set WNDCLASS.hIcon before you register the class for your main window.

MSDN Library January 2001 / Platform SDK / User Interface Services /
Windows user Interface / Windowing / Windows / About Windows /
Application Windows, in the section heading "Nonclient Area":

    ``The title bar displays an application-defined icon and line of
    text; typically, the text specifies the name of the application or
    indicates the purpose of the window. An application specifies the
    icon and text when creating the window. The title bar also makes
    it possible for the user to move the window by using a mouse or
    other pointing device.''

and in the reference for WNDCLASS:

    hIcon 
    Handle to the class icon. This member must be a handle to an icon
    resource. If this member is NULL, the system provides a default
    icon. 

I beleive this is where you set it.

There's also a hIconSm in the WNDCLASSEX structure.

hIconSm 
    Handle to a small icon that is associated with the window class. 
    If this member is NULL, the system searches the icon resource 
    specified by the hIcon member for an icon of the appropriate size 
    to use as the small icon.

It even has a useful "search" field (though I wish the default search 
scope would exclude all that Windows CE nonsense :-)

Just incase you meant dynamically, you can use WM_SETICON to do the same
thing at any time while your program is running.

RE: [GD-Windows] Icon for game window

[Brian H. <bri...@py...>]

A-ha!  I was doing that, however I botched up the call to LoadIcon by
passing NULL as the first parameter instead of hInstance.  Doh.

Thanks!

RE: [GD-Windows] Icon for game window

[Roland <ro...@wi...>]

Some more tips for icon handling:

Icons can store multiple resolutions of the image in one file. Usually
Windows finds the correct resolution to display, but sometimes this
fails: In my particular case it fails whenever one creates a MFC
dialog-based app. The wizard constructs code like this (in
CXYZDlg::OnInitDialog()):

	// Set the icon for this dialog.  The framework does this
automatically
	//  when the application's main window is not a dialog
	SetIcon(m_hIcon, TRUE);			// Set big icon
	SetIcon(m_hIcon, FALSE);		// Set small icon

The 'big icon' is displayed in the little ALT-TAB selection window.
The 'small icon' is painted in the title bar and in the task bar
entry.

The problem is that this call always loads the big resolution of the
icon. This looks good in the ALT-TAB case, but the title bar and task
bar icon is resized (instead of taking the nicer-looking smaller
resolution). My usual workaround is as follows:

    SetIcon(m_hIcon, TRUE);			// Set big icon
    SetIcon((HICON)
        LoadImage(
        AfxGetResourceHandle(),
        MAKEINTRESOURCE(IDR_MAINFRAME),
        IMAGE_ICON,
        16,
        16,
        LR_DEFAULTCOLOR), FALSE);		// Set small icon

and voila: the small icon looks clean and nifty...

Isn't directly related to your problem, though....

RE: [GD-Windows] Icon for game window

[Brian H. <bri...@py...>]

Jon,

Thanks for the tip on searching MSDN, however, as you noted, the WinCE
references and technical articles from Win3.0 are a bit much =)
However, more important, I thought I WAS doing the right thing with the
WNDCLASS structure, which is why I ended up asking this list (i.e. the
icon was showing up fine on the desktop just not in the titlebar, so I
had assumed that the two were different, when in fact I should have more
correctly assumed I was a dork and getting something wrong =) ).

As I said in the other e-mail, I was botching the call to LoadIcon(), so
the problem was further upstream than I had expected.

Thanks again,

Brian

I've come to read the URLs directly, as they list the platform 
type in there. As long as the real hit is on the first page I'm 
usually doing OK :-)

Yes, I saw that: our messages crossed in the mail. My apologies.
