Use
USING...

To configure Caledos, you must run Windows Control Panel and click twice on the Wallpaper Changer icon.

Once the program starts, it shows a dialog box that allows you to choose which .BMP images are to be displayed, and the time interval between wallpaper changes: to add an image to the list, you must enter the list on the left with your mouse pointer, and browse the directory until you find the bitmap file you want; select the file name with a click and then press the [image] button, or double-click the file name: the selected file name will appear in the list on the right, which contains the names of the images used as wallpaper. You can add a wallpaper with Drag and Drop method too, dragging a bitmap from the Explorer to the list box on the right.

To add all file .BMP of current directory press [image] button.

To remove a file name from the list box on the right, you have to select it with a mouse click and then press the [image] button, or double-click the file name.

To remove the whole list of selected images, use the [image] button.

To change ‘now’ the wallpaper with the selected bitmap, use the [image] button. Remember, if you turn off the ON button you can use caledos like an normal (i.e. not automatic) wallpaper changer that support the JPeg format !

You can do all the operation on both the list box via the Context Menu too !

By checking / un-checking the ON button you can enable/disable Caledos; when the program is disabled in this way, it doesn't change the wallpaper, but still retains the list of selected images.

The RANDOM button, if checked, allows Caledos to choose randomly the next wallpaper from the selected images list each time the wallpaper needs to be changed; otherwise the selected bitmaps are used in the order they are listed in.

If the FORCE CHANGE button is off then on startup, caledos updates the wallpaper, but it will show it next time that you’ll run Windows.

The JPeg -> 256 COLORS button allows you to convert the JPeg file from 16M colors to 256 colors dithered before use it. I suggest to use this options if :

•	your display support only 256 colors, or if

•	your computer have less of 16Mb of RAM or if

•	your computer is an old 486DX33 or lower, or if

•	your video card isn’t PCI or if

•	your computer decreases its performance with ‘big’ Wallpapers

(obviously, this option is active only if you have installed the JPeg Support !)

The TILE and CENTRE buttons determine the way the wallpaper is displayed. If CENTRE is checked, there will be one copy of the bitmap at the centre of the screen; otherwise, if TILE is checked, the screen is filled with as many copies of the bitmap as it will needs, arranged like tiles.

The OK APPLY CANCEL and HELP button have the typical Windows use.

HOW DOES IT WORK

When you install the program, the file CALEDOS.EXE (the effective wallpaper changer) is copied into the Windows directory. Then, each time Windows starts up, CALEDOS.EXE reads from the Registry HKEY_CURRENT_USER/ SOFTWARE/delfinosoft/caledos (also in the Windows directory) the information it needs (wallpapers list, change frequency etc.) in order to determine the appropriate wallpaper, and sets a line   Wallpaper=... in the HKEY_CURRENT_USER/ Control Panel/ Desktop/ section of the Registry file.

CALEDOS.CPL, accessible through the Control Panel, modifies the contents of HKEY_LOCAL_MACHINE/ SOFTWARE/ DelfinoSoft/Caledos.

NOTE:

since Caledos modifies Registry when Windows is already running, the change will have no effect until the next Windows startup (if you haven’t select “Force Change Options”). This means, for example, that if you configure Caledos to modify the wallpaper every week, the change will become effective from the 2nd time you run Windows in the 7th day.

The JPeg support is possible for the work of the “Indipendent JPEG Group”.

Caledos has been developed using the Microsoft Visual C++ 4.0. It does not use object oriented programming since it uses extensively the Windows API interface. However, some of the C extension have been used, so the source cannot be compiled with a pure C compiler.

This help file has been developed with Microsoft Help Workshop 4.0 + Microsoft WinWord 7.0.

That's all, folks!
