• "Exclusive" DirectDraw palette isn't actually exclusive

  - by CyberShadow

  We're maintaining an old video game that uses a full-screen 256-color graphics mode with DirectDraw. The problem is, some applications running in the background sometimes try to change the system palette while the game is running, which results in corrupted graphics. We can (sometimes) detect when this happens by processing the WM_PALETTECHANGED message. A few update versions ago we added logging (just log the window title/class/process name), which helped users identify offending applications and close them. MSN Live Messenger was a common culprit. The problem got worse when we found out that Windows Vista (and 7) does it "by itself". The WM_PALETTECHANGED parameters point towards CSRSS and the desktop window. In Vista, a workaround that often worked was to open any folder (Computer, Documents, etc.) and leave it open while running the game. Sounds ridiculous, but it worked - in most cases. In Windows 7, not even this workaround worked any more. Users found that stopping some services (Windows Update and the indexing service) also resolved the problem on some configurations. Some time ago I just started trying random things in hope of finding a solution. I found that setting the GDI palette (using Create/SelectPalette) before setting the DirectDraw palette (using IDirectDrawPalette::SetEntries) would restore the palette after it became corrupted (WM_PALETTECHANGED handler). SetSystemPaletteUse and calling SetPalette on the primary surface helped some more. However, there is still perceivable flickering when an application tries to steal the palette, which is especially prominent during fades. Question: is there a way to get a "real" exclusive palette, which completely disallows other applications changing the Windows palette as long as our game retains focus?

• Best way to display a "High Scores" Results

  - by George

  First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app! Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score. Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML? Or an even better question, is there a better way? Thanks in advance for any and all help! Geo...

• SIGABRT on any UIView touch

  - by bitcruncher

  Hi. I'm afraid no amount of Googling has been able to save my hyde on this. I seem to be getting SIGABRT error anytime I touch the screen of the phone, on any UIView. The debugger console posts this error before the SIGABRT: .... [310:207] *** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0 .... [310:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0' (this is not my specific call to _exclusiveTouchView, of course.) I would gladly post some code, but the truth is I cannot find (or guess) where this problem may be coming from. This is not happening on any ONE UIView but on all the UIViews in my stack. I can summarize the display logic, though, perhaps that will shed some light. So the application is created and a UIWindow is alloc'd. A single viewcontroller is then alloc'd, which makes and adds its own blank self.view, to which the other UIViews, representing the different game states, are attached. Interestingly enough, this error is does NOT happen on the Simulator, but happens consistently on the device. And I should also mention that the application has yet to override/use any of the touchesBegan:/Ended:/Moved: etc... In other words, this error happens without these methods in the code. I'm really not understanding where this error is coming from... Any suggestions?

• cocoa hello world screensaver

  - by RW

  I have been studying NSView and as such I thought I would give a shot at a screen saver. I have been able to display and image in an NSView but I can't seen to modify this example code to display a simple picture in ScreenSaverView. http://www.mactech.com/articles/mactech/Vol.20/20.06/ScreenSaversInCocoa/ BTW great tutorial that works with Snow Leopard. I would think to simply display an image I would need something that looked like this... What am I doing wrong? // // try_screensaverView.m // try screensaver // #import "try_screensaverView.h" @implementation try_screensaverView - (id)initWithFrame:(NSRect)frame isPreview:(BOOL)isPreview { self = [super initWithFrame:frame isPreview:isPreview]; if (self) { [self setAnimationTimeInterval:1]; //refresh once per sec } return self; } - (void)startAnimation { [super startAnimation]; NSString *path = [[NSBundle mainBundle] pathForResource:@"leaf" ofType:@"JPG" inDirectory:@""]; image = [[NSImage alloc] initWithContentsOfFile:path]; } - (void)stopAnimation { [super stopAnimation]; } - (void)drawRect:(NSRect)rect { [super drawRect:rect]; } - (void)animateOneFrame { ////////////////////////////////////////////////////////// //load image and display This does not scale the image NSRect bounds = [self bounds]; NSSize newSize; newSize.width = bounds.size.width; newSize.height = bounds.size.height; [image setSize:newSize]; NSRect imageRect; imageRect.origin = NSZeroPoint; imageRect.size = [image size]; NSRect drawingRect = imageRect; [image drawInRect:drawingRect fromRect:imageRect operation:NSCompositeSourceOver fraction:1]; } - (BOOL)hasConfigureSheet { return NO; } - (NSWindow*)configureSheet { return nil; } @end

