) As Boolean

'Usage

Dim instance As DocumentViewerCommands
Dim commandName As String
Dim value As Object
Dim value As Boolean
 
value = instance.CanRun(commandName, value)

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 if the command exists and if it has a CanRunHandler callback value that is not null, if so, it will invoke the callback with value and returns the result.

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