//  Member:     CConnectionFolder::QueryStatus

//  Purpose:    [IOleCommandTarget] Queries the object for the status of one 
//              or more commands generated by user interface events.
//
//              This interface is required but is currently unimplemented
//
//  Arguments:  
//      pguidCmdGroup [in]      // Pointer to command group
//      cCmds         [in]      // Number of commands in prgCmds array
//      prgCmds       [in,out]  // Array of commands
//      pCmdText      [in,out]  // Pointer to name or status of command
//
//  Returns:

//  Member:     CConnectionFolder::Exec
//
//  Purpose:    [IOleCommandTarget] Executes a specified command or displays 
//              help for a command.
//  
//              This method is not currently referenced, but if the shell
//              wanted to enumerate only incoming our outgoing connections,
//              it would use the CFCID_SETENUMTYPE command to force the 
//              issue (that is unimplemented on our side, however)
//
//  Arguments:  
//      pguidCmdGroup [in]      // Pointer to command group
//      nCmdID        [in]      // Identifier of command to execute
//      nCmdexecopt   [in]      // Options for executing the command
//      pvaIn         [in]      // Pointer to input arguments
//      pvaOut        [in,out]  // Pointer to command output
//
//  Returns:
