  • Hibernate Native Query problem with named parameters

    - by dime
    I have a problem with Hibernate Native Query. I have one SELECT that selects array slice (PostgreSQL database). The problem is that hibernate recognizes the following part: ":300" from "SELECT my_array[1:300]..." as named parameter and I get the following exception: Not all named parameters have been set. I tried to escape the colon (:) with '\:' , '::' but with no success. The Hibernate version is 3.2

  • Adding procedural C openGL functions to an iPhone project

    - by user309595
    I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?

  • How do I assign functions in a dictionary?

    - by Ziv
    hi, I'm having a problem with a simple program I wrote, I want to perform a certain function according to the users input. I've already used a dictionary as a replacement for a switch to do assignment but when I try to assign functions to the dictionary it doesn't execute them... The code: def PrintValuesArea(): ## do this def PrintValuesLength(): ## do that def PrintValuesTime(): ## do third PrintTables={"a":PrintValuesArea,"l":PrintValuesLength,"t":PrintValuesTime} PrintTables.get(ans.lower()) ## ans is the user input what did I do wrong? It looks the same as all the examples I've seen....

  • do you call them functions, procedures or methods?

    - by lowlyintern
    consider a standard c# 'function' public void foo() { //some code } In c or c++ this is called a 'function' - even if taking no parameters and returning no value. In another language maybe it would be a 'procedure'. In object orientation speak it would be called a 'method' if a class member. What would be the correct term to use in c#?

  • Routing optional parameters with dashes in MVC

    - by Géza
    I've made an routing definition like this: routes.MapRoute("ProductSearch", "Search-{MainGroup}-{SubGroup}-{ItemType}", new { controller = "Product", action = "Search", MainGroup = "", SubGroup = "", ItemWebType = ""}); It is not working if the parameters are empty. Actually it resolves the url, so Url.Action method resolves the path "Search-12--" but the link is not working, so the GET of the page is not working With slashes it is working the Url.Action method makes "Search/12" "Search/{MainGroup}/{SubGroup}/{ItemType}" is it somehow possible to correct it?

  • Figuring out QuadCurveTo's parameters

    - by Fev
    Could you guys help me figuring out QuadCurveTo's 4 parameters , I tried to find information on http://docs.oracle.com/javafx/2/api/javafx/scene/shape/QuadCurveTo.html, but it's hard for me to understand without picture , I search on google about 'Quadratic Bezier' but it shows me more than 2 coordinates, I'm confused and blind now. I know those 4 parameters draw 2 lines to control the path , but how we know/count exactly which coordinates the object will throught by only knowing those 2 path-controller. Are there some formulas? import javafx.animation.PathTransition; import javafx.animation.PathTransition.OrientationType; import javafx.application.Application; import static javafx.application.Application.launch; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; import javafx.scene.shape.QuadCurveTo; import javafx.scene.shape.Rectangle; import javafx.stage.Stage; import javafx.util.Duration; public class _6 extends Application { public Rectangle r; @Override public void start(final Stage stage) { r = new Rectangle(50, 80, 80, 90); r.setFill(javafx.scene.paint.Color.ORANGE); r.setStrokeWidth(5); r.setStroke(Color.ANTIQUEWHITE); Path path = new Path(); path.getElements().add(new MoveTo(100.0f, 400.0f)); path.getElements().add(new QuadCurveTo(150.0f, 60.0f, 100.0f, 20.0f)); PathTransition pt = new PathTransition(Duration.millis(1000), path); pt.setDuration(Duration.millis(10000)); pt.setNode(r); pt.setPath(path); pt.setOrientation(OrientationType.ORTHOGONAL_TO_TANGENT); pt.setCycleCount(4000); pt.setAutoReverse(true); pt.play(); stage.setScene(new Scene(new Group(r), 500, 700)); stage.show(); } public static void main(String[] args) { launch(args); } } You can find those coordinates on this new QuadCurveTo(150.0f, 60.0f, 100.0f, 20.0f) line, and below is the picture of Quadratic Bezier

  • Using functions and environments

    - by Eduardo Leoni
    Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  • JavaScript Self Executing Functions - What's the Difference?

    - by modernzombie
    I am very familiar with self executing functions from working with jQuery. (function($) { /* do stuff */ })(jQuery); Today I was reading the backbone.js source and noticed that they do this: (function() { /* do stuff */ }).call(this); Is this achieving the same thing? Would the following 2 lines of code do the same thing? (function($) { /* do stuff */ })(jQuery); (function($) { /* do stuff */ }).call(jQuery);

  • referencing desired objects in namespaced functions

    - by RyOnLife
    I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

    Using jQuery's 'submit' - is there a way to pass additional parameters to a form? I am NOT looking to do this with Ajax - this is normal, refresh-typical form submission. $('#submit').click(function () { $('#event').submit(function () { data: { form['attendees'] = $('#attendance').sortable('toArray').toString(); }); });

Any suggestions?
