* This document provides the introduction note for the VEE 3.0 release in early 1995.
* As of February 1, 1995, HP VXD is introducing the latest version of the VEE
programming language. The 3.0 release of VEE brings VEE up to date across
all platforms -- UNIX(tm) on S300, S700, and Sun workstations, and Windows on
personal computers -- and includes extensive user-interface enhancements.
Changes include:
One thing that the new version does not provide is Plug-&-Play driver
capability; this is because the PnP spec is still being refined. A minor
revision of VEE will be introduced later when the spec solidifies.
* The new VEE user interface is derived from the old -- that is, it isn't a
complete rewrite -- but it has been extensively modernized ... for example,
all objects have a more MS-Windows-like cosmetic appearance and operation
(adding resize borders so you can change the shape of an object with a
click-and-drag mouse operation, instead of having to select a menu pick as
with previous versions of VEE).
A particular enhancement has been to allow the user to perform VEE
configurations interactively that required modifying the VEE.INI file. This
is done (primarily) through the "Edit Default Preferences" entry in the VEE
"Files" menu; click on this, and you get a dialog box that resembles a tabbed
folder:
This panel of the dialog provides essentially the same option settings as
provided by the older "Preferences" menu entry, if in a more concise form.
However, you can use the "Colors" panel to set colors for various elements on
the VEE display:
The "Screen Element" box provides a pull-down list of the various screen
elements available; the "Color Value" button pops up a dialog with a palette
to allow you to select the desired color for that element. You can also set
fonts using the "Fonts" panel:
Again, you can select the "Screen Element" with a pull-down list, and set the
"Font Value" with a dialog box ... the dialog allows you to set font type,
style (normal, bold, or italic), and font size -- and provides you with a
preview sample to allow you to find out if it's a proportional font and so
on.
The "Number" panel also provides options settings previously obtained through
the "Preferences" menu:
Finally, the "Printing" panel allows you to specify the grayscale level of
elements of a VEE program according to your particular preferences:
Note that if you refer back to the "General" tab panel in this folder, there
is an entry called "Save Default Colors/Fonts with Program". This allows you
to define a color scheme and then distribute it with your VEE program to
other VEE installations.
This "tab folder" approach is now used for configuring all objects; in
general, you can set fonts, colors, icon, and specific properties for that
specific instance of an object using the tab folder.
* Other general user-interface changes include:
* User-interface objects have been enhanced in the following categories:
* The Toggle button has been generalized to allow it to represent virtually
any kind of two-position switch; you can not only select from a variety of
useful predefined appearances -- a simple button or check box (its only
appearances in previous versions), or Paddle, Rocker, or Slide switches in
both vertical and horizontal orientations -- but you can make a custom switch
by providing it with two bitmaps, one for the "on" state and one for the
"off".
If you select one of the predefined Toggle objects, pull down its object
menu, and select its "Edit Properties" menu, you get a tab folder:
Most of the stuff is more-or-less typical of any object menu -- Colors,
Fonts, and Icon settings, fields for setting debugging, option, and layout
options -- but there are a few special fields in this case. First, you can
set the Toggle to "Wait for Input" -- in which case the Toggle will not
generate an output until you actually click on it with a mouse. (This new
feature applies to all "auto-execute" objects.)
Second, you can select the Toggle style -- Button, Check Box, Paddle, and so
on -- which is no big deal since you have access to the different styles from
the VEE menu ... except for the "<Custom>" entry, which allows you to build
your own Toggle style. Click on this and then select the "Custom" tab in the
tab folder and you get:
This panel allows you to select and preview a pair of bitmap files that will
be alternately displayed in the Toggle in its On and Off states. The files
can be GIF, Windows BMP, or X11 ICN files.
* Previous versions of VEE had a single indicator object -- the Meter; VEE
3.0 provides minor enhancements for this object, such as choice between
horizontal or vertical orientation, with the options set by the following
dialog box:
Unlike the earlier implementation of the Meter object, you not only can set
the orientation (and turn off the digital display if you want it to update
faster) but you can also select the colors for each of the ranges; click on
the defined color on the dialog and you get a dialog to allow you to select
the color.
You can programmatically set the Min or Max values of the Meter object; the
other attributes are not programmable.
The Meter object was the only indicator object available in previous versions
of VEE; VEE 3.0 adds four more: FillBar, Thermometer, Tank, and ColorAlarm.
The FillBar is a simple bar indicator that can be set to provide different
colors for three ranges; the Thermometer is just a FillBar with a bulb on the
bottom, and the Tank is a fat FillBar. All of them use the same
configuration dialog to set their properties, which is similar to that for
the Meter:
The major difference is that the range bounds on these three objects are
single-ended, while for the Meter there are bounds on both the negative and
positive extents of each range. You can set the Min and Max values as well
as the High and Low limits programmatically; the other attributes are not
programmable.
