  • Firefox error for signalR, but does not effect anything

    - by anthonypliu
    I get the 2 following errors in firefox when using signalR and I do not know why: Timestamp: 10/15/2012 3:53:48 PM Error: The connection to http://localhost:81/signalr/connect?transport=serverSentEvents&connectionId=84a7f433-0cc8-4baf-93e9-d4c3ca968466&connectionData=%5B%7B%22name%22%3A%22Chat%22%7D%5D&tid=7 was interrupted while the page was loading.

  • Qt: Styling QTabWidget

    - by Martin
    I'm using Qt and I have a QTabWidget setup in the Qt Designer Editor, you can see it in picture 1. As you can see after Tab4 there is an empty space all the way to the right edge, in someway I need to fill that space with a color, like in picture 2. Or another solution would be that the tabs float out to cover the whole screen. I use the following stylesheet right now: QTabWidget::tab-bar { } QTabBar::tab { background: gray; color: white; padding: 10px; } QTabBar::tab:selected { background: lightgray; } Is there a way to set the background color of the QTabBar using Qt stylesheets? Or can I get the tabs floating out to the edge using Qt stylesheets? Thanks!

  • Resize AIR app window while dragging

    - by matt lohkamp
    So I've noticed Windows 7 has a disturbing tendency to prevent you from dragging the title bar of windows off the top of the screen. If you try - in this case, using an air app with a draggable area at the bottom of the window, allowing you to push the top of the window up past the screen - it just kicks the window back down far enough that the title bar is at the top of what it considers the 'visible area.' One solution would be to resize the app window as it moves, so that the title bar is always where windows wants it. How would you resize the window while you're dragging it, though? Would you do it like this? dragHitArea.addEventListener(MouseEvent.MOUSE_DOWN, function(e:MouseEvent):void{ stage.nativeWindow.height += 50; stage.nativeWindow.startMove(); stage.nativeWindow.height -= 50; }); see what's going on there? When I click, I'm doing startMove(), which is hooking into the OS' function for dragging a window around. I'm also increasing and decreasing the height of the window by 50 pixels - which should give me no net increase, right? Wrong - the first '.height +=' gets executed, but the '.height -=' after the .startMove() never runs. Why? update - If you're curious, I'm programming an air widget with fly-out menus which expand rightwards and upwards - and since those element can only be displayed within the boundaries of the application window itself (even though the window is set to be chromeless and transparent) I have to expand the application's borders to include the area that the menu 'pops up' into. In the extreme case, with the widget positioned bottom left, and the menus expanded completely across to the right side and top edge of the screen, the application area could very well cover the entire desktop. The problem is, when it's expanded like this, if the user drags it up and to the right, it causes the 'title bar' area of the application window to move above the top edge of the desktop area, where it would normally be unreachable; and Windows automatically re-positions the window back below that edge once the .startMove() operation is completed. So what I want to do is continually resize the height of the application so that the visual effect will be the same for the user, but for the benefit of the operating system the window's title bar will never be above that top boundary of the desktop area.

  • Eliminating cyclic flows from a graph

    - by Jon Harrop
    I have a directed graph with flow volumes along edges and I would like to simplify it by removing all cyclic flows. This can be done by finding the minimum of the flow volumes along each edge in any given cycle and reducing the flows of every edge in the cycle by that minimum volume, deleting edges with zero flow. When all cyclic flows have been removed the graph will be acyclic. For example, if I have a graph with vertices A, B and C with flows of 1 from A?B, 2 from B?C and 3 from C?A then I can rewrite this with no flow from A?B, 1 from B?C and 2 from C?A. The number of edges in the graph has reduced from 3 to 2 and the resulting graph is acyclic. Which algorithm(s), if any, solve this problem?

  • Delays in .net app when connecting to oracle db using Oracle.DataAccess

    - by chris
    I have a .net desktop app that connects to an oracle database. At times, there are very noticable delays. I ran a trace on the code, and it was always in the DataReader.Read(). I turned on sql tracing, and found the following, which corresponds to the delays I'm seeing: (2128) [23-MAR-2010 13:00:07:310] nsprecv: reading from transport... (2128) [23-MAR-2010 13:00:07:310] nttrd: entry (2128) [23-MAR-2010 13:00:24:655] nttrd: socket 676 had bytes read=2047 (2128) [23-MAR-2010 13:00:24:655] nttrd: exit (2128) [23-MAR-2010 13:00:24:655] nsprecv: 2047 bytes from transport There's about a 14 second pause in there. I'm pretty sure that there's not a problem in the code, but not sure where to look at next. Is there anyone out there with experience with oracle trace that can explain what's going on?

