  • Take user input and write to file from javascript inside a pdf?

    - by dazedandconfused
    Is it possible to have a pdf file that asks a user a set of questions and then writes their answers to a file, then next time it is viewed loads those answers as default values? I know pdfs can include javascript and have figured out how to add javascript to a pdf with iText (http://itextpdf.com/) but don't know how to prompt for user input or write to a file from inside the pdf. Any help would be appreciated.

  • How to check for redirects on ajax calls?

    - by acidzombie24
    I was looking at this answer and some other answers http://stackoverflow.com/questions/199099/how-to-manage-a-redirect-request-after-a-jquery-ajax-call/199156#199156 I can not get this to work. i check the XMLHttpRequest object in both success and complete. In both cases when there is a redirect instead of getting a 302 i get a 200 and the html for that page. How do i make it actually report the 3xx redirect instead of skipping ahead and giving me a 200?

  • What runs before main()?

    - by MikimotoH
    After testing on msvc8, I found: Parse GetCommandLine() to argc and argv Standard C Library initialization C++ Constructor of global variables These three things are called before entering main(). My questions are: Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform? What stuff does Standard C Library initialization do? So far I know setlocale() is a must. Is it safe to call standard C functions inside C++ constructor of global variables?

  • Learning C++ on Linux or Windows?

    - by ReDAeR
    Hi, Since you 'should' learn C/C++ and as part of 'learn as much languages as possible', i decided to learn C++ in depth. My OS is Windows and my question is should i re-install Linux as a dual boot to learn C++ on Linux? Do i miss something if I develop in C++ only on the Windows platform?

  • Why does Convert.ToBoolean("0") fail?

    - by JL
    I know that trying to convert string "0" to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions. What I would like to know is WHY does C# not recognize "0" as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input "0" as valid.

  • jQuery center multiple dynamic images in different sized containers

    - by JVK Design
    So I've found similar questions but none that answer all the questions I have and I know there must be a simple jQuery answer to this. I've got multiple images that are being dynamically placed in their own containing div that have overflow:hidden, they need to fill their containing divs and be centered(horizontally and vertically) also. The containing divs will be different sizes as well. So in short: multiple different sized images fill and center in containing div. containing divs will be different sizes. will be used multiple times on a page. Hopefully this image helps explain what I'm after. Click here to view the image. HTML I'm using but can be changed <div class="imageHolder"> <div class="first SlideImage"> <img src="..." alt="..."/> </div> <div class="second SlideImage"> <img src="..." alt="..."/> </div> <div class="third SlideImage"> <img src="..." alt="..."/> </div> </div> And the CSS .imageHandler{ float:left; width:764px; height:70px; margin:1px 0px 0px; } .imageHolder .SlideImage{ float:left; position:relative; overflow:hidden; } .imageHolder .SlideImage img{ position:absolute; } .imageHolder .first.SlideImage{ width:381px; height:339px; margin-right:1px; } .imageHolder .second.SlideImage{margin-bottom:1px;} .imageHolder .second.SlideImage, .imageHolder .third.SlideImage { width: 382px; height: 169px; } Ask me anything if this doesn't make sense, thanks in advance
