  • jQuery Columnizer plugin only working correctly on window resize.

    - by rcon
    Hi, I'm using the jQuery Columnizer plugin, and I'm running into a weird problem. Using 3 columns, I columnize content from a hidden div into a target div. It distributes only one paragraph to each of the first two columns and then puts all the remaining paragraphs into the last column. But the strange thing is that it auto-corrects itself when the window is resized. I'm guessing it has something to do with the target div resizing since opening a firebug console window also causes it to auto-correct itself. Setting lastNeverTallest:true doesn't seem to do anything. $('#hidden-about').columnize({ columns: 3, target: '#interiors', lastNeverTallest: true, doneFunc: function() { $('#interiors').css('white-space', 'normal'); $('#interiors').fadeIn(200); } Thanks for any suggestions!

  • How to customize Windows Failover clustering to trigger on failure of custom window service?

    - by melaos
    i'm a total newbie on windows failover clustering. and what i want to do now is to setup the FC (failover clustering) on two win 2008 R2 server. and right now i have my custom window service running on both machine. But they cannot run concurrently as it will mess up the DB, thus i just want one to be available at all time (high availability). so i'm wondering if there's any way to set the failover policy to include this custom window service that i've installed on these machines so that if this service goes down or die, then it will automatically trigger the failover to the second node. is this possible? or must it be done programatically? and if so what is the best way? thanks ~m

  • How to set a RichTextBox in Silverlight 4 to fit it's parent height and maintain it on resize?

    - by Ivan Zlatanov
    I am having hard times figuring this out. Here is what I need: <StackPanel x:Name="container" VerticalAlignment="Stretch"> <RichTextBox Height="???" /> </StackPanel> Basically what I know I can do is to bind RichTextBox Height to it's parent's height ( Height="{Binding ElementName=container, Path=ActualHeight}". Unfortunately this only works on load, because as it seems ActualHeight and ActualWidth don't notify for changes. So what is the best way in Silverlight 4 to tell RichTextBox or TextBlock, it doesn't matter, to fill it's parent height, and maintain scrollbar if it's content height is bigger. Is the only way to bind some Resize events and maintain the height explicitly? That seems really ugly to me?

  • Can a ScatterViewItem dynamically resize to fit its content?

    - by Brett
    We're hosting a control inside of a ScatterViewItem that dynamically changes its size at runtime as a result of having various sub-elements added, removed, and/or collapsed. We would like to have the hosting ScatterViewItem resize as well to properly fit its child controls, but we're having a hard time making this happen. We've tried a number of different things and the closest we've come is hooking into the child control's SizeChanged event and explicitly setting the ScatterViewItem's Width and Height, but this approach still has issues. When you define a ScatterViewItem and its content in XAML, the ScatterViewItem is sized appropriately. We would like to force the same behavior at runtime when its content changes size. Any help would be greatly appreciated. Thanks!

  • Multiple IP addresses to one NIC, but advanced IP settings window only shows one?

    - by tridium
    The ipconfig of my Windows Server 2003 server shows that the IP addresses 10.0.0.3, 10.0.0.11, and 10.0.0.12 are assigned to it. However, when I look in the Advanced TCP/IP Settings window for that connection, I only see the IP address of 10.0.0.3 listed there. In the Support tab for the connection, it shows that it's connected through 10.0.0.12, and in the Support Details window, it shows all the previously mentioned IP addresses. Where are these phantom IP addresses being stored and how can I free them up so I don't have any IP conflicts?

  • Is it possible for onunload confirm to open a new url in the same window?

    - by Dan Peschio
    Hi - this is my first post and I'm a JS novice, so please forgive my ignorance... Heres my question, its in two parts: 1.) At onunload I want an alert that asks the user if they would like to go to a related URL. The code I'm using works, but it open the URL in a new window and this can be blocked by a pop-up blocker even though the user has opted-in. Is there a way to have it open in the same window and negate the pop-up blocker? 2.) is there a way to take the onunload function out of the body tag and put it the script? Heres the code I'm using: <script language=javascript> function confirmit() { var closeit= confirm("Before you go would you like to add your press kit to the Search Press Kits database?"); if (closeit == true) {window.open("http://NEWURLHERE.com");} else {window.close();} } </script> </head> <body onunload="confirmit();"> peace </body> Thanks in advance, Dan

  • OS X crops the screenshot when capturing a single, maximised window.

