File|New

Clears the current application from the ObjectVision window.

Use File | New to start developing a new ObjectVision application.

You are prompted to save any changes you have made to the current application.

When you start ObjectVision, File | New is dimmed because a new file has been opened for you automatically.


File|Open

Loads an existing ObjectVision application from disk and displays the top form in the application stack.

Use File | Open to load a previously created application or one you have partially completed.

When you choose File | Open, a dialog box appears where you can select the directory and file name of the ObjectVision application. The default file extension is .OVD.

Because only one ObjectVision application can be open at a time, File | Open first clears any current application.

Passwords

If an application has been password protected, you must type the correct password in the Password box in order to modify that application. As you type, ObjectVision echoes only asterisks onscreen.

Additional information

File | Save As


File|Resume

Resumes guided completion to complete the initial Goal form.

Use File | Resume to restore the initial form and field sequence and to make ObjectVision prompt for any additional information needed to complete the Goal form.

File | Resume does not clear any information you have already entered.


File|Save

Saves the current ObjectVision application, including any changes, to disk for later use.

Use File | Save to save your changed application periodically.

You are not prompted for a file name unless the application is still untitled.

The application is written to the file you most recently specified using File | Open or File | Save As.


File|Save As

Saves the current ObjectVision application, including any changes, to disk for later use.

Use File | Save As to save your changed application into a new file without changing the original application.

A dialog box appears where you can select the directory and type the file name under which the application is to be saved. The default file extension is .OVD.


File|Print Form

Prints the currently active form.

Use File | Print Form to print only the top form.

If you print a form containing a table object connected to a database table, the form will be printed multiple times until every value in the table object has been printed.

You can also use File | Print Link to print all the values in the link. This might be limited by a restricted range. Note that links to table objects do not appear in the Print Link dialog box.

The form is printed on the printer currently selected for use with Windows. To change printers, use File | Printer Setup.


File|Print All

Prints all forms in the current ObjectVision application.

Use File | Print All to print all forms with their current contents.

If you print any form containing a table object connected to a database table, that form will be printed multiple times until every value in the table object has been printed.

You can also use File | Print Link to print all the values in the link. This might be limited by a restricted range. Note that links to table objects do not appear in the Print Link dialog box.

The forms are printed on the printer currently selected for use with Windows. To change printers, use File | Printer Setup.


File|Print Link

Use File | Print Link to print the active form until all values in the active link are printed.

File | Print Link opens the Link Print Iteration dialog box. From the list of links, choose the link you want to print. ObjectVision prints all values available through the link you chose.

-	If the link is connected to an ObjectVision field, the active form prints once for every record in the link.

-	If the link uses a Locate with the Restricted Range option, the active form prints only the records in that range.

To see an example of printing a link,

1.	Open the Order sample application (ORDER.OVD).

2.	Choose File | Print Link and select the orders link from the list.

ObjectVision prints all records in the orders link.

The forms are printed on the printer currently selected for use with Windows. To change printers, use File | Printer Setup.

Glossary
Glossary of terms

active form

the form currently being completed. It appears on top of all other forms in the application.

calculated field

a field that uses decision logic to determine its value. When selected, a calculated field is indicated by a solid outline with an inner dotted line.

Clipboard

a temporary holding place for objects or forms. When you cut or copy something in ObjectVision, it is placed in the Clipboard. You can paste the contents of the Clipboard into any ObjectVision application. When you cut or copy something else, it replaces the contents of the Clipboard.

DDE (Dynamic Data Exchange)

a Windows protocol for exchanging information between Windows applications. ObjectVision can create DDE links between two ObjectVision applications, or between ObjectVision and another DDE-supported application.

decision logic

a process defined as a series of small steps, or nodes. Decision logic is graphically represented for each field's tree.

event tree

a graphic representation of the logic and instructions used to recognize an event and initiate an action.

field

a uniquely named object that contains a value either entered by a user, calculated, or delivered by a link. A field that is not put on any form automatically appears on the Scratchpad form.

field sequence

the order of user movement through fields on a form. Field sequence is determined by the physical ordering of the fields from left to right and top to bottom.

font

a typestyle used for a field label, field value, or text object.

form

a uniquely named object that contains a collection of fields, analogous to a paper form. A form is the primary interface between ObjectVision applications and users.

form completion

when a user fills in an ObjectVision application's field values. After a form is completed, the status indicator in the title bar reads (Complete).

Goal form

the top form in the application's stack of forms. It appears when a user first opens the ObjectVision application. When another form is selected by the user (interrupting guided completion), it becomes the Goal form.

guided completion

When a user presses Enter, the next field requiring user input is selected. If a user interrupts this method of selection by selecting some other field, guided completion can be restarted with File | Resume.

links

the part of an ObjectVision application used to read from and write to ASCII, Paradox, dBASE-compatible, and Btrieve data files. Additionally, read and write links can be created for Dynamic Data Exchange (DDE) files. Links are created with the Tools | Links dialog box or by using @functions.

nesting level

in a tree, the number of positions from the root node. Branches that are the same distance from the root node are at the same nesting level.

node

an individual segment or step of calculation logic used to evaluate a field value. A node can be an empty node, a simple or complex branch node, a root node, or a conclusion node.

override

Unprotected calculated fields let a user enter a new value, thus overriding the calculated value. After a user overrides a calculated value, the field displays a dot pattern. Field | Calculate restores the calculated value.

protection

a field property you assign with Properties | Protection to keep users from changing a calculated field value or viewing a tree.

restricted range

a link option that specifies that only those records exactly matching an entered value are delivered to the form.

root node

the first (leftmost) segment of calculation logic in a value tree or event tree. The root node is the only node that doesn't have a condition.

