WinCVS is an interface to a CVS repository. While it allows you to work with CVS controlled files, it is a stand-alone application similar to Tortoise CVS. LabVIEW 8.x works with source control providers that support the Microsoft source control interface. In practice, this means that source control providers that integrate with Visual Studio typically will work with LabVIEW (I say typically since some providers tailor their interfaces to Visual Studio). So for CVS, there are some applications that allow IDEs (like Visual Studio) to work with CVS repositories. Look for key works like "plug-in for Visual Studio" or "SCC integration". From WinCVS's web page there is a section called "Projects related to WinCVS". Take a look at these products and see if they will work for you. They won't be WinCVS, but may allow you to work with your CVS controlled files from within LabVIEW. As the previous post noted, PushOK is another developer that has a plug-in for CVS.
