paging

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Can you find a good tutorial or documentation about achieving a good pagination in a Google App Engine Objectify world? I found some posts: http://groups.google.com/group/objectify-appengine/browse_thread/thread/b640b5d377b620b4 But nothing seems to help me. Is there some sort of LIMIT query? The post you linked to describes the correct way to do pagination: Using cursors. You can fetch using offsets and limits,

Although, questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a GridView which is contained in a tab container AJAX control which itself is inside an UpdatePanel . Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging (e.g.) after I click on page 2, the GridView hides itself. here is my PageIndexChanging() method: protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; GridView1.DataBind();

I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows: Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging gvEvents.PageIndex = e.NewPageIndex gvEvents.DataBind() This worked beautifully until I added an AJAX update

I'm using spring-data-rest with JpaRepository to create the Rest-Endpoints. By default, paging is enabled for all JpaRepository , what is a good thing. But I have a legacy application that we port to our new stack that does not support paging. I would like to disable paging depending on an URL-Parameter to still be able to use paging in new application code. I tried various approaches to expose the resources with and without paging: Use CrudRepository : Results in only having an unpaged endpoint and the method flush is missing. Override the List<T> findAll() method in my repository interface

I'm writing an Android app that reads a single text file and display it on a TextView . What I'm doing right now is read the whole file into a String (using BufferedReader and StringBuilder ) and display it on a TextView using setText(string) . A 700KB text file can take about 2 to 3 seconds before it is being displayed on the screen. But I've used some other ebook readers on the market and they can display the same text almost instantly. Anyone know how I can achieve this? Thanks you. Edit : Many suggest ListView, but it doesn't work for my particular case. This is from my reply to one of the

Possible Duplicate: Can I tell Linux not to swap out a particular processes' memory? I want to allocate a chunk of memory in Linux and be sure that it will get no #GP or #PF faults. Regarding #GP, it's my responsibility as a programmer to ensure that I do not exceed any bounds. However, #PF are the the responsibility of the OS, since it can choose whether or not to evict a page. I imagine that if I use the same page frequently, the OS will be smart enough not to evict it. However, if I want to allocate a large block of memory, then it'll take me a while to reach some of the pages, and I don't

I'm writing an array-backed hashtable in Java, where the type of key and value are Object; no other guarantee. The easiest way for me code-wise is to create an object to hold them: public class Pair { public Object key; public Object value; } And then create an array public Pair[] storage = new Pair[8]; But how does the jvm treat that in memory? Which is to say, will the array actually: be an array of pointers to Pair() objects sitting elsewhere, or contain the actual data? edit Since the objects are instantiated later as new Pair(), they're randomly placed in the heap. Is there any good way
