Furthermore, each block of the flowchart illustrations may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of the order. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved.

The present invention enables a user to change the "personality" of their desktop without actual changing the desktop itself. This is achieved by storing various attributes of the desktop and restoring them when the associated personality is selected.

Using embodiments of the present invention it is possible to set the visibility of the icons and the Run off area" for icons that are hidden or will not fit on the current available desktop area.

These two features allow personalization of the desktop across different user's machines, where the resolution may change, and configuration of the desktop icons to match the intended use of the machine for that session, for example: presentation desktop, office apps desktop and home use desktop.

Icon Positioning Windows icons are contained within a list view. The windows list view control contains the names, icon images and positions of each icon on the desktop. This embodiment uses windows list view messages to communicate with the list view; however the messages pass data via parameters that reference memory blocks and they will only access memory that is local to the process that owns the list view. Therefore it is necessary to ensure the memory used to transfer these parameters is in the same process as the list view. There are two standard ways to do this: inject a dIl into the target process, hence any messages passed will share the same memory space, or allocate memory in the target process and use this allocated memory with the list view messages. The present embodiment uses the latter method set out in more detail below with reference to the accompanying Figures 1-3.

Figure 1 is a schematic diagram of an electronic computer system 2 including a display screen 4, a display screen controller 6, a memory 8 and a processor 10. The display screen 4 includes a desktop window incorporating wallpaper 12 and a plurality of icons 14, which are a combination of short cuts and documents.

Figure 2 is a schematic diagram of elements of the display device controller 6. The display device controller 6 comprises a shell window locator 20, an icon position storer 22, icon position setter 24.

Figures 3A-3C are functional flow diagrams illustrating a method of operation of the apparatus of Figures 1 and 2.

Before storing or setting the positions of the icons on the desktop window it is necessary to find the desktop window. The method used to do this needs to be adaptive since it can vary depending on the operating system. According to this embodiment of the present invention, the method is as follows, described with reference additionally to Figure 2 of the accompanying drawings. The approach set out in relation to the present embodiment is for a Microsoft Windows (trade marks) operating system, but a person skilled in the art will appreciate that these can be adapted for other operating systems.

In step 100, shown in Figure 3A, the shell window is found by the shell window locator 20.

In step 100-2 first the system attempts to find the shell window by determining is "SHELLDLL_DefView" a child window of "Progman".

If the result of that is positive, i.e. "SHELLDLL_DefView" is a child window of "Progmanthen is step 100-4 the system uses Win32 FindWindowEx to find desktop window child called "Prog man".

If, however, the result of step 100-2 is negative then in step 100-6 (labeled 100-4 on Fig3A) it is determined "SHELLDLL_DefView" is a child of "WorkerW".

If it is positive then the handle have found is where SHELLDLL_DefView is a child of WorkerW in step 100-7.

If the result in step 100-6 is negative then in step 100-8 it is determined is "SHELLDLL_DefView" a child of a child of "Progman" using EnumWindows to enumerate all child windows looking for one called "SHELLDLL_DefView. If found this is returned in 100-10.

If the result in step 100-8 is negative, finally, in step 100-12 the system looks on other desktops using Win32 EnumDesktopWindows.

The desktop icons window is the child "SysListView32" of the shell window.

In step 102, shown in Figure 3B, positions of the icons present on the desktop are stored by the icon position storer 22.

In step 102-2 count the number of list view items on the Desktop Window: o LVM_GETITEMCOUNT In step 102-4 open the process that contains the desktop icons window: o Operation (access address space of process), Read, Write and Query access In step 102-6 allocate virtual memory in the process to hold a List View Item: o LVITEM In step 102-8 allocate virtual memory in the process to hold any text and the position co-ordinates. The virtual memory needs to be large enough for an icon name. Currently this is proposed to be 512 bytes but can be varied as required.

In step 102-10 for each list view item index, from 0 to the number of items determined in step 102-2: o Initialize the LVITEM and copy it to the virtual memory o Send the get item text message to the list view * LVM_GETITEMTEXTA o Read the text from the virtual memory o Send the get item position message to the list view * LVMGETITEMPOSITION o Read the position from the virtual memory o Store the position in our icon positions table (one table per personality) The positions of the icons on the desktop are then set in step 104, shown in Figure 3C, by the icon position setter 24.

