CPRS Versions

This table will list links for the various CPRS versions. (The most current version is at the top)

version change trick

NB: There is a trick to making version 1.0.26.68. It is done for you in CPRSDir.zip which can be found along with the instructions for creating it at:

http://downloads.opensourcevista.net/VADemo9-26-06

To find out which version to use, look next to the option named "OR CPRS GUI CHART" like this example where CPRS version 1.0.23.15 was needed:

D Q^DI

VA FileMan 22.0
Select OPTION: 5  INQUIRE TO FILE ENTRIES

OUTPUT FROM WHAT FILE: DEVICE// OPTION
1   OPTION                           (10126 entries)
2   OPTION SCHEDULING                (116 entries)
CHOOSE 1-2: 1  OPTION                     (10126 entries)
Select OPTION NAME: OR CPRS GUI CHART       CPRSChart version 1.0.23.15
ANOTHER ONE: 

To use a particular version of CPRS, the server-side software code must match. The files are found at ftp.va.gov/vista/Software/Packages/Order Entry-Results Reporting - OR/ and the source code is in the "Programs" subdirectory of this directory

Thus:

ftp://ftp.va.gov/vista/Software/Packages/Order Entry-Results Reporting - OR/

The Delphi source code for each of these (e.g. OR_30_235_SRC.ZIP) will be found in the subdirectory ...Packages/Order Entry-Results Reporting - OR/Programs/

The wget(1) utility is capable of fetching the files from this server

AceFTP is a freeware FTP program that works, if needed http://software.visicommedia.com/en/productsfreeware/

(In the past this FTP site could not be reached with Mozilla/Firefox. That has been corrected.)

1.0.26.69 (and TMG-CPRS) spoof --> 1.0.26.76

Since the changes between 1.0.26.69 and 1.0.26.76 are relatively minor, in this case, version can be used by changing the option in the option file like this:

 D P^DI

 VA FileMan 22.0

 Select OPTION: 1  ENTER OR EDIT FILE ENTRIES

 INPUT TO WHAT FILE: OPTION//
 EDIT WHICH FIELD: ALL//

 Select OPTION NAME: OR CPRS GUI CHART       CPRSChart version 1.0.26.76
 NAME: OR CPRS GUI CHART//
 MENU TEXT: CPRSChart version 1.0.26.76  Replace 76 With 69
   Replace
    CPRSChart version 1.0.26.69

When using TMG-CPRS, another way of reaching the exact same result is to add "SPOOF-VER=1.0.26.76" to the end of the Windows shortcut to CPRS like so:

... S=192.168.xxx.xxx P=92xx CCOW=DISABLE SPOOF-VER=1.0.26.76

(This method has the (admittedly dubious) advantage of allowing both a CPRS v1.0.26.68 and a v1.0.26.76 to connect without changing the server side.

Caution: One needs to know that the two versions truly are compatible or be willing to risk nasty side-effects, perhaps even damage to the server's database.

SSH Tunnel

Communications between CPRS and the VistA server are not encrypted by default. Access/Verify Codes and all patient data are transmitted in the clear. However, these can be protected by setting up an encrypted "tunnel" between client and server.

Automatic Windows Installer

The Astronaut suite of automatic installers includes cprs, tmg-cprs and many other clients, available in point-click windows .exe installers. IP address and port number are entered by the user.