Scratchpad form

the form ObjectVision automatically creates to display any field not on a form, when the user is required to enter a value in that field.

selected field

A selected field is outlined by a heavier line. Everything a user types appears in this area on the form.

stack

the order of forms in an ObjectVision application, displayed in the Stack Tool. The Goal form is at the top of the stack.

table object

an ObjectVision form object that displays sets of one or more database records at a time.

tree

a graphic display of calculations or actions. Trees are like flow charts because they evaluate a condition, then on the basis of the result perform the next branch or conclusion.

values

the data contained in fields. A user can type values, select them from a list, or check them; an ObjectVision application can calculate values or read them from an external data file.

value tree

a graphic representation of the logic and instructions used to evaluate a value and calculate a value.

Changing screen colors

ObjectVision uses the same screen colors as other applications running under Windows.

You can change window colors with the Windows Control Panel.


Exiting ObjectVision

You can leave ObjectVision in various ways:

Exiting ObjectVision

      - 	Use File | Exit to end the current session and release any system resources being used by ObjectVision.

      - 	Alternatively, choose Close from the Control Menu of the ObjectVision window.

      - 	You are prompted to save any changes you have made to the current ObjectVision application.

Suspending ObjectVision

      - 	Choose Minimize from the Control Menu of the ObjectVision window to pass control to another application under Windows.

      - 	Alternatively, click the minimize icon on the ObjectVision window.

      - 	To reactivate ObjectVision, click its icon and choose Restore or Maximize.

Closing windows

      - 	Choose Close from the Control Menu of the Windows Program Manager.

      - 	You  are prompted to save any changes you have made to the current ObjectVision application.


Moving forms

ObjectVision initially places each form at the center of the ObjectVision window. You can move forms from that position using either the keyboard or the mouse.

Mouse

      - 	Hold down the left mouse button while the mouse pointer is over the form's title bar.

      - 	Drag the form to its new position, then release the mouse button.

Keyboard

      - 	Press Alt+Hyphen (-) to access the Control Menu of the active form.

      - 	Choose Move from the Control Menu.

      - 	Reposition the form using the arrow keys.

      - 	Press Enter to confirm the new position.


Opening an application

You can select and open any ObjectVision application.

      - 	Use File | Open to select and open an application.

      - 	The file dialog box displays all ObjectVision applications in the current directory.

      - 	To see applications in another directory, type the path name of the directory instead of selecting a file name.


Overriding values

ObjectVision lets you change calculated values. The application developer, however, can restrict users from overriding a field's value.

Setting an Override

      - 	Select a calculated field.

      - 	Type or select a different value and press Enter, Tab, or Shift+Tab.

      - 	The new value does not change unless you supply a new override value or remove the override by using Field | Calculate.

Removing an Override

      - 	Select a calculated field that has been overridden.

      - 	Use Field | Calculate to restore the calculated value.


Printing forms

Forms are printed on the printer currently selected for Windows. To select a different printer, choose File | Printer Setup.

Individual forms

      - 	Select a form as the active form.

      - 	Use File | Print Form to print the form.

All forms

      - 	Use File | Print All to print all forms in an application.

      - 	Each form is printed on a separate page.

Linked values

      - 	Use File | Print Link to print the active form once for each value in the current link.


Saving completed forms

You can save completed or partially completed forms for future use with ObjectVision.

      - 	Use File | Save to save the current application with all its forms using the application's current file name.

      - 	Use File | Save As to save the current application with all its forms under a new or different file name.

However, saving a form this way with a single set of values uses a lot of disk space. That's why ObjectVision forms are usually saved separately from the values they display.

      - 	The values are stored in database tables (Paradox, dBASE, or Btrieve) or ASCII files.

      - 	Values can be in a file created by a DDE-supported Windows application.

      - 	Values from these sources are delivered to ObjectVision by links.


Selecting forms

ObjectVision initially selects the top form in the application stack as the active form. Other forms are automatically selected when information on them is needed.

You can also direct ObjectVision to open and display a specific form.

      - 	Use Form | Select to select a form.

      - 	Select the form name from the list of available forms.

      - 	The order of the forms in this list corresponds to their position in the application stack.

      - 	Once you select a form, it remains open until you close it.

Mouse only

      - 	Click any portion of a visible form to make that form active.


Using the Windows Clipboard

You can transfer information between form fields in ObjectVision and other applications using the Windows Clipboard.

The Clipboard can be used to hold any field value.

      - 	Use Edit | Cut or Edit | Copy to place information on the Clipboard.

      - 	Use Edit | Paste to insert information from the Clipboard.

      - 	Information stays on the Clipboard until replaced by another Edit | Cut or Edit | Copy.

      - 	Edit | Undo does not affect the Clipboard contents.


Viewing decision trees
Viewing trees

You can view value trees or event trees to determine the decision logic used in an ObjectVision application. However,viewing trees from form completion mode might be restricted for individual fields by the application developer.

To view value trees in form completion mode,

      - 	Use the Tab key or Field | Find to select a calculated field.

      - 	Use Field | Show Tree to display the tree associated with the field.

      - 	Browse through the tree using arrow keys, scroll bars, and Expand and Reduce commands.

      - 	Choose Close from the Tree window's Control Menu to return to form completion mode.

      - 	Mouse only:  Double click a calculated field.

To view a value or event tree in the Form Tool, right-click an object and choose Value Tree or Event Tree from the property inspector.