In step 104-2 get the current list view style In step 104-4 determine if Auto Arrange is on.

In step 104-6 if Auto Arrange is on do nothing (since icons are auto arranged) In step 104-8 determine if Align icons to grid is on In step 104-10 if Align icons to grid is on, turn it off (it is turned back on when done) In step 104-12 count the number of list view items on the Desktop Window o LVM_GETITEMCOUNT In step 104-14 open the process that contains the desktop icons window o Operation (access address space of process), Read, Write and Query access In step 104-16 allocate virtual memory in the process to hold a List View Item o LVITEM In step 104-18 allocate virtual memory in the process to hold any text and the position co-ordinates, that needs to be large enough for an icon name (in this embodiment 512 bytes) In step 104-20 for each list view item index, from 0 to the number of items determined at step 102-2: o Initialize the LVITEM and copy it to the virtual memory o Send the get item text message to the list view * LVM_GETITEMTEXTA o Read the text from the virtual memory o Get the stored position from the personality table for the icon based on its name o If there is a stored position Send the set item position message to the list view

LVM_SETITEMPOSITION

In step 104-22 if Align icons was turned off, then turn it back on.

Visibility We propose the concept of dynamically choosing which icons to display for a particular desktop. One solution is to just move the icons to a position that is beyond the normal area of the desktop window. However this had two drawbacks: * The working area of the screen gets larger and larger as screens get bigger so the off screen area has to be very large (maximum x and y values are 32767) * The technique only works if align to grid is turned off. When align to grid is on then icons with co-ordinates outside of the visible area are placed in the nearest corner to the off screen co-ordinates.

So an alternative solution is used.

All desktop icons represent actual files in the desktop folders on the machine. Files on a machine have a set of attributes that can be applied to them. Three of these attributes; "Read Only", "System" and "Hidden" can be used to protect the file from the modification or deletion by the end user. The last two of these attributes also controls the visibility of the file to programs such as explorer and of course the desktop. Hidden files are not normally visible to the user. System files are considered "Super Hidden", examples of which are system critical files that the end user does not need to know about, such as the "desktop.ini" files in the desktop folders. Although some technical users may set the option to display "Hidden" files, allowing the system to also show "Super Hidden" files is not normal practice and indeed results in the desktop showing the two desktop.ini files which is unnecessary and confusing extra clutter on the desktop. Therefore in most cases setting a file in the desktop folder attributes to system and hidden will effectively remove it from the view.

As shown in Figure 4 of the accompanying drawings, the display device controller 6 further comprises a cache builder 26, name finder 28, flag remover 30, flag adder 32 and desktop refresher 34.

To hide and show the desktop icons the following steps are carried out when a desktop personality is applied as shown in Figure 5 of the accompanying drawings. This involves the steps of: In step 200-2 cache builder 26 builds a cache of information for all the files in the desktop folders (user and public) and store the name, icon bitmap, shortcut flag, path and attributes for each one.

In step 200-4 for each entry in the cache name finder 28 determines if the name exists in the current selected desktop personality.

In step 200-6, if the name exists in the current selected desktop personality, flag remover 30 removes any hidden or system flags on the file.

In step 200-8, if the name does not exist in the current selected desktop personality, flag adder 32 adds the hidden or system flags to the file.

Once icons have been shown and hidden then the desktop needs to be refreshed in step 200-by desktop refresher 34 before the icons are moved around.

In relation to a refresh, once an icons state, hidden or visible, has changed the system has to be told so that the desktop can correctly reflect the current state of all the icons. Without the refresh then until the user causes the desktop to refresh (pressing F5 on the desktop, adding a new desktop icon, deleting an icon etc.) the changes made to the files will not be shown.

To cause the screen to update, with minimum overhead, in step 200-10, the method calls the Win32 API "SHChangeNotify" specifying an association change event.

In practice there is still a slight delay when calling this function so the method includes the flush flag with the command and a small delay in the code before starting to update icon positions is an option. Although the windows API says the flush flag should apply all the changes to the icon visibility before the function returns, in practice this does not always work.

There can be an extra delay, dependent on the number of icons/changes to icons required. In development, this appeared to be about a second. If the icons do not move correctly when switching personalities it is possible to just re-selected the new personality to ask them to be moved again. Production code would do this in a neater way, perhaps waiting for another indication that the icons had all been unhidden before moving them, or checking they are all visible before moving them.