The ColorAlarm provides essentially an "LED indicator" that changes color
(and optionally provides a different text prompt) when the input value
crosses into a particular range; it can have a circular or square appearance.
The configuration dialog is similar to that of the FillBar except that it
allows setting text values for each range and provides different layout
options:
You can programmatically set the High, Mid, and Low limits and text on the
Color Alarm object; the other attributes are not programmable.
* The Enum object has also had a facelift in VEE 3.0. In earlier versions,
VEE had a single Enum object that could be configured to as a set of "radio
buttons", a cyclic list, or simple list. This usage was obscure so the Enum
object was renamed as a "Selection Control" and the menu now provides a list
for each different configuration: Radio Buttons, Cyclic Button, List, and
two new variations -- Drop-Down List and Pop-Up List, which act pretty much
as their names imply.
* Two new objects, the Label and Picture objects, help you to build cleaner
user interfaces.
The Label object is much like a Text Constant object; it allows you to
display a string of text. The distinction is that when you merge a Label
object to your Panel View, it doesn't show a border -- the text appears as
part of the Panel View.
While you could integrate bitmaps into earlier versions of VEE, they could
not be loaded by a program at run-time; you had to integrate them into the
program ahead of time. The new Picture object allows a program to load
bitmaps at run-time, as well as stretch, size, and tile them.
There's not much to it ... all the properties are set by the Picture object
tab folder:
You can bring out pins to clear the Picture object or load a new bitmap.
GIF, X11 icon, and Windows BMP files are supported.
* While you could build popup dialogs in earlier versions of VEE, assembling
a dialog by hand was a pain and something better was needed. VEE 3.0 allows
you to invoke predefined pop-up dialogs that provide most of input
functionality that a VEE user requires -- including the ability to browse
through the file system to select files, a capability that was sorely needed
in earlier versions of VEE:
The Message Box allows you to pop up standard Windows-style alert dialogs;
it is configured with an object with the format:
This object allows you to provide:
The message, symbol, and default button can be set programmatically by
bringing out input pins to the object. You can also use the object's "Edit
Properties" tab folder dialog to set colors, fonts, and a timeout; setting a
timeout adds another output pin. When the object is pinged by a program, it
pops up a dialog formatted as specified.
The Text Input, Integer Input, and Real Input dialogs are controlled by
objects with some general similarities to the Message box:
The List Box object allows you to pop up a dialog with a list:
The input fields allow you to specify the list, the default entry from the
list, and whether to allow multiple selections from the list; the output
consists of the text and array index of the selection (if multiselection has
been set, these are both arrays) or a cancel output. You can specify the
list array and the index of the default selection as inputs. The "Edit
Properties" tab folder allows you to select the number of items to be
displayed before the list requires scrolling, a timeout, and custom button
labels.
Finally, the File Name Selection box allows you to give the user a standard
file browser and get a file name back:
You can specify a prompt, the initial directory, a wildcard pattern, and
select for reading or writing; all these features are programmable. The
dialog returns a filename or generates a cancel output.
* VEE 3.0 allows a user to control a VEE program from the keyboard. Programs
can be run and controlled via the following control key sequences:
You can use the Tab key to move around a user interface, skipping from input
object to input object; Shift-Tab moves you backwards. You can select a
button by pressing the space bar.
The most useful element for building such a user interface is the OK button;
not only is its operation more straightforward than other input devices, but
it has a special feature that make it suited to the role: you can assign an
OK button to a function key, the Enter key, or the Escape key.
You can configure this feature by bringing up the OK button's object menu:
You set the appropriate flags to assign a function key, the Enter key, or the
Escape key to the button; note that you could in principal assign a function
key, the Enter key, and Escape key to the same OK button, though all three
don't make much sense; generally you want to assign the Enter key to one (and
only one) "default" button (possibly also mapped to a function key), and
assign the Escape key to some "emergency" button (also possible mapped to a
function key.
The following program demonstrates how to use keyboard input through a set of
OK buttons; all it does is allow you to press buttons and get a different
text output in an AlphaNumeric display object:
All objects whose type is not obvious in the above diagram have their types
listed to the left of the object. The four OK buttons are assigned keys as
follows:
A panel view for the program can be set up as follows:
You can press CTRL-G to run the program, use Tab and Shift-Tab to move among
the OK buttons, and select a function with the Space bar. You can select any
of the three buttons at top by pressing the appropriate function key; note
that F3 selects the "GetVal" function, which pops up a Dialog box to get a
numeric input ... you can navigate through the fields of the Dialog box with
Tab / Shift-Tab and select a button with the Space bar, just as you do with
the rest of the user interface.
If you press Enter, you get the default button, which is "[F1: TEST1]"; if
you press the Escape key, you quit the program.
