Control wont take focus

[=?Utf-8?B?dmJ0cnlpbmc=?=]

I am using a switch statement, to check for valid user hours. If the hours
control is blank, I want to place the cursor back to the hours control for
the user.

The following code does NOT work:

switch (txtHours.Text)
{
case "":
MessageBox.Show("No hours entered.\nYou must enter hours
for this record.", "Bad Value for Hours", MessageBoxButtons.OK,
MessageBoxIcon.Error);
txtHours.Focus();
break;
default:
break;
}

Has anybody tried to do this before? Am I using it incorrectly?

Thanks,
Terry

How does it "NOT work"? Where do you execute the code?

The Focus() method does generally work, and I have in fact used it when
doing textbox value validation. So the general technique is sound.

But if you aren't putting the code somewhere that guarantees that the
focus will be left alone after you call Focus(), you could easily wind
up not seeing any focus change.

You need to be more specific if you want an answer though. You should
post a concise-but-complete example of code that reliably reproduces the
problem (and of course, you should be more precise in describing the
problem than "does not work").

Pete, get off your high horse guy! "You need to be more specific if you want
an answer". Don't answer if you think the question doesn't suite your needs
as fas as clarity.

You are the reason bulletin boards don't work.

I'm not so sure of that. I suspect that you will think a lack of a
response on my part is due to an inability to answer the question, when
in fact it would be due to the lack of an apology from you for your
behavior.

If my suspicion is correct, then you don't understand.

I guess we'll see.

Don't wait too long for an apology from me. If you can't answer the question,
or just don't want to, fine. But don't hide behind the premise that you're
waiting for an apology first before you answer questions.

You must enjoy the world you live in.

Why would I wait at all? Rest assured, I'm not sitting around waiting
for you to do anything at all.

If you can't answer the question,
or just don't want to, fine.

As if you could direct me otherwise?

But don't hide behind the premise that you're

Hide? Um, whatever.

I do, actually. I live in a world where I have no reason to put up with
jerks who fly off the handle at the least possible provocation, taking
insult where none was intended, and who cannot be bothered to apologize
for their atrociously childish behavior.

Your question is not really that hard. You should think carefully about
why it is no one else has jumped in to help you out. It's not like
people are falling over themselves to answer your question. And the
lack of replies is not because it's too hard for everyone else.

Childish behavior, um, let me see. Could it be that you have a "need" to get
the last word in?

Nope. How about you?
