  • Changing css-class-wrapper parameter of liferay portlet at runtime

    - by 2DH
    As the title says - I need to change css-class-wrapper parameter at runtime, preferably in action class. I've found that Portlet interface has setCssClassWrapper method that could probably do what I want, but I can't seem to find any easy way to access current portlet object from my code. Could anyone please give me a hand with what I want to achieve. Thanks.

  • Please help with iPhone Memory & Images, memory usage crashing app

    - by Andrew Gray
    I have an issue with memory usage relating to images and I've searched the docs and watched the videos from cs193p and the iphone dev site on memory mgmt and performance. I've searched online and posted on forums, but I still can't figure it out. The app uses core data and simply lets the user associate text with a picture and stores the list of items in a table view that lets you add and delete items. Clicking on a row shows the image and related text. that's it. Everything runs fine on the simulator and on the device as well. I ran the analyzer and it looked good, so i then starting looking at performance. I ran leaks and everything looked good. My issue is when running Object Allocations as every time i select a row and the view with the image is shown, the live bytes jumps up a few MB and never goes down and my app eventually crashes due to memory usage. Sorting the live bytes column, i see 2 2.72MB mallocs (5.45Mb total), 14 CFDatas (3.58MB total), 1 2.74MB malloc and everything else is real small. the problem is all the related info in instruments is really technical and all the problem solving examples i've seen are just missing a release and nothing complicated. Instruments shows Core Data as the responsible library for all but one (libsqlite3.dylib the other) with [NSSQLCore _prepareResultsFromResultSet:usingFetchPlan:withMatchingRows:] as the caller for all but one (fetchResultSetReallocCurrentRow the other) and im just not sure how to track down what the problem is. i've looked at the stack traces and opened the last instance of my code and found 2 culprits (below). I havent been able to get any responses at all on this, so if anyone has any tips or pointers, I'd really appreciate it!!!! //this is from view controller that shows the title and image - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; self.title = item.title; self.itemTitleTextField.text = item.title; if ([item.notes length] == 0) { self.itemNotesTextView.hidden = YES; } else { self.itemNotesTextView.text = item.notes; } //this is the line instruments points to UIImage *image = item.photo.image; itemPhoto.image = image; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { // Delete the managed object for the given index path NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; [context deleteObject:[fetchedResultsController objectAtIndexPath:indexPath]]; // Save the context. NSError *error = nil; if (![context save:&error]) //this is the line instruments points to { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); exit(-1); } } }

  • PHP mysqli error return time

    - by Dori
    Hello. Can i ask a fundamental question. Why when I try to create a new mysqli object in php with invalid database infomation (say an incorrect database name) does it not return an error intstantly? I usually program server stuff in Java and something like this would throw back an error strait away, not after 20 seconds or so. For example $conn = new mysqli($host, $username, $password, $database); Thanks!

  • How can I use linq to initialize an array of repeated elements?

    - by Eric
    At present, I'm using something like this to build a list of 10 objects: myList = (from _ in Enumerable.Range(0, 9) select new MyObject {...}).toList() This is based off my python background, where I'd write: myList = [MyObject(...) for _ in range(10)] Note that I want my list to contain 10 instances of my object, not the same instance 10 times. Is this still a sensible way to do things in C#? Is there a cost to doing it this way over a simple for loop?

  • ASP.Net 4.0 - Response required in SiteMap building?

    - by Nick Craver
    I'm running into an issue upgrading a project to .Net 4.0...and having trouble finding any reason for the issue (or at least, the change causing it). Given the freshness of 4.0, not a lot of blogs out there for issues yet, so I'm hoping someone here has an idea. Preface: this is a Web Forms application, coming from 3.5 SP1 to 4.0. In the Application_Start event we're iterating through the SiteMap and constructing routes based off data there (prettifying URLs mostly with some utility added), that part isn't failing though...or at least isn't not getting that far. It seems that calling the SiteMap.RootNode (inside application_start) causes 4.0 to eat it, since the XmlSiteMapProvider.GetNodeFromXmlNode method has been changed, looking in reflector you can see it's hitting HttpResponse.ApplyAppPathModifier here: str2 = HttpContext.Current.Response.ApplyAppPathModifier(str2); HttpResponse wasn't used at all in this method in the 2.0 CLR, so what we had worked fine, in 4.0 though, that method is called as a result of this stack: [HttpException (0x80004005): Response is not available in this context.] System.Web.XmlSiteMapProvider.GetNodeFromXmlNode(XmlNode xmlNode, Queue queue) System.Web.XmlSiteMapProvider.ConvertFromXmlNode(Queue queue) System.Web.XmlSiteMapProvider.BuildSiteMap() System.Web.XmlSiteMapProvider.get_RootNode() System.Web.SiteMap.get_RootNode() Since Response isn't available here in 4.0, we get an error. To reproduce this, you can narrow the test case down to this in global: protected void Application_Start(object sender, EventArgs e) { var s = SiteMap.RootNode; //Kaboom! //or just var r = Context.Response; //or var r = HttpContext.Current.Response; //all result in the same "not available" error } Question: Am I missing something obvious here? Or, is there another event added in 4.0 that's recommended for anything related to SiteMap on startup? For anyone curious/willing to help, I've created a very minimal project (a default VS 2010 ASP.Net 4.0 site, all the bells & whistles removed and only a blank sitemap and the Application_Start code added). It's a small 10kb zip available here: http://www.ncraver.com/Test/SiteMapTest.zip Update: Not a great solution, but the current work-around is to do the work in Application_BeginRequest, like this: private static bool routesRegistered = false; protected void Application_BeginRequest(object sender, EventArgs e) { if (!routesRegistered) { Application.Lock(); if (!routesRegistered) RouteManager.RegisterRoutes(RouteTable.Routes); routesRegistered = true; Application.UnLock(); } } I don't like this particularly, feels like an abuse of the event to bypass the issue. Does anyone have at least a better work-around, since the .Net 4 behavior with SiteMap is not likely to change?

