IEnumRunningDocuments Interface


Represents a list of Running Document Table (RDT) cookies that in turn each represent an open document.

Namespace:   Microsoft.VisualStudio.Shell.Interop
Assembly:  Microsoft.VisualStudio.Shell.Interop (in Microsoft.VisualStudio.Shell.Interop.dll)

public interface IEnumRunningDocuments


Creates a copy of this IEnumRunningDocuments object.

System_CAPS_pubmethodNext(UInt32, UInt32[], UInt32)

Returns a specified number of document cookies from the enumeration sequence.


Resets the enumeration sequence to the beginning


Skip over the specified number of document cookies in the enumeration sequence.

The RDT represents each open document in Visual Studio by a unique value known as a cookie. The IEnumRunningDocuments interface enumerates all cookies representing all open documents.

A cookie as used by the RDT is represented as a VSCOOKIE type. In C++, this is defined as a DWORD_PTR (or DWORD *) while in managed code such as C#, the VSCOOKIE is treated simply as an unsigned integer (uint). However, a cookie is a value that only the RDT knows how to use so always consider it as just an unsigned number to be passed around.

Notes to Implementers:

This interface is implemented by the environment for accessing a list of open documents as maintained by the RDT.

Notes to Callers:

Obtain this interface from the GetRunningDocumentsEnum method in the IVsRunningDocumentTable interface.
