Hi,
Sure you can, first you need to include the name of your callback function when you create your tab ex:
iMainTabCtrl=EasyTab_Create (ipanel, 8, 46, MyCallBackTab, 0); // Check the help on this control
then you write down your Callback as usual, but with the EVENT_TAB_CHANGED. Then you can read wich tab as been called an do whatever you want.
By the way don't forget after creating your CVICALLBACK to declare the prototype.
if you have any other question regarding tabs feel free to ask me. I'm dealing with a lot of them ;-).
I hope that I helped...
