• Simulating water droplets on a window

  - by skyuzo

  How do I simulate water droplets realistically falling, gathering, and flowing down a window? For example, see http://www.youtube.com/watch?v=4jaGyv0KRPw. In particular, I want to simulate how smaller droplets merge together to form larger droplets that have enough weight to oppose the surface tension and flow downward, leaving a trail of water. I'm aware of fluid simulation, but how would it be applied in this situation?

• C++ OpenGL trouble trapping cursor in window

  - by ezio160324

  I am using OpenGL and I try to trap my cursor inside my game window (using both SetCursorPos and ClipCursor) But, these conflict with my camera rotation code as my camera is rotated with my mouse. If there is a way to do it, please let me know. If possible, I would be willing to make it so that when the cursor reaches an edge of the screen, it jumps to the opposite edge (though I fear that would also conflict with my camera code).

• view switcher in window

  - by RhZ

  I used to have button in my file viewer window that allowed me to easily change from list to compact to icons, which was really convenient. Now, in 12.04 (running gnome fallback mode to mostly keep my original layout) I don't have that anymore, I have to go to 'view' and then at the bottom of the menu choose the way I want to display the files. Any way to get this switcher back? In its place I just have a search function and buttons that I don't need and never use.

• How to install SQL Server 2005 Configuration Manager without installing SQL Server Management Studio

  - by Arnold Zokas

  Hi, I need to configure SQL Server aliases on a public-facing production server. To do that, I need to install SQL Server Configuration Manager. I was not able to find a standalone installer for that, so I am having to install SQL Server 2005 Client Components. This approach is not ideal as we don't want to have SSMS on an public-facing production server. Is there a way to install SQL Server 2005 Configuration Manager without installing SQL Server Management Studio? Thanks, Arnold

• Emacs and windows manager keyboard shortcuts without Win key

  - by Little Bobby Tables

  I found a classic M-Series keyboard and I want to use it. However, it does not have the "Windows" key (a.k.a "Super"), only the Shift, Control and Alt modifiers. My keyboard shortcuts are cluttered as-is, since that I try to control both Emacs and the windows manager (Gnome) only from the keyboard. I rely on the "Super" key to identify the windows manager shortcuts. What it the best practice for keyboard-centric work without the "Super" key?

• HTC Sync Manager and MKV files

  - by Zundrium

  My problem is pretty straight forward: HTC Sync manager works perfectly with my HTC One X. However, it filters extensions it's not able to use with it's stock applications. (HTC Sense) But 3rd party applications can handle other extensions of course. Is there a way to adjust the HTC Sync Manager so that extensions will not be filtered? And if that's not possible is there a syncronisation tool that synchronises automatically once the android device is connected through USB? (Tried Allway Sync, doesn't work properly)

• Ubuntu odd mouse and keyboard behavior when window gains inner focus

  - by Scott

  This morning on my Ubuntu 10.10 system when I open a window - for example, system-preferences-about me, if I click in to a field such as "work email", I can no longer close the window with the mouse! Clicking the X on the window will not work. Also, I loose the ability to click on anything else - clicking on the desktop, icons, menus, workspaces, etc. do not work. Even the effect when you hover over a folder on the desktop and that folder highlights - that stops until the window is closed. If I open this same screen but do not click in to a field, everything is fine - I can close the window with the X and everything else works fine. Same thing happens with several other windows I tried. Even calculator - I can open it, everything is fine until I click on a button in the calculator - then no ability to click on anything else. Have to Alt-F4 to close the window. The system is only about a week old from a fresh install (64 bit ubuntu - quad core amd machine). I uninstalled wine, turned off remote desktop/disabled in startup, also in startup disabled visual assistance, bluetooth, dropbox, klipper. Reboot, no difference. The only other thing non-standard I see in startup is nvidia. Using a logitec usb mouse, saitek usb keyboard. Was working fine yesterday. I can not think of anything I did / installed yesterday. I switched themse, then went to update manager and saw two x server / x org related updates and installed them, reboot and NOW IT IS FINE! However, then I re-enabled dropbox, klipper and remote desktop rebooted and the problem is back. Again I disabled and rebooted. Problem is still there!! So somehow I fixed it at least for a few minutes, but now it is back and I am out of ideas.

