Hi,

I have to create a round rect button with three images, one for left round shape one for middle portion of button and one for right side round shape. I just wanted to know how to add these round images on the button. So that button has a round shape. Here is my code in which I am able to add middle image.

void CRoundButton2::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{

        CDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
	ASSERT (pDC != NULL);
	// Should Buttons be generated?
	bool bGenerate = !m_rBtnSize.EqualRect(&lpDrawItemStruct->rcItem) || m_bRedraw;
	// If Rectangles of Button are not the same
	if (bGenerate)
	{
		// Generate Bitmap to hold Buttons
		GenButtonBMPs(pDC, lpDrawItemStruct->rcItem);
		// Redraw done
		m_bRedraw = false;
	}
	// Generate DC to draw in Memory
	CDC *MemDC = new CDC();
	MemDC->CreateCompatibleDC(pDC);
	HGDIOBJ hOldBmp = MemDC->SelectObject(m_tBmpBtn);
	CString sActualCaption;
	// Get actual caption
	GetWindowText(sActualCaption);
	// Check, if caption has changed
	if (sActualCaption != m_sOldCaption)
		bGenerate = true;
	// Store old caption
	m_sOldCaption = sActualCaption;
	// If Rectangles of Button are not the same
	if (bGenerate)
	{
		// Draw Buttons
		DrawButtonFace(MemDC);
		// Draw Button-Caption
		DrawButtonCaption(MemDC);
	}
	int nButtonState;
	nButtonState = BS_ENABLED;
	if (m_bIsHotButton && m_bMouseOnButton)
		nButtonState = BS_HOT;
	if ((lpDrawItemStruct->itemState & ODS_DISABLED) == ODS_DISABLED)
		nButtonState = BS_DISABLED;
	else
	{
		if ((lpDrawItemStruct->itemState & ODS_SELECTED) == ODS_SELECTED)
			nButtonState = BS_PRESSED;
		else
		{
			if (this->m_bIsChecked)
			{
				nButtonState = BS_CLICKED;
			}
		}
	}

        CBitmap bitmap2;
        bitmap2.LoadBitmap(IDB_BITMAP1);
        BITMAP bmpInfo;
        bitmap2.GetBitmap(&bmpInfo);
        CBitmap* pOldBitmap = MemDC->SelectObject(&bitmap2);
        //int nX = m_rBtnSize.left + (m_rBtnSize.Width() - bmpInfo.bmWidth) / 2;
        //int nY = m_rBtnSize.top + (m_rBtnSize.Height() - bmpInfo.bmHeight) / 2;

	// Copy correct Bitmap to Screen
	for ( int i = 0 ; i<117 ; i++)
	{
		MemDC->SelectObject(bitmap2);
		pDC->BitBlt(0+i,0,bmpInfo.bmWidth,bmpInfo.bmHeight, MemDC,0, 0, SRCCOPY);
		//MemDC->SelectObject(hOldBmp);
		MemDC->SelectObject(pOldBitmap);
	}
	UINT state = lpDrawItemStruct->itemState; //Get state of the button
	if ( (state & ODS_SELECTED) )            // If it is pressed
	    pDC->DrawEdge(m_rBtnSize,EDGE_SUNKEN,BF_RECT);    // Draw a sunken face
}

Please help me out..

Thanks in advance
