  • How to make a thread try to reconnect to the Database x times using JDBCTemplate

    - by gillJ
    Hi, I have a single thread trying to connect to a database using JDBCTemplate as follows: JDBCTemplate jdbcTemplate = new JdbcTemplate(dataSource); try{ jdbcTemplate.execute(new CallableStatementCreator() { @Override public CallableStatement createCallableStatement(Connection con) throws SQLException { return con.prepareCall(query); } }, new CallableStatementCallback() { @Override public Object doInCallableStatement(CallableStatement cs) throws SQLException { cs.setString(1, subscriberID); cs.execute(); return null; } }); } catch (DataAccessException dae) { throw new CougarFrameworkException( "Problem removing subscriber from events queue: " + subscriberID, dae); } I want to make sure that if the above code throws DataAccessException or SQLException, the thread waits a few seconds and tries to re-connect, say 5 more times and then gives up. How can I achieve this? Also, if during execution the database goes down and comes up again, how can i ensure that my program recovers from this and continues running instead of throwing an exception and exiting?

  • Property in a Windows Forms form class only accessable after Load event

    - by Spooky2010
    I'm instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ?

  • How to turn this linq query to lazy loading

    - by Luke101
    I would like to make a certain select item to lazy load latter in my linq query. Here is my query var posts = from p in context.post where p.post_isdeleted == false && p.post_parentid == null select new { p.post_date, p.post_id, p.post_titleslug, p.post_votecount, FavoriteCount = context.PostVotes.Where(x => x.PostVote_postid == p.post_id).Count() //this should load latter }; I have deleted the FavoriteCount item in the select query and would like it to ba added later based on certain conditions. Here is the way I have it lazy loaded if (GetFavoriteInfo) { posts = posts.Select(x => new { FavoriteCount = context.PostVotes.Where(y => y.PostVote_postid == x.post_id).Count() }); } I am getting a syntax error with this the above query. How do I fix this

  • WPF Image Button formatting

    - by Sonic Soul
    If I create a button with an image inside, it gets blown up to much larger size than the image. If i try to constrain the size of image, and container button, the image gets cut off: <Button Background="Transparent" Width="18" Height="18" Margin="0,0,0,0" Padding="0,0,0,0" BorderBrush="{x:Null}"> <Image Width="16" Height="16" /> </Button> Native image size is 16x16. Here the button is 18x18 with 0 padding, yet the image still gets cut-off on right/bottom. how can i make the entire button be exactly the size of the image w/out any cut off?

  • In WPF using a ListView is there an elegant way to auto resize items?

    - by Justin
    I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?

  • NHibernate - EventListener for SaveOrUpdateCopy

    - by t-kehl
    Hi. I do Update with SaveOrUpdateCopy(). Now, I have attached an event for this: this.EventListeners.SaveOrUpdateCopyEventListeners = new IMergeEventListener[] { new AuditableSaveOrUpdateCopyEventListener() }; In the AuditableSaveOrUpdateCopyEventListener, I have inherited from DefaultSaveOrUpdateCopyEventListener and overriden OnMerge(): public class AuditableSaveOrUpdateCopyEventListener : DefaultSaveOrUpdateCopyEventListener { public override void OnMerge(MergeEvent evt) { this.AddAuditableData(evt); base.OnMerge(evt); } public override void OnMerge(MergeEvent evt, System.Collections.IDictionary copyCache) { this.AddAuditableData(evt); base.OnMerge(evt, copyCache); } private void AddAuditableData(MergeEvent evt) { var entity = evt.Original as AuditableEntityBase; if (entity != null) { ... } } } But when I now change properties in entity, they will not be saved to the database. Can someone give me a tip, how I can add my auditable-data for SaveOrUpdateCopy? Thank you. Best Regards, Thomas

  • display a confirmation popup on button click based on condition

    - by Raaz
    I have a p:commandButton on click of which I need to add a few values to a list. In my managed bean, I'm validating the value that has to be added, and if it validates to false, I have to display a confirmation popup. This is my code - <p:commandButton id="add" value="Add" type="submit" action="#{bean.doAdd}" ajax="false" update=":List"/> And in the bean, on click of the "Add" button, public String doAdd() throws Exception { if(response != null) { if(keyList.contains(response)) { if(!responseList.contains(response)) { responseList.add(response); } } else { //Have to display confirmation popup. } response = ""; } return response; } I'm using jsf 2.0 and primefaces 3.0. Can someone please tell me how to display the popup from the bean?

