接触一些旧的 Protoview VB6 控件
我从一位客户那里继承了一个项目，他相信自己拥有所有源代码，但不幸的是，这个特定的 VB6 应用程序使用了一堆原始程序员不会放弃的自定义控件（实际上他可能自己购买了许可证，所以他不交出它们可能是对的，另一方面，由于他已被项目切断，可能会涉及到一些怨恨 - 我不知道，这并不重要。）
无论如何，该项目使用以下控件：
- PVOutlookBar.ocx
- PVList.ocx
- PVCombo.ocx
- PVXplore8.ocx
- PVDateEdit.ocx
- PVTime.ocx
- PVDt80.ocx
据我所知，它们来自一家名为 Protoview 的公司，该公司已被 Infragistics 收购......并且这些控件都不是尽管可以全价购买，但不再受支持。
我的客户非常不愿意花费超过 1000 美元来获得这些控件，特别是因为
1) 它们不再受到供应商的支持
2) 我们不能保证如果购买了这些控件它就能工作（即也许有还有很多其他东西也丢失了）。
3) 即使我们买错了东西，也不会退款...
4) 我们只需要让它运行得足够好，就可以将端口启动到更新的语言，vb.net 或 C#（因此可能需要再次购买控制器）。
我的问题是，如果有人拥有这些控件并且不再使用它们来出售它们，这是否合法？我认为，如果您不再使用某个软件，您可以转让许可证（希望找到拥有这些许可证的人，并且愿意以比购买新软件低得多的价格放弃它们） ）。
有人知道购买“旧”软件的任何来源，尤其是诸如此类的控件吗？我找到了 Retrosoftware 网站（不再运行），但他们没有我需要的任何东西。 谢谢。
I have inherited a project from a client, who believes he has all the source code, but unfortunately this particular VB6 application used a bunch of custom controls that the original programmer will not give up (he may in fact have purchased the licenses himself, so he may be right in not turning them over, on the other hand since he has been cut-off from the project there may be a bit of spite involved - I have no idea and it doesn't really matter.)
Anyway, the project uses the following controls:
- PVOutlookBar.ocx
- PVList.ocx
- PVCombo.ocx
- PVXplore8.ocx
- PVDateEdit.ocx
- PVTime.ocx
- PVDt80.ocx
and as far as I can tell they were from a company called Protoview which was bought up by Infragistics...and none of these controls are supported anymore, though they can be purchased at full price.
My client is very reluctant to spend over $1000 to get his hands on these controls, especially since
1) they are no longer supported at all by the vendor
2) we have no guarantee that if these are purchased that it will work (i.e. maybe there is a lot of other stuff missing too).
3) there are no refunds, even if we bought the wrong stuff...
4) we only need to get it running enough to start the port to a more updated language, either vb.net or C# (and thus would need to possibly buy the controls again).
My question is, is it legal if someone had these controls, and was no longer using them, to sell them? I would assume that the if you were no longer using a piece of software, you could transfer the license (the hope would be to find someone who has them lying around and would be willing to part with them for a lot less than buying the new).
Anyone know any sources for buying "old" software, especially controls such as these? I found Retrosoftware website (no longer operational) but they don't have any of the stuff I need.
Thanks.

我不是律师，但我认为转让许可证的合法性取决于 ProtoView 使用的控件的原始许可条款。有些许可证允许它，有些则明确禁止它。
当然，Infragistics 当前使用的许可协议不允许您转让许可。
I Am Not A Lawyer, but I think the legality of transferring a license depends on the original license terms for the controls used by ProtoView. Some licenses allow it and some explicitly forbid it.
Certainly the license agreement Infragistics is currently using does not allow you to transfer the license.
