  Set a variable inside your code that reflects when you want the buttons to work. In the button event for the external button test if that variable is on or off.

  I understand it. I can not find a team that can disable the external buttons on mio r4 upon the occurrence of certain events.
  
  For example
  button_event [mio_1, key_volup] {push: {send_string dvReciv, 'volup}
  button_event [mio_1, key_voldw] {push: {send_string dvReciv, 'voldw}
  Etc.
  
  If (event1= 1) {*disable key_volup and voldw*} --- what command for disable?
  
  in the project I made the substitution device. it works, but I think this is the wrong decision.
  
  Example
  
  Define_variables
  DEV void_dev
  
  Define_event
  
  Channel_event {mio_1,button} {
  on: dvReciv = void_dev
  Off: dvReciv = 5001:1:1}
  
  button_event [mio_1, key_volup] {push: {send_string dvReciv, 'volup}
  button_event [mio_1, key_voldw] {push: {send_string dvReciv, 'voldw}
  
  Etc))))

  Try something like this:

  BUTTON_EVENT[mio_1,0]//0 catches all button events for the mio_1 dev/port
  
       {
       PUSH:
  	  {
  	  STACK_VAR INTEGER nBtn;
  	  
  	  nBtn = BUTTON.INPUT.CHANNEL;
  	  
  	  if(!nDisable)//prevents the following buttons from firing if set
  	       {
  	       SWITCH(nBtn)//these buttons will work if nDisable is not set as long as a case matches nBtn
  		    {
  		    CASE key_volup:{send_string dvReciv, 'volup';}
  		    CASE key_voldw:{send_string dvReciv, 'voldw';}
  		    CASE key_volxx:{send_string dvReciv, 'volxx';}
  		    CASE key_volyy:{send_string dvReciv, 'volyy';}
  		    }
  	       }
  	  SWITCH(nBtn)//these buttons will work regardless of the disable flag as long as a case matches nBtn
  	       {
  	       CASE key_disable:{nDisable = !nDisable;}
  	       CASE key_pwr_on: {send_string dvReciv, 'pwr_on';} 
  	       CASE key_pwr_off:{send_string dvReciv, 'wr_off';}
  	       }
  	  }
       }
  

  instead of changing your dev to a null which will likely just piss off the master when it tries to send a string to it unless your null is a virtual that is.
  
  Just set a var and use as a flag to determine if button pushes should be processed or not which is what AMXJeff was talking about.