  • Newbie PHP coding problem: header function (maybe, I need someone to check my code)

    - by Haskella
    Hi, consider the following PHP code: <?php $searchsport = $_REQUEST['sport']; $sportarray = array( "Football" => "Fb01", "Cricket" => "ck32", "Tennis" => "Tn43", ); header("Location: ".$sportarray[$searchsport].".html"); //directs user to the corresponding page they searched if ($searchsport == NULL) { header("Location: youtypednothing.html"); //directs user to a page I've set up to warn them if they've entered nothing } else { header("Location: sportdoesnotexist.html"); //if sport isn't in my root, a warning will appear } ?> I think the code comments are self-explanatory, basically when I type Tennis on my form.html it will send data to this php file and process and direct me to Tn43.html which is my tennis page. Unfortunately, it doesn't work and I really want to know why... (I know I've made some huge silly mistake). PS: Is header the right function to use when doing some redirecting?

  • Regex to allow all php files except one

    - by Tim
    Hi all, I have this regex that allow all php files : ^.*\.([Pp][Hh][Pp]) how can I exclude a specific file, for example test.php ? Thanks for your answer, Best regards [edit] I omit to say that it is a reg from a htaccess file, the /i doesn't seems to work, and the ? neither. [Edit2] the purpose is to grant access to authenticated users, except for one file that has to be allowed for everyone. So I've done : <Files ~ "^.*\.([Pp][Hh][Pp])$"> AuthUserFile /directory/.htpasswd AuthGroupFile /dev/null AuthName "Please log in ..." AuthType Basic require valid-user </Files> So, all php files require valid user. I would like to add an exception for a specific file, says test.php

  • IE error with jquery counter plugin

    - by Mankey
    I've implemented a jquery counter script (count up from say 50 to 100 with different increments) that I found from this question: jQuery counter to count up to a target number The scripts works great except for in Internet Explorer 8 (and possibly other IE versions?). Here's an error message from IE with the URL to the creator of the script's demo. Message: 'undefined' is null or not an object Line: 32 Char: 17 Code: 0 URI: http://www.ulmanen.fi/stuff/counter.php I'm just wondering if anyone know how this can be fixed. I'm guessing it has to do with el.html() not finding any data but I can't really figure this out. Thanks for any help ^^ I would reply to that post if I could but I can't seem to find any way of doing so (I'm new to stackoverflow, I think I lack privileges).

  • Masking to Transparent returns empty image

    - by Tibi
    Hi there, I'm trying to put white color in my images to transparent with the following code. Problem is that "CGImageRef maskedTransparent" is blank. I don't understand because the code I'm using is nearly a copy paste from the doc ... Any idea ? (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage { CGImageRef maskRef = maskImage.CGImage; CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef), CGImageGetHeight(maskRef), CGImageGetBitsPerComponent(maskRef), CGImageGetBitsPerPixel(maskRef), CGImageGetBytesPerRow(maskRef), CGImageGetDataProvider(maskRef), NULL, false); CGImageRef masked = CGImageCreateWithMask([image CGImage], mask); //Array defining min & max RGB values to be transformed to transparent colors. float maskingMinMax[6] = {255, 255, 255, 255, 255, 255}; //masking image to remove range in maskinLinMax CGImageRef maskedTransparent = CGImageCreateWithMaskingColors(masked, maskingMinMax); return [UIImage imageWithCGImage:maskedTransparent]; }

  • Assembly Version Conflicts with What is Already Bound

    - by davemackey
    I'm running Microsoft LightSwitch Beta 1 and have been creating an application which has been going great, but then I tried debugging after making a few minor changes and received the following error: "Could not load file or assembly 'SW_Resources.Commom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The requested assembly version conflicts with what is already bound in the app domain or specified in the manifest. (Exception from HRESULT: 0x80131053)" I've tried emptying my cache in Firefox and IE but that doesn't seem to make any difference. I did discover if I right-clicked on the Solution and changed the version from 0.1 to 1.0 then it works fine. I had changed it to 0.1 b/c I wanted to reflect that it wasn't a release version...any thoughts on how to get around this issue the right way?

  • More strict query yields more results?

    - by Mark
    I've got a query that looks like this affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) But when I restrict it more by adding referrals__user__date_joined__gt=start_date to the filter, I get even higher referral counts. I'm trying to count the number of people a user has referred within a time period. The relevant model looks like this: class Profile(models.Model): user = models.ForeignKey(User, unique=True, related_name='profile') referred_by = models.ForeignKey(User, null=True, blank=True, related_name='referrals') In contrast, when I try it like this: affiliates = User.objects \ .exclude(referrals__user__date_joined__lte=sd, referrals__user__date_joined__gt=ed) \ .annotate(referral_count=Count('referrals')) \ .filter(referral_count__gt=0) The exclude statement seems to do nothing... the counts don't change (should be 0 if no referred users have joined within that time period, but it isn't).

