  • How to preview any files inside a Java application ?

    - by Studer
    I'm using a JTree to browse the content of a folder and I want that when a user click on a file, the software shows a preview of it (a screenshot of its first page). The files are mostly Office documents and PDF. I manage to do it for PDF file using a module downloaded from Sun, but I'd like to know if there is a way to do it using any software (JARs preferably) or even the built-in Windows API. I was thinking of converting the file to PDF then do a preview of this PDF but this isn't optimal. Any ideas ?

  • Zend Framework - Can view helpers be user inside of partials?

    - by Bob Spryn
    Working on implementing view helpers and partials to create a group of reusable display objects. Previously addressed in my question here: http://stackoverflow.com/questions/2389531/zend-framework-when-to-use-viewscripts-partials-vs-view-helpers Wondering if partials can call view helpers of their own, and if they can whether those helpers will have access to the original view (since the partials don't).

  • How to use a 3rd party control inside the viewmodel?

    - by Sander
    I have a 3rd party control which among other things performs loading of some data. I want my viewmodel to keep track of this load operation and adjust its own state accordingly. If it were up to me, I'd do the data loading far away from the view, but it is not. So, I seem to be in the situation where my viewmodel depends on my view. How do I best handle this? I feel rather dirty making the view publish events to the viewmodel but I don't see any other reasonable way to get this info into the viewmodel. A similar situation might crop up with standard controls, too - imagine if your viewmodel depends on the events coming from a MediaElement - how do you properly model this? Do you put the MediaElement into the viewmodel? That doesn't sound right. If publishing the events to the viewmodel is indeed the most reasonable way, is there some common pattern used for this? How do you do it?

  • How to have type hinting in PHP that specifies variable scope inside of a template? (specifically PhpStorm)

    - by Lance Rushing
    I'm looking for a doc comment that would define the scope/context of the current php template. (similar to @var) Example View Class: <?php class ExampleView { protected $pageTitle; public function __construct($title) { $this->pageTitle = $title; } public function render() { require_once 'template.php'; } } -- <?php // template.php /** @var $this ExampleView */ echo $this->pageTitle; PHPStorm gives an inspection error because the access on $pageTitle is protected. Is there a hint to give scope? Something like: <?php // template.php /** @scope ExampleView */ // <---???? /** @var $this ExampleView */ echo $this->pageTitle;

  • Is it possible to center an image on both axis inside a div?

    - by Noor
    I have a script that loads in a div with images running jQuery Cycle Lite Plugin. I got the tip that I could us the "after" function in that plugin to make changes to the picture each time the image is refreshed. So I wrote this: $("#display div").css({ margin: "0 auto", "text-align": "center", }); The html built like this: <div id="display"> <div id="slideshow1"> <img ... /> </div> </div> This isn't working, whats wrong? ( this is supposed to center it horizontally, i need to center it vertically to )..

  • Why does jQuery fadeOut not work inside this setInterval loop?

    - by Clay McClure
    I'm trying to load random items into a div every few seconds, with a nice fadeOut/fadeIn transition between each load. Here's the code: <html> <body> <div id="item"></div> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <script type="text/javascript"> // Load a random item var item = $('#item'); function load_item() { item.fadeOut(5000, function() { item.load('http://dynamic.xkcd.com/comic/random/ #middleContent img', null, function() { item.fadeIn(5000); }); }); }; // Load initial featured item load_item(); // Schedule repeated loading setInterval(load_item, 15000); </script> </body> </html> This works fine the first time through, but on subsequent calls to load_item, the fadeOut() seems to stop working. It doesn't actually fade the #item div out, but jumps immediately into the callback function, ignoring the 5000 delay. What am I doing wrong?

  • How can invoke a shell to make a new environment to run a make inside another make?

    - by WilliamKF
    I would like in my GNUmakefile to have a target rule that invokes a new shell and then with the clean slate of the new shell invokes a new make. What is the syntax to do this? I tried this but it didn't work: .PHONY: setup setup: shell cd myDir; make; cd .. It gets infinite repeat of the following error: make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found [...]

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • I need to know inside of "while(fscanf != EOF){blah}" if the next fscanf is going to return EOF-- be

    - by Rancur3p1c
    I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered something like this before and has a cleaner solution.

  • can I acces a struct inside of a struct without using the dot operator?

    - by yan bellavance
    I have 2 structures that have 90% of their fields the same. I want to group those fields in a structure but I do not want to use the dot operator to access them. The reason is I already coded with the first structure and have just created the second one. before: struct{ int a; int b; int c; object1 name; }str1; struct{ int a; int b; int c; object2 name; }str2; now I would create a third struct: struct{ int a; int b; int c; }str3; and would change the str1 and atr2 to this: struct{ str3 str; object1 name; }str1; struct { str3 str; object2 name; }str2; Finally I would like to be able to access a,b and c by doing: str1 myStruct; myStruct.a; myStruct.b; myStruct.c; and not: myStruct.str.a; myStruct.str.b; myStruct.str.c; Is there a way to do such a thing. The reason for doing this is I want keep the integrety of the data if chnges to the struct were to occur and to not repeat myself and not have to change my existing code and not have fields nested too deeply.

  • Interpolating height for a point inside a grid based on a discrete height function.

    - by fastrack20
    Hi, I have been wracking my brain to come up with a solution to this problem. I have a lookup table that returns height values for various points (x,z) on the grid. For instance I can calculate the height at A, B, C and D in Figure 1. However, I am looking for a way to interpolate the height at P (which has a known (x,z)). The lookup table only has values at the grid intervals, and P lies between these intervals. I am trying to calculate values s and t such that: A'(s) = A + s(C-A) B'(t) = B + t(P-B) I would then use the these two equations to find the intersection point of B'(t) with A'(s) to find a point X on the line A-C. With this I can calculate the height at this point X and with that the height at point P. My issue lies in calculating the values for s and t. Any help would be greatly appreciated.

  • C Program Stalls or Infinite Loops inside and else statement?

    - by Bobby S
    I have this weird thing happening in my C program which has never happened to me before. I am calling a void function with a single parameter, the function is very similar to this so you can get the jist: ... printf("Before Call"); Dumb_Function(a); printf("After Call"); ... ... void Dumb_Function(int a){ if(a == null) { } else{ int i; for(i=0; i<a; i++) { do stuff } printf("test"); } } This will output Before Call test and NOT "After Call" How is this possible? Why does my function not return? Did my program counter get lost? I can not modify it to a non void function. When running the cursor will blink and I am able to type, I press CTRL+C to terminate. Any ideas?
