  • Change form field options dynamically (and restore previously selected options) using jQuery

    - by Martin
    I'm fairly new to both jQuery and JavaScript so can anyone please point out what I'm missing here? I have a form with multiple pairs of select fields, where the content of the second field relies on the selection of the first one. Once a value is chosen from the first one then a piece of jQuery code empties the corresponding second select options, gets new values as JSON and inserts them as new select values. All of this works with the code I've written. However if a user has chosen a second value, I'd like to restore it if possible (meaning if the new values also include the one previously selected). I tried to do this by first saving the second value and then trying to set it once the new options have been inserted. This did not work. However when trying to debug I inserted an alert() just before restoring the second value and with that in there it does work... Am I missing something very basic here? Any help would be appreciated. HTML: <select name="party-0-first" id="id_party-0-first"> <option value="" selected="selected">---------</option> <option value="1">first_value1</option> <option value="2">first_value2</option> <option value="3">first_value3</option> <option value="4">first_value4</option> </select> <select name="party-0-second" id="id_party-0-second"> <option value="" selected="selected">---------</option> <option value="1">second_value1</option> <option value="2">second_value2</option> <option value="3">second_value3</option> <option value="4">second_value4</option> </select> <select name="party-1-first" id="id_party-1-first"> ... JavaScript: $.fn.setSecond = function() { var divName = $(this).attr("name"); divName = divName.replace('-first', ''); divName = divName.replace('party-', ''); // Save the currently selected value of the "second" select box // This seems to work properly setValue = $('#id_party-' + divName + '-second').val(); // Get the new values $.getJSON("/json_opsys/", { client: $(this).val() }, function(data){ $('#id_party-' + divName + '-second').empty(); $('#id_party-' + divName + '-second').append('<option value="" selected="selected">---------</option>'); $.each(data, function(i, item){ $('#id_party-' + divName + '-second').append('<option value="' + item.pk + '">' + item.fields.name + '</option>'); }); }); // Here I try to restore the selected value // This does not work normally, however if I place a javascript alert() before // this for some reason it does work $('#id_party-' + divName + '-second').val(setValue); $(document).ready(function(){ $('[id*=first]').change(function() { $(this).setSecond(); }); });

  • Windows: Impact of clean install Service Pack 2 to applications & data?

    - by Thomas Matthews
    My Windows Vista Home Premium system is corrupt and won't install Service Pack 2. I have followed all the advice from Microsoft and still no luck. I would like to perform a clean install of Vista, then SP1, and then SP2. My concern is the effect of the clean install on the registry, my apps and all my data. My plan: 1. Download Vista Service Pack 1 (SP1) ISO and write to DVD. 2. Download Vista Service Pack 2 (SP2) ISO and write to DVD. 3. Backup all data, applications and registry to external hard drive (file copy not disk image) 4. ?? Format hard drive?? (is this necessary?) 5. Install Vista from DVDs / CDs. 6. Install SP1 from DVD 7. Install SP2 from DVD 8. Restore registry, applications and data from external hard drive. My questions: 1. Is formatting the hard drive a necessary step? 2. Will restoring the registry from the backup corrupt the system? 3. Should I use Windows Backup or ZIP/RAR? 4. Any gotcha's that I should look out for? Background: I am using Windows Vista Home Premium with SP1. The sfc program does not finish due to a resources problem (even when run as administrator). I have 5 users on it. After a while, the screen goes black and shows an error message window about an error with login.scr. Standard accounts display a black screen and can't run any applications. Administrative accounts have no problems (even standard accounts when converted to Administrative have no problem). The CBS log contains a lot of 0x8000ffff and E_UNEXPECTED errors (which Microsoft defines as catastrophic failure). This is the reasoning behind performing a clean install up to service pack 2.

