public interface IVsExpansionManager

The IVsExpansionManager type exposes the following members.

Methods

	Name	Description
	EnumerateExpansions	Retrieves a list of code snippets for the specified coding language.
	GetExpansionByShortcut	Retrieves the title and path to a snippet given its shortcut name.
	GetSnippetShortCutKeybindingState	Infrastructure. Determines if a key has been bound to the "Invoke Snippet From Shortcut" command.
	GetTokenPath	Returns the path to the specified location.
	InvokeInsertionUI	Shows an IntelliSense list of code snippets that can be inserted into the source through the provided IVsExpansionClient object.

Remarks

The expansion manager is a helper interface that provides access to information about code snippets. This interface can also present a list of snippets to be inserted at a particular place in a document.

Notes to Implementers

This interface is implemented by Visual Studio.

Notes to Callers

This interface is obtained by calling the GetExpansionManager method in the IVsTextManager2 interface.

Examples

This example shows how to retrieve the IVsExpansionManager interface given a service provider.

using System;
using System.Runtime.InteropServices;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.TextManager.Interop;
using IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop.IServiceProvider;

namespace MyPackage
{
    public class MyClass
    {
        public object GetService(IOleServiceProvider serviceProvider,
                                 Guid serviceGuid,
                                 Guid interfaceGuid)
        {
            IntPtr pUnknown = IntPtr.Zero;
            object unknown = null;
            int hr = serviceProvider.QueryService(ref serviceGuid,
                                    ref interfaceGuid,
                                    out pUnknown);
            if (ErrorHandler.Succeeded(hr))
            {
                unknown = Marshal.GetObjectForIUnknown(pUnknown);
            }
            return unknown;
        }


        private IVsExpansionManager GetExpansionManager(IOleServiceProvider serviceProvider)
        {
            IVsExpansionManager expansionManager = null;
            IVsTextManager textManager;
            textmanager = (IVsTextManager)this.GetService(serviceProvider,
                                                          typeof(SVsTextManager).GUID,
                                                          typeof(IVsTextManager).GUID);
            if (textManager != null)
            {
                IVsTextManager2 textManager2 = (IVsTextManager2)textManager;
                if (textManager2 != null)
                {
                    textManager2.GetExpansionManager(out expansionManager);
                }
            }
        }
        return expansionManager;
    }
}
