- Database demo. Exercises the FormulaBuilder data-aware classes
-
- File DBFRMBLD.DPR
- Demonstrates a dialog to build database expressions
-
- File EIS*.DPR
- Demonstrate the merits of events to handle variables. Discussed in
- the Online Help.
-
- File FBDEMO.DPR
- A program which demonstrates the range of expression types
- possible with FormulaBuilder

-
- FILES
-
- File ABOUTFM.PAS:
- About form for Main Demo
-
- File CALCFRM1.PAS, CALCFRM1.DFM
- Demo of a calculator. Supports Variables
-
- File CALCDRVR.DFM, CALCDRVR.PAS:
- Driver Stub for Calculator Example
-
- File DBEXPRFM.DFM, DBEXPRFM.PAS:
- Allows the user to visually construct an expression based on
- a BDE database. Returns TRUE if a valid expression was entered,
- FALSE otherwise. If false, the original expression text is
- restored to the TDBExpression instance.
-
- File DBFUNCS.PAS:
- This unit demonstrates advanced function implementation techniques.
- Implements the functions :
-
- DBSUM( Expression <,Criteria > )
- DBAVG( Expression <,Criteria > )
- DBMAX( Expression <,Criteria > )
- DBMIN( Expression <,Criteria > )
- DBCOUNT(< Criteria >)
-
- File EIS1.PAS:
- First demo of the EIS series. Demonstrates the inefficiency
- of using the usual methods of variable handling in cases where
- variable data is voluminous and changes frequently
-
- File EISCBKFM.DFM, EISCBKFM.PAS
- EIS Demo using callbacks. Note that for the sake of brevity,
- Database variables are not handled.
-
- File EISFM.DFM, EISFM.PAS
- Revised EIS Demo - Access to spreadsheet data is now handled
- by form level methods and linked to the the onXXX events of
- of the Expression instance. NOTE ! - For the sake of brevity, this
- example does not handle Database variables
-
- File EXPRLIST.TXT
- FormulaBuilder expression test set.
-
- File EXTFUNC.PAS:
- External Function Module for FormulaBuilder Main Demo. Demonstrates
- the process of registering user-defined functions and constants
- with the engine.
-
-
- File FLTDEMFM.PAS:
- Used by the DBDEMO project.
-
-
- File FBHELPFM.PAS:
- Simple Notebook based help for FormulaBuilder Demo
-
- File FILTRFRM.PAS:
- This unit defines a form TFilterFm which permits the
- user to visually build an expression based on a BDE
- dataset. Uses the TDSFilter class.
-
-
- File FUNCDLG.PAS, FUNCDLG.DFM
- Dialog which lists all functions registered with the FormulaBuilder
- Engine
-
-
- File HLPXAMPL.PAS:
- This unit implements the functions discussed in the online help.
- To use these functions, simply include this unit in the USES
- statement of any unit in your project (they register and unregister
- automatically.
-
- File MAINFORM.DFM, MAINFORM.PAS:
- Main Form of the main FormulaBuilder Demo
-
- File NEWVARFM.PAS:
- Form to allow the addition of a variable to an expression
- Uses DLL level calls via the expression handle.
-
-
- File SSHEET.PAS:
- Unit which defines a dummy spreadsheet matrix object for use with
- the EIS demo series
-
-
- File RTTIFM.DFM, RTTIFM.PAS:
- RTTI Demo Form. Demonstrates the use of the TRTTIExpression class
-
-
- File TESTFRM.DFM, TESTFRM.PAS:
- This unit implements a simple demo of FormulaBuilder using
- DLL level calls
-
-
- File VARDLG.DFM, VARDLG.PAS:
- Simple Form & Unit to handle variables belonging to expressions
- Uses the Handle property and DLL level calls
-
-
- File VARXMPFM.DFM, VARXMPL.PAS:
- Simple demonstration of the different variable access methods of
- a TExpression. Also demonstrates registering a new function with
- the engine.