  • SSAS 2008 backup/restore fails with a GetOverlappedResult 'Insufficient system resources exist to co

    - by Anant Aneja
    Hi, On my SSAS 2008 instance if a backup/restore of any database is made to/from a UNC path I get an error : The following system error occurred from a call to GetOverlappedResult for Physical file: '\server\share\OLAPDB.abf', Logical file: '' : Insufficient system resources exist to complete the requested service. . Server: The operation has been cancelled. (Microsoft.AnalysisServices) Creating/copying/moving a file on the share of any size on the share using explorer or the command prompt works. The most useful link I could find is : http://www.tech-archive.net/Archive/Development/microsoft.public.win32.programmer.kernel/2004-07/0475.html Can anyone shed more light on what could be causing this error ? (I've posted the same question on the SSAS forums - just a heads up)

  • Silverlight 4 RichTextBox - can't restore Xaml with text containing curly braces

    - by fuzzyman
    We have a Silverlight application using the RichTextBox as a rich text editor for the user to create emails. We actually have our own serializer but essentially we are saving and restoring the Xaml. As far as I can tell it is impossible to restore any text containing curly braces. You can demonstrate this fairly easily by creating a RichTextBox and typing something similar to "{weird}" into it. Then take the .Xaml property of the textbox and set it on the .Xaml property of another textbox - kablooie. As we have our own serializer I have tried escaping the Text member of the Run elements with "". This makes no difference. I've tried replacing the braces with &#123; but that doesn't work either.

  • Backup Active Directory only

    - by MainMa
    Hi, I have a server with Windows Server 2008. I want to install a new Windows Server 2008 R2 on a new hard disk but on a same machine. What is the way to backup/migrate only Active Directory? I found that migration must be done with Microsoft Active Directory Migration Tool, but it requires both source and target domains running at the same time. Any other suggests are to use an ordinary system backup/restore, but this will restore all other roles, whereas I need only Active Directory role on the new server.

  • firefox: getting access to the list of tabs/windows to restore on startup

    - by robb
    Sometimes ffox fails to restore the previously open tabs/windows. This might be happening when some of the urls to be opened are no longer reachable (e.g. behind a vpn) or after the underlying OS (Windows) has been forcibly restarted (e.g. to complete an automated patch installation). Anyway, after restarting, can this list of urls be recovered somehow? Say for example, I was daft enough to have clicked on "start new session". Can I still get access to the old list of open urls? There is the browser history of course, but it contains a lot of stuff - the urls that were open when ffox last exited are not obvious. It would be neat if they were marked in some way - tagged for example. .robb

  • C# and Linq: Generating SQL Backup/Restore From Code

    - by mdvaldosta
    I'm working with a C# and Linq to SQL Winforms app and needed to integrate backup and restores through the program. I used SMO and got it working pretty smoothly. The issue, however, is that the app is deployed using ClickOnce, which I like very much - but since I had to include the dll's the download size jumped from 3mb = 15mb. I know they've only got to download it once, but it also sucks for me as Visual Studio 2010 seems to upload the dll's every time and that takes a while on AT&T broadband (eh). So, anyone have any suggestion on how I can work out an effective backup/restore solution without using SMO objects?

  • Restoring using SyncBack without profiles

    - by Thomas Matthews
    I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

  • remove/restore elements, maintaining their events and element's children

    - by Emin
    I came to a situation where I need to edit the following in a way that, on some event (lets assume the 'click' event in this case) I need to remove (or unwrap?) the .container and the .header and have the .itemlist still visible/available on the page. And then, I need to restore .container and .header back again on some other event, while still maintain the event listeners on the a tags, and if possible, without removing the said items from the DOM. Is this possible? <ul class="container"> <li class="header"><a href="#">delete</a> | <a href="#">edit</a></li> <ul class="itemlist"> <li>some item</li> <li>some other item</li> </ul> </ul>

  • Restore history and current page on resuming webview

    - by qubit
    I have a webview that I use to navigate from page to page. I have implemented go back and go forward. My problem is that when I return to the webview after visiting another activity, the history is lost i.e. the webview starts again on the first page. How do I code it so that after I call finish on the webview to swap to another activity on returning to the webview, the WebBackForwardList is restored and I am taken to the page I was on when I left the webview? I have tried overriding onSaveInstanceState and onRestoreInstanceState using webview.save/restoreState(bundle) but with no success. I have achieved returning to the last page by saving the last url in preferences, but have been unable to restore the entire history.

