Say i have the following setup



What i am trying to do is, when the user clicks on the 'calculate age ' button it must calculate the age and display the result based upon the selection in the combobox i.e if 'Days' are selected then it must display in days, if weeks are selected then it must display in weeks..etc

Similarly when the user clicks on the 'convert to date' button , it must subtract the given days(or weeks or months or years) from Todays date and set it to the maskedbox
