-
- This document describes the sample program files, which are installed
- in the SAMPLES subdirectory.
-
- Several programs use Bladerunner's new Open Window syntax, which lets
- you run multiple programs simultaneously. For example, start Contact.prg
- by either typing DO CONTACT in the Command Window or double-clicking on
- its icon in the File Viewer. After Contact's window appears, you can
- start Winapi.prg, again either through the Command Window or the File
- Viewer, and switch freely between the two windows.

-
- ANIMALS.PRG
- -----------
-
- Files used: Animals.dbf, Animals.dbt
-
- This program shows how Bladerunner's window objects defined on database
- fields are related and change as the record pointer changes. It also
- displays Bladerunner's imaging commands.
-
- A window is defined with a listbox of image names and the image
- corresponding to the currently highlighted name. The image is stored in
- a memo field in Animals.dbf.
-
- BINTREE.PRG
- -----------
-
- Files used: Clients.dbf, Clients.dbt
-
- This program shows how you can use Bladerunner's object extensions to create
- a binary tree. It builds a tree of clients' names, from clients.dbf, in
- alphabetical order. The tree goes left to right alphabetically, i.e. left
- child, parent, right child.
-
-
- CONTACT.PRG
- -----------
-
- Files used: Company.dbf, Summary.dbf, Summary.mdx, Contact.dbf, Contact.mdx,
- Company.dbt, Company.mdx, Sampproc.prg
-
- This program relates 3 tables, and shows how Bladerunner's window controls
- work together and change as the record pointer moves in the main table.
- It defines a window with a listbox containing the names of companies,
- a radiobutton with company types, and an editor showing notes for a company.
- You can select the "Browse" pushbutton to browse the whole table of
- companies or the "Graph" pushbutton to look at the regression graph of the
- currently selected company's figures. All non-pushbutton controls change as
- you move through the listbox to reflect the current state of all related
- tables.
-
-
- DLLSAMP.PRG
- -----------
-
- Calls: MessageBox() (external function)
-
- This program makes an API call to the Windows function MessageBox(), which
- brings up a dialog corresponding to the parameters specified in this
- function. It shows how easily Bladerunner can interface with external
- libraries.
-
-
- DUMP.PRG
- --------
-
- Parameters: O (name of an object)
-
- This program lets you view the name and value of each property
- in the parameter object by calling the enum() function. Enum() creates
- a linked list of the object's properties. For instance, you can create a
- window, MyWindow, and can view its properties with:
-
- MyWindow = NEW Window()
- DO DUMP WITH MyWindow
-
-
- EVENT.PRG
- ---------
-
- Files used: Sampproc.prg
-
- This is a procedure file containing event-driven functions. If you DO Event,
- you can then call MakeButtonWindow() which creates a window with one
- pushbutton. Clicking on different areas in the window will move the button
- to that spot, and change the button's caption to show the current
- coordinates. Shift-click creates a new button, and Ctrl-click aligns all
- buttons.
-
- You can also call MakeSizeWindow() which will change its size as you move
- the mouse. Each of these events is made possible by Bladerunner's event
- handling functions, which can be assigned to different objects, and executed
- as the event happens. Here, for example, the events are pressing down the
- left mouse button, moving the mouse, and changing the size of the window.
-
-
- FOCUS2.PRG
- ----------
-
- Files used: Sampproc.prg
-
- This program creates 2 instances of a user-defined window class, and then
- changes the properties of each of the windows depending on which one has
- focus. It uses the OnGotFocus and OnLostFocus event handlers to trap
- and change the current state of the current window's caption and contents.
- This is a simple but powerful example of how Bladerunner's object syntax
- handles events.
-
- The core of FOCUS2 is just 3 lines of code. These three lines set a
- procedure, and create two window objects. After that, everything is
- handled either automatically, or by the members of the window objects.
-
-
- FONT.PRG
- --------
-
- Shows how to set different fonts and colors for Bladerunner's window
- controls. Currently fonts can be set for text, entryfields, and pushbuttons.
-
-
- GRF.PRG
- -------
-
- Files used: Sixgraph.dbf, Bar.grf, Pie.grf, Line.grf, Regr.grf, Scat.grf,
- Step.grf
-
- Defines a window with 6 different graph objects. This program shows the
- different types of graphs you can use and create using Bladerunner. Each
- graph shows a different view of research data collected in sixgraph.dbf.
