Data Validation for all ActiveX Text Boxes

I want to add simple data validation (numbers only) to many (10+) ActiveX text boxes. I know I can call a Sub for each TextBox_Change() event, but I need to know if I can create a function that activates when any text box is changed without asking each box to call the function. Does anyone know how to do this? Thanks in advance.
