05 May 2023
AT dotNET Server V4.2.8494

Fixed occasionally getting TCP client error messages.

Menu labelling  - change "report" to be "Report (Local DB)" for clearer understanding - this feature is not available for your own external DB.
Add Ability to print individual historical local DB Results sheets from the localDB screen.
Printing - Right  justify the max, min, result data on both live and localDB  historical results, and units separate too, so numbers line up for ease of reading..
On install update control panel icon looks like the V3 icon.


22 Mar 2023
AT dotNET Server V4.1.8473

Menu labelling
Change "report" to be "Report (Local DB)" for clearer understanding that the build in report generator only looks to the local DB on the PC, not to any external DB you may also have enabled.

SQL – tblVoltechTestID.TestUnits
Fixed missing SQL data for R test 
SQL tables created by V3 of the server used “varchar(x)” which only supported ASCII.
SQL tables created by V4 of the server have always used nvarchar(x) which supports UNICODE.
As V4 now uses the “Ω” symbol rather than “ohms” this meant that users connecting V4 server to older legacy SQL databases would have missing entries on tblVoltechTestID.
This update now performs a silent test on any connect SQL database and updates the data types from "varchar" to "nvarchar" silently.


10 Feb 2023
AT dotNET Server v4.1.8440

Results - add 4th optional results option "TSV" to make TAB separated values file, (as TXT); this allows easier use in EUR where comma is delimiter.
Default on first install for this is OFF
Use SYSTEM CULTURE for Dates/Time and numeric format (e.g. comma for decimal in Europe).

File output - add two more file name options so BATCH is visible in file name if used
<Date>_<Batch #>_<UnitSN>
<Date>_<Batch #>_<PartNumber>_<UnitSN>.

Fixed printing- previously was always in TAB 1, but now printing is the active selected tab.

Fixed Server crashed when some REGION settings used.
Fixed unhandled exception rather than crashing silently.
Fixed Server silently fails on run.
Added more proactive checks server if unable to start properly.

17 Aug 2022
