Method Details

CommandFilter() protected method

Initializes a new instance of the CommandFilter class.

protected CommandFilter ( ) : System
return	System

Connect() protected abstract method

Enables the command filter by connecting it to a chain of command targets.

Do not call this method directly. This method is called as necessary when Enabled is set to .

protected abstract Connect ( ) : Microsoft.VisualStudio.OLE.Interop.IOleCommandTarget
return	Microsoft.VisualStudio.OLE.Interop.IOleCommandTarget

Disconnect() protected abstract method

Disables the command filter by disconnecting it from a chain of command targets.

Do not call this method directly. This method is called as necessary when Enabled is set to .

protected abstract Disconnect ( ) : void
return	void

Dispose() public method

public Dispose ( ) : void
return	void

Dispose() protected method

Releases the unmanaged resources used by this instance.

When disposing is , the default implementation sets Enabled to .

protected Dispose ( bool disposing ) : void
disposing	bool	if this method is being called from ; otherwise, if this method is being called from a finalizer.
return	void

HandlePostExec() protected method

This method supports specialized handling in response to commands that are successfully handled by another command target.

This method is only called if HandlePreExec for the current instance returned and the next command target in the chain returned a value indicating the command execution succeeded.

The default implementation is empty.

protected HandlePostExec ( System.Guid &commandGroup, uint commandId, Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT executionOptions, IntPtr pvaIn, IntPtr pvaOut ) : void
commandGroup	System.Guid	The command group.
commandId	uint	The command ID.
executionOptions	Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT	The OLE command execution options.
pvaIn	System.IntPtr	An optional pointer to the command argument(s). The semantics of this parameter are specific to a particular command.
pvaOut	System.IntPtr	An optional pointer to the command result(s). The semantics of this parameter are specific to a particular command.
return	void

HandlePreExec() protected method

This method supports the implementation for commands which are directly implemented by this command filter.

The default implementation returns for all commands.

protected HandlePreExec ( System.Guid &commandGroup, uint commandId, Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT executionOptions, IntPtr pvaIn, IntPtr pvaOut ) : bool
commandGroup	System.Guid	The command group.
commandId	uint	The command ID.
executionOptions	Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT	The OLE command execution options.
pvaIn	System.IntPtr	An optional pointer to the command argument(s). The semantics of this parameter are specific to a particular command.
pvaOut	System.IntPtr	An optional pointer to the command result(s). The semantics of this parameter are specific to a particular command.
return	bool

QueryCommandStatus() protected method

Gets the current status of a particular command.

The base implementation returns 0 for all commands, indicating the command is not supported by this command filter.

protected QueryCommandStatus ( System.Guid &commandGroup, uint commandId ) : Microsoft.VisualStudio.OLE.Interop.OLECMDF
commandGroup	System.Guid	The command group.
commandId	uint	The command ID.
return	Microsoft.VisualStudio.OLE.Interop.OLECMDF

QueryParameterList() protected method

protected QueryParameterList ( System.Guid &commandGroup, uint commandId, Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT executionOptions, IntPtr pvaIn, IntPtr pvaOut ) : int
commandGroup	System.Guid
commandId	uint
executionOptions	Microsoft.VisualStudio.OLE.Interop.OLECMDEXECOPT
pvaIn	System.IntPtr
pvaOut	System.IntPtr
return	int

ThrowIfDisposed() protected method

Throw an ObjectDisposedException if the current instance has been disposed.

If the current instance has been disposed.

protected ThrowIfDisposed ( ) : void
return	void
