In the previous example we showed how to send data from
the Wedge to a DOS application by first sending the data
as keystrokes to the NotePad program and then cutting the
data out of NotePad, switching the focus to a DOS window
and pasting the data in. You can use the same technique to
have the Wedge send data to two (or more) Windows or DOS
programs at a time. For example, if in the previous example
we were to copy the data from NotePad instead of cutting
the data, we would end up with both the NotePad and the DOS
programs receiving the data.
All you need to do to pass data to two Windows programs
is to send the data to the first application and then use
whatever keystrokes are necessary to copy the data to the
clipboard, switch the focus to the second application and
finally paste the data in. Even if neither of the applications
provides an explicit copy or paste function, you can always
copy text to the clipboard in any Windows program by first
selecting the text and issuing the keystroke Ctrl+Insert
(or Ctrl+C). In a "Field Postamble Keystroke" macro
in the Wedge, Ctrl+Insert is represented by: ^{INSERT}. Likewise,
you can paste text data from the clipboard into any Windows
program using the keystrokes Shift+Insert (or Ctrl+V). In
the Wedge Shift+Insert is represented by: +{INSERT}. To select
text in any program you can hold down the shift key while
using the arrow keys, Home, End, Page Up and Page Down keys
to highlight and select characters.
Windows will also switch the focus between all running application
when you hold the Alt key down and press the Tab key. Windows
maintains a list of all currently running applications with
the application that currently has the input focus placed
at the top of the list. If you switch to another application,
the new application moves to the top of the list and the
previously active application moves down one spot in the
list. When hold the ALT key down, each time you press the
tab key, Windows moves down the list one item and selects
the application at that position in the list. When you release
the Alt key, the selected application is given the focus
and is moved to the top of the list pushing all other application
that were above it in the list down one spot.
For example, if you had the Wedge set up to send keystrokes
to NotePad and you also wanted to send the data to the WordPad
you could use the following procedure:
Set up the Wedge in "Send Keystrokes" mode specifying
the NotePad program as the target for all keystrokes from
the Wedge. Next, configure the Wedge to work with your serial
device and then add the following characters to the end of
the "Field Postamble Keystrokes" for the very last
data field that you have defined in the Wedge:
+({LEFT}{HOME})^{INSERT}{DOWN}%{TAB}+{INSERT}
Activate the Wedge and then launch the WordPad program followed
by the NotePad program. At this point NotePad has the focus
and is therefore at the top of the Window list with the WordPad
program directly underneath it. When you input data from
your device, it will be sent to both NotePad and WordPad.
The keystrokes: +({LEFT}{HOME}) means hold the shift key
while pressing the left arrow and the home key. This selects
all text in the current line. The keystrokes: ^{INSERT} means
Ctrl+Insert and causes all selected text to be copied to
the clipboard. The {DOWN} keystroke that follows is there
to simply de-select the currently selected text. The keystrokes:
%{TAB} means Alt-Tab and causes Windows to switch the focus
to the WordPad program. Finally, the keystrokes: +{INSERT}
means shift+insert and performs the job of pasting the data
from the clipboard into the WordPad program.
To send the data to three Windows programs at a time you
could use the following "Field Postamble Keystrokes":
+({LEFT}{HOME})^{INSERT}{DOWN}%{TAB}+{INSERT}%{TAB
2}+{INSERT}
