New user trying to create a dll using vc++ to be used with VB

[perk_bud]

I need guidance  about how to go about creating a DLL using VC for NI USB 6009 device .I dont have either Lab view nor measurement studio software.I just recently got a Multifunctional DAQ NI USB 6009 which come with the basic DAQmx software.I'm trying a create a DLL to comunicate with the device and read and send signals through the device to the end hardware.The Main software is written in VB. So the VB software will comunicate through the DLL..An example code would be very helpful.

Hi perk_bud,

Rather than using a separate DLL, I’d suggest just using Visual Basic to perform the DAQmx function calls.  There are a lot of examples located in the DAQmx folder.

C:\Program Files\National Instruments\NI-DAQ\Examples

This folder contains Visual Basic examples, as well as C examples in case you do decide to use a DLL.

Also, the DAQmx help documentation contains some good information.  Check out the “NI-DAQmx C API Visual Basic 6.0 Help”.  This is located in the Start menu under Programs >> National Instruments >> NI-DAQ.

Hope this helps!
