Syntax
'宣告
Private Function Exec ( _
ByRef guidGroup As Guid, _
nCmdId As UInteger, _
nCmdExcept As UInteger, _
pIn As IntPtr, _
vOut As IntPtr _
) As Integer Implements IOleCommandTarget.Exec
int IOleCommandTarget.Exec(
ref Guid guidGroup,
uint nCmdId,
uint nCmdExcept,
IntPtr pIn,
IntPtr vOut
)
Parameters
- guidGroup
Type: System.Guid%
The menu group. This implementation maps the group to CommandID.Guid.
- nCmdId
Type: System.UInt32
The ID code of the command. This implementation maps nCmdId to CommandID.ID.
- nCmdExcept
Type: System.UInt32
The number of command options. This implementation ignores this parameter.
- pIn
Type: System.IntPtr
The actual command options. This implementation ignores this parameter.
- vOut
Type: System.IntPtr
Output data for the command. This implementation ignores this parameter.
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.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.