    - by joshhunt
    Whenever I make a screen shot of just a single window that is maximised using the shortcut command + shift + 4 + space, it never accurately captures the full window. Instead, it just saves this: What is going on? Why has OS X started doing this? I have been using Snow Leopard for a while, so it is not like that is causing the problems directly. It is also not restricted to Safari. The same thing happens for iTunes, as well as others.

  • Difference between tcp recv buffer and tcp receive window size?

    - by pradeepchhetri
    The command shows the tcp receive buffer size in bytes. $ cat /proc/sys/net/ipv4/tcp_rmem 4096 87380 4001344 where the three values signifies the min, default and max values respectively. Then I tried to find the tcp window size using tcpdump command. $ sudo tcpdump -n -i eth0 'tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and port 80 and host google.com' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:15:41.465037 IP 172.16.31.141.51614 > 74.125.236.73.80: Flags [S], seq 3661804272, win 14600, options [mss 1460,sackOK,TS val 4452053 ecr 0,nop,wscale 6], length 0 I got the window size to be 14600 which is 10 times the size of MSS. Can anyone please tell me the relationship between the two.

  • How come this image won't resize to fit the sprite?

    - by George Edison
    I have this snippet of ActionScript code that is supposed to resize an image to fit the sprite: package { import flash.display.Sprite; import flash.display.Bitmap; import flash.events.Event; public class Main extends Sprite { [Embed(source = 'img.png')] private var TheImage:Class; public static const TheImageWidth:Number = 1300; public static const TheImageHeight:Number = 1300; public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point var image:Bitmap = new TheImage(); addChild(image); image.scaleX = width / TheImageWidth; image.scaleY = height / TheImageHeight; } } } Why isn't it working?

  • A hooked DirectX 9 program crashes on window resize, texture related.

    - by Ben
    I'm using EasyHook and SlimDX to overlay some graphics using SlimDX's Sprite and Texture classes. When I resize windows some programs fine, but others will crash - Winamp's MilkDrop 2 gives me an ambiguous memory error for example. I expect this is due to the after market Texture I created. The question is what VTable function should I hook and/or how/when do I dispose and recreate the Texture? Reset perhaps? If it isn't obvious I don't know much about DirectX.

  • Resize an asp.net panel width based on a checkboxlist?

    - by larryq
    Hi everyone, I have an asp.net panel that contains a checkboxlist. I'd like to resize it so that its width fits the list's contents snugly. Right now I'm handling the panel's pre rendering event, setting its width to match that of the checkboxlist. However it appears the checkboxlist's width property reads zero (at least in this pre render method) so the panel's width is set identically, which leads to inconsistent renderings in Firefox vs IE. Does anyone have a better approach to doing what I'm attempting here? Many thanks.

  • x11 looks ugly while opening a remote window from ssh. Can I use GTK themes?

    - by Simon
    I use to connect to a distant computer running linux from my mac using ssh. For example I use: $ ssh -Y login@host then $ gnome-open . in order to open a nautilus window. This window do open but it looks ugly. I found here that one can install GTK themes through Macports. I installed gtk2-aurora and gtk-chtheme and chose the aurora theme successfully, but my remote windows still look ugly. Is this theme (or others) working for remote windows or is it only for local x11 windows? Is there a way to improve the look and feel of remote windows?

  • How to safely transfer reference to object across window?

    - by Morgan Cheng
    I'm debugging a web application. Javasript in one window create one object and use it as argument to invoke global method in another window. Pseudo code is like below. var obj = new Foo(); anotherWin.bar(obj); In anotherWin, the argument is stored in global variable. var g_obj; function bar(obj) { g_obj = obj; ... } When other function tries to reference g_obj.Id, it throws exception "Cannot evaluate expression". This happens in IE8.0.7600.16385 on Windows 7. In Visual Studio debugger, when this exception happens, the g_obj shows as {...} It looks all its properties are lost. Perhaps the root reason is the object is created in one window but only referenced in another window. The object might be garbage-collected at any time. Is there any way to work around this?