• Need to call original function from detoured function

  - by peachykeen

  I'm using Detours to hook into an executable's message function, but I need to run my own code and then call the original code. From what I've seen in the Detours docs, it definitely sounds like that should happen automatically. The original function prints a message to the screen, but as soon as I attach a detour it starts running my code and stops printing. The original function code is roughly: void CGuiObject::AppendMsgToBuffer(classA, unsigned long, unsigned long, int, classB); My function is: void CGuiObject_AppendMsgToBuffer( [same params, with names] ); I know the memory position the original function resides in, so using: DWORD OrigPos = 0x0040592C; DetourAttach( (void*)OrigPos, CGuiObject_AppendMsgToBuffer); gets me into the function. This code works almost perfectly: my function is called with the proper parameters. However, execution leaves my function and the original code is not called. I've tried jmping back in, but that crashes the program (I'm assuming the code Detours moved to fit the hook is responsible for the crash). Edit: I've managed to fix the first issue, with no returning to program execution. By calling the OrigPos value as a function, I'm able to go to the "trampoline" function and from there on to the original code. However, somewhere along the lines the registers are changing and that is causing the program to crash with a segfault as soon as I get back into the original code.

• How to add video into a webpage for mobile web browsers.

  - by payling

  Our company is making a mobile version of our website. We have several product videos we want to show on the mobile version. When I try to use <a href="video.wmv">video</a> I get sound playing but a black screen on my htc incredible android os phone. I'm thinking that the video is playing but in a different browser window. I need it to display all in one window without having to switch to a different window. I tried the html embed tags and get no video or sound at all, from what I've read these tags are not very realiable cross browser. I also just tried the html5 video tags below. I get an icon identifying that it's a video file but it doesn't play. <video src="video.wmv" controls="controls"> your browser does not support the video tag </video> Is there a special format the video file needs to be in? Should I be using the href or embed tags, what other options do I have? If it helps to know, I'm using the mobile doctype on my webpages. Thanks

• How much should the AppDelegate do?

  - by Rudiger

  I'm designing quite a large App and on startup it will create sessions with a few different servers. As they are creating a session which is used across all parts of the app its something I thought would be best in App Delegate. But the problem is I need the session progress to be represented on the screen. I plan to have a UIToolBar at the bottom of the main menu which I don't want to cover with the progress bar but cover the UIView above it.So the way I see it I could do it a few different ways. 1) Have the App Delegate establish the sessions and report the progress to the main menu class so it can represent it in the progress bar (will I have any issues doing this if the sessions are created in a separate thread?), 2) have the App delegate display the main menu (UIView with a bunch of buttons and UIToolBar) and have it track and display the progress (I have never displayed anything in the App Delegate but assume you can do this but its not recommended) or 3) have the App Delegate just push the main menu and have the mainMenu class create the sessions and display the progress bar. 4) I think the other way to do it is to create the sessions in a delegate class and have the delegate set to mainMenu rather than self (AppDelegate), although I've never used anything other then self so not sure if this will work or if I will be able to close the thread (through calling super maybe?) as its running in the AppDelegate rather than the delegate of the class. As I've kinda said before the sessions are being created in a class in a separate thread so it wont lock the UI and I think the best way is the first but am I going to have issues having it running in a separate thread, reporting back to the app delegate and then sending that message to the mainMenu view? I hope that all makes sense, let me know if you need any further clarification. Any information is appreciated Cheers,

