.well i want to call another program, e.g Theres a 3 buttons "red, blue, green" : when i click red, its going to call a program to add the numbers. when i click green, its going to call another program to subtract. and when i click blue, its going to call another program to divide. So there are 4 programs to connect. The RED, BLuE, Green and the Main program. ^^
