SUMMARY
 * Use a VBA Procedure to Determine the Current Page of a Tab Control

REFERENCES



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.

Use a VBA Procedure to Determine the Current Page of a Tab Control
CAUTION: If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database.

 Start Microsoft Access. On the Help menu, point to Sample Databases, and then click Northwind Sample Database. Open the Employees form in Design view. On the View menu, click Properties. To select the tab control, in the Form list, select TabCtl0, and then click the Event tab. Click to put the insertion point in the OnChange box, click the Build button (...), click Code Builder, and then click OK.  Copy the following code into the event procedure: Private Sub TabCtl0_Change Select Case Me!TabCtl0.Value ' Returns Page Index. Case 0 ' Page Index for Page 1. MsgBox &quot;You have selected Company Info&quot; Case 1 ' Page Index for Page 2. MsgBox &quot;You have selected Personal Info&quot; End Select End Sub </li> On the File menu, click Close and Return to Microsoft Access.</li> On the View menu, click Form View.</li> On the Personal Info tab, note that the following message appears:

You have selected Personal Info.

</li> On the Company Info tab, note that the following message appears:

You have selected Company Info.