• Vista: window focus problem

  - by GateKiller

  Sorry for the vague title but this one is hard to explain so bear with me please. I'm using Windows Vista at work for web development and sometimes when I Click or Alt-Tab to background window, the window will get focus but it will not be brought to the front. In order to bring the window to the front, I have to click on the applications border (when the resize cursor appears) and the window will then jump to the front. I've had this problem for about a year now and it happens at least a dozen times a day, but it doesn't do this all the time - seems random. I hope I have explained the issue fully (and you've understood it) and would appreciate any constructive answers or comments to solve this problem. Example: If I Alt-Tab from Google Chrome to Notepad and this problem randomly occurs, Google Chrome will remain in front of Notepad, however, I will be able to type text into Notepad while the window is behind Google Chrome. Clicking on Notepad's content area will not bring it to the front but clicking it's window border will. Video Exampe http://vimeo.com/19388998 In this video, I clicked from Google Chome to UltraEdit and chrome stayed in font, but as you can see, I can still type in UltraEdit. I'm starting to believe that this could be a bug in Google Chrome so I'll continue to watch if this between other applications.

• Using JQuery to open a popup window and print

  - by TJ Kirchner

  Hello, A while back I created a lightbox plugin using jQuery that would load a url specified in a link into a lightbox. The code is really simple: $('.readmore').each(function(i){ $(this).popup(); }); and the link would look like this: <a class='readmore' href='view-details.php?Id=11'>TJ Kirchner</a> The plugin could also accept arguments for width, height, a different url, and more data to pass through. The problem I'm facing right now is printing the lightbox. I set it up so that the lightbox has a print button at the top of the box. That link would open up a new window and print that window. This is all being controlled by the lightbox plugin. Here's what that code looks like: $('.printBtn').bind('click',function() { var url = options.url + ( ( options.url.indexOf('?') < 0 && options.data != "" ) ? '?' : '&' ) + options.data; var thePopup = window.open( url, "Member Listing", "menubar=0,location=0,height=700,width=700" ); thePopup.print(); }); The problem is the script doesn't seem to be waiting until the window loads. It wants to print the moment the window appears. As a result, if I click "cancel" to the print dialog box, it'll popup again and again until the window loads. The first time I tried printing I got a blank page. That might be because the window didn't finish load. I need to find a way to alter the previous code block to wait until the window loads and then print. I feel like there should be an easy way to do this, but I haven't found it yet. Either that, or I need to find a better way to open a popup window and print from the lightbox script in the parent window, without alternating the webpage code in the popup window.

• Safely remove window subclassing?

  - by Vegard Larsen

  I am trying to subclass the currently focused window on a Windows system using a global CBT hook. This is related to what happens in this question, but the bug is different. What happens when this subclassing is in effect, is that Opera's (version 10.50) main window is prevented from displaying. Opera has a "splash screen" where you are required to click "Start" for the main window to show that appears after Opera has not shut down properly. Whenever this window pops up, Opera's main window won't show. If Opera was shut down properly, and this splash screen does not show, the main window displays as it should. HHOOK hHook; HWND hWndSubclass = 0; void SubclassWindow(HWND hWnd) { Unsubclass(); FARPROC lpfnOldWndProc = (FARPROC)SetWindowLongPtr(hWnd, GWLP_WNDPROC, (LPARAM)SubClassFunc); SetProp(hWnd, L"PROP_OLDWNDPROC", lpfnOldWndProc); hWndSubclass = hWnd; } void Unsubclass() { if (hWndSubclass != 0 && IsWindow(hWndSubclass)) { FARPROC lpfnOldWndProc = (FARPROC)GetProp(hWndSubclass, L"PROP_OLDWNDPROC"); RemoveProp(hWndSubclass, L"PROP_OLDWNDPROC"); SetWindowLongPtr(hWndSubclass, GWLP_WNDPROC, (LPARAM)lpfnOldWndProc); hWndSubclass = 0; } } static LRESULT CALLBACK SubClassFunc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { if (message == WM_MOVING) { // do something irrelevant } else if (message == WM_DESTROY) { Unsubclass(); } FARPROC lpfnOldWndProc = (FARPROC)GetProp(hWndSubclass, L"PROP_OLDWNDPROC"); return CallWindowProc((WNDPROC)lpfnOldWndProc, hWndSubclass, message, wParam, lParam); } static LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam) { if (nCode == HCBT_SETFOCUS && hWndServer != NULL) { SubclassWindow((HWND)wParam); } if (nCode < 0) { return CallNextHookEx(hHook, nCode, wParam, lParam); } return 0; } BOOL APIENTRY DllMain( HINSTANCE hInstance, DWORD Reason, LPVOID Reserved ) { switch(Reason) { case DLL_PROCESS_ATTACH: hInst = hInstance; return TRUE; case DLL_PROCESS_DETACH: Unsubclass(); return TRUE; } return TRUE; } My suspicion is that Opera's main window is somehow already subclassed. I imagine the following is happening: The window is created with it's own basic WndProc, and is given focus My application subclasses the window, storing the original WndProc Opera subclasses its own window When the window loses focus, I restore the original WndProc, thus ignoring the second WndProc Can this really be the case? Are there any other explanations?