  • MySQL Trigger with dynamic table name

    - by Thomas
    I've look around a bit and can't quite find an answer to my problem: I want a trigger to execute after an insert on a table and to take that data that is being inserted and do two things Create a new table from the client id and partner id Insert the 'data' that just was inserted into the new table I am fairly new to the Stored procedures and triggers so I came up with this but am having difficulty debugging it: delimiter $$ CREATE TRIGGER trg_creas_insert BEFORE INSERT ON tracking.creas for each row BEGIN DECLARE @tableName varchar(40); DECLARE @createStmnt mediumtext; SET @tableName = concat('crea_','_', NEW.idClient_crea,'_',NEW.idPartenaire_crea); SET @createStmnt = concat('CREATE TABLE IF NOT EXISTS', @tableName, '( `data_crea` mediumtext NOT NULL ) ENGINE=MyISAM AUTO_INCREMENT=29483330 DEFAULT CHARSET=utf8 PACK_KEYS=0'); PREPARE stmt FROM @createStmnt; EXECUTE stmt; INSERT INTO @tableName (data_crea) values (NEW.data_crea); END$$ delimiter ; Thoughts?

  • Order of calls to set functions when invoking a flex component

    - by Jason
    I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions: [Bindable] private var _dataSetLoader:DataSetLoader; public function get dataSetLoader():DataSetLoader {return _dataSetLoader;} public function set dataSetLoader(dataSetLoader:DataSetLoader):void { trace("setting dSL"); _dataSetLoader = dataSetLoader; } [Bindable] private var _table:Table = null; public function set table(table:Table):void { trace("setting table"); _table = table; _dataSetLoader.load(_table.definition.id, "viewData", _table.definition.id); } This component is nested in another component as follows: <ve:TableDataViewer width="100%" height="100%" paddingTop="10" dataSetLoader="{_openTable.dataSetLoader}" table="{_openTable.table}"/> Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function. So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?

  • SHA-256 encryption wrong result in Android

    I am trying to encrypt 12345 using 1111 as salt using SHA-256 encoding and the answer I get is: 010def5ed854d162aa19309479f3ca44dc7563232ff072d1c87bd85943d0e930 which is not same as the value returned by this site: http://hash.online-convert.com/sha256-generator Here's the code snippet: public String getHashValue(String entity, String salt){ byte[] hashValue = null; try { MessageDigest digest = MessageDigest.getInstance("SHA-256"); digest.update(entity.getBytes("UTF-8")); digest.update(salt.getBytes("UTF-8")); hashValue = digest.digest(); } catch (NoSuchAlgorithmException e) { Log.i(TAG, "Exception "+e.getMessage()); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } return BasicUtil.byteArrayToHexString(hashValue); } I have verified my printing method with a sample from SO and result is fine. Can someone tell me what's wrong here? And just to clarify - when I encrypt same value & salt in iOS code, the returned value is same as the value given by the converting site.

  • java.util.Date.toString() is printing out wrong format

    The following code prints out "vmtDataOrig.creationdate=2012-11-03" VmtData vmtDataOrig = VmtDataDao.getInstance().loadVmt(1); System.out.println("vmtDataOrig.creationdate=" + vmtDataOrig.getCreationDate().toString()); Here is the definition of the creationDate field in the VmtData class: private Date creationDate = null; Here is the hibernate mapping of the creationDate field to the database table column: <property name="creationDate" column="CREATIONDATE" type="date"/> The CREATIONDATE column in the MySQL database table is of type "date", and for the record retrieved it has the value "2012-11-03". The Javadoc for the java.util.Date.toString() method says it is supposed to print the Date object in the form "dow mon dd hh:mm:ss zzz yyyy". Anyone know why it is printing it out in the form "yyyy-MM-dd"?

  • Silverlight: Use reflection to get the BindingExpression (and value) for controls having a ContentPr

    - by sfx
    Hello, I need to use reflection to get the binding value in a control that is a DataGridTemplateColumn (e.g HyperLinkButton). Does anyone know how I might do this? It seems simple enough to do this with a TextBlock because it has a “TextProperty” dependency property, but I can’t seem to get a binding expression from a control that does not have an immediate “TextProperty”. Here is the code I’m using to acquire the binding expression for a TextBlock: FrameworkElement fe = (FrameworkElement)dependencyObj; FieldInfo fi = fe.GetType().GetField("TextProperty"); BindingExpression bindingExpression = fe.GetBindingExpression((DependencyProperty)fi.GetValue(null)) However, the following code never works for a dependency object that is a HyperLinkButton: FieldInfo fi = fe.GetType().GetField("ContentProperty"); Does anyone know how I might be able to get the BindingExpression (and binding value) for the content of a HyperLinkButton? Cheers, sfx