  • script to dynamically fix ophaned users after db restore

    After performing a database restore, I want to run a dynamic script to fix ophaned users. My script below loops through all users that are displayed after executing sp_change_users_login 'report' and apply "alter user [username] with login = [username]" to fix SID conflicts verses static go statements.

  • Best way to fix an out-of-sync TFS workspace after a back-up/restore

    - by DanO
    Wednesday I had to restore from a back-up image I made on Monday. At the time of the snapshot I had about 20 files modified, which I later checked in, and more, on Tuesday. Now that I am back to a snapshot from Monday morning, my workspace has all of these files checked-out or added, etc. even my check-in comments and work-item associations. But I already did that check-in on Tuesday. I'm thinking I will shelve all the pending changes (just in-case), and then just undo all changes, and get latest (specific version). And I should be back to good. Any cautions or suggestions? (TFS 2008, VS2010)

  • Best way to manage the persistence of a form state, to and from a database

    - by Laurent.B
    In a JSP/Servlet webapp, I have to implement a functionality that allows a user to save or restore a form state, that latter containing for instance some search criteria. In other words, the user must be able to save or restore field values of a form, at any time. On the same page that contains that form, there's also another little form that allows him to name his form state before saving it. Then, later he'll be able to recall that state, via a combobox, and refill dynamically the form with the state he selected. I know how to implement that by hand but I would prefer not to reinvent the wheel then I'd like to know if there are some frameworks managing that kind of functionality ? A mix between JSP taglib, filter class, jQuery or other JavaScript frameworks... My research has not give anything yet. Thank you in advance.

  • Beginner: Restore previously serialized JFrame-object, how?

    - by elementz
    Hi all. I have managed to serialize my very basic GUI-object containing a JTextArea and a few buttons to a file 'test.ser'. Now, I would like to completely restore the previously saved state from 'test.ser', but seem to have a misconception of how to properly deserialize an objects state. The class MyFrame creates the JFrame and serializes it. Now I tried to deserialize like so: public class Deserialize { static Deserialize ds; MyFrame frame; public static void main(String[] args) { try { ds.deserialize(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void deserialize() throws ClassNotFoundException { try { ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.ser")); frame = (MyFrame) ois.readObject(); ois.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } Maybe somebody could point me into the direction where my misconception is? Thx in advance!

  • Dojo StackContainer children are not resizing on browser maximise/restore

    - by Andy
    Hi. I have the following nested layout in a dojo 1.4 app: BorderContainer 1 -- Stack Container 1 ----BorderContainer 2 ----BorderContainer 3 The StackContainer is sized with width and height 100%. When I resize the browser window using maximise/restore, the StackContainer correctly resizes to the center region of it's parent BorderContainer. The problem I have is that the StackContainer children (BorderContainer 2 and 3) do not get resized to the StackContainer's contentBox. Is there something special you have to do to force a resize of StackContainer children? I have tried calling StackContainer1.resize() but this makes no difference. Thanks in advance. Additional information: Thanks for the reply peller. The widget hierachy that contains the StackContainer is actually a custom widget, so the StackContainer is not actually in a BorderContainer directly, but has its height and width explicitly set to 100%. This works and the StackContainer is resized correctly on browser maximise. The direct children of the stackcontainer are BorderContainers and it is these BorderContainers that do not get resized when the StackContainer is resized. One point to note is that when the StackContainer is created in markup, the stackcontainer children are empty divs. These divs are then used as placeholders for custom widget creation, e.g. var widget = new com.company.widget(params, placeholderDiv); where placeholderDiv is a direct child of the StackContainer in markup. Should I be adding the programatically created 'widget' to the stackcontainer using addChild instead?

  • c# winforms events restore textbox contents on escape

    - by aj3jr
    Using c# in 2008 Express. I have a textbox containing a path. I append a "\" at the end on Leave Event. If the user presses 'Escape' key I want the old contents to be restored. When I type over all the text and press 'Escape' I hear a thump and the old text isn't restored.