  • PHP: creating a smooth edged circle, image or font?

    - by Chad Whitaker
    I'm making a PHP image script that will create circles at a given radius. I used: <?php imagefilledellipse ( $image, $cx, $cy, $w, $h, $color ); ?> but hate the rough edges it produces. So I was thinking of making or using a circle font that I will output using: <?php imagettftext ( $image, $size, $angle, $x, $y, $color, 'fontfile.ttf', $text ); ?> So that the font will produce a circle that has a smooth edge. My problem is making the "font size" match the "radius size". Any ideas? Or maybe a PHP class that will produce a smooth edge on a circle would be great! Thank you.

  • AspectFit Not Working for Transformed UIImageView

    - by Dex
    I have a UIImageView inside a subview and I'm trying to get an AspectFit content mode working how I want for a 90 degree transformation. Here is a demo app of what I mean https://github.com/rdetert/image-scale-test If you run the app and hold it in a landscape orientation (app runs in landscape) you'll see that the image does not stretch from left edge to right edge. What seems to be happening is that the AspectFit works correctly for the portrait/default orientation, but then the image simply gets rotated the image after the fact. How can I make it auto stretch? I think the fact that it is inside a subview may have something to do with it?

  • Writing the code by dividing it into more files in cocoatouch.

    - by srikanth rongali
    My problem is, I need a background image, a sprite(with animation) on left edge, another sprite(with animation) at other edge, a number count animation 1-2-3 at middle. I got all these when I wrote all in same file.(like [self addChild:label], [self addChild:sprite].., But in this it needs touch enables for both sprites separately, and touchDisabled to the remaining screen. So thought of writing in different files. But now it is not working. I kept one sprite, background image, numbercount in one file and another spritr in other file. Either I am getting the second sprite or the (sprite+background+numberCount) is displayed. This is my problem. plz give me solution. Thank You

  • Stuck on solving the Minimal Spanning Tree problem.

    - by kunjaan
    I have reduced my problem to finding the minimal spanning tree in the graph. But I want to have one more constraint which is that the total degree for each vertex shouldnt exceed a certain constant factor. How do I model my problem? Is MST the wrong path? Do you know any algorithms that will help me? One more problem: My graph has duplicate edge weights so is there a way to count the number of unique MSTs? Are there algorithms that do this? Thank You. Edit: By degree, I mean the total number of edges connecting the vertex. By duplicate edge weight I mean that two edges have the same weight.

  • Blackberry wifi connection issue

    - by AmitG
    Hi all, I have a very strange issue with my blackberry application. My application first searches for a blackberry network ( ;interface=wifi , ;deviceside=true , ;deviceside=false" + ";ConnectionUID="+ myRecord.getUid() ) transport and after finding one, it uses it to connect the server application. The issue is that some of my web services consumed by the bb client applicaton does not work when the connection type is wifi. Example: I have a series of web services called one after the other, login , x , y ,z, and logout. The connection transport selected = WIFI Login and LogOfff works fine but x, y and z web services return me an error message. The same series of web services ( Login, x,y,z, Log Out,) works with other connection transports ( eg. ap2trans) . Please help me with this issue as connecting to wifi ( if available ) is important for the application. Pleaes provide even the smallest info in this regad. thanks in advance

  • How to use AutoLayout to position UIButtons in horizontal lines?

    - by thomers
    I need to create a couple of UIButtons programmatically in my app (iOS 6.0 and above). Each button should have the optimal width to display button label text (of various lenghts). I want to display the buttons in a "wrap around" style: Starting from the left edge, each button should be positioned next to each other horizontally (in a defined order), and if a button does not fit in the current "line", it should start a new line on the left edge below the previous line. I could manually calculate the frame of each button in my code, but should I use AutoLayout (with programmatically creates NSLayoutConstraints) instead? How exactly would I need to set it up?

  • Shortest distance between points on a toroidally wrapped (x- and y- wrapping) map?

