For the purposes of obtaining support from ITIM Technology solutions it is important that you can readily identify the version all the DP4 files issued as part of an application.
Systems developed over a period of time may often use components from several different releases of DP4. Don't assume that because one particular file has a certain version number, that all the other DP4 files will be from the same version - DP4 is usually very forgiving when files from different releases are used in the same system. Always get as much version information as you can from the machine where a problem is occurring (and from both client and server machines where networking is involved).
DP4 provides several facilities that allow you to view version information in a consistent way across all the standard DP4 components:
You can use the PROGDATE utility to view and save to file program version information.
From release 4.621 DP4 includes a batch file named DP4VER.BAT that will quickly display the version information for all installed DP4 executable files. The information is saved in a file named version.prn. If you require support from Itim Technology Solutions on a DP4 related problem, sending this file as part of the problem report will often help get your problem resolved more quickly. The contents of DP4VER.BAT are shown below:
dir /a-d /b >xx *.exe *.dll *.w32 del version.prn progdate -full -read xx -file .\version.prn view version.prn
From 4.620, if DP4 error logging is turned on, and the debug_version is 1, the DP4 version of all components in use is written to the errog log window and the debug.out file. Earlier releases of DP4 also report some version information, but this is not always reliable.
On most version of Microsoft Windows, you can check the version information of Windows DP4 Executables by right clicking on the file in Explorer and choosing Properties. The Version Tab will display the DP4 version information.
