  - by Cesar Lopez

  I have several select boxes and textboxes with the same class and I have the following statement. if ($('.selTxtClass:visible').val() == "") { $('.selTxtClass:visible').focus(); } } If I do an alert with ($('.selTxtClass:visible').val()) it comes as undefined. I want to check that the value of these elements are empty, but I cant see what is wrong with this if statement, could you give me a hand, please? Thanks a lot.

• Barcode reading method?

  - by Atlas

  I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box. Now my question, how do I configure the scanner and my application, so that my app can process the barcode data directly. That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPress event fires.

• Fade unfocused GNU Emacs frame (X window)

  - by Mischa Arefiev

  Is it possible to make GNU Emacs 24 dim unfocused windows a bit? For example, I can set my rxvt-unicode clients to become darker when their windows don't have focus with this string in ~/.Xdefaults: URxvt*fading: 50 It greatly reduces discomfort when you have a lot of terminal windows on 2+ monitors. I would like a similar feature in Emacs, but couldn't google up anything. Here is how it looks like with urxvt (png, 1.43 MB)

• How can I securely check if a username is already taken?

  - by Geo

  I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

• Change background color when clicked textbox in C#

  - by jweinraub

  I like for the textbox to change the background when the textbox has focus (if clicked with a mouse, tabbed into, etc). I don't like the textchange method since it won't change until one character has been added. private void txtFoo_OnGotFocus(object sender, EventArgs e) { txtFoo.BackColor = Color.LightYellow; txtBar.BackColor = Color.White; } This doesn't seem to work for me. What am I doing wrong?