    - by mstksg
    I have a toroidal-ish Euclidean-ish map. That is the surface is a flat, Euclidean rectangle, but when a point moves to the right boundary, it will appear at the left boundary (at the same y value), given by x_new = x_old % width Basically, points are plotted based on: (x_new, y_new) = ( x_old % width, y_old % height) Think Pac Man -- walking off one edge of the screen will make you appear on the opposite edge. What's the best way to calculate the shortest distance between two points? The typical implementation suggests a large distance for points on opposite corners of the map, when in reality, the real wrapped distance is very close. The best way I can think of is calculating Classical Delta X and Wrapped Delta X, and Classical Delta Y and Wrapped Delta Y, and using the lower of each pair in the Sqrt(x^2+y^2) distance formula. But that would involve many checks, calculations, operations -- some that I feel might be unnecessary. Is there a better way?

  • index was outside the bounds of the array because of \n (new line) in richTextBox

    - by revvs
    If i go into the next line with richTextBox1.Text + "\n" you can't use richTextBox with anything anymore normally. Why not ? because index will be outside the bounds of the array and you won't be able to transport the data into database or work with it normally...it will be all messed up. It is like the story with cin and getline in C++, but much worse. Here you won't see errors, not until you'll try to transport it into database. If you use "\n" to write new lines into txt, your txt will be also unusable. It will look like up to the byte the same as if you would write it by hand same sentences but "\n" will fuck it up. So how do i go into the next line and not have this "\n" screwing up my program ??! How do i go into the new line ?

  • Weakly connected balanced digraph

    - by user1074557
    How can I prove that if a balanced digraph is weakly connected, then it is also strongly connected? (balanced digraph means that for every node, it's indegree and outdegree is the same and weakly connected means the non-directed version of this graph is connected). What I can think of so far is: if the graph is balanced, it means it is a union of directed cycles. So if I remove any cycle, it will stay balanced. Also each vertex in the cycle has one edge coming into it and one edge leading out of it.. Then I guess I need to use some contradiction or induction to prove that the graph is strongly connected.. That's where I confused.

  • Does jquery require timestamp on GET Calls in IE7?

    - by Mithun P
    Please see the jQuery code below, it used to paginate some search results paginate: function() { $("#wishlistPage .results").html("<div id='snakeSpinner'><img src='"+BASE_URL+"images/snake.gif' title='Loading' alt='...'/></div>"); var url = BASE_URL+"wishlist/wishlist_paginated/"; $.ajax({ type: "GET", url: url, data: { sort_by:$('#componentSortOrder input:hidden').val(), offset:My.WishList.offset, per_page: 10, timestamp: new Date().getTime() }, success: function(transport){ $("#wishlistPage .results").html(transport); } }); }, My issue is not with the pagination, issue is when i need to call this same function when something happed to other part of the page which remove some search results, it brings the old results in IE7, other browsers works fine. So added the timestamp: new Date().getTime() part. That fixed the IE issue. I want o know why this happens in jQuery? Do I need to include a timestamp parameter to URL to avoid caching in all jQuery Ajax calls?

  • OpenGL ES perspective projection

    - by TimeManx
    I'm having a hard time understanding how glFrustum & gluPerspective work. I understand the concept of perspective projection but the functions aren't behaving how I expect them to. For example, if I set the frustum this way glFrustumf(0, 10, 0, 10, 1, 100) and have a rectangle at points 0, 0, 1, 0, 10, 1, 10, 10, 1, 10, 0, 1 then the rectangle is drawn with its left edge at -5 & right edge at 5, so the left half of the rectangle isn't visible. And if x is translated, I'd expect y to be too. But that doesn't happen either. In whatever examples I've seen, the coordinates for the projection matrix are taken as glFrustumf(-10, 10, -10, 10, 1, 100) but either way, whatever part is shown should be dependent on the rectangle's coordinates, right?

  • Make graphics on left and right side of text change width depending on the amount of text?

    - by Dustin McGrew
    I need to have an H1 tag centered between two graphics on the left and right of the text. The H1 text will be various widths depending on what page you are on. The dot on the left should stay on the left edge of the site and the line should extend until it reaches the edge of the text. Same for the right side. Is there a way to accomplish this by using CSS or even some jquery/javascript? In the attached graphic, if the text was just "WHO YOU ARE" I'd need the bars on the left and right to grow wider to bump up against the edges of the text.
