HOWTO: Set the Title Bar Icon in a Dialog BoxLast reviewed: January 23, 1998Article ID: Q179582 |
The information in this article applies to:
SUMMARYYou can enable your application to display an icon in the title bar of a dialog box by adding the WS_SYSMENU and WS_CAPTION styles to the dialog box template and sending the WM_SETICON message from within the dialog box procedure in response to the WM_INITDIALOG message.
MORE INFORMATIONOn Windows 95 and Windows NT 4.0, any popup or overlapped window can display a small icon for the system menu icon. Dialog boxes on Windows 95 and Windows NT 4.0 do not display a small icon on their system menus by default. If you want the dialog box to display its own icon for the system menu, add the WS_CAPTION and WS_SYSMENU styles to the dialog box template and send the WM_SETICON message when the dialog box procedure is called with the WM_INITDIALOG message. Send the WM_SETICON message to change or set the small and large icons of a window. In this case, because you are setting the small icon, wParam must be set to the ICON_SMALL value. The following sample code assumes that the dialog box template has the WS_CAPTION and WS_SYSMENU styles in addition to any other styles required.
Sample Code
case WM_INITDIALOG: { HICON hIcon; hIcon = LoadImage( g_hInst, MAKEINTRESOURCE(IDI_MAIN_ICON), IMAGE_ICON, GetSystemMetrics(SM_CXSMICON), GetSystemMetrics(SM_CYSMICON), 0); if(hIcon) { SendMessage(hWnd, WM_SETICON, ICON_SMALL, (LPARAM)hIcon); } } return TRUE; |
