When a user changes the text in a textbox i wish to update the registry key it represents. If I use event TextChanged event then as you type every character in your update the registry routines are called. If I use Validated Event then if you click on the text box or tab past it and not change the text the registry is refreshed. Is there an event that represents "I have changed this text and I have finished changing it now". (Apart from a button next to the text box "Update Registry" :-)

Hi,
AFAIK, there is no such event in .net.
But there is a work around
Use both two events.
Have a dirty flag.
set the dirty flat to true during the TextChanged event.
In the Validated Event, check the dirty flag and call the update registry
method.

R.Balaji

i think the Modified property of the TextBox control is my solution (like the dirty flag suggested). you have to manually reset it. here is what i am using:
Private Sub txtServer_Valid ated(ByVal sender As System.Object, ByVal e As System.EventArg s) Handles txtServer.Valid ated
If txtServer.Modif ied Then
txtServer.Modif ied = False
ra = New RegistryAccess
ra.PutKey(ra.Re gistryKeys.Data baseServer, txtServer.Text)
ra = Nothing
End If
End Sub

Why don't you monitor the key press event and, for example, on Enter key you
save the value you want?

WINDOWS FORMS
I've a form that has a textbox that allows the user to enter a string.
On the LostFocus event, the textbox formats the string into a preferred
format.
However, if the user presses the "Save" button while the textbox has
the focus, the LostFocus code doesn't run at the right time, so that
the "Save" function is dealing with an incorrectly formatted string and
the whole caboodle goes splat.
