问题 I have seen the WWDC-104 video showing UIScrollView for photos. I have downloaded the Sample code too. In my app the Structure is as follows, (Root Class)Class A ---> Class B -----------> PhotoViewController(Containing ScrollView) I am calling the PhotoViewController class by using presentModalViewController method in Class B. But with every swipe the new Image shifts to right on the view. A black vertical strip is visible on left of the image which widens with each swipe. So after 6 to 8

问题 To access an instance of a User in a restful web-service the url is structured as shown in the curl request below: curl -v -X GET -s "$BASE_URL/User/${customer_id}.json" If I wanted to specify all User entities or page through a range of User entities, such as the first 50 Users in my database, how would I structure my request so that it is compliant with REST ??? 回答1: You should start by trying to de-emphasize the meaning of the characters in a URI. While nice, pretty and readable URIs are a

问题 Delphi 6 Prof. We have many applications. The programs have 8-12 MB size. In this period we many times got reports about "Invalid stream format" errors. We use shared Windows (or Linux) folders to store the applications, and users running them from these directories with links. This meaning that OS is paging the files, and loading the needed parts only. Formerly we got C000006 exceptions. As I know this meaning that the file paging (loading) failed on any network problem (timeout, etc). Now

问题 From what I understand pages come from overlays which are clusters of memory spaces generated by Virtual Memory. But I don't understand what frames are or how they relate. Can anyone explain what page and frame is and how it works? 回答1: Page frame is a physical property of the main memory. Whereas, virtual page is... virtual. frame 0 frame 1 frame 2 frame 3 frame 4 ---------------------------------------------- | | | | | | | | | | | | ---------------------------------------------- Main Memory

问题 We have a WCF service that is used for querying an underlying data store (SQL Server 2005 right now). This service may return rather large amounts of data; 60000+ instances of our entity class that contains ~20 properties. The properties are mostly primitives such as string, int, DateTime with a couple pointing at other entities that may in turn point at others; those hierarchies are not very deep though. One application that is consuming this service will typically make queries that return

问题 I have a functioning Knockout template for some pagination UI that works with a Knockout-based shared data grid. This template renders an HREF for each "page" of data in the grid. The template works but it's klunky because if I fetch a lot of data, then I end up with dozens and dozens of navigation page links below the grid. Here's the current template: <div class="idTemplate_ko_simpleGrid_pageLinks"> <p> <span>Go to page:</span> <!-- ko foreach: ko.utils.range(0, maxPageIndex) --> <a href=

问题 I am trying Dapper ORM and I am querying a a Posts table. But I would like to get paged results ... 1 - How can I do this? Isn't there a helper for this? 2 - Can Dapper Query return an IQueryable? Thank You, Miguel 回答1: 1) Dapper doesn't have a built-in pagination feature. But its not too hard to implement it directly in the query. Example: SELECT * FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY InsertDate) AS RowNum, * FROM Posts WHERE InsertDate >= '1900-01-01' ) AS result WHERE RowNum >= 1 //

问题 Edit: See the answer below. I finally give up and come here to ask you for my problem... I'm using a UIScrollView for a scrolling menus with little icons. On each page, with paging enabled, there's an icon in the center, and 2 and a half other visible icons on the left and right. I can move from one icon to its neighbour, and that is fine, but the point is that if I do a fast scrolling, it will not move from more than 3 icons, which is the width of the screen.

问题 I have a telerik radgrid-control on my page for showing a list of articles. If I click a page, then an article and then back to the list again I am back at the first page instead of the one I was at before. Is there a solution for this? 回答1: I'm assuming you're doing a postback and things are server side... This is a 2 step process... First in the OnClick event for clicking on an article, put the page index into a session variable. Second, in the RadGrid's PreRender event get the page index
