using a driver with labview

[mjtompki]

I want to create a GUI using labview to control a data acquisition card using a driver that was not created in labview. Could someone point me in the direction of some documentation that would give me some info on doing this.

Thanks

If you're using a non NI data acquisition card and the manufacturer doesn't have a LabVIEW driver, then you'll probably be using either a DLL or ActiveX interface that they provide. For interfacing to third praty DLLs, start with "Using External code in LabVIEW" that is part of the LabVIEW Bookshelf. You will need details from the manufacturer on the function calls. There are some shipping examples on ActiveX. The Invoke Node and Property Node functions on the Communication>ActiveX palette are used to access methods and properties.

If you were to mention the make and model of the board you're using, you might find someone here with knowledge of it that would provide more details.

Thanks for your help. I am using a measurement computing PCI-DAS 1001 but the driver was written independently of the company. I have all the documentation from the driver so i dont think that creating an DLL to bridge the gap between labview and the driver will be that difficult.
