codejock Developer Community : Drawing problem

CBitmap bmpSrc;

bmpSrc.Attach( hBitmap );

item.pPopupBitmap->Attach( CXTPImageManager::Create32BPPDIBSection( 0, m_nPopupWidth, m_nPopupHeight + m_nCaptionHeight ) );

CXTPCompatibleDC dcSrc( 0, &bmpSrc );

CXTPCompatibleDC *pdcDest = new CXTPCompatibleDC( 0, item.pPopupBitmap );

BITMAP bmpInfo;

ZeroMemory( &bmpInfo, sizeof( BITMAP ) );

bmpSrc.GetBitmap( &bmpInfo );

int nWidth = bmpInfo.bmWidth;

int nHeight = bmpInfo.bmHeight;

if ( nWidth > m_nPopupWidth )

{

float fAspectRatio = (float)nWidth / (float)m_nPopupWidth;

nWidth = m_nPopupWidth;

nHeight = (int)( ( (float)nHeight / fAspectRatio ) + 0.5f );

}

if ( nHeight > m_nPopupHeight )

{

float fAspectRatio = (float)nHeight / (float)m_nPopupHeight;

nHeight = m_nPopupHeight;

nWidth = (int)( ( (float)nWidth / fAspectRatio ) + 0.5f );

}

int nX = ( m_nPopupWidth - nWidth ) / 2;

int nY = ( m_nPopupHeight - nHeight ) / 2;

// clear thumbnail

pdcDest->FillSolidRect( 0, 0, m_nPopupWidth, m_nPopupHeight, RGB( 252, 252, 252 ) );

// draw thumbnail

// delete pdcDest;

// pdcDest = new CXTPCompatibleDC( NULL, item.pPopupBitmap );

pdcDest->SetStretchBltMode( HALFTONE );

pdcDest->StretchBlt( nX + 1, nY + 1, nWidth - 2, nHeight - 2, &dcSrc, 0, 0, bmpInfo.bmWidth, bmpInfo.bmHeight, SRCCOPY );

// draw pre-cut paper icon

ImagePreCutPaper.DrawImage( pdcDest, nWidth - 64, nHeight - 38, 64, 38 );

ImagePreCutPaper.DrawImage has following body:

ASSERT( pDC != NULL );

ASSERT( m_hBitmap != NULL );

// draw bitmap

CXTPImageManagerIcon::DrawAlphaBitmap( pDC, m_hBitmap, CPoint( nX, nY ), CSize( nWidth, nHeight ), CPoint( 0, 0 ), GetImageSize() );

Unfortunettly when i call this line my oryginal image disappears i see only new image but in fact i want to draw this new image over old image.

Everything works fine until I call this line.

Thanks for any help
