How can a dialog have two different icons?

Hi

I am trying to make my application, which is an MFC dialog based application, have the titlebar/system menu icon different from the one showing in the taskbar.

How can this be achieved?

Thanks

As far as I know there is only 1 icon. What you could do is handle the minimize/restore events yourself and change the icon when the window is minimized or restored.

Is there any reason to change the windows default behavior ?

My dialog application can open different dialogs each with its unique icon.. I want all those dialogs to have different icons in their system tray yet they all share the same icon in the taskbar.

Using CWnd::SetIcon

SetIcon will set the icon for both the title bar and the task bar icons

Yes, you are right!
And sorry! I never changed the icon of the main dialog of a dialog based app, I only did it for child windows.

I wanted to suggest a hack, hoping that Windows uses different resolution of the same icon in the title bar and task bar.
Sorry, no luck – on my system they both use 32x32, 32-bit.
I guess you’d have to handle non-client painting yourself.

I wont mind doing that except I'm not what the right approach is or how can I get a handle to the taskbar button

I would suggest to leave the task bar alone (use SetIcon there), and handle NC_PAINT to paint different icon on the title bar of your window.

Yeah, I did the same test after OP had coplained in the post#6! And couldn't achieve it either. :eek:

Handling WM_GETICON does the trick. See the sample.