  • Restore and preserve UIViewController pushed from UINavigationController, no storyboard

    - by user2908112
    I try to restore a simple UIViewController that I pushed from my initial view controller. The first one is preserved, but the second one just disappear when relaunched. I don't use storyboard. I implement the protocol in every view controller and add the restorationIdentifier and restorationClass to each one of them. The second viewController inherit from a third viewController and is initialized from a xib file. I'm not sure if I need to implement the UIViewControllerRestoration to this third since I don't use it directly. My code looks like typically like this: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization self.restorationIdentifier = @"EditNotificationViewController"; self.restorationClass = [self class]; } return self; } -(void)encodeRestorableStateWithCoder:(NSCoder *)coder { } -(void)decodeRestorableStateWithCoder:(NSCoder *)coder { } +(UIViewController *)viewControllerWithRestorationIdentifierPath:(NSArray *)identifierComponents coder:(NSCoder *)coder { EditNotificationViewController* envc = [[EditNotificationViewController alloc] initWithNibName:@"SearchFormViewController" bundle:nil]; return envc; } Should perhaps the navigationController be subclassed so it too can inherit from UIViewControllerRestoration?

  • UIIMageView, warning: check_safe_call: could not restore current frame

    - by lukya
    Hi, I am changing the image in UIImageView based on accelerometer input. The images are stored in an array. The application runs fine for a while and then crashes. warning: check_safe_call: could not restore current frame I am not using "UIImage ImageNamed" method when populating the array. The total size of all images is around 12 Mb. But individual images are very light (<100 kb) and i am using only one image at a time from the array. Just in case there are any autoreleases, I have allocated a NSAutoreleasePool in view did load and am draining it in the didReceiveMemoryWarning method (which does get called 2, 3 times before the app crashes?). Following is the code that creates images array: //create autorelease pool as we are creating many autoreleased objects NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSMutableArray *finalarr = [[NSMutableArray alloc] initWithCapacity:9]; NSLog(@"start loading"); for(int y = 0; y < 100; y+=10) { NSMutableArray *arr = [[NSMutableArray alloc] initWithCapacity:10]; for(int x = 0; x < 10; x++) { NSString *imageName = [[NSString alloc] initWithFormat:@"0%d",y + x]; UIImage *img = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imageName ofType:@"png"]]; [arr addObject:img]; [imageName release]; [img release]; } [finalarr addObject:arr]; [arr release]; } NSLog(@"done loading"); // Override point for customization after app launch viewController.imagesArray = finalarr; [finalarr release]; //retain the array of images [viewController.imagesArray retain]; //release the aurtorelease pool to free memory taken up by objects enqued for release [pool release]; As the app runs smoothly for a while, which means array creation is definitely not the problem. After this the following method is called from [accelerometer didAccelerate] -(BOOL)setImageForX:(int)x andY:(int)y { [self.imageView setImage:(UIImage*)[(NSArray*)[self.imagesArray objectAtIndex:y] objectAtIndex:x]]; return TRUE; } So the only code being executed is the "UIImageView setImage". But no objects are being created here. Please let me know if the code seems to have any leaks or i am doing something wrong. Thanks, Swapnil

  • How do I rescue a small portion of data from a SQL Server database backup?

    - by Greg
    I have a live database that had some data deleted from it and I need that data back. I have a very recent copy of that database that has already been restored on another machine. Unrelated changes have been made to the live database since the backup, so I do not want to wipe out the live database with a full restore. The data I need is small - just a dozen rows - but those dozen rows each have a couple rows from other tables with foreign keys to it, and those couple rows have god knows how many rows with foreign keys pointing to them, so it would be complicated to restore by hand. Ideally I'd be able to tell the backup copy of the database to select the dozen rows I need, and the transitive closure of everything that they depend on, and everything that depends on them, and export just that data, which I can then import into the live database without touching anything else. What's the best approach to take here? Thanks. Everyone has mentioned sp_generate_inserts. When using this, how do you prevent Identity columns from messing everything up? Do you just turn IDENTITY INSERT on?