• Alternate widgets and logic for ManyToManyField with Django forms

  - by Jaearess

  In my Django project, I have a simple ticket system. When creating a ticket, certain users have the ability to assign the ticket to other users, and to email the ticket to other users as well (this is used as an FYI for those users, so they're aware of the ticket, even though it's not assigned to them.) At the moment, the form for adding a ticket is simply the default Django form, with the "assigned_to" and "email_to" fields being ManyToManyFields, and therefore displayed as MultipleSelect widgets, each with a list of all users. Due to the relatively large number of users, and general awkwardness of the MultipleSelect widget, and alternate layout is now required. The desired layout is a pair of simple Select widgets side-by-side. The first has the option of "Assign to" or "Email to" and the second is a list of the users. Essentially, like this: [Assign to] [John Doe] [Email to] [Jane Roe] [Jack Smith], etc. Of course, since an arbitrary number of users can be assigned or emailed a ticket, there's a simple button that runs some Javascript to add another set of widgets, to allow the user to assign and email as many people as they need to. So far all of that is fairly simple and straight forward. However, the problem I have is using this widget setup/logic setup with Django forms. Instead of lists of users to assign to and email, instead we're getting back pairs of information, one a user and the other which list that user should be placed in. What I'm looking for, but have yet to find, is a way to offload the translation between how the user uses the form, and how Django understands the model to the form itself, so I don't have to manually do the processing of the data before passing it to the form in each place this form is used. Additionally, there's a review screen with the option to go back and change the form before submitting it, so a way to have the form translate both to and from this format would be extremely helpful.

• How do I add and remove an event listener using a function with parameters?

  - by Bungle

  Sorry if this is a common question, but I couldn't find any answers that seemed pertinent through searching. If I attach an event listener like this: window.addEventListener('scroll', function() { check_pos(box); }, false); it doesn't seem to work to try to remove it later, like this: window.removeEventListener('scroll', function() { check_pos(box); }, false); I assume this is because the addEventListener and removeEventListener methods want a reference to the same function, while I've provided them with anonymous functions, which, while identical in code, are not literally the same. How can I change my code to get the call to removeEventListener to work? The "box" argument refers to the name of an <iframe> that I'm tracking on the screen; that is, I want to be able to subscribe to the scroll event once for each <iframe> that I have (the quantity varies), and once the check_pos() function measures a certain position, it will call another function and also remove the event listener to free up system resources. My hunch is that the solution will involve a closure and/or naming the anonymous function, but I'm not sure exactly what that looks like, and would appreciate a concrete example. Hope that makes sense. Thanks for any help!

• Lookup site column not saving/storing metadata for Office 2007 documents?

  - by Greg Hurlman

  I'm having this issue on several server environments. We have a list at the site collection root. There is a site column created as a multi-value lookup on that list's Title field. This site column is used in document libraries in subsites as a required field. When we upload anything but an Office 2007 document, the user is presented with the document metadata fill-in screen (EditForm.aspx?Mode=Upload), the user fills in the appropriate data (including picking a value(s) for this lookup), and clicks "check in" - the document is checked in as expected, with the lookup field's value filled in. With an Office 2007 document, this fails. The user selected values for the lookup field do not ever make it to the server - no errors are thrown, but the field is not saved with the document. We have an event listener on these document libraries, and if we inspect the incoming SPListItem on the event listener method before a single line of our code has run, we see that the value for the lookup field is null. It smells like a SharePoint bug to me - but before I go calling Microsoft, has anyone seen this & worked around it? Edit: the only entry I see in the SP trace logs relating to the problem: CMS/Publishing/8ztg/Medium/Got List Item Version, but item was null

• Registry remotley hacked win 7 need help tracking the perp

  - by user577229

  I was writing some .VBS code at thhe office that would allow certain file extensions to be downloaded without a warning dialog on a w7x32 system. The system I was writing this on is in a lab on a segmented subnet. All web access is via a proxy server. The only means of accessing my machine is via the internet or from within the labs MSFT AD domain. While writing and testing my code I found a message of sorts. Upon refresing the registry to verify my code changed a dword, instead the message HELLO was written and visible in regedit where the dword value wass called for. I took a screen shot and proceeded to edit my code. This same weird behavior occurred last time I was writing registry code except on another internal server. I understand that remote registry access exists for windows systems. I will block this immediately once I return to the office. What I want to know is, can I trace who made this connection? How would I do this? I suspect the cause of this is the cause of other "odd" behaviors I'm experiencing at work such as losing control of my input director master control for over an hour and unchanged code that all of a sudden fails for no logical region. These failures occur at funny times, whenver I'm about to give a demonstration of my test code. I know this sounds crazy however knowledge of the registry component makes this believable. Once the registry can be accessed, the entire system is compromised. Any help or sanity checking is appreciated.