Icons that are either hidden or cannot fit on the current desktop due to space constraints are available in a run off area. This is a user displayable window that is usually docked on the right hand side of the screen and contains a list of the currently not visible icons. Icons in this area can be selected and dragged back onto the desktop, given sufficient space.

Icons currently on the desktop can be hidden using a simple extension to the right click context menu that offers a hide option. The current embodiment simply adds a shell extension (a registry key) that enables an extra menu item on the right click context menu when selecting files/icons on the desktop. Selecting hide would just run the dos Attrib command to apply the hidden and system flags (Attrib i-s i-h <filename>). Without the right click a user would need to open the folder in a cmd prompt box and type attrib by hand to hide the icon.

Wallpaper Setting the wallpaper is a two-step approach and is best done on a separate thread since the Win32 API call to refresh the display will block until it is completed and it is not necessary to wait for the call to complete.

Further elements of the display device controller 6 are illustrated schematically in the accompanying Figure 6 of the accompanying drawings. The display device controller further comprises a path storer 36 and a Windows updater 38.

The steps according to the present embodiment of the invention are illustrated in Figure 7 of the accompanying drawings and as follows: In step 300-2 the path storer 36 stores the path to the wallpaper file in the registry.

o Key = "HKCU\Software\Microsoft\lnternet Explorer\Desktop\General" o Value = "WallpaperSource" In step 300-4 the Windows updater 38 inform windows that the wallpaper has changed.

o Win32 API SystemParameterslnfo * Action = SPIDESKTOPWALLPAPER * Parameter = path to wallpaper file * Flags = SPIF_UPDATEINIFILE and SPIF_SENDWINIINICHANGE Preview Preview images of the desktop and associated icons, but not any open windows, are cached as jpeg images for use in helping the user pick the current desktop.

The wallpaper and icon combination is captured using the Win32 API call PrintWindow. This captures only the contents of the desktop window and not any running programs, since these would tend to obscure the icons and wallpaper.

Resolution As shown in Figure 8 of the accompanying drawings, the display device controller 6 further comprises a resolution storage unit 40 and a personality selection unit 42.

In order for the resolution to be set it first has to be read and stored as part of the personality of a particular desktop. Once this has been stored, from the current desktop resolution, setting the resolution of the screen is carried out using two Win32 API calls as illustrated in Figure 9 of the accompanying drawings. The resolution is stored in step 400 by resolution storage unit 40 and set when a user selects a new personality in step 402 by personality selection unit 42.

To store the resolution in step 400-2 read the Primary Screen Width and Height from the System Parameters.

To set the resolution (using a previously stored, and therefore valid, resolution), in step 402-2 enumerate the display settings for the current device Win32 API EnumDisplaySettings In step 402-4 check if the new settings, width and height, are different from the current settings or the same.

In step 402-6, if different update with new values * Call ChangeDisplaySettings (CDS_TEST flag) * Call ChangeDisplaySettings (CDS_UPDATEREGISTRY flag) In step 402-8, if the same, do nothing.

Personality Setting A new personality can be created at any time by modifying an existing personality and by keypress combination or context menu choice saving the modified personality with a new file name e.g. work, presentations, home, gaming, family, etc. An existing personality can be modified by e.g. right clicking on the wallpaper to change the wallpaper or resolution in a contextual menu or an icon can be moved by dragging it to another part of the screen. An icon can be marked as not visible by right clicking on it and selecting that option from a contextual menu. Once hidden it should also appear in the run off area so it can be un-hidden if required.

Personality Switching The personality of a particular desktop is just a list of settings that need to be applied to re-create the desired desktop personality. The list includes all the settings discussed above grouped into collections of personalities.

A new personality can be chosen and applied using a simple keypress combination, context menu choice or interactive preview.

Although the prototype code creates personalities on request by the user, since this gives the most control and stops the user from "accidently" erasing the "perfect layout", they could just as easily be created automatically when the user switched desktop or any other suitable trigger.

Apart from when the personality is being stored or applied the desktop selector remains idle and does not need to interact or monitor the desktop in any way. This provides a light weight but powerful tool for desktop selection.

The present invention extends to a computer programmed to carry out the claimed method and to a computer readable media carrying a computer program for the method of the present invention. Such a computer readable media may include a DVD, a CD or another computer from which the program can be downloaded, e.g. via the internet.
