Hi Richard and Mark
I also tested the PicoLog program, which gives the same kind of errors as my C program. But the PicoScope still works fine!
In addition I also made a test with a call using adc100_get_times_and_values
instead of just a single reading. This STILL gives the same problem.
Win-98 + ADC-101: all programs works
Win-XP and a parallel port + ADC-101: PicoScope works BUT not PicoLog, Excel fil, C++ code, C code...................
Win-XP and a USB->Parallel port adaptor + ADC-101: all programs works
So even though you previously wrote that PicoScope only manipulates the parallel port by calling the dll, it must somehow do things differently from the PicoLog and C,VB,C++ code.
Are you sure that the program doesn't make some kind of initialisation of the parallel port?????
Have a nice weekend
