  • Choosing the right template engine

    - by asrijaal
    Hi there, since today - I always used simple JSP Tags and JSTL which works but now I'm looking for a little bit more features and maybe more usability. With googling I've found Freemaker, Velocity and Tiles which seem to be very famous. Does someone of you has some further experiences with some of these and can give me a short brief about it. Or are there other frameworks which are worth to look into?

  • C printf in Delphi?

    - by kroimon
    Hi there! Does anyone know a 100% clone of the C/C++ printf for Delphi? Yes, I know the System.Format function, but it handles things a little different. For example if you want to format 3.14 to "003" you need "%03d" in C, but "%.3d" in Delphi. I have an application written in Delphi which has to be able to format numbers using C format strings, so do you know a snippet/library for that? Thanks in advance!

  • MainMenu with Images (WinForms, C#)

    - by j-t-s
    Hi All I have a MainMenu in my app and I would like to have little icons relevant to the Item in each menu. But the MainMenu control does not support this. I would use the MenuStrip control, though that is a pretty ugly option in my opinion. Does anybody have any suggestions? Are there any free/open source alt's out there, or would it be easy/possible to implement that feature into the existing MainMenu control? Thanks

  • Flex AdvancedDatagrid inline commentary functionality required

    - by Forkrul Assail
    I'm using Flex's Advanced Datagrid for a project and need inline comments, in a similar style to Excel spreadsheet comments. A little visual indicator should indicate if a field is associated with a comment, and on clicking on the element should open or trigger an action for displaying that particular comment. Any suggestions on how I would go about implementing this?

    - by wolfi
    Hey everybody, is there a way to get the logged in user name (and group) from a Tomcat system. I read something about configuring Tomcat, so it is getting the user information out of a database. But I found now information about getting the name of the user (in my GWT Project), which is logged in. I'm trying to write a little GWT project and would like to publish the user name to the front page. Thx for your help.

  • What's the difference between reflow and repaint?

    - by Jon Raasch
    I'm a little unclear on the difference between reflow + repaint (if there's any difference at all) Seems like reflow might be shifting the position of various DOM elements, where repaint is just rendering a new object. E.g. reflow would occur when removing an element and repaint would occur when changing its color. Is this true?

  • HTML: how to create a "save as" button?

    - by user68759
    In your browser, when you want to save an HTML page that you are currently viewing, you normally go to the File menu and click Save As. Can I have a little button at the bottom of an HTML page that does the same thing? So instead of going to the File menu - Save As, I want my user to be able to click the button to save the page on to the disk. There is a solution exists using Javascript as far as I know, but it only works for IE. See here: link text

  • When to use a namespace or a struct?

    - by Justen
    I was just reading a little bit on them from http://www.cplusplus.com/doc/tutorial/namespaces/ and it seems like a struct is capable of the same things? Or even a class for that matter. Maybe someone here can better define what a namespace is, and how it differs from a struct/class?

  • Generate SQL script to insert XML from files, using Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.

  • xpath: string manipulation

    - by Jindan Zhou
    So in my scrapy project I was able to isolate some particular fields, one of the field return something like: [Rank Info] on 2013-06-27 14:26 Read 174 Times which was selected by expression: (//td[@class="show_content"]/text())[4] I usually do post-processing to extract the datetime information, i.e., 2013-06-27 14:26 Now since I've learned a little more on the xpath substring manipulation, I am wondering if it is even possible to extract that piece of information in the first place, i.e., in the xpath expression itself? Thanks,

I know this question is very non-specific, but I am looking for best practices/guidelines here. Thanks in advance.

  • `var = something rescue nil` behaviour

    - by JP
    In ruby you can throw a rescue at the end of an assignment to catch any errors that might come up. I have a function (below: a_function_that_may_fail) where it's convenient to let it throw an error if certain conditions aren't met. The following code works well post = {} # Other Hash stuff post['Caption'] = a_function_that_may_fail rescue nil However I'd like to have post['Caption'] not even set if the function fails. I know I can do: begin post['Caption'] = a_function_that_may_fail recsue end but that feels a little excessive - is there a simpler solution?
