CFrameWnd icon doesn't appear in Taskbar
I've created a setup-style program with the background screen-filling wnd derived from CFrameWnd (MFC 2.5). The icon and text doesn't appear in the taskbar under Windows 95 although it appears correctly in the Task-switcher (ALT-TAB).
What's going on here? Normal 16-bit MFC apps with CFrameWnd frames normally appear in the taskbar. What is it that makes a top-level window appear or not?

Sorry, AVaulin. I found some 16-bit applications whose frame windows do not have WS_CAPTION style (no title bars) still appear in the taskbar. I do not know the exact reason.
I said about WS_CAPTION but may be WS_SYSMENU is what I must say. I recently wrote program. MainFrame has only WS_VISIBLE and WS_BORDER styles. Only window text appear in TaskBar (icon appear with text only if ALT-TAB pressed).

It seems to be a combination of WS_SYSMENU and WS_CAPTION styles, I've just tried it. Now I've just got to try and remove the caption without removing the taskbar button!
Thanks both for your help.

A taskbar button is placed on the taskbar whenever an application creates a unowned primary window. To ensure that the window button is placed on the taskbar, create the window by calling CreateWindowEx and include the WS_EX_APPWINDOW style. To prevent the window button from being placed on the taskbar, create the window by calling CreateWindowEx and include the WS_EX_TOOLWINDOW style. As an alternative, you can create a hidden window and make it the owner of your primary window.The window button typically contains the application icon and title. However, if the application does not contain a window menu,the window button is created without the icon.
To remove application from task switcher you have to hide the window.

Thanks Lizer,
I'll try that and see where I get to. I was faced with the choice of either no taskbar button or having a meaningless caption bar at the top of my setup screen background.
It sounds lilke you've given me the answer I needed.

There are no WS_EX_APPWINDOW and WS_EX_TOOLWINDOW styles in 16-bit SDK.

I found them in the Visual C++ 4.0 header files and just used the WS_EX_APPWINDOW style as a manifest constant. It works fine as a 16-bit app under Windows 95 (I assume the style is ignored by Windows 3.1 as undefined, though I haven't tried that yet). In any case it's irrelevant to 16-bit Windows, with no taskbar. Thanks again, Lizer.
