Indeed, ViEmu exposes a VS service. This provides the following methods: EnterInsertMode(), EnterNormalMode() and GetViMode(). All the details are here:

On the other hand, there is no way to tell if it is active. What do you mean by "active" exactly? Whether it is enabled on Tools|Options|ViEmu or by Ctrl-Shift-Alt-V? I'd have to add a method to the service to allow this.

Hello,

The service proffered by ViEmu is not different from other standard VS services like IVSUIShell, IVsStatusBar, etc... so the same techniques apply.

You need to use QueryService() to access it, and you need to declare the COM interface separately. Here is some code from an example I have in C#, which uses CodeRush to get the service:

------------
[Guid("C93926D3-533A-47BD-A085-DDA86F19D8EC"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IViEmuService2
{
    void EnterInsertMode();
    void EnterNormalMode();
    int  GetViMode();
}

// ...

            if (!tried)
            {
                tried = true;

                IOleServiceProvider isp = CodeRush.ApplicationObject as IOleServiceProvider;

                IntPtr ppObj;
                System.Guid guid_service = new System.Guid("D61C5542-1D52-4731-A789-9A9E5798F052");
                System.Guid guid_iviemu = new System.Guid("C93926D3-533A-47BD-A085-DDA86F19D8EC");
             
                if (isp.QueryService(
                    ref guid_service,
                    ref guid_iviemu,
                    out ppObj
                    ) == DevExpress.CodeRush.Win32.HRESULT.S_OK)
                {
                    viemu_service = Marshal.GetObjectForIUnknown(ppObj) as IViEmuService2;
                }
            }
------------

In non-CodeRush scenarios, you have to get to the service differently. In a package, you are given an IServiceProvider in the SetSite() call. If you are using some 3rd party framework, you probably have a QueryService() you can call internally.

If you are doing an add-in, here is sample code from Microsoft to get a service:

And here is some sample code to do the same from Carlos Quintero, in VB:

Here is some more sample code and an article that seem relevant:

Great to hear that. Let me know if anything else is necessary.
