  • java servlet: generate zip file from BLOBs

    - by Zack
    I'm trying to zip a large number of pdf files (stored as BLOBs in the DB) and then return the zip as an attachment to the user. What's the best way to do this without running into memory issues? Another note: I actually need to merge some PDFs prior to adding them to the ZipOutputStream. Therefore, a couple PDFs will need to be stored in memory at a time. I assume it would be best to then store them as temporary files on the server before zipping them all?

  • Is it possible / recommendable sending HTML emails containing Javascript?

    - by Adriano Varoli Piazza
    This is mostly a rhetorical question, as far as I've checked the answer is 'don't even bother', but I wanted to be really sure. We have an email app, where you can send email to lists of subscribers. This is not spam: it's used, for example, by an university to send communications to its students, by a museum to send emails to subscribers, etc. Recently, I was asked by a prospective client if it was possible to send html messages containing javascript without being marked as spam. Not knowing, I did a short trip of the webs and what I've got is (percentages out of my posterior) 'half the clients won't display properly', 'half the clients will flag you as spam' and 'half the clients will have blocked javascript altogether' (There's clearly some superposition). So the best solution seems to be adding a link to a proper page if really necessary. Have you got a different experience? Do you know of any email-merge solution that provides this feature? Do you know if specific clients accept it or refuse to display html with javascript?

  • Displaying image with php

    - by Hank Denijm
    I have a script which displays images like this: header("Content-Type: image/{$ext}"); readfile($image-path); This has worked fine for weeks and now suddenly it has stopped working. The response header looks fine (Content-Type: image/jpg), I have no ending php-tag and I have made no changes to my code, server- or php-setup which could have caused this to malfunction. Does anyone have a clue as to what may be going wrong? Thanks!

  • Disable the postback on an <ASP:LinkButton>

    - by y0mbo
    I have an ASP.NET linkbutton control on my form. I would like to use it for javascript on the client side and prevent it from posting back to the server. (I'd like to use the linkbutton control so I can skin it and disable it in some cases, so a straight up tag is not preferred). How do I prevent it from posting back to the server?

  • php search and replace

    - by Dave
    I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

  • Integrate ClickOnce update in a setup

    - by Erick
    As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

  • Resources for Windows Phone 7 development

    - by geocoin
    Windows Phone 7 has just been unveiled and right now there is no publicly available information to non-privileged developers/partners. MS are announcing all details of the development chain at the Mix10 conference. So until then this could be a good starting point/collection of online resources as they appear EDIT: I've added the speculation tag so we can also accumulate speculation. Please mark speculative posts as such. once firm details are announced we can confirm or delete them

  • CSS selectors : should I minimise my use of the class attribute in the HTML or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It also make my .css file a little harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?
