HOW TO: Use a VBA Procedure to Determine the Current Page of a Tab Control in Microsoft Access 2002 (324583)

SUMMARY

You can run Visual Basic for Applications (VBA) code based on the tabs that are selected in a tab control. To make sure that a particular block of code runs when you click a particular tab, use a SELECT CASE statement with the Change event of the tab control itself, instead of using the Click event of the particular page.

In a tab control, a tab contains a page, but it is not actually part of the page itself. Therefore, the Click event of a page occurs when you click in the body of the page, but the Click event does not occur when you click the corresponding tab of the page. However, the Change event occurs every time you click a different tab. You can then use the SELECT CASE statement to direct the flow of your code so that it depends on the index of the current page. The Value property of a tab control returns the index of the current page.
