Flowgorithm v4.1.0

Application Customization Settings

Flowgorithm versions 1.8 (and later) use the registry to store user settings. These include the application’s language, colours, chart style, and the maximum size of the internal stack.

Administrator Only Keys

The following three settings cannot be changed (or seen) by the user. They will only be accessed from the LOCAL_MACHINE hive.

Key	Default	App Can Change?	Description
Max Stack Size	5000	No	Contains the maximum size of the stack. If the application exceeds this size, it will display a Stack Overflow Error. This setting cannot be changed from within the application. In practice, this value should never be reached unless the programmer creates an infinite recursive call.
Turtle Buffer Size	8000	No	The Turtle Graphics Window keeps track of all the drawing commands sent to it.
Allow Source Code Viewer	True	No	If set to False, the Source Code Viewer will be hidden. It will not appear on the toolbar, in the main menu, or the Layout Windows tool.
Error Auto Wait	True	No	If set the true (default), the system will pause if the same exact error occurs twice in a row.  The “Ok” button on the Error Window will take 5 seconds before it can be clicked. This can prevent the student from nonchalantly closing the window (without bothering to read it).

User Only Keys

The following keys will only be applied to CURRENT_USER. Even if the application is open in Administrator Mode, these will be saved to the current user hive.

Key	Default	App Can Change?	Description
MRU 0	Null string	Yes	Most recently used file list.
MRU 1	Null string	Yes	Most recently used file list.
MRU 2	Null string	Yes	Most recently used file list.
MRU 3	Null string	Yes	Most recently used file list.
MRU 4	Null string	Yes	Most recently used file list.

Standard Registry Keys

Flowgorithm uses both CURRENT_USER and LOCAL_MACHINE. If settings are not found in CURRENT_USER, it checks LOCAL_MACHINE. The hive paths are identical. So, Flowgorithm will look for settings in the following order:

1. CURRENT_USER
2. LOCAL_MACHINE

If the application is started in Administrator Mode, Flowgorithm will save its settings to LOCAL_MACHINE. Otherwise, it will store them in CURRENT_USER.

So, if you want to set defaults for all users in the lab, please open the application in Administrator Mode and set the language, colours, etc… Any new user (who does not have user settings set), will use these defaults.

Root Folder

Key	Default	App Can Change?	Description
Chart Style	Default	Yes	Contains the name of the current chart style such as “Default”, “Classic”, etc… If the value of this key is not recognized, the application will use “Default”. If the user loads a chart style file, this key will be set to “Custom” and color values will be read from a “Shapes” subfolder of the Flowgorithm folder.
Color Scheme	Pastel	Yes	Contains the name of the current color scheme such as “Pastel”, “Cyberspace”, etc… If the value of the key is invalid, the application will default to “Pastel”. If the user loads a color scheme file, this key will be set to “Custom” and color values will be read from a “Color” subfolder of the Flowgorithm folder.
Language	en	Yes	Contains the ISO language code of the displayed language. If invalid, it will default to “en” (English).

Printer Registry Folder

In version 2.6.0, and later, Flowgorithm saves printer information to the registry.

Key	Default	App Can Change?	Description
Landscape	False	Yes	Boolean value that specifies if the printer will default ot landscape (true) or portrait (false)

Margin Top	0.75	Yes	Margin in inches.
Name		Yes	Name of the last printer used.

Source Code Viewer Registry Folder

Customizable colour schemes were added in version 2.5.

If the user loads a colour scheme file (or edits the current one using the application), the “Color Scheme” key is set to “Custom” and colours are stored in “Colors” subfolder of Flowgorithm. If the main “Color Scheme” is set to anything else, these keys are ignored.
