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....