  • Make JFace Window blink in taskbar or get users attention?

    - by Sophomore
    Hi folks I wonder someone has any idea how to solve this: In my Java Eclipse plugin there are some processes which take some time. Therefore the user might minimize the window and let the process run in the background. Now, when the process is finished, I can force the window to come to the top again, but that is a no-no in usability. I'd rather want the process to blink in the taskbar instead. Is there any way to achieve this? I had a look at the org.eclipse.jface.window but could'nt find anything like that, same goes for the SWT documentation... Another thing which came to my mind - as people are using this app on mac os x and linux as well, is there a platform independant solution, which will inform the user that the process has finished but without bringing the window to the top? Any ideas are highly welcome! Edit: I found out that on windows the user can adjust whether he would like to enable a force to foreground or not. If that option is disabled, the task will just blink in the taskbar... Here's a good read on that... If anyone maybe knows about some platform independant way of achieving this kind of behaviour, please share your knowledge with me!

  • How can I prevent the "... has stopped working" window on my Server 2008 R2 dev box?

    - by serialhobbyist
    I'm using a Windows Server 2008 x64 R2 machine as a development box. Amongst many other things I've got Visual Studio 2008 SP1 installed on it. When I'm working on a project, I sometimes need to use Debug Start without Debugging (Ctrl + F5). If the program throws an exception, I get a new R2-style window appear. I'm pretty sure I didn't see this on my XP box - this is the first time I've developed directly on a server. Is there any way to avoid this - it's really beginning to bug me? E.g. my current project is accessing a WCF service - I'm using Ctrl+F5 to start a console program client. I run it and get the window. The title is the name of the project I've just started and it contains: [insert-project-name-here] has stopped working Windows can check online for a solution to the problem. --> Check online for a solution and close the program --> Close the program --> Debug the program V View problem details. Clicking on "Close the program" will actually close the window and the exception message appears in the console, which is what I want (but without the extra window-faffing). How can I avoid this annoyance?

  • How do I maximize a window in one monitor and do other things on the other monitor

    - by RoboShop
    Hi, I have windows 7 installed on my laptop which is a Dell studio XPS 16. I recently set up a second monitor for it. I've noticed that when I load up "full maximisation" applications (I don't know the term) like a game or media center on one monitor, I can't seem to do anything with the other monitor. With the game, I can see the other monitor, I can play a movie on it even, but if I click the mouse button on it, it'll stop the game and alt-tab away. In Media Center, I can't even cross my mouse over the other monitor. So my question is, in Windows 7, is it possible to run programs like this that are designed to be run in one maximised window and still be able to do things on the other window?

  • Who's setting TCP window size down to 0, Indy or Windows?

    - by François
    We have an application server which have been observed sending headers with TCP window size 0 at times when the network had congestion (at a client's site). We would like to know if it is Indy or the underlying Windows layer that is responsible for adjusting the TCP window size down from the nominal 64K in adaptation to the available throughput. And we would be able to act upon it becoming 0 (nothing gets send, users wait = no good). So, any info, link, pointer to Indy code are welcome... Disclaimer: I'm not a network specialist. Please keep the answer understandable for the average me ;-) Note: it's Indy9/D2007 on Windows Server 2003 SP2. More gory details: The TCP zero window cases happen on the middle tier talking to the DB server. It happens at the same moments when end users complain of slowdowns in the client application (that's what triggered the network investigation). 2 major Network issues causing bottlenecks have been identified. The TCP zero window happened when there was network congestion, but may or may not be caused by it. We want to know when that happen and have a way to do something (logging at least) in our code. So where to hook (in Indy?) to know when that condition occurs?

  • How to use CSS to ensure items remain offscreen even if window is resized?

