Highlight Text If null

J

I have the following code in the save command button on my form. A pop
up message tells me i forgot to put address info and will take me to
address field.

If IsNull(Me.Address) Then
MsgBox "Address Required.", , "Missing Information"
Me.Address.SetFocus
Exit Sub
End If

what i want to do is highlight the text box red once user clicks
on address and puts the address the color will change from red back to
the default color of the text box which is white


Any Ideas

Jeremy, if it is important to you to check the address has a value, the code
needs to go into the BeforeUpdate event of the *form*, not merely the Click
event of your button. Your button's click can then just force the record
save like this:
RunCommand acCmdSaveRecord
and that triggers the checks in Form_BeforeUpdate.

To answer your question, add the line:
Me.Address.BackColor = vbRed

Then in the AfterUpdate event of the control, you can test it with IsNull(),
and set the control's BackColor back to vbWhite.
