JScript does not support explicit interface implementations.

Parameters

guidGroup
Type: Guid%

The menu group. This implementation maps the group to CommandID.Guid.

nCmdId
Type: UInt32

The ID code of the command. This implementation maps nCmdId to CommandID.ID.

nCmdExcept
Type: UInt32

The number of command options. This implementation ignores this parameter.

pIn
Type: IntPtr

The actual command options. This implementation ignores this parameter.

vOut
Type: IntPtr

Output data for the command. This implementation ignores this parameter.

Return Value

Type: Int32
An HRESULT code indicating the success or failure of the call. The following HRESULTs may be returned:

Value	Description
S_OK	The command was successfully invoked.
OLECMDERR_E_UNKNOWNGROUP	The group GUID did not match the commandID’s Guid property for any command or verb.
OLECMDERR_E_NOTSUPPORTED	The group was found, but there is no command or verb with an ID that matches. This is also returned if the OleStatus property of a command that was found returns zero.

Implements

IOleCommandTarget.Exec(Guid%, UInt32, UInt32, IntPtr, IntPtr)

Remarks

This method is defined as a private interface implementation for IOleCommandTarget. To make use of it, a tool or document window generally implements IOleCommandTarget itself, and then forwards calls to the implementation contained in MenuCommandService. This implementation of Exec uses FindCommand to determine if a command exists, and invokes the command if it is disabled.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
