Unable to get window handle, Windowless ActiveX controls are not supported?
提问by jasonh
I upgraded my development machine to Windows 7 and my project to .NET 3.5. When I try to run the project, I now get this error:
我将我的开发机器升级到 Windows 7，将我的项目升级到 .NET 3.5。当我尝试运行该项目时，我现在收到此错误：
Unable to get the window handle for the 'AxVt' control. Windowless ActiveX controls are not supported.
The project is using the Dart Emulation for ActiveX Vt control, which emulates a terminal control. I double-checked and the program launches fine under Windows XP SP2 with .NET 3.5, so it's not the Framework causing the issue. Setting compatibility mode to Windows XP SP2 doesn't help either. This exception occurs when the designer code calls EndInit on the control.
该项目使用 Dart Emulation for ActiveX Vt 控件，它模拟终端控件。我仔细检查过，程序在带有 .NET 3.5 的 Windows XP SP2 下正常启动，所以不是框架导致了问题。将兼容模式设置为 Windows XP SP2 也无济于事。当设计器代码在控件上调用 EndInit 时会发生此异常。
Is there any way to work around this or does it just mean I have to remove Windows 7 from my machine and go back to Windows XP?
有什么办法可以解决这个问题，还是只是意味着我必须从我的机器上删除 Windows 7 并返回到 Windows XP？

Try switching DEP off just to see if is that issue, I had it before, check here: http://blogs.msdn.com/ed_maurer/archive/2007/12/14/nxcompat-and-the-c-compiler.aspxto find out how.
尝试关闭 DEP 以查看是否是那个问题，我以前遇到过，请在此处查看：http: //blogs.msdn.com/ed_maurer/archive/2007/12/14/nxcompat-and-the-c-compiler。 aspx以了解如何操作。

It is quite likely that the third party control you're using doesn't (yet) work with Windows 7, since it's still in beta. Have you checked with the maker?
您使用的第三方控件很可能（还）不适用于 Windows 7，因为它仍处于测试阶段。你和厂家确认了吗？
Most software implemented on top of both COM and the Windows APIs is likely to end up with difficulties when switching between versions of Windows, particularly versions that didn't exist when the software was written. Hopefully, with a bit of time, the company making the product will have a hotfix or update for you.
大多数在 COM 和 Windows API 之上实现的软件在 Windows 版本之间切换时可能会遇到困难，尤其是在编写软件时不存在的版本。希望一段时间后，生产该产品的公司将为您提供修补程序或更新。
