在.NET环境中编译VB6代码

Question

Is one able to compile VB 6 code in Visual Studio.NET ? In other words, is it backwards compatible with older VB code?

Since I know there is a difference between managed code (.NET) and unmanaged code, I am wondering if Visual Studio.NET is able to compile unmanaged code as well?

Kind regards, Kris

虽然您无法在.net Visual Studios中编译vb6，但您可以使用互操作库来允许vb.6使用托管代码http://msdn.microsoft.com/en-us/library/kew41ycz%28VS.71%29。 ASPX

不，你不能在任何VS.NET版本中编译VB6代码。

Answer 3

You can open a VB6 .vbp project file in Visual Studio. This automatically invokes the project converter, it will try to translate your VB6 code into VB.NET. The translator does a fairly decent job of it but the VB.NET language has changed pretty drastically. It depends on how 'clean' your VB6 code was.

After the conversion is completed, you'll have to walk through the list of warnings and errors you'll get. Getting none at all is rare. There might be hundreds or thousands. If you're in that boat, it starts making sense to rewrite the code.

Anyhoo, just try and see what hits the fan. You'll have a good idea what you're in for in about ten minutes. Don't forget to copy the project before you start the conversion.

No it is not compatible. I think there is an upgrade wizard, but you will end up fixing some stuff manually.
