JScript does not support explicit interface implementations.

Parameters

guidGroup
Type: System.Guid%
Unique identifier of the command group. All the commands that are passed in the prgCmds array must belong to the group that is specified by guidCmdGroup.

nCmdId
Type: System.UInt32
The number of commands in the prgCmds array.

oleCmd
Type: array<Microsoft.VisualStudio.OLE.Interop.OLECMD[]
A caller-allocated array of OLECMD structures that indicate the commands for which the caller requires status information. This method fills the cmdf member of each structure with values taken from the OLECMDF enumeration.

oleText
Type: System.IntPtr
Pointer to an OLECMDTEXTF structure to return a name and/or status information of a single command. Can be nulla null reference (Nothing in Visual Basic) to indicate that the caller does not require this information.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Implements

IOleCommandTarget.QueryStatus(Guid%, UInt32, array<OLECMD[], IntPtr)
