spring - Converting Object to Class object -

-

In my Spring MVC project I'm using Hibernate, using the criteria API Group I and order by clause I'm implementing Query successfully executed DB and also brings results, but an array of object -

The criteria API 

  Criteria criteria = session.createCriteria (DashboardSubindicatorSubmission's code .class, "DashboardSubindicatorSubmission") .setProjection (Projections.projectionList () .add (Projections.sum ( "InputValue"). as ( "InputValue")) Kadd (ProjectionskgroupProperty ( "FkAccademicYearId")) Kadd (estimated .groupProperty ( "fkAssessmentPlanID")) .add (Projections.groupProperty ( "fkSubindicatorID")) .add (Projections.groupProperty ( "InputTitle"))) .addOrder (Order.asc ( "fkAccademicYearId")) .addOrder ( Order .asc ("fkAssessmentPlanID"). Theodor (o Order .asc ("Inputtail")); & Lt; DashboardSubindicatorSubmission & gt; DashboardSubandicatorSubmissionList = (list & lt; dashboard SUBIDCETER support & gt;) criteria.list (); Session.flush (); Transaction.commit (); Return dashboardSubandicatorSubmissionist;   
 I'm casting  from  list to criteria.list ()  & lt; DashboardSubindicatorSubmission & gt;  but when I try to  dashboardSubindicatorSubmissionList.get (I)  This gives me an exception controller  java.lang.ClassCastException: [Ljava.lang.Object; Mkcl.accreditation.model.DashboardSubindicatorSubmission can not be molded into   
 I come to know that, though im  listing & lt casting it ;. DashboardSubindicatorSubmission & gt; [ is still a list of your  object]  thats why can not i  DashboardSubindicatorSubmissionListkget (I)  do, because for me  DashboardSubindicatorSubmission Returns the object of .  (I'm right if I am wrong)   
 How can I change my result to the  Dashboard SUBIDCitersSubmission  class list? ResultTransformer () Does this help me in this case?  
  
 
 
 You have two options when you use the estimates, then be respected in every field in hibernation Do not know how to do this because it uses the name of each area to construct objects and it does not yet know the name.  
 In this way, group your first option field so that they match the name of the object properties. It is necessary, even if the string used in the projection is already the name of the object field. Such as: .add (Projections.groupProperty ("fkAssessmentPlanID"), "Other") / etc. (Projections. GroupProperty ("fkAccademicYearId"), "fkAccademicYearId" The other option is to suggest that you do yourself self-implementation of ResultTransformer. I consider it an interesting option if you want to remove other objects in this query. As you do a report.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
