VS2017开发activex

activex开发有多种方式，可以是用MFC C++， C#，

以C# windows窗体控件库（.NET Framework）

新建IObjectSafety.cs文件

using System;
using System.Runtime.InteropServices;
namespace ActiveXDemo
{

[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
public interface IObjectSafety
{
[PreserveSig]
int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

[PreserveSig()]
int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
}
}

修改UserControl.cs文件

using System;
using System.Runtime.InteropServices;
namespace ActiveXDemo
{

[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
public interface IObjectSafety
{
[PreserveSig]
int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

[PreserveSig()]
int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
}
}

然后，修改Guid 改为自己新建的，点击工具->创建Guid
