paging

问题 Disclaimer: This question is related to my operating systems class. However, it's not for any specific homework question. I'm just trying to understand. Here's what I think I know about demand paging so far. Each process has its own paging table. This table contains an index of the logical address, its corresponding physical address, and a valid/invalid bit which indicates whether the page is currently loaded into main memory.

问题 I Have a Crystal Report and get the sum of a field like this: Sum({TheField}) and I put it in PageFooter section to have it in all pages but if the report has multiple pages it shows the sum of all fields and I need to get the sum per page.

问题 Ok. here is the story: I have a UIWebView in full screen, width = 768 It loads several images and those images are in one line, which means the UIWebView will scroll only horizontally.

I won't scale them down and if I scroll the UIWebView, from the 2nd page on, always 132points of previous image will show. This is

问题 I've gone through several articles and tutorials, but I just can't figure this out. Everything basically says, "oh just turn on AllowPaging, and you're done!" When I do that, yes, I can see the paging controls under the GridView in the Design View, but when I compile, I can't see the page numbers in the running site. One thing I noticed different from all of the examples, is that I do the data work from the code-behind. Therefore my GridView is simply: <asp:GridView ID="gvlatest" runat=

问题 I've got an web app in ASP.NET 2.0 in which I need to do paging. My method of data access is to pull a DataSet out of a database call, then convert that to a List<Foo> (where Foo is my type I'm pulling out of the DB) and bind my GridView to it.
