Re: Vista Aero

Hi, David
below is a snippet of my code.about drawing scrollbar.
note: it can be displayed normally unless Aero in vista is enabled.
thanks once again and hope response.

//// a snippet of my code
void CMyScrollBar::OnPaint()
{
     CPaintDC dc(this);
     // draw scrollbar when receive the on_paint message
     DrawScrollBarDC(&dc);
}
//// draw scrollbar
void CMyScrollBar::DrawScrollBarDC(CDC *pDC)
{
     CRect clientRect;
     CDC memDC;
     CBitmap tempBmp,*oldBmp;
     GetClientRect(&clientRect);
     if(clientRect.Width()<=0) return;

     memDC.CreateCompatibleDC(pDC);

tempBmp.CreateCompatibleBitmap(pDC,rectClient.Width(),rectClient.Height());
     oldBmp = memDC.SelectObject(&tempBmp);
     memDC.SetStretchBltMode(COLORONCOLOR);
     memDC.FillSolidRect(rectClient,RGB(255,0,0));
     // draw the scrollbar image
     if(m_bReDraw) DrawScrollBar(&memDC);

     // i had copied the memDC to clipboard from here
     // and then paste to word document, the image is right
     // so why bitBlt can't blit the image normally?
     pDC->BitBlt(0,0,
rectClient.Width(),rectClient.Height(),&memDC,0,0,SRCCOPY);
     // dw is 0 anyway
     DWORD dw = GetLastError();

     memDC.SelectObject(oldBmp);
     tempBmp.DeleteObject();
     memDC.DeleteDC();
}
