I wouldn't put the IDs in an array, but pointers to the buttons instead. Otherwise you'll have to call FrmGetObjectPtr for all the buttons every time you want to do an operation on all the buttons. Not a good idea as you should minimize the code that's being executed inside a for loop...

I am using Codewarrior 9.2; how can I change their IDs (or > just put them in a two-dimention array according to their positions)? I think you answered your own question. Make an array (1D or 2D whichever is more appropriate for what you need to do with them) and just copy all the values into the array. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
