How are you wanting to use LabVIEW with Virtual Dub? You can programticly launch Virtual dub from LabVIEW with the system exec function.vi . You can find it on the functions >> communications palette.
LabVIEW can interface with external code by calling dlls and by ActiveX calls. It can make some memory calls but this method is less than desirable in LabVIEW. I do not have vitural dub installed on this computer. Does it expose an activeX interface or a dll with a header?
You can learn more about calling dlls in the shipping docs for LabVIEW. Open LabVIEW >> help >> search the LabVIEW bookshelf >> Using External Code in LabVIEW.
The best place to learn about activeX is on the web and in the LabVIEW user manual. Goto : http://search.ni.com/?col=alldocs&layout=TechResources&ql=a and search for activex labview . The user manual can be found by opening LabVIEW >> help >> search the LabVIEW bookshelf >> LabVIEW User Manual.