-
-
- IMAGE.PRG
- ---------
-
- Files used: Country.dbf, Country.dbt, Eurpie.grf
-
- Brings up a window containing a representation of the GNP of some European
- countries. The GNP is represented in a pie graph object. The window also
- contains an image of a map of Europe with the currently selected country
- highlighted. Selecting a slice of the pie changes the map to the
- corresponding country, and shows the name of the country and its capital.
-
-
- LINKLIST.PRG
- ------------
-
- This is a simple program that creates a linked list of integers from 1 to
- 10. Each link has a value and next properties. After the list is created,
- a function is called to step through it and display the contents of each
- link.
-
-
- OPENWIND.PRG
- ------------
-
- Files used: Country.dbf, Country.dbt, Sampproc.prg
-
- This program shows how Bladerunner's OPEN WINDOW command works.
- OPEN WINDOW displays a window and enables the objects it contains, but
- doesn't stop program control flow.
-
- In this program, you can select a country in one window, then view
- information about that country in a second window. You can then select
- more countries from the first window, and bring up windows with information
- about them. All information windows will stay on the screen until you
- close them.
-
-
-
-
- PICTURES.PRG
- ------------
-
- Files used: Pictures.dbf, Pictures.dbt
-
- This program shows how Bladerunner's window objects defined on table
- fields are related and change as the record pointer changes. It also
- displays Bladerunner's imaging and sound commands.
-
- A window is defined with a listbox of image names and the image corresponding
- to the currently highlighted name. There is also a sound button that will
- play a sound corresponding to the image. Both the image and the sound are
- stored in memo fields in Pictures.dbf.
-
-
-
- PUZZLE.PRG
- ----------
-
- Calls: Sampproc.prg,
- DeleteObject(),SelectObject(),CreatePen(),GetDC(),ReleaseDC()
- MoveTo(),LineTo(),SetTextColor(),FillRect(),CreateSolidBrush()
- (external functions)
-
-
- This program shows how you can use the object syntax to create a simple game.
- It also shows how the object extensions and windows API functions can be used
- to create a simple painter.
-
- A window is displayed with three pushbuttons -- Puzzle, Draw Window,
- Paint Window. The Puzzle pushbutton creates a window with a 15 button
- puzzle. The Draw Window pushbutton creates a window that lets you paint rays
- in different colors, and the Paint Window creates a window that lets you draw
- different colored lines. You can create as many windows as you like with
- each activity. Puzzle.prg is programmed using Bladerunner's object syntax,
- and is completely event driven.
-
-
-
-
- SHOWPROP.PRG
- ------------
-
- This is an introduction to Bladerunner's object extensions. It shows how
- most Bladerunner objects can be accessed dynamically using object syntax.
- Showprop accesses and changes different properties of the Bladerunner frame
- and Command windows, creates sparse arrays using the object syntax, and
- shows how you can use the enum() function to view all the properties of
- an object.
-
-
-
-
- TESTCLAS.PRG
- ------------
-
- This program shows how to use Bladerunner's object syntax to create
- base classes and derived classes. It defines 2 classes -- MyClass and Base,
- and a class Derived, which is derived from the Base class. It then creates
- instances of each of these classes, and displays their properties.
-
-
-
- WINAPI.PRG
- ----------
-
-
- Files used: Sampproc.prg
-
- Calls: Sampproc.prg,
- GetVersion(),GetWinFlags(),GetModuleUsage(),GetModuleHandle(),
- GetVersion(),ShowWindow(),GetFreeSpace(),SystemParametersInfo(),
- messagebox(),SystemParametersInfo(),CloseWindow(),OpenIcon(),
- GetWindowText(),CloseWindow(),OpenIcon(),GetWindowsDirectory()
- (external functions)
-
- This program gives extensive examples of how you can use Bladerunner's API
- interface to access Windows' functions and obtain useful information.
- It brings up a window that lets you select what external functions/groups
- of functions you would like to execute, and then executes your selection.
- You can get various system information, bring up Windows dialogs,
- minimize/maximize Bladerunner windows, and much more.