  • Spark show logged in user

    - by Jose
    How do I show the username of the person logged in within a Spark View? The default MVC view engine had a Page object that you could get the info from. How would I do that in spark? I know that I could put the info into the viewdata dictionary, which is probably the best, but I don't want to have to write ViewData["User"] = myUser; before I return from EVERY action method. I'd like some feedback

    I created a VB.NET Windows Forms Application in Visual Studio 2008. When I run my program from the command-line, I get no output (only the next prompt). Why? Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Debug.Write("Foo") Debug.Flush() Console.WriteLine("foo") Console.Beep(800, 100) 'confirm this function is called' Me.Close() End Sub

    - by Mike Clark
    In VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example: With foo .bar() .reset(true) myVar = .getName() End With Is there any such syntax within Java? Thanks!

  • VBA Excel - Workbook_SheetChange

    - by user2947014
    Hopefully this question hasn't already been asked, I tried searching for an answer and couldn't find anything. This is probably a simple question, but I am writing my first macro in excel and am having a problem that I can't find out a solution to. I wrote a couple of macros that basically sum up columns dynamically (so that the number of rows can change and the formula moves down automatically) based on a value in another column of the same row, and I call those macros from the event Workbook_SheetChange. The problem I'm having is, I change a cell's value from my macro to display the result of the sum, and this then calls Workbook_SheetChange again, which I do not want. Right now it works, but I can trace it and see that Workbook_SheetChange is being called multiple times. This is preventing me from adding other cell changes to the macros, because then it results in an infinite loop. I want the macros to run every time a change is made to the sheet, but I don't see any way around allowing the macros to change a cell's value, so I don't know what to do. I will paste my code below, in case it is helpful. Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range) Dim Row As Long Dim Col As Long Row = Target.Row Col = Target.Column If Col <> 7 Then Range("G" & Row).Select Selection.Formula = "=IF(F" & Row & "=""Win"",E" & Row & ",IF(F" & Row & "=""Loss"",-D" & Row & ",0))" Target.Select End If Call SumRiskColumn End Sub Private Sub Workbook_SheetCalculate(ByVal Sh As Object) Call SumOutcomeColumn End Sub Sub SumOutcomeColumn() Dim N As Long N = Cells(Rows.Count, "A").End(xlUp).Row Cells(N + 1, "G").Formula = "=SUM(G2:G" & N & ")" End Sub Sub SumRiskColumn() Dim N As Long N = Cells(Rows.Count, "A").End(xlUp).Row Dim CurrTotalRisk As Long CurrTotalRisk = 0 For i = 2 To N If IsEmpty(ActiveSheet.Cells(i, 6)) And Not IsEmpty(ActiveSheet.Cells(i, 1)) And Not IsEmpty(ActiveSheet.Cells(i, 2)) And Not IsEmpty(ActiveSheet.Cells(i, 3)) Then CurrTotalRisk = CurrTotalRisk + ActiveSheet.Cells(i, 4).Value End If Next i Cells(N + 1, "D").Value = CurrTotalRisk End Sub Thank you for any help you can give me! I really appreciate it.

  • Does OpenGL ES support environment shaders?

    - by Soviut
    I want to make metallic 3d object that appears to be reflective. I want to accomplish this using an environment shader that uses either a sphere or cube map that I can assign an image or texture as the "reflection" source. Does OpenGL ES on the iPhone support this in any versions?

    Hi, someone can tell me why this is incorrect as a singleton pattern: class preSingleton(object): def __call__(self): return self singleton = preSingleton() a = singleton() b = singleton() print a==b a.var_in_a = 100 b.var_in_b = 'hello' print a.var_in_b print b.var_in_a Edit: The above code prints: True hello 100 thank you very much
