Does LabVIEW need an entry point in a DLL

[prone]

We are trying to communicate with a time-to-digital converter card via a DLL provided by the manufacturer. However, this DLL does not seem to have a defined entry point as when we have used Visual Basic 6, VB it errors and tells us there is no entry point.

We can write a wrapper DLL in C but in terms of overheads it would be preferable to go to the original DLL direct.

I know labVIEW can easily load DLLs but can it load a DLL without an entry point? We have a header file which defines the functions.

I hope you can help.

Hi,

The DLL will require an entry point in order for LabVIEW to communicate with it much the same as other languages, otherwise the DLL is a resource and not something useable. The only real way to get this working is to a) wrapper it in C as you noted or b) write the DLL from scratch with an entry point.

All the best,

Rob,
     Thanks, looks like I'll have to make a wrapper.