• Maintain aspect ratio on browser window resize?

  - by Anthony

  I have a simple page with images, and when the user clicks the image, it opens up a new browser window with the image filling the area. I have the css set on the new window so that the image height and width are both 100% (and overflow is set to hidden) so that the window can be resized. But what I need is for the window to maintain aspect ratio if the user resizes it. Right now, I'm stuck because I'm not getting how the event works, but I think I'm making this harder than it needs to be. Right now I have: $(function(){ $(window).resize(function() { var height = $(this).attr("innerHeight"); var width = $(this).attr("innerWidth"); if(height/width != .75){ window.resizeTo(width,width*.75); } }); }); Before I added the conditional, the window would immediately start shrinking (apparently opening a new window fires the resize event). Adding the conditional preventing this from happening when the window opens, but any resizing starts the shrinking again. Is it just because the height and width are never exactly the right ratio (should I manually set the width to a round number ever time) or is there something else I'm doing wrong? Or is there some other way to get what I'm after that's more straightforward?

• How to make ad-hoc network connection?

  - by Johan Nathaniel Soedjono

  I can't make ad-hoc from my netbook (Ubuntu 12.04). It has internet source from ethernet. I have tried making from network manager. But it always says 'Wireless Network Disconnected' and can't be detected by neither my other laptop nor my cell phone which have wifi. How can I make adhoc from it? I have already tried making a connection in Network Manager a lot of times, but it still can't connect and appear notification 'Wireless Network Disconnected'.

• Windows in StreamInsight: Hopping vs. Snapshot

  - by Roman Schindlauer

  Three weeks ago, we explained the basic concept of windows in StreamInsight: defining sets of events that serve as arguments for set-based operations, like aggregations. Today, we want to discuss the so-called Hopping Windows and compare them with Snapshot Windows. We will compare these two, because they can serve similar purposes with different behaviors; we will discuss the remaining window type, Count Windows, another time. Hopping (and its syntactic-sugar-sister Tumbling) windows are probably the most straightforward windowing concept in StreamInsight. A hopping window is defined by its length, and the offset from one window to the next. They are aligned with some absolute point on the timeline (which can also be given as a parameter to the window) and create sets of events. The diagram below shows an example of a hopping window with length of 1h and hop size (the offset) of 15 minutes, hence creating overlapping windows:   Two aspects in this diagram are important: Since this window is overlapping, an event can fall into more than one windows. If an (interval) event spans a window boundary, its lifetime will be clipped to the window, before it is passed to the set-based operation. That’s the default and currently only available window input policy. (This should only concern you if you are using a time-sensitive user-defined aggregate or operator.) The set-based operation will be applied to each of these sets, yielding a result. This result is: A single scalar value in case of built-in or user-defined aggregates. A subset of the input payloads, in case of the TopK operator. Arbitrary events, when using a user-defined operator. The timestamps of the result are almost always the ones of the windows. Only the user-defined  operator can create new events with timestamps. (However, even these event lifetimes are subject to the window’s output policy, which is currently always to clip to the window end.) Let’s assume we were calculating the sum over some payload field: var result = from window in source.HoppingWindow( TimeSpan.FromHours(1), TimeSpan.FromMinutes(15), HoppingWindowOutputPolicy.ClipToWindowEnd) select new { avg = window.Avg(e => e.Value) }; Now each window is reflected by one result event:   As you can see, the window definition defines the output frequency. No matter how many or few events we got from the input, this hopping window will produce one result every 15 minutes – except for those windows that do not contain any events at all, because StreamInsight window operations are empty-preserving (more about that another time). The “forced” output for every window can become a performance issue if you have a real-time query with many events in a wide group & apply – let me explain: imagine you have a lot of events that you group by and then aggregate within each group – classical streaming pattern. The hopping window produces a result in each group at exactly the same point in time for all groups, since the window boundaries are aligned with the timeline, not with the event timestamps. This means that the query output will become very bursty, delivering the results of all the groups at the same point in time. This becomes especially obvious if the events are long-lasting, spanning multiple windows each, so that the produced result events do not change their value very often. In such a case, a snapshot window can remedy. Snapshot windows are more difficult to explain than hopping windows: they represent those periods in time, when no event changes occur. In other words, if you mark all event start and and times on your timeline, then you are looking at all snapshot window boundaries:   If your events are never overlapping, the snapshot window will not make much sense. It is commonly used together with timestamp modification, which make it a very powerful tool. Or as Allan Mitchell expressed in in a recent tweet: “I used to look at SnapshotWindow() with disdain. Now she is my mistress, the one I turn to in times of trouble and need”. Let’s look at a simple example: I want to compute the average of some value in my events over the last minute. I don’t want this output be produced at fixed intervals, but at soon as it changes (that’s the true event-driven spirit!). The snapshot window will include all currently active event at each point in time, hence we need to extend our original events’ lifetimes into the future: Applying the Snapshot window on these events, it will appear to be “looking back into the past”: If you look at the result produced in this diagram, you can easily prove that, at each point in time, the current event value represents the average of all original input event within the last minute. Here is the LINQ representation of that query, applying the lifetime extension before the snapshot window: var result = from window in source .AlterEventDuration(e => TimeSpan.FromMinutes(1)) .SnapshotWindow(SnapshotWindowOutputPolicy.Clip) select new { avg = window.Avg(e => e.Value) }; With more complex modifications of the event lifetimes you can achieve many more query patterns. For instance “running totals” by keeping the event start times, but snapping their end times to some fixed time, like the end of the day. Each snapshot then “sees” all events that have happened in the respective time period so far. Regards, The StreamInsight Team

