C++

public bool CanRun( 
   string commandName, 
   object value 
)

Public Function CanRun( 
   ByVal commandName As String, 
   ByVal value As Object 
) As Boolean

public:  
   bool CanRun( 
      String^ commandName, 
      Object^ value 
   )

Parameters

commandName

Command name

value

Optional value to pass to the callback

Return Value

true if the command can run with the specified value; otherwise, false.

Remarks

This method checks whether the command exists and if so, whether it has a CanRunHandler callback value that is not null. If so, it will invoke the callback with value and return the result.

If the command does not exist or it does not have a handler, then this method returns false - the command cannot run.
