labview 8.6 DLL to Vb.net 2008. Passing a 1D Array and returning an Array

[BrianNeuroscience]

I need to achieve the exact same thing.  Please reply if you have found a successful solution and help out progress in neuroscience =).  I am new to creating dll's with labview and do not have simple integers working yet, I am getting a pinvoke restriction error.  Will need to also send in arrays though like the original poster.

Hi Brian,

Did the exmaple seen on the previous not solve your question?

I have a very simple dll working now, but I am having trouble specifically with passing by refs because I get a protected memory error.  Trying to troubleshoot that now.

Haven't tried starting to use arrays yet, but the example seems somewhat complicated to follow.  The documentation is pretty sparse =(.

Hi Brian,

I think the following articles would help you while building your DLL:

How Can I pass a Multidimensional Array from VB to a LabVIEW built DLL? 

How Do I pass Arrays to an Instrument Driver DLL in Visual Basic? 

What are the Differences Between Array Data Pointer, Array Handle, and Array Handle Pointer?

Why Do I Get Error 988 when I try to Call a DLL in LabVIEW?

If you have more questions please feel free to repost. 

Cheers,

I also want to make a dll that accept 1d Array by using labview 8.6 and vb.net. I seached it on google and reading upper guides in the thread as well, still no ideas on it. Can anyone share a exactly vb.net sample for it?
