Using nidaq32.dll in VB.NET

[TrueIndian]

Hello Everyone,

I am trying to read some values from the NI PCI 6023E (Legacy) A/D card. I installed the traditional NI-DaQ and was able to read the values using VB6 program and NIDaq32.bas after doing a bug fix using palBase. But, When I tried to use the simillar code in VB.NET, I was getting an error " An unhandled exception of type 'System.NullReferenceException' occurred in VBNETprogram.exe  Additional information: Object reference not set to an instance of an object."

Will I be able to use the same PCI 6023E Legacy A/D card with the new dll file that comes with NI-Daqmx version?

Thanks in advance for your response.

Thank you for contacting National Instruments.

I checked the Readme for NI-DAQmx 7.5 (ftp://ftp.ni.com/support/daq/pc/ni-daq/daqmx/7.5/readme.html#devSupport), and the 6023E is listed as a supported device in NI-DAQmx, and it works in Visual Basic.NET.
