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
the problem.

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.
