Labview Data types and calling 'C' Dlls

[Martin Riddle]

I see this question has been posted before, and I have found some answers.
But is there a resource that I can reference for more answers?
Questions like what is the data type for a Occurrence type? (this appears to
be a ULONG32).
'Using External Code in Labview' is helpful but does not have all the
answers.
Is there anything that can make our lives easier? instead of flattening the
data type and guessing?


TIA
&
Happy Holidays!!!!!!!

Application note 154 used to have all of these answers.

My saved link fails indicating that NI is updating this document.

The only idea I can offer is contact NI directly and see if you can get them to give you a copy of what they have.

Sorry I did not down load this when I had the chance.

Martin,
Here is the updated "Using External Code In LabVIEW" document, that I hope you'll find has more answers.

Thanks Ben, that was helpfull. Even though the document 'is under review'
the site returned revelant results. This link I found quite helpfull

It gives a little insite on how to decipher Labview data types, bacisly the
same a flat
tening. I can reconize the Occurence type by this method. But, a
Generate occurrence type is not the same as a Occurence RefNum control. Even
though the type descriptors are the same! (odd, I just discovered this)
Hopefully Appnote 154 gets updated.

Wait I googled for it and here is an April-03 rev of it!
