  • the development software 11231b uses unchanged the following controls: lines. Their appearance and behavior are the same as in a conventional Visual Basic environment.
  • the software 11231b modifies the behavior of the following pre-existing controls: command buttons, images, labels, text boxes, list boxes, shapes and timers. (The behavior of a customized (modified) control may depend on the mode (script or VB) of its use.)

  • FontSize, Caption and Style properties are available as in Visual Basic, the Caption property may not be used to create keyboard shortcuts - - - IMAGES
  • the size of an image on a device 120 depends on its pixel dimensions.
  • An image displays on the device 120 with the same number of pixels as the image on the host display. (An image may be adjusted once placed on a form but looks better if adjusted in the image-generating application.)
  • the label control works as in a conventional Visual Basic environment with the exception that text does not wrap. Therefore, in the development-software environment, multiple labels are used for multiple lines of text.

  • the development software 11231b creates a hidden button in front of the label and assigns the _Click-event code to that hidden button.

  • a line control behaves as it does in Visual Basic.
  • the Visible, XI, Yl, X2 and Y2 properties are available. --- LIST BOXES
  • a list box control behaves like a serial marquee: A sequence of words (a line of text, for example) appears one word at a time in the list box window.
  • the shape control in the inventive development environment draws only rectangles.
  • the FillStyle property is available for configuration.
  • a Timer control can execute code at regular intervals by causing a Timer event to occur.
  • a timer control behaves like a "countdown" timer: It waits for the number of seconds specified in the Interval property then executes the code under the timer event. The countdown occurs only once. Displaying a sequence of screens is an example of this timer's usefulness.
  • the Interval property is configurable.
  • the development software 11231b adds two controls not found in Visual Basic to the development-software environment: SigControl and MSRControl .
  • SigControl allows developers to put a signature-capture box on an iPOS device 120 and to manipulate signature information.
  • the signature capture control has three configurable properties: BorderStyle, MaxSize ad Timeout.
  • BorderStyle allows a developer to set the border style for the control.
  • MaxSize limits the number of points collected per signature. Once the signer produces MaxSize pixels, the iPOS terminal 120 stops taking signature data.
  • the Timeout property sets the number of seconds following the user's lifting the pen from the iPOS terminal 120 and before a SigTimer event occurs.
  • the magnetic strip control enables an iPOS terminal 120 to read magnetic strips on credit, debit, loyalty and like cards.
  • MSRControl activates a magnetic strip reader to capture the information.
  • a magnetic strip control may be invisible on the iPOS device 120 but visible nonetheless on the developer's screen on the host 110.
  • the magnetic- strip reader also activates. Once active, the MSR can accept information from cards. If a good swipe occurs, any code under the GoodSwipe event is executed.
  • the magnetic strip control has no configurable properties.
  • a developer constructs an unconventional program and compiles it into a script using a DLL associated with the development software 11231b.
  • a script Once a script is developed and compiled (or otherwise made resident) on a host 110, a developer may download the script into an iPOS device 120 by means of the communications link 130.
  • the iPOS device 120 stores the script in nonvolatile memory.
  • the host 110 and the device 120 may by design work substantially asynchronously, exchanging commands and other communications through the link 130. - COMMUNICATIONS
  • GoToLabel has the following syntax:
  • Label Name may be a routine name.
  • the iPOS device 120 transfers the flow of execution to the parameter LabelName.
  • the SetVar command has the following syntax:
  • VarName is a variable name and StringValue is a string.
  • SetVar enables a host 110 to set a string variable on the device 120. For example, a host 110 might set a variable named. "Date” to "12/01/1999" as follows:
  • the GetVar commands has the following syntax:
  • VariableNa e is a variable name and GetVarO returns a string.
  • GetVarO corresponds to SetVar in that the former enables a host 110 to retrieve a string value from an iPOS device 120. For example, if the script variable, "CreditCardNumber" holds credit-card data from an MSR read event, the host 110 may request that variable information from the script by issuing the following GetVar command:
  • the host 110 may read or write any text variable in a script on the device 120, using GetVarO and SetVarO. The host 110 initiates these exchanges of information. The device 120 does not itself invoke SetVarO or GetVarO.
  • VB mode the visual programming environment highly parallels the iPOS environment.
  • the application eventually produced replicates on the iPOS device 120 the objects and their appearance on host forms (with the exception of those intentionally hidden). Both the host 110 and the iPOS device 120 operate from the same software 1123. Program responses triggered by actions at the hosts closely match the programs responses triggered by actions at the iPOS device 120.
  • Honing an iPOS application proceeds quickly. As soon as the host 110 runs the application generated by the development software 11231b, the form appears on the iPOS device 120. The close coupling of the host 110 and iPOS device 120 effects a responsive interface that keeps clear the cause-and-effect relationships between application changes and application performance. Because the development host 110 can run the VB-mode application, a developer can test aspects of the application without having access to an actual iPOS device 120. To test a VB-mode application, the developer sets the development software 1123 into test mode. The different modes enable the developer to place application logic where it is most appropriate -- either on a host or on the iPOS terminal itself. That flexibility allows a developer to create transactions applications for practically any hardware and software configurations.
  • the development software 11231b uses unchanged the following controls: check boxes, command buttons, images, labels, lines and list boxes. Their appearance and behavior are the same as in a conventional Visual Basic environment. Accordingly, each of these is described summarily below.
  • the software 11231b modifies the behavior of the following pre-existing Visual Basic controls: shapes and timers. Each of these controls, along with new, added controls, is described in turn below.
  • the behavior of the check box control tracks the behavior of that control in Visual Basic. All of the following standard properties are available: Alignment, Appearance, BackColor, ForeColor, Caption, Enabled, Font, FontBold. Fontltalic, FontSt ikethru, FontUnderline. FontName, FontSize, Height, Width, Left. Top, Name, Style, Value, and Visible.
  • the size of an image on a device 120 stretches to fit the size of the image control.
  • the image may be in any Visual Basic- ) compatible format.
  • the properties of an image control are the same as in a standard Visual Basic environment.
  • an iPOS device 120 may store an image in its non-volatile memory. This way, the images appear faster, not being transmitted with each display.
  • the behavior of the label control tracks the behavior of that control in Visual Basic -- including the wrapping of words. All of the standard properties are available.
  • the behavior of the line control tracks the behavior of that control in Visual Basic. All of the standard properties are available.
  • the behavior of the list box control tracks the behavior of that control in Visual Basic. All of the standard properties are available.
