I have a main form that shows another options dialog. Once the options form has been changed, I want properties on the main form to be changed as a result. However, how could I detect if the variables have been changed? BTW, I am sharing the vars in a module. I considered making it detect the vars once the user moves his mouse over the main form, but I want to know if there is a better way. Would a timer be better or is there an even better way? Thanks!
