Note: DDE commands will only execute if WinWedge has been
activated.
There are two ways to issue DDE commands to the Wedge: either by issuing them
directly from another application's macro or programming language or you can
establish a "Command Source DDE Link" between another application
and the Wedge and then issue commands by entering the command in the DDE Command
source location (a cell in a spreadsheet for example).
[Command] Function
1.[APPEXIT] Exits WinWedge.
2.[APPMINIMIZE] Minimizes WinWedge Window.
3.[APPNORMAL] Opens WinWedge Window.
4.[BEEP] Causes WinWedge to Beep once.
5.[BREAK] Issues a Serial Break signal.
6.[CLEAR] Clears all input data fields in WinWedge Window.
7.[COPYFIELD(n)] Copies the data field "n" into
the Windows clipboard.
8.[COPYDATE] Copies the date/time display field into the
clipboard.
9.[COPYRECNUM] Copies the record number display field into
the clipboard.
10.[SUSPEND] Suspends WinWedge.
11.[RESUME1] Resumes WinWedge for one data record.
12.[RESUME] Resumes WinWedge.
13.[RESET] Flushes all buffers and resets WinWedge.
14.[RTS=ON] Sets the serial port RTS line on.
15.[RTS=OFF] Sets the serial port RTS line off.
16.[DTR=ON] Sets the serial port DTR line on.
17.[DTR=OFF] Sets the serial port DTR line off.
18.[TOGGLEDTR] Toggles the serial port DTR line for 100
ms.
19.[SEND(text)] Sends the text in parentheses out the serial
port.
20.[SENDCODE(n)] Sends the character with ASCII code "n" out
the serial port.
21.[SENDDATE(format)] Sends the date or time out the serial
port using a specified Date/Time format string.
22.[SENDFILE(filename)] Sends the contents of the specified
file out the serial port.
23.[SENDOUT('text',n...)] Sends text and control codes out
the serial port. Text must be supplied as quoted strings
using single quotes and control codes must be supplied as
ASCII values. Text and control codes may be combined in any
combination with individual elements separated by commas.
Ex. [SENDOUT('Test',13,10)] sends the word Test followed
by a carriage return (ASCII 13) and a line feed (ASCII 10).
24.[PUSH(button caption)] Pushes a button in WinWedge Window.
The button is specified using its caption. The specified
caption should be the same as that entered when it was originally
defined including ampersands.
25.[CONFIG(filename)] Reconfigures the Software Wedge. "filename" specifies
the configuration file to use and must include the filename
extension and the full drive and directory path if it is
not in the current directory. You may not specify a configuration
that uses a different serial port than the one currently
in use.
26.[STRIPCRLF-ON] Enables / Disables stripping carriage
return - linefeeds
27.[STRIPCRLF-OFF] from data supplied through an Output
Buffer DDE Link.
28.[TIMER-ON] Enables / Disables sending of timed automatic
output
29.[TIMER-OFF] strings.
30.[TIMERINTERVAL=n] Changes the timing interval (ms) for
timed automatic output strings to the value n (between 1
and 9,999,999).
31.[PASTE-COMMAND] Pastes a DDE Command Link using data
in the clipboard.
32.[REFRESH-COMMAND] Refreshes the last DDE Command Link
defined.
33.[TERMINATE-COMMAND] Terminates any active DDE Command
Link .
34.[PASTE-BUFFER] Pastes an Output Buffer Link using data
in the clipboard.
35.[REFRESH-BUFFER] Refreshes the last Output Buffer DDE
Link defined.
36.[TERMINATE-BUFFER] Terminates any active Output Buffer
DDE Link.
Note: All DDE commands must be enclosed in square brackets.
When sending DDE commands to the Wedge from another program, use the DDE Application
Name "WinWedge" and the DDE Topic "COMn" where "n" is
the number of the serial port that WinWedge is installed for. A DDE Item is
not required when sending DDE commands to the Wedge.
Note: WinWedge does not have to be in "DDE Server Mode" in order
to accept and process DDE commands. The Wedge will still execute any DDE commands
sent to it even if it is in "Send Keystrokes Mode" or "Log To
Disk Mode".
To send any of the Commands from a VBA subroutine, use the
syntax:
| |
Sub
SendDDECommand () '
This function unloads the Wedge from memory
'
initiate DDE channel with wedge on COM1
chan = DDEInitiate("WinWedge", "Com1")
'
send DDE command to Wedge
DDEExecute chan, "[AppExit]"
'
close the DDE Channel
DDETerminate chan
End Sub
