OleMenuCommandService.IOleCommandTarget.QueryStatus Method
This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
Sets command status.
Namespace: Microsoft.VisualStudio.Shell
Assembly: Microsoft.VisualStudio.Shell.11.0 (in Microsoft.VisualStudio.Shell.11.0.dll)
Syntax
'宣告
Private Function QueryStatus ( _
ByRef guidGroup As Guid, _
nCmdId As UInteger, _
oleCmd As OLECMD(), _
oleText As IntPtr _
) As Integer Implements IOleCommandTarget.QueryStatus
int IOleCommandTarget.QueryStatus(
ref Guid guidGroup,
uint nCmdId,
OLECMD[] oleCmd,
IntPtr oleText
)
Parameters
- guidGroup
Type: System.Guid%
System.Guid guidGroup. The menu group. This implementation maps the group to CommandID.Guid.
- nCmdId
Type: System.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: System.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: System.Int32
An HRESULT code indicating the success or failure of the call. The following HRESULTs may be returned:
Value |
Description |
|---|---|
The command was successfully invoked. |
|
The group GUID did not match the commandID’s Guid property for any command or verb. |
|
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.
