  • Do you think its user unfriendly to show error message in tooltips ?

    - by msfanboy
    Hello, when my user enters data validated as wrong a red circle with a white exclamation mark is shown in the right part of the textbox with the wrong data. The error message is only shown when the user hovers the textbox with wrong data. Do you think that is a bad User experience ? I could show the red error message text to the right side of the textboxes if there would still be space...

  • Unix: replace every odd | with \left| and every even | with \right|

    - by HH
    An enormous equation. You need to add \left| on the left side of corresponding |. The corresponding | you need to replace with \right|. Equation \begin{equation} | \Delta w_{0} | = \frac{|w_{0}|}{2} \left( |\frac{\Delta g}{g}|+|\frac{\Delta (\Delta r)}{\Delta r}| + |\frac{\Delta r}{r}| +|\frac{\Delta L}{L}| \right) \end{equation}

  • VS2010 has been released, so what do you hate or love about it?

    - by csharptest.net
    I recently installed the release version of Visual Studio 2010. So far I'm less than impressed with the rewrite and was wondering if I'm the only one. The thing I dislike the most is the inability to use the old-school MDI windows instead of the dreaded tabbed documents. For the other side the usage generator seems like it may prove useful in time. So what do you like or dislike about the changes to VS2010?

  • HTML/CSS Rendering to Image

    - by Steve
    Is there a library or tool that can take an html page and some css, and then render an image? I would like to define some templates server side using html code snippets, and some CSS to define the layout. Then using the template and CSS, I would like to essentially render an image of how this would display in a browser, and pass the image back to the client. Thanks.

  • How does CSS 3 border-image work exactly?

    - by Tower
    Hi, I have an image of 4x4 in size and I want to use it all around a DIV's border. The following: -moz-border-image: url("../images/window/side.png") 4 4 4 4 / 4px 4px 4px 4px repeat repeat will place left and right borders, but not bottom and top. What's wrong with it? I think I have misunderstood the syntax and if that is so, how does this syntax really work?

  • Can I use a filehandle instead of a filename for creating DBM files?

    - by Dancrumb
    I'm using MLDBM to persist some Perl data structures and I'm wondering if there's an alternative to the following: tie %hash, "MLDBM", $dbm_file, O_CREAT | O_RDWR, 0644; Primarily, I'd like to be able to use STDOUT, rather than a known file name. This could then be redirected to a file on the shell-side. I've been searching with keywords like "tie", "DBM" and "filehandle", but the hits tend to talk about tying filehandles to things, as opposed to things to filehandles. Any suggestions?

  • Polymorphic association inserts 0 instead of raising error when column is misconfigured as Integer

    - by zetetic
    Here's one that stumped me for a while, though in retrospect it should have been obvious. I was getting the error message NoMethodError: undefined method `constantize' for 0:Fixnum when accessing a model through a polymorphic association. Turns out the table on the belongs_to side of the association had an integer type column instead of a string. Easily fixed, but it seems like Rails ought to raise an error in this situation -- instead it happily adds the row with 0 in the type column.

  • What javascript templating engine do you recommend?

    - by flybywire
    Do you have experience with a Javascript templating engine, one that is stable, easy to use and has good performance? I need to do apply the same template many times for different data. I prefer to download the template itself once (and have it cached) rather than processing the template on the server. Also, this way the template itself would be a static resource more easily cached in the server side too.

  • Form with list of checkboxes (best practices)

    - by boris callens
    I have a view that allows the user to make a selection from an IEnumerable. The way I'm doing it now is to give each checkbox the id of the item and work with the form collection at the controller's side. I seem to remember there to be a better way but can't remember how anymore. Are there any better practices?

  • How do I conditionally redirect the output of a command to /dev/null?

    - by Lawrence Johnston
    I have a script. I would like to give this script a quiet mode and a verbose mode. This is the equivalent of: if $verbose then redirect="> /dev/null" fi echo "Verbose mode enabled" $redirect # This doesn't work because the redirect isn't evaluated. I'd really like a better way of doing this than writing if-elses for every statement affected. eval could work, but has obvious side effects on other variables.
