I have what is basically an Email address book that will send email addresses to another form. The way it works now, the 'Send Email' command button's click checks to see if alltrim(emailtextbox) is equal to alltrim(newtextbox). What I want it to do is check to see if alltrim(emailtextbox) is contained somewhere within the new textbox. The reason I want it to work this way is that the user can send several email addresses to newtextbox for one email to be sent to several people. Since you can't see all of the email addresses you have entered, people might accidentally include the same email address twice and send to copies of the email to the same person. So how do I get FoxPro to tell me if the email address I'm trying to add is somewhere in the list of addresses I've already added?