• Modal dialog focus problems on WPF application

  - by Donal

  Hi, I have a problem with my wpf application where a modal dialog will appear behind the main application causing it to hang. It is very inconsistent, where most of the time the pop-up works correctly and is shown in front but occasionally it will pop-up behind, which stops any interaction with it. I can still close the dialog using the taskbar if this happens. I have noticed that it generally occurs when lots of other applications are open and the taskbar is full. Also, I am working with two screens and the problem only occurs on the screen with the taskbar - very wierd! The dialog is a window control, which contains an injected usercontrol as it's data context. To set the owner of the window before calling ShowDialog(), the first active window in the application is used instead of Window.GetWindow(this): private static Window GetOwner() { if (Application.Current != null) { var owner = Application.Current.Windows.Cast().FirstOrDefault(w = w.IsActive); return owner ?? Application.Current.MainWindow; } return null; } Any ideas of what may be causing this problem? or even how to try and track it so I can gather more information when it happens? Thanks, Donal

• Android application listed as compatible with Sony Xperia S but still filtered from google play

  - by mlidal

  I have published an Android application and some users are complaining that it is listed as not compatible with Sony Xperia S. According to the developer console Xperia S (LT26i) is listed as compatible. Do anyone know of any reason why the app is still filtered from google play? I have seen people reporting problems with big apk files. This app is about 20Mb in size, with the largest file being 14Mb. Quite a bit but not enough to cause problems I think...

• jquery: how can i load the Google Maps API via ajax?

  - by Haroldo

  Before you reply: this is not as straight foward as you'd expect! I have a 'show on map' button which when clicked opens a dialogbox/lightbox with the google map in. I don't want to load the maps api on pageload, just when a map has been requested This is php file the "show on map" button puts into the dialog box: <div id="map_canvas"></div> <script type="text/javascript"> $(function() { //google maps stuff var latlng = new google.maps.LatLng(<?php echo $coords ?>); var options = { zoom: 14, center: latlng, mapTypeControl: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById('map_canvas'), options); var marker = new google.maps.Marker({ position: new google.maps.LatLng(<?php echo $coords ?>), map: map }); }) </script> I've been trying to load the API before ajaxing in the dialog like this: $('img.map').click(function(){ var rel = $(this).attr('rel'); $.getScript('http://maps.google.com/maps/api/js?sensor=false', function(){ $.fn.colorbox({ href:rel }) }); }) this doesn't seem to work :( i've also tried: adding <script src="http://maps.google.com/maps/api/js?sensor=false"></script> to the ajax file type="text/javascript" running $.getScript('http://maps.google.com/maps/api/js?sensor=false'); on doc.ready the problem the browser seems to be redirected to the api.js file - you see a white screen

• Quartz 2D or OpenGL ES? Pros and cons in the long term, possibility of migration to other platforms.

  - by fspirit

  Hi all! I'm having a hard time deciding whether to go with Quartz2D or OpenGL for an iPad game. It will be 2D mostly, but effect-intense (simultaneous lighting effects for 10-30 objects, 10-20 simultaneous animations on the screen). So far, assuming i'm equally dumb in both technologies and have to learn them from the ground, i came to this list. (I've read several topics here, on SO, with names like "Quartz or OpenGL", but i'm still left with some questions) Quartz: Better time-to-market, because of ready to use absractions like UIView, UIImageView, CoreAnimation abstractions Open GL ES Closer to hardware, thus, performance is better. App, implemented with OpenGL ES can be easier migrated to Android, MeeGo, Windows Phone, etc. My questions are: How time will it take to rewrite Quartz 2d app to use OpenGL? Lets say it took me 2 man-month to write Quartz app, how much time will i need to rewrite it? (Please, just some subjective opinions, i'll try to summarize them somehow) Regarding the ease of migration to other platforms, when using OpenGL, is it really so? Or efforts when migrating Quartz app from iPhoneOS to Android will be not so much bigger, compared to OpenGL app migration? (Ease of migration is quite important criterion) Regarding OpenGL, should i go with OpenGL 1.1 or 2.0, concerning migration? (Android supports 2.0 through NDK, but dont know whether NDK's use will increase or decrease migration efforts)

