We are working with Tektronix to provide LabVIEW support for this and other oscilloscope drivers. You will see these drivers on Tektronix's and NI's websites in the near future.
However, until they are released, your best option is to use the LabVIEW "Tools >> Instrumentation >> Import CVI Instrument Driver..." feature to convert the CVI driver into LabVIEW.
This
tutorial will help you. You can skip the first step since you already have a DLL.
