Before I start this, I want to point out that this isn't a fantastic design. This is the reason you're finding it so difficult. The problem is that C++ is capable of pretty much anything and VB is capable of pretty much anything you really shouldn't do. Wink | ;) [half joking, I'll come back to this later]

It is possible though, and really quite easy.

You need to handle the Enter and Leave events of the SQL Command TextBox and use them to change the AcceptButton of the form.
private void textBox2_Enter(object sender, System.EventArgs e)
{
	this.AcceptButton = button2;
}

private void textBox2_Leave(object sender, System.EventArgs e)
{
	this.AcceptButton = button1;
}
If you would rather not have an AcceptButton for this TextBox but would prefer to trap the KeyDown, you could replace button2 with null. I would suggest this is a really bad idea though, it should be obvious to the user that the AcceptButton has moved.

In the real world (non-educational), I would suggest quite strongly that this whole thing is bad design. In the real world, I would expect a menu containing Connect and Disconnect (only one active at any given time). Connect would give you a dialog for User/Password, Disconnect wouldn't. The only things I'd have in the main form is the SQL Command TextBox and the related AcceptButton.

As a consumer, I wouldn't buy your product designed to be so confusing.

Just a few thoughts.

Hope this helps

Paul