• Fast Lightweight Image Comparisson Metric Algorithm

  - by gav

  Hi All, I am developing an application for the Android platform which contains 1000+ image filters that have been 'evolved'. When a user selects a photo I want to present the most relevant filters first. This 'relevance' should be dependent on previous use cases. I have already developed tools that register when a filtered image is saved; this combination of filter and image can be seen as the training data for my system. The issue is that the comparison must occur between selecting an image and the next screen coming up. From a UI point of view I need the whole process to take less that 4 seconds; select an image- obtain a metric to use for similarity - check against use cases - return 6 closest matches. I figure with 4 seconds I can use animations and progress dialogs to keep the user happy. Due to platform contraints I am fairly limited in the computational expense of the algorithm. I have implemented a technique adapted from various online tutorials for running C code on the G1 and hence this language is available Specific Constraints; Qualcomm® MSM7201A™, 528 MHz Processor 320 x 480 Pixel bitmap in 32 bit ARGB ~ 2 seconds computational time for the native method to get the metric ~ 2 seconds to compare the metric of the current image with training data This is an academic project so all ideas are welcome, anything you can think of or have heard about would be of interest to me. My ideas; I want to keep the complexity down (O(n*m)?) by using pixel data only rather than a neighbourhood function I was looking at using the Colour historgram/Greyscale histogram/Texture/Entropy of the image, combining them to make the measure. There will be an obvious loss of information but I need the resultant metric to be substantially smaller than the memory footprint of the image (~0.512 MB) As I said, any ideas to direct my research would be fantastic. Kind regards, Gavin

• [iPhone] UIScrollView notifications

  - by ryyst

  Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

• NSOperation for animation loop causes strange scrolling behaviour

  - by Tricky

  Hi, I've created an animation loop which I run as an operation in order to keep the rest of my interface responsive. Whilst almost there, there is still one remaining issue. My UIScrollViews don't seem to be reliably picking up when a user touch ends. What this means is, for example, if a user drags down on a scroll view, when they lift their fingers the scrollview doesn't bounce back into place and the scrollbar remains visible. As if the finger hasn't left the screen. It takes another tap on the scrollview for it to snap to its correct position and the scrollbar to fade away... Here's the loop I created in a subclassed NSOperation: (void)main { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; _displayLink = [[CADisplayLink displayLinkWithTarget: self selector: @selector(animationLoop:)] retain]; [_displayLink setFrameInterval: 1.0f]; [_displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode: NSRunLoopCommonModes]; while (![self isCancelled]) { NSAutoreleasePool *loopPool = [[NSAutoreleasePool alloc] init]; [runLoop runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; [loopPool drain]; } [_displayLink invalidate]; [pool release]; } DOes anyone have any idea what might be going on here, and even better how to fix it... Thanks!

• Question about making Asynchronous call in C# (WPF) to COM object

  - by Andrew

  Hi, Sorry to ask such a basic question but I seem to have a brain freeze on this one! I'm calling a COM (ATL) object from my WPF project. The COM method might take a long time to complete. I thought I'd try and call it asychronously. I have a few demo lines that show the problem. private void checkBox1_Checked(object sender, RoutedEventArgs e) { //DoSomeWork(); AsyncDoWork caller = new AsyncDoWork(DoSomeWork); IAsyncResult result = caller.BeginInvoke(null, null); } private delegate void AsyncDoWork(); private void DoSomeWork() { _Server.DoWork(); } The ATL method DoWork is very exciting. It is: STDMETHODIMP CSimpleObject::DoWork(void) { Sleep(5000); return S_OK; } I had expectations that running this way would result in the checkbox being checked right away (instead of in 5 seconds) and me being able to move the WPF gui around the screen. I can't - for 5 seconds. What am I doing wrong? I'm sure it's something pretty simple. Delegate signature wrong? Thanks.

