I think removing

switch(nCtlColor)
{
case CTLCOLOR_STATIC:
  if (pWnd->m_hWnd == m_StaticIcon.m_hWnd)
  {
   pDC->SetBkMode(TRANSPARENT);
   return (HBRUSH)(GetStockObject(NULL_BRUSH));
  }
  break;
}

from your OnCtlColor function helps in showing the background that you
want.

Yes, it shows correctly. But the rest area of the icon, (which should be
transparent) is painted with black color.

Does the icon show up if you don't use transparent style?

I have two suggestions

1. You don't need to set transparent style each time OnCtlColor method
gets exectued. Instead use WS_EX_TRANSPARENT while creating the
CStatic window . You need to use CreateEx method to set this style at
the time of window creation.

2. I see CRect(0, 0, 0, 0) in the parameter list of Create method. Did
you try setting correct rectangle values?

HICON hIcon = ::LoadIcon(AfxGetResourceHandle(), MAKEINTRESOURCE(ICON_ID));
m_StaticIcon.SetIcon(hIcon);
.........

}

In CMyDialog:nPaint(), I have painted a region of CDialog with
GradientFill(...), and on this area I want a static icon, which needs to be
transparent. So that I can see the background of CStatic icon as gradient.

Can you paste the code that you have? That should help in identifying

Hi,

I am using the API CStatic::SetIcon to associate the icon with the static
control. I have placed this control on CDialog, (Dialog background is
gradient painted). I want this CStatic control to be transparent (so that the
background of CStatic would be gradient, which is of Dialogs background
color). However, icon image is transparent. How could I do this ?

Any help would be highly appreciated.

Thanks,
Paresh.
