Hi
Something that's proving to be a little tricky. Here's the scenario:
I have a table of Clients, each of which can have zero or more Contacts. Clicking the Contacts button on the Client form opens a pop-up form that displays the Client's Contacts.
Each Client can have a default Contact, indicated by a DefaultContact checkbox on the Contact form. If the user checks this checkbox, I want to run a piece of code that checks whether any of this Client's Contacts are already set as default and, if so, warns the user before proceeding. If the user goes ahead, 'default' status is assigned to the current Contact & removed from the other.
It seems to me that the obvious place to do this is on the Contact form's BeforeUpdate event, when the record is being saved. However, it's only necessary to do this when the DefaultContact checkbox has been clicked. But there's no 'Dirty' flag for checkboxes & the only way I can think of is to set a global (within the scope of the form) variable and get the BeforeUpdate code to check it before running my 'Default Contact' code above.
It seems clumsy and I'm wondering if any of you more experienced Access programmers know of a better way to do this.
Thanks