• Rails does not display error messages on a form in a custom method

  - by slythic

  Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

• Changing the parameters of a Javascript function using GreaseMonkey

  There are a lot of questions here about Greasemonkey, but I didn't see anything directly related to my question. I'm on a website that uses a text editor control, and it's really annoying that they don't allow horizontal resizing (only vertical). So if you are using a cheapo projector that only supports 1024x768, the text runs off of the screen and there's nothing you can do about it. I looked at the page source, and found the section of code that I want Greasemonkey to modify: <script type="text/javascript"> // TinyMCE instance type: CD_TinyMCE tinyMCE.init({ convert_urls : "", mode : "specific_textareas", editor_selector : "rte", theme : "advanced", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", theme_advanced_resizing : true, **theme_advanced_resize_horizontal : false**, ... I just want to change the boldfaced value to true. I tried to approach this the brute force way and replace the text this way: function allowHorizontalResize() { var search_string = "theme_advanced_resize_horizontal : false"; var replace_string = "theme_advanced_resize_horizontal : true"; var doc_text = document.body.innerHTML; document.body.innerHTML = doc_text.replace( search_string, replace_string); } ...but it doesn't work. However, I know the basic search and replace part works because I can use this script to replace text within the editor -- I just can't change the javascript code that initializes the text editor. Can someone explain what I'm doing wrong? Is this even possible?

• Exclude specific value from a Min/Max agregate funcion using ICriteria.

  - by sparks

  I have a schedule (Voyages) table like this: ID Arrival Departure OrderIndex 1 01/01/1753 02/10/2009 0 1 02/11/2009 02/15/2009 1 1 02/16/2009 02/19/2009 2 1 02/21/2009 01/01/1753 3 2 01/01/1753 03/01/2009 0 2 03/04/2009 03/07/2009 1 2 03/09/2009 01/01/1753 2 By design i save '01/01/1753' as a default value if the user doesn't fill a the field on the capture screen and for the very first Arrival and the very last Departure which are never provided. Im using Nhibernate and Criteria, and im wondering whats the best way to query this data if i want to know the First departure and last arrival for each voyage in the table. My first thought was a groupby (ID) and then do some Min and Max with the arrival and departure but the `'01/01/1753' VALUE is messing aronud. ... .SetProjection(Projections.ProjectionList() .Add(Projections.GroupProperty("ID"), "ID") .Add(Projections.Min("DepartureDate"), "DepartureDate") .Add(Projections.Max("ArrivalDate"), "ArrivalDate") ) ... So is there a way to skip this value in the Min function comparison (without losing the whole row of data), or there is a better way to do this, maybe utilizing the OrderIndex that always indicate the correct order of the elements, maybe ordering ASC taking the 1st and then Order DESC and taking the 1 st again, but im not quite sure how to do that with criteria syntax.

• jQuery: Stop browser scrolling on event update beyond the fold?

  - by neezer

  I have several links at the bottom of my page that update content at the top of my page (more than a viewport away). Here's the gist of what the update looks like: $('#private-photo div').fadeOut(function() { $(this).html('<%= escape_javascript(image_tag current_user.private_photo.image.url(:profile)) %>'); }).fadeIn(); Basically it's just fading out the old content and fading in the new content. My problem is that when this happens, the browser window automatically scrolls up just far enough so that the bottom of the updated content (#private-photo div) appears at the top of the browser viewport. I do not want this to happen. I want the content to be updated (still fading in and out), but without the browser viewport realigning its focus. I want to keep the animation because if the user has a big enough screen, or if they are using a link closer to the top of the page, I still want them to see the animation. Any ideas about how to prevent the browser from scrolling as described? If not, any suggestions for workarounds? FYI, I have this same problem in Safari 4, Chrome (for Mac), & Firefox 3.5. EDIT: Here's the link that calls the update action, which is itself inside a Colorbox: $('a.edit-photo').colorbox({ title: function() { return 'Edit Photo in ' + $(this).attr('rel'); }, overlayClose: false, onComplete: function() { $('#edit-photo-modal').submit(function(e) { $('#photo_submit').after('<span id="saving">Saving...</span>'); e.preventDefault(); $.post($(this).attr('action'), $(this).serialize(), function() { $('#edit-photo-modal #saving').text('Saved!'); }, "script"); }); } }); The lightbox opens, presents a form fetched through an AJAX request, then (on submit) triggers the update action mentioned above. I had these links outside of the Colorbox in an earlier design revision, and they exhibited the same problem, so I've ruled out Colorbox itself as a cause. If you need anymore info, let me know!
