textbox text changed event

[Drstein99]

I'm using vb.net and I want to know if the textbox changed event is being executed from the user changing it or by another function. Because I have functions in the program to clear the text box, and it may be executing from that other function. I cant figure out these parameter/arguments the .net help is too vauge - please help, thanks

 

 

Private Sub tbs_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tbSText.TextChanged

Yes, TextChanged event will fire if you change the text from code.

Ok thanks for the info. I know that. I guess I didnt phrase my question correctly, please allow me to try again:

 

HOW can I find out from the parameters if the event was activated by the user OR another function?

Do a:

 

messagebox.show(sender.GetType.ToString)

 

may be you can do somthing like:

 

If sender.GetType.ToString = "stuff" Then
 'this
Else
 'that
End If

It returns:

 

systems.windows.forms.textbox

 

Every time whether I'm updating the window through keypress or not.

You could try using the KeyPress event. You may have to handle special cases (for example, if I press the Enter key in a non-multiline textbox, KeyPress will still fire even if the text itself doesn't change) but it appears to be the only way to do it.

Thats what I ended up doing. Thanks.