It is recommended that the OK buttons and dialog boxes be used to set up the
keyboard-controlled user interface; other input devices can be used, but
suffer from a number of limitations:
It is not recommended that you set up multiple threads in programs
designed for keyboard control! They can be made to work but getting them to
do so is counterproductively tricky.
* There are several significant I/O enhancements in VEE 3.0:
* One of the most useful VEE 3.0 features is the Multidevice Direct I/O
object; this enhances the earlier Direct I/O object by allowing a single
transaction object to communicate with multiple instruments.
The Multidevice Direct I/O object looks much like a Direct I/O object until
you try to specify a transaction; then you get a dialog like this:
You can click on the instrument field to select another instrument from those
you have configured under VEE:
You can also specify a different address in a transaction if you like:
Once you have set up transactions they take the form:
* Workstation-based versions of VEE now support interprocess communication
(IPC) through a new transaction object named To/From Socket. (PC VEE will
not support this until after Windows95 is introduced.)
A "socket" is a network connection and is much more convenient than the
named-pipe scheme used for IPC in previous versions of VEE. In general
terms, it makes a networking connection between two different machines look
just like a file, with communications taking place between a "caller" program
and a "receiver" program. (Windows users will find the scheme similar to
DDE, though sockets are a much more reliable mechanism.)
Socket communications require that the receiver has selected a "port number"
-- a more or less arbitrary value in the range of 0 to 65,535 -- through
which it can be accessed and is waiting to accept a remote connection. The
caller will then try to connect to the receiver through through the
receiver's Internet address and the socket number.
Note that I said that port numbers are "more or less arbitrary" ... the
reservation in that statement refers to the fact that port numbers between 0
and 1023 are reserved for the operating system, and port numbers from 1023 to
5000 are reserved for commercial purposes. Port numbers above 5000 are open
for general use; ports above 5000 are referred to as "transient".
The To/From Socket object allows you to configure both ends of the socket
connection; for example, consider transferring a string from an arbitrary
caller to a receiver on a host named "hpislmmc" that has bound itself to port
number 5001:
The To/From Socket object allows you specify whether you want to connect to a
port (from a caller) or to bind to a port (on a receiver) and specify a
transaction timeout as well. Note that there is an EXECUTE transaction that
allows you to specifically terminate a connection.
Remember that when you do a "Bind Port" that your VEE program will hang on
that object and wait for something to happen (at least for the timeout
interval).
* Other I/O enhancements include:
This feature was added mainly to provide a soft-front-panels product for
some of our partners -- VEE can be run in dedicated ID Monitor mode by
invoking it as "vee -idmonitor" -- and this capability is documented in
the main VEE release on the assumption that some users may find it handy.
Since LAN devices are mutual access, and VEE only maintains a lock on an
interface on an object-by-object basis, there is a possibility that
another network client might interrupt the transaction with the LAN/HPIB
server. Because of this, the Interface Operations object now allows you
do an indefinite lock on a LAN/HPIB server with a new EXECUTE LOCK
transaction; there is also a new matching EXECUTE UNLOCK transaction to
allow release of the lock.
* The following minor enhancements have been added in VEE 3.0:
The major purpose for this function was to allow operator output under
Sequencer test runs ... under previous versions of VEE you couldn't get
any output from Sequencer tests until the entire test run completed, and
we got complaints about it.
These functions allow such output. You create a UserFunction with a panel
view to provide display output -- named, say, "Disp()", which displays a
single item on an Alphanumeric display -- and then your test functions can
display this panel by invoking: showPanel("Disp")
Once it is visible, test functions can display data in the panel by
invoking that UserFunction: Disp("This is a test!")
The panel will go away at the end of the program or when a test function
uses "hidePanel()" to conceal it.
* The following bugs were fixed in 3.0 VEE:
Another bug showed up in that you can set an input pin on the Sequencer to
dictate which test is run; the odd effect of it is that it disables
logging output. There is now a "Data In" pin that gets around this
problem.
What happened was that if the chunk of VEE program that the On Cycle is
driving completes in less than one PC clock tick (1/18.2 seconds), then
the On Cycle isn't smart enough to realize that it's already done
something in that clock tick, so it does it again. This has been fixed.
Instrument Finder won't find any instruments on an NI AT-GPIB / TNT card
(which works fine otherwise); this fix has been folded in as well.
By default a popup is secured when it's popped up and then unsecured after
it goes back down; this prevents people from messing with it at runtime.
If you pause the program and then save it, the popup will be stored in
this state. VEE 3.0 revised the way pauses are dealt with and eliminates
this.

They're a little simpler to configure -- you can specify a prompt, a default
value, a value constraint, and an error message (all these values are
programmable); they return a value unless the user cancels the dialog or it
times out. The "Edit Properties" object tab folder allows you to specify a
timeout, change the button labels (the default values are "OK" and "Cancel"),
and specify "password masking", which prevents the input from being displayed
as it is typed in.
