Small GUI tweaks and bug fixes.

When the amount of data is too large, the software will become very slow. Is there any way to improve this?

Is this the CSV...?
Certainly loading from the CSV to the Playback Chart can be slow if the CSV is big........but where exactly are you seeing it becoming slow?

Depending on where/how you are seeing this there are likely some changes I can make.

Ian.

[wutieru]

yes，
When I load a CSV file with over 60000 records, the playback interface becomes very slow,requiring a wait of about 15 minutes or more.
If I modify temperature parameters on the playback interface, the loading process will repeat again, with a wait time of over 15 minutes.

I've reported before that the calculation of the Y axis values automatically during loading is very slow. Turning it off makes all the difference.

Reading a CSV into the Playback Chart is significantly faster, especially large CSV's.
If you can please time the previous version before you upgrade/after upgrade and post here CSV size (No. lines) and time.

My examples as follows:

10000 line CSV:
Old code = 5secs
New code = 0.5sec

62000 line CSV:
New code = 2secs

251000 line CSV:
New code = 7secs
(PS. My new PC is fast)

I have left the previous version available for download as this one is in beta for the moment as there are quite a few code changes!........It seem ok though, but there's more I can do to optimize the code further.

Further mods to the Playback Chart to increase loading speed.
Enabling TEMP and HUM via checkboxes is now faster also.
In order to achieve this I have removed the Manual Refresh button and Auto-Refresh (5ecs) check box. If you want to refresh the chart then just open the CSV manually again.

EDIT V3.220: Turning off PPM, TEMP & HUM via check boxes on Playback Chart is now much faster.

Playback Chart, fixed small bug with the ZOOM ALL button.
This has highlighted another issue so I will need to go over these ZOOM buttons in the coming days, but for now they work ok.

Thanks，
The Playback runs very fast now.

Very minor mods to some of the text labels on some of the tabs, i.e. 3245A Cal tab now says "3245A CALIBRATION ADJUSTMENTS" & PDVS2mini tab now says "CALIBRATION / ADJ.".
This is because strictly speaking "calibration" is NOT making adjustments, it is purely recording against a standard.

I also fixed some compilation warnings in the source code.

Ian.

[IanJ]

The source code has been moved from my own server to Github which makes it easier for me to deploy the source after any changes, i.e. direct from Visual Studio.

You need all 3 repositories:
WinGPIBproj - Visual Studio project (the main GUI).
IODevices - Visual Studio project (the DLL required by the main app).
WinGPIBadditionalinfo - A compilation of files, datasheets, sample data, utilities, 3rd party DLL's & drivers etc.

Great to hear Ian - Thanks for all the work you've done here.

Hey Ian,

Is the reference to "VISA-COM 5.14 Type Library" (VisaComLib) in WinGPIBProj just an artifact? I removed it from the solution rather than recreate an x86 build project and things seem to work fine without it. You use a DLLImport in IODevices to access the Visa DLL so I don't think it is used but wanted to check in first.

Thanks,

TonyG

I never added that manually, so wonder if it was detected as a dependancy when I upgraded my Keysight VISA drivers some time ago (couple years ago!) and subsequently loaded up VS.
It doesn't appear present in some very old code I looked at.

It's a helper DLL to assist in VISA comms apparently but I don't think WinGPIB needs it as it directly accesses the Visa32.dll.

Looks like WinGPIB is ok without it from testing.

Ian.
