is it possible to dynamically change whether a button is visible or not during run-time.

i need something similar to this:
http://www.coniserver.net/ubbthreads/showflat.php/Cat/0/Number/770585/an/0/page/0#Post770585

I have a panel that displays buttons (names) of previously visited locations. the player can bring up the menu and select the location and teleport there, but only places that he has already visited. I don't want the player to see places that he has NOT already visited.

i am having problems programming this. The manual says i can use the dot modifier, but not to access the indivisual buttons.

Can someone help me? Any suggestions would be appreciated or perhaps maybe there is a different method?

You should take a look at "pan_setbmap"
Here: http://manual.conitec.net/pan_setbmap.htm

The idea:
Set the buttons which should be invisible to a completly black bitmap.
This way they are "hidden", of course you might need to add an if statement to the function of the button to check if it is visible (=> proceed) or not.

thank you, i do believe this will work well.

well, i thought it would, but it seems that's an lite-c function. I'm still using c-script. Is there, perhaps, similar function in c-script. I really am not ready to convert all those pages of code just yet.

i think, maybe i should create several panels to cover each button, and as the player goes to each location have the script turn off that particular panel.

i will see how that works out.

No that one is definatly c-script.