• Emacs 23.2 opens a new window for each compile error/warning navigated to

  - by Grant Limberg

  I've recently upgraded from Carbon Emacs (v22.3) to vanilla Emacs 23.2 (from http://www.emacsformacosx.com). On Carbon Emacs when compiling a project, The frame is split in two with the current source file/SConscript in the top window, and the compile output in the bottom window. I'd hit C-x ` to navigate to the first warning or error in the compile output and it would replace whatever was in the top window with the source file the error or warning is in. In Emacs 23.2, however, a 3rd window is opened causing two windows open in the top half of the frame (split vertically) and the compile output in the window of the bottom half of the frame. How do I tell Emacs to not open a new window and instead open the code in the the existing non-compiler output window in the frame? A little further clarification on the behavior that I just noticed. If I hit C-x ` while the buffer containing the source file or SConscript file is active, no new window is opened. It's only if I'm manually navigating through the *compilation* buffer and hitting enter on an error or warning, or mouse clicking on a warning when a third buffer window appears.

• Program To Cascade/Tile Windows

  - by Richard

  I have perhaps ten or fifteen windows open. I'd like a program which automatically resizes all the windows and arranges them in columns and rows across the screen (a grid formation), automatically figuring out the largest size for the windows so that they still fit. This isn't an "Expose" type program - I want the windows to stay resized. I am using OpenBox to do my window management and am otherwise happy with it, I don't want to find a whole new window manager just to solve this problem. The program Tile is almost perfect, but it doesn't know how to lay the windows out in a grid formation. Any thoughts? Thanks!

• Upgrade to Quantal unity top bar, side bar, and window declorations missing

  - by Nicky Bailuc

  I upgraded from 12.04.1 to 12.10 via the Update Manager and the upgrade said it completed successfuly. However after rebooting the unity task bar was missing along with the launch bar and the window declorations. All compiz settings seemed to be purge deleted, and at first bootup it gave me a system error. The desktop exists, and once I remember I messed up the compiz settings and just had to press Ctrl+Alt+F1 and in the virtual terminal type "unity --reset" then "sudo reboot". Everything worked as if i reinstalled the entire operating system. This time it said “Warning no variable set. setting to :0. The reset option is now dupricated”. What am I suppose to do now? I need this fixed as soon as possible because I need a couple of certainly installed programs and the data within them (long story short).

• Mouse not clicking properly

  - by RamoneDexter

  Okay guys, here's a tricky one. I'm running 10.10 on my pc but i've had this issue for some time now.I'm having strange issues with the mouse. What happens is when I get into Ubuntu, I can click anything, but as soon as I click something to open a window, run a program, I can no longer click anything EXCEPT the last thing I clicked. When I right click the last thing I clicked, it allows me to click everything normally, but only until I open something new. So for example I'll click the email icon on docky to open up my email client, which opens but is unresponsive until I right click docky. Then if I open an attatchment, I must also right click the MENU bar on my email client. Sometimes it also works if I simply right click on the newly opened window. I have tried this mith mutiple mice and still the same issue.
