Syntax

'Declaration

JScript does not support explicit interface implementations.

Parameters

guidGroup
Type: Guid%

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

nCmdId
Type: UInt32

System.UInt32 nCmdId. The ID code of the command. This implementation maps nCmdId to CommandID.ID.

oleCmd
Type: array<Microsoft.VisualStudio.OLE.Interop.OLECMD[]

Microsoft.OLE.Interop._tagOLECMD[] oleCmd. A command structure that contains data about the status of the command.

oleText
Type: IntPtr

System.IntPtr oleText. A pointer to a text BSTR. If the command is a verb the name of the verb will be filled in here.

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.QueryStatus(Guid%, UInt32, array<OLECMD[], 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 QueryStatus uses FindCommand if a command exists, and then sets oleCmd.cmdf to the status code returned by the command’s OleStatus property.

.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.
