ViSession instrument object handle gets converted to unsigned int

[SIten]

In executable mode the instruments handle is passed around the functions in a string state in (view variable window)

The commands work.

When packaged to a dll. the instrument handle is created, but when it is passed to the next function call it is changed to an unsigned int and i get a general protection error.

The function will not work.

RSPD3303C_err = RSPD3303C_Init ("USB0::0x0483::0x7540::NPD3ECAD2R0396::INSTR",&RSPD3303C_obj) ;

RSPD3303C_obj  = USB0::0x0483::0x7540::NPD3ECAD2R0396::INSTR

RSPD3303C_obj  = 49138040

RSPD3303C_SET_CURRENT_source (ViSession vi,ViInt32 CH, ViReal64 value);

Hey Slten,

Hope you're well - I appreciate this has been unanswered for a long time so I thought I'd chime in.

It looks like the RSPD3303C is a DC Power Supply so I'd guess that the errors are very code specific. 

Did you ever make progress on this?

Cheers,

Nick
