  • Creating JMS Queues at runtime.

    - by ankur
    I am working on an application where the app user can create / delete queues . Also , he would be able to move a message from 1 queue to another, delete a message , rearrange the messages in the queue based on some filter. One possible design is to use activemq for queues and apache camel for various other operations having integrated with Grails. But I am not sure whether ActiveMQ allows creation /deleltion queues at runtime. Would this be a good choice to implement such system?

  • Excel embedded in a php page

    - by Brian
    I have a client who wants to be able to embed an Excel document (one that is currently sitting on the same server as the HTML document) like how you would embed a Flash app on a page. I'm correct in assuming this is not possible, right? Please confirm/deny so we can hopefully move on from this because he seems to think this is possible. We are on a LAMP setup so no .NET tricks, unfortunately.

  • Livevalidation clientside validation - can you control the position of the validation messages?

    - by JK
    I'm using LiveValidaion for my clientside validation http://livevalidation.com/ and DataAnnotations for my validation rules. This all works fine except that the clientside error messages are only ever displayed to the right of the element being validated. Is it possible to move this validation message below the element being validated? Or even better, group all messages in a div at the top/bottom of the page? I dont see anything in their docs or examples

  • how can I change top-margin the right way if multiple css class assigned?

    - by Radek
    I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down. I did so by .menu_about_author { margin-top:40px; } but it didn't work any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png

  • Why do my horizontal toolstrips keep stacking verticaly?

    - by Eric
    I'm using a ToolStripContainer that contains three ToolStrips. At design time I move the ToolStrips to the positions I want them in, which is in a horizontal row across the top of the form like this: I then close and save the Form. However, if I open the form up again the ToolStrips end up stacked up on the left side of the ToolStripContainer like this: How can I keep the ToolStrips in the positions that I specify?

  • What is the best way to create continuously looping background in iPhone SDK ?

    - by catpad
    What is the best way to create a continuously looping background using iPhone SDK so that it seems the foreground object is in perpetual motion ? I have a background image which I want to move continuously at a given speed from right to left and seamlessly start displaying the beginning of the image when its end is reached. What is the best, most efficient way to do it to avoid any jumps and get optimal performance ?

  • JavaFX2: Drag Event start and end coordinates

    - by user
    I have one node(ImageView) that displays an image and another node(rectangle) that resides on top of it. The behavior I need is that when the mouse is dragged(press-drag-release gesture) over the rectangle, both the nodes should move coherently. My thought process goes in the following direction: • Move both the nodes by the same distance in the direction of the drag. For this option(maybe there are more options) I need the distance between the start and end of the mouse drags. I tried capturing the start and end coordinates of the drag but have been unsuccessful. I think I am getting lost in which handlers to implement. The code I have is below: import javafx.event.EventHandler; import javafx.geometry.Rectangle2D; import javafx.scene.image.ImageView; import javafx.scene.input.MouseEvent; public class MyView { double mouseDragStartX; double mouseDragEndX; double mouseDragStartY; double mouseDragEndY; ImageView imageView; public MyView() { imageView = new ImageView("C:\\temp\\test.png"); } private void setRectangleEvents(final MyObject myObject) { myObject.getRectangle().setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { mouseDragStartX = mouseEvent.getX(); mouseDragStartY = mouseEvent.getY(); mouseEvent.consume(); } }); myObject.getRectangle().setOnMouseReleased(new EventHandler<MouseEvent>() { public void handle(MouseEvent mouseEvent) { mouseDragEndX = mouseEvent.getX(); mouseDragEndY = mouseEvent.getY(); myObjectDraggedHandler(); } }); } private void myObjectDraggedHandler() { Rectangle2D viewport = this.imageView.getViewport(); double newX = this.imageView.getImage().getWidth() + (mouseDragEndX - mouseDragStartX); double newY = this.imageView.getImage().getHeight() + (mouseDragEndY - mouseDragStartY); this.imageView.setViewport(new Rectangle2D(newX, newY, viewport.getWidth(), viewport .getHeight())); } } P.S: This code is just for indicating what I am trying to implement and will not compile correctly. Or maybe my question should just have been: How to capture the length or span of a mouse drag?

  • Moving mysql files across servers

    - by tesmar
    I have a massive MySQL database (around 10 GB), and I need to copy it to a different server (slicehost). I don't want to do a DB dump and reimport b/c I think that would take forever. Is it possible to just move the raw SQL files from one machine to the next, setup an identical mysql server, and flip the switch?

  • Icons/graphics for your applications

    - by rein
    I need to source some graphics/icons for my application I'm writing (Windows WinForms). I need graphics for toolbar buttons, icons for form headers and graphics for wizard dialog boxes. As a last resort I'm willing to create them myself - a move that might make them (and my whole application) look amazingly bad. What are some good sources (free or not) where I can get these kinds of programmer icons? I'd like the icons to be at least 32x32 256 color.

  • fire an intent from the onCreate method in android

    - by Sephy
    Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

I want when I move the slider to move a dot on the chart accordingly with the slider position. See attached screenshot: As you can see it seems to work fine. I've implemented this behaviour using the pathIntersection() method. On the slide event at each ui.value (x coordinate) I intersect my chartPath (the one from above) with a vertical straight line at the x coordinate. But still there are some problems. One of them is that it runs very hard, and it kinda freezes sometimes.. and very weird sometimes it doesn't seem to intersect at all even it should.. I'll example below 2 cases I identified: M 499.8461538461538 0 L 499.8461538461538 140 M 910 0 L 910 140 Could you please explain why this intersect behaviour happens (it should return a dot).. and the worst part it seems like it happens randomly.. if I use another chartdata. Also if you can identify another (better) solution to syncronise the slider position with the dot on the chart.. would be perfect. I thought about using Element.getPointAtLength(length), but I don't know how. I think I should save the pathSegments and for each to compute the start Length and the finish Length.

  • Vim: Smart indent when entering insert mode on blank line?

    - by TheDeeno
    When I open a new line (via 'o') my cursor jumps to a correctly indented position on the next line. On the other hand, entering insert mode while my cursor is on a blank line doesn't move my cursor to the correctly indented location. How do I make vim correctly indent my cursor when entering insert mode (via i) on a blank line?

  • Silverlight MouseMove: find missing points during a movement

    - by Jalfp
    In an application in Silverlight I'm working on, I need to track the moves of the mouse. My problem is that using the MouseMove event, I don't have a continuous set of points if the user moves the mouse fast enough (if I add each point in a list I can have (10,10) en then (20,20)...) I'd like to have ALL points where the mouse has been during the move. Do you have any idea ?
