TextChanged is only called when the user modifes a control's text, not
if the program does.
How can I make it be called when the program modifies the text?

Just call the method.

Tomb,
Thanks for the reply.
I can't just call TextBox1.TextCh anged(), since it's an event. I need
to use RaiseEvent to do that, which can only be used on declared
events.
I could call TextBox1_TextCh anged(), the function that the event
invokes. But, what do I pass it as arguments?
Even if I CAN pass the proper arguments, I'd have to make this call in
*every place* that I manually change the text. <sigh>
There has got to be a better way that just invokes the event when the
text is changed, no matter WHO changes it.

Are you sure? The following works fine for me...
Private Sub TextBox1_TextCh anged(ByVal sender As System.Object,
ByVal e As System.EventArg s) Handles TextBox1.TextCh anged
Me.TextBox1.Bac kColor = Color.Red
End Sub
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e
As System.EventArg s) Handles Button1.Click
Me.TextBox1.Tex t = "hello"
End Sub
As soon as the button is clicked, the _TextChanged Event Fires,
turning it red.
Thanks,
Seth Rowe

TextBox1_TextCh anged(me.TextBo x1, EventArgs.Empty )

I don't see this behavior. From what I know, the TextChanged event
will be called whenever you change the text, regardless if by your
code or from the UI...
Maybe you need to describe your exact problem.

Whoa! You are absolutely right! Thanks for the information, Seth!
What I am doing in response to the text changed event is determining
if the file that is typed into it exists or not (yes, I know, there
could be issues with slowing down the GUI with networks, etc., but
this is just a quick 'n dirty application, so it's ok for now).
So, obviously my code is being run, but the code that is being run
isn't working. Which is strange, since I am initializing the text box
to contain text of an existing file. If I change one character in it,
and then undo that change, (i.e. causing the USER to create the exact
text that the program does), my code will work! Hmm... must be
something to do with the Form1_Load() event... I'll mess around and
post back in a bit...

Thanks again, Seth. You're a great help.

Branco, I would have included more information at the start, but I
didn't think it was relevant.
I simply goofed... The response to the TextChanged() event was to see
if the filename typed in existed or not, and respond with a visible
reaction. It appears something else was overriding that initial
programmatic reaction (in Form1_Load), so I didn't see it. It was
working all along... <sigh>
You guys have been a great help. Thanks again!

Hi all,
I have a combobox control, in wich I put an autocomplete code. This code is
in the TextChanged event, but when this event fires, the Text property isn't
updated yet.
For example, if the Text property is "Foo" and I press the letter "d", the
Text property when the TextChanged event runs is "Foo". Only after the
TextChanged event be processed, the KeyDown, KeyUp and KeyPress events fires
and update the Text property.

Hi all,
I am trying to make a UserControl with a TextBox in it.
I have to publish the TextChanged event of the inner TextBox, but I have
some trouble.
If I declare :
public event EventHandler TextChanged;
I get a compiler error saying that TextChanged is already declared and I
have to use :
public new event EventHandler TextChanged;
