ObjectFrame.Tag Property (Access)

Stores extra information about a form, report, section, or control needed by a Microsoft Access application. Read/write String.

expression .Tag

expression A variable that represents an ObjectFrame object.

You can enter a string expression up to 2048 characters long. The default setting is a zero-length string (" ").

Unlike other properties, the Tag property setting doesn't affect any of an object's attributes.

You can use this property to assign an identification string to an object without affecting any of its other property settings or causing other side effects. The Tag property is useful when you need to check the identity of a form, report, section, or control that is passed as a variable to a procedure.

The following example uses the Tag property to display custom messages about controls on a form. When a control has the focus, descriptive text is displayed in a label control called lblMessage. You specify the text for the message by setting the Tag property for each control to a short text string. When a control receives the focus, its Tag property is assigned to the label control's Caption property. This example displays the descriptive text for a text box named txtDescription and a command button named cmdButton on a form.

Sub Form_Load() 
 Dim frmMessageForm As Form 
 
 Set frmMessageForm = Forms!Form1 
 
 frmMessageForm!lblMessage.Caption = "" ' Clear text. 
 frmMessageForm!txtDescription.Tag = "Help text for the text box." 
 frmMessageForm!cmdButton.Tag = "Help text for the command button." 
End Sub 
 
Sub txtDescription_GotFocus() 
 ' Tag property setting as caption. 
 Me!lblMessage.Caption = Me!txtDescription.Tag 
End Sub 
 
Sub txtDescription_LostFocus() 
 Me!lblMessage.Caption = "" 
End Sub 
 
Sub cmdButton_GotFocus() 
 ' Tag property setting as caption. 
 Me!lblMessage.Caption = Me!cmdButton.Tag 
End Sub 
 
Sub cmdButton_LostFocus() 
 Me.lblMessage.Caption = " " 
End Sub
