Hi,
I don't know any automated way to create inclemental builds in CVI, I don't think the ActiveX interface for CVI will allow you to change the Target Settings. You would have to do it manualy before any export. What CVI does have is support for third party sounce code control software that can keep track of versions and history.
About the version information, there is a good example that can give you the version infomrmation of any exe; including the ones created with CVI. you can find it here:

Hope that helps.