    - by Ashley Ward
    I am trying to implement a type of slider using jquery. However this question is about the CSS involved in trying to achieve the functionality. My site design occupies a central column of width 960px. Within this layout there is a central element, that I wish to slide right, on click of a "next" button, and at the same time, another element of the same class slides in from the left to occupy the space vacated. I have drawn a diagram of what I am trying to achieve. In this diagram the red blocks are the element I want to slide in and out, it is grouped by a div which moves left to produce the effect using jQuery I have 2 main questions: How do I get the correct margin values, given that the browser window width can vary and that all elements that are not the current item should be offscreen? 2.If the user were to resize the margins could be dynamically altered based on the values returned using the jQuery resize() event. Or is there a neater quicker better way of doing it using pure CSS?

  • How do I get a JComponent to resize after calling `setVisible(true)`?

    - by iWerner
    Our application displays a 2D view of our data (mainly maps) and then allows the user to change to a 3D view. The 2D and 3D views are generated by custom C++ code that is SWIG'ed into our Swing GUI and wrapped within a JComponent. These JComponents are then displayed within another parent JComponent. Our problem is that when we change from the 2D to the 3D view and then back to the 2D view, when we resize the window the 2D view does not get resized. The resize events don't get sent to the 2D view. Our application runs under Linux (Fedora 11). We're running Java version 1.6.0_12. Here is some sample code in which I've replaced the 2D view and 3D view with two 2 JButtons, that produces the same behaviour. Once you go to 3D and then back to 2D, resizing the window does not cause the 2D view to be resized. /* TestFrame.java * Compile with: $ javac TestFrame.java * Run with: $ java TestFrame */ import java.awt.BorderLayout; import java.awt.Container; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JButton; public class TestFrame extends javax.swing.JFrame { private boolean mode2D = true; private JButton view2D = null; private JButton view3D = null; private Container parent = null; public TestFrame() { initComponents(); containerPanel.setLayout(new BorderLayout()); view2D = new JButton("2D View"); view2D.addComponentListener(new MyListener("2D VIEW")); containerPanel.add(view2D); } private void changerButtonActionPerformed(java.awt.event.ActionEvent evt) { if (parent == null) { parent = view2D.getParent(); } if (mode2D) { System.out.println("Going from 2D to 3D"); view2D.setVisible(false); if (view3D != null) { view3D.setVisible(true); } else { view3D = new JButton("3D View"); view3D.addComponentListener(new MyListener("3D VIEW")); parent.add(view3D); } ((JButton) evt.getSource()).setText("Change to 2D"); mode2D = false; } else { System.out.println("Going from 3D to 2D"); view3D.setVisible(false); view2D.setVisible(true); ((JButton) evt.getSource()).setText("Change to 3D"); mode2D = true; } } public static void main(String args[]) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new TestFrame().setVisible(true); } }); } private javax.swing.JPanel containerPanel; private javax.swing.JButton changerButton; private class MyListener implements ComponentListener { private String name; public MyListener(String name) { this.name = name; } @Override public void componentHidden(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Hidden"); } @Override public void componentResized(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Resized"); } @Override public void componentShown(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Shown"); } @Override public void componentMoved(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Moved"); } }; @SuppressWarnings("unchecked") private void initComponents() { containerPanel = new javax.swing.JPanel(); changerButton = new javax.swing.JButton(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); containerPanel.setBorder(new javax.swing.border.MatteBorder(null)); javax.swing.GroupLayout containerPanelLayout = new javax.swing.GroupLayout(containerPanel); containerPanel.setLayout(containerPanelLayout); containerPanelLayout.setHorizontalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 374, Short.MAX_VALUE) ); containerPanelLayout.setVerticalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 239, Short.MAX_VALUE) ); changerButton.setText("Change to 3D"); changerButton.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { changerButtonActionPerformed(evt); } }); javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane()); getContentPane().setLayout(layout); layout.setHorizontalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addComponent(changerButton)) .addContainerGap()) ); layout.setVerticalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED) .addComponent(changerButton) .addContainerGap()) ); pack(); } } (My apologies for the Netbeans generated GUI code) I should mention that when we call parent.remove(view2D) and parent.add(view3D) to change the views the X Windows ID of our 3D view changes and we're unable to get our 3D view back. Therefore parent.remove(view2D) and parent.add(view3D) is not really a solution and we have to call setVisible(false) and setVisible(true) on the JComponents that contain our 2D and 3D views in order to hide and show them. Any help will be greatly appreciated.
