Invalid usage of the option NEXT in the FETCH statement. How can I modify my query for sql server 2008? One more question. How can I write a stored procedure for listing pages

MVVM paging & sorting

最后都变了- 提交于 2019-12-03 17:58:02
问题 I am struggling with finding an adequate solution to impletmenting Sorting and Paging for a WPF DataGrid that conforms to the MVVM P&P. The following example illustrates an effective way to implement paging which follows MVVM practices, but the custom implementation of sorting (which is required once you implement paging) does not follow MVVM: http://www.eggheadcafe.com/tutorials/aspnet/8a2ea78b-f1e3-45b4-93ef-32b2d802ae17/wpf-datagrid-custom-pagin.aspx I currently have a DataGrid bound to a

Calculating number of page faults for 2-d array

心不动则不痛 提交于 2019-12-03 16:51:56
问题 I am trying to study for an exam..and I found this example but can't understand how they got the answer. Can anyone explain it please? Question: Consider the two-dimensional array A: int A[][] = new int[100][100]; where A[0][0] is at location 200 in a paged memory system with pages of size 200. A small process that manipulates the matrix resides in the page 0 (location 0 to 199). Thus every instruction fetch will be from page 0. For two page frames, how many page faults are generated by the

How to speed up scrolling in UIScrollView? [closed]

风流意气都作罢 提交于 2019-12-03 16:09:55
I want to make paging/scrolling in UIScrollView to be faster, so when the user lefts his finger the next page will come faster than normal regardless the speed of the acceleration. Thanks in advance Tweak the decelerationRate of your UIScrollView. More reading: UIScrollView Class Reference If I understand your question correctly, you've setup the ScrollView to snap to pages (pagingEnabled = YES). When the the user lifts their finger you want it to snap to the closest page quicker than what it currently does? If that's what you're trying to accomplish, this is what I recommend: DISABLE

ListView with DataPager not working

不羁的心 提交于 2019-12-03 15:14:38
问题 From everything I've read, it seemed that adding paging to a ListView control should be dead simple, but it's not working for me. After adding the ListView and DataPager controls to the form and wiring them together, I'm getting very odd behavior. The DataPager correctly limits the ListView's page size, but clicking the paging buttons doesn't affect the ListView at all. The paging buttons seem to think they are doing they're job, as the last button is disabled when you go to the last page,

Best practice for WCF service with large amounts of data?

时光总嘲笑我的痴心妄想 提交于 2019-12-03 14:19:06
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 only a reasonable number of entities (from just a few instances up to a couple of thousand). But

Demand Paging: Calculating effective memory access time

六月ゝ 毕业季﹏ 提交于 2019-12-03 13:56:33
问题 I can't understand the answer to this question: Consider an OS using one level of paging with TLB registers. If the page fault rate is 10% and dirty pages should be reloaded when needed, calculate the effective access time if: TLB Lookup = 20 ns TLB Hit ratio = 80% Memory access time = 75 ns Swap page time = 500,000 ns 50% of pages are dirty. Answer: T = 0.8(TLB+MEM) + 0.2 ( 0.9[TLB+MEM+MEM] + 0.1[TLB+MEM + 0.5(Disk) + 0.5(2Disk+MEM)] ) = 15,110 ns Can you explain why? 回答1: In this context

kernel virtual address translation

a 夏天 提交于 2019-12-03 13:15:40
问题 Considering Linux and 32 bit x86 arch there is 3:1 divide of the accessible 4GB address space. The user space is allocated 0-3 Gb while 3-4 Gb is allocated to kernel. How does a virtual address that is greater than 3Gb and hence lies into the kernel address space is transformed to the physical address? Does page tables would come into picture? 回答1: There is some information in Mel Gorman's book Understanding the Linux Virtual Memory Manager. The short answer: Yes, the kernel sets up page

UICollectionView Auto Scroll Paging

Deadly 提交于 2019-12-03 10:09:20
my project have a UIcollectionView. This Horizontal paging and have four object. i’m want my collectionView Auto Scroll Paging. which use methods? As for theory, I just explain the key point. For example, if you want to auto-cycle display 5 images in somewhere, just as ads bar. You can create a UICollectionView with 100 sections, and there're 5 items in every section. After creating UICollectionView, set its original position is equal to the 50th section 0th item(middle of MaxSections ) so that you can scroll to left or right. Don't worry it will ends, because I have reset the position equal
