Actually, in this case LPT stands for Log Plot (if itâ€™s from the Phase Noise personality).Â Transfer it to your PC on a floppy and then youâ€™ll need to download a converter from the Agilent website.Â If you search for â€œCSV LPTâ€ on the website youâ€™ll hit a FAQ that references the converter.Â This executable will turn it into a CSV excel file.

Subject: [vrf] Viewing a .LPT from a 4440A PSA spectrum analyzer

Â

I have a trace plot from an 4440A PSA spectrum analyzer. It is saved as a .LPT file.

Does anyone have any information on how I can view and print this out on a computer?

Hello all,

Can anyone tell me if there is a way to call a UserObject or UserFunction upon 'abnormal' exit of a Vee program. I require to set instrument outputs to zero and close certain applications that I have opened using ActiveX. If the user selects to end the program using the provided exit button this is possible however how can I perform this if they close the application using the 'X' ? Is it possible at all if the program hangs or is closed from task manager ?

Thanks,

Victor

Probably not from within VEE or from within any program, BUT
it should be very doable from within the calling environment.
that is, start your VEE program from with a shell script or
another running program or any such environment. This script
launches VEE and waits for a successful exit ( have VEE return
a message like "0" on proper exit ). If anything goes amiss
reset your instruments.

You can catch the close box, but you have to subclass the VEE window.

> hangs or is closed from task manager?

You can catch any message sent by Windows. If an application calls ExitWindowsEx with the EWX_FORCE bit set you can't catch that. IIRC this was changed in XP though: all applications are at least sent WM_ENDSESSION even though the OS doesn't honor requests not to end if applications return FALSE.

Also, I think there's no defense against TerminateProcess but I could be wrong about that now too (I think that also changed for XP).

If the program hangs there's nothing anybody can do about that. If VEE's message queue is not managed for a certain amount of time it will be marked as Not Responding. If it doesn't respond to WM_CLOSE then Task Manager will offer the option of using TerminateProcess, in which case VEE will be conveniently nuked with no mercy. In this case, TM will always try WM_CLOSE first.

I can send info on how to do all this to you shortly - in about an hour I think. It's all in The Archive but it's closed at the moment for disk fixing.
